Groundwater is critical to global water security. This was the clear message Professor Richard Taylor delivered at a seminar in Oxford on 13 November. Water stored underground provides around 36% of the world’s domestic supplies, and 42% of all irrigation water. Use of groundwater could also prove a useful adaptation to climate variability and change.
Professor Mike Edmunds – expert in geology and groundwater management at the School of Geography and the Environment – comments on a recent British Geological Survey publication on groundwater in Africa. He questions the assumption that groundwater is an abundant new resource in Africa and higlights several limitations to its availability.
