Umakanth R, Umakanth R R


Chamarajanagara district is located in the extreme south of the Deccan plateau region of Karnataka. District groundwater availability mainly depends on weathered and fractured hard rocks and the amount of rainfall. Since surface water resources are limited throughout the district, groundwater has been the next alternative option. On account of reckless use of groundwater, there are other serious consequences is looming at large in the district. To understand the ground reality, the present study examines the Groundwater overdraft for agricultural purposes and resultant groundwater level change between 2001 to 2016. Secondly, the Utilization of Groundwater for agriculture is examined at the taluk/block level. Thirdly, Spatial and Temporal Variability of groundwater level has been mapped in GIS platform. To understand the ground reality is one of the major objectives of this paper, as such the measures that are necessary to be enforced to restore the lost water table is not included in this section of the paper.
