Gender differences in the engagement of work activities across sectors are important elements of gender inequality in rural livelihoods and welfare in developing countries. The role of production technologies, including agricultural mechanization, in addressing gender inequality, is increasingly explored. Knowledge gaps remain, however, including, how agricultural mechanization differentially affect labor engagements across sectors. This study aims to partly fill these knowledge gaps through micro-evidence from 8 countries (Ethiopia, Ghana, Nigeria, Tanzania, India, Nepal, Tajikistan and Vietnam), using several nationally representative panel data and supplementary data, and applying Correlated-Random-Effects Double-Hurdle models with Instrumental-Variables. We find that the use of tractors and/or combine harvesters by the household induces greater shift from farm activities to non-farm activities by female members than by male members. While statistical significance varies, these patterns generally hold consistently across all 8 countries studied. These patterns also seem to hold across different farm sizes. While these are short-term relations, agricultural mechanization proxied by tractor and/or combine harvesters is one of the important contributors to gendered rural livelihood. Future studies should more closely investigate underlying mechanisms and implications of these patterns.

Social protection programs such as cash or food transfers support current poverty and inequality reduction goals, while at the same time enhance future productivity through human capital investments. Yet, the quantification of their overall productivity and equity benefits is challenging. We address this question utilizing a new methodology that quantifies productivity gains from learning as well as an approach for assessing social protection benefits. We do so by combining data on distributional benefits stemming from current poverty reduction in conjunction with future human capital gains in the context of a large-scale national school feeding program in Ghana. We develop a straightforward approach to map effect sizes from randomized controlled studies into broader economic analyses. In addition, we include the often recognized, but seldom quantified, distributional impacts of multi-sectoral investments. Our methodology is relevant to a broad range of social protection programs that have multidimensional benefits spanning both human capital improvements and equity gains.

Background: Low quality diets are a public health problem affecting individuals of all ages worldwide. Nudging for Good (NFG) is a new research project aimed at developing, validating, and examining the feasibility of using artificial intelligence (AI)-based technology to improve adolescent girls' diets in urban Ghana and Vietnam. Objectives: Provide evidence to support the design of a new mobile phone intervention including: a) identifying the demand for mobile app to improve diets in adolescent girls; b) defining the intervention objectives and activities to be delivered via a mobile app; and c) assessing the potential for nudging functionality to be incorporated in the mobile app. Methods: This study used mixed methods including both literature and nutrition-related app reviews, as well as focus group discussions. A literature review was conducted using PubMed and Google Scholar databases, and intervention studies using technology to improve nutrition outcomes of adolescents were included. Nine focus group discussions (five in Ghana and four in Vietnam) were undertaken with 61 girls to gauge smartphone and internet access and use and to obtain feedback on the prototype of a mobile app. Results: Nine studies met the selection criteria for the literature review, including seven randomized control trials (RCTs) and two systematic reviews. The evidence from the literature on how technology-based nutrition interventions should be conducted and what should be the best outcomes of success was mixed. Most of the 22 apps reviewed required manual entry of dietary information, and recommended diets based on motivation to change body weight. In the focus groups discussions, the adolescents suggested modifications on the prototype of the mobile app we presented, and indicated possibility to regularly take pictures of foods and beverages during meal time. Conclusion: We did not find an app available in either the Ghana or Vietnam markets that could improve dietary quality of adolescents without focusing on weight. Most apps available only had manual features to log food intake, which is time consuming. Moreover, adolescents expressed interest in using a new, modified version of the app we presented. We aim at developing a new mobile phone application based on AI technology that gives personalized and reliable nutrition advice to improve adolescent girls’ diets. However, the literature review was not conclusive on what should be the characteristics of an app and how interventions to measure an app’s impact on dietary quality should be conducted.

Livelihoods are changing rapidly in rural areas. Measuring and categorizing peoples’ labor activities in relation to the agricultural sector is important for understanding income earning opportunities and designing effective policy. Conventional data collection methods ask about individuals’ main work activities over the past year. Descriptions are recorded in the field, postcoded, and eventually categorized. This approach is costly to collect, fatiguing for respondents, and may create distortions. We show that a more direct approach, asking respondents to categorize their major work activities themselves, provides similar resulting data despite some caveats and lessons for best enumeration practices. We compare these main activities to a series of yes/no questions about participation in a set of specific work tasks. We find a 12% incidence of “missing” work, whereby individuals who reported participation in at least one but did not have any recorded major activities. Looking by sector of work, women and youth are disproportionately more likely to have agricultural contributions “missed,” while we find no corresponding bias in undercounting of non-agricultural work. Finally, we test the effect of randomly positioning the task-based questions before the listing of major activities but do not find significant effects on the number or type of activities reported.

The triple burden of malnutrition is growing in low- and middle-income countries (LMICs). Increasing access to affordable ultra-processed foods in the food environment is contributing to this problem. While existing explanations for this triple burden of malnutrition have examined demand-side factors of food choices, the supply-side policies relating to the food environment drivers, ideas and actors’ interests have been neglected. Using a case study of Ghana, this analysis combines the Advocacy Coalition Framework with the narrative policy analysis to unpack the supply-side food environment policies and actors driving the triple burden of malnutrition. Applying a mixed methods analysis of the transcripts, the narratives reveal public, private and civil society organization (CSO) coalitions with different ideas and interests in the food environment. In the private sector coalition, food companies engage in aggressive advertising and are driven by profit motives – leading to the supply of more ultra-processed foods. The public sector is failing to regulate the market because of inadequate policies, limited institutional capacities and coordination, enforcement challenges, inadequate resources, and self-interest. Social activism by CSOs, for example, pressuring food companies to deliver healthy foods and holding the government accountable, is also lacking. The result is a triple sector (public, private and CSO) failure in the urban food environment with consequences on the availability of ultra-processed foods. This has long-lasting implications for the reduction of the triple burden of malnutrition and the achievement of zero hunger. To accelerate nutrition-sensitive food environments that deliver healthier food options, we argue that it is critical to entertain the ideas and interests of stakeholders and implement food environment policies that cover private and public sector initiatives, as well as increase consumer awareness.

Governments and international development partners investing over $40 USD billion a year in school meals have shown interest in linking these programs with agriculture sector development, through what has become known as “Home-Grown” school feeding (HGSF). Nevertheless, evidence on the effectiveness of HGSF and agriculture is limited. This article reports on the findings of a three-year cluster randomized trial implemented in 58 districts of Ghana including a panel of 1,668 households. Communities were randomly assigned to 1) standard school meals; 2) HGSF or 3) control with no intervention. Post-intervention, the caterer-level analysis highlighted major challenges related to delayed program disbursements, resulting in a mismatch between budgeted and actual caterer outlay on food purchases per pupil equivalent to approximately 50% of the budgeted per child per day allocation. For caterers, by far the largest procurement channel was through traders, though there is evidence that HGSF may have increased the share of value purchased directly from smallholders. We find no strong evidence that the school feeding program or HGSF affected smallholders market structure, farm, non-farm and household income. When interpreting these null results, it is important to consider the findings of two parallel studies that showed positive effects of this national program on school children’s learning, cognition, and nutrition outcomes. The national program can still be considered as an effective social protection strategy with multiple objectives, even if the agriculture objectives remain aspirational.

Agricultural research and development (R&D) is one component of public investments in the agricultural sector toward food system transformation. Enhancing the effectiveness of agricultural R&D remains critical, given increasingly scarce public resources. Exploring spatial spillover potentials has been one way to enhance the effectiveness of agricultural R&D. Geographical locations of National Agricultural Research Systems (NARS) research activities are recognized as an important factor affecting such spatial spillover potentials. However, evidence is generally limited in Africa south of Sahara (SSA) as to the spillover potentials of NARS-developed technologies. This paper partly aims to fill this knowledge gap by obtaining insights for maize, one of the most commonly grown crops in SSA, using nationally representative farm household data for Ethiopia, Ghana, Nigeria, and Uganda, and spatial agroclimatic data. Building on recent literature, this study proxies spillover potentials by “agroclimatic similarity” (AS) indicators between locations where agricultural R&D for maize is conducted by NARS (research locations) and where each farm household is located (farm locations). Results of the analyses suggest that an indicator of the total factor productivity of maize growing farm households, the land productivity of maize, and the use of improved maize varieties are generally higher in farm locations that share similar agroclimatic conditions with maize research locations of NARS. These patterns hold for all four countries studied, even after controlling for the physical proximity to maize research stations and other farm household characteristics. The findings contribute to better understanding of how geographic locations of public investments affect their overall effectiveness as well as returns in maize production and the agricultural sector in general.

Child labour in agriculture remains a global concern. Agriculture is the sector where most child labour is found. Employment of children mostly relates to farm household poverty in developing countries. This raises the question of the extent to which the modernisation of agriculture prevents the use of child labour while also leading to higher productivity. One of the central questions in this context is whether agricultural mechanisation helps limit children’s employment. Available studies have put forward opposing hypotheses, but rigorous empirical evidence is scant. The present study aims to fill some of this void by studying the evidence from comparable farm household survey data in seven developing countries, including three in Asia (India, Nepal, and Vietnam) and four in sub-Saharan Africa (Ethiopia, Ghana, Nigeria, and Tanzania). Various key findings emerge. First, many children are found to engage in productive activities in studied countries. The prevalence is particularly high in African countries, such as in Ethiopia where more than one third of children aged 5-14 years engage in farm or off-farm work. Second, while the prevalence of child labour in agriculture (i.e., when productive engagement is detrimental to schooling and child growth) is much lower (at 10% or less in seven countries), they are still sizable in absolute terms; at least 6 million children in these countries partake in agricultural work at the expense of opportunities in adulthood. Third, agricultural mechanization, reflected in farm household’s use of machinery such as tractors, significantly reduces the likelihood of use of children’s labour and increases school attendance. Fourth, the measured impacts of mechanization are only modest, however, and likely indirect, that is, dependent on the extent to which mechanization helps improve household income and on local conditions (such as quality of rural infrastructure and accessibility of education and other social services). Overall, promotion of agricultural mechanization can help prevent use of child labour. To be truly impactful, however, related support measures should be embedded in broader strategies to enable agricultural productivity growth and improve livelihoods of poor rural households.

