%X In Sahelian countries, the development of irrigated agriculture is one of the solutions to avoid repetitive food crises. Considering south-western Niger as a regional case study, this paper demonstrates that increasing low-cost groundwater irrigation represents a long-term solution, using shallow, unconfined perennial groundwater, widely distributed in this region. Groundwater resources and soil characteristics were described and localized in space, quantified in volume and/or surface area, and their long-term potential estimated as a function of updated datasets. Data analysis demonstrates that similar to 50,000 to 160,000 ha (3 to 9% of present-day cultivated areas) could be turned into small irrigated fields using accessible shallow groundwater (water table depth <= 20 m). This would double the regional capacity for irrigation.
