Good local hydrogeological understanding and monitoring over time is required to define the sustainable yield of wells and boreholes, particularly in weathered basement aquifers, and from this assess opportunities for domestic, agricultural, commercial and industrial activities, and the associated risks.…

UPGro Science: understanding of African/Tropical recharge processes has been improved. Climate change may enhance groundwater recharge in arid and semi-arid areas, presenting opportunities for long-term management as part of national climate adaptation strategies [S4]
UPGro researchers found that in wetter areas recharge happens every year, but in dryland areas substantial recharge less regularly, often just once or twice a decade.
UPGro Science: Testing of shallow groundwater in urban areas confirmed widespread contamination and health risks, and some contaminants not previously detected or tested for. New sensor methods developed [S8]
https://youtu.be/dkAPbYJGhFE In urban areas, groundwater quality measured in Ghana, Uganda, Tanzania, Kenya and Zambia was found to be generally poor, particularly in shallow unconfined aquifers. Viral DNA work shows that viruses, some of which are pathogenic and carcinogenic for humans,…
UPGro Science: Access to groundwater is associated with improved agricultural production, reduced agricultural risk, and improved livelihoods [S11]
Access to groundwater is associated with improved agricultural production, reduced agricultural risk, and improved livelihoods.
