Groundwater resources development and planning in the semi arid region This book addresses the various challenges in achieving sustainable groundwater development management and planning in semi arid regions with a focus on India and discusses advanced remote sensing and GIS techniques for the estimation and management of groundwater resources. The book is timely as there is a need for a better understanding of the various tools and methods required to efficiently and sustainably meet the growing demand for clean surface and groundwater in developing countries and how these tools can be combined with other strategies in a multi disciplinary fashion to achieve this goal in water scarce regions. To wit the book combines remote sensing and GIS techniques runoff modeling aquifer mapping land use and land cover analyses evapotranspiration estimation crop coefficients and water policy approaches. This will be of use to academics policymakers social scientists and professionals involved in the various aspects of sustainable groundwater development planning and management.
