× There is growing recognition that water insecurity – the inability to reliably access sufficient water for all household uses – is commonly experienced globally and has myriad adverse consequences for human well-being. The role of water insecurity in food insecurity and diet quality, however, has received minimal attention. Data are from panel surveys conducted during 2020–21 among adults involved in smallholder agriculture in Niger (n = 364, 3 rounds), Nigeria (n = 501, 5 rounds), Senegal (n = 501, 5 rounds), and Ghana (n = 543, 5 rounds). We hypothesized that household water insecurity (measured using the brief Household Water Insecurity Experiences Scale) would be associated with greater individual food insecurity (using 5 of the 8 Food Insecurity Experiences Scale items) and lower dietary diversity (using the Minimum Dietary Diversity Score for Women). At baseline, 37.1% of individuals were living in water-insecure households and of these, 90.6% had some experience of food insecurity. In multilevel mixed-effects regressions, individuals living in water-insecure households had 1.67 (95% CI: 1.47, 1.89) times higher odds of reporting any food insecurity experience and were estimated to consume 0.38-fewer food groups (95% CI: -0.50, -0.27) than those living in water-secure households. Experiences with suboptimal water access and use are associated with poor nutrition. The pathways by which water insecurity impacts nutrition should be identified. Global and national food and nutrition security policies could be strengthened by monitoring and developing strategies to address household water insecurity.

× We analyze rural households’ purchases of food (cereals and non-cereals) in Sub-Saharan Africa using nationally representative data with 65,000 observations covering 7 countries over a decade. We distinguish between three strata of countries: lower stratum in income and urbanization, middle stratum, and upper stratum. The paper breaks ground by the breadth and time length of the sample. We find that purchases form the majority of rural food consumption whether in favorable or unfavorable agroecological zones and over country and income strata and for most food products. Rural nonfarm employment (as a cash source) plays an important role in household food purchases across all study countries and food products. Policy implications include the importance of food purchase markets and supply chains to and in rural areas as well as nonfarm employment.

× Seed systems are essential to bring good genetic material to farmers. Women farmers, however, have benefited less than men farmers from seed systems in low and middle income countries. We identify factors that inhibit and promote women's success in seed businesses through three case studies of women's and men's entrepreneurship across seed-related value chains and country contexts: tilapia seed production in Ghana, marketing and trading of improved maize and sorghum seeds in Kenya, and chicken seed dissemination in Tanzania. Applying a gender lens, we use key informant interviews and focus group discussions to analyze women's and men's motivations to engage in seed businesses, the challenges they confront to start and build their enterprises, and prospects for sustainability and continued success. We use quantitative data to characterize the levels of empowerment of the agripreneurs sampled. For women, the results show that the social normative context of the sector is critical. Time flexibility and profitability are important considerations for women's engagement. Furthermore, across all three country cases, family and external support are frequently key to women's participation and success in seed agripreneurship. The article discusses the importance of government bodies, NGOs, and donors in challenging the normative context around gender resource gaps, as well as provide technical packages and training to develop business acumen. Supporting change of restrictive gender norms in non-threatening ways - such as ICTs - is key.

× We study experimental measures of preferences for intra-household resource control among 3387 couples in Ghana and Uganda. We implement two incentivized tasks: (1) a game that measures willingness to pay for resource control in the household, and (2) dictator games played privately and jointly by spouses. Across study sites we find that women exhibit a higher willingness to pay for resource control than their husbands and have less influence over joint dictator game decisions. Importantly, behavior in the two tasks is correlated, suggesting that they capture similar underlying latent variables. In Uganda, experimental measures from both tasks are also robustly correlated with a range of survey measures of women's access to resources, agency, and wellbeing. This is not the case in Ghana, suggesting that contextual factors may be important, and researchers may want to collect both measures in a project. Like other recent papers, we find that an important fraction of respondents display negative willingness to pay for intra-household resource control. Our analysis shows that such behavior is displayed by women who have higher levels of economic empowerment and wellbeing, a result that contradicts previous conjectures made in the literature. Altogether, our analysis suggests that, despite lacking ideal theoretical properties, private dictator game decisions (even when collected only from the wife) can perform well as proxies of empowerment.

× Background Gaps persist in the data on diets and on the validity of dietary assessment methods in youth in low-income and middle-income countries (LMICs) due to costs constraints. Although computer vision–assisted dietary assessment tools have been proposed, limited evidence exists on their validity in LMICs.

Objectives This study aimed to validate FRANI (Food Recognition Assistance and Nudging Insights), a mobile phone application with computer vision–assisted dietary assessment, against weighed records (WRs) and compare with 24-h recalls (24HR), in female youth in Ghana.

Methods Dietary intake was assessed on 2 nonconsecutive days using FRANI, WR, and 24HR in females aged 18–24 y recruited at the University of Ghana, Accra (n = 64). Equivalence was examined by comparing intake mean ratios (FRANI/WR and 24HR/WR) with error margins of 10%, 15%, and 20%, using mixed-effect regression models adjusting for repeated measures. Agreement between methods was assessed using the concordance correlation coefficient (CCC).

× There is limited experimental evidence on the effects of large-scale, government-led interventions on human capital in resource-constrained settings. We report results from a randomized trial of the government of Ghana’s school feeding. After two years, the program led to moderate average increases in math and literacy standardized scores among pupils in treatment communities, and to larger achievement gains for girls and disadvantaged children and regions. Improvements in child schooling, cognition, and nutrition constituted suggestive impact mechanisms, especially for educationally-disadvantaged groups. The program combined equitable human capital accumulation with social protection, contributing to the “learning for all” sustainable development agenda.

× Given persistent gender inequalities that influence how the benefits of technologies are distributed, the expansion of small-scale irrigation technologies requires the consideration of important gender dynamics and impacts. Women's lack of agency and access to resources relative to men, and other social constraints, often limit their ability to adopt and benefit from agricultural technologies. At the same time, expanding access to agricultural technology to women may provide a pathway for empowerment. This paper explores the potential for small-scale irrigation technologies to increase women's empowerment by evaluating the impacts of an intervention that distributed motor pumps to small groups of farmers in Northern Ghana. The paper draws on two rounds of survey data that included the Women's Empowerment in Agriculture Index, before and after the motor pump intervention was implemented. To control for possible selection bias at the baseline, the difference-in-difference method is used to estimate the impact of the program on indicators of women's empowerment. Spillover effects are estimated by comparing outcomes of farmers in treatment villages that did not receive the pumps with farmers in control villages, where no motor pumps were distributed. The results show no significant impact of the program on measures of women's empowerment. However, there are potential negative impacts, including among households that did not benefit from the intervention. The results highlight the need to pair interventions that distribute agricultural technologies with complementary investments in infrastructure that increase access to water for irrigation, as well as other activities and approaches that ensure women can reap the benefits.

× This study assesses the institutions and economics of public investments in three agricultural water management infrastructure and technologies: rehabilitation of small reservoirs, fuel-powered motorized small pumps and electricity-powered large pumps. We find that all three technologies yield positive returns on investment, but their applicability varies spatially and across community due to differences in capital costs and environmental feasibilities or conditions. Sensitivity analyses indicate the base decision parameters – net present value, benefit–cost ratio and internal rate of return – remain stable despite potential changes in the flow of future benefits or costs. This provides further evidence about the worthiness of investment in irrigation infrastructure and technologies. However, significant under-utilized infrastructural capacities exist that warrant complementary investment in human and institutional capacities. Based on the findings policy recommendations are provided.

× Despite the adverse effects of pesticides on the environment and human health, they are a key ingredient in boosting agricultural productivity as a way of meeting global food demand. While global levels of pesticides are towering in high-income countries, pesticide use in many parts of Africa remains low, with significant impacts on agricultural productivity and food production. We use a rich longitudinal dataset to examine the relationship between farmer advisory systems and pesticide use in legume-based production systems in Ghana, Mali, and Nigeria. We find that farmers who are advised by private extension systems are approximately 8 % more likely to use pesticides at an extensive level. They also use pesticides more intensively (41 %). On the other hand, farmers advised by public extension systems are about 5 % more likely to extensively use pesticides. These farmers are observed to reduce the intensive use of pesticides by about 14 %. Furthermore, we also show that farmers advised by joint private-public extension systems are about 4 % more likely to use pesticides as well as reduce their intensity of use by approximately 11 %. At the various country levels, there exists significant heterogeneity in the relationship between advisory systems and pesticide use, suggesting that context matters. Of course, the pesticide regulatory systems and the institutional environments in these countries vary greatly. Given these findings, our study offers key entry and leveraging points for increasing pesticide use at levels that limit their environmental and human effects but may ascertain increased agricultural productivity and food production.

