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.

Mobile livestock production in the Sahel and West Africa is a way of life and a form of adaptation and resilience developed over thousands of years by pastoralists and agro-pastoralists to cope with the effects of desertification and climate change, and to make the best use of the vast expanses of arid and semi-arid regions. This livestock farming system makes it possible to seek complementarities with the agro-ecological zones of the southern savannah regions through the use of pasture and water. In this way, livestock farming helps to provide substantial income for the local population and ensure food security. The N’Djamena symposium in the Republic of Chad (May 2013) and the Nouakchott declaration in the Islamic Republic of Mauritania (October 2013) gave renewed interest to the livestock sector with the implementation of several regional initiatives such as PRAPS, PREDIP, PEPISAO financed respectively by the World Bank, the European Union and the Agence Française de Développement and coordinated by CILSS as well as others such as PACBAO, MOPSS, etc.

i) The Economic Community of West African States (ECOWAS) is a pioneer in establishing regulations for the exercise of cross-border transhumance, a somewhat controversial livestock production system in relation to its economic, social and environmental impacts, and the conflicts of access to natural resources that are sometimes associated with it. ii) Since 1998, ECOWAS has been experimenting with a set of legal and technical instruments to provide a framework for the exercise of this multi-functional credited activity, which makes it a powerful means of strengthening the resilience of populations in general, and pastoralist and herder households in particular, on the one hand, and promoting social and regional integration in West Africa, on the other.

CILSS has achieved significant results and a great deal of experience through the PREDIP implementation. A sample of eleven (11) major experiments and lessons learnt have been drawn up and documented using the “ongoing capitalisation» approach, with a view to building on these achievements for the benefit of stakeholders in the livestock and pastoralism sub-sector in the Sahel and West Africa. The experiments cover all the themes addressed by PREDIP (i.e., regional pastoral information service, dialogue and governance on cross-border transhumance, agro-pastoral infrastructures and facilities, animal health). Each of the fact sheets documenting these experiments includes a short summary giving the reader an overview of the content of the experiment and enabling him or her to extract the information he or she needs. In addition to these eleven (11) sheets, two (2) capitalisation notes have been produced. These experiments and capitalisation notes can be scaled up for greater value. They complement the existing body of knowledge on the promotion of the livestock sub-sector.
