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.

Optimizing school meals in Ghana: Integrating new food and nutrient standards with aspects of affordability, cultural acceptability and environmental sustainability

Objectives:
To optimize school food baskets in Ghana to meet newly proposed food and nutrition targets while considering cultural acceptability and cost.

Design:
Modeling study. Data on existing school meal menus was collected from various regions to provide baseline inputs. Linear programming (LP) was used to model school meal baskets that satisfied minimum nutrient and food targets for school meals while meeting cost and acceptability constraints. Five LP models were tested, each varying in budget constraints and acceptability/food-based parameters.

Results:
Baseline school food baskets were significantly deficient in energy, protein, iron, zinc, vitamin A, folate, vitamin B12 and vitamin C compared to food and nutrient standards for school meals in Ghana. Optimization resulted in school food baskets that met cost, nutrient and food-based/acceptability targets but with substantial deviations from baseline. Achieving nutritional adequacy within cost limits increased reliance on animal-source foods and led to higher environmental impacts, indicating trade-offs between nutrition, affordability, and environmental sustainability.

Conclusion:
The study underscores LP’s potential for enhancing school meals in Ghana but highlights the need for increased financial investment for reaching dietary goals. Addressing local realities and cultural preferences is essential for implementing effective, sustainable school meal strategies and improving child health.

Women’s Empowerment Metric for National Statistical Systems (WEMNS): Development and psychometric assessment of a face-to-face survey module

Data to monitor progress towards gender-related Sustainable Development Goals (SDGs) remain limited. A comprehensive, concise set of metrics is needed for routine national data collection to monitor progress toward these goals. Our team developed and tested the Women’s Empowerment Metric for National Statistical Systems (WEMNS) survey module for use by national statistical offices and survey organizations in low- and middle-income countries (LMICs) to measure women’s and men’s empowerment. This paper summarizes the process of developing the WEMNS module and presents detailed results of a psychometric assessment of face-to-face surveys in Bangladesh, Malawi, and Nepal. Exploratory factor analysis and confirmatory factor analysis (CFA) in the pooled sample confirmed that most of the 13 item sets had adequately identified factor structures aligned with specific empowerment constructs and gender-related SDGs. In multi-group CFA assessing measurement equivalence of item sets across gender and countries, configural invariance was observed for 9 of 13 item sets across genders and across country settings. At least partial scalar invariance was observed for one item set across genders and no item sets across country settings. Spearman pairwise correlations among WEMNS factor scores derived from final CFA models showed weak associations, suggesting item sets were weakly related and distinct. Overall, Spearman pairwise correlations of 13 WEMNS-derived factor scores with external measures for basic needs, resources, agency, and subjective well-being were weak, but five moderately high correlations were conceptually aligned. In sum, the WEMNS measures require refinement and further psychometric assessment to confirm their use to make valid comparisons of empowerment across country settings and gender.

Under the weight of provision: Gendered mental load among smallholder farmers in Kenya

Invisible mental strain affects women and men, especially in rural areas. The effects of this strain can influence collective and economic decisions, impacting resilience in low-resource agricultural communities. Using qualitative data collected from focus group discussions with smallholder farmers in Western Kenya, we explored gendered strains of women and men, their social and psychological consequences, and the gender empathy gap. We conducted focus group discussions with 56 farmers and found that expectations of the roles of women and men in the household were clear. The “invisible burden” was present in the pressure to be hardworking and to provide financial means for the family as a man; and to care for the family and farm as a woman. The strain led to stress, worry, and deterioration of mental health, contributing to despondency, isolation, household conflict, and even mental breakdowns. Household members coped with the psychological strain in different ways. Men tended to use avoidance mechanisms, isolate themselves, or turn to alcohol consumption. Women mentioned talking to others about the strain. Both women and men also reached out to other people, took some kind of action, made plans or relied on their faith in God. Both women and men showed empathy toward one another; that is, they recognized the strain and the effects on their spouse. However, women appeared to show more empathy than men. Thus, the breadwinner strain borne by men and the family load borne by women was an important factor in rural areas, affecting household relations and decisions, which can ultimately affect household resilience. Given the negative social and psychological consequences of this invisible burden, mental health literacy trainings, gender transformative approaches, community dialogues, and gender-responsive extension services can be employed to help households to better cope with strain.

Evaluation of solar-powered cold storage and evaporative cooling system as off-grid methods for postharvest vegetable storage: Evidence from a laboratory Experiment in Nigeria

This study examined the postharvest storage potentials of a solar-powered cool storage and an off-grid, metal-in-wall evaporative coolant. Temperature drop and relative humidity (RH) increase were used to analyze the performance of cooling systems. Tomato (United Trading Company (UTC) variety), orange (Dan Benue variety) and carrot (Orange Chantenay) were obtained from the international fruits market in Dutse, Jigawa State, Nigeria. The items were sorted and stored in three different storage conditions: room temperature (RT), solar-powered cold storage, and metal-in-wall evaporative cooling systems. Mass loss, color, hardness, total soluble solids and titratable acids, carotenoids, vitamin C, and rate of nutrient degradation were among the quality indicators tested. The study shows that the solar-powered cold storage outperformed all other storage methods across the evaluated parameters; it preserved fruit firmness, significantly reduced the rate of color change, and minimized mass and nutrient losses, outperforming the metal-in-wall evaporative cooling system. For instance, tomato mass losses observed in 24 days were 42.66, 63.79, and 85.45 percent in the solar-powered cold storage, evaporative coolant, and ambient storage, respectively. Economic advantages of the above technologies, however, require careful consideration of investment costs and longer-term durability and benefits.