× Farmers, entrepreneurs, and businesses are already leading the way by expanding irrigation in response to climate variability and the growing demand for vegetables and fruit through supplemental and dry-season irrigated production. Increasing commercialization creates market opportunities throughout irrigated value chains. The Feed the Future Innovation Lab for Small Scale Irrigation (ILSSI), has supported research and partnerships with companies and producer groups to innovate technologies, share information, and develop inclusive, market-based approaches that catalyze investment in irrigation.

× Evidence indicates that cash transfers can decrease intimate partner violence (IPV) against women, although most research has focused on women's perspectives and experiences, with less attention to men. We analyzed data from four focus group discussions with male partners of women who participated in the Ghana Livelihood Empowerment Against Poverty (LEAP) 1000 cash transfer program. We elicited men's perceptions of poverty, relationship dynamics, IPV and cash transfers targeted to their wives using thematic analysis. Men largely viewed the effects of the cash transfer as positive – they felt decreased provider role strain when women used the cash to cover household expenses such as food and school fees. Men also indicated that they felt respected when women used the cash to cover sudden expenses, such as funeral costs, thus preventing the need to borrow from community members and exposing their inability to fulfill provider roles. These feelings of relief and respect helped improve men's overall wellbeing, their marital relationships and reduced the potential for IPV. Despite these positive results, men revealed that they still expected to be informed and consulted about the transfer and its expenditure, and felt disrespected when women did not do so, thus heightening the potential for household conflict. Further research and innovation in programming is needed to integrate gender transformative strategies into cash transfer programs, explicitly aimed at changing gender norms to enhance and sustain beneficial impacts on gender relations and IPV.

× Individual farmer investments have the potential to fill the gap in public investments and be more cost-effective than large-scale irrigation. However, this development primarily occurs outside of formal systems. Water depletion and declining water quality in some areas of Africa and Southeast Asia suggest the need for careful planning and monitoring of small-scale irrigation to support resilience and avoid maladaptation. ILSSI research partners sought to support decision-makers to understand where and how water can be sustainably used by small-scale irrigators, employing and strengthening capacity for tools to manage competing demands and mitigate the risks to water security. Research partnerships also guided organizations and companies to deploy solar irrigation technologies based on biophysical and socio-economic suitability. Working with farmers, water users, and extension services, the project aimed to improve on-farming water management practices and engage communities to help safeguard water resources.

× Introducing small-scale irrigation can bring opportunities for empowerment and exclusion. To support equity and inclusion, projects must go beyond technology access alone. Situated outside formal public programs, companies and organizations must design market or public interventions to reach women through their preferred information sources, offer technologies suitable for multiple purposes, provide relevant financial tools and credit products, and facilitate market linkages and household cooperation that can help women turn a profit from irrigation. Opportunities for women in irrigated production and value chains can significantly increase the overall number of people adopting and benefitting from small-scale irrigation.

× The evidence on the potential for agricultural interventions to contribute to improved nutrition has grown considerably over the past decade. Numerous studies have explored both positive and negative effects of agriculture on nutrition and health. The Innovation Lab for Small Scale Irrigation has helped to fill the evidence gap on small-scale irrigation and nutrition linkages. The studies, implemented by the International Food Policy Research Institute and national partners, examine the potential of smallscale irrigation as a nutrition-sensitive investment. Through this work, more development partners are recognizing the interconnections and beginning to design irrigation investments to intentionally improve nutritional and health outcomes.

× This paper examines how resilience capacity mediates or moderates the relationship between weather shocks and household food security based on two waves of farm household survey and satellite-based weather data in northern Ghana and applying econometric models. Results show that resilience capacity moderate or mediates the negative effects of heat stress and drought on food security. However, the mediating role of resilience capacity in the shock-food security nexus is more stable and stronger than its moderating role. A standard deviation (SD) increase in heat stress reduces household food consumption by 0.71 SD, but resilience capacity effectively moderates this effect by approximately 0.61 SD. For drought, household food consumption is reduced by 0.67 SD, but resilience capacity effectively dampens this negative effect by approximately 0.60 SD. The mediation results, on the other hand, indicate that 537% of the total effect of heat stress on household calorie consumption is explained by the indirect effect through resilience capacity. Similarly, resilience capacity mediates about 74% of the total effect of heat stress on household food consumption. These results suggest that strategies that help improve resilience capacity, such as the adoption of sustainable intensification practices, are critical in enhancing food security in northern Ghana.

× Background
Important gaps exist in the dietary intake of adolescents in low- and middle-income countries (LMICs), partly due to expensive assessment methods and inaccuracy in portion-size estimation. Dietary assessment tools leveraging mobile technologies exist but only a few have been validated in LMICs.

Objective
We validated Food Recognition Assistance and Nudging Insights (FRANI), a mobile artificial intelligence (AI) dietary assessment application in adolescent females aged 12–18 y (n = 36) in Ghana, against weighed records (WR), and multipass 24-hour recalls (24HR).

Methods
Dietary intake was assessed during 3 nonconsecutive days using FRANI, WRs, and 24HRs. Equivalence of nutrient intake was tested using mixed-effect models adjusted for repeated measures, by comparing ratios (FRANI/WR and 24HR/WR) with equivalence margins at 10%, 15%, and 20% error bounds. Agreement between methods was assessed using the concordance correlation coefficient (CCC).

Results
Equivalence for FRANI and WR was determined at the 10% bound for energy intake, 15% for 5 nutrients (iron, zinc, folate, niacin, and vitamin B6), and 20% for protein, calcium, riboflavin, and thiamine intakes. Comparisons between 24HR and WR estimated equivalence at the 20% bound for energy, carbohydrate, fiber, calcium, thiamine, and vitamin A intakes. The CCCs by nutrient between FRANI and WR ranged between 0.30 and 0.68, which was similar for CCC between 24HR and WR (ranging between 0.38 and 0.67). Comparisons of food consumption episodes from FRANI and WR found 31% omission and 16% intrusion errors. Omission and intrusion errors were lower when comparing 24HR with WR (21% and 13%, respectively).

Conclusions
FRANI AI–assisted dietary assessment could accurately estimate nutrient intake in adolescent females compared with WR in urban Ghana. FRANI estimates were at least as accurate as those provided through 24HR. Further improvements in food recognition and portion estimation in FRANI could reduce errors and improve overall nutrient intake estimations.

× As part of the climate-smart agriculture approach, the adoption of climate resilient crop varieties has the potential to build farmers’ climate resilience but could also induce agricultural transformation in developing nations. We investigate the relationship between adoption of climate-resilient groundnut varieties and production, consumption, and smallholder commercialization using panel data from Ghana, Mali, and Nigeria. We find adoption of climate resilient groundnut varieties to increase smallholder production, consumption, and commercialization. The biggest adoption impact gains are observed under the sustained use of these climate-resilient varieties. We show that adoption benefits all households, but the biggest gains are found among smaller producers, suggesting that adoption is inclusive. Furthermore, we provide suggestive evidence that yield increases could explain commercialization, although household consumption also matters. We conclude that adoption of climate-resilient groundnut varieties can at least partially reduce production constraints and promote smallholder consumption and commercialization, with implications for agricultural transformation.

× Conservation agriculture techniques have the potential to 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 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 yield gains have been achieved.

× This paper introduces a new framework to quantify costs and benefits for resilience-related outcomes of agricultural innovations targeting smallholder farmers. The framework employs a non-unitary household model with expected utility to quantify welfare benefits associated with non-monetary outcomes that are important from a development perspective, such as improved consumption smoothing, empowerment, and changes in time use. We demonstrate the application of the framework using a case study of climate information services (CIS) in Ghana. We develop a set of individual bargaining weights based on the women’s empowerment in agriculture index, to demonstrate how benefits from CIS are distributed among men and women within households. We find that for the average risk-averse farmer, using CIS is associated with a 37-percent increase in expected utility, but male household heads benefit more than women living in male-headed households. Cost–benefit analyses that do not consider the intrahousehold distribution of benefits associated with agricultural innovations will overestimate benefits accruing to women with low bargaining power.

× Global health and development interventions often are predicated on the reallocation of women's time for the achievement of program objectives; yet research and programs have paid limited attention to women's preferences for and agency over their time use. This study aims to develop and validate an instrument to measure time-use agency. It follows a sequenced approach involving qualitative and quantitative research, with exploratory and confirmatory factor analyses and assessment of concurrent validity. The authors conducted surveys with women and men within an impact assessment of a livelihoods program being implemented across rural districts in Ghana. Results indicate a three-factor model with subscales for intrinsic time-use agency, voice related to time use, and decision making related to time use, which were each positively correlated with an item on satisfaction with time use. This time-use agency scale should be validated widely and used within global health and development programs.

