Agricultural trade in Africa: Current trends and challenges

Agricultural trade can play a central role in meeting people’s food needs, both by increasing available supply and by boosting stakeholders’ incomes, given that 60% of the labor force works in this sector (Bonuedi et al., 2020; Wonyra and Gnedeka 2023). However, an analysis of African agricultural trade performance over the past twenty years highlights some key issues to watch. First, African agricultural trade is the lowest in the world, not helped by high costs of trading and non-tariff measures. Second, a trade deficit that has been steadily widening since 2006 as Africa has become heavily dependent on imports of basic agricultural products such as cereals. The continent currently meets more than 40% of its cereal demand on world markets. This deficit in African agricultural trade is fueled by low productivity, linked to declining yields and a lack of sufficient investment in production, storage, processing, and marketing infrastructure, and rapid population growth and urbanization in Africa which has increased demand for imported food. Third, over the past two decades, the structure of African agricultural exports has remained largely undiversified, with unprocessed cash crops continuing to be the dominant export commodity. To better understand the dynamics of agricultural trade in Africa, this brief analyzes its performance, over the 2003-2023 period, by highlighting the most dynamic countries and regional economic communities, the most exported and imported products, and the continent’s revealed comparative advantages.

Mindset or economics: What explains the dominance of maize in Malawi

Malawi’s policy ambitions increasingly emphasize the need for greater crop and diet diversity. De-spite these stated goals, the country’s food system continues to revolve around maize, both in pro-duction and consumption. This brief discusses the economic imperatives that drive low-income, land-constrained Malawians to prioritize maize. Only by addressing these underlying incentives can policy effectively reduce maize dominance and support the diversification agenda it seeks to advance.

Sudan: How warring factions gained influence in the country’s food system – and what it means for the current conflict

Militaries play a major role in the politics of many countries. They determine whether elections can occur and who can compete. From Egypt to Pakistan and Myanmar to Uganda, the military is often the most important powerholder. In parallel, violent non-state actors – including criminal networks, terrorist groups and paramilitaries – have proliferated over the last two decades. To maintain their influence and finance their operations, militaries and violent non-state actors often become heavily involved in both legal and illicit business activities. Studies of their economic activities often focus on their role in extracting natural resources like gold, oil and timber.

Synopsis: Implications of increased urbanization and consumer awareness on future food supplies in Tanzania

This research quantifies how demographic change, urbanization, and healthy diet requirements will reshape Tanzania’s food supply. Using contextualized healthy diet benchmarks, it identifies the scale, composition, and policy implications of food system transformation needed to ensure healthy diets in Tanzania by 2050.

Tanzania’s population is projected to more than double by 2050, with rapid urbanization increasing the share of urban residents from one-third to more than half and intensifying pressure on food supply systems and rural–urban linkages.

To align with this growth, annual food supplies also need to increase by more than double—from about 24 million tons in 2020/21 to 52–62 million tons by 2050—but must do so with fewer food producers.

Current diets are dominated by cereals and sugar, while fruits, vegetables, dairy, eggs, and animalsource foods are substantially under-consumed across all four geographic population strata.

Future food system transformation should primarily focus on increasing supplies of dairy, eggs, fruits, and vegetables, and, for diets focused on micronutrients, meat and fish.

For most priority foods, required productivity gains fall within current global technological frontiers, but environmental constraints—particularly for livestock—necessitate climate-smart intensification and protein source substitution.

High postharvest losses, misalignment between nutrition priorities and agricultural policy—specifically Tanzania’s Agriculture Master Plan—and weak rural–urban food system integration are critical bottlenecks and policy entry points for achieving healthy diets sustainably.

IFPRI Malawi maize market report, January 2026

Average retail prices of maize declined in all monitored markets in January by 16 percent on average. The price decline was driven by cheap imports of maize. Imports dominated cross-border trade in maize despite some strong but localized informal exports to Zambia.

Assessment of potato tuber quality in Kenya: Baseline quality assessment survey report

Potato is the second most important staple crop in Kenya after maize, supporting its food security and providing livelihoods for millions in the value chain, including over 800,000 smallholder farmers. However, fragmented marketing systems, inadequate post-harvest infrastructure, and limited access to quality inputs constrain the performance of the sector and result in severe post-harvest losses. This qualitative study provides empirical analysis on potato tuber quality among 233 farmers in Nakuru and Nyandarua counties, and among traders six different main markets in Kenya. Our findings establish a baseline for potato quality at the farm-level and in major markets, tracking individual shipments to measure degradation during transit due to lack of crucial market conditions and logistical bottlenecks. Our main results reveal some important elements that need to be addressed. Overall, potato quality is compromised at the farm gate, but this initial damage is dramatically amplified post-harvest, with skin abrasions more than doubling and rotting increasing threefold as produce moves along the value chain. Critically, these losses are compounded by limited quality-based sorting and the inadequate use of storage infrastructure, with negligible adoption of cold storage. The study also demonstrates that local/traditional handling practices and poor infrastructure quality are bigger drivers of loss than transport distance. Our research concludes that most economic losses could be addressed, being the direct result of identifiable failures in infrastructure, handling, access to information, and quality governance throughout the value chain. Most aspects of which can be mitigated with digital tools. Indeed, digital tools can enhance farmer-buyer linkages, promote digital education and advisory services -also through collaboration with Farmer Service Centers, encourage cold storage via digital incentives. These recommendations position digital tools as a catalyst for transforming the potato value chain, both directly and indirectly mitigating post-harvest losses while boosting resilience and incomes.

The potential impact of wheat stem rust on global agricultural supply, demand, and food security, considering market interactions

Wheat stem rust, a fungal disease that can be highly devastating under the right environmental conditions, was reduced to non-economically damaging levels during the Green Revolution. However, it has reemerged as a global threat to wheat production due to the appearance of new virulent strains in Uganda in 1999 that have spread steadily to other geographic areas. Wheat experts warn that the disease could pose a catastrophic threat to the global wheat supply if not monitored. Considering the importance of wheat as a principal source of calories, nutrients, and farm income throughout the world, assessments of the potential impacts of the disease are urgently required in order to formulate an appropriate response. Published assessments so far vary widely in method and results, and generally focus on wheat production losses alone, without considering how markets may offset or aggravate impacts (spillover effects). Here we take an integrated assessment approach and examine a set of “what-if” scenarios to account for direct and indirect economic and food security impacts of wheat stem rust in various world regions over the years 2026–2050. The severity and frequency of epidemics is introduced into the modeling framework based on a survey of international wheat experts. The results suggest that global market incentives may offset the worst impacts of wheat stem rust in most affected areas via international trade. However, the market mechanism simultaneously precipitates considerable food insecurity in areas far from any epidemic, as farms in these areas reallocate resources from the domestic cereal market to the wheat export market, in response to price signals.

Can digital cash transfers serve those in active conflict zones?

Digital cash transfers can be delivered even in active conflict settings like Sudan and can significantly protect vulnerable households – especially in the most insecure areas – from worsening food insecurity, though their impacts vary by context and household characteristics.