Five misconceptions distorting food policy in Malawi: A joint NPC-IFPRI position paper

Among countries not affected by conflict, Malawi has the lowest GDP per capita, and its economy has been shrinking for much of the past five years. External shocks have undoubtedly strained an already fragile economy, but policy choices have further stifled growth and amplified vulnerabilities. Many of these choices are rooted in persistent misconceptions, that distort decision-making and undermine progress. This position paper identifies and challenges those misconceptions. We focus only on beliefs that are widespread, lead to seriously distorted policy choices, and are genuinely held by well-intentioned actors committed to inclusive development in Malawi. These actors are our primary audience, as those without this underlying objective are unlikely to be swayed. Our list is selective rather than exhaustive, concentrating on misconceptions that are particularly pervasive and influential in the food systems policy space, and for which robust, evidence-based arguments exist.

Linking Malawian smallholders to larger-scale agribusiness enterprises for inclusive development: A conceptual critique of the anchor enterprise model

While smallholder farming has been and remains at the center of agricultural transformation efforts in Malawi, the limited success of smallholder-centered agricultural development strategies has led policymakers to explore alternative approaches. One emerging approach involves larger farms or agribusiness firms partnering with smallholder farming households, in what we will refer to as an anchor enterprise model. Under this model, smallholder farming households contribute land and labor to produce crops or livestock products that serve as inputs for, or are marketed jointly with, the anchor enterprise. In return, the anchor enterprise provides support such as technical assistance, inputs, transport, or storage. This partnership is intended to be commercial and mutually beneficial. While support for such partnerships is growing and the anchor enterprise model is increasingly being used in development programming in Malawi, there is still little clarity on what they involve, what they aim to achieve, and the conditions they need for success. This study seeks to address these questions and assess whether such linkages between larger farms or agrifood processors and smallholder farming households can contribute to sustainable, resilient, and inclusive wealth creation in Malawi. The findings from this study are also summarized in a policy note (Benson, Cockx, and De Weerdt, 2025).

Anchor enterprise partnerships can be valuable development models in specific contexts. In particular, they can help both larger enterprises and smallholders overcome constraints imposed by weaknesses in Malawi’s factor, input, and output markets, enabling both land and labor to be used more productively. However, the viability of the model depends heavily on the nature of the product at its center. Anchor enterprise models are generally not suitable for grain or other generic staple crops. For such products, partnerships are costly and carry high risk since farmers can easily find and sell to other buyers than their anchor enterprise partner if market prices rise above the agreed price for the partnership (side-selling). Similarly, if market prices drop below the agreed price, enterprises may buy elsewhere (side-buying). Rather, these partnerships are most likely to be economically justified for higher value, less widely grown, more specialized, more complex to produce or process, or highly perishable agricultural products. For these products, the risk of default is lower as the reduction in transaction costs provides both parties with strong incentives for maintaining a longer-term commercial relationship.

These incentives are especially important as the legal framework governing commercial partnerships in Malawi’s agrifood sector remains underdeveloped. Formal contracts were found to be important but not central to successful anchor enterprise operations. Partnerships that endure are built on a strong economic rationale, clear financial incentives for all parties, and a degree of bilateral dependency.

Anchor enterprise models cannot be profitably and sustainably employed for many types of commercial agricultural production in Malawi. Consequently, only a small portion of farming households can directly participate, and the poorest and most vulnerable are generally less likely to be included. Nonetheless, where such models work well, they can deliver indirect benefits to the broader rural community, including its poorer and more vulnerable members, by stimulating local demand for labor, goods, and services. Complementary interventions aimed at strengthening the capacity of the poorest households to capture these indirect benefits may, however, be necessary for the model to contribute meaningfully to inclusive development.

A model centered around commercial farms or agro-processors requires an enabling environment for such enterprises to operate effectively. This includes macroeconomic stability, an investment climate that facilitates private investment in agribusiness, and trade and exchange rate policies that support formal exports. To be sustainable, anchor enterprise models must be grounded in a strong economic rationale for partnering. Government and development partners can, however, support such partnerships without eroding their commercial foundations by, for example, investing in new institutions for conflict prevention and resolution, providing enterprises with assistance in managing relationships with smallholder partners, organizing financial and business training for farmers to reduce information asymmetries, or supporting organizations that can act as effective third-party intermediaries.

Can cash and therapy work in conflict settings?

A randomised evaluation of a cash and psychological intervention in Ethiopia shows that the joint intervention is needed to improve both mental health and economic outcomes, but the effectiveness of the combined intervention is attenuated by active conflict.

Origins and causes of Sudan’s conflict: Domestic and international perspectives

The war between the Sudanese Armed Forces (SAF) and its subsidiary paramilitary Rapid Support Forces (RSF) that began in April 2023 follows a succession of civil wars that devasted the economically marginalized, socially ostracized, and politically disenfranchised southern and western regions of Sudan, but it has now brought the conflict to the country’s geographic and economic power center. Unlike the decades-long North–South civil wars or the ongoing deadly conflict in Darfur, today’s conflict began in Khartoum and the agriculturally rich heartland of Central Sudan, bringing death and destruction to the central Aj Jazirah and Sennar states, before moving south and west to Darfur and Kordofan. The same historical, economic, political, and ethnic factors that fueled those previous conflicts are at play now, as the belligerent factions seek to control the country’s resources. This time, however, after working together to halt efforts to democratize Sudan, the SAF and RSF turned on each other, each seeking to dominate the kleptocratic state system.