× The Feed the Future Innovation Lab for Irrigation and Mechanization Systems (ILIMS), led by the University of Nebraska’s Daugherty Water for Food Global Institute (DWFI) (Nebraska-ILIMS), was fittingly launched at this year’s World Food Day with the theme “Water is Life, Water is Food. Leave No One Behind.”

The research program’s five areas of inquiry will develop socio-technical bundles that support uptake of mechanization and irrigation, strengthen institutions for natural resource governance and climate resilience, enable scaling of suitable technologies and support development of human resources. The fifth area of inquiry makes a leap from technology to nutrition and health, with the specific aim to “formulate strategies for nutrition-sensitive mechanization and irrigation that safeguard and enhance health and inclusivity.”

× In rural sub-Saharan Africa, where malnutrition in all its forms is rife, the greatest gap between the availability of foods and the foods needed for a nutritious diet are faced during the ‘hunger season’. We investigated what rural households in Northern Ghana would need to grow to ensure year-round availability of a nutrient adequate diet or the income required to fulfil their dietary needs. We applied linear programming to model different scenarios and interventions. Our results provide three major insights. First, considering seasonality is crucial in nutrition-sensitive farming. Ensuring a nutritious diet year-round requires enhanced availability of vegetables and fruits throughout the year. Second, although staple crops do not provide the full range of essential nutrients, increasing their yields allows for a reduction of field size, freeing up space for the production of other foods belonging to a nutritious diet, such as vegetables. Third, small farms are unable to produce sufficient food to cover their needs. They depend on income both from agriculture and other sources, and the availability of types of foods on markets to meet their dietary needs. Our study shows the value of modelling the range of dietary effects from agricultural interventions in a specific context, using a local feasible nutritious diet as a starting point and taking seasonality into account.

× In recent years, many developing countries have devolved services to locally elected governments. Although this may strengthen downwards accountability to citizens, does devolution improve service provision? Ghana began devolving agriculture in 2012 to its Metropolitan, Municipal, and District Assemblies (MMDAs). Drawing on an original survey with 80 District Directors of Agriculture and 960 households, as well as district-level budget data and interviews with national and local government stakeholders, this paper shows that agricultural expenditures and services have been negatively affected by the transition. The imperative of electoral accountability encourages assembly members to de-prioritize agriculture in the budget process in favor of more visible goods and services. Budget allocations, however, do reflect the preferences of local citizens, a majority of whom value using elections to sanction their district politicians. The findings indicate that devolution may increase accountability but result in sectoral trade-offs in service provision, which may undermine national policy objectives.

× Over the past decade, the aquaculture sector in Ghana has experienced tremendous growth—driven mainly by large-scale cage aquaculture. Pond aquaculture, traditionally extensive and with limited external inputs, has been transforming over the same period. Farm profitability was wide-ranging, between −12.00 and 46.00 Ghanaian cedi (GHC) per square meter (m2), with an average of GHC 8.82/m2 for farmers active in 2019. Despite wide variability in production and profits, the majority of farmers experienced positive profits—on average, GHC 3.24 per kilogram of tilapia produced, or a 27% profit margin. Farmers who adopted good aquaculture practices and intensified their production have high productivity and positive profits. Nonetheless, the cost to produce 1 kg of tilapia in Ghana (roughly US$1.51 on average) was much higher than in other major tilapia-producing countries (averaging roughly US$0.78 to 1.29). COVID crisis further affected fish farmers: 54% experienced difficulties in accessing inputs, 56% experienced difficulties selling their fish, and farmgate fish prices went down in April–August, although slowly bounced back by end of 2020. Improving the competitiveness and resilience of Ghanaian tilapia sector will require improved seed, increased adoption of good management practices, lower-cost quality feed, and enabling policies and regulations.

× Contract farming has gained in importance in many developing countries. Previous studies analysed effects of contracts on smallholder farmers’ welfare, yet mostly without considering that different types of contractual relationships exist. Here, we examine associations between contract farming and farm household income in the oil palm sector of Ghana, explicitly differentiating between two types of contracts, namely simple marketing contracts and more comprehensive resource-providing contracts. Moreover, we look at different income sources to better understand how both contracts are linked to farmers’ livelihood strategies. We use cross-sectional survey data and regression models. Issues of endogeneity are addressed through measuring farmers' willingness-to-participate in contracts and using this indicator as an additional covariate. Farmers with both types of contracts have significantly higher household incomes than farmers without a contract, yet with notable differences in terms of the income sources. Farmers with a marketing contract allocate more household labour to off-farm activities and thus have higher off-farm income. In contrast, farmers with a resource-providing contract have larger oil palm plantations and thus higher farm incomes. The findings suggest that the two contract types are associated with different livelihood strategies and that disaggregated analysis of different income sources is important to better understand possible underlying mechanisms.

× The current study aimed to understand why child stunting and anemia (CS&A) rates declined in Ghana between 2009 and 2018, and which priority policies and programs will further improve nutrition outcomes. Trends and potential drivers of stunting (height-for-age z-score < -2.0 SD) and anemia (hemoglobin < 11.0 g/dL), and decomposition analysis of DHS data (2003 to 2014) were conducted. The quantitative evidence was triangulated with Net-Map analysis of nutrition stakeholder relationships and influence, desk review of policies and programs 2009–2019, and in-depth interviews with 25 stakeholders who provided additional insights to explain CS&A trends. Declines in stunting (29.6%) and anemia (14.1%) in children were observed at the national level, but with important subgroup variations. Decomposition analyses identified changes in the household, maternal, and child characteristics (including wealth, use of antenatal services, maternal education, and immunization) as correlates of anemia reduction. Stunting reduction was linked with changes in bed-net utilization, household wealth, and pregnancy care service utilization. Additionally, multiple policies and programs initiated/implemented across multiple sectors were considered potentially relevant to CS&A reduction over time, including those focused on infant and young child feeding, water and sanitation, social protection, and health care access. Initiation/strengthening of these interventions was stimulated by awareness creation and subsequently increased prioritization of stunting. However, program delivery was limited by deficits in government funding, perceived low priority of child anemia, low implementation capacity and coverage, and weak coherence across sectors. Reduced CS&A resulted from improved access to services implemented across multiple sectors, albeit limited by implementation scale and capacity. Further reduction in CS&A requires enhanced multi-sectorally coordinated actions and capacity.

× Women’s empowerment is often an important goal of development interventions. This paper explores local perceptions of empowerment in the Upper East Region of Ghana and the pathways through which small-scale irrigation intervention targeted to men and women farmers contributes to women’s empowerment. Using qualitative data collected with 144 farmers and traders through 28 individual interviews and 16 focus group discussions, this paper innovates a framework to integrate the linkages between small-scale irrigation and three dimensions of women’s empowerment: resources, agency, and achievements. The relationship between the components of empowerment and small-scale irrigation are placed within a larger context of social change underlying these relationships. This shows that many women face serious constraints to participating in and benefitting from small-scale irrigation, including difficulties accessing land and water and gender norms that limit women’s ability to control farm assets. Despite these constraints, many women do benefit from participating in irrigated farming activities leading to an increase in their agency and well-being achievements. For some women, these benefits are indirect—these women allocate their time to more preferred activities when the household gains access to modern irrigation technology. The result is a new approach to understanding women’s empowerment in relation to irrigation technology.

× Aquaculture must grow above the current rate of 11% per year to meet projected demand and reduce dependence on seafood imports. Government support and private investment are urgently needed for sustainable growth.

× The effects of agricultural technology adoption on farm performance have been studied extensively but with limited information on who should be targeted during scaling-up. We adopt the newly defined marginal treatment effect approach in examining how farmers’ resource endowment and unobserved factors influence the marginal benefits of adopting sustainable intensification (SI) practices. We estimate both the marginal and average benefits of adopting SI practices and predict which marginal farm household entrants will benefit the most at scale. Findings indicate that farmers’ resource endowment and unobserved factors affect the marginal benefits of adopting SI practices, which also influence maize yield and net returns among adopters. Finally, results imply that scaling up SI practices will favour farm household entrants associated with the lowest probability of adoption based on observed socioeconomic characteristics.

× Diversification is a common livelihood strategy for rural households in developing countries, with diversification being either a choice or necessity depending on individual household contexts. Using two waves of data (from 2009 and 2011) for 1773 households from eight countries in sub-Saharan Africa, we examined livelihood diversification and its drivers. We examined livelihood diversification by considering household involvement in three livelihood activities: crop, livestock, and non-farm. Results indicated that 40% of households conducted all three livelihood activities, but there was heterogeneity in diversity levels. We used a correlated random effects model to identify the factors that pushed or pulled households to diversify their activities. Access to non-agricultural credit was positively associated with livelihood diversity as it can catalyze involvement in non-farm activities. Drought had a negative effect on livelihood diversity. Area of crop land had a positive effect on the number of livelihood activities conducted. We found that 53% of households added or removed at least one livelihood activity between 2009 and 2011, and the addition of non-farm activities was the most common change. Our results demonstrated the dynamic nature of livelihoods and importance of shocks (such as drought) and resource endowments (land) in understanding household livelihood diversification.