Market channel and other drivers of tomato farmer production and handling practices in Nigeria

Non-contract farming arrangements remain the dominant marketing option for poor, often food-insecure smallholder farmers in low-and middle-income countries (LMICs), yet such farming arrangements are less studied than contract farming. Using a case study of 1,673 Nigerian tomato farmers, this study examined whether selling to midstream actors such as wholesalers and aggregators (via informal market arrangements) supports farmers’ adoption of good agricultural practices. We first explored the drivers of farmer sales to different market channels using a multinomial logit model. Then, using multivariate probit analysis, we identified factors associated with the adoption of good agricultural practices (GAP) and good handling practices (GHP) with particular attention to a farmers’ market channel. We found that larger smallholder farmers using modern irrigation are more likely to sell to midstream actors. We also found that selling to wholesalers and aggregators is an important determinant of farmers’ adoption of GAP and GHP, and this holds even for the smallest smallholder farmers. These results confirm that even where informal trading arrangements dominate (as is common in most LMICs), value chain actors in the midstream of food supply chains can support farmer adoption of GAP and GHP. These relationships have important implications for food security via enhancing the livelihoods of smallholder producers and improving the availability and safety of fresh produce for consumers, and thus should be leveraged in the design and implementation of efforts to expand farmer adoption of GAP and GHP.

Essential commodities prices, availability, and market actors’ perceptions: December 2025

Merchants’ expectations remained broadly stable in December. About 62.5 percent planned to continue trading at current levels, similar to November. However, the share intending to expand trading volumes declined to 20.6 percent from 26.7 percent, with planned expansions mainly concentrated in Blue Nile and South Kordofan. Only small shares of merchants planned to reduce trade volumes (4.4 percent, mainly in Gedaref and North Kordofan) or relocate to other markets (around 4 percent, notably in South Kordofan and Kassala). Temporary exits from trading or changes in product mix were negligible, while uncertainty about future plans increased to 6.6 percent, up from 3.5 percent in November.

Impact of Climate Change on Cost and Cost Efficiency of Solar Irrigation in Sub-Saharan Africa

Synopsis: Implications of urbanization, consumer awareness, and income trends on future food supplies in Senegal

Our food systems (FS) are unable to provide healthy diets in a just and sustainable way, an observation which prompted the United Nations Food Systems Summit to establish a consensus on the need to transform FS. This study examines potential entry points—and resulting implications—to improve Senegal’s FS following expected trends in population growth and urbanization, consumer awareness, and income growth. The study finds that total food supplies need to triple by 2040, with animal-source foods (ASF), fruits, and vegetables requiring increases of a factor of four or more. The study identifies potential strategies to increase the production of these food products while also considering their environmental impact. The study underscores the importance of socially inclusive and equitable outcomes and highlights the need for significant investments to reduce food waste in targeted subsectors.

Using small-object detection to track solar irrigation scaling: Opportunities and limitations

In this study, we pilot a workflow in Fayoum, Egypt, using freely available high-resolution imagery and an iteratively expanded, custom-labeled dataset, to explore whether small-object detection can feasibly track solar-powered irrigation adoption. If feasible, this approach can provide a low-cost, scalable foundation for evidence-based policy. Beyond mapping adoption, the method also has potential to link solar irrigation detection to environmental and agricultural outcomes, such as vegetation dynamics, cropping intensity, or water use efficiency.

Network effects in household consumption patterns: Evidence from northern Ghana

We study peer effects in consumption patterns and their associated welfare implications among rural farm households in northern Ghana using a panel data set. We construct a social interaction network based on household-specific locations and employ a spatial econometric approach that leverages the structure of the peer networks to identify peer effects. The results indicate that peers’ consumption patterns significantly influence individual consumption decisions, with the magnitude of this effect varying across farm households depending on their resource endowments. We also find that information exchange and partial risk-sharing behaviors drive these peer effects. Overall, our findings suggest that government interventions aimed at enhancing household consumption through transfers would be more effective if targeted at households with relatively large peer networks. In addition, anti-poverty and income-improvement programs can leverage peer networks to enhance their overall impact.

Learning effects of an experiential groundwater resource game in north-eastern Ghana

The growth of dry season farming in Ghana is putting increased pressure on groundwater resources. Using mixed methods this paper examines the learning effect of an experiential groundwater resource game in Ghana’s Upper East Region that simulates real-life resource use and common-pool resource management dilemmas. Results indicate short and medium-term learnings associated with participation in the game. During the game, group interaction and communication improved cooperation and led to more sustainable game behaviours. The gender-specific analysis indicates that females and males may learn and respond differently to the game. Males exhibited more sustainable game behaviours with increased communication and rules whereas female groups showed more learning from round to round. The positive learning effects from the game persisted 12 months after the intervention. Debriefing and focus group participants mentioned lessons learned about the depletable and shared nature of groundwater resources and the importance of communication and collective governance. Participants also described selecting water conserving crops and creating community watering schedules to manage water use. Findings highlight the important role experiential learning games can play in increasing knowledge, motivation, and agency associated with sustainable natural resource use.

Can a light-touch graduation model enhance livelihood outcomes? Evidence from Ethiopia

Associations between Global Diet Quality Score (GDQS) and obesity in women of reproductive age in Northern Tanzania: A cross-sectional study

Background
Obesity is an increasing problem among women of reproductive age (WRA) in Tanzania.

Objective
We described WRA’s nutritional status by socio-demographic factors and assessed associations with diet quality.

Methods
We analysed baseline data from a cluster-randomised controlled trial in Arusha and Kilimanjaro regions (n=2,415). Diet was assessed using a quantitative 24-hour recall. We calculated the Global Diet Quality Score (GDQS; 0-49), with higher scores indicating healthier diet. General obesity was defined as body mass index (BMI)≥30 kg/m2; morbid obesity as BMI≥35 kg/m2; and central obesity as: waist circumference (WC)≥80 cm, WC≥88 cm, waist-to-hip ratio (WHR)≥0.85, waist-to-height ratio (WHtR)≥0.50, and WHR≥0.85 or BMI≥30 kg/m2. We tested associations between diet quality and nutritional status using generalised linear models controlling for age and sociodemographic factors and tested interactions to assess differential associations by age groups.

Results
The prevalence of general obesity was 25.1%, morbid obesity 8.4%, and central obesity 48.2-71.6% depending on the definition. Mean GDQS was 20.9±3.9. General and central obesity were more prevalent among women who were older, less educated, had light physical labour occupations, were in the highest wealth quintile, and lived in more urbanised villages and in more food secure households. Higher GDQS was associated with lower risk of morbid obesity: risk ratio (RR) 0.97 (95% CI 0.94, 1.00). Higher GDQS was also associated with 0.25-0.27 kg/m2 lower BMI, 0.54-0.66 cm lower WC, and 0.53-0.58 cm lower hip circumference in women 30-49 years of age.

Conclusion
Better diet quality emerged as a protective factor for morbid obesity and for other obesity measures among women 30-49 years of age. Our study suggests that interventions to improve diet quality in Tanzania should target women in their thirties and forties and those with lower physical activity and higher education, food security, and wealth to maximise effectiveness.

