Strategies for increasing the development and use of groundwater for agriculture over much of Sub-Saharan Africa (SSA) are urgently needed. Expansion of small-scale groundwater irrigation offers an attractive option to smallholder farmers to overcome unreliable wet-season rainfall and enhance dry...

Sun, R.Jin, M.Giordano, MarkVillholth, Karen G.[Urban and rural groundwater use in Zhengzhou, China: challenges in joint management]Urban and rural groundwater use in Zhengzhou, China: challenges in joint management

Groundwater is an important resource for multiple uses in South Africa. Hence, setting limits to its sustainable abstraction while assuring basic human needs is required. Due to prevalent data scarcity related to groundwater replenishment, which is the traditional basis for estimating groundwater...


Ebrahim, Girma YimerVillholth, Karen G.[Estimating shallow groundwater availability in small catchments using streamflow recession and instream flow requirements of rivers in South Africa]Estimating shallow groundwater availability in small catchments using streamflow recession and instream flow requirements of rivers in South Africa

Cooperative management of transboundary river basins is widely recognized as important. Emphasis on joint management of shared aquifers has also grown in recent years. Perhaps surprisingly, despite abundant focus on transboundary surface water and growing focus on shared groundwater, there is sca...

Groundwater provides an important buffer to climate variability in Africa. Yet groundwater irrigation contributes only a relatively little share of cultivated land, approximately 1% (about 2 million hectares) as compared to 14% in Asia. While groundwater is over-exploited for irrigation in many p...

Recent attention to transboundary aquifers (TBAs) in Africa reflects the growing importance of these resources for development in the continent. However, relatively little research on these aquifers and their best management strategies has been published. This report recapitulates progress on map...


Altchenko, YvanVillholth, Karen G.[Transboundary aquifer mapping and management in Africa: a harmonised approach]Transboundary aquifer mapping and management in Africa: a harmonised approach

The abundance of groundwater resources of Sub-Saharan Africa is generally well recognized, but quantitative estimates of their potential for irrigation development are lacking. This study derives estimates using a simple and generic water balance approach and data from secondary sources for 13 co...
