Overview

Ending hunger and enabling safe, affordable, healthy diets for the world’s most vulnerable people

Food security and nutrition are key to human well-being. Far too many people around the world are affected by malnutrition ranging from undernutrition to problems of overweight, obesity, and diet-related noncommunicable diseases. Achieving sustainable healthy diets…. 

IFPRI research addresses food insecurity from multiple angles, including providing foresight and real-time monitoring on market supply and trade of major crops; policies and investments to improve availability of food through better infrastructure, logistics, and markets; the role of social protection programs, including cash transfers, in improving food security and diets; and   Work on gender and equity explores how access to and decision-making around food production, sale, and consumption affect food security and nutrition, and the policies and educational programs that can improve access for women, children, and adolescent girls.

To understand the intrinsic links between food systems, nutrition, and health, IFPRI addresses a range of issues antimicrobial resistance, nutrition-associated noncommunicable diseases, food safety, intimate partner violence, malnutrition, maternal and child health, social protection, and nutrition programs linked with agriculture and education programs to social protection. Improving nutrition requires contributions not only from the health sector but also from sectors as diverse as agriculture, social protection, gender, and education, which together can address the underlying causes of malnutrition. IFPRI’s nutrition research aims to generate rigorous evidence on what works—and what does not—to prevent malnutrition in low- and middle-income countries. IFPRI’s nutrition research expertise covers nutrition and dietary assessment; infant and young child nutrition; adolescent nutrition; maternal nutrition; and school-based and other multisectoral nutrition programs. IFPRI’s work on biofortification, which …., has increased access to essential nutrients for 100 million people, through development and dissemination of biofortified crops, including….

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.