Validity of the Diet Quality Questionnaire Compared with Observed Intake for Estimating Population-Level Diet Quality in Rwandan Adults

Background
The diet quality questionnaire (DQQ) is a standardized low-burden tool for collecting data on minimum dietary diversity for women (MDD-W) and other population-level diet quality indicators related to risk of noncommunicable disease (NCD). Although 24-h recalls (24hRs) are often used for evaluating validity of DQQ, they may underestimate consumption of specific food groups. Therefore, comparison with observed weighed food records (OWFR), can provide a more accurate assessment of DQQ criterion validity.
Objective
The aim of this study is to evaluate criterion validity of DQQ for estimating population-level diet quality using OWFR and 24hR as reference methods.
Methods
Cross-sectional data were collected among 281 Rwandan adults (Musanze district), using OWFR, DQQ, and 24hR on the same day. Diet quality indicators derived from each method were compared using parametric and nonparametric methods and the method of triads, which calculates pairwise validity coefficients to evaluate accuracy (low: <0.30; moderate: 0.30–0.70; high >0.70).
Results
Mean percent agreement in food group consumption data was high: 93% (DQQ-OWFR; DQQ-24hR). Compared with OWFR, DQQ overestimated MDD-W-prevalence [DQQ: 46.0% compared with OWFR: 40.4%; +6 percentage points (pp), P > 0.05], whereas using 24hR, the MDD-W-prevalence was 29.8% (16.2 pp < DQQ, P < 0.05, and 10.6 pp < OWFR, P < 0.05). Compared with OWFR, mean scores of food group diversity score (FGDS) and NCD-protect were 0.2 (ns) and 0.2 (P = 0.01) points higher by DQQ, respectively, and 0.4 (P < 0.001) points higher by DQQ compared with 24hR. NCD-risk median scores were 0 across methods. For DQQ, validity coefficients were 0.70 (FGDS), 0.67 (NCD-protect), and 0.66 (NCD-risk), compared with 0.93, 0.89, and 0.59 for OWFR, respectively, and 0.84, 0.83, and 0.98 for 24hR, respectively. Conclusions The DQQ showed high agreement with OWFR and 24hR for collecting population-level food group consumption data, and slight overestimations of diet quality indicator scores compared with observed intakes. DQQ is a valid and practical method for collecting population-level food group consumption data and estimating diet quality.

Understanding farmers’ adoption patterns of biofortified crops in Uganda: A case of iron beans

The diffusion of agricultural technologies, such as biofortified crops, is often non-linear, characterised by adoption, discontinuation, and re-adoption. This study examines the factors shaping these dynamic patterns for high-iron beans (HIBs) in Uganda. Based on cross-sectional survey data, we employed a multinomial logit model to categorise and analyse farmer adoption status. The results reveal that a combination of socio-economic and institutional factors significantly influences adoption behaviour. Specifically, the gender and age of the household head, as well as participation in off-farm income, were key socio-economic predictors. Regarding institutional factors, access to reliable markets and the presence of payback schemes emerged as the primary drivers. These findings suggest that overcoming adoption barriers requires addressing both the demographics of farmers and systemic constraints. We recommend a strategic pivot towards decentralising seed production by establishing certified community seed enterprises and enhancing training programmes that focus on both agronomic practices and market linkages to ensure the sustained cultivation of HIBs.

Outcome assessment of the digital agriculture ecosystem in Ethiopia

Ethiopia is making gradual but notable progress toward the digital transformation of its agricultural sector, driven by investments in connectivity, digital infrastructure, and cross-institutional coordination. Recent policy milestones have established an enabling foundation for scale, including the Digital Ethiopia 2025 and Digital Ethiopia 2030, personal data protection regulation and governance frameworks, and national roadmaps that will steer investment and implementation over the next decade—particularly the Digital Agriculture Extension and Advisory Services (DAEAS) roadmap and the Digital Agriculture Roadmap (DAR). However, persistent structural constraints such as limited rural internet coverage, low smartphone penetration, and unreliable electricity continue to shape the pace and equity of adoption. This paper synthesizes Ethiopia’s digital agriculture ecosystem with a focus on technology, data and analytical capacity, and policy environment. In the technology landscape, work is ongoing to develop decision-support applications alongside digital channels for delivering advisory services. Evidence from multiple pilot initiatives suggests these tools can expand outreach cost-effectively and improve the timeliness and relevance of agronomic guidance. The success of various pilot projects, along with valuable lessons from earlier efforts, strong government commitment, and supportive policies, has driven further investment in Ethiopia’s digital ecosystem. Nonetheless, substantial gaps remain in data availability and quality that limits the production of high-quality and context-specific advisory content. In addition, the reach and intensity of extension services needed to translate digital innovation into sustained productivity gains, income and livelihoods is not yet at the level desired. While Ethiopia’s digital agriculture agenda is well-positioned for accelerated scale, its impact will depend on resolving foundational constraints in last-mile connectivity, power reliability, and the institutions and pipelines required for trustworthy data and localized advisory at national scale.

IFPRI Malawi maize market report, December 2025

Retail prices of maize remained unusually stabile in December, when prices typically rise. Retail prices were stabilized by sustained informal imports at stable prices.

Synopsis: Economywide assessment of CSA interventions in building resilient agri-food systems in Rwanda

This research extends IFPRI’s RIAPA modeling to include both the full implementation of PSTA 5’s climate smart agriculture and a once-in-five-year weather shock, and the interactions of both on agricultural sectors, agricultural GDP, and on national GDP. Main findings include:

Rwanda’s agri-food system is highly vulnerable to climate variability due to its structural characteristics.

Results indicate that CSA practices during the PSTA-5 period (2024/25–2028/29) increase agricultural GDP growth by 0.9 percentage points annually, with the largest impacts on horticulture and roots and tubers. However, several CSA interventions relate to infrastructural improvements and therefore the benefits extend over a longer time horizon, ultimately having even greater impact beyond PSTA 5.

The weather shock causes dramatic declines in agricultural GDP (-1.6 percent), with horticulture affected most negatively, suffering a 2.4 percent decline.

The joint Climate + CSA scenario depicts how CSA helps mitigate, but not fully eliminate, the negative impacts of weather shocks during the PSTA 5 period.

Sudan prices and availability monitoring survey (SPAMS): Methodology, coverage, and value addition

Sudan is facing profound economic and market disruptions driven by prolonged conflict, political instability, and severe macroeconomic deterioration. These shocks have substantially undermined agricultural production, disrupted supply chains, and weakened market functioning across the country. Agriculture, which remains central to livelihoods, food security, and economic activity in Sudan, has been particularly affected by infrastructure damage, population displacement, rising input and transport costs, and increasing fragmentation of markets. In this context, food availability and affordability have become highly volatile, with wide spatial disparities across states and localities.

The effect of teacher training and community literacy programming on teacher and student outcomes

Motivated by extremely low levels of basic reading skills in sub-Saharan Africa, we experimentally evaluate two interventions designed to enhance students’ early-grade literacy performance in rural Mozambique: a relatively light-touch, scalable teacher training in early-grade literacy including the provision of pedagogical materials, and teacher training and materials in conjunction with community-level reading camps. Using data from 1,596 third graders in 160 rural public primary schools, we find no evidence that either intervention improved teachers’ pedagogical knowledge or practices or student or teacher attendance following two years of implementation. There are some weak positive effects on student reading as measured by a literacy assessment, primarily observed in a shift away from scores of zero, and these effects are consistent across arms. Our findings are aligned with the growing consensus that more intensive school- and/or community-based interventions are required to meaningfully improve learning.

Agricultural technology adoption and deforestation: Evidence from a randomized control trial

We study the effect of the adoption of improved agricultural inputs on deforestation using a randomized control trial in Nigeria which introduced a more efficient and environmentally-friendly nitrogen fertilizer. We combine survey data from the intervention with earth observation data to develop a generalizable method for evaluating the effects of cluster-level interventions on landscape-level outcomes. We find evidence of an intensification response to treatment exposure that reflects significant heterogeneity across land cover. On land with relatively sparse pre-intervention tree cover, treatment exposure increased deforestation while in denser forest areas the intervention reduced deforestation. We find corresponding effects showing treatment exposure increases agricultural productivity. Our results reflect an intensification response to improved agricultural technology that redirects agricultural activity away from forests and towards existing cropland.

