A recent UN report warns of looming 'water bankruptcy' globally, worsened by climate change. It advocates for transparent water accounting and equitable distribution. In India, Himalayan regions are experiencing snow droughts that impact water supplies.
A United Nations report released earlier this week underscores the risks to water security from pollution and unsustainable usage patterns. Climate change has intensified the crisis. Rising temperatures disrupt rainfall patterns, affect the water cycle, and retreating glaciers render river flows erratic, leading to 'whiplash' shifts between floods and dry spells. Droughts, shortages, and pollution incidents, once seeming temporary, are turning chronic in many areas, termed 'water bankruptcy' by the report.
Titled Global Water Bankruptcy, the study notes that not all basins and countries are equally impacted. Yet it aptly stresses that 'basins are interconnected through trade, migration, weather, and other key elements of nature. Water bankruptcy in one area will put more pressure on others and can heighten local and international tensions.'
The current Himalayan winter exemplifies climate-driven precipitation irregularities. Uttarakhand, Himachal Pradesh, and Jammu and Kashmir are grappling with snow droughts. Meteorologists attribute the dry spell to weakening western disturbances. The latter part of the season might be less arid, but snowfall in late January or early February offers limited benefits. Late snow melts rapidly, depriving soils of maximum moisture replenishment. In contrast, early snow melts gradually, supplying rivers with steady water. An IIT-Mandi study from last year highlighted that erratic precipitation—intensified over the past five years—affects agriculture, hydropower, and river flow timing.
Water management efforts worldwide, including in India, have historically prioritized steady supplies to households, farmers, and industry. Today, discussions increasingly cover aquifer recharging, rainwater harvesting, and water-efficient crops. Even so, prudent usage measures lag behind supply-side approaches. The UN report urges transparent water accounting, aquifer protection, enforceable extraction limits, and equity in water distribution.
