Impact Of Climate Change On Water Resources Of India

Abstract

A significant anthropogenic hazard to the global environment is climate change. Climate change's direct and indirect effects will be detrimental to regional agriculture, food security, human systems, and water resources. With only 4% of the world's water resources and around 9% of the world's arable land, India, which has a population of more than 1.2 billion, has witnessed unprecedented economic growth in the last two decades. The need for water has grown significantly throughout time as a result of population growth, expanded agriculture, fast industrialisation, urbanisation, and economic growth. In addition, uncontrolled use of surface and groundwater resources, careless disposal of industrial and municipal waste, and the use of agricultural inputs have all contributed to the issue of water quality degradation and contamination, creating additional difficulties for water management and conservation. A warmer climate may cause the hydrological cycle to intensify, causing higher rates of evaporation and more liquid precipitation.  The hydrological cycle is now being altered quantitatively and/or qualitatively across the majority of India's agroclimatic regions and river basins due to human activities including altered cropping patterns, changes in land use patterns, overuse of water storage, irrigation, and drainage. Given the foregoing, sustainable management of water resources and the surrounding environment has become increasingly important in recent years. For appropriate national and regional long-term development strategies and sustainable development, it is essential to assess the availability of water resources in the context of future national requirements, paying particular attention to the growing demands for water and anticipated impacts of climate change and variability. It is necessary to take action to safeguard water supplies and reduce the factors contributing to climate change and its negative effects..