× The FAO-IFPRI study, focuses on the use of tractors because they are among the most versatile farm mechanization tools and are universal power sources for all other driven implements and equipment in agriculture, with significant potential to replace animal draught power and human power, including children’s muscle power. Tractor use is typically also the first type of machine-powered equipment in use at lower levels of agricultural development, the context where most child labour is found. Mechanization is mostly assumed to reduce child labour, as it is expected to be labour saving in general. Yet, this is not always the case, as it has also been observed that the use of tractors and other machinery could increase children’s engagement in farm activities. This may be the case if, for instance, their use allows farms to cultivate larger areas, or if it leads to shifting chores of work from hired labor to family workers, e.g. for weeding edges of farmland not reachable by machinery. Evidence has been scant thus far, but the few available studies have mostly lent greater support to the hypothesis that mechanization reduces children’s productive engagement. Most available studies have focused on specific cases and based on scant data. The new FAO-IFPRI study provides a rigorous quantitative assessment for seven developing countries in Asia (India, Nepal and Viet Nam) and sub-Saharan Africa (Ethiopia, Ghana, Nigeria and Tanzania) based on comparable farm household survey data.

× Irrigation has significant potential to enhance productivity, resilience to climatic risks and nutrition security in Sub-Saharan Africa. While the focus has historically been on large-scale dam-based schemes, farmer-managed small-scale irrigation (SSI) has gained increased attention in recent years. Using data from Ethiopia, Tanzania and Ghana, we first examine patterns of adoption of different SSI technologies. Next, we employ hierarchical modelling to examine which variables are associated with observed adoption patterns and cluster effects that explain variation in irrigation adoption. We document significant cross-country variation in adoption patterns and find a positive association between plot-level use of SSI and the intensity of agricultural labor and inorganic fertilizers applied on the plot. Community-level intra-cluster correlation (ICC) is the highest in Tanzania, where gravity-fed irrigation is most common while farm-level ICC is the highest in Ethiopia where motorized technologies are more common. These results suggest the need for localized investments to ease locale-specific potential constraints. For example, easing possible liquidity constraints to acquiring motorized technologies can be more effective in Ethiopia while the construction of dams and improved conveyance systems, as well as the strengthening of community-based irrigation management (e.g., through Water User Associations (WUAs)) can be more effective in Tanzania. Further research is needed to understand pathways for selected plot-level characteristics that affect use of SSI including status of plot ownership and the gender of the plot manager.

× This paper aims to assess the coverage and contribution of different information and communication technology (ICT) tools (mobile phone, WhatsApp platform, television, and radio) in the dissemination of aquaculture and market information to fish farmers in Ghana. Data from a 2021 survey of 391 active fish farmers were analyzed using propensity score matching, inverse probability weighted regression adjustment, and multivariate probit regression models. Mobile phone (phone-based app, internet search, or social media) is the most used ICT tool for aquaculture advice, followed by television programs. Results show that receiving aquaculture information through ICT tools has a positive and significant average treatment effect on the adoption of good management practices, farm productivity, and farmers' income. Farmers receiving aquaculture information from mobile phone and television programs had higher adoption of good practices, production, and income on average. Farmers receiving aquaculture information from both ICT tools and extension agents achieved the highest harvest and income on average. Results also show that the adoption of the various ICT tools is interrelated, whereas several factors—including age, education, farming experience, share of fish farming in household income, and extension contact—influence the choice of ICT tool. Mobile-based extension was more accessible to youth and more educated farmers, and it could be a good medium for reaching these groups. Television and radio programs are accessible to all types of farmers from different backgrounds; these media are currently underutilized for aquaculture promotion and their application could be enhanced and expanded for current and future projects.

× Farm input subsidies are widely used in Sub-Saharan African countries as a response to low adoption of fertilizers and seeds. While subsidy programs traditionally focused on helping farmers access inputs, new generation market smart subsidies additionally emphasize careful targeting, development of input supply systems, and complementary production and marketing support mechanisms. Ghana’s Planting for Food and Jobs (PFJ) initiative, launched in 2017, is one example of such an evolved subsidy program; yet, despite its scale and prominence, the current government monitoring and evaluation system is not well equipped to accurately assess its impacts. This paper triangulates evidence from multiple public sources and independent evaluations to develop a simple and effective impact assessment model for PFJ that can easily be adopted by the government. It can also be adapted to other contexts with minimal adjustment. Model results reveal that maize and rice production levels are more than 40 percent higher than they would have been in the absence of PFJ, thus contributing significantly to food and calorie availability in Ghana. However, there is much room for efficiency improvements that would increase the return on investment-currently, program benefits roughly equal public and private costs of the program. In this regard, several recommendations are made relating to beneficiary targeting, crowding out of commercial input sales, input use efficiency, marketing support to farmers, and improvements in the monitoring and evaluation system, all of which have relevance for other countries implementing or considering similar programs.

× Feed accounts for 60–80% of tilapia production costs, and high feed cost and limited feed access are major issues faced by fish farmers. A potential solution is for farmers to produce their own feeds using cheaper and locally available ingredients. This paper evaluates the feed formulation training implemented in Ghana as part of the Fisheries Commission's activities under the Ghana Aquaculture for Food and Jobs program. This paper analyzes baseline and follow-up survey data using difference-in-difference estimation and analysis of covariance. One year after the training, results show positive impact on the farmers' knowledge of feed formulation, quantity of feed formulated, feeding and management practices, productivity, and income. Feed formulation training encouraged more farmers to formulate their own feeds and maintained or increased total feeds used in their facilities from 2018/2019 to 2020/21. Among the farmers who did not receive training, feed formulation activities and feed quantity used reduced from 2018/19 to 2020/21. A common practice is the use of locally available quality commercial feed as starter feed for smaller fish and own-formulated feeds as a complement for or alternative to commercial growout feeds for bigger fish. Especially when constrained by lack of funds, many farmers reduce the use of commercial feeds and formulate their feeds using cheaper and locally available raw materials to maintain similar levels of feeding intensity. Feed formulation acts as an important coping strategy in the context of small-scale farmers with limited financial resources. This study recommends scaling out feed formulation training and expanding research on optimal fish nutrition using locally available and low-cost raw materials, in combination with commercial feeds to maximize productivity and incomes for farmers.

× A critical, yet underexplored, dimension of food systems is how consumer food preferences and beliefs interact with the food environment. We present a consumer-centered approach to identifying options for improving diets. The Value Chains for Nutrition (VCN) mixed-methods multi-disciplinary analytical approach was applied in rural Ghana. Data from in-depth consumer interviews, structured vendor interviews, and (secondary) household consumption surveys were analyzed to assess consumer diet patterns, related norms and preferences, and supply and demand characteristics of a set of empirically defined high-potential nutritious foods. Mapping results onto a supply–demand typology, we identify promising interventions to support increased availability, access, and affordability of these foods. Consumption data suggested that diets among Ghanaians were deficient in key micronutrients and calories. Fresh nutritious fruits and vegetables tended to be grown for home consumption rather than sale due to transportation challenges and seasonality of demand, especially near rural markets. Seasonal availability (fruits and vegetables) and affordability (animal foods) severely limited consumption of many nutritious foods. A set of supply, demand, and value chain interventions to enhance availability and affordability of nutritious foods are presented. Critical to success is to consider the set of interventions along each value chain required for impact.

× An enabling, evidence-based decision-making framework is critical to support agricultural biotechnology innovation, and to ensure farmers’ access to genetically modified (GM) crops, including orphan crop varieties. A key element, and often a challenge in the decision making process, involves the balancing of identified potential risks with expected economic benefits from GM crops. The latter is particularly challenging in the case of orphan crops, for which solid economic data is scarce. To address this challenge, the International Food Policy Research Institute (IFPRI) in collaboration with local economists analyzed the expected economic benefits to farmers and consumers from the adoption of GM crops in 5 sub-Saharan African countries. This paper focuses on case studies involving insect resistant cowpea in Nigeria and Ghana; disease-resistant cassava in Uganda and Tanzania; and disease-resistant banana in Uganda. Estimations from these case studies show substantial economic benefits to farmers and consumers from the timely adoption and planting in farmers’ fields of GM orphan crops. Our analysis also shows how the benefits would significantly be reduced by regulatory or other delays that affect the timely release of these crops. These findings underscore the importance of having an enabling policy environment and regulatory system—covering, among other elements, biosafety and food/feed safety assessment, and varietal release registration—that is efficient, predictable, and transparent to ensure that the projected economic benefits are delivered and realized in a timely manner.

