Water scarcity is a significant challenge in Burkina Faso, especially for irrigated farmers who rely on surface water sources such as rivers and ponds. A mixed-methods approach combining quantitative survey data with qualitative interviews to assess the effectiveness and cost-effectiveness of different water harvesting technologies among a sample of 120 irrigated farmers. Farmers who adopted rainwater harvesting systems reported an average annual savings of 35% in irrigation water costs, translating into 48 per hectare. Water harvesting systems have the potential to significantly reduce water usage and increase economic benefits for irrigated farmers in Burkina Faso. Government policies should incentivize the adoption of water harvesting technologies through subsidies and public awareness campaigns.