Transfers, information and management advice: Direct effects and complementarities in Malawi

We examine a program designed to alleviate credit, information, and farm management constraints among smallholder cash crop farmers through transfers and a cross-randomized program offering intensive agricultural extension. We document strong complementarities between the two sets of interventions. Investment driven by increased labor expenditures, production, and consumption are highest for farmers that received both transfers and intensive extension, a pattern that persists two and three years later. In the short run, transfers alone led to the reallocation of input expenditures into increased labor for cash crop cultivation, which led to increased production of project focal crops but not total crop production. While farmers in the transfers only group continue to spend more on labor in subsequent seasons, this does not lead to changes in production or consumption, suggesting that the support of the intensive extension was important for the generation of the largest welfare gains from the transfers.

Increasing women’s empowerment: Evaluating two interventions in Uganda

We conduct a randomized controlled trial to test a novel intervention for increasing women’s empowerment in Uganda. The intervention includes a within-household transfer of a productive asset, which has a lower cost than an external transfer. We find that transferring control of some of the household’s sugarcane to the wife significantly increases her access to resources and decision-making power. We also document increases in women’s empowerment arising from a cross-randomized couples’ workshop that improved women’s self-concept and shifted beliefs in gender equality. We find no additional impacts from combining the two interventions. Importantly, neither intervention harms the household’s productivity or husbands’ welfare. In fact, men (and women) report higher marital quality and life satisfaction as a result. However, despite increasing women’s empowerment we find no evidence that the interventions increased measured household investment in food security, child health, or education.

Constraints and promising interventions to strengthen fish seed systems in Sub-Saharan Africa: Evidence from Ghana

CONTEXT
Aquaculture has surpassed capture fisheries in terms of production and is among the fastest growing food sectors. It has great potential to contribute to food security and nutrition, poverty reduction, jobs, and environmental sustainability. Fish seed is increasingly considered to be a major driver and disabler of aquaculture development. However, little is known about how fish seed systems operate, their challenges and opportunities, or entry points for strengthening them.
OBJECTIVE
This study analyzes primary data on the challenges and opportunities faced by various actors along the fish seed chain, documents the lessons from a fish seed project (Ghana Tilapia Seed Project, 2019–2022), and provides an analysis of entry points for strengthening fish seed systems.
METHODS
Using an analytical framework that tracks germplasm base, seed production and quality, seed availability and distribution, and the information flow along the fish seed value chain, we analyze the case of Ghana, the top producer of farmed tilapia in sub-Saharan Africa. The study uses a mixed-methods approach, including value chain analysis, action-oriented research methods, and statistical analysis of survey data.
RESULTS AND CONCLUSIONS
Findings indicate that the initial rapid growth in tilapia production in Ghana was partly due to an improved local strain released in 2004; however, the recent stagnation is largely caused by seed-related issues (poor maintenance and improvement of germplasm base, seed quality and availability, lack of information and coordination, and lack of enforcement of regulations). This study highlights the successes and lessons learned from the Ghana Tilapia Seed Project on broodstock distribution, training on fingerling production, establishment of nurseries, and training of fish farmers. The lessons highlight the need for policy changes and capacity building related to strain development and broodstock management.
SIGNIFICANCE
These findings fill the large gap in evidence on the functioning of fish seed systems and how to strengthen them. They can directly inform ongoing country-level efforts and programs aiming to develop aquaculture.

Estimating multidimensional development resilience

Existing measures of resilience are typically based on a single well-being indicator. This is problematic in contexts where households face deprivations across multiple dimensions. We develop a multidimensional resilience measure, integrating probabilistic moment-based resilience measurement approaches with multidimensional poverty measurement methods. Applying these to household panel data from Ethiopia, we show that univariate and multidimensional resilience measures based on expenditure-based poverty, dietary diversity, and livestock asset holdings can yield varied inferences on the ranking of households as well as potential impact of development interventions. Univariate resilience measures constructed using consumption expenditure, dietary diversity and livestock asset holdings show distinct temporal and spatial distributional patterns. But while univariate measures are weakly correlated with one another and with different well-being metrics, multivariate measures exhibit much stronger rank correlations. When we contrast univariate measures of resilience to multidimensional measures of resilience, we find that the latter vary less over the study period; multidimensional resilience measures seem to capture more “persistent or structural” vulnerability and associated capacity of households. We also demonstrate the differences in these univariate and multivariate measures, including the potential of the composite multidimensional resilience measures for supporting targeting processes.

Using best-worst scaling to inform agroecological interventions in Western Kenya

Both the demand for food and the environmental impacts of food production are estimated to significantly increase by 2050. Agroecological interventions have proven effective in facilitating the transition from current food production systems to more sustainable ones. These interventions can not only ensure more equitable food and nutritional security but also address poverty and reduce environmental impacts. As such, agroecological interventions can generate both private and public ecosystem services. Farmers play a key role in how food is produced, as the practices they use are linked with their preferences and expertise, as well as the constraints they face. Understanding farmers’ preferences for the adoption of different agroecological practices and their perceptions of the associated costs and benefits is critical to informing policies that can effectively support farmers in transitioning to more sustainable practices, including those that contribute to the generation of ecosystem services highly valued by broader society. To assess such preferences, we conducted a survey among farmers in Western Kenya which included a best-worst scaling experiment augmented by qualitative questions about the reasons for farmers’ views about the importance of the benefits arising from agroecological practices. Results show that farmers have strong preferences for adopting agroecological practices that generate private goods and are directly related to increasing productivity and food security, including improving health of household members. These may also include practices that have some public good elements as well, such as increasing agrobiodiversity. However, practices that generate broader public good benefits, including improved forest quality/coverage, reduced off-farm environmental impacts, greater community-level resilience to shocks, and improved landscape and wildlife management, were less important to farmers. Such findings can be used to inform policies that support farmer adoption of agroecological interventions best suited to different farming communities, as well as indicating the need for additional types of market-based incentives, such as through Payments for Ecosystem Service mechanisms.

Promoting regional income equity under structural transformation and climate change: An economywide analysis for Senegal

Representation increases women’s influence in climate deliberations: Evidence from community-managed forests in Malawi

Women’s inclusion is now the norm in global and local initiatives to combat climate change. We examine how women’s representation affects climate deliberations using the case of community-managed forests in Malawi. We run a lab-in-the-field experiment randomly varying the gender composition of six-member groups asked to deliberate on policies to combat local overharvesting. We find that any given woman has relatively more influence in group deliberations when women make up a larger share of the group, a change driven by men’s assessments of women’s influence. Women’s presence also shifts the content of deliberations toward prospective solutions for which women have socially recognized expertise (cooking and replanting). Despite these changes, women and men do not prefer different deforestation policies, and women’s presence does not meaningfully affect group decisions. Our work demonstrates how women’s presence shapes climate deliberations but also calls into question claims that women’s inclusion will necessarily affect climate decisions.

Rural land rental markets in developing countries: Can survey design innovations improve land market participation statistics?

