By Segun Adelana, Alan MacDonald

Groundwater is Africa’s most valuable common source, delivering trustworthy water offers for plenty of people.  extra improvement of groundwater assets is key to expanding entry to secure water around the continent to satisfy assurance ambitions and decrease poverty. there's additionally an expanding curiosity within the use of groundwater for irrigated agriculture because the weather turns into extra variable.  Sustainable improvement of the source isn't really a trivial activity and relies crucially on an knowing of the hydrogeology and folks with the talents to make expert judgements on how groundwater can top be constructed and controlled in a sustainable type. regardless of those visible wishes, notwithstanding, little awareness has been paid to the systematic accumulating of knowledge approximately groundwater assets some time past few a long time, with the outcome that information are patchy, wisdom is proscribed and funding is poorly targeted. 
This booklet used to be written to begin to bridge the information hole. The 29 chapters are written by way of a mixture of practitioners and researchers normally from inside of Africa utilizing event from fresh and ongoing projects.  The chapters spotlight the complexity and diversity of concerns surrounding the improvement and administration of groundwater assets throughout Africa, and supply a photo of groundwater learn and alertness within the early twenty first century.  Chapters variety from strategic discussions of the position of groundwater in improvement and poverty relief, to case reports on innovations used to advance groundwater, and modelling tools for dealing with groundwater systems.

Bevan Independent Water and Sanitation Consultant, Cambridge, UK Nearly half of the population of Sub-Saharan Africa is in a state of severe and chronic poverty. Lack of access to safe domestic water, and indeed to significant quantities of water for other productive uses, defines and contributes to that poverty.

The Basement rocks store groundwater in the upper weathered regolith. The regolith can vary in thickness from a few metres in desert areas up to 90 m in the more humid tropics. The second most significant hydrogeological domain is of consolidated sedimentary rocks such as sandstones and limestones (32% of the land area), containing substantial reserves of groundwater, and sustaining a rural population of approximately 110 million. Aquifers in these rock types are often productive and may be exploited to support urban populations in addition to rural crop production and livestock watering.
