Significant drop in the volume of Ganga river water and groundwater in the river basin, reveals WMO report

As per a report by the World Meteorological Organisation (WMO), titled State of Global Water Resources 2021, the volume of water available in the Ganga and the groundwater in the river basin have both seen a significant fall between 2002 and 2021. While Ganga is not the only river basin, the report has identified several other global hot spots that show the same trend as Ganga, including the São Francisco River basin, in Patagonia, the Indus headwaters, and basins in south-western US. However, the Great Lakes region, has seen a positive trend, as have the Niger basin, and the North Amazon basin but overall, the negative trends are stronger than the positive ones globally.

Drier than normal conditions in 2021 as rainfall patterns were influenced by climate change and a La Niña event and over-extraction of groundwater for irrigation are attributed to be the cause of the alarming trend.

A new lease of life for Dal Lake as the government is opening 20 navigation channels after decades

After decades, the government of Jammu & Kashmir is opening 20 navigation channels in the Dal Lake, with an aim to improve the quality of water in the lake and free movement of locals and tourists into the interiors of the lake.

The opening of the navigation channels will not only allow the inhabitants to move freely but also improve the quality of lake water as these channels help the water to circulate.

Along with this, there are plans to lay a sewage system for the houseboats to dispose of the waste in the treatment plant. Sewage coming from the houseboats is one of the major pollutants for the lake, with more than 600 houseboats on the lake, there has not been a proper sewage system in place for these houseboats for decades, however, the new sewerage system will help clean the lake and to nurture the aquatic life in the lake.
