The "Integrated and Secure Livestock Production and Pastoralism in West Africa" (PEPISAO) project is implemented by the Economic Community of West African States (ECOWAS), as Project Manager, and CILSS, as Delegated Project Manager, with the financial support of the Agence française de Développement (French Development Agency) (AFD) and the technical assistance of the IRAM/ISSALA/ LARES consortium. With a duration of four years (2018-2022) and an amount of five (5) million Euros, the project covers the ECOWAS zone plus Chad and Mauritania. It has been extended at no additional cost to 31 December 2023. The project has been implemented since 2019 in a regional context marked by: (i) the deterioration of the pastoral, food and nutritional situation, (ii) the resurgence of insecurity of goods and people; (iii) the prevalence of the COVID 19 pandemic, on the one hand, and by (v) a significant increase in the number of regional projects dealing with pastoralism and (vi) a relative deterioration in the governance of cross-border transhumance, on the other hand. However, the stakeholders were able to overcome the effects of these factors through their commitment, and the project has achieved a lot. This report capitalises on the major achievements and results of four years of implementation.