Although women’s empowerment and gender equality are associated with better maternal and child nutrition outcomes, recent systematic reviews find inconclusive evidence. This paper applies a comparable methodology to data on the Women’s Empowerment in Agriculture Index (WEAI), a recent internationally-validated measure based on interviews of women and men within the same household, from six countries in Africa and Asia to identify which dimensions of women’s empowerment are related to household-, women-, and child-level dietary and nutrition outcomes. We examine the relationship between women’s empowerment and household-level food security and dietary diversity; women’s dietary diversity and BMI; and child-related outcomes, controlling for woman, child, and household characteristics. We also test whether women’s empowerment has differential associations for boys and girls. We do not find consistent associations between dimensions of empowerment and food security and nutrition outcomes across countries, but some patterns emerge. Overall empowerment scores are more strongly associated with nutritional outcomes in the South Asian countries in our sample compared to the African ones. Where significant, greater intrahousehold gender equality is associated with better nutritional outcomes. However, different domains have different associations with nutritional outcomes, suggesting that tradeoffs exist: higher workloads are associated with more diverse diets but lower women’s BMI and child anthropometric outcomes. Identifying the overlap between the top contributors to disempowerment and those most strongly related to nutrition outcomes can inform the design and implementation of nutrition-sensitive agricultural programs.

Conservation agriculture techniques can increase agricultural production while decreasing CO2 emissions, yet adoption in the developing world remains low—in part because many years of continuous adoption may be required to realize gains in production. We conduct a framed field experiment in northern Ghana to study how randomly assigned incentives and peer information may affect adoption. Incentives increase adoption, both while they are available and after withdrawal. There is no overall effect of peer information, but we do find evidence that information about long-term adoption increased adoption, particularly when that information shows that production gains have been achieved.

Irrigated agriculture can support food and nutrition security, increase rural employment and incomes and can act as a buffer against growing climate variability and change. However, irrigation development has been slow in Africa south of the Sahara and Ghana is no exception. Out of a total potential irrigated area of close to 2 million ha, less than 20,000 ha large-scale irrigation and less than 200,000 ha of small-scale irrigation have been developed; but the latter is only an estimate. To identify entry points for accelerating small-scale irrigation development in Ghana, a national and a regional stakeholder Net-Map workshop were held in Accra and Tamale, respectively. The workshops suggest that a wide variety of actors from government, the private sector, international organizations and funders, research organizations and NGOs are involved in the diffusion of small-scale irrigation technologies. However, there are important differences between actors perceived to be key at the national and at the regional levels in northern Ghana. At the national level, diffusion of small-scale irrigation technologies is considered to be largely influenced by the Ghana Irrigation Development Authority together with a series of private sector actors focused on importation, distribution and financing of technologies. Farmers are considered to have no influence over the diffusion of small-scale irrigation, suggesting that small-scale irrigation is largely considered a supply-driven process. In northern Ghana, on the other hand, farmers are considered to be key influencers, although participants noted that much of this was potential influence, together with a larger and more diversified set of government stakeholders that are seen as regulators and possibly gatekeepers. For irrigation diffusion to successfully move from importation to distribution to benefiting smallholder farmers, all of these actors have to come together to better understand farmers’ needs and challenges. A multi-stakeholder platform could help to increase communication between farmers as the ultimate beneficiaries of small-scale irrigation technologies and the many other actors interested in supporting this process.

Over the past decade, the aquaculture sector in Ghana has experienced tremendous growth—driven mainly by large-scale cage farms—but it has been unclear how the rural poor have shared in this growth. A research project has been initiated to help diagnose, design, and test interventions for better inclusion of the rural poor, women, and youth in the tilapia value chain. This report describes the baseline data on 603 small-scale tilapia farmers in Ghana. The data collected during two-hour face-to-face interviews during May–July 2019 are disaggregated by socioeconomic indicators, gender, and age group. Baseline data show that 9 percent of farm managers and owners were women, and an additional 9 percent of farms engaged women in some decision-making. Moreover, women contributed 16 percent of family labor and 5 percent of hired labor on farms. Youth represented 14 and 24 percent of owners and managers, respectively, but contributed 68 percent of the total family and hired labor on farms. A large majority of managers and owners had at least high school education, with a third of owners and a quarter of managers attaining at least a college degree. In Brong Ahafo and Ashanti regions especially, most farmers engaged mainly in crop farming and non-farm businesses as their main livelihood, with fish farming as a small contributor to overall household income and livelihood. Farmers in all regions had poor record-keeping and management practices and low compliance with sanitation, fish health, and food safety standards. A wide variety of input usage, management practices, and performance was observed among fish farms. As a result, the profitability of fish farms was also wide-ranging, between –12.00 and 46.00 cedi per m2, with an average of 8.82 cedi per m2. Despite wide variability in production and profits, the majority of farmers experienced positive profits. On average, a farmer received a profit of 2.4 cedi per kilogram of tilapia produced or a 27 percent profit margin. These encouraging figures indicate that farmers who adopt good aquaculture practices can achieve respectable profits.

How do cities build a social contract with their diverse constituencies and foster political trust among the urban poor? This study focuses on informal traders, who constitute a major source of food security and employment in urban Africa. Centered on Ghana’s three main cities, we analyze interviews with metropolitan policymakers and a survey of approximately 1,200 informal traders. The findings show that expectations about reciprocity and procedural justice play a key role in shaping the probability of trusting one’s local government. Lower levels of trust were associated with disappointment over the lack of benefits that accompany tax payments to local assemblies. Moreover, those who had experienced harassment by city authorities were less likely to trust their local government. The analysis demonstrates that political trust at the subnational level deserves greater empirical attention, especially as countries continue to deepen decentralization initiatives and cities strive to meet global development goals around inclusivity.

With the widespread growth of mobile phone coverage and adoption over the past decade, there has been considerable enthusiasm over the potential for information and communication technologies (ICTs) to provide a low-cost approach for farmers to overcome information constraints in agricultural initiatives. The commercial viability of ICTs relies on effective demand for these services. This paper assesses farmers’ willingness to pay (WTP) for a digital platform that provides nutrition-sensitive agricultural information in Ghana. Using the Becker-DeGroot-Marschak method to elicit WTP, we randomly vary the framing of the marketing messages for the service, as well as the gender of the person targeted, to examine the effects of framing and respondent gender on demand. We find that farmers are highly price sensitive, but most are willing to pay a low monthly price for the service. A nutrition-focused marketing message leads to higher WTP than an agriculture only message, and women have substantially lower WTP than men, with the latter difference driven by lower WTP for the service among women who report access to alternative sources of nutrition, health, and agriculture information.

Women’s empowerment is important to improve the status of women and achieve greater gender equity. It is also an important vehicle for achieving other development goals related to food security, nutrition, health, and economic growth. Increasingly, researchers seek ways to measure women’s empowerment, trace the pathways through which women’s empowerment is achieved, and provide guidance for policymakers and practitioners aiming to facilitate women’s empowerment through their interventions. This paper explores local perceptions of empowerment in the Upper East Region of Ghana in the context of a small-scale irrigation intervention targeted to men and women farmers. Using data collected through qualitative interviews and focus groups, the paper traces the linkages between small-scale irrigation and aspects of women’s empowerment, identified as important to men and women farmers themselves. The relationship between the components of empowerment and small-scale irrigation are placed within a larger context of social change underlying these relationships. Finally, this paper explores the ways that the introduction of modern technologies for small-scale irrigation may contribute to women’s empowerment.

Accurate understanding of peoples’ livelihoods activities is needed to inform effective policy. Existing evidence relies heavily on studies that use designated respondents to provide information about their household members, imposing significant costs on these respondents along with possible distortions in the data. In rural Ghana, we randomize the order that household members are asked about and estimate that response fatigue leads to undercounting of labor activities by 8% on average. Women are twice as impacted as men while youth are four times as impacted as older adults, distorting both within-household and population wide comparisons. These biases result from women and youth being listed systematically later in rosters and stronger effects of fatigue for them, conditional on roster position. The implications of our results extend to other topics of enquiry as well, wherever similar repetitive survey structures are deployed, such as birth records, plot-level inputs, and household consumption and expenditures.

Over the past decade, Ghana’s tilapia farming has experienced tremendous growth in production; however, much of the growth has been driven by large-scale cage farmers around Lake Volta. It remains unclear how this growth is and can be made more inclusive of poor and young women and men. This study was conducted to analyze different inclusive business models along the fish seed value chain that can potentially be implemented in Ghana. Based on literature review, field interviews, analysis of survey data, and stakeholder workshops, this study develops four business model prototypes for seed multiplication and distribution to increase farmers’ access to and use of quality tilapia seed: (1) Nursery , which buy fish fry from a reliable hatchery, transport them to locations near other farmers, and grow it to a larger size; (2) Local feed mill, with pelleting machine and technical knowledge to advise on feed formulation; (3) Agents, technical experts who supply fingerlings, handle transport and marketing, and provide technical advice; and (4) Local hatchery, which obtains brood stock from a reliable source, produces local fingerlings to sell to nearby farmers, and provides technical support. Initial ex ante financial and profitability analyses were undertaken and will be refined according to the actual context in the particular district where the sensitization and pilot-testing will take place. These business models have the potential not only to increase farmers’ access to and use of quality tilapia seed but also to provide livelihood and income generation along the fish seed value chain.

We study the validity of experimental methods designed to measure preferences for intra-household resource control among spouses in Ghana and Uganda. We implement two incentivized tasks; (1) a game that measures willingness to pay to control resources, and (2) private and joint dictator games that measure preferences for resource allocation and the extent to which those preferences are reflected in joint decisions. Behavior in the two tasks is correlated, suggesting that they describe similar underlying latent variables. In Uganda the experimental measures are robustly correlated with a range of household survey measures of resource control and women’s empowerment and suggest that simple private dictator games may be as informative as more sophisticated tasks. In Ghana, the experimental measures are not predictive of survey indicators, suggesting that context may be an important element of whether experimental measures are informative.