Introduction [in War and resilience: The multifaceted impacts of Sudan’s conflict and pathways to recovery]

Sudan is experiencing one of the most severe humanitarian and economic crises in its modern history due to the ongoing conflict between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF). The war has devastated livelihoods, displaced millions, and significantly weakened the country’s agrifood system and broader economic structure. Since the conflict erupted in April 2023, it has escalated into the world’s largest displacement crisis, with nearly 12 million people—nearly one-third of Sudan’s population-forced to flee their homes, including 4.5 million refugees who have sought safety in neighboring countries, including Egypt, Chad, South Sudan, and Ethiopia.

Conflict-induced trade dynamics: A gravity framework analysis of Sudan’s agricultural exports

Long before the April 2023 eruption of armed conflict between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF), Sudan’s economy was crippled by conflicts. The country’s agricultural production and productivity, internal trade, exports, and overall macroeconomic performance have all been adversely affected, and disruptions to the agrifood system, food insecurity, poverty, and malnutrition will likely remain if the conflict continues.

State failure and elite capture of Sudan’s agrifood system

Since the outbreak of Sudan’s civil war in April 2023, nearly 12 million people have been displaced, and an estimated 44,000 have been directly killed by the violence (UNHCR 2026; ACLED 2025). Many more are estimated to have suffered from war-related disease and malnutrition (Roberts 2025). The decimation of the capital city of Khartoum—the epicenter of the jubilant civilian uprisings in 2019—epitomizes the country’s short journey from a promising democratic opening to a failed state.

Worsening food security in Sudan amid conflict

The conflict in Sudan, primarily between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF), has escalated since April 2023 into a significant crisis, affecting the nation’s stability and security and worsening humanitarian conditions. The conflict has severely degraded the food security of many Sudanese households, with profound effects on their diets, coping strategies, and overall welfare.

Human capital at risk: The impact of conflict on health and education in Sudan

Human capital, including the knowledge, skills, and health of a population, is the foundation for economic growth and development (Lucas Jr. 1988; Mankiw et al. 1992; Pelinescu 2015). Healthcare and education stand out as critical pillars that directly enhance human capital, influencing individual well-being, workforce productivity, and development (Barro and Sala-i-Martin 1995; Schultz 2003; Hanushek and Woessman 2012). Access to quality healthcare ensures a healthy and productive population capable of contributing to economic activities, while education equips individuals with the skills and knowledge essential for innovation and global competitiveness. Together, these sectors constitute the backbone of a nation’s resilience and long-term prosperity (Kim and Ahn 2020; Wang and Gu 2024).

Cereal production, markets, and policy in Sudan

Cereal production has long been a cornerstone of Sudan’s food security and economy, especially wheat, sorghum, and millet. Given the importance of these staples, policy related to imports and prices of wheat (and sorghum, to a lesser extent) has major effects on food production and consumption. In particular, before 2023, government interventions in wheat markets involved huge implicit—and sometimes explicit—fiscal costs, including interventions on large food aid inflows, official sales prices, direct controls on commercial imports, and subsidies on wheat milling (D’Silva and Badawi 1988; Faki and Taha 2009; Abdelaziz et al. 2022). These policies have generally benefited urban consumers at the expense of rural producers and have not always been well-targeted to the poor (Resnick 2021; Resnick 2026, Chapter 3 in this volume).

Economywide impact of Sudan’s conflict and pathways to recovery

Massive human displacement and economic devastation have resulted from Sudan’s ongoing conflict, which erupted on April 15, 2023, between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF). According to the United Nations High Commissioner for Refugees, as of February 2, 2026, nearly 12 million people were internally displaced in Sudan, and 4.5 million had sought refuge in neighboring countries (UNHCR 2026). Public services, including health, education, and sanitation, have collapsed in many regions, compounding the humanitarian crisis and further destabilizing the socioeconomic fabric of the country.

Monitoring economic activities: Leveraging satellite and remote-sensing technologies

Understanding disruptions to economic activities in conflict-affected regions such as Sudan is essential for policymakers, humanitarian organizations, and researchers seeking to develop effective response strategies. However, traditional data collection methods, such as official government statistics and household surveys, become unreliable or impractical in these contexts due to security risks, displacement, and institutional breakdowns. In such environments, satellite and remote-sensing technologies provide a powerful alternative, offering near real-time, scalable, and objective insights into economic disturbances, infrastructure damage, population displacement, and environmental degradation. Advances in Earth observation technologies now allow researchers to monitor the economic consequences of conflicts with great accuracy and efficiency, even in regions where on-the-ground data collection is impossible (Hoogeveen et al. 2016; Hoogeveen and Pape 2020; Abay et al. 2023).

Food consumption patterns and dietary diversity amid conflict

Sudan is currently experiencing one of the most severe food security crises globally. According to the Integrated Food Security Phase Classification (IPC) more than 21.2 million people—45 percent of the population—are acutely food insecure (IPC Phase 3 or above), with more than 146,000 people facing catastrophic levels of food insecurity (IPC Phase 5) as of February 2026 (IPC 2025). As of September 2025, El-Fasher (North Darfur) and the besieged town of Kadugli (South Kordofan) were classified as experiencing famine (IPC Phase 5) with reasonable evidence. These conditions were expected to persist through January 2026. The crisis has also led to the acute malnutrition of 4.7 million children under five and pregnant and breastfeeding women and girls (IPC 2024a).

A Sudanese strategy for postconflict, agriculture-led transformative growth

The intense factional war between the Sudanese Armed Forces (SAF) and the paramilitary Rapid Support Force (RSF) that erupted in April 2023 has devastated Sudan. This war is a tragic legacy of the kleptocratic regime of General Omar Al-Bashir, which ruled the country from 1989 until it was deposed by the leadership of the two armies in 2019, following a massive popular uprising in December 2018 (see Chapter 2 for details). The presence of a divided military institution in Sudan has been attributed to the coup-proofing strategy of “coup-fearing” autocrats, who were willing to undermine the state’s military effectiveness to extend their own tenure (Powell 2014).

