Climate change affects every aspect of the food system, including all nodes along agrifood value chains from production to consumption, the food environments in which people live, and outcomes, such as diets and livelihoods. Women and men often have specific roles and responsibilities within food systems, yet structural inequalities (formal and informal) limit women’s access to resources, services and agency. These inequalities affect the ways in which women and men experience and are affected by climate change.

International food prices have become increasingly volatile in recent decades, with “global food crises” in 2008, 2011 and most recently in 2022. The 2008 crisis prompted international agencies to ambitiously extend their monitoring of domestic food prices in developing countries to strengthen early warning systems and food and nutrition surveillance. However, food inflation by itself is not sufficient for measuring disposable income or food affordability; for that, one must measure either changes in income or changes in an income proxy.

One of the Sustainable Development Goals (SDGs) is reducing food loss and waste (FLW) across all stages of food value chains, including the on-farm production, the off-farm postharvest, processing, and distribution, and the household consumption stages. We employ general equilibrium models for Bangladesh, Kenya, and Nigeria to assess the economywide implications of reducing FLW at different stages of value chains. Halving FLW results in GDP increases of between 1.1 and 2 percent, with up to 13 million people lifted out of poverty across the three countries.

Malawi has suffered from weak economic growth since its independence in 1964. Over 50 percentof the population live below the poverty line, unable to produce enough or to otherwise obtain suffi cient income to meet all of their basic needs. Poverty is concentrated in rural areas. Smallholder agriculture dominates employment in rural Malawi. However, with continuing population growth, the average landholding size for smallholder farming households is declining, resulting in many being unable to produce sufficient food to meet their own needs.

This analysis is composed of two parts. The evolving structure of Kenya’s agrifood system (AFS) and its contribution to national development is assessed using a series of Social Accounting Matrixes (SAMs) for Kenya for the period 2009–2019. Economic performance is also assessed at subsector level to better understand the contributions of different agrifood value chains to Kenya’s development and economic transformation in recent years.

During the last decade, post-harvest losses (PHL) reduction has been topping the agenda of governments as a pathway for addressing food security, poverty, and nutrition challenges in Africa. Using survey data from 579 households, we investigated the factors that affect farmers’ decisions to adopt post-harvest technologies: mechanized shelling, drying tarpaulins, and airtight storage validated for reducing PHL in Tanzania’s maize-based systems, and the impacts on households’ food security and welfare.

Crop yields in sub-Saharan Africa need to increase to keep pace with food demands from the burgeoning population. Smallholder farmers play an important role in national food self-sufficiency, yet many live in poverty. Investing in inputs to increase yields is therefore often not viable for them. To investigate how to unlock this paradox, whole-farm experiments can reveal which incentives could increase farm production while also increasing household income.

The intensification of agricultural systems in sub-Saharan Africa (SSA) is necessary to reduce poverty and improve food security, but increased nutrient applications in smallholder systems could have negative consequences for water quality, greenhouse gas emissions, and air quality.

Sub-Saharan Africa is grappling with surging food demand amid a growing population and challenges of climate change. Climate Smart Agriculture (CSA) emerges as a holistic solution, aiming to counter these complexities and enhance livelihoods. However, the evidence remains thin and mixed. We used a meta-analysis with 18 studies to assess the impacts of climate smart agricultural practices on livelihood indicators in sub-Saharan Africa. We find that adoption of climate smart agriculture is positively correlated with crop and household income and food security in sub-Saharan Africa.

Gendered inequities in access to and use of energy sources and technologies affect all five impact areas that CGIAR is contributing to: poverty alleviation, food security and nutrition, climate action, environmental health, and inclusion. This policy note identifies indicators that reflect women’s and men’s agency in the context of energy use and develops a first version of the Women’s Empowerment in Energy Index (WEEI) to measure changes in women’s agency over time.

The International Food Policy Research Institute (IFPRI) is organizing a hybrid launch event for its 2023 Global Food Policy Report in Nairobi, Kenya, in collaboration with University of Nairobi and as part of the CGIAR Initiative on National Policies and Strategies (NPS) seminar series on May 19, 2023, at 2.00pm.
The 2023 Global Food Policy Report, IFPRI’s flagship report, provides a broad set of evidence-based recommendations for better predicting and preparing for crises, addressing crises when they occur and building equity and resilience of food systems.
