The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas.

The Niger River Basin covers 7.5% of the African continent, and is shared between nine riparian
countries. The basin countries can be categorized into water resources producers, consumers, both
producers and consumers, and minimum contributors and consumers. As in the case for most
