Increasing climate variability makes it difficult for farmers to know what to grow and when. To help farmers plan their cropping calendars, the national meteorological agency in Senegal has worked with farmers to develop accurate and region-specific seasonal rainfall forecasts. The forecast information includes estimates of total seasonal rainfall, the onset and end of the rainy season, plus 10-day forecasts during the rainy season. This information is conveyed to farmers in formats that are tailored to meet their needs, helping farmers to make crucial management decisions despite increasing climate variability. After successful pilots in one region, the geographical scope of forecasts has now been widened through a partnership with Senegal’s Union des Radios Associatives et Communautaires (URAC), an association of 73 community-based radio stations promoting economic development through communication and local information exchange. The interactive nature of the radio program allows listeners to respond with additional information, views and requests for clarification. By making well-informed decisions, farmers can maintain production and prevent unexpected losses during extreme weather events. Seasonal and 10-day forecasts also help farmers cope with increasing rainfall variability by adjusting decisions — most importantly the timing of planting — at short notice (CCAFS 2014b, 14 Ndiaye et al. 2013 15).
