Brief presentation of CILSS/AGRHYMETCILSS: The Interstate Committee for Drought Control in the Sahel
• Created in 1973 by the Heads of States of 9 Sahelian countries
• Mandate: • Food security (drought risk management, poverty reduction)• Natural resources management , desertification control ,
water resources management, climate change adaptation
• Main statutory institutional instances• Summit of the Heads of States /Governments every 2 year• Council of ministers, twice a year• Regional Programming and Monitoring Board, twice a year
4
Brief presentation of CILSS/AGRHYMETCILSS: 9 member countries Cape Verde, Mauritania, Senegal,The Gambia, Guinea Bissau, Mali,Burkina Faso, Niger and Chad.
• Headquarters in Ouagadougou, Burkina FasoPolicy development and support
• 2 specialized institutions• INSAH : in Bamako, Mali
Coordinate agricultural research
• AGRHYMET: in Niamey, Niger Information and Training
• Since December 2006, MoU with ECOWAS to extend activities to all West African Countries (food crisis and other natural disaster prevention and management, natural resources management, desertification control and population and development research

Monitoring and Early Warning• Early Warning and Food Crisis Prevention
– Seasonal rainfall forecast (PRESAO),
– Monitoring the progress of sowing performance (Field data and Agrometeorological models),
– Monitoring the locust situation (Rainfall maps + Vegetation Indices),
– Yield forecasting (Agrometeorological models),
– Identifying risk zones (Synthesis of all the products),
– Joint pre-harvest assessment missions in the field,
– Annual consultative meeting in Early November,
– Targeting vulnerable populations.

Challenges / Future Prospects
• Some challenges with Guinea coast countries (more humid climate)• Need to upgrade monitoring tools and methods to those zones• Cloud contamination of most vegetation monitoring products• Establishment of national networks of users (AMESD)
• Capacity building at both regional and national levels (human resources, equipment)
• Derivation of other climate data from RS (surface temperatures, solar radiation, PET, soil moisture, etc…) and use as inputs to crop models
• AMESD / MESA, GMFS, etc…
Some Partnerships• Technical