× Public agriculture expenditure is a significant growth catalyst. However, evaluating the impact of public agriculture expenditure on food security remains scanty. This paper assessed the impact of public expenditure on food security in nine ECOWAS countries using four indicators of food security, one in each dimension (availability, access, utilization and stability). Using a fixed-effect generalized least squares model the study found that public agricultural expenditure has improved. However, this has not translated to an automatic improvement in food security. The levels of stunting and undernourishment were still high in the nine ECOWAS countries. A one-unit increase in public agriculture expenditure was associated with a 0.2% reduction in undernourishment andan improved average dietary energy supply adequacy between 2000 and 2016. The paper concluded that the nine ECOWAS countries have made considerable progress in improving food availability, that public agriculture expenditure by share has increased in the nine ECOWAS countries since the inception of CAADP, with several countries meeting the 10% target of spending on agriculture for several years and that public agricultural expenditure had a positive impact on food accessibility and availability. The analysis could be replicated in the design of national food security investment plans and help identify strategies to accelerate food security and nutrition improvements in African countries.

× Aquaculture in Ghana is experiencing tremendous growth, led mainly by large-scale commercial cage operators. A major objective of the government and its partners is to ensure that this rapid growth is sustainable and includes small-scale farmers and poor rural producers. This paper evaluates the aquaculture trainings implemented in six main tilapia-producing regions in Ghana as part of the Ghana Tilapia Seed Project. The impact evaluation is designed as a cluster randomized controlled trial, with half of the producing districts randomly-assigned as the treatment and the rest as the control, complemented by qualitative interviews. One year after the trainings, results show positive impacts on the adoption of good record-keeping, water management, and some biosecurity practices, and on productivity and incomes. In terms of mechanism, improved management practices resulted from reducing overstocking, reducing inbreeding, maintaining water level for fish ponds, regular pond clearing and establishing physical barriers, following advice and recommendations on feeding practices, and complementing feeding practices with farmers’ own feed formulation. Half of the trained farmers experienced lower fish mortality, faster growth, and heavier fish at harvest. Marketing and processing advice through the trainings and complementary FishConnect WhatsApp platform likely contributed to higher incomes, although the platform's coverage and regular updating can be improved.

× Unhealthy diets are a critical global concern while dietary measure methods are time consuming and expensive. There is limited evidence that phone-based interventions can improve nutrition data collection and dietary quality, especially for adolescents in developing countries. We developed an artificial-intelligence-based phone application called Food Recognition Assistance and Nudging Insights (FRANI) to address these problems. FRANI can recognize foods in images, track food consumption, display statistics and use gamified nudges to give positive feedback on healthy food choice. This study protocol describes the design of new pilot studies aimed at measuring the feasibility (acceptability, adherence, and usability) of FRANI and its effects on the quality of food choice of adolescents in Ghana and Vietnam. In each country, 36 adolescents (12–18 years) will be randomly allocated into two groups: The intervention group with the full version of FRANI and the control group with the functionality limited to image recognition and dietary assessment. Participants in both groups will have their food choices tracked for four weeks. The control groups will then switch to the full version of FRANI and both groups will be tracked for a further 2 weeks to assess acceptability, adherence, and usability. Analysis of outcomes will be by intent to treat and differences in outcomes between intervention and control group will use Poisson and odds ratio regression models, accounting for repeated measures at individual levels. If deemed feasible, acceptable and usable, FRANI will address gaps in the literature and advance the nutrition field by potentially improving the quality of food choices of adolescent girls in developing countries. This pilot study will also provide insights on the design of a large randomized controlled trial. The functioning and dissemination of FRANI can be an important step towards highly scalable nutrition data collection and healthier food choices for a population at risk of malnutrition.

× Although women’s empowerment and gender equality are often linked 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), an 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-, woman-, and child-level dietary and nutrition outcomes. We examine relationships between women’s empowerment and household-level dietary diversity; women’s dietary diversity and BMI; and child-related outcomes, controlling for woman, child, and household characteristics. We also test for differential associations of women’s empowerment with nutrition outcomes for boys and girls. We find few significant associations between the aggregate empowerment scores and nutritional outcomes. The women’s empowerment score is positively associated only with child HAZ, while lower intrahousehold inequality is associated with a higher likelihood of exclusive breastfeeding and higher HAZ but with lower BMI. However, analysis of the subdomain indicators finds more significant associations, suggesting that tradeoffs exist among different dimensions of empowerment. Women’s empowerment accounts for a small share of the variance in nutritional outcomes, with household wealth and country-level factors accounting for the largest share of the variation in household and women’s dietary diversity. In contrast, most of the variation in child outcomes comes from child age. Improving nutritional outcomes requires addressing the underlying determinants of poor nutrition in addition to empowering women and improving gender equality.

× The quality of agricultural products can affect both farm incomes and the healthfulness of farm families’ diets. However, many quality attributes are difficult to observe, making it difficult for farmers to learn how to improve the quality of their crops. Lack of premium pass-through and the cost of quality-enhancing inputs are additional barriers to improving output quality. In this paper, we examine the relative importance of each of these barriers to smallholder adoption of technologies for reducing aflatoxin, a common food safety hazard. We conduct a randomized controlled trial in northern Ghana over the course of two seasons to test how three interventions affect adoption of practices that reduce aflatoxin risk as well as aflatoxin levels in groundnuts: (1) training on aflatoxin and its prevention, (2) distribution of free drying sheets, and (3) a price premium for groundnuts that comply with aflatoxin regulations. We find that training farmers substantially improves post-harvest practices. Drying sheet distribution and, to a lesser extent, the premium price offer lead to further improvements, including crowding-in of non-subsidized practices. We find substantial corresponding decreases in aflatoxin levels from drying sheet provision in the study region with high background aflatoxin levels. Impacts are stronger for households with higher aflatoxin at baseline, more members, and young children.

× Malnutrition in all its forms continues to be a massive global challenge, and the past decade has seen a growing political attention to addressing malnutrition in different contexts. What has been largely missing so far, and is in growing demand from countries, is tangible, practical and rigorous insights and lessons (from other countries or contexts) on how to translate this burgeoning political momentum into effective policies and programme implementation strategies – and ultimately impact on the ground. This new climate of learning from experience and evidence led to the launch in 2015 of the Stories of Change initiative. This series presents a second wave of studies from six countries (Tanzania, Rwanda, Vietnam, Ghana, Burkina Faso, Nigeria,) and three Indian states (Chhattisgarh, Gujarat, Tamil Nadu). These provide clear evidence combined with compelling narratives on what drives success in addressing all forms of malnutrition – evidence that is necessary for turning global momentum into actual results on the ground. This introductory Opinion is published with the first set of papers. It will be followed by a thorough synthesis of papers as a conclusion of the Series. We hope that the lessons embedded in these Stories of Change will inform and inspire the deliberations and outcomes of the UN Food Systems Summit and the second Nutrition for Growth Summit to be held this year, and the actions of those in the global food and nutrition system working for positive change.

× CONTEXT
The accessibility and availability of forages is a common concern in crop-livestock systems in West Africa; however, options to increase forage production may entail trade-offs within the farm system that can be challenging to quantify explicitly.
OBJECTIVE
This study examined how maize (Zea mays L.) leaf stripping affected maize and sheep productivity and associated labour requirements, and farm system trade-offs and synergies in four communities in the Northern Region of Ghana.
METHODS
Maize leaf stripping involved removing almost senesced leaves from maize plants below the cob level at silking. We combined data from three sources: on-farm maize trials with 28 farmers from two seasons (2017 and 2018), on-farm sheep feeding trials where the pasture-based diets of weaner sheep were supplemented with stripped maize leaves fed in pens (conducted in 2019), and farm survey data from 117 households (conducted in 2014), seven of which were in the on-farm maize trials and owned sheep. We examined the trial data using linear mixed-effects models.
RESULTS AND CONCLUSIONS
Maize leaf stripping had no significant effect on maize grain yield but had a significant positive effect on maize forage protein yield from leaf and stover. Offering maize leaves to weaner sheep had a significant positive effect on average daily liveweight gain, estimated marginal mean was 29.3 g with maize leaves and −10.9 g without maize leaves. For the maize-sheep systems of the seven households, non-inferential statistics suggested that on average maize leaf stripping reduced total maize grain production by 12% (range −46 to 38) and increased maize forage protein production from leaf and stover by 90% (range −16 to 298). Stripping the maize leaves from one hectare of land took an extra 34 h (range 27 to 42) of labour, which was counterbalanced by reduced labour time for grazing as sheep were fed the maize leaves in pens. For the 117 farmers, heterogeneity in maize areas planted and livestock numbers resulted in heterogeneous production and labour effects of maize leaf stripping. Farmers qualitatively described how maize leaf stripping released labour so children could spend more time at school rather than shepherding.
SIGNIFICANCE
We quantified in northern Ghana how maize leaf stripping altered crop and livestock productivity and associated trade-offs and synergies in the farm system, including labour. Changes in crop management often have implications beyond the crop's field and examining these implications can provide insights into the suitability of alternative farm management options.

