Determining groundwater sustainability from long-term piezometry in Sub-Saharan Africa

Submission status
Closed

This collection is constituted by five articles that present new evidence on the sustainability of groundwater use in Sub-Saharan Africa. Groundwater withdrawal is a potential strategy to meet rapid increases in freshwater demand that are projected to secure food supplies through irrigation and to realise universal access to safe water. As climate change amplifies the extreme variabilities (rainfall, surface-water resources) that characterise Sub-Saharan Africa, groundwater use alone or in conjunction with surface water may prove the only climate-resilient solution to realise these ambitions by 2030, as enshrined in UN Sustainable Development Goals 2 and 6. The articles present newly compiled observations of long-term groundwater-level records and satellite data to assess the sustainability of groundwater systems in Sub-Saharan Africa.
