    Smallholder shallow groundwater irrigation development in the upper east region of Ghana
    (Report, 2011) Namara, Regassa E.; Awuni, J.A.; Barry, Boubacar; Giordano, Mark; Hope, Lesley; Owusu, Eric S.; Forkuor, Gerald
    In Sub-Saharan Africa, there is paucity of information on the potential of groundwater resources. The limited available information paints a pessimistic view about groundwater resources. Due to its perceived inadequate availability, groundwater associated with domestic use and the potential for using it for agriculture are not well reflected in the national irrigation polices. Contrary to official pessimism, farmers do use groundwater for agriculture in many countries of Sub-Saharan Africa including Ghana. This paper analyzes the current extent of use, economics, socioeconomic impacts, and constraints and opportunities of shallow groundwater irrigation based on the experiences of smallholders in the three micro-watersheds of the White Volta Basin in the Upper East Region of Ghana.

    Shallow groundwater in the Atankwidi Catchment of the White Volta Basin: current status and future sustainability
    (Report, 2010) Barry, Boubacar; Kortatsi, B.; Forkuor, Gerald; Gumma, Murali K.; Namara, Regassa E.; Rebelo, Lisa-Maria; Berg, J. van den; Laube, W.
    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.

    Contribution of informal shallow groundwater irrigation to livelihoods security and poverty reduction in the White Volta Basin (WVB): Current status and future sustainability
    (Report, 2010-05-15) Barry, Boubacar; Forkuor, Gerald
    Shallow groundwater irrigation (SGI) using hand-dug shallow wells and dugouts is expanding, in the WVB, and is becoming attractive to farmers throughout. SGI is farmer-driven and has developed without any government or donor involvement. The production of vegetables and cash crops during the dry season utilizing SGI has provided farmers with a supplemental source of income and an alternative to seasonal urban migration. Although SGI has been increasing substantially, the extent of this practice is not documented.This project has help assess, the impacts of intensive SGI on sub-basin hydrology, net groundwater recharge farmers' livelihoods and on rural poverty reduction in the Atankuidi catchment a tributary of the WVB with the highest per capita groundwater use.