Globally, food system transformation is characterized by the increasing importance of food safety and quality standards for consumers. This trend is challenging for the food processing sector in Ghana, which is dominated by micro and small firms. This study investigates the factors influencing the adoption of food safety practices and the effect of such adoption on the profitability of nationally representative food processing firms in Ghana using instrumental variable approach and matching techniques. The study uses nationally representative data for 511 food processing firms. The data show few food processing firms (20 percent) have adopted food safety practices. Wide diversity of firms was observed, and firm size, firm age, registrations, trainings, processing activities, types of buyers, and number of distinct products explain the differing firm adoption of food safety practices. We also find that adopters of food safety practices earn more per month than do nonadopting firms, implying the presence of economic incentive to adopt food safety practices. Support in terms of food safety awareness and training to food processing firms can help improve adoption of food safety practices.

Land provides the basis for food production and is an indispensable input for economic livelihoods in rural areas. Landownership is strongly associated with social and economic power, not only across communities and households, but also within households. The link between landownership and women’s empowerment has been relatively well documented in general, but not specifically in relation to agriculture. This paper aims to fill this gap by analyzing how ownership of land is associated with agency and achievements in agriculture among female and male farmers in northern Ghana, a region transitioning from customary land tenure without individual ownership rights towards a more individualized and market-based tenure system. We use a recursive bivariate probit model and focus on eight different indicators in four distinct domains: decisions on agricultural cultivation, decisions on farm income, agricultural association membership, and time allocation. Our empirical estimates indicate that landownership is positively correlated with men’s and women’s agency in agriculture, namely in decisions on agricultural cultivation and membership in agricultural association. Yet, we also find that the gender gaps in participation in cultivation decisions, the use of agricultural earnings, and in agricultural workload continue to persist among those who own land. While the results underscore the importance of land as a resource that can enhance women’s agency, they also point out that policies aiming to solely advance land rights may not be sufficient to eradicate or even reduce gender inequality in agriculture.

Growth in Ghana during the last decade has not translated into meaningful benefits for rural households who experienced an increase in poverty in recent years. This reflects, among other factors, the relatively weak performance of the agricultural sector and its general lack of competitiveness. The government has identified agriculture as the backbone of its development strategy and is committed to address the numerous challenges faced by the sector. However, it is likely to encounter fiscal constraints in a postdevelopment assistance era. It is therefore crucial to understand the trade-offs associated with alternative spending strategies. In this study we develop an economywide modeling framework for analyzing returns to public spending in support of agriculture. The model is used to evaluate the effect of compositional shifts in spending given marginal returns to different areas of investment. Our analysis focuses especially on extension services and input subsidies as two important components of the government’s agricultural development strategy. The objective of the study is to advise policymakers on which spending strategy is the most likely to contribute to government’s development goals, such as poverty reduction or economic growth. We find that a doubling of the share of agriculture in total public budget would accelerate agricultural growth to somewhere between 7.6% and 8.6% against the business-as-usual scenario of about 3.5%. The level of growth achieved depends on the types of policies that are favored. In the examples presented here, we show that an input subsidy-oriented spending strategy may yield significant benefits in the short run (1–5 years), and especially in an expansionary fiscal environment, but investments in effective extensive services are more sustainable and rewarding in the medium- to longer-run (6–10 years), especially when public resources are more constrained. These results demonstrate why short-term political goals might result in policy choices that are suboptimal from a longer-term development perspective.

Weather shocks and other shocks affecting the economy of farm households often trigger a cascade of coping mechanisms, from reducing food consumption to selling assets, with potentially lasting consequences on child development. In polygynous households (in which a man is married to several women), the factors that may aggravate or mitigate the impacts of such adverse events are still poorly understood. In particular, little is known about the complex mechanisms through which women’s empowerment may affect the allocation of household resources in the presence of more than one female decision-maker. Where polygyny is associated with discriminatory social norms, co-wives may have limited bargaining power, which may translate into poorer outcomes for their children. While competition between co-wives may generate inefficiencies in the allocation of household resources, cooperation in the domains of agricultural production or domestic labor may lead to economies of scale and facilitate informal risk sharing. The rank of each co-wife may also have a strong influence on the welfare of her own children, relative to other children. Using the Feed the Future Ghana Population Survey data, I investigate the relationship between polygyny and children’s nutrition, and how it may be mediated through women’s bargaining power. Using the age of each co-wife as a proxy for rank, I also study how the senior-wife status of a mother may influence her children’s nutrition outcomes.

We analyze the linkages between irrigation and nutrition using data from irrigators and non-irrigators in Northern Ghana. The results show that (i) there is a modest difference in the overall household dietary diversity score between irrigators and non-irrigators, (ii) there are significant differences in the consumption of animal source foods between irrigators and non-irrigators, (iii) there are significant differences in the consumption of fruits and vegetables as well as sugar and honey between irrigators and non-irrigators, and (iv) the sources of food consumption differ between irrigators and non-irrigators. The analysis shows strong association between households’ nutritional status and their access to irrigation, with evidences suggesting that the irrigation-nutrition linkages play out both through the income and production pathways in Northern Ghana.

Many rural development programs aim at improving women’s economic empowerment in agriculture, but as rural income continues to diversify, women may prefer investing in nonfarm activities. In a framed field experiment with 1,527 men and women in Ghana, we elicit preferences for investments in crop farming versus other business activities. We analyze whether gender differences in preferences for non-farm diversification, if any, can be ascribed to differential access to physical and human capital, and to what extent a gender gap is explained by differences in socio-economic characteristics, skills, perceptions and norms. Despite strong beliefs that men and women are more skilled in crop farming and non-farm businesses, respectively, many respondents invest in both farm and non-farm activities and we find only a small gender gap in revealed preferences for non-farm diversification. This gap can be largely explained by gender stereotyping around perceived skills. Increasing access to physical and human capital does not significantly affect preferences. We conclude that both men and women reveal a strong preference for diversified investments, which needs to be reflected in programs and policies aiming to improve women’s economic empowerment.

Food safety hazards threaten the health and market access of smallholder farming households. Smallholders face a number of barriers to improving food safety and quality, including low awareness, high input costs, and the failure of premium prices to pass through to producers. In this paper we examine how lifting these barriers affects Ghanaian groundnut farmers’ adoption of low-tech, low-cost post-harvest practices that reduce aflatoxin contamination. We conduct a randomized controlled trial in northern Ghana over the course of two seasons to test three interventions: (1) training on aflatoxin and its prevention, (2) distribution of free drying sheets, and (3) a price premium for groundnuts that comply with local aflatoxin regulations. In the first year we test for effects on post-harvest practices and aflatoxin levels, and in the second we test for effects on aflatoxin levels only. We find that training farmers substantially improves post-harvest practices. Drying sheet distribution and to a lesser extent the premium price lead to further improvements. We find substantial corresponding decreases in aflatoxin levels from drying sheet provision in the study region where background aflatoxin levels were highest. Beyond regional differences, benefits are higher for households with higher aflatoxin at baseline, more members, and young children. The estimated impacts of the price premium intervention are of similar magnitude, but not statistically significant.

The frequency of natural disasters, especially storms and floods, has been increasing globally over the last several decades. Developing countries are especially vulnerable to such disasters but are often the least capable of coping with the associated impacts because of their limited adaptive capacity. Despite the increased interest in strengthening institutional capacity, it remains a challenge for many developing countries. Institutional capacity for disaster management and risk reduction can be built through various mechanisms. One key approach is via the agriculture sector, where climate-resilient agriculture has become an effective tool for adapting to climate change and developing resilience in the long run – resulting in increased capacity for disaster management and risk reduction at the system, institutional, and individual levels. This paper presents the experiences of four countries, which we have evaluated to develop an institutional strengthening framework.

This paper examines the prospects for import substitution in West Africa by analyzing the preferences of urban consumers for food product attributes. We use market surveys, choice experiments, and experimental auctions to assess price and quality competitiveness of locally-produced chicken, rice, and tilapia in Accra, Ghana. For the price analysis, we compare market prices of imported and local counterparts, and we compare the local costs of production to production costs in major exporting countries. For the quality analysis, we compare consumer perceptions and demand for quality attributes of local versus imported products using data from field experiments with 1,322 consumers. Our findings suggest that among the three products, rice has the lowest prospects for import substitution, due to supply-and demand-side constraints to local competitiveness. For rice, consumers prefer imported products, they perceive imports as having better quality than local products, and they are willing to pay a premium for imports. For chicken, consumers have a strong preference for local products, but the potential for expanding chicken production can only be met if production and processing costs can be reduced significantly to boost price competitiveness. For tilapia, a high preference for freshness provides a natural barrier to import entry, and the comparative advantage of local production can be enhanced by making continuous improvements in seed and extension systems, industry coordination, certification, and regulation.

Consumer demand for food safety is likely to be an important driver of public policies and industry-led efforts to reduce information asymmetry on food attributes and improved food safety. This paper examines the attribute demand for chicken meat and tilapia among 803 shoppers in Accra, Ghana. Freshness is the main attribute demanded by the overwhelming majority of shoppers, followed by food safety, price, taste and size. Consumers are willing to pay price premiums for food safety certifications, i.e., those certified according to Hazard Analysis and Critical Control Point (HACCP) principles or certified as free of antibiotic residue. However, the price premium shoppers are willing to pay for improved food safety vary by shoppers type. A third of tilapia shoppers and half of chicken meat shoppers are classified as food safety conscious shoppers and willing to pay a 10 to 12 percent higher price than noncertified products. In comparison, only a tenth of shoppers are considered to be price conscious and willing to pay a small premium (< 1 percent) for certified safe foods. We also tested an information treatment on the negative health implications of food contamination and its effect on shoppers’ decisions. The information treatment randomly assigned to shoppers was a significant predictor of food safety attribute demand for chicken meat but not for tilapia, which may be linked to greater awareness of and concern about antibiotic misuse in poultry production. Our findings generally point to a concern about food safety and a strong demand and willingness among consumers to pay premiums for certified safe foods, thus providing support for public- or industry-led schemes to provide food safety information to consumers.

