In Bihar, the Chandan dam has run completely dry.<\/li>\n\n\n\n<li><strong>Southern India<\/strong> has seen the steepest drop, raising concerns ahead of peak summer.<\/li>\n\n\n\n<li>Overall, the data suggests a <strong>widespread decline in water levels,<\/strong> with the risk of a <strong>summer water shortage rising, <\/strong>particularly in the south and west.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Water reservoirs<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Water reservoirs are<strong> natural or artificial storage spaces<\/strong> where water is collected and stored for future use.\n<ul class=\"wp-block-list\">\n<li>They include rivers, lakes, glaciers, groundwater aquifers, dam reservoirs, tanks, and canals.<\/li>\n\n\n\n<li>They play a crucial role in ensuring a <strong>steady supply of water for various purposes.<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Reasons for Decline in Capacity:\u00a0<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Siltation (Sediment Deposition): <\/strong>Accumulation of silt and debris reduces storage capacity over time.<\/li>\n\n\n\n<li><strong>Catchment Area Degradation: <\/strong>Deforestation, mining, and overgrazing increase soil erosion and sediment inflow.<\/li>\n\n\n\n<li><strong>Encroachment &amp; Urbanisation: <\/strong>Illegal occupation of reservoir areas and feeder channels reduces effective storage.<\/li>\n\n\n\n<li><strong>Eutrophication &amp; Aquatic Weeds: <\/strong>Nutrient pollution leads to excessive growth of algae and weeds, occupying space.<\/li>\n\n\n\n<li><strong>Climate Variability:<\/strong> Erratic rainfall and droughts reduce inflow and accelerate sedimentation.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Water scarcity in India<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>India has <strong>18% <\/strong>of the world\u2019s population but only<strong> 4% <\/strong>of its freshwater.\u00a0<\/li>\n\n\n\n<li>The World Bank calls India one of the <strong>most water-stressed countries.\u00a0<\/strong>\n<ul class=\"wp-block-list\">\n<li>Many parts of India could face <strong>severe water scarcity by 2040<\/strong> because of growing demand, poor management, and climate change.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>According to the <strong>Annual Ground Water Quality Report 2024<\/strong> by the <strong>Central Groundwater Board (CGWB)<\/strong>, the average stage of groundwater extraction in India stands at<strong> 60.4%.<\/strong><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Major Causes of Water Scarcity<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rapid urbanisation and industrialisation<\/strong> have led to increased pollution of water bodies, making them unfit for consumption.\u00a0<\/li>\n\n\n\n<li><strong>Inefficient agricultural practices and excessive groundwater extraction<\/strong> have depleted crucial water sources.\u00a0<\/li>\n\n\n\n<li><strong>Climate change <\/strong>further aggravates the situation, causing irregular rainfall patterns and affecting the recharge of rivers and aquifers.\u00a0<\/li>\n\n\n\n<li><strong>Poor water management <\/strong>and lack of proper infrastructure also play a significant role in exacerbating the crisis.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Water Governance in India<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Constitutional Provisions<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>State Subject: <\/strong>Water is primarily under <strong>Entry 17 of State List (Seventh Schedule).<\/strong><\/li>\n\n\n\n<li><strong>Union Role: <\/strong>Regulation of inter-state rivers under<strong> Entry 56 of Union List.<\/strong><\/li>\n\n\n\n<li><strong>Article 262: <\/strong>Parliament can adjudicate inter-state water disputes.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Key Issues in Water Governance in India<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fragmented Institutional Framework: <\/strong>Water governance in India is highly fragmented due to its placement in the State List, which leads to jurisdictional conflicts between states.<\/li>\n\n\n\n<li><strong>Predominance of Engineering-Centric Approach: <\/strong>Water management policies in India have historically focused on large-scale infrastructure such as dams, canals, and irrigation systems.\n<ul class=\"wp-block-list\">\n<li>This approach prioritises supply augmentation while neglecting ecological sustainability and demand management.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Agricultural Policies: <\/strong>Agricultural policies promoting water-intensive crops such as rice and wheat have led to excessive groundwater extraction.<\/li>\n\n\n\n<li><strong>Lack of Ecosystem-Based Approach: <\/strong>Water governance does not adequately incorporate the interlinkages between land, water, and ecosystems.\n<ul class=\"wp-block-list\">\n<li>Environmental flows (e-flows) are often ignored, leading to degradation of rivers and wetlands.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Weak Data Systems: <\/strong>There is a lack of reliable, comprehensive, and accessible water data across the country.\n<ul class=\"wp-block-list\">\n<li>This leads to poor planning, inefficient allocation, and unregulated extraction of water resources.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Neglect of Demand-Side Management:<\/strong> Water policies largely focus on increasing supply rather than managing demand.\n<ul class=\"wp-block-list\">\n<li>Limited attention is given to water-use efficiency, conservation practices, and rational pricing.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Upcoming concerns: <\/strong>India&#8217;s data centre boom confronts a water challenge as predictions state that 60\u201380% of India\u2019s data centres will face high water stress this decade.\n<ul class=\"wp-block-list\">\n<li>Most of these centres are built in cities such as Mumbai, Chennai, Hyderabad, and Bengaluru, places where water is already in short supply.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Government Initiatives<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Jal Shakti Abhiyan (2019):<\/strong> Focuses on water conservation and groundwater recharge in water-stressed districts.<\/li>\n\n\n\n<li><strong>AMRUT 2.0 scheme<\/strong> was launched in the 2021 in all Urban Local Bodies (ULBs)\/ cities, enabling the cities to become &#8216;self-reliant&#8217; and &#8216;water secure&#8217;.\n<ul class=\"wp-block-list\">\n<li>Rejuvenation of water bodies and development of green spaces and parks are other components of the mission.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Amrit Sarovar Mission:<\/strong> Aims to develop and rejuvenate 75 water bodies per district.<\/li>\n\n\n\n<li><strong>National Aquifer Mapping Program (NAQUIM): <\/strong>Helps delineate and understand aquifers for sustainable management.<\/li>\n\n\n\n<li><strong>Atal Bhujal Yojana<\/strong>, was launched to improve groundwater management in priority areas with critical and overexploited blocks.<\/li>\n\n\n\n<li><strong>Jal Jeevan Mission (JJM):<\/strong> To enable every rural household in the country to have assured potable water; since 2019, Government in partnership with states, is implementing Jal Jeevan Mission (JJM).\n<ul class=\"wp-block-list\">\n<li>This initiative facilitates adequate quantities of prescribed quality water on a regular and long-term basis, through tap water connection.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>There is a need to move from a <strong>fragmented and engineering-dominated approach <\/strong>to a comprehensive governance framework.<\/li>\n\n\n\n<li>Water must be treated as a shared and finite resource, requiring coordinated management across sectors.<\/li>\n\n\n\n<li>The focus should shift from <strong>supply augmentation to sustainability, efficiency, and equity.<\/strong><\/li>\n<\/ul>\n\n\n\n<p><strong>Source: <\/strong><a
