The Maharo resilience food security activity (RFSA) aims to address and mitigate acute levels of food insecurity experienced by communities in the southeastern region of Madagascar by providing development and nutritional support. The RFSA package also includes a range of community-tailored livelihood support activities. The primary objective of the impact evaluation (IE) of Maharo is to measure the impact of this added livelihood support on reducing food insecurity and increasing wellbeing for households through a randomized control trial design. The IE spans from 2021 to 2024 and uses BHA’s standard approach for impact evaluations. It comprises five components: a baseline, process evaluation, midline, endline, and cost-effectiveness analysis.