Despite the urbanization and gradual rise of medium-to-large scale farming sector, smallholders without substantial mechanization remain central to agriculture in countries like Ghana. Significant knowledge gaps exist on the adoptions of agricultural mechanization among smallholders for whom the scope for exploiting complementarity with land is limited. We test the hypotheses that high-yielding technologies, which potentially raise total factor productivity and also returns to more intensive farm power use, are important drivers of adoptions of agricultural mechanization among smallholders. Using the three rounds of repeated crosssectional, nationally representative data (Ghana Living Standard Surveys 2006, 2013, 2017), as well as unique tractor-use data in Ghana, and multi-dimensional indicators of agroclimatic similarity with plant- reeding locations, this paper shows that the adoption of rented agricultural equipment and tractors in Ghana has been induced by high-yielding production systems that have concentrated in areas that are agroclimatically similar to plant-breeding locations. These effects hold for mechanization adoptions at both extensive margins (whether to adopt or not) and intensive margins (how much to adopt). These linkages have strengthened between 2006 and 2010s, partly due to improved efficiency in supply-side factors of mechanization.

Ghana is one of a few African countries where agricultural mechanization has recently undergone rapid development. Except for places in the forest zone where stumps are still an issue in fields, tractors used for plowing and maize shelling have been widely adopted even among small farmers. Medium- and large-scale farmers who own tractors provide the majority of mechanization services. Recognizing this fundamental fact is important for designing any effective mechanization policy, which should aim at the entire service market instead of targeting a selected group of service providers as beneficiaries. Tractor owners and operators are often discouraged from traveling long distances to plow only a few acres for individual small farmers, which becomes a considerable barrier for smallholders to access tractor services on time. This requires the government consider mechanisms to improve coordination among small farmers and to encourage Farmer Based Organizations (FBOs) to facilitate such coordination. The use of harrowing or second-plowing has been shown as a productivity-enhancing farming practice but it is currently under-demanded by farmers. A pilot program to address the coordination failures and to nudge small farmers to adopt harrowing services together can be considered.

In 2009, Ghana began pursuing the devolution of functions and responsibilities from the central government to the country’s 216 Metropolitan, Municipal, and District Assemblies (MMDAs). Agriculture was among one of the first sectors to be devolved, a process that became effective in 2012. This paper analyzes how this transition has proceeded, with a focus on the implications for agricultural civil servants within the MMDAs, accountability to citizens, and agricultural expenditures. Empirically, the paper draws on a survey of 960 rural households, 80 District Directors of Agriculture (DDAs), district level budget data from 2012 to 2016, and semi-structured interviews with a range of national and local government stakeholders.

This paper uses data from a sample of 679 food processing firms in Ghana to estimate changes in employment by the food processing sector from 2014 to 2017, to analyze the determinants of firm exit during the same period, and to analyze the determinants of firm growth from the firm’s establishment up to 2017. In modeling the determinants of firm growth, the focus is on the effects of formal status as a food processing firm, which is defined in this paper as registration as a business for tax purposes and registration with the national food regulator, the Food and Drugs Authority (FDA).

As climate change makes precipitation shocks more common, policymakers are becoming increasingly interested in protecting food systems and nutrition outcomes from the damaging effects of droughts and floods (Wheeler and von Braun, 2013). Increasing the resilience of nutrition and food security outcomes is especially critical throughout agrarian parts of the developing world, where human subsistence and well-being are directly affected by local rainfall. In this study, we use data from Feed the Future datasets from Ghana, Zambia, and Bangladesh to examine the impact of precipitation extremes on food security as well as the role of natural land cover and women’s empowerment in creating resilience. We first model the effects of extreme rainfall on indicators of nutrition and food security, and then examine whether women’s empowerment and environmental land cover types can dampen the effects of rainfall shocks on these food security and nutrition outcomes. Our results find that there is a strong association between extreme precipitation and household hunger. Further, they suggest that in certain contexts land cover types providing ecosystem services can reduce household hunger scores, that empowering women can mitigate the effects of precipitation shocks, and that there may be an interactive effect between ecosystem service availability and women’s empowerment.

This paper uses an innovative research process to quantify the potential impacts of releasing and adopting insect-resistant (IR) cowpea and nitrogen-use efficient (NUE) rice in Ghana using an economic surplus partial equilibrium model. The premise of the research process was to build national capacity to produce timely and robust estimates, based on secondary data and qualified experts’ informed opinions, collected in country. Ghana’s stakeholders selected the two genetically modified (GM) technologies discussed here based on their assessment of these GM products’ regulatory advancement and their economic and political importance. Using assumptions regarding the expected changes from the adoption and commercialization of these crops, collected from national and international crop and technology experts, the authors estimate that the benefits of adopting IR cowpea are between US$5.5 million and US$125.3 million, and between US$1.9 million and US$153 million for NUE rice. The analysis also shows how a five-year regulatory delay may erode these benefits, reducing them by between 29 and 39 percent for IR cowpea and between 28 and 57 percent for NUE rice. Additionally, the authors make preliminary estimates of sex-disaggregated benefits and calculate the unequal distribution of benefits between female and male producers and consumers owing to gender disparities in production and consumption. The welfare estimations are based on an economic surplus model that were estimated using the DREAM software. Although this partial equilibrium model has limitations regarding market-clearing assumptions and is specific to a product, it is a data-parsimonious method that can produce results in a short time frame, which might better suit policymakers’ and decision makers’ demands for rapid estimations.

There is very limited experimental evidence of the impact of large-scale, government-led school meals programs on child educational achievements in Sub-Saharan Africa. We address this gap by reporting treatment effects from a nationwide randomized trial of the Government of Ghana’s school feeding program (GSFP) on children’s math and literacy, cognition (problem-solving ability and working memory), and composite scores of overall attainments. Based on the government’s plans to re-target and scale up the GSFP, food insecure schools and related communities across the country were randomly assigned to school feeding. After two years of implementation, program availability led to moderate increases in test scores for the average pupil in school catchment areas, ranging between 0.12 and 0.16 standard deviations. Analysis focusing on per-protocol population subgroups unveiled substantial heterogeneity: school feeding led to remarkable learning and cognitive gains for girls, poorest children, and children from the northern regions. Program effects were at least twice as large as for the average child. Increases in enrolment, grade attainment, and shifts in time use toward schooling time constituted potential mechanisms for impact. We conclude the program combined social protection with equitable human capital accumulation, thus contributing to the imperative of “learning for all” set in the Sustainable Development Goals.

In this paper we empirically analyse the impact of mothers’ non-farm entrepreneurship on child secondary school enrollment in rural Ghana. We use nationally representative quantitative data from the sixth round of the Ghana Living Standard Survey (GLSS) and qualitative data from focus group discussions throughout rural Ghana. We apply instrumental variable estimation techniques with instruments that pass weak and overidentification tests. We test interaction effects between mothers’ non-farm entrepreneurship and other important determinants of child schooling. We use qualitative data to support our quantitative findings.

Despite improvements to the implementation regime of Ghana’s fertilizer subsidy program, this paper shows that considerable challenges remain in ensuring that the subsidy is targeted to farmers who need fertilizer the most. Currently, larger-scale and wealthier farmers are the main beneficiaries of subsidized fertilizer even though the stated goal is to target smallholder farmers with fertilizer subsidies. The experience of other African countries suggests that the effectiveness of fertilizer subsidies can improve with effective targeting of resource-poor smallholders. However, targeting smallholder farmers entails significant transaction costs and may even be infeasible in some cases. Faced with such challenges, Ghanaian policy makers must ponder the question of how to improve the targeting of input subsidy programs in the country. Further research is needed to identify more cost-effective approaches for achieving the goal of targeting.

The past decade has seen increased attention to measuring women’s empowerment and autonomy, motivated by the goal of identifying promising programs and policies for reducing gender inequalities. One of the most common quantitative indicators of women’s empowerment is the self-reported ability to participate in household decision making over important matters. Despite the widespread use of such indicators in the literature, uncertainty exists over how to construct valid indicators of empowerment based on questions about decision making. In particular, it is unclear how indicative joint decision making is of individual decision-making power and to what extent joint decision making reflects a consistent understanding of decision-making power within households. We utilize data from women and men in Bangladesh and Ghana to investigate whether respondents who report sole decision making in a particular domain tend to experience stronger or weaker feelings of autonomous motivation—measured using a Relative Autonomy Index—than those who report joint decision making. We find systematic differences between men and women in the association between feelings of autonomous motivation and decisionmaking outcomes. In addition, results vary by the domain of decision making and by whether or not there is a shared understanding of decision-making power within households. These findings suggest that in order to accurately measure empowerment, further innovation in the specificity as well as the sensitivity of indicators is needed.

This paper analyzes the impacts of adopting restrictive import policies for chicken meat in Ghana, which would be like the policies adopted in Nigeria. A prohibitive tariff stimulates domestic chicken meat production but also imposes significant costs on consumers and encourages illicit trade. However, a substantial poultry industry, producing mostly eggs, will exist independent of the border policy applied to chicken meat, due to the natural protection offered to local producers in the egg subsector. A subsector analysis of an egg production cluster in Ghana highlights the importance of trade links with other West African countries in developing the egg subsector. A focus on feed efficiency, through a mix of domestic production and imports, would benefit the layer industry, provide reasonable indications of prospects for globally competitive chicken meat production, and benefit other industries dependent on competitive feed, notably aquaculture.

Understanding how various entities in a policy system at the national level can contribute to improved use of evidence in policy making. Yet little research has focused in developing countries on how various actors and players in a policy system work together to achieve a set of policy goals. In this paper, we study the factors contributing to the effectiveness of a policy system. The process of policy design, adoption, implementation, and refinement requires an effective policy system as well as a capacitated and supportive institutional structure. External actors both through technical and financial assistance often support policy systems in developing countries. Poor coordination and harmonization of such assistance among various actors and players within the country can often result in undermining the very policy systems they try to strengthen. This is typical in the African agricultural development process. In this paper, we develop a conceptual framework for understanding the policy and institutional architecture of food and agriculture policy system and for improving the coordination and harmonization of the roles of policy actors and players. Applying the framework to Ghana, we map and analyze the organizational contributions of various actors and their functional characteristics. We show how such analysis can aid various policy actors in setting priorities and strategies for increasing their capacity and the effectiveness of their roles. Finally, we draw lessons for strengthening the food policy systems in developing countries through effective coordination among local and external actors.

