But these pleasant recollections are now just distant memories. Rivers in Asia are in a <a href=\"https:\/\/dialogue.earth\/2019\/02\/12\/water-dangers-loom-for-south-asia\/\">dire state<\/a>.<br><br>While <a href=\"https:\/\/dialogue.earth\/2019\/04\/22\/photo-feature-ganga-back-to-dirty-ways\/\">pollution<\/a> is the most visible symptom of river ill health, the issue of their anaemic flow is far greater and, prior to the past two years, has been mostly ignored.<br><br>Many rivers have been depleted by excessive abstraction for irrigation, industry and human consumption. Basin water tables have fallen as supply-side-oriented administrations rapaciously suck the life-giving waters from them. In addition, rivers are increasingly bearing the brunt of climate change as rainfall becomes erratic in their basins or, in the case of snow-fed rivers, glaciers retreat.<br><br>The Indus, Ganga and Brahmaputra rivers are sub-continental rivers which are both snow-fed and dependent on tributaries. They are all transboundary rivers and, even within their countries, flow through several administrative jurisdictions. These conditions throw up titanic challenges in developing basin management plans and governance structures.<br><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<a class=\"wp-block-cd-related-news alignright block--related-news loading\" data-post-id=\"20027362\"><div class=\"block--related-news__image\"><\/div><div class=\"block--related-news__content\"><span class=\"block--related-news__heading\">Recommended<\/span><span class=\"block--related-news__title\"><\/span><\/div><\/a>\n\n\n\n<p><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<a class=\"wp-block-cd-related-news block--related-news loading\" data-post-id=\"20034678\"><div class=\"block--related-news__image\"><\/div><div class=\"block--related-news__content\"><span class=\"block--related-news__heading\">Recommended<\/span><span class=\"block--related-news__title\"><\/span><\/div><\/a>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\"><\/div>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-visible-pollution-problem\">Visible pollution problem<\/h2>\n\n\n\n<p>Pollution has degraded many of the region\u2019s rivers. There are known technical solutions, such as sewage and effluent treatment plants, pumping stations and solid waste management, addressing the problems of chemical and organic pollution as well as plastics.<br><br>Moreover, investors are keen to dedicate capital to solving this problem, and it can be overcome in a relatively short time horizon. Therefore, the ruling establishment class of big business,\u00a0state government, central government, regulators and so on has become more serious about addressing river pollution by using capital-intensive technology.<br><br>Despite this encouraging momentum, the problem has grown very large and is still expanding, and the amount of finance is limited. When solutions are implemented it is with limited success.<br><br>For example, Delhi alone has about 30% of India\u2019s sewage treatment plant capacity but the <a href=\"https:\/\/dialogue.earth\/2020\/05\/08\/in-multimedia-will-a-resurrected-yamuna-stay-alive\/\">Yamuna river is far from clean<\/a>. Likewise the <a href=\"https:\/\/dialogue.earth\/2019\/04\/22\/photo-feature-ganga-back-to-dirty-ways\/\">Ganga<\/a>, despite being India\u2019s national river with vast funding poured into treatment infrastructure, is still one the <a href=\"https:\/\/dialogue.earth\/ganga-an-unholy-mess\/\">most polluted rivers<\/a> in the world.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-less-attention-to-flow\">Less attention to flow<\/h2>\n\n\n\n<p>On the other hand, little attention has been paid to depleted and dry rivers, despite a relation to pollution. If there is less water compared to the amount of pollution, the river will, perforce, be more polluted. Only in the past few years have persistent efforts by NGOs begun to register with governments. Also, as governments try to <a href=\"https:\/\/dialogue.earth\/2017\/11\/09\/indias-national-waterways\/\">develop waterways<\/a> they are starting to realise the problem as projects are constrained by the inadequate flow.<br><br>The <a href=\"https:\/\/dialogue.earth\/2016\/09\/15\/cauvery-dispute-dismays-indias-neighbours\/\">Cauvery river<\/a> in south India, for example, does not flow to the sea most of the year, aggravating the problem of saltwater intrusion in its delta. The Yamuna is almost dry for most of its course downstream of Hathnikund Barrage in the summer, and is anaemic until its confluence with the life-restoring Chambal.<br><br>The restoration of river flow is, therefore, the real challenge. It is only possible to rejuvenate and conserve rivers by prudent management of their basins \u2013&nbsp;and it can take decades to show results, especially as the dynamics of climate change play out. India\u2019s <a href=\"http:\/\/mowr.gov.in\/policies-guideline\/policies\/national-water-policy\">National Water Policy<\/a> over the years has stressed the need for river basin management, but the idea has never really taken off.