Water use across US has been decreasing since 2005, has now reached pre 1970 levels, says the U.S. Geological Survey (USGS) study[i] published on June 19, 2018. According to a new USGS report[ii], 445 BCM (Billion Cubic Meters, all BCM figures are annual figures) of water were withdrawn for use in the United States during 2015. This represents a 9 percent reduction of water use from 2010 when about 489 BCM were withdrawn and the lowest level since before 1970 (511 BCM).

In a recent article Ashwin B Pandya, Former, Chairman Central Water Commission (CWC) refuses to acknowledge either the adverse impacts of dams or the better option of using groundwater aquifer for storing water. And thus making unscientific arguments against dam decommissioning and for dams. No one is talking of removal ALL dams as the author seems to postulate and then dismiss it as impossible and irresponsible.
The Urban Water footprint in India is increasing in multiple ways. Rapid Urbanisation predicted by experts is just unfolding. Per Capita Demands are going up.
The City water managers are looking at big storages for dependable source of water, such big storages are necessarily far off from the cities. Cities are also generating sewage equal to 80% of the water they consume. Such storages created behind Big Dams have huge social, environmental impacts, besides massive economic costs and increased disaster risks. There is competition for water allocation from such sources, either existing, under construction or to be constructed. Such allocations for long distance cities thus creates conflicts, and potential disruption for cities, like the ones Delhi frequently faces, including in Summer of 2018.

The second wave of floods (first wave came in around May 20-24) this year inA North East India is affecting Tripura, Mizoram and mainly Barak Valley in Assam. Worryingly, while CWC flood forecast site shows water level reaching unprecedented levels in Manu river at Kailashahar in North Tripura District, CWC seems to have NO flood forecasting site in Mizoram. At Matizuri site in Hailakandi district in Barak Valley in Assam, the Katakhal river also approaching its highest ever flood level. In Bangladesh too sites like Amalshid have crossed the HFL.

Small rivers make big rivers. The health of big rivers depends on their smaller partners. But while bigger rivers are discussed, small rivers are normally absent in public discourse. They often lack govt or society’s attention.
Smaller rivers, typically tributaries of bigger rivers, are essential part of river eco-system. They hold the key to rejuvenation of big rivers. These small rivers are under multiple threats. They are slowly succumbing to damming, growing pollution, encroachments, mining and water extraction threats among others.
Kilkila is one such small river, with a fascinating story of its own.

The 225 m high Hindroituango Dam on Cauca River in Colombia continues to face emergency situation since April, and collapse of the dam is one of the likely possibilities. It’s a very large embankment dam being built Cauca River near to Ituango in Antioquia Province in Latima American country Colombia. The dam, estimated to cost $2.8 billion, was due to be completed this year. When operational it will generate 17% of the electricity demand of Colombia, but critics have been questioning the need for the dam. As we see through the details below, it is clear that the mega dam has been taken up without adequate geological, social and environmental studies, and now there is a big question mark if it will be successfully completed. There is a lot for the world to learn, here, including for Indian and South Asian Dam supporters.
Ominously, William Gutiérrez, a fisherman and gold prospector, after escaping the floods due to the dam last month, with nothing but the clothes he was wearing, told Guardian as vultures circled overhead: “We’ve always said this river could not be dammed. But the dam is more important to those in power than our lives.” Continue reading “Risk of collapse of Hidroituango Dam hangs over Colombia”→
Aquifers in 16 States in the country are contaminated by uranium, whose presence in drinking water has been linked to chronic kidney disease by several studies, a recent study has shown. More importantly, uranium doesn’t figure on the list of contaminants monitored under the Bureau of Indian Standards’ drinking water specifications. The main source of this contamination is natural, but groundwater depletion by extensive withdrawal of water for irrigation and nitrite pollution due to the excessive use of nitrogenous fertilisers may be exacerbating the problem, said the study.
– The study was carried out by a team of researchers led by Avner Vengosh, professor of geochemistry and water quality at the Nicholas School of the Environment at Duke University in the US. The team, which also included experts from the Central Ground Water Board, the Rajasthan government’s Ground Water Department and Gujarat Water Resources Development Corporation, analysed groundwater samples from 226 locations in Rajasthan and 98 in Gujarat.