The rise in returns-to-scale (RTS) has often been an integral part of the agricultural transformation process around the world. Although tractor ownership is often associated with greater RTS in agriculture, whether tractor ownership actually causes such increase in RTS has not been formally tested in the literature. We provide evidence that partly bridges this knowledge gap, using unique survey data of tractor-owning farm households in Ghana. We find that owning tractors significantly increases RTS in maize production from the households’ largest monocropped plot. Specifically, owning tractors raises RTS for farmers because they can till greater areas, even though returns from tilling more land remain relatively unaffected. The increase in RTS holds regardless of the values of tractors owned. These sets of evidence are obtained by addressing jointly the multiple sources of endogeneity of tractor ownership, tractor values, tillage intensity, and other inputs used, through combinations of inverse-probability weighing method, generalized method of moments method, and the mediation effects model with multiple mediators. The adoptions of mechanical technologies (tractors) and their ownerships are causing, rather than simply responding to, the rise in RTS in Ghanaian maize production.

This paper complements the gender and technology adoption literature by shifting attention to what happens after adoption of a technology. Understanding the expected benefits and costs of adoption from the perspective of women users can help explain the technology adoption rates that are observed and why technology adoption is often not sustained in the longer term. Drawing on qualitative data from Ethiopia, Ghana, and Tanzania, this paper develops a framework for examining the intrahousehold distribution of benefits from technology adoption, focusing on small-scale irrigation technologies. The framework contributes to the conceptual and empirical exploration of jointness in control over technology by men and women. It does this by identifying a series of decisions following technology adoption, and how these decisions affect how the technology is used, by whom, to whose benefit, and with what costs.

This study focuses on the feed milling industry, which serves as the link between maize and poultry, through a field assessment of feed millers in Ghana. The findings establish the importance of feed in the poultry value chain. In addition, they show how the sector has become more integrated with poultry production, especially on larger-scale poultry farms. Because maize accounts for 60 percent of poultry feed, its availability and price have important implications for the profitability and growth potential of feed and, therefore, for poultry production as well. We illustrate these linkages by means of a simple spatial market equilibrium model that ties together the three sectors of the poultry value chain: the primary inputs (maize and soybeans), intermediate inputs (feed), and final products (meat and eggs). This model also enables us to assess the future growth potential of the poultry industry given alternative policy-driven changes in productivity and the production capacities of all three sectors. The results show that for poultry meat, replacing imports with domestic production in the short term would be nearly impossible. For the egg industry, however, there is potential for Ghana to export to neighboring countries by reducing production costs through improvements in yellow maize production.

Urbanization has had a major impact on livelihoods in Ghana and throughout Africa as a whole. However, much research on urbanization has focused on effects occurring within cities, while there is insufficient understanding of its effects on rural areas. This paper examines the impact of urbanization—through a typology of districts—on rural livelihoods in Ghana. The country’s districts are classified into seven spatial groups according to the size of the largest city in each district in southern and northern Ghana. The paper does not address rural–urban migration but instead focuses on the livelihoods of rural households. In contrast to the extensive literature focusing on the effects of urbanization on individuals, we assess its impacts on individual rural households as a whole, with a particular focus on youth-headed households. Many rural households have shifted their primary employment from agriculture to nonagriculture, especially in the more urbanized South. In contrast, change in livelihood diversification within rural households with family members’ primary employment in both agriculture and nonagriculture appears much less rapid. Rural youth-headed households are significantly more associated with the transition away from agriculture than households headed by other adults, and such trends are stronger in locations closer to larger cities, particularly in the South. Although the nonagricultural economy is becoming increasingly important for rural households, contrary to expectations, the probit model analysis in this paper shows that agricultural production does not appear to be more intensified—in terms of modern input use—in the more urbanized South, and youth do not show greater agricultural technology adoption than other adults, indicating that the constraints against modern input adoption may be binding for all farmers, including youth and farmers in more urbanized locations. We also find that rural poverty rates are consistently lower among nonagricultural households, and the share of middle-class population is also disproportionally higher among rural nonagricultural households than agricultural households. While the probit analysis confirms the positive relationship between being a nonagricultural household and being nonpoor or becoming middle class after controlling for all other factors, education seems to play the biggest role. As rural youth become more educated and more households shift from agriculture to the rural nonfarm economy, a different range of technologies for agricultural intensification is necessary for agriculture to be attractive for youth. A territorial approach and related policies that integrate secondary cities and small towns with the rural economy deserve more attention such that the diversification of rural livelihoods can become a viable alternative or complement to rural–urban migration for youth.

Ghana has accepted the CAADP commitment to dedicate 10 percent of government spending to the agricultural sector. In a 2014 paper, Benin argues that Ghana falls short of that goal, and in a 2016 paper, Younger shows that despite the current fiscal crisis, there is fiscal space to meet the commitment. Benin estimates the rates of return to increased public expenditure on agriculture, finding that they are quite high, especially if the investments are made in the noncocoa sector. This paper uses Benin’s estimates to examine the poverty and inequality consequences of increasing public expenditure on agriculture. Key conclusions are that public expenditure on agriculture is surprisingly progressive, especially if spent in the grains subsector. This progressivity, combined with the high rate of return, means that public investment in agriculture may actually be more efficient at reducing poverty than LEAP, Ghana’s targeted conditional cash transfer program.

This paper describes how modern service providers have emerged in the African agricultural sector, a subject that has been vastly understudied. The paper looks at providers of modern rice mills, power tillers, combine harvesters, and production services at a highly productive rice irrigation scheme in Ghana. These service providers earn net profits that are greater than the profits they would likely achieve from simply expanding rice production without investing in respective machines, suggesting that higher returns primarily induce the emergence of these modern providers. Surpluses and experiences from their years of rice production are likely to have provided the primary finance and knowledge required for entry. The service providers emerged by exploiting both the economies of scale and the economies of scope, keeping rice production as the primary source of income, instead of specializing only in service provisions. Key policy implications are also discussed.

Ghana is again experiencing large and chronic fiscal deficits that many analysts attribute to a sharp increase in its the public-sector wage bill. This study uses macroeconomic and household survey data to examine public employment and public wages both historically and in comparison with private-sector wages. Although we do find a public-sector wage premium in the most recent data (for 2012/2013), it is not as large as one would expect from the macro data, totaling only 15 to 28 percent of the public-sector wage bill, or 2 to 3 percent of gross domestic product. That is far from enough to eliminate the government deficit. To make further reductions in the wage bill, policymakers must either make the normative case that public-sector workers should be paid less than private-sector workers with similar qualifications, something that will be difficult politically, or they must adjust the required skill levels of public-sector employees downward, something that may not make administrative sense. There is some low-hanging fruit in the public-sector wage bill, but not enough to resolve Ghana’s fiscal crisis.

Despite recent modifications, the Economic Partnership Agreement (EPA) between the European Union (EU) and West African (WA) countries is still being criticized for its potential detrimental effects on WA countries. This paper provides updated evidence on the impact of the EPA on these countries. A dynamic multicountry, multisector computable general equilibrium trade model with modeling of the dual-dual economy and with a consistent tariff aggregator is used to simulate a series of new scenarios that include updated information on the agreement. We also go beyond estimating macrolevel economic effects to analyze the impacts on poverty. The policy simulation results show that the implementation of the EPA between the EU and WA countries would have marginal but positive impacts on Burkina Faso and Côte d’Ivoire and negative impacts on Benin, Ghana, Nigeria, Senegal, and Togo. The impact on poverty indicators in Ghana and Nigeria would be marginal. From the perspective of WA countries, this study supports the view that recent EU concessions are not sufficient and that domestic fiscal reforms are needed in WA countries themselves.

This study contributes to the literature by examining the agriculture‒nutrition linkage using data from northern Ghana. Specifically, we assess the relative importance of productivity and production diversity in improving household dietary diversity, while at the same time assessing the role of market access. We find that both on-farm production diversity and productivity positively affect household dietary diversity. In addition, the effect of production diversity gets stronger the longer the travel time to the nearest daily market.

This paper assesses whether fertilizer subsidy programs can be better targeted to resource-poor farmers using the case of Ghana and proxy means test approaches. Past fertilizer subsidy programs in the country have not been particularly targeted to the poor, even as targeting poor and smallholder farmers has become key in the program implementation guidelines. As a result, many poor farmers have not benefited from past programs. Our results show that targeting approaches based on proxy means tests that use the correlates of poverty to select beneficiary farmers can potentially improve the poverty outreach and costeffectiveness of Ghana’s fertilizer subsidy programs. Therefore, we propose that the proxy means test approach should be considered for implementing Ghana’s fertilizer subsidy programs, first in a pilot project involving a few communities, and later, if found successful, in a full-scale program.

At a time when donors and governments are increasing efforts to mainstream gender in agriculture, it is critical to revisit long-standing wisdom about gender inequalities in agriculture to be able to more efficiently design and evaluate policy interventions. Many stylized facts about women in agriculture have been repeated for decades. Did nothing really change? Is some of this conventional wisdom simply maintained over time, or has it always been inaccurate? We use longitudinal data from Ghana to assess some of the facts and to evaluate whether gender patterns have changed over time. We focus on five main themes: land, cropping patterns, market participation, agricultural inputs, and employment. We add to the literature by showing new facts and evidence from more than 20 years. Results are varied and highlight the difficulty of making general statements about gender in agriculture.

The focus in this paper is on two relatively large maize-based contract farming (CF) schemes with fixed input packages (Masara and Akate) and a number of smaller and more flexible CF schemes in a remote region in Ghana (Upper West). Results show that these schemes led to improved technology adoption and yield increases. In addition, a subset of maize farmers with high yield improvements due to CF participation had high gross margins. However, on average, yields were not high enough to compensate for higher input requirements and cost of capital. On average, households harvest 29–30 bags (100 kg each), or 2.9–3.0 metric tons, of maize per hectare, and the required repayment for fertilizer, seed, herbicide, and materials provided under the average CF scheme is 21–25 bags (50 kg each) per acre, or 2.6–3.0 tons per hectare, which leaves almost none for home consumption or for sale. Despite higher yields, the costs to produce 1 ton of maize under CF schemes remain high on average—higher than on maize farms without CF schemes, more than twice that of several countries in Africa, and more than seven times higher than that of major maize-exporting countries (the United States, Brazil, and Argentina). Sustainability of these CF schemes will depend on, from the firms’ perspective, minimizing the costs to run and monitor them, and from the farmers’ perspective, developing and promoting much-improved varieties and technologies that may lead to a jump in yields and gross margins to compensate for the high cost of credit.