Delivering aid amid active conflict and insecurity: Digital transfers for delivering social and humanitarian assistance in Sudan

The recent resurgence of armed conflict in Africa is increasing the need for shock-responsive humanitarian and social assistance programs. For example, the armed conflict in Sudan, which erupted in April 2023, has caused the world’s largest displacement crisis, creating a multifaceted humanitarian crisis that requires significant investments in assistance. Armed conflicts in Africa are aggravating poverty and hunger (Corral et al. 2020) and threatening important gains in poverty reduction made in the last few decades. This is causing major setbacks to achieving the Sustainable Development Goals (SDGs) by 2030 (Corral et al. 2020; World Bank Group 2020), particularly SDG2 (Zero Hunger), SDG3 (Good Health and Well-Being), and SDG16 (Peace, Justice, and Strong Institutions).

Drivers of vulnerability and low resilience in Sudan

Sudan is currently facing one of the most severe crises in its modern history, with conflict, economic collapse, and climate disasters driving unprecedented levels of instability. Since April 2023, when the conflict erupted between the Sudan Armed Forces (SAF) and the Rapid Support Forces (RSF), the country has experienced a complete breakdown in governance and a near-total collapse of key economic and social structures, leading to one of the world’s largest internal displacement crises and an escalating humanitarian emergency.

Shocks, coping, and household livelihood strategies in wartime

Since the eruption of conflict between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF) in April 2023, Sudan has experienced one of the most severe humanitarian and economic crises in recent history. Beyond the tragic toll in lost and displaced lives, the conflict has profoundly disrupted livelihoods, dismantled social safety nets, and eroded the foundations of food and income security across the country. The ongoing war has affected millions, displacing communities and decimating livelihood systems across both rural and urban areas.

Toward a prosperous and secure Sudan: A way forward

As Sudan’s ongoing conflict enters its third year, the scale of human suffering and economic devastation continues to escalate. The brutal war between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF) has devastated livelihoods, shattered infrastructure, and crippled the country’s agrifood systems and broader economy. Nearly 12 million people—one-fourth of Sudan’s population—have been displaced, including more than 4 million refugees who have fled to neighboring countries such as Egypt, Chad, South Sudan, and Ethiopia (UNHCR 2026). The death toll is estimated to be more than 44,000 as of September 2025 (ACLED 2025), though some assessments suggest fatalities could exceed 150,000 when accounting for deaths from violence, starvation, and disease (Sampson 2025). Children have borne the brunt of this devastation: 16 million are in urgent need of humanitarian assistance, and more than 17 million school-age children are currently out of school. The widespread destruction of hospitals, schools, and essential services continues to deepen the crisis, threatening to reverse decades of development and push the country toward systemic collapse.

Spatial disparity, information, and the economics of cool transportation: Insights from a randomized controlled trial in Nigeria

Food loss is a significant source of economic inefficiency in value chains. In many developing countries, including Nigeria, a majority of fruits, vegetables, and other perishable foods are lost after harvest, due in large part to inadequate postharvest handling or low adoption of post-harvest management technologies, particularly cooling technologies such as temperature-controlled transportation and cold storage. To examine the economic impacts of cool transportation connecting vegetable-producing states in northeast Nigeria to large demand centers in Nigeria’s southern regions, we introduced a randomized controlled trial. Cool transportation was found to have a large and statistically significant impact: sales price, revenues, and profits increased substantially for the origin-state marketers. A larger portion of sales price increase at the destination market is attributed to refrigeration, that is, quality preservation through cooling. About 66 percent of this increase comes from cooling, with an additional 34 percent from transportation. An information experiment further showed that improved quality information through labelling that identifies the origin of the produce creates price premiums at the destination market. This implies that significant economic gains can be generated not only from narrowing supply–demand gaps in different markets but also, potentially, through mitigating spatial asymmetric information.

War and resilience: The multifaceted impacts of Sudan’s conflict and pathways to recovery

Sudan is facing one of the most severe humanitarian and economic crises in its modern history. The current civil war has displaced millions and severely damaged livelihoods, markets, and institutions, causing a rapid deterioration in the economy, agrifood systems, and population welfare.

War and Resilience: The Multifaceted Impacts of Sudan’s Conflict and Pathways to Recovery situates the current conflict within Sudan’s longer historical trajectory, explaining how structural factors contributed to the war’s progression and scale. Drawing on recent household and enterprise surveys, satellite indicators, market price data, and economywide modeling, the book documents the crisis’s impacts and identifies realistic entry points for stabilization and recovery.

Written by leading IFPRI researchers and colleagues, War and Resilience highlights how Sudan’s population has shown remarkable resilience through social networks, remittances, informal support systems, and adaptation across rural and urban settings. Its final chapters offer decision-makers a forward-looking assessment of pathways toward recovery.

IFPRI Malawi maize market report, March 2026

Average retail prices of maize declined by 6 percent in March. Imports of newly harvested maize from Mozambique depressed retail prices in Southern and Central Malawi, while exports to Zambia and Tanzania propped up prices in Northern Malawi, reducing regional price differences in the country.

Pre- and postharvest losses and their correlates in the millet value chain in Nigeria

Food losses continue to constrain food security, rural incomes, and agrifood system efficiency in sub-Saharan Africa, yet comprehensive micro-level evidence across entire value chains remains scarce. This study provides a detailed assessment of pre- and postharvest losses along the millet value chain in northwestern Nigeria, focusing on producers, aggregators, and processors in Sokoto and Zamfara states—two major millet-producing regions. Millet is a nutritionally rich and climate-resilient staple that plays a critical role in Nigeria, making loss reduction in this value chain particularly important for food system resilience.

