    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.

    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

    transboundary rivers, upstream and downstream conflicts emanating from the development and