This paper uses Ghana as a case study to illustrate the extent to which Chinese manufacturing firms are driving manufacturing in an African country. Through a combination of desktop and field research, the author finds that the total number of Chinese manufacturing investments in Ghana indeed increased during past decade, but quite a few projects have been abandoned or not implemented because of the unfavorable investment environment. Small and large manufacturing projects can be found in different sectors, such as plastics, steel, pharmaceuticals, and others. All of the manufacturing investments target local or regional markets, either taking advantage of local raw materials or seeing opportunities in a market with little competition. Transitioning from trading to manufacturing investment and clustering are identified as the main patterns by which Chinese investors establish themselves in Ghana. Chinese firms source simple raw materials from local suppliers but import industrial supplies from abroad. Learning from Chinese business models, a few local businessmen have started their own manufacturing projects, mostly in the plastics recycling sector, but a lack of capital appears to keep some local players from moving up the value chain. Ghana’s weak economy itself is limiting technology transfer and local linkages between Chinese firms and Ghanaians.

In recent decades, Ghana has experienced high economic growth and transformation, which contributed to the nation achieving the Millennium Development Goal targets on reducing extreme poverty and hunger. Against this background and in view of achieving the food and nutrition security targets of the Sustainable Development Goals, Ghana started a process of reviewing its food security and nutrition strategies and policies, including the overarching Zero Hunger Strategy. This discussion paper aims to contribute to this process by providing an update on the state of Ghana’s food and nutrition security. In addition to providing an overview of long-term historical trends at the national level, this analysis provides an overview of regional patterns of food and nutrition insecurity and recent changes across Ghana’s 10 administrative regions. Finally, the analysis identifies regional “hot spots” of food and nutrition insecurity. This paper confirms that Ghana has achieved substantial improvements in food and nutrition security overall, especially over the past decade. Nationwide, progress has been made in improving households’ economic access to food by reducing poverty and extreme poverty and in reducing chronic and acute child undernutrition. However, progress in reducing micronutrient malnutrition—particularly anemia and especially among young children—has been more modest. Across Ghana, large rural-urban gaps and regional differences—mainly between the north and the south—remain for most dimensions of food and nutrition security. In addition, Ghana is increasingly facing new nutrition-related public health problems that result from overnutrition and diets too rich in calories. Overweight and obesity among adults are rising rapidly in both urban and rural areas, leading to an increase in the risk of noncommunicable diseases. The rising double burden of malnutrition—that is, the coexistence of overnutrition and undernutrition, including micronutrient deficiencies—constitutes a challenge to public health and social protection policy. These new nutritional realities may make some existing food and nutrition security policies obsolete or even detrimental to nutrition security.

Contract farming (CF) is attractive as a possible private-sector-led strategy for improving smallholder farmers’ welfare. Yet many CF schemes suffer from high turnover of participating farmers and struggle to survive. So far, the dynamics of CF participation have remained largely unexplored. We employ duration analysis to examine factors affecting entry into and exit from different maize CF schemes in northern Ghana, focusing specifically on the impact of development projects on CF entry and exit. We find that agricultural development projects reduce the likelihood of scheme entry and increase the likelihood of exit. Our findings confirm concerns that, if interventions are not planned in accordance with relevant private-sector actors, private-sector initiatives can be hindered by competing development projects.

Tenure security is believed to be critical in spurring agricultural investment and productivity. Yet what improves or impedes tenure security is still poorly understood. Using household- and plot-level data from Ghana, this study analyzes the main factors associated with farmers’ perceived tenure security. Individually, farmers perceive greater tenure security on plots acquired via purchase or inheritance than on land allocated by traditional authorities. Collectively, however, perceived tenure security lessens in communities with more active land markets and economic vibrancy. Migrant households and women in polygamous households feel less secure about their tenure, while farmers with political connections are more confident about their tenure security.

This paper characterizes the transition from small-scale farming and the drivers of farm size growth among medium- and large-scale farmers in Ghana. The research was designed to better understand the dynamics of change in Ghana’s farm structure and contribute to the debate on whether Africa should pursue a smallholder-based or large-scale oriented agricultural development strategy. The results suggest a rising number of medium-scale farmers and a declining number of smallholder farmers in the country, a pattern that is consistent with a changing farm structure in the country’s agricultural sector. More important, findings show that the rise to medium- and large-scale farming is significantly associated with successful transition of small-scale farmers rather than entry of medium or large farms into agriculture, reflecting small-scale farmers successfully breaking through the barriers of subsistence agriculture into more commercialized production systems. The findings in this paper also suggest that some of the factors thought to be important for change in farm structure are no obstacle to farm size growth, even though they may foster transition. Notably, the results here diverge from the patterns observed in Zambia and Kenya, which indicate that the emergent farmers came mostly from the urban elite. Unfortunately, past and current policy discussions have not featured these emergent farmers sufficiently in the quest to transform agriculture in Ghana. Government should capitalize on these emergent farmers who have a demonstrated ability to graduate productively as it strives to address challenges in the smallholder sector.

Ghana is in the midst of a severe but not unprecedented macroeconomic crisis. This paper helps to evaluate the government’s policy options by (1) explaining the crisis’ causes, and (2) comparing it to previous macroeconomic crises and the policies that corrected them. Two large shocks are to blame for the crisis: an increase in the fiscal deficit of about 6 percent of GDP and a reduction in hydroelectric production that has not been replaced with thermal generation. This latter is more difficult to quantify, but may be as large as 4 percent of GDP. While large, Ghana has recovered from similar shocks in the past, and with luck, should be able to do so now. But this will require reversal of the large increases in the public sector wage bill that drove much of the fiscal shock.

Improving women’s access to land is high on the agricultural policy agenda of both governmental and non-governmental agencies. Yet, the determinants and rationale of gendered access to land are not well understood. This paper argues that gender relations are more than the outcomes of negotiations within households. It explains the importance of social norms, perceptions, and formal and informal rules shaping access to land for male and female farmers at four levels: (1) the household/family, (2) the community, (3) the state, and (4) the market. The framework is applied to Ghana. Norms on household and family organization and on men’s and women’s responsibilities and capabilities play a key role in gendered allocation of resources. However, these norms and perceptions are dynamic and evolve jointly with the development of markets and changes in values of inputs such as labor and land. Theoretical models that represent the gendered distribution of assets as the result of intrahousehold bargaining should be revised, and extrahousehold factors should be included. From a policy perspective, laws that ensure gender equality in terms of inheritance and a more gender-equitable distribution of property upon divorce can play a key role in improving women’s property rights. Yet, their impact may be limited where customary rights dominate and social norms and rules continue to discriminate according to gender.

Ghana’s Fertilizer Subsidy Programme (GFSP) was initiated in 2008 in response to the global food and fuel price crisis. Although initially intended to be a temporary measure that became increasingly expensive as Ghana’s macroeconomy deteriorated, farmers, civil society organizations, and politicians began to expect the subsidy on an annual basis. This paper applies the kaleidoscope model for agricultur and food security policy change to the case of GFSP. In doing so, it uses a variety of analytical tools to highlight how many of the weak outcomes of GFSP can be attributed to the nature of the broader policy process that has surrounded GFSP as well as the underlying political and institutional context in which policy making occurs in Ghana. Based on semi-structured interviews conducted with knowledgeable stakeholders spanning the government, donor, civil society, and research communities, the paper identifies the bottlenecks that need to be addressed if the program is to be more effective in the future.

What are the political and institutional prerequisites for pursuing policies that contribute to structural transformation? This paper addresses this question by focusing on Ghana, which has achieved sustained economic growth in recent decades and is broadly lauded for its environment of political pluralism, respect for human rights, free and fair elections, and vocal civil society. Yet, despite these virtues, Ghana remains unable to achieve substantial structural transformation as identified as changes in economic productivity driven by value-added within sectors and shifts in the allocation of labor between sectors. This paper argues that Ghana is strongly democratic but plagued by weak state capacity, and these politico-institutional characteristics have shaped the economic policies pursued, including in the agricultural sector, and the resultant development trajectory. Specifically, three political economy factors have undermined Ghana’s ability to achieve substantive structural transformation since then. First, democracy has enabled a broader range of interest groups to permeate policymaking decisions, often resulting in policy backtracking and volatility as well as fiscal deficits around elections that, among other things, stifle credit access for domestic business through high interest rates. Secondly, public sector reforms were not pursued with the same vigor as macroeconomic reforms, meaning that the state has lacked the capacity typically necessary to identify winning industries or to actively facilitate the transition to higher value-added sectors. Thirdly, successive governments, regardless of party, have failed to actively invest in building strong, productive relationships with the private sector, which is a historical legacy of the strong distrust and alienation of the private sector that characterized previous government administrations.

The adoption of machinery in agricultural production in Africa south of the Sahara has been far behind the level of mechanization found in Asia and Latin America. However, recent survey data have revealed high levels of machinery use in localized areas of cereal production in northern Ghana. A survey conducted by the International Food Policy Research Institute, in partnership with the Savannah Agriculture Research Institute, found that in some areas more than 80 percent of farmers were using machinery for at least one operation. This paper considers the theoretical drivers of agricultural intensification, as outlined by Boserup, Pingali, and Binswanger, and the extent to which they are able to explain the spatial variation in machinery use found in northern Ghana. Population pressure, market access, and agroecological conditions are considered key drivers that cause farmers to find ways to increase productivity and adopt new technologies. Combining survey data with geospatial datasets, the empirical analysis finds that population growth and travel time to the local urban center explain a significant and large proportion of the variation in machinery use by farmers.

