This document constitutes the main report of the study on the social, economic and environmental impacts, the main drivers of change and the long-term prospects of mobile livestock systems in West Africa. The study was carried out between June 2020 and January 2021 as part of the implementation of the Integrated and Secure Livestock and Pastoralism Project in West Africa (PEPISAO). This regional initiative is funded by the French Development Agency and implemented by the Economic Community of West African States.

The result of a partnership between the Permanent Interstate Committee for Drought Control in the Sahel (CILSS) and the Food Security Information Network (FSIN), this report on food security and nutrition in West Africa and the Sahel provides timely and reliable data needed to address growing food security and nutrition challenges in the region. The food and nutritional situation is worrying for the 2024 lean season. Even though the number of people in the highest phases has significantly decreased in several countries since the 2023 peak, the aggregate number and percentage of people in CH Phase 3 or above are projected to be the highest ever recorded in CH history due to the interaction between conflict and civil insecurity, economic shocks, weather extremes, underlying poverty, and other vulnerability factors.
