Prolonged absence of groundwater within the operating range of shallow tube-wells during the dry season is a growing concern in the area. It is anticipated that climate change will aggravate the situation in near future.This book discusses probable changes in the climate and their impacts on irrigation and groundwater resources in the area. Groundwater hydrographs are analyzed and correlated with meteorological drought, climate models are applied to project the future change of climate, changes in irrigation demands are calculated under projected climate, and the impacts of changing irrigation demand on groundwater resources are discussed. It is expected that...