Using public expenditure and agricultural production data on Ghana from 1970 to 2012, this paper assesses the returns to public spending in the agricultural sector, taking into consideration expenditures on agriculture as a whole and then separately for expenditures in the cocoa versus the noncocoa subsectors. Production functions for the agricultural sector as a whole are estimated first, and then separately for the two subsectors, to obtain elasticities of land productivity with respect to total and sectorial agricultural expenditure. Different regression methods and related diagnostic tests are used to address potential endogeneity of agricultural expenditure, cross-subsector dependence of the production function error terms, and within-subsector serial correlation of the error terms. The estimated elasticities are then used to calculate the rate of return (ROR) to expenditures in the sector as a whole and within the two subsectors. The elasticities are estimated at 0.43 for total agricultural expenditure; 0.13 for aggregate expenditure in the noncocoa subsector; and 0.19–0.53 for expenditure in the cocoa sector, depending on aggregation or disaggregation of expenditure on the Ghana Cocoa Board and other industry costs. The ROR is estimated at 141–190 percent for total agricultural expenditure, 124 percent for expenditure in the noncocoa subsector, and 11–39 percent for expenditure in the cocoa subsector. The relatively higher ROR in the noncocoa subsector is mostly due to a much lower expenditure-to-productivity ratio. Implications are discussed for raising overall productivity of expenditure in the sector, as well as for further studies, such as obtaining actual time-series data on some of the production factors in the two subsectors and obtaining information on the quality of sectorial expenditures to model different time-lag effects of spending in the different subsectors.

This research was designed to understand better the patterns of agricultural intensification and transformation occurring in Africa South of the Sahara using the Ghanaian case. The paper examines changes in farming systems and the role of various endogenous and exogenous factors in driving the conversion of arable lands to agricultural uses in four villages within two agroecologically distinct zones of Ghana: the Guinea Savannah and Transition zones. Using essentially historical narratives and land-cover maps supplemented with quantitative data at regional levels, the research shows that farming has intensified in the villages, while farmers have increased their farm size in response to factors such as population growth, market access, and changing rural lifestyle. The overall trend suggests a gradual move toward intensification through increasing use of labor-saving technologies rather than land-saving inputs—a pattern that contrasts with Asia’s path to its Green Revolution. The findings in this paper provide evidence of the dynamism occurring in African farming systems; hence, they point toward a departure from stagnation narratives that have come to prevail in the debate on agricultural transformation and intensification in Africa South of the Sahara. We conclude that it is essential for future research to expand the scope of this work, while policies should focus on lessons that can be learned from these historical processes of genuine change.

This paper examines closely the constraints in productivity improvements and evaluates available rice technologies looking at the heterogeneity of irrigated and rainfed ecologies in 10 regions in Ghana. Employing yield response models, profitability analysis, and adoption models, results show various practices contribute to yield improvements in irrigated and rainfed systems including chemical fertilizer use, use of certified seed of improved varieties, transplanting, bunding, leveling, use of a sawah system, seed priming, and row planting. Evidence also shows that extension services on rice production are limited and that intensifying extension services can contribute to increases in rice yield.

The application of nitrogen (N) fertilizers is still insufficient across cropping systems in Africa south of the Sahara, while plant uptake of nitrogen is often inefficient and wasteful even when farmers apply fertilizers. This leaves sizable room for improving the productivity of crops and managing nutrient cycles. Fertilizer deep placement is a technology designed to enhance the efficiency of nutrient delivery to crops by placing granulated fertilizer directly in the root zone. Deep placement maximizes nutrient uptake by crops while using less fertilizer than surface broadcasting, and minimizes N losses due to runoff and ammonia volatilization. Urea deep placement (UDP) technology has been widely adopted in lowland paddy rice production systems in South Asia, especially in Bangladesh. There is a growing interest to scale up UDP adoption in West African countries, such as Ghana and Senegal, but a limited number of studies have been published from the region to support developing strategies. To contribute to the evidence-base, we use a grid-based cropping systems modeling framework, combined with analyses on the characterization of UDP and its geospatial targeting, and map the extent of biophysical suitability for UDP across regions in Ghana and Senegal and estimate potential yield increases under this technology.

For decades, policymakers and development practitioners have debated benefits and threats of property rights formalization and private versus customary tenure systems. This paper provides insights into the challenges in understanding and empirically analyzing the relationship between tenure systems and agricultural investment, and formulates policy advice that can support land tenure interventions. We focus on Ghana, based on extensive qualitative fieldwork and a review of empirical research and policy documents. Comparing research findings is challenging due to the use of different indicators, the varying contexts, and the diversity of investments. The interaction between land rights and investment make establishing causality extremely difficult. Setting policy priorities and strategies requires more and better insights into the diverse responses of different stakeholders and the tenure and cropping systems involved.

Access to and use of health services are concerns in poor countries. If implemented correctly, health insurance may help solve these concerns. Due to selection and omitted variable bias, however, it is difficult to determine whether joining an insurance scheme improves medical care–seeking behaviors. This paper uses representative data for the whole country of Ghana and an instrumental variable approach to estimate the causal impact on healthcare use of participating in Ghana’s National Health Insurance Scheme. Idiosyncratic variations in membership rules at the district level provide exogenous variation in enrollment. The instrument is the existence of nonstandard verification methods to allow enrollment of children. Using the 2008 Ghana Demographic and Health Survey and a census of all district insurance offices, this paper finds that insurance membership increases the probability of (1) seeking higher-quality (but no greater quantity of) maternal services and (2) parents’ becoming more active users of child curative care. Instrumental variable estimates are larger than ordinary least squares ones, indicating that “compliers” have much higher returns to being insured than the average participant. Results are robust to several validity checks; this paper shows that the instrument is indeed idiosyncratic and proves that government officials did not establish less-cumbersome membership rules in districts with worse initial indicators.

Value chain development is adopted widely as a private sector–led approach to agricultural development that can benefit smallholders. The objective of this research is to understand how development organizations are conceptualizing and developing agricultural value chains in Ghana to include smallholders. The study is based on case studies of five programs supported by various donors. A typology is employed to categorize the intervention. Common to all the programs are interventions to encourage the development of interlinked vertical contracts between smallholders and buyers and investments to improve the operations of actors downstream. The study explores issues related to expectations, scaling up of activities to reach a significant portion of the population, technology transfer, and participatory development of value chain strategies and identifies some indicators to examine the outcomes of value chain interventions.

There are concerns that increasing women’s engagement in agriculture could have a negative effect on nutrition because it limits the time available for nutrition-improving reproductive work. However, very few empirical studies have been able to analyze whether these concerns are well-founded. This paper examines whether an increase in women’s time in agriculture adversely affects maternal and child nutrition, and whether the lack of women’s time in reproductive work leads to poorer nutrition. Using data from Bangladesh, Cambodia, Ghana, Mozambique, and Nepal, we find that on the whole, in poor households, reductions in women’s reproductive work time are detrimental to nutrition, especially for children. In contrast, women’s and children’s nutrition in nonpoor households is less sensitive to reductions in time on reproductive work. Working long hours in agriculture reduces women’s dietary diversity score in Ghana and nonpoor women’s in Mozambique. However, for poor women and children in Mozambique, and children in Nepal, working in agriculture in fact increases dietary diversity. This suggests that agriculture as a source of food and income is particularly important for the poor. Our results illustrate that women’s time allocation and nutrition responses to agricultural interventions are likely to vary according to socioeconomic status and local context.

In this paper, we document an approach to capacity strengthening of parliamentarians in Ghana and attempt to gauge to what extent and under what conditions such investments could lead to better debates and informed policymaking to promote growth and poverty reduction. We traced a group of Ghanaian parliamentarians to draw lessons after their study and exposure visit to India. Exposure visits changed participants’ knowledge, outlook, and thinking toward agricultural policies.

This paper assesses whether tractor investment is a rational and profitable decision for farmers using firm investment theory and tractor owner survey data collected in 2013. Under erratic rainfalls, timeliness of farming operations is critical for farmers. Based on the hypothesis that owning a tractor and hiring tractor services are not necessarily perfect substitutes for farmers with relatively large farm sizes, this paper assesses whether mechanization services can be profitable for the private sector in Ghana. It particularly addresses whether farmer-to-farmer service provision is a viable alternative to current programs, which should be promoted by policymakers for scaling up agricultural mechanization in the country.

Houssou, Nazaire; Chapoto, Antony 2014
This study assesses whether the recent public and private efforts to improve farmers’ access to mechanical power in Ghana have had the intended effects on the country’s agricultural sector. Using panel survey data, this paper analyses the drivers of farm mechanization and its net impacts on cropland expansion and farming system intensification in northern Ghana. Several factors explain the use and use intensity of agricultural mechanization, including landholding size, total labor and fertilizer use per hectare, chemical use, and amount of land left fallow. More importantly, the results suggest that farm mechanization did have a positive impact on cropland expansion during the survey period. The results presented here support the existence of a labor substitution effect resulting from tractor use.

Groundnuts, which are widely consumed in West Africa, are prone to contamination by aflatoxin during production and storage. Although aflatoxin plays a role in many of the important health risks in developing countries, individuals and governments ignore the risks because their health effects are not immediate. In the developed world strong regulations remove contaminated kernels and their products from the food systems. The objective of this paper is to examine production and marketing practices, particularly grading methods, in Ghana’s groundnut value chain to obtain a clear understanding of the sources and levels of aflatoxin contamination in the crop and how such contamination can be sharply reduced.

This paper assesses the degree to which the L’Aquila Food Security Initiative (AFSI) has been implemented in Ghana within the framework of managing for development results (MfDR), and to evaluate progress in various outcomes, including economic governance, agricultural growth, poverty, and food and nutrition security. The MfDR approach, which has gained widespread support globally for obtaining results, is endorsed by the government of Ghana and reflected in the Ghana Aid Policy and Strategy.

Use of mechanization in African agriculture has returned strongly to the development agenda, particularly following the recent high food prices crisis. Many developing country governments—including Ghana, the case study of this paper—have resumed support for agricultural mechanization, typically in the form of providing subsidies for tractor purchase and establishment of private-sector-run agricultural mechanization service centers (AMSECs). The aim of this paper is to assess the impact of Ghana’s AMSEC program on various outcomes, using data from household surveys that were conducted with 270 farmers, some of them located in areas with the AMSEC program (treatment) and others located in areas without the program (control).

