The Seasonal Agricultural Survey (SAS) is an annual survey conducted by the National Institute of Statistics of Rwanda (NISR) that measures crop production across Rwanda's three agricultural seasons: Season A (September-February, long rains), Season B (March-June, short rains), and Season C (July-September, small cool season). For each season, the survey reports four core metrics at the district level across all 30 Rwandan administrative districts: cultivated area (hectares), harvested area (hectares), average yield (kg per hectare), and total crop production (metric tonnes). Coverage spans major food crops including cereals (maize, sorghum, wheat, paddy rice), roots and tubers (cassava, sweet potato, irish potato), legumes (beans, peas, soybean, groundnuts), and bananas.
