Rainfed agriculture is the most dominant activity, covering 60-70% of the watershed, but suffers from low yields and high climatic risk. Irrigated gardening provides higher financial returns, with up to 90% of harvests sold, though it faces challenges from dam siltation and pesticide pollution. Pastoralism serves as a critical financial safety net, though grazing lands are being reduced by the expansion of Ouagadougou and agri-business. Fishing is a minor activity involving less than 3% of the population, threatened by invasive plants and non-compliant fishing nets.","ai_generated":true,"unit":"sei-001483#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Rainfed agriculture is the primary livelihood strategy, occupying 60 to 70 per cent of the Nariarlé watershed.