The analysis draws on a purposefully designed baseline survey conducted in 2024, covering 595 millet producers and downstream value chain actors. The study applies a novel attribute-based loss measurement methodology that captures both quantitative losses (physical grain loss) and qualitative losses (quality degradation and associated price penalties), allowing estimation of losses in both volume and value terms across multiple nodes of the value chain. In addition to descriptive loss accounting, econometric models are employed to identify factors correlated with the incidence/likelihood and intensity of preharvest and postharvest losses at the producer level.

The results show that millet losses are widespread and concentrated at early stages of the value chain. Nearly all producers experience losses, with preharvest and on-farm postharvest stages accounting for the largest share. Total losses along the value chain average about 9 percent of total volume of production and 6 percent of total value of production. These estimates are comparable to the findings by the African Postharvest Losses Information System of approximately 9 percent millet losses in postharvest production activities in Nigeria. Producer-level losses dominate overall losses, although processors also incur substantial losses during storage, handling, and transportation. Spillage, pest infestation, moisture exposure, and inadequate handling practices are the most frequently reported causes of postharvest losses among downstream actors, although losses by aggregators are generally low.

Loss patterns vary systematically across space and demographic groups. Producers in Zamfara experience significantly higher losses than those in Sokoto, with preharvest losses playing a more prominent role. Youth and male producers incur higher total losses than mature producers, while gender differences are also observed in the composition and timing of losses across production stages. These patterns underscore the importance of spatially targeted and demographically sensitive loss-reduction strategies.

Econometric results highlight the central role of technology adoption, asset ownership, and management practices in loss reduction. Higher education levels, greater asset ownership, and larger farm size are associated with lower loss intensity, while preharvest shocks significantly exacerbate postharvest losses. The use of improved transportation, winnowing, and storage technologies substantially reduces postharvest loss intensity, whereas higher rainfall and temperature during postharvest periods increase losses.

Overall, the study demonstrates that food losses in Nigeria’s millet value chain are systemic but largely preventable. Effective loss reduction requires integrated, value chain–oriented interventions that combine improved production and postharvest technologies, climate adaptation measures, infrastructure investment, and targeted support for youth and smallholders. By providing rigorous micro-level evidence across multiple value chain nodes, the study strengthens the empirical foundation for food loss reduction policies and agrifood system transformation in Nigeria.

Fruit intake among women of reproductive age in northern Tanzania: Baseline findings from the FRESH end-to-end evaluation

To ensure overall health and reduce risk of non-communicable disease (NCDs), a healthy diet low in fat, sugars and salt and high in fruit and vegetables (F&V) is recommended. In most population groups, however, F&V intake is below the World Health Organization (WHO) recommendation of 400 g per person/day. In Tanzania, a recent scoping review found that F&V intake was below recommended levels in all population groups examined. Low F&V intake is due to a complex interplay of desirability, affordability, accessibility and availability.

The CGIAR Research Initiative on Fruit and Vegetables for Sustainable Healthy Diets (FRESH), now under the CGIAR Science Program on Better Diets and Nutrition (BDN), is designing an end-to-end approach to be evaluated in Northern Tanzania, as previously described in the Research Brief 1. A baseline survey was implemented, and dietary intake and nutrient adequacies among women of reproductive age (WRA, 15-49 years of age) participating in the baseline survey were summarized elsewhere. Here we provide a deep dive into fruit intake among these women.

Systematic risk profiling: Assessing compounding economic risks in developing countries

This paper presents a systematic risk profiling (SRP) framework to identify the most critical economic risks facing developing countries. Integrating computable general equilibrium (CGE) models with historical shock data and machine-learning tools, we examine how compound shocks affect development outcomes. We apply this method to Kenya, Rwanda, and Malawi, simulating thousands of plausible combinations of world price, capital flow, and productivity exogenous shocks and their impacts on countries’ GDP, household consumption, poverty, and undernourishment. The results reveal distinct risk profiles driven by structural differences: Kenya’s primary vulnerability is the volatility in global beverage crop prices, whereas Rwanda and Malawi face the highest risks from domestic root crop and cereal yields, respectively. These findings underscore that vulnerability is not just a function of shock magnitude, but of the specific structure of each economy. Specifically, the high economic volatility in Malawi and Rwanda is driven by the larger role of subsistence agriculture and more volatile domestic yields, whereas Kenya’s agricultural sector is more export-oriented. Unlike standard ad hoc scenario analysis, SRP quantifies both the likelihood of compound events and the relative importance of their drivers. This transparent, scalable framework provides policymakers a new tool to move beyond reactive measures and design targeted, country-specific resilience strategies for an increasingly volatile world.

The effects of cash and group therapy in the context of conflict: Evidence from a randomized evaluation in Ethiopia

The prevalence of depression remains high in low-income contexts, particularly those affected by conflict. This paper reports on a randomized controlled trial conducted in rural Ethiopia assessing the effects of a psychological (group therapy) intervention delivered by non-specialist health staff, as well as a large one-time cash transfer delivered post-therapy. The trial includes three arms comparing group therapy, cash, and both jointly to a status quo control within a sample of individuals reporting some depressive symptoms or functional impairment at baseline. The study occurred between 2022 and 2024, during a period of active armed conflict. Findings show that sixteen months post-baseline, there are no persistent positive effects of group therapy alone; cash alone improves time use and economic outcomes. Group therapy and cash jointly improve psychosocial skills, time use, and economic outcomes, and in areas not affected by conflict, the joint intervention also improves mental health.

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.