× Effective policy requires an accurate understanding of peoples’ livelihoods activities. The data for this evidence is often generated via lengthy surveys where designated respondents provide information about their household members. This burden on respondents may lead to both losses and biases as they grow fatigued during the interview. We test these hypotheses with an experiment in rural Ghana where we randomize individual household members’ position in the labor module. We find that moving a household member back by one position reduces their reported number of productive activities by 2.2% with average aggregate losses of 7.9%, or approximately one out of every twelve activities. Losses for women and youth are closer to one in nine. These biases result from both differential exposure to response fatigue (being positioned later in rosters) and differential vulnerability (greater impacts conditional on position). These results have important implications for data quality across many settings and topics.

× This study analyzed the impact of adoption of artificial pollination on productivity, income, poverty and food security among cocoa farmers in Ghana. Primary data was collected from 206 cocoa farmers drawn through a multi-stage sampling technique and analyzed using Propensity Score Matching. The study revealed that households who adopted artificial pollination had improvements in their productivity, income, poverty situation, and food security. It was also revealed that adopters increased their productivity by close to 15.34% on average, earned between GH₵ 2756.84 to GH₵ 11074.38 more on average in terms of income, reduced their poverty by an average of between 0.83% and 3.53%, and finally, improved their food security by approximately 3% compared to non-adopters. Leveraging on the positive impact of adoption of artificial pollination, policymakers should take steps in implementing artificial pollination to help increase the yield of Ghana’s cocoa.

× We adopt the newly redefined marginal treatment effect (MTE) framework to examine how farmers' resource endowment and unobserved factors affect the marginal benefit of adopting sustainable intensification of agricultural practices (SI practices), estimate the average and the marginal benefits of adopting the SI practices, and identify the farm households at the margin of participation that need to be targeted during scaling-up. Findings show that farmers’ unobserved factors and resource endowment influence the marginal benefit of adopting SI practices. Point estimates indicate that the adoption of SI practices increases the maize yield and net returns of adopters. Estimates further reveal that the average benefit for adopters differ from the marginal benefit for new farmers at the margin of participation. Finally, our findings suggest that not all farm households at the marginal entrants would benefit from all the potential scaling-up policy options, except households who by socio-economic characteristics appear least likely to adopt. We conclude that these households should be targeted to enhance adoption as well as maximize the return on investment during scaling-up of the SI practices

× The FAO-IFPRI study, of which this policy brief is a summary, focuses on the use of tractors because they are among the most versatile farm mechanization tools and are universal power sources for all other driven implements and equipment in agriculture, with significant potential to replace animal draught power and human power, including children’s muscle power. Tractor use is typically also the first type of machine-powered equipment in use at lower levels of agricultural development, the context where most child labour is found. Mechanization is mostly assumed to reduce child labour, as it is expected to be labour saving in general. Yet, this is not always the case, as it has also been observed that the use of tractors and other machinery could increase children’s engagement in farm activities. This may be the case if, for instance, their use allows farms to cultivate larger areas, or if it leads to shifting chores of work from hired labor to family workers, e.g. for weeding edges of farmland not reachable by machinery. Evidence has been scant thus far, but the few available studies have mostly lent greater support to the hypothesis that mechanization reduces children’s productive engagement. Most available studies have focused on specific cases and based on scant data. The new FAO-IFPRI study provides a rigorous quantitative assessment for seven developing countries in Asia (India, Nepal and Viet Nam) and sub-Saharan Africa (Ethiopia, Ghana, Nigeria and Tanzania) based on comparable farm household survey data.

× Our paper seeks to identify factors that inhibit and promote women’s success in seed businesses, through three case studies of women’s and men’s entrepreneurship across varying seed-related value chains and country contexts in Africa south of the Sahara. The cases include chicken seed dissemination in Ethiopia and Tanzania, tilapia seed production in Ghana, and marketing and trading of improved maize and sorghum seeds in Kenya. Applying a gender lens, we use qualitative methods to analyze women’s and men’s motivations to engage in seed businesses, the challenges they confront to start and succeed, and prospects for sustainability and continued success. We also use quantitative data to characterize the levels of empowerment of the entrepreneurs sampled. Results show that time flexibility and profitability of the business can be important considerations for women’s engagement in seed entrepreneurship, and the social normative context of the sector is also critical. Furthermore, outside support can be a key factor influencing women’s seed entrepreneurship, per the Kenya case.

× Many smallholder farmers in developing countries grow multiple crop species on their farms, maintaining de facto crop diversity. Rarely do agricultural development strategies consider this crop diversity as an entry point for fostering agricultural innovation. This paper presents a case study, from an agricultural research-for-development project in northern Ghana, which examines the relationship between crop diversity and self-consumption of food crops, and cash income from crops sold by smallholder farmers in the target areas. By testing the presence and direction of these relationships, it is possible to assess whether smallholder farmers may benefit more from a diversification or a specialization agricultural development strategy for improving their livelihoods. Based on a household survey of 637 randomly selected households, we calculated crop diversity as well as its contribution to self-consumption (measured as imputed monetary value) and to cash income for each household. With these data we estimated a system of three simultaneous equations. Results show that households maintained high levels of crop diversity: up to eight crops grown, with an-average of 3.2 per household, and with less than 5% having a null or very low level of crop diversity. The value of crop species used for self-consumption was on average 55% higher than that of crop sales. Regression results show that crop diversity is positively associated with self-consumption of food crops, and cash income from crops sold. This finding suggests that increasing crop diversity opens market opportunities for households, while still contributing to self-consumption. Given these findings, crop diversification seems to be more beneficial to these farmers than specialization. For these diversified farmers, or others in similar contexts, interventions that assess and build on their de facto crop diversity are probably more likely to be successful.

× In the existing literature, the effects of contract farming on household welfare were examined with mixed results. Most studies looked at single contract types. This paper contributes to the literature by comparing two types of contracts – simple marketing contracts and resource providing contracts – in the Ghanaian oil palm sector. We investigate the effects of both contracts on farm income, as well as spillovers on other household income sources. We use survey data collected with an innovative sampling design and a control function approach to address possible issues of endogeneity. Both contracts lead to large positive effects on total household income in a similar magnitude, yet through quite different mechanisms. Farmers under the marketing contract use the increase in oil palm profits to transition out of agricultural production and into off-farm employment. Farmers under the resource-providing contract have a stronger dependency on income from oil palm, which is considerably more profitable under the contract. The findings underline that contract characteristics matter for the effects and that disaggregated analysis of different income sources is important to understand the underlying mechanisms.

× The urban population in Sub-Saharan Africa is projected to expand by nearly 800 million people in the next 30 years. How this rapid urban transition is affecting household-level urban food security, and reverberating into broader food systems, is poorly understood. To fill this gap, we use data from a 2017 survey (n = 668) of low- and middle-income residents of Accra, Ghana, to characterize and compare the predictors of household-level food security using three established metrics: the Household Food Insecurity Access Scale (HFIAS); the Household Food Insecurity Access Prevalence (HFIAP); and the Food Consumption Score (FCS). According to HFIAP, 70% of sampled households are food insecure, but only 2% fall below acceptable thresholds measured by FCS. Only one household reported sourcing food from modern supermarkets and fewer than 3% produce food for consumption through gardening, farming, or fishing. Instead, households rely on purchased food from traditional markets, local stalls and kiosks, and street hawkers. Results from a suite of general linear models show that household assets, education, and demographic characteristics are significantly associated with food security outcomes according to HFIAS and HFIAP. The poor correlation and weak model agreement between dietary recall such as FCS, and experience-based food security metrics, like HFIAS and HFIAP, highlight limitations of employing historically rural-centric food security measurement approaches within the urban context. Given that Sub-Saharan Africa’s future is urban, our results add empirical evidence in support of the growing chorus of scholars advocating for comprehensive urban-oriented food security research and policy agendas across Sub-Saharan Africa.

× More than 20 million young people, aged 15-24 years, join the workforce in Africa south of the Sahara every year. These young job seekers will need to find work in today’s more competitive global economy, and not everyone thinks they will be successful.

