To reduce poverty, food insecurity, and malnutrition, it is vital to choose the programs and policies that provide the largest impacts on development outcomes for a given level of expenditure. Since objective, systematic evaluations provide the evidence needed to compare the impact and cost-effectiveness of development interventions, IFPRI designs and implements evaluations using state-of-the-art empirical methods that rigorously measure the causal impact of interventions. Many evaluations also include a qualitative component to inform the mechanisms underlying program impact and may include operations research to identify ways to improve program delivery. IFPRI researchers work closely with government, donor, NGO, United Nations, and academic partners to design the evaluations in order to understand the contextual and behavioral determinants of poverty, food insecurity, and malnutrition and to answer the most pressing policy questions. Gender considerations are central to all evaluations and, where relevant their impact on women’s status and empowerment is assessed. Program evaluations are designed as learning exercises to understand the contextual and behavioral determinants of poverty, food insecurity, and malnutrition—but they can also improve transparency, making government and implementing partners more accountable.