This paper was written to help bolster the case and present visual evidence demonstrating why it is important to seriously consider spatial soil fertility variability in Ghana and to promote area-specific fertilizer recommendations. Using geostatistical analysis of soil samples collected from farmer plots in three districts (Tamale Municipality, Savelugu-Nanton, and West Mamprusi in northern Ghana), the paper analyzes spatial variations in soil fertility. The results clearly show that there are variations in soil pH, organic matter content, and available phosphorous even at the community level, supporting the need for Ghana to seriously consider location-specific fertilizer recommendations.

This paper is part of four country case studies that take a detailed look at public expenditures in agriculture, and at how the data on expenditures are captured in government financial and budget accounts. The objective of these studies is to unpack the black box of public expenditure statistics reported in various cross-country datasets, and ultimately to enable the use of existing government accounts to identify levels and compositions of government agriculture expenditures, with better understanding of what these data are in fact accounting for.

Agriculture in African South of the Sahara (SSA) can be transformed if the right public support is provided at the initial stage, and it can sustain itself once the enabling environment is put in place. Successes are also specific to the location of projects. In Ghana, interesting insights are obtained from the successful Kpong Irrigation Project (KIP), contrasted with other major irrigation projects in the country. Through an exploratory review, we describe how a productive system evolved in KIP and how public support for critical aspects (accumulation of crop husbandry knowledge, selection and supply of profitable varieties, and mechanization of land preparation) might have created a productive environment that the private sector could enter and fill in the market for credit, processing, mechanization of harvesting, and other institutional voids that typically have constrained agricultural transformation in the rest of SSA.

Healthcare financing through social health insurance has become a very important tool in providing access to and utilization of health services in most developing countries such as Ghana. Ghana’s National Health Insurance Scheme (NHIS) is a promising tool for policymakers. Yet since its inception in 2003, few studies have assessed the scheme. This paper aims to explore the challenges facing the District Mutual Health Insurance Schemes (DMHISs), how these challenges have been managed over the years, and what can be done to improve the DMHIS operation. The scope of this study is to improve policies and guide support for Ghanaian DMHISs as well as to provide recommendations when implementing future NHISs in a developing-country context.

Using cross-sectional data on 630 maize farmers and 645 maize plots in Ghana, this paper provides empirical evidence on the responsiveness of maize yield to fertilizer use and use intensity and the economics of fertilizer use with or without subsidy. Similar to previous studies in Ghana and Africa south of the Sahara, the results show that there is a statistically significant maize yield response (that is, 1 kilogram of nitrogen leads to a yield increase of 22 kilograms per hectare).

The past decade has seen several African countries increasing their agricultural growth, a trend largely underpinned by increases in land area cultivated instead of productivity increases. Meanwhile, scholars debate whether Africa should pursue a strategy of large-scale or smallholder farms, paying little attention to a special group of smallholder farmers who have transitioned to become medium- and large-scale farmers. This study, therefore, begins to analyze this group of farmers, using qualitative data from in-depth interviews and focus group discussions in Ghana. We analyze their characteristics, ingredients of farm-size expansion, and commercialization.

McMillan, Margaret S.; Rodrik, Dani 2013
One of the earliest and most central insights from the literature on economic development is that development entails structural change. The countries that manage to pull out of poverty and get richer are those that are able to diversify away from agriculture and other traditional products. As labor and other resources move from agriculture into modern economic activities, overall productivity rises and incomes expand. The speed with which this transformation takes place is one of the key factors that differentiate successful countries from unsuccessful ones.

This brief focuses on growth patterns, structural change and agglomeration to assess the progress of economic transformation in Ghana. While Ghana has been seen as a successful story in Africa because of its sustainable growth performance and impressive poverty reduction over the last two decades, Ghana’s economy has actually exhibited less transformation than might be expected for a country that has recently achieved low‐middle income status.

The evidence of improved performance of the agricultural sector in Sub‐Saharan Africa (SSA) in recent years has indeed been quite striking. For the first time, agricultural gross domestic product (AgGDP) per capita has maintained a real growth rate of 2.4 percent per year, while real AgGDP growth rates have exceeded 6 percent, a growth rate last seen in the 1970s. Similarly, performance of the overall economy, with average growth rates of 5.3 percent per year, has also been remarkable. In this context, Ghana has shown one of the best performing agricultural sectors in the region with AgGDP growing at more than six percent per capita in recent years.

With renewed interest in technical change and productivity growth in the African agricultural sector, interest is growing in the lessons of Asia’s Green Revolution and in the implementation of input promotion and subsidies to promote agricultural growth. While there are several valid reasons for seeking a model for African agricultural productivity growth from the Asian Green Revolution, the abundance of natural resources in Africa compared to Asia means that the Asian lessons might have limited application across Africa.

The Comprehensive Africa Agriculture Development Programme (CAADP) was designed to promote the transformation of agriculture in SSA. Under this program, African countries have committed to seek development through agriculture led growth by targeting at least 6 percent growth and by allocating about 10 percent of government budget to the sector. In return, the donor community has implicitly committed to increase their support to agriculture using the CAADP mechanism, while at the same time coordinating their activities in this sector and aligning them with the CAADP priorities set by the African countries themselves.

Even though the intention of the government is to promote private sector-led mechanization, findings suggest that the AMSEC model is unlikely to be a profitable business model attractive to private investors even with the current level of subsidy. The low tractor utilization rate as a result of low operational scale is the most important constraint to the intertemporal profitability of tractor-hire services. The government can play an important role in facilitating the development of a tractor service market; however, the successful development of such a market depends on the incentive and innovation of the private sector, including farmers who want to own tractors as part of their business portfolio, traders who know how to bring in affordable tractors and expand the market, and manufacturers in exporting countries who want to seek a long-term potential market opportunity in Ghana and in other west African countries.

Use of agricultural input and farm support subsidies in Africa has returned strongly to the development agenda, particularly following the recent high food and input prices crisis. Many of the donors who opposed them in the past and subsequently put pressure to discontinue them due to their high cost and distortionary effect on the domestic economy are now providing aid in the form of farm support and agricultural subsidies. In Ghana, for example, the country of study in this paper, the government has since 2007 introduced four major subsidy and support programs on fertilizer, mechanization, block farms, and marketing. Therefore, a key question that arises is how the structure and policies of these current programs account for any of the general lessons and controversies experienced in the past and, in the process, achieve their intended goals in a more effective and economically viable manner.

Although the different roles of men and women in agriculture in different parts of Sub-Saharan Africa have been widely acknowledged, there have not been consistent efforts to collect data on these patterns. This paper presents a way of classifying gendered farm management systems and then describes pilots of four different approaches to collecting and georeferencing information on the dominant pattern in each area. Case studies from existing literature provided valuable insights but represent a time-consuming method, limited in spatial coverage and often leaving gaps because the original study authors did not report on all of the aspects of interest for a gendered farm management systems analysis. Expert consultations conducted in Ghana and Zambia allowed for dialogue among participants during map development, permitting them to explore nuances and dynamics. However, this technique may be restricted in scale to one country at a time, limiting cross-national comparison. An open online survey, or crowdsourcing, of the information tapped into a wide range of expertise, providing difficult-to-obtain widespread coverage, but had inconsistent data quality. Mapping of georeferenced information from nationally representative data could potentially provide widespread and relatively accurate data, but thus far the relevant underlying data have not been consistently included in large-scale surveys. Gender mapping offers an important step toward greater awareness of the diverse gender roles in agricultural farm management systems, but gaps remain between field reality and the understanding of gender relations in research, on the one hand, and between the researchers‘ understanding and what can be displayed on a map, on the other. Addressing these gaps requires developing a consensus on the key variables that characterize gendered farming systems, collecting these data systematically, and then linking the data to other spatial information for use in planning and prioritizing development interventions.

The cocoa sector in Ghana is one of few examples of an export commodity sector in an African country that has withstood the pressure to fully liberalize. Despite substantial government control over internal and external marketing via the Ghana Cocoa Board (COCOBOD), the current institutional arrangement is able to pass on a significant share of export prices to farmers, a key objective of the liberalization of commodity markets in Africa. As Ghana continues to capitalize on its recent discovery of off-shore oil reserves, the government and donors alike are concerned that the competitiveness of the cocoa sector may be threatened. The overall objective of this study is to examine the competitiveness of the cocoa sector by focusing on four aspects of the current set of institutions, including (1) the process of determining producer prices; (2) the outcomes of the introduction of private licensed buying companies; (3) COCOBOD’s role in maintain quality, and the costs and benefits of this process; and (4) trends in COCOBOD expenditure on the provision of various goods and services. The methodology adopted for this study is primarily that of an expenditure review.

A number of factors favor a collective strategy for African countries to build their reputation regarding improved governance and commitment to agriculture. These include negative spillover effects of poor governance (for example, obstacles to developing regional markets), improved bargaining power of African governments vis-à-vis the donor community, long-standing political efforts to build a positive African identity, and a donor interest in reducing transaction costs by interacting with African countries though regional organizations rather than individually. While realizing these potentials, the CAADP effort to build collective rather than individual reputation involves the classical free-rider problem of collective action: Countries may not honor their commitments after having received increased aid—a strategy that will harm all member countries since it undermines the collective reputation. Since CAADP involves a collective commitment by the donor community as well, donors face similar problems of collective action. They, too, may fail to honor their commitments or revert to individual rather than harmonized approaches to support African agriculture. The paper discusses the strategies that CAADP can use to overcome these collective action challenges.

In the context of the Ghanaian government’s objective of structural transformation with an emphasis on manufacturing, this paper provides a case study of economic transformation in Ghana, exploring patterns of growth, sectoral transformation, and agglomeration. We document and examine why, despite impressive growth and poverty reduction figures, Ghana’s economy has exhibited less transformation than might be expected for a country that has recently achieved middle-income status. Ghana’s reduced share of agriculture in the economy, unlike many successfully transformed countries in Asia and Latin America, has been filled by services, while manufacturing has stagnated and even declined. Likely causes include weak transformation of the agricultural sector and therefore little development of agroprocessing, the emergence of consumption cities and consumption-driven growth, upward pressure on the exchange rate, weak production linkages, and a poor environment for private-sector-led manufacturing.