Haemoglobin concentration thresholds that discriminate functional outcomes among children aged 6–30 months in eight countries: A pooled analysis of individual participant data

Introduction The WHO cut-offs to define anaemia among children (haemoglobin, Hb <105 g/L in 6–23 months and <110 g/L in 24–59 months) are based on the distribution of Hb concentrations in a healthy population. Our objective was to identify Hb values that best discriminate functional outcomes among children aged 6–30 months. Methods We used previously compiled datasets from an individual participant data meta-analysis of effects of small quantity lipid-based nutrient supplements. Participants were eligible for this pooled analysis if they had Hb measured at 6–30 months and data on at least one functional outcome of interest, which included physical activity and sleep patterns, and language, socioemotional and motor development. We stratified the datasets by child age in 3-month intervals and analysed associations of Hb with both concurrent and subsequently measured (longitudinal) outcomes. If Hb significantly discriminated the 25th, 50th or 75th percentile of the outcome based on the pooled area under the receiver operating characteristic curve (AUC), we identified the Hb value with the highest concordance probability as the best discriminatory threshold. Results 11 datasets from 8 countries including 27 626 children were analysed. Hb significantly discriminated 21 of 47 concurrent and 11 of 32 longitudinal Hb-outcome associations. Best Hb discriminatory thresholds ranged from 102 to 111 g/L for concurrent physical activity outcomes, 103–116 g/L for concurrent developmental outcomes, and 109–117 g/L for longitudinal developmental outcomes. The I2 for the pooled AUC analysis indicated generally low to moderate heterogeneity across studies. Conclusions The current WHO cut-offs to define anaemia among children are in the middle to upper range of Hb values that best discriminate concurrent physical activity and development, and are in the lower range of values that best discriminate subsequent child development. Along with other types of evidence, this study provides additional evidence to inform Hb cut-offs to define anaemia among young children.

Nutrition, diet, and academic performance among school-age children in urban low-income settings: A case-control study in Addis Ababa, Ethiopia

Objective
To examine the effects of nutrition, dietary practices, and other related factors on academic performance and IQ among children in Addis Ababa, Ethiopia.

Methods
A case-control study was conducted among 309 children aged 6–14 years attending public and private schools in low-income districts of Addis Ababa from March to August 2023. Binary and multinomial logistic regression models were used to estimate crude (COR) and adjusted odds ratios (AOR) with 95% confidence intervals.

Results
Hand washing (AOR = 3.7; 95% CI: 1.4, 9.8), access to toilets (AOR = 3.37; 95% CI: 1.25, 9.09), and effective teaching (AOR = 2.94; 95% CI: 1.04, 8.33) good academic performance. Stunting (AOR = 0.16; 95% CI: 0.04, 0.59), underweight (AOR = 0.25; 95% CI: 0.09, 0.70), and overweight (AOR = 0.04; 95% CI: 0.01, 0.14) were associated with poor academic performance. Low meal frequency (AOR = 2.65; 95% CI: 1.06, 6.67) and teachers with BA/BSc degrees (AOR = 6.97; 95% CI: 1.14, 42.68) predicted lower IQ.

Conclusion
Many factors, especially nutrition and diet, strongly influence academic and cognitive performance; targeted school interventions improve outcomes.

Can simpler, cheaper graduation programmes still deliver?

A randomised evaluation of a lower-cost graduation-style programme in rural Ethiopia finds modest gains in savings and livestock income but no sustained improvements in consumption or food security, suggesting that smaller transfers and lighter support may be insufficient to help extremely poor households escape poverty, particularly in shock-prone settings.

Cooling technologies and long-term efficiency improvement of horticulture market agents: Panel data evidence from a solar-powered cold storage intervention in Nigeria

Modern cooling technologies that use renewable energy sources have been increasingly recognized as a promising tool to address a multitude of challenges emerging in progressively complex food systems in developing countries. When provided as cold storage inside horticulture markets, cooling technologies can contribute to improved quality of products and strengthened vertical linkages. Knowledge gaps about the medium- to long-term impacts of these technologies in developing countries remain, especially in Africa south of the Sahara (SSA). This study partly fills this knowledge gap by revisiting the 2021 short-term impact evaluation study (Takeshima et al. 2023) to assess the medium- to longer term impacts of interventions in northeast Nigeria in which 7 small solar-powered cold storages were installed across 7 horticulture markets. Combinations of difference-in-difference and variants of propensity score-based methods suggest that using cold storage significantly increased horticulture sales volumes and revenues of market agents. Using cold storage also reduced the share of food loss and lengthened the products’ shelf-life while raising prices received by both market agents and farmers, which were associated with improved product quality, expanded value-adding activities by market agents, and increased use of advance payments. We find no evidence of negative spillover effects inside horticulture markets. Observed effects are driven by the technical improvements that raise the efficiency of the use of purchased raw commodities, enabled by cold storage, based on modified efficiency analyses. At the same time, the efficiency of cold storage use remains low despite some improvement over time, and scopes exist to enhance this efficiency.

Conceptualizing and measuring dimensions of tenure security: Gendered analysis from Malawi, Bangladesh, and Nepal

Women’s property rights and tenure security are recognized as critical for development policy and practice. Yet there is no consensus on how to conceptualize or measure these concepts. In this paper, we explore the relationships between perceived tenure security, as reported by survey respondents, with documentation and the bundle of rights that are often used to define property ownership. We use data from the pilot of the Women’s Empowerment Metrics for National Statistics (WEMNS) in Malawi, Nepal, and Bangladesh on both agricultural land and housing. The land rights module was designed to match indicators being collected to support the Sustainable Development Goals (SDGs). Similar questions were asked regarding the dwelling. Regression results find few associations between perceived tenure security and property rights (holding individual or sole land rights, having your name on a document, and holding rights to sell and bequeath). We thus use Sankey diagrams to visualize these relationships. In Malawi, two-thirds of those without documents, both men and women, are tenure secure. In Bangladesh, over half of the respondents are landless and thus do not have tenure security. Two-thirds of Bangladeshi women respondents in landed households report that they are tenure secure, in spite of not having their own names on the documents. In Nepal, we find a high level of both property ownership (90 percent) and tenure security (80 percent). The patterns differ across contexts and between land and housing. The results confirm that the documentation of rights and having sole or joint rights are important but should not be conflated with tenure security.

