Groundwater recharge is the enhancement of natural ground water supplies using man-made conveyances such as infiltration basins, trenches, dams, or injection wells. Aquifer storage and recovery (ASR) is a specific type of groundwater recharge practiced with the purpose of both augmenting ground water resources and recovering the water in the future for various uses.
Climate change considerations
- More storage capacity needed to overcome seasonal dry periods and to reduce floods.
- Higher rainfall intensities may exceed infiltration capacities. Create storage, enhanced infiltration or artificial recharge.
- Lower rainfall results in the need for transport and storage of water from other areas.
- Changes in vegetation will cause changes in evapotranspiration, surface runoff, erosion and sediment transport/deposition. This requires water and soil conservation measures, like terracing.

- Africa Groundwater Literature Archive: The Archive is a searchable database of published and unpublished groundwater literature about Africa, including reports, journal articles, conference papers and maps. Many of these documents are freely available to download; for others, a link is provided to the online abstract, or a full bibliographic reference is given where the document is not known to be available online.