× This manual provides a comprehensive step-by-step guide to pond aquaculture. It includes tips on site selection, site preparation, pond design and construction, farming practices (pond preparation, stocking, and feeding), biosecurity and fish health management, harvesting and marketing and recordkeeping - all of which are critical elements of a successful tilapia pond aqua-farming business operation. Aquaculture has existed in Ghana since the 1950s, though the sector didn’t experience major growth until around 2000, when large-scale commercial production began. Today, it plays a key role in the nation’s prosperity, contributing to food security by augmenting domestic fish production and creating jobs. Even so, challenges that have historically plagued the sector and hindered growth remain pervasive. These include low technical know-how and a lack of quality inputs such as seed and feed. Although knowledge in the sector has increased over the years, small-scale farmers (most of whom are indigenous) continue to struggle with basic farming practices. As a result, they’re often faced with poor yields, which can ultimately lead to a farm’s collapse. The Tilapia Seed Project is aimed at accelerating quality tilapia seed production and dissemination in Ghana. Project stakeholders produced this manual to provide accurate direction to small-scale fish farmers in Ghana. After reviewing its contents, we expect that it will prove instrumental in helping farmers improve production, and that it will serve as a valuable catalyst for growth in this important sector.

× mNutrition was a five-year global initiative supported by the Department for International Development (DFID) between 2013 and 2018, organised by GSMA and implemented by in-country mobile network operators (MNOs) and other providers. The evaluation was carried out by a consortium of researchers from Gamos, the Institute of Development Studies, and the International Food Policy Research Institute. This briefing summarises key evaluation findings and presents lessons learned on three key topics: 1. The design and implementation of mobile phone-based information services to promote behaviour change; 2. Building a commercially viable business model for mobile phone-based information services; and 3. Evaluating mobile phone-based information services.

× This article presents key lessons learned from a rigorous mixed-method evaluation of mNutrition, a global mobile phone-based advisory service that promotes behavioural change around key nutrition and farming practices to boost the nutritional health of children and adults in low-income countries. The evaluation found that the reach and sustained uptake of mobile mNutrition services remain a challenge among very poor households, with women often being excluded. mNutrition services currently have limited effect on nutrition and agriculture behaviours at scale, although active users (those users who adopted and engaged with the service) report some behavioural change. Still, well-designed mNutrition services can provide individually tailored, practical and context-specific advice that is often lacking from other information sources. Mobile phone-based advisory services alone tend to be insufficient to ensure uptake, engagement and behavioural change. In-person support features may help, but also raise the cost of the service.

× Recent agricultural transformation in Asia and Africa has witnessed the gradual spread of mechanization in agricultural areas that are still largely made up of smallholder farming. While the literature has often characterized mechanical technologies as being complementary to land, knowledge gaps exist with regard to the process of adoption of mechanization by smallholders for whom the scope for exploiting its complementarity with land is limited. We test a hypothesis that yield-enhancing biological technologies—which potentially raise total factor productivity and returns to more intensive farm-power use—are important drivers of the adoption of agricultural mechanization among smallholders. To enhance the external validity of evidence, we empirically analyze this hypothesis by applying the same methodologies in two countries, lowland (Terai) Nepal and Ghana. We employ nationally representative, repeated, cross-sectional data from both countries, as well as unique tractor-use data from Ghana; we also employ multidimensional indicators of agroclimatic similarity in the respective plant breeding locations. We show that in both lowland Nepal and Ghana, the adoption of tractors and agricultural equipment has been induced by yield-enhancing biological technologies, particularly improved varieties and high-yielding production systems, when these biological technologies are instrumented by agroclimatic similarity to plant breeding locations, which is measured accounting for the multidimensional characteristics of agroclimatic conditions, and thus proxies spillover potentials of the public sector developed biological technologies. In general, these effects are particularly strong among smaller farms, and the effect holds for the adoption of mechanization both at extensive margins (whether to adopt) and at intensive margins (how much to adopt). In Ghana, partly due to improved efficiency in supply-side factors of mechanization, these linkages have strengthened in the 2010s. The results suggest that in both countries, mechanization support strategies for smallholders can potentially improve their targeting by utilizing the information of agroclimatic similarity with plant breeding locations. In Ghana, further public investments in plant-breeding system in strategic locations may broadly enhance smallholders' demand for mechanization. In lowland Nepal where tractor adoptions have grown fairly high, it is now important to more carefully evaluate the trade-off between smallholder-based growth strategies and other strategies, for example, promoting scale-expansions of farming, which also involves mechanization.

× The sex differences in malnutrition and hypertension during adolescence is largely inconclusive. There is also a paucity of data on the sex-specific correlates of malnutrition and hypertension for adolescents. Hence, this study aimed to assess the association between malnutrition, pre-hypertension/hypertension (PHH) and sex among adolescents. The study also aimed to determine and contrast the factors associated with these risks in Ghana. We analysed data of non-pregnant adolescent girls (n = 857) and adolescent boys (n = 870) aged 15–19 years from the 2014 Ghana Demographic and Health Survey (DHS). We modelled the prevalence risk ratio (PRR) of malnutrition and PHH using Cox proportional hazard models. Compared to adolescent girls, boys were more than twice likely to be stunted (PRR = 2.58, 95% C.I (1.77, 3.76)) and underweight (PRR = 2.67, 95% C.I (1.41, 5.09)) but less likely to be overweight/obese (PRR = 0.85, 95% C.I (0.08, 0.29)). Boys were also about twice likely to have PHH (PRR = 1.96, 95% C.I (1.47, 2.59)) compared to their female peers. Girls were more at risk of the detrimental effects of poor education on stunting and PHH. Empowerment index while protective of stunting for girls (PRR = 0.82, 95% C.I (0.67, 0.99)) also increased their risk of overweight/obesity (PRR = 1.31, 95% C.I (1.02, 1.68)). A higher household wealth index (HWI) increased the risk of overweight/obesity for adolescent girls but was protective of stunting and PHH for adolescent boys. Improvement in household water, hygiene, and sanitation (WASH) reduced the risk of stunting by 15% for adolescent boys. Overall, our findings suggest a double-burden of malnutrition with an up-coming non-communicable disease burden for adolescents in Ghana. Our findings may also be highlighting the need to target adolescent boys alongside girls in nutrition and health intervention programmes.

× Globally, countries have resorted to social distancing, travel restrictions and economic lockdowns to reduce transmission of COVID-19. The socioeconomic costs of these blunt measures are expected to be high, especially in sub-Saharan Africa where many live hand-to-mouth and lack social safety nets. Social Accounting Matrix multiplier model results show that Ghana’s urban lockdown, although in force for only three weeks in April 2020, has likely caused GDP to fall by 27.9% during that period, while an additional 3.8 million Ghanaians temporarily became poor. Compared to the government’s revised GDP growth rate of 1.5% for 2020, the model predicts a contraction of 0.6 to 6.3% for 2020, depending on the speed of the recovery. The US$200 million budgeted for Ghana’s Coronavirus Alleviation Program will close only a small part of the estimated US$ 2.3 billion GDP gap between the fast recovery scenario and government’s revised GDP trajectory.

× Understanding contextual risk factors for haemoglobin (Hb) status and anaemia of rural school‐aged children (SAC) and adolescents is critical in developing appropriate interventions to prevent anaemia. We analysed secondary data from the baseline of an impact evaluation of the Ghana School Feeding Programme to determine the severity of anaemia and contextual factors associated with anaemia and Hb status among rural SAC (6–9 years; n = 323) and adolescents (10–17 years; n = 319) in Ghana. We used regression models with variable selection based on backward elimination in our analyses. The mean Hb was 113.8 ± 13.1 g/L, and the overall prevalence of anaemia was 52.3%, being 55.1% and 49.5% among SAC and adolescents, respectively. We identified child's age (β = 2.21, P < 0.001); farm diversity score (β = 0.59, P = 0.036); and agro‐ecological zone (P trend <0.001) as the main predictors of Hb of SAC. Household asset index (P trend = 0.042) and agro‐ecological zone (P trend <0.001) were predictors of Hb in adolescents. Agro‐ecological zone and age were predictors of anaemia, but the effect of age was only significant for girls and not boys (prevalence odds ratio [POR] = 1.35, 95% CI [1.04, 1.76] vs. POR = 1.14, 95% CI [0.88, 1.46]). SAC in households with maize stock were less likely to be anaemic (POR = 0.55, 95% CI [0.32, 0.97]). Household dietary diversity score (β = 0.59, P = 0.033) was associated with Hb status for the full sample only. Anaemia is a severe public health problem among SAC and adolescents in rural Ghana irrespective of sex. Farm diversity score, availability of maize stock in the household, household asset index, and agro‐ecological zone were the main predictors of Hb and anaemia among the rural SAC and adolescents.

