Preliminary results from a Water Economy and Livelihoods Survey (WELS) in Nigeria and Mali, sub-Saharan Africa: Investigating water security across a rainfall transect
- DFID-DJ Lapworth, AM MacDonald, H Bonsor, MN Tijani, and RC Calow
In 2010 the Department for International Development (DFID) commissioned a BGS-led team to undertake a one-year study aimed to improve understanding of the resilience of groundwater in Africa to climate change and links to livelihoods. As part of this project, the research team undertook hydrogeological field studies in West and East Africa, examined the linkages between water use and household economy, and developed an aquifer resilience map for Africa using existing hydrogeological maps and data. This is one of a series of technical notes which describes the studies carried out by the research team as part of this project. This report describes the methodology and preliminary results from a simplified water, economy and livelihoods survey (WELS) carried out in West Africa at the same time as a groundwater residence survey (which is reported separately). Results from community discussions are presented for four case study areas in a transect across humid to semi arid conditions in Nigeria and Mali.
