Climate Change and Ground Water Depletion in Narnaul Block : A Geographical Analysis

Abstract

The adverse effects of climate change means changes in the physical environment, biodiversity and water resources which have significant harmful effects on the composition, spirit or productivity of natural and managed ecosystems or on the operation of socio-economic systems or on human health and welfare. Alteration in the Study area monsoonal patterns are the most important consequences of climate change that Narnaul block is going to face. Ground water is not only an essential element for survival of life but also it is an important vehicle for economic development in the south western Haryana. Over-exploitation of the underground water resources is the major problem due to climate change leading to underground water depletion in the Narnaul block, one of the major semi-arid highland basins of south western Haryana. As water demand rises rapidly, some regions of Narnaul block are extracting groundwater faster than it can recharge. Ground water levels are fast depleting in study areas due to low rainfall the agriculture is based on tube well irrigation and above 95% tube well irrigation are prevalent in the study area. Because of ground water level is declining continuously.  The study area lie  arid and semi-arid areas where low precipitation results in low or zero natural recharge, mining of fossil groundwater from aquifers depletes a non-renewable resource.  This paper focus on Groundwater depletion due to underground water extraction rates have shown to be more influential than climate change in the study areas.