A longstanding puzzle in the African land rental market literature is the often-observed discrepancy between the number of tenants (renters-in) and the much smaller number of landlords (renters-out) in survey data. If this discrepancy derives from systematic biases in survey data responses on rental market participation, then the existing body of survey-based empirical work on land rental markets impacts may be fundamentally flawed. To examine this issue, we implemented two survey experiments. First, we tested the hypothesis that some categories of rented land are underreported because enumerators and respondents focus primarily on parcels directly managed or cultivated by the household. A random subset of respondents received a priming nudge reminding them to account for all land, including rented- or sharecropped-in and rented- or sharecropped-out parcels. Second, we tested whether households underreport rented- or sharecropped-out land due to reluctance to disclose activities that may carry social or institutional repercussions, using a double-list experiment to infer true rates of participation. Interestingly, our results indicate a significant underreporting of both renting-in and renting-out land but arising through different mechanisms. The priming nudge increased reports of renting-/sharecropping-in by 4 percentage points (equivalent to 13% of landlords in the sample) but had negligible effects on reported renting-/sharecropping-out. By contrast, the list experiment suggests that the true share of renting-out households is about 15%: much higher than the 3% in parcel-roster responses. These results underscore the need for improved survey methods to accurately observe land rental market participation and evaluate its impact.

Innovation environment and entrepreneurial intentions among undergraduate students in Nigeria: The moderating role of entrepreneurial education

Basis risk, social comparison, perceptions of fairness, and demand for insurance: A field experiment in Ethiopia

Index insurance lowers agricultural risk but covers only covariate risks. Since farmers do not have complete insurance, they may develop mistrust of insurance when experiencing crop losses and not receiving payouts. Although recent innovations in remote sensing enable the provision of more complete insurance including coverage for idiosyncratic risks, such insurance introduces differences in payouts within social networks, which might be considered unfair, introduce jealousy, and depress insurance demand. We conduct a lab-in-the-field experiment with farmers in Ethiopia to examine whether providing complete insurance coverage affects perceived fairness and insurance demand. We also examine effects of informing farmers about neighbors’ payout experiences. We find that such social comparison increases perceived fairness of index insurance. Providing complete crop insurance increases perceived fairness of outcomes and willingness to pay for insurance, without introducing jealousy over neighbors receiving different payouts.

Buyers’ response to third-party quality certification: Theory and evidence from Ethiopian wheat traders

When quality attributes of a product are not directly observable, third-party certification (TPC) enables buyers to distinguish between quality levels and reward sellers accordingly. We study the adoption of TPC by traders in smallholder-based agricultural value chains in low-income countries, where traders aggregate products from many small-scale producers before selling in bulk to downstream processors. In this context, the introduction of TPC services has oftentimes failed. We develop a theoretical model identifying how different market conditions affect traders’ choice to purchase certified output from farmers. Next, using a novel lab-in-the-field experiment with Ethiopian wheat traders, we examine the model’s predictions. Traders’ willingness to specialize in certified output increases with the share of certified wheat in the market, and this effect is stronger in larger markets. However, we find that traders do not optimally respond to variation in the quality of uncertified wheat in the market. We also analyze conditions where traders deviate from optimal behavior and discuss implications for research and policy making to promote TPC in smallholder-based value-chains.

The economic costs of bribes and road harassment by officials in ECOWAS

The effect of using indigenous and scientific forecasts on arable farmers’ crop yields: Evidence from Rwenzori region, western Uganda

What are the economic and poverty implications for Sudan if the conflict continues through 2025?

The ongoing conflict in Sudan, which began in April 2023, has triggered severe economic contractions, exacerbating poverty and unemployment while disrupting key sectors of the economy. This study employs an updated economywide database to assess the economic impact of a continued conflict through the end of 2025 under two scenarios of extreme and moderate contractions in the overall GDP. Our findings indicate that by the end of 2025, Sudan’s GDP would decline by 42% under the extreme scenario and 32% under the moderate scenario. The agrifood system would be particularly affected, with its GDP contracting by 33.6% and employment halving under the extreme scenario. Household incomes decline across all quintiles, with rural populations and women experiencing the sharpest losses. The national poverty rate is projected to rise by 19 percentage points under the extreme scenario, further deepening socioeconomic vulnerabilities. To mitigate the widespread adverse impacts of the conflict on the Sudanese economy, policies and interventions should prioritize the restoration of economic productivity, support the agrifood system and employment recovery strategies, and ensure that social protection measures are accessible to all households facing increased deprivation.

Capacity development needs and roadmap

This report integrates an assessment of institutional readiness for Earth observation (EO)-based crop monitoring in Mozambique with a roadmap for sustaining and scaling an EO and digital workflow for agricultural statistics. The aim is to:
Baseline current capacity by systematically evaluating the institutional readiness and willingness within key government organizations to adopt and sustain EO-based systems.
Identify gaps and risks by pinpointing specific challenges, from technical shortages to policy misalignments, that could prevent the sustained adoption of EO technology beyond a project’s life cycle.
Document actions to maintain or raise the institutional readiness level to ensure the project’s desired impact is feasible.

The narrative focuses on what would be required to move from project demonstration to routine production and use, with the Ministério da Agricultura, Ambiente e Pescas (MAAP, formerly the Ministry of Agriculture and Rural Development, MADER) and the Regional Centre of Excellence in Agrifood Systems and Nutrition (CE-AFSN) at Universidade Eduardo Mondlane (UEM, formerly the Centro de Estudo de Políticas e Programas Agroalimentares, CEPPAG) as the main national counterparts and with due recognition of the role of the Instituto Nacional de Estatística (INE).

The readiness assessment highlights that Mozambique has strong potential for EO-enabled agricultural data, but that this potential is constrained by fragmented technical capacity, limited government resourcing for software and computing, a reliance on short-term projects and external consultants, and weak institutional arrangements for data ownership, openness, and inter-agency collaboration. It also identifies governance risks created by outdated foundational baselines that continue to shape policy and sampling design.

The roadmap therefore centres on a staged transition. In the near term, priority lies in formalising mandates, custodianship, documentation, and integration pathways with existing survey and census processes. In the medium term, priority lies in building repeatable operational capability and reducing dependence on a small number of individuals. In the longer term, priority lies in embedding stewardship and financing, updating national baselines on a defined cycle, and using the donor-led Development Partners Group for Agriculture and Rural Development (AgRED) group as a coordination mechanism to align partner support and reduce duplication.

Assessing the development impacts of bio-innovations: The case of genetically modified maize and cassava in Tanzania

Youth in relation to agroecology: practices, promises, and perceptions in five countries

In the context of rising youth populations in many low- and middle-income countries, coupled with high youth unemployment and aging farmer populations, this paper asks in what ways agroecology, as a sustainable alternative to the conventional agricultural practices and paradigm, attracts youth to farming and rural-based livelihoods. We draw on empirical data from semi-structured interviews and photovoice conducted with young women and men in five countries: Kenya, India, Peru, Tunisia, and Zimbabwe. In our discussion, we highlight which dimensions and aspects of agroecology resonate with youth and why.

Moving the technology frontiers in African agrifood systems: An analytical framework

The transformation of African agrifood systems stands as one of the most urgent and complex development challenges of the 21st century. With over 60 percent of the continent’s population relying on agriculture for their livelihoods, the sector holds tremendous potential to serve as a catalyst for broad-based economic growth, poverty alleviation, and food and nutrition security. This potential, however, remains largely untapped. Agricultural productivity across Sub-Saharan Africa (SSA) continues to stagnate; despite decades of reform efforts and policy commitments, it lags significantly behind other regions of the world (Ulimwengu et al. 2025).

Moving the technology frontiers in African agrifood systems: Lessons from Latin America

Africa’s agrifood systems face a complex set of structural challenges. Low productivity, high vulnerability to climate shocks, fragmented markets, and weak integration into global value chains continue to constrain development. Yet these challenges coexist with significant opportunities. The region’s demographic profile—with more than 50 percent of the population under the age of 25 years—and a projected population growth rate of 2.3 percent in 2025 offer the potential for a demographic dividend that could help drive transformation in agri-food systems.

