TOPIC

Food Systems

Food systems are the sum of actors and interactions along the food value chain—from input supply and production of crops, livestock, fish, and other agricultural commodities to transportation, processing, retailing, wholesaling, and preparation of foods to consumption and disposal. Food systems also include the enabling policy environments and cultural norms around food. Ideal food systems would be nutrition-, health-, and safety-driven, productive and efficient (and thus able to deliver affordable food), environmentally sustainable and climate-smart, and inclusive. To realize this vision, continued investments must be made in agricultural research and development and technological innovations, paving the way for programs and policies that are based on sound evidence.

IFPRI conducts research and offers policy support on a range of food system issues from farm-level productivity to development of inclusive food value chains to nutrition education—providing evidence for design of food systems that provide people with equitable access to nutritious, sustainable diets and contribute to more broadly to development and well-being.

IFPRI’s research on this topic is closely aligned with the Sustainable Development Goals (SDGs), including SDG 1, SDG 2, SDG 12, SDG 14, and SDG 15.

Myanmar Monthly Food Price Report – November 2024

The rapidly evolving food security situation in Myanmar requires a high frequency, systematic and comprehensive approach to monitoring. The Myanmar monthly food price report synthesizes food price trends using publicly available datasets, focusing on key agricultural crops and highlighting regional differences in rice prices. By analyzing these trends, the report aims to provide insights into the broader agricultural market and the factors driving food price fluctuations in Myanmar.

Adapting the women’s empowerment in nutrition index: Lessons from Kenya

Adapting the women’s empowerment in nutrition index: Lessons from Kenya

Women face a disproportionate burden of malnutrition and food insecurity. Research has shown that women’s empowerment can buffer women against nutritional problems. This paper contributes to ongoing efforts to measure women’s empowerment that are both context-sensitive and universal, focusing on the recently developed Women’s Empowerment in Nutrition Index (WENI). Earlier research has shown it is both a valid construct and positively related to dietary and nutritional outcomes of women in South Asia. We establish that WENI is generalizable to agropastoral and pastoral Kenya, an area with substantially different livelihoods, food system, norms, and institutions than South Asia. We find that a locally contextualized WENI is strongly associated with women’s body mass index and dietary diversity as well as household level food insecurity. We also present findings for two shorter variations of WENI: an abbreviated WENI (A-WENI) and a cross context WENI (CC-WENI). A-WENI contains a small subset of WENI indicators identified using machine learning with South Asian data and therefore is context-specific. CC-WENI does not contain indicators specific to the validation context. We find that they perform comparably well with caveats. Thus, as use of WENI expands we recommend adapting WENI for in-depth analyses of women’s nutritional empowerment; using CC-WENI for cross-context comparisons; and using A-WENI for rapid appraisals of community level progress in a given context.

Comprehensive mapping of food systems is necessary to guide transformation efforts: The case of Rwanda

Comprehensive mapping of food systems is necessary to guide transformation efforts: The case of Rwanda

Rwanda has made significant strides in improving its food systems, with notable progress in reducing malnutrition and stunting, especially among children. Stunting rates declined from over 50% in the early 2000s to 33% by 2020, reflecting the government’s commitment to addressing food insecurity and enhancing nutrition through a range of agricultural and public health initiatives. The country’s Crop Intensification Program (CIP) has played a pivotal role in increasing agricultural productivity, especially for staple crops like maize, beans, and Irish potatoes, which has contributed to better food availability across the country. Despite these achievements, substantial challenges persist. Almost 19% of households still face food insecurity, with the highest prevalence in rural areas. Additionally, malnutrition continues to affect vulnerable populations, with anemia rates among women of reproductive age at 37%, signaling gaps in nutrition security. Environmental concerns, including soil degradation, water scarcity, and climate change, further complicate efforts to sustain agricultural productivity. Approximately 40% of Rwanda’s land is affected by soil erosion, and shifting climate patterns pose increasing risks to agricultural yields. These challenges indicate the need for a more strategic, research-based approach to understanding and transforming Rwanda’s food system.