IFPRI Malawi maize market report, February 2026

Average retail prices of maize recovered from a January slump before returning to a longer-term trend of marginal decline.

Retail price changes were driven by changes in the cost of imported maize.

Imports dominated cross-border trade in maize despite some strong but localized informal exports to Zambia and Tanzania.

Hunger crisis is set to get worse in west and central Africa – why and what to do about it

Countries in west and central Africa are facing a food crisis with multiple causes. Estimates in late December 2025 suggested that 41.8 million people were already in crisis or worse in October-December 2025. The number was expected to rise to 52.8 million in June-August 2026. Researchers Kirui Oliver Kiptoo and Chibuzo Nwagbosu explain how serious the situation is.

The making of a non-parametric multi-shock index (MSI)

Households in low- and middle-income countries increasingly face overlapping economic, climatic, health, and conflict-related shocks that jointly erode welfare and food security. Yet many empirical and operational tools still measure shocks one at a time or aggregate them using ad hoc rules that assume equal severity and linear effects. This paper proposes a non-parametric multi-shock index (MSI) that summarizes household exposure to multiple shocks using an assumption-light, data-driven approach. The MSI construction proceeds in two steps: (i) shocks are empirically filtered based on their observed negative association with food security outcomes (anchored to the Food Consumption Score), and (ii) retained shocks are aggregated using alternative weighting schemes, including unweighted, population-weighted, and prevalence-weighted variants. We validate the MSI using multiple food security measures—Food Consumption Score (FCS), Reduced Coping Strategy Index (rCSI), Food Insecurity Experience Scale (FIES), and Household Dietary Diversity Score (HDDS). An application using FAO’s Data in Emergencies (DIEM) household survey for Nigeria illustrates the approach and shows that cumulative exposure—especially systemic and compound exposure—is strongly associated with deteriorating food security outcomes. Among tested variants, the prevalence-weighted MSI provides the clearest discriminatory power and distributional sensitivity, supporting its use for targeting, monitoring, and shock-responsive programming (FAO, 2016; Maxwell et al., 2014; World Bank, 2018).

A systematic scoping review of urban food environment research, interventions and measurement approaches in eight low- and middle-income countries

Background
Food environments in low- and middle-income countries (LMICs) are undergoing rapid transformation, particularly in urban and peri-urban settings. These shifts—characterized by changes in food retail landscapes, consumer purchasing behaviors, and the availability and affordability of nutritious foods—have significant implications for nutrition. Yet, the key characteristics of these environments, such as food desirability, convenience, accessibility, and marketing influences, remain underexplored. This systematic scoping review synthesizes evidence published between 2001 and 2023 across eight LMICs (Bangladesh, Sri Lanka, Philippines, Kenya, Ghana, Ethiopia, Rwanda, Peru) to examine how urban and peri-urban food environments shape dietary behaviors and nutrition outcomes.

Methods
Guided by a conceptual framework encompassing nine key food environment dimensions—availability, prices, marketing and regulation, vendor and product properties, accessibility, affordability, desirability, convenience, and sustainability—we analyzed descriptive, associative, and intervention studies. We searched Scopus and Web of Science, identified 1,609 records, and included 251 studies in the review.

Results
As might be expected in a growing body of evidence, most research is descriptive, with limited causal or intervention-based evidence. Studies frequently focus on characteristics of informal vendors, sociocultural factors influencing shifts in dietary choice toward unhealthier options, and the proliferation of ultra-processed foods, especially near schools and in informal markets. Associations between food environment and nutrition outcomes, such as elevated BMI and overweight, are often linked to supermarket and fast-food access, though these relationships are frequently confounded by socioeconomic variables. Methodological inconsistencies in defining and measuring food environment dimensions limit cross-context comparability. Only seven intervention studies were identified, with few demonstrating significant improvements in diet or nutrition.

Conclusions
This review highlights critical evidence gaps in urban food environments in LMICs and underscores the need for standardized measurement and robust evaluations of diet-related interventions. Strengthening this evidence base is essential to inform food policy, urban planning, and public health strategies that promote healthier diets for populations in rapidly urbanizing settings.

Impact of climate change on cost and cost efficiency of solar irrigation in Sub‐Saharan Africa

Irrigation is widely recognized as a promising strategy for enhancing agricultural productivity in Sub-Saharan Africa. To support its expansion, solar-powered irrigation systems are increasingly promoted as a sustainable alternative. However, unlike fossil fuel-based systems, the performance of solar irrigation is more sensitive to climate variability and change. This study assesses the impact of climate change on the cost and cost efficiency of stand-alone solar irrigation systems across Sub-Saharan Africa, using 15 CMIP6 climate scenarios. Our findings indicate that climate change is likely to increase investment costs and reduce the cost efficiency of solar irrigation systems compared to diesel-powered alternatives in most countries and agricultural areas of the region. Nevertheless, the expected decline in cost performance of solar irrigation systems is moderate and is likely to be offset by continued reductions in solar panel prices.