Advancing mechanization in African agrifood systems: Unlocking productivity and resilience

This chapter examines the role of mechanization in transforming African agrifood systems within the broader discourse on technological change, structural transformation, and sustainable development. The motivation is to address the persistent challenges of low productivity, rural poverty, labor shortages, and vulnerability to climate change that continue to constrain the agricultural sector across the continent.

Evaluating large-scale government investments in fertilizer adoption: The Ethiopian experience

We evaluate the impact of a large Government of Ethiopia intervention to raise fertilizer supply by establishing five fertilizer blending facilities supplying fertilizers tailored to local soil nutrient profiles. We rely on the phased geographic rollout of blending facility establishment to identify the causal effect on fertilizer use, application rates, crop yields, gross crop revenue, and household consumption. Combining effects of multiple treatment periods, each estimated using a doubly robust difference-in-difference model, we find that the blending facilities increased the probability that farmers adopt the new blended fertilizers by 22 percentage points and increased application rates by 17 kg/ha (baseline adoption was zero). The facilities mostly induced farmers who previously used DAP to switch to NPS, and we find large decreases in DAP adoption (by 22 percentage points, 47% of the control group base mean) and application rates (16 kg/ha, 52% of the control group base mean) yet no impact on overall fertilizer adoption or application rates. Though the new blended fertilizers were expected to perform better, there is no evidence they improved crop yields, crop gross revenue, or household consumption. The effect of the intervention was more pronounced (with larger increases in NPS use and larger decreases in DAP use) for farms located near demonstration plots, which the Government used to train farmers about the agronomic response to the new fertilizers. We confirm results using three large-scale longitudinal datasets and show that they are robust to choices of specification, treatment definition, and inference assumptions.

Effects of home production for home consumption on semi-subsistence economies

Exploring relationship pathways to prevent intimate partner violence among young women in Malawi

International estimates of intimate partner violence (IPV) among adolescents and young women are high, indicating the need to address IPV prevention early in life. Structural economic interventions, such as household cash transfer programmes, have the potential to improve the wellbeing of youth who are not the direct recipients of the transfers themselves. However, few studies have addressed this topic in terms of youth romantic and/or sexual relationships. We conducted 39 in-depth interviews with young women aged 19-29 years in households participating in the Government of Malawi’s Social Cash Transfer Programme (SCTP) to examine relationship formation, IPV triggers and experiences, and help-seeking behaviours. We found that young women did not directly attribute SCTP effects to their intimate relationships or IPV experiences. Threats to masculinity and transgressions of women’s gender norms were key triggers of IPV, but specific triggers were linked to specific types of IPV. Furthermore, women sought help for non-IPV concerns more than IPV-related issues. Our results reveal there is a need to strengthen cash transfer programmes and layer them with tailored interventions for adolescents and young women in participant households to improve relationships and prevent IPV early in life.

Intervening in complex food systems: How outcome mapping of multi-actor platforms traces change in central Mozambique

Purpose:
Agricultural Innovation Platforms (AIPs) are increasingly applied by advisory services as approaches to facilitate learning and co-create food system solutions. However, the outcomes of such processes are rarely documented. In this study, we present an approach for capturing process outcomes and share findings from applying the approach to an AIP in central Mozambique.

Design/methodology/approach:
We complemented propensity score matching with regression adjustments and incorporated outcome harvesting as a participatory, retrospective evaluation method.

Findings:
We find that the AIP led to the formation and registration of a farmer association. This improved self-organisation and fostered ownership among participants in driving systemic change and generated spillover effects to farmers who were not directly involved in the process. Moreover, AIP members reported adopting improved agricultural practices compared with the control group.

Practical implications:
Our study highlights the challenges of providing evidence for outcomes and offers ways to address some of them. The proposed approach can support future AIP initiatives in embedding the documentation of process outcomes into the implementation process.

Theoretical implications:
Our research reaffirms that improving food systems requires integrated approaches that address multiple components of the system while accounting for trade-offs and synergies. To capture changes across these components, research designs need to be flexible and employ multiple methods.

Originality/value:
Strengthening this evidence base on the impacts and outcomes of AIP processes is essential for refining the approach and increasing the confidence of extension agents in applying AIPs at a larger scale.

Assessing the role of food MSMEs in providing employment for women and youth in Ethiopia

Micro-, Small-, and Medium-Sized Enterprises (MSMEs) are often important sources of employment in the food retail environment of Low- and Middle-Income Countries. As a result, policy makers might consider promoting job creation through MSMEs operating in the food environment. In this paper, we study a unique data set collected in two sites in Ethiopia to draw potential policy lessons for job creation based on the characteristics of MSMEs operating in the food environment. The data were collected from among 1,686 food vendors in a neighborhood of Addis Ababa and Butajira, Ethiopia, as part of an effort to better understand the relationship between consumers and the food environment in Ethiopia. Our descriptive analysis suggests that a large share of the enterprises in our sample do not employ anyone beyond the owner, and female-owned enterprises are less likely to hire workers than male-owned enterprises. Moreover, the profits per worker are lower than the cost of a healthy diet, suggesting that without an improvement in profitability it is unlikely that hiring labor would help improve nutritional status. So while the sampled MSMEs may have the potential to deliver food at lower cost, they have limited ability to generate additional employment.

Seeds of change: The impact of Ethiopia’s direct seed marketing approach on smallholders’ seed purchases and productivity

While multiple factors explain low adoption rates of improved varieties by small-scale farmers in sub-Saharan Africa, a key supply-side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market for seeds and traits. Historically, governments have remedied this failure by allocating public resources to varietal improvement and seed distribution. In 2011, the Government of Ethiopia launched a novel experiment—the direct seed marketing approach—to encourage private seed investment in the country’s seed system and to reduce the state’s footprint in the system. Direct seed marketing incentivized seed companies to sell directly to farmers rather than through state distribution channels. This study provides the first quantitative assessment of the impact of direct seed marketing based on key indicators of a robust seed system: access to seed and farm-level productivity. Using a quasi-experimental difference-in-differences approach suitable to handling variation in treatment timing, we find that direct seed marketing increased the share of farmers purchasing fresh maize seed by 15 percentage points. It also raised the quantity of maize seed purchased by 45% and improved maize yields by 18%. In contrast, direct seed marketing had no effect on wheat seed purchases and yields. These crop-specific differences likely reflect underlying differences in the reproductive biology of maize and wheat, highlighting the importance of crop-specific policy design, institutional arrangements, and market development strategies to accelerate the adoption of improved varieties.

Under the gun: Military and paramilitary actors in Sudan’s agrifood system

Armed actors are entrenched in the agrifood systems of several low- and middle-income countries, often with implications for agricultural transformation and democratic transitions. This paper focuses on the Sudanese Armed Forces (SAF) and Rapid Support Forces (RSF) in Sudan’s agrifood system. Through over 50 semi-structured stakeholder interviews, the paper traces how these actors gained their foothold in the agrifood system and how they interact with the private sector across diverse value chains. We argue that their investments in certain value chains depend on whether the formal private sector is already involved and the degree of technical complexity required for more profitable product upgrading. Based on these considerations, we uncover four strategies used in different value chains: exclusive capture and rent-extraction, biased competition through licencing and quota allocations, acquiescence to private competitors when value-addition is too complex, and innovation when profit potential is high and the private sector is absent. We demonstrate these strategies with respect to livestock, wheat, gum Arabic, and horticulture, with secondary applications to other commodities. Since economic competition between SAF and RSF was a major factor in the outbreak of the 2023-armed conflict, identifying these strategies expands insights about the political economy antecedents of large-scale conflict.

