Groundwater recharge in Africa: identifying critical thresholds

New groundwater maps reveal interesting patterns about water security in Africa that could help it adapt to climate change

Reserves of groundwater in much of the populated parts of Africa are being replenished at rates that could help to protect communities against the damaging effects of climate change and sustain widespread groundwater pumping for drinking water, a new study reveals. Researchers estimate that the long-term groundwater recharge in Africa is approximately 15,000 km3 (cubic…

:: New UPGro paper :: Characteristics of high-intensity groundwater abstractions from weathered crystalline bedrock aquifers in East Africa

Maurice, L., Taylor, R.G., Tindimugaya, C. et al. Characteristics of high-intensity groundwater abstractions from weathered crystalline bedrock aquifers in East Africa Hydrogeol J (2018). https://doi.org/10.1007/s10040-018-1836-9 From the GroFutures Consortium project and Groundwater Recharge Catalyst project Background Crystalline Bedrock aquifers underlie about 40% of Sub-Saharan Africa and can generally sustain low-intensity abstraction. However, pumping rates and dependency is increasing…
