The study was carried out in the Jodhpur district of Rajasthan which represents a major part of India's hot arid region and historically, a dryland practicing mainly rainfed agriculture. Authors used remote sensing techniques and GIS for a spatial analysis of irrigated croplands and ground water levels and mapped decadal changes for the years 2000, 2010 and 2020. Results showed a significant increase in the extent of irrigated crop area (7.56% in the year 2000-21.26% during 2020) and a lowering of ground water level in three of the most agriculturally prosperous tehsils; Osian (- 36.02 m), Shergarh (- 11.38 m) and Phalodi (- 44.85 m). Considering the fact that in Rajasthan, > 90% blocks are classified as Groundwater dark zone, such practices will have a broader implication in the seasonal cropping pattern.
