520    This book provides a comprehensive description of 
       groundwater resources in Ethiopia and its various 
       dimensions (groundwater as resource, environmental 
       functions, and socioeconomics). The prevailing knowledge 
       of groundwater resources in Ethiopia (or elsewhere in Sub 
       Saharan Africa) was based on geological and stratigraphic 
       framework known nearly four decades ago (mainly 1960's and
       70's). Thanks to the substantial geoscientific research 
       since the 70's a new set of relevant geological/
       stratigrahpic data has been created that helps to re-
       define our understanding of groundwater resources in 
       Africa as a whole and in Ethiopia in particular: a) For 
       the first time the basement aquifer of Ethiopia has been 
       described hydrogeologically based on genesis of regoliths 
       (deep weathering and striping history); clear regional 
       difference in groundwater potential is shown for the first
       time; comparative accounty has been given regarding 
       groundwater occurrence in the generally low grade basement
       rocks of Ethiopia (Arabian Nubian shield) and high grade 
       basement rocks of the rest of Africa. b) For the first 
       time groundwater occurrence in multilayred sedimentary 
       rocks account for spatial variation in degree of 
       karstification; deformation history, and stratigraphy. c) 
       The vast volcanic aquifers of Ethiopia which have 
       previously classified based on their ages are now 
       reclassified based on age, morphology (eg. groundwater in 
       plateau volcanics, groundwater in shield volcanics) and 
       aquifer structure. d) The loose alluvio lacustrine 
       sediments which were known as least extensive in previous 
       works based on areal cover are in fact shown to host the 
       most voluminous groundwater resources in Ethiopia. These 
       aquifers have now been described based on their 
       geomorphology, extent, and genesis. The aim of this book 
       is to use these newly created knowledge to redefine the 
       understanding of groundwater resources in Ethiopia.