Estimating the number of people eating biofortified foods on-farm and from markets: A detailed methodology and tool

Background
Biofortification is a cost-effective and scalable approach to reduce micronutrient deficiencies. Currently there is scant data detailing the number (reach) and proportion (coverage) of individuals consuming biofortified foods, which is a key limitation for policymakers.

Objective
Develop a method to estimate the reach and coverage of biofortified foods using primary and secondary data sources.

Methods
We used data from 2023 to estimate the reach and coverage of zinc biofortified rice in Bangladesh and wheat in Pakistan, and vitamin A maize and cassava in Nigeria. Our calculation is divided into 5 phases: 1) seed availability, 2) agricultural production, 3) on-farm consumption, 4) off-farm consumption, and 5) overall national level reach and coverage. Phase 4 includes two consumption scenarios: full replacement and half replacement, where biofortified foods respectively account for 100% or 50% of the per capita consumption.

Results
In 2023, approximately 13 to 16 million people (8-9% of the population) consumed biofortified rice in Bangladesh. In Pakistan, between 97 to 173 million people consumed biofortified wheat (39-70% of the population). In Nigeria, biofortified maize was consumed by 42 to 66 million people (18-29% of the population) and biofortified cassava by 25 to 38 million people (11-17% of the population).

Conclusions
Our method estimates on-farm and off-farm reach and the reach/coverage of biofortified foods with visible and invisible traits. Because there is insufficient primary or secondary data describing the intake of biofortified foods, we estimated a range for off-farm reach. We estimate that in 2023, between 177 and 293 million people consumed the four biofortified crops explored in this analysis. This approach can be used to estimate the reach and coverage of other biofortified crops in other countries. More information about the consumption of these foods is needed to improve the accuracy of national reach and coverage estimates.

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

When the going gets tough: Experimental evidence of respondent fatigue in household surveys

Constructing per capita estimates (e.g., consumption), poverty rates, and other development indicators requires the listing of household members as well as their detailed demographic characteristics in household surveys using rosters. We designed an experiment to understand how respondents and enumerators manage such lengthy listing exercises in household surveys. We randomly assign respondents to ‘committed’ and ‘uncommitted’ household member listing rosters. If respondents are likely to reduce effort, they would decrease the number of household members reported in the uncommitted option, when they have the choice to list fewer members and save time. We find a 6–7% reduction in the number of household members listed when household rosters are enumerated with an uncommitted method, implying that 1 out of every 5 respondents reported an additional household member when asked using the committed household roster. Respondent/survey fatigue could explain the difference in the two measures of household size. Overall, our findings speak to the critical role of survey design in ensuring data quality and the important trade-off between survey length and data quality.

The Cash Transfer & Intimate Partner Violence Research Collaborative: Expertise, impact, and future directions

Violence against women and girls (VAWG) has severe long-term consequences for women’s health and well-being, imposes significant economic costs through lost productivity, and has intergenerational impacts on children. Although evidence exists on effective approaches to reduce VAWG, many interventions are resource-intensive and difficult to scale. Stakeholders increasingly recognize that accelerated progress requires embedding VAWG prevention and response approaches within diverse sectors, including in existing systems and large-scale sectoral programming. Sectors focused on reducing poverty and economic insecurity offer a particularly high-potential but underleveraged opportunity. Despite their extensive reach and influence over the structural drivers of VAWG, these sectors have not traditionally focused on VAWG reduction. The field lacks actionable evidence on how to leverage these large-scale systems to reduce VAWG in ways that governments and other key actors can adopt, finance, and sustain, including approaches that reach women and girls in fragile and climate-vulnerable settings.

Does Malawi’s exchange rate regime keep prices low? Evidence and policy implications

The current exchange rate regime in Malawi is untenable. It results in multiple effective parallel rates, which impose significant costs on the economy and the daily lives of citizens. A key concern underpinning the existence of the regime is that its removal would trigger rampant inflation and worsen livelihoods. However, the widespread importation of both food and nonfood products at informal exchange rates means that the average citizen derives little real benefit from the maintenance of the official rate. After two major fuel price hikes in recent months, pump prices have nearly converged with the cost that would prevail at market-determined exchange rates.

Drawing on a combination of price multiplier and food demand simulations, this policy note shows that an exchange rate regime rationalization – through devaluing the official exchange rate to eliminate the informal premium and allowing the Malawi kwacha to trade at market-clearing levels – would not lead to runaway inflation or harm household welfare. Recent fuel price increases – in October 2025 and January this year – have pre-emptively absorbed much of the inflationary impact that would have been associated with exchange rate reform.

Our analysis documents the direct, short-run effects of exchange rate unification on domestic prices and finds them to be relatively modest. Longer-term economic growth and sustained price stability will hinge on the effective execution of a coherent set of complementary reforms. Exchange rate unification is a necessary component of this package, but it is not sufficient. Implemented in isolation or treated as a one-off devaluation followed by business as usual, it will bring little relief. It must be accompanied by sound fiscal and monetary policy and sustained export growth to restore macroeconomic stability. We do not discuss the trade-offs inherent to these accompanying measures, as they have been addressed at length in AfDB et al. (2025) and Engel et al. (2025).

Critically, there must be a credible and durable switch toward a more flexible and transparent exchange rate regime. It will take time for exports and growth to pick up after a devaluation, and whether they do will depend on economic actors believing that macroeconomic conditions will remain stable over the lifetime of their investments. It will require careful preparation to get the cocktail right. Politically, the current administration might just have one shot at this: failure will make future reform attempts much harder.

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.

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.

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.

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.

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

This dataset contains output data of IFPRI’s solar irrigation sizing and cost estimation model which show the impact of climate change on investment cost of adopting stand-alone solar irrigation system and its cost efficiency relative to diesel irrigation system over Sub-Saharan African region.

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.
