Contributing paper to Global Assessment Report on disaster risk reduction (GAR 2019).]Strategic use of groundwater-based solutions for drought risk reduction and climate resilience in Asia and beyond. Contributing paper to Global Assessment Report on disaster risk reduction (GAR 2019).

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...


Lautze, JonathanHolmatov, B.Saruchera, D.Villholth, Karen G.[Conjunctive management of surface and groundwater in transboundary watercourses: a first assessment]Conjunctive management of surface and groundwater in transboundary watercourses: a first assessment

Groundwater quantity and quality may be affected by climate change through intricate direct and indirect mechanisms. At the same time, population growth and rapid urbanization have made groundwater an increasingly important source of water for multiple uses around the world, including southern Af...
