Climate variability and change is regarded as having major impacts on key sustainable socio-economic and environmental indicators in Sub-Saharan West Africa. Because of these concerns, we investigated smallholders knowledge, skills, and aspirations about managing climate change, and document adaptation strategies used in the semi-arid regions coming from Burkina Faso, Chad and Niger. We analyzed climate data from the 1950’s to the present, including daily and aggregated rainfall and temperature variability, trends and extremes.

Sahelian Africa faces a persistent problem of variability in rainfall, which is the major driver of vulnerability in the region. Populations in the Sahel are among the poorest and most vulnerable to climatic variability and land degradation. They depend heavily on healthy ecosystems for rainfed agriculture, fisheries, and livestock management to sustain their livelihoods. These constitute the primary sectors of employment in the region and they generate at least 40 percent of the gross domestic product (GDP) in most of the countries. Furthermore, ecosystem services provide much needed livelihood products, such as fuelwood and bushmeat, among others. Unfortunately, increasing population pressures on food, fodder, and fuelwood in a vulnerable environment have deteriorating impacts on natural resources, notably vegetation cover. Climate variability along with frequent droughts and poorly managed land and water resources (surface and underground) have caused rivers and lakes to dry up and contribute to increased soil erosion.

The 2024 Edition of the PRESASS was organized from April 22 to 26, 2024 in Abuja, Nigeria, by AGRHYMET Regional Climate Center for West Africa and the Sahem (AGRHYMET RCC-WAS) of the CILSS, in collaboration with ACMAD, the National Meteorological and Hydrological Services (NMHSs), WMO and the West African River Basin Organizations. .......Generally a wet rainy season is expected in 2024 over the Sahelian belt, with late to normal starting dates of the agricultural season in the Sahel-Central and early to normal s in the Sahel-West and East; late to normal ending dates of the agricultural season; short dry spells at the beginning of the season in the Sahel-West and medium to long dry spells in the Sahel-East and generally long dry spells towards the end of the season over the entire Sahelian belt; and above-average runoff in the main Sahelian river basins.......