The impact of public price information on farm incomes: Lessons from the Ethiopian Commodity Exchange

Modeling crop-livestock interactions in semi-subsistence economies

Climate and weather shocks pose significant threats to crop and livestock systems, leading to economic losses and humanitarian crises. Utilizing a modeling framework that innovatively integrates the crop and livestock production systems in semi-subsistence economies, this study examines the interactions and dynamic adjustments within these systems following weather shocks, using Ethiopia as a case study. We also evaluate the effectiveness of various adaptation strategies in sustaining farm incomes, food security, and welfare. Results show unique effects on the crop and livestock sectors resulting from a joint shock on the two systems. While food crops experience a strong and immediate growth effect (12.4%) that fades quickly, the livestock sector faces the full impact of the shock a year later (13.7%), with the effect persisting to some degree. We also find diverging economic and livestock system adjustment trajectories from separate shocks to the crop and livestock systems. Further, the intervention options analyzed show contrasting impacts on various outcome indicators, with only the resilient crop intervention causing sector-indifferent impacts. Our findings emphasize the importance of proactive measures to enhance the resilience of crop-livestock systems, with implications for policy and practice aimed at safeguarding food security and livelihoods in semi-subsistence economies.

Digital health interventions in strengthening primary healthcare systems in Sub-Saharan Africa: Insights from Ethiopia, Ghana, and Zimbabwe

Digital Health Interventions (DHIs) refer to discrete technological functionalities designed to achieve specific objectives in addressing health system challenges. These interventions are considered tools for strengthening health systems, particularly in low- and middle-income countries. This study consolidates findings from Ethiopia, Ghana, and Zimbabwe, examining how three distinct digital health applications with varying intervention components implemented in primary healthcare settings contribute to health system strengthening. The interventions analyzed include Ethiopia’s District Health Information System 2 (DHIS2), Ghana’s District Health Information Management System (DHIMS) and the Lightwave Health Information Management System (LHIMS), and Zimbabwe’s Impilo Electronic Health Record (E-HR) system. In Ethiopia, DHIS2 enhanced health system accountability and data quality by streamlining district-level data aggregation, reporting, and performance monitoring. This led to more informed decision-making and improved resource distribution. In Ghana, DHIMSs functions as a public health-level DHI, facilitating national data-driven performance monitoring, while LHIMS operates at the patient level, supporting patient tracking and management, improving patient workflows and resource tracking. However, a lack of interoperability between these two systems has led to data duplication challenges. Zimbabwe’s Impilo E-HR, a patient-level DHI, has streamlined clinical workflows, improved information sharing, and enhanced decision-making at the point of care. Despite these successes, challenges persist across the three contexts: infrastructure limitations, high staff turnover, and insufficient user technical capacity. Interoperability issues, particularly in Ghana and Ethiopia, hinder seamless data exchange, while sustainability concerns such as funding gaps and inadequate government support undermine the systems’ full potential. The study findings demonstrate that investments in DHIs in primary healthcare may not result in health systems strengthening without addressing baseline conditions for their implementation and sustainability.

The future in mind: Aspirations and long-term outcomes in rural Ethiopia

“If you want to have sex you can, if you don’t, you don’t have to”: A qualitative evaluation of the Unite for a Better Life couples program to prevent intimate partner violence in rural Ethiopia

Background
Gender-transformative programing targeting couples is an important strategy to reduce intimate partner violence (IPV), but questions around efficacy and safety remain. This qualitative study explores indications of change and unintended consequences of the gender-transformative Unite for a Better Life (UBL) intervention, using data from the couples’ and control arms of a cluster randomized controlled trial (cRCT) in Ethiopia. The cRCT found no impact on physical and psychological IPV and weak evidence of reductions in sexual IPV in the couples’ arm.

Methods
We analyzed 33 facilitator feedback questionnaires and 29 in-depth interviews (IDIs) among couples conducted approximately 30-months post intervention; 14 participated in UBL delivered to couples, and 15 were from the control arm. IDIs were conducted separately with each member of the couple and analyzed thematically in Dedoose to explore indications of change attributed to UBL.

Results
UBL couples attributed improved household task-sharing, communication, and joint decision-making to the program. Men and women developed more gender-equitable attitudes, leading to more fulfilling relationships. Additionally, most participants in violent relationships reported that UBL led to a reduction or cessation of physical and psychological IPV, and a complete cessation of sexual IPV. These effects were largely attributed to shifts at the individual level for men. Men developed better anger management skills, reduced their alcohol consumption, and increased their knowledge around the consequences of IPV. At the relational level, couples reported increased communication, particularly around sexual desire, and reduced conflict. Additionally, participants reported normative shifts, including decreased acceptance of IPV. There were no reports of changes in control participants nor of major unintended consequences.

Conclusions
When delivered to couples, UBL shows promise in shifting individual-level male factors and relational dynamics and reducing conflict and IPV. This suggests that engaging men in couples can be an effective and safe strategy for IPV prevention.

How do migrants fare in Africa’s urban labour markets?

Armed conflict and climate-induced weather disruptions in agricultural input use: Evidence From Ethiopia

Vouchers to increase fruit affordability in Nigeria and Vietnam

Although fruits are an important part of healthy diets, they are relatively expensive, so most individuals consume less than recommended. We use a randomized control trial to study a voucher program designed to improve the affordability of fruits in peri-urban and urban settings in Vietnam and Nigeria, and analyze whether vouchers can increase fruit consumption. The trial took place in 2021 among 601 households in Vietnam and 611 households in Nigeria. Vouchers were distributed between March and July in Vietnam and between June and November in Nigeria. In both contexts, a large majority of consumers who received vouchers used them. Following project conclusion, we find suggestive evidence of sustained increased fruit consumption only in Vietnam. In Nigeria, vouchers increased consumption of certain fruit categories during program implementation, but we find no evidence of sustained impacts. Fruit consumption is higher across the board in Vietnam, and the sample is wealthier overall, suggesting fruit affordability may not be a binding constraint for consumption. In Nigeria, the increase in consumption during the program along with a post-project decline suggest a lack of household resources to sustain consumption once the project concluded. The results suggest vouchers can improve consumption of healthy foods like fruits, but other actions are needed to make them more affordable in the longer term.

Unpacking the effects of conflict on fertilizer use and maize yields: Empirical evidence From Nigeria

Conventional recommendations emphasize increasing the use of inorganic fertilizer to enhance maize yields in African countries south of the Sahara, but it is not clear how smallholders’ exposure to violent conflicts affect demand, yield responses, and the profitability of fertilizers. Our study tackles this question. We analyze how maize yield responds to fertilizer use and assess the profitability of fertilizer use in conflict-affected settings. We then investigate how conflict impacts the profitability of fertilizer, given that armed conflicts are likely to increase input costs, logistical difficulties, and market uncertainties. Our study reveals that yield responses to nitrogen are very low in Nigeria. We also show that exposure to conflict reduces input use rates and decreases the marginal physical productivity of nitrogen in maize production, making investment in fertilizer less profitable. Recognizing this effect of conflict on input use and maize yield response is crucial for targeting and resource allocation decisions among smallholders in similar conflict-affected regions. Moreover, the effect of conflict highlights how external factors, beyond the scope of agronomic practices, influence the economic incentives for fertilizer application and the resulting yield outcomes.

