This experience was shared at a workshop held in Lomé (Togo), from 29 to 31 October 2019, and organised by PEPISAO (Projet Elevages et Pastoralisme intégrés et sécurisés en Afrique de l'Ouest). It was complemented by amendments from about forty pastoral and agricultural associations from West Africa and Chad. The experience is based on "Using information systems to prevent conflicts related to pastoral mobility"; it is supported by the Réseau Billital Maroobé (RBM). RBM is a network of pastoralist organisations based in 9 West African countries, namely: Benin, Burkina Faso, Mali, Mauritania, Niger, Nigeria, Senegal, Chad and Togo. The network is expected to extend to Côte d'Ivoire and Ghana. RBM’s objective is to contribute to the recognition of the right to mobility and the security of pastoral land in order to promote negotiation amongst stakeholders, facilitate the alignment of national and regional regulations and provide arguments for advocacy. The information mechanism set up is entitled: "Observatory of rangeland and the integrity of transhumance and trade corridors for livestock mobility in West and Central Sahelian Africa -OPTIMAOC". This information mechanism is funded under Component 2 of the Regional Dialogue and Investment Programme for Pastoralism and Transhumance in the Sahel and Coastal Countries of West Africa (PREDIP) and is based in Niamey, Niger. PREDIP is a project coordinated by CILSS. In this "OPTIMAOC" information mechanism, there is a system based on sending SMS (short message service) and IVR (interactive voice response) to livestock farmers. This system is led by RBM and started in 2018. Its objective is to rapidly disseminate information to pastoralists. It is being tested in the departure areas of transhumant herders, their home areas, and border areas in the Republic of Benin. Today, this experience is being extended to other coastal and Sahelian countries. Although it is still new, some lessons can be learnt from this experience.