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-misguided-interventions\">Misguided interventions<\/h2>\n\n\n\n<p>Over time, powerful state water bureaucracies, or hydrocracies, have taken control of the region\u2019s intrastate and interstate rivers. These establishments view rivers only as a water resource rather than living ecosystems and thrive on the business of extracting and diverting water by building dams, barrages and canals.<br><br>India has 14 major rivers (basin area exceeding 20,000 square kilometres), 42 medium rivers (basin between 2,000-20,000 sq km) and 55 minor rivers (basin less than 2,000 sq km). There are also thousands of local streams, rivulets and drainage courses.<br><br>The critical state of rivers, from the first-order stream to the highest-order river, has inspired environmental activists and riverine communities to protect and revive rivers and streams. But a lack of understanding about river basins has led to misguided approaches. While some believe in deepening river beds through excavation (resulting in temporary rain-fed pools rather than flowing water), others believe in planting trees in riparian zones (the area between a river or stream and the land), draining ground water flow that would otherwise join the river.<\/p>\n\n\n\n<div class=\"wp-block-cd-article-image aligncenter block--article-image\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><div class=\"block--article-image__column\"><div class=\"block--article-image__image\"><img class=\"lazy\" data-src=\"https:\/\/dialogue.earth\/content\/uploads\/2020\/11\/river-basin-diagram-showing-watershed-line-and-connection-with-groundwater-INTACH-1.jpg\" data-srcset=\"https:\/\/dialogue.earth\/content\/uploads\/2020\/11\/river-basin-diagram-showing-watershed-line-and-connection-with-groundwater-INTACH-1.jpg 441w\" data-sizes=\"(max-width: 600px) 768px, (max-width: 1024px) 1024px, 441px\" alt=\"river basin diagram showing watershed and connection with groundwater labelled \"\/><\/div><div class=\"block--article-image__content\"><div itemprop=\"caption\" class=\"block--article-image__caption\"><em>Image by: INTACH<\/em><\/div><\/div><\/div><meta itemprop=\"contentUrl\" content=\"https:\/\/dialogue.earth\/content\/uploads\/2020\/11\/river-basin-diagram-showing-watershed-line-and-connection-with-groundwater-INTACH-1.jpg\"\/><meta itemprop=\"contentSize\" content=\"80 KB\"\/><meta itemprop=\"height\" content=\"424\"\/><meta itemprop=\"width\" content=\"441\"\/><meta itemprop=\"author\"\/><meta itemprop=\"representativeOfPage\" content=\"true\"\/><\/div>\n\n\n\n<p>This is complicated by the fact that extensive data is only available on only larger rivers.

It is subtracted from \u2018revenue\u2019, or precipitation which transforms into surface water, groundwater, soil moisture and evaporation. The calculation then informs policy choices that focus on attaining and maintaining flowing rivers.<\/p>\n\n\n\n<div class=\"wp-block-cd-article-image aligncenter block--article-image\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><div class=\"block--article-image__column\"><div class=\"block--article-image__image\"><img class=\"lazy\" data-src=\"https:\/\/dialogue.earth\/content\/uploads\/2020\/11\/INTACH-flowchart-water-budget-1.png\" data-srcset=\"https:\/\/dialogue.earth\/content\/uploads\/2020\/11\/INTACH-flowchart-water-budget-1.png 510w\" data-sizes=\"(max-width: 600px) 768px, (max-width: 1024px) 1024px, 510px\" alt=\"water budget flowchart showing inflow\/resources and outflow\/expenditure\"\/><\/div><div class=\"block--article-image__content\"><div itemprop=\"caption\" class=\"block--article-image__caption\"><em>INTACH\u2019s flowchart illustrating the major components of a water budget<\/em><\/div><\/div><\/div><meta itemprop=\"contentUrl\" content=\"https:\/\/dialogue.earth\/content\/uploads\/2020\/11\/INTACH-flowchart-water-budget-1.png\"\/><meta itemprop=\"contentSize\" content=\"154 KB\"\/><meta itemprop=\"height\" content=\"491\"\/><meta itemprop=\"width\" content=\"510\"\/><meta itemprop=\"author\"\/><meta itemprop=\"representativeOfPage\" content=\"true\"\/><\/div>\n\n\n\n<p>In a case study on the Hindon basin, INTACH calculated the large mismatch between the basin\u2019s resources and the amount of water being used.

The BMOs would cut across administrative\u00a0boundaries which presently do not coincide with basin boundaries.<br><br>It is very much a work in progress. Bureaucracies offer tough resistance when they see their powers being diluted, and complexities arise when rivers are interstate and\/or transboundary.<br><br>Improving the flows of tributaries will enhance flows in higher-order streams.
