Groundwater is Africa's most precious natural resource, providing reliable water supplies for many people. Further development of groundwater resources is fundamental to increasing access to safe water across the continent to meet coverage targets and reduce poverty. There is also an increasing interest in the use of groundwater for irrigated agriculture as the climate becomes more variable. Sustainable development of the resource is not a trivial task and depends crucially on an understanding of the hydrogeology and people with the skills to make informed decisions on how groundwater can best be developed and managed in a sustainable fashion. Despite these obvious needs, however, little attention has been paid to the systematic gathering of information about groundwater resources in the past few decades, with the result that data are patchy, knowledge is limited and investment is poorly targeted.This book was written to start to bridge the knowledge gap. The 29 chapters are written by a combination of practitioners and researchers mainly from within Africa using experience from recent and ongoing projects. The chapters highlight the complexity and variety of issues surrounding the development and management of groundwater resources across Africa, and provide a snapshot of groundwater research and application in the early 21st century. Chapters range from strategic discussions of the role of groundwater in development and poverty reduction, to case studies on techniques used to develop groundwater, and modelling methods for managing groundwater systems.

Aquifer natural recharge estimations are a prerequisite for understanding hydrologic systems and sustainable water resources management. As meteorological data series collection is difficult in arid and semiarid areas, satellite products have recently become an alternative for water resources studies. A daily groundwater recharge estimation in the NW part of the Lake Chad Basin, using a soil–plant-atmosphere model (VisualBALAN), from ground- and satellite-based meteorological input dataset for non-irrigated and irrigated land and for the 2005–2014 period is presented. Average annual values were 284 mm and 30°C for precipitation and temperature in ground-based gauge stations. For the satellite-model-based Lake Chad Basin Flood and Drought Monitor System platform (CHADFDM), average annual precipitation and temperature were 417 mm and 29°C, respectively. Uncertainties derived from satellite data measurement could account for the rainfall difference. The estimated mean annual aquifer recharge was always higher from satellite- than ground-based data, with differences up to 46% for dryland and 23% in irrigated areas. Recharge response to rainfall events was very variable and results were very sensitive to: wilting point, field capacity and curve number for runoff estimation. Obtained results provide plausible recharge values beyond the uncertainty related to data input and modelling approach. This work prevents on the important deviations in recharge estimation from weighted-ensemble satellite-based data, informing in decision making to both stakeholders and policy makers.

Groundwater for Sustainable Livelihoods and Equitable Growth explores how groundwater, often invisibly, improves peoples’ lives and livelihoods. This unique collection of 19 studies captures experiences of groundwater making a difference in 16 countries in Africa, South America and Asia. Such studies are rarely documented and this book provides a rich new collection of interdisciplinary analysis. The book is published in colour and includes many original diagrams and photographs.
Spring water, wells or boreholes have provided safe drinking water and reliable water for irrigation or industry for millennia. However, the hidden nature of groundwater often means that it’s important role both historically and in the present is overlooked. This collection helps fill this knowledge gap, providing a diverse set of new studies encompassing different perspectives and geographies. Different interdisciplinary methodologies are described that can help understand linkages between groundwater, livelihoods and growth, and how these links can be threatened by over-use, contamination, and ignorance.
Written for a worldwide audience of practitioners, academics and students with backgrounds in geology, engineering or environmental sciences; Groundwater for Sustainable Livelihoods and Equitable Growth is essential reading for those involved in groundwater and international development.