× 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 participants in Ghana, we elicit preferences among both men and women for investments in crop farming versus alternative income-generating activities. We analyze gender differences in preferences and whether these can be ascribed to differential access to physical and human capital, or to differences in socio-economic characteristics, skills, perceptions and norms. We find that many respondents prefer to invest in both farm and non-farm activities. Women prefer investing significantly more towards non-farm diversification than men, but the gender gap is much smaller than expected a priori. Differential access to physical and human capital does not appear to explain this gap. Rather, the gender gap is associated with gender stereotyping of
perceived skills. We conclude that both men and women reveal a strong preference for a diversity of income-generating activities, which needs to be reflected in programs and policies aiming to improve women’s economic empowerment.

× Attention to nutrition during all phases of child and adolescent development is necessary to ensure healthy physical growth and to protect investments made earlier in life. Leveraging school meals programs as platforms to scale-up nutrition interventions is relevant as programs function in nearly every country in the world.

× Recent growth in many African countries has been accompanied by rapid urbanization, which could have major impacts on rural livelihoods. This paper examines patterns of rural livelihoods and poverty in Ghana based on the proximity of rural areas to cities of different sizes. The paper finds that many rural households in the areas close to cities have shifted their primary employment from agriculture to nonagriculture, especially in the more urbanized South. This trend strengthens over time. This appears to take place in contrast to the traditional model of rural livelihood diversification, with some family members working in agriculture and some in nonagriculture. Although cities have created market demand for agriculture, proximity to cities does not seem to influence agricultural intensification in terms of modern input use, possibly due to agricultural markets being relatively integrated in Ghana. Proximity to cities has implications for rural households being less poor and becoming middle class even after controlling for being a nonfarm household in rural areas.

× Changing precipitation patterns caused by climate change are expected to have major impacts on food security and nutrition in agrarian areas in developing countries. However, the linkages between the duration and severity of precipitation shocks and their effects on child nutrition and household food security metrics remain underexplored. In this study, we used Feed the Future datasets from Ghana and Bangladesh to examine the impact of precipitation extremes on nutrition, measured by children’s height-for-age and weight-for-height Z-scores, and food security, measured by the Household Hunger Scale. We used a spatial error regression to control for the effects of spatial autocorrelation, and we found an association between precipitation shocks and household hunger in both Ghana and Bangladesh, as well as an association between higher rainfall and worse child nutrition in Ghana.

× Ghana has been viewed as one of Africa's political and economic success stories, from maintaining a multi-party democracy, peace and social cohesion to reducing poverty and growing its middle class. Yet, despite 30 years of continuous growth in per capita income and rapid urbanization, the country has not been able to industrialize and most of the workforce is either trapped in traditional agriculture or low-productivity jobs in the services sector. Agriculture holds the potential to help bring about more sustainable and equitable patterns of growth, but public and private actors will need to adjust course in order to achieve it.

× Objectives: To define key stressors experienced and coping behaviours within poor agrarian communities in sub-Saharan Africa.

× 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 joint control over technology by men and women in the same household. Efforts to promote technology adoption for agricultural development and women’s empowerment would benefit from an understanding of intrahousehold control over technology to avoid interpreting technology adoption as an end in and of itself.

× There are concerns that increasing women’s engagement in agriculture could negatively affect nutrition by limiting the time available for nutrition-improving reproductive work. However, very few empirical studies provide evidence to support these concerns. This paper examines the relationship between women’s time spent in domestic work and agriculture and women’s and children’s dietary diversity. Using data from Bangladesh, Nepal, Cambodia, Ghana, and Mozambique, we find that women’s domestic work and cooking time are positively correlated with more diverse diets. We also find differential effects depending on asset poverty status. In Mozambique, working long hours in agriculture is negatively associated with women’s dietary diversity score in nonpoor women, but is positively associated with poor women’s dietary diversity and poor children’s minimum acceptable diet. This suggests that agriculture as a source of food and income is particularly important for the asset poor. Our results reveal that women’s time allocation and nutrition responses to agricultural interventions are likely to vary by socioeconomic status and local context.

× Using data from two culturally distinct locales, Bangladesh and Ghana, we investigate whether men and women who report sole decision making in a particular domain experience stronger (or weaker) feelings of autonomous motivation—measured using the Relative Autonomy Index (RAI)—compared to those who report joint decision making. Used primarily in psychology, the RAI measures the extent to which an individual’s actions are intrinsically or extrinsically motivated, where higher scores indicate greater autonomy. On aggregate, we find differences between men and women, and across countries, in the significance of association between the individual’s level of participation in decision-making and autonomy. In addition, we find heterogeneity in the strength of this association, depending on the domain (e.g., productive versus personal decisions) and whether partners agree on who normally makes decisions. These findings imply that details related to context and measurement matter for understanding individual decision-making power. We argue that all research using information on decision-making should include a careful analysis of men’s and women’s perceptions of decision making within the household, which may be useful for calibrating indicators to suit spicific contexts

× Africa south of the Sahara experienced an acceleration of economic growth in recent years that was accompanied by structural changes in national economies. Some African countries, such as Ghana, managed to utilize rapid growth for poverty reduction and improving food and nutrition security. Transformation of agriculture appears to have played an important role in this context. However, the linkages between agricultural transformation and food and nutrition security at the household level are not well understood. This article examines the linkage between farm production diversity and household dietary diversity in rural Ghana and how that linkage changed between 2005–06 and 2012–13. The empirical analysis employs a regression model that controls for region- and time-fixed effects. The estimation results suggest that farm production diversification, as well as household income growth, continues to be strongly associated with increased household dietary diversity. The analysis further explores the mechanism that underlies this production-consumption linkage by systematically modifying the basic model specification.

× If you asked most Ghanaians where the opportunities of the future lie, they would point to Accra, Kumasi, and other big cities. The country’s thousands of small farms symbolize the past—and they symbolize poverty. But this dichotomy misses an important point. Agriculture is not going away; it is transforming. Subsistence farming may be gradually disappearing (the number of Ghanaians who say farming is their primary job fell from 57 to 44 percent between 2006 and 2016), but it is being replaced by a more dynamic, productive, market-oriented agriculture.

× This paper summarizes evidence on six perceptions associated with cash transfer programming, using eight rigorous evaluations conducted on large-scale government unconditional cash transfers in sub-Saharan Africa under the Transfer Project. Specifically, it investigates if transfers: 1) induce higher spending on alcohol or tobacco; 2) are fully consumed (rather than invested); 3) create dependency (reduce participation in productive activities); 4) increase fertility; 5) lead to negative community-level economic impacts (including price distortion and inflation); and 6) are fiscally unsustainable. The paper presents evidence refuting each claim, leading to the conclusion that these perceptions—insofar as they are utilized in policy debates—undercut potential improvements in well-being and livelihood strengthening among the poor, which these programs can bring about in sub-Saharan Africa, and globally. It concludes by underscoring outstanding research gaps and policy implications for the continued expansion of unconditional cash transfers in the region and beyond.

× We explore the determinants of firm exit and growth in the food processing sector using nationally representative data for 745 firms in Ghana. In our sample, 168 of the firms exited the sector during the period 2014-2017. Firms were more likely to exit if they were in a rural district, were younger, and were involved in grain milling, but there was little impact of firm size on the likelihood of exit. In terms of firm growth, we find that tax registration, combined with registration with the national food regulator, had positive impacts on firm growth, while tax registration alone has a weaker effect. Therefore, for the food processing sector, efforts to promote formalization of firms for tax purposes would yield greater benefits if firms are also encouraged to undergo regulatory inspections and certification.

× Using public expenditure and agricultural production data on Ghana from 1961 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. Different regression methods and related
diagnostic tests are used to address potential endogeneity of agricultural expenditure, crosssubsector
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 to expenditures in the sector as a whole and within the two subsectors.
The elasticity of land productivity with respect to total agricultural expenditure is
estimated at 0.33–0.34. For the noncocoa subsector, the estimated elasticity is 0.66–0.81. And
in the cocoa subsector, it is 0.36–0.43. The returns to total agricultural expenditure are
estimated at 82–84 percent for the aggregate analysis. For the disaggregated sectorial
analysis, the returns to expenditure in the noncocoa subsector are estimated at 437–524
percent, whereas the returns to expenditure in the cocoa subsector are estimated at 11–14
percent. Implications are discussed for raising overall productivity of expenditure in the
sector, as well as for further studies.

× This document presents a summary of a typology study done using quantitative statistical methods (discussed below) applied to micro data from the Ghana Africa RISING Baseline Evaluation Survey (GARBES) (conducted in 2014) and secondary data on environmental/biophysical variables from various source. The quantitative approaches have the advantage that they are reproducible and do not impose any ex-ante structure to the clustering process, while more qualitative approaches can potentially incorporate less tangible insights such as cultural patterns. Once the different farm types are identified through systematic quantitative analysis, they need to be validated with input from Africa RISING colleagues (especially working in Ghana).