Exposure and disease burden of fumonisins and aflatoxins from sorghum consumption in Ethiopia

Studies on mycotoxin exposure from sorghum consumption and related public health risk estimation are rarely available in Ethiopia. The aim of this research was to assess fumonisin and aflatoxin exposure of adults through sorghum consumption in the Amhara National Regional State (ANRS) and at national level in Ethiopia and to estimate related health risks. Data on fumonisin and aflatoxin concentrations in sorghum samples were collected from a survey and literature. Estimated fumonisin exposure in the ANRS and at national level were below the FAO/WHO limit of 2000 ng/kg bw day to be considered a health concern. The estimated aflatoxin exposure levels in the ANRS and at national level fall below the Margin of Exposure value of 10000, indicating potential health concern. The incidence of hepatocellular carcinoma due to aflatoxin exposure in the ANRS ranges from 0.0003 to 0.017 while at national level, it ranges from 0.181 to 8.47 (per100.000 persons/year). The related disability-adjusted life years estimates for the ANRS and at national level ranged from 0.0003 to 0.019 and 0.204 to 11.230, respectively. Aflatoxin exposures were driven more by sorghum intake than aflatoxin contamination. Dietary intervention could further reduce the health risk estimates.

Effect of combining lower- and higher-value monthly cash transfers with nutrition-sensitive agriculture, male engagement and psychosocial intervention on maternal depressive symptoms in rural Malawi: A secondary analysis of a cluster-randomised controlled trial

Maternal depression affects one in five women in Malawi. Integrated interventions simultaneously addressing multiple risks are a promising strategy to improve mental health. This study evaluated the impact of a nutrition-sensitive social behaviour change (SBC) intervention (agriculture and livelihoods, male engagement and Caring for the Caregiver) with or without cash transfers on maternal perinatal depression during the lean season in rural Malawi. A midline survey for a cluster-randomised controlled trial was conducted, where 156 clusters were randomly assigned to four arms (39 clusters/arm): (1) standard of care (SoC), (2) SBC, (3) SBC+low cash (US$17 per month) and (4) SBC+high cash (US$43 per month). Pregnant women and mothers of children <2 years of age (n=2677) were enrolled at baseline (May–June 2022). A subsample of 1303 women was followed-up at midline (November–December 2023). Maternal perinatal depression was assessed using the Self-Reporting Questionnaire with a score of ≥8 indicating symptoms consistent with depression. Intervention effects were estimated using linear mixed effects models. At midline, SBC+high cash reduced depression scores relative to SoC (mean difference −1.13 (95% CI −1.96 to –0.31)) but had no impact on the proportion of women with depressive symptoms. Relative to SoC, SBC+low cash and SBC alone had no impact on depression scores or the proportion of women with depressive symptoms. Relative to SBC alone, adding cash to SBC reduced depression scores and the proportion of women with depressive symptoms regardless of the size of the cash transfer. Cash transfers integrated with SBC can benefit maternal perinatal mental health in rural Malawi during the lean season.

Dietary intake and nutrient adequacies among women of reproductive age in northern Tanzania: A cross-sectional study

Background
Dietary inadequacies among women of reproductive age (WRA) increase malnutrition and disease risk.

Objectives
We characterized food group and nutrient inadequacies among WRA in rural Tanzania.

Methods
Baseline data (collected October 2023–January 2024) from a cluster-randomized controlled trial in Arusha and Kilimanjaro regions were analyzed. Dietary intake among WRA (n = 2594) was assessed using a 24-h dietary recall with the OpenDRS approach. This was repeated in a subsample (n = 520, 20%) to adjust for day-to-day variations in individual intake. The National Cancer Institute method was employed to estimate usual energy and nutrient intakes. Micronutrient adequacy was defined as intake greater than or equal to the harmonized average requirements (H-ARs). The mean probability of adequacy (MPA) was calculated as the average adequacy across 11 micronutrients.

Results
On average, women were 38.3 ± 6.2 y old; 19% were lactating, and 4% were pregnant. The mean daily energy intake was 2415 kcal/d [95% confidence interval (CI): 1937, 2895], with carbohydrates contributing 62% to daily energy intake. The mean intake of fruit and vegetables (F&V) was 279 g/d (95% CI: 201, 365), of which fruit was 35 g/d (95% CI: 2, 118) and vegetables 245 g/d (95% CI: 168, 328). Staples contributed half of the daily energy intake. About 1% of participants met calcium and vitamin B12 requirements, whereas 42%, 49%, 68%, and 72% met adequacy for vitamin C, folate, zinc, and iron, respectively. Most women met the H-ARs for riboflavin, niacin, thiamine, vitamin B6, and vitamin A. MPA was 65 (±2.3% standard error), with vegetables, pulses, animal-source foods (ASF), and staples being key micronutrient sources.

Conclusions
Substantial nutrient inadequacies exist among WRA in rural Northern Tanzania due to high cereal intake and low intake of F&V and ASF. Addressing these gaps requires targeted interventions, improved dietary diversity, increased intake of F&V and ASF, and enhanced food security through local production and social safety nets.

Food processing and nutrition in Africa: Improving diets under the Kampala Declaration

Africa’s food systems are undergoing rapid transformation, yet they remain burdened by a dual nutrition crisis: widespread undernutrition alongside rising obesity and diet-related non-communicable diseases (NCDs). Food processing stands at the intersection of this challenge—offering both risks and opportunities. This policy brief argues that when guided by nutrition-sensitive strategies, food processing can be harnessed to improve dietary quality, enhance food safety, reduce postharvest losses, and create economic opportunities, particularly for women- and youth-led enterprises. However, the proliferation of ultra-processed foods (UPFs) threatens to worsen public health outcomes unless appropriate regulation and consumer education accompany industrial growth. Drawing on evidence from the Malabo Montpellier Panel’s 2024 VALUE-UP report and innovative case studies across Africa, the brief recommends a multi-pronged approach: supporting fortified and minimally processed foods, strengthening small and medium-sized processing enterprises, advancing food safety systems, and investing in public-private partnerships for nutrition-focused innovation. Linking agrifood processing to better nutrition outcomes is essential to achieving the goals of the Kampala Declaration and the CAADP Strategy (2026–2035).

Understanding the evidence gaps: Diets and fruit and vegetable intake across five diverse low- and middle-income countries

Poor dietary quality, particularly inadequate fruit and vegetable (F&V) intake, remains a significant public health challenge globally. This article synthesizes findings from scoping reviews examining diet and F&V intake, and interventions to increase F&V consumption among population groups in five countries: Benin, Fiji, the Philippines, Sri Lanka and Tanzania. Our analysis confirms previous findings of inadequate F&V intake across all five countries, with most adults consuming well below the WHO recommendations of 400 g per day. Across the five countries, the identified scientific evidence is limited due to heterogeneous dietary assessment methods, limited coverage of population groups in national surveys and smaller studies, and limited data from rigorous evaluations of interventions aiming to increase F&V intake. Although all five countries have developed food-based dietary guidelines promoting F&V intake, research on their implementation and effectiveness remains limited. To build evidence for effective programmes and policies to improve both quantity and diversity of F&V intake, we identify three priority areas for future research: standardizing dietary assessment methods for use in surveys and evaluations, understanding context-specific drivers and determinants of F&V intake and strengthening intervention research in low-resource settings.
