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.
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.
How is development possible along with environment protection? There are two kinds of answers possible to this question. The standard kind of reply would try to provide a list of options that are available to a given development need.

HIMACHAL PRADESH Water scarcity leaves Shimla high and dry Residents in the city are reeling under acute water shortage for the last few days. They are getting rationed water supply after four-five days.“Hoteliers are paying private tankers Rs 2,600 for 6,000 litre water,” said Harnan Kukreja, president, Shimla Hoteliers’ Association. The Shimla Municipal Corporation is struggling to ration 21 MLD of water that was pumped from its major sources these days. The water availability per resident was just 5 litre as on May 25.
The city needs 45 MLD water daily, but the water availability has come down from 29 MLD last week to 21 MLD on May 25, 2018. Guma, which has 20 MLD capacity, and Giri, which has 20 MLD capacity, could supply just 4 MLD and 14 MLD, respectively, revealed MC supply chart. Churat supplied 1.25 MLD, Chair (0.32 MLD) and Koti- Brandi (0.35 MLD).
Around 4-5 MLD water is getting wasted due to leakages in supply lines before it reaches MC storage tanks in the city. The state government and the MC have failed to compensate for the water that it used to get from the Ashwani khud, supply from where was suspended in 2015 following a jaundice outbreak in the city. http://www.tribuneindia.com/news/himachal/water-scarcity-leaves-shimla-high-and-dry/594998.html (The Tribune, 26 May 2018) Continue reading “India’s Summer of Water Crisis in 2018”
On occasion of International Day for Biodiversity May 22, 2018, the Union Minister for Water Resources, River Development and Ganga Rejuvenation Nitin Gadkari released the report on “Status of Conservation of Select Aquatic Species” in river Ganga in New Delhi . The celebrations have been organised to mark the 25 years of coming into force of the Convention on Biological Diversity. He also inaugurated a day-long workshop organized by World Wildlife Fund (WWF) on the theme “Ganga and its Biodiversity: Developing a Road Map for Habitat and Species Conservation”.
A database of Ganga Praharis’, a self-motivated cadre, being created by Wildlife Institute of India (WII) was also launched by the Minister. Shri U.P. Singh, Secretary, Ministry of Water Resources, River Development and Ganga Rejuvenation said: “Ganga still has about 2,000 aquatic species.” He also pointed out that both aviralta and nirmalta of river Ganga are important and the government is committed to achieve both.
According to an energy expert, 6,000 megawatts’ worth of wind and solar contracts had been signed in Cambodia, Vietnam, Thailand and Laos in the last six months, seriously challenging the financial viability of major hydropower projects on the river. Buoyed by a recent Thai government decision to delay a power purchase deal with a major mainstream Mekong dam, clean-energy proponents and economists told the third Mekong River Commission summit that the regional energy market was on the cusp of a technological revolution.
A six-year Mekong River Commission Council study on development plans for the Mekong, which was the focus of the summit, suggested catastrophic impacts upon the health of the river system if all planned hydropower dams — 11 mainstream projects and more than 100 on tributaries — were built.
SOUTH EAST ASIA Rivers are invaluable INTERESTING QUESTION: HOW MANY DIFFERENT WAYS CAN YOU MEASURE A RIVER? “Perhaps the most important – and largely overlooked – measure of a river is its value to the economy and wellbeing of a nation, a region, and its people. Simply put, large healthy, productive rivers like the Mekong and Ayeyarwady (or Irrawaddy) are unifying geographic features that serve as economic juggernauts, essential to long term growth and in maintaining the quality of life for millions of people.”
“These (FLOOD) benefits are valued annually at US$8-10 billion (K10.8 trillion), while floods in the Lower Mekong basin cause a much lower $60-70 million in damage every year.” “Floods and sediment are the artisans of river systems. If you lose them you are left to human-engineered solutions. That is now the only option for the US government in the Mississippi River. A $50-billion program has just been launched to rehabilitate the Mississippi delta. Conserving the natural processes that created it in the first place would have been a much more cost efficient option.” https://www.mmtimes.com/news/rivers-are-invaluable-south-east-asia.html Continue reading “ASIA-2017: Surplus power, cancelled Hydro and dam risks dominate”
FRANCE Largest dam removal project of the continent launched With thousands of proposed dams threatening Europe’s few remaining free flowing rivers, France’s decision to remove two large dams could signal the start of a new era on the continent – with countries focusing on reviving their rivers and on large scale dam decommissioning rather than construction.
With France leading the way, countries from Spain to Finland have taken down many small and obsolete dams in recent years, but freeing up the Selune represents the largest dam removal project so far in Europe – and a major step towards bringing life back to the river, including wild salmon and eel whose migrations have been blocked by the dams for decades. http://www.eubusiness.com/focus/17-11-212 Continue reading “EUROPE-2017: Dam Removal, Hydro Threats & Cancellations, River Restoration in focus”

DECOMMISSIONING OF DAMS
Map of dams removed since 1916 Dams cause considerable harm to rivers. Dams have depleted fisheries, degraded river ecosystems, and altered recreational opportunities on nearly all of our rivers. Today, many dams that were once at the epicenter of a community’s livelihood are now old, unsafe or no longer serving their intended purposes. Learn how USA is working to remove dams and restore the rivers. (Map above is from Ameerican Rivers website, depicting the location of decommissioned dams in USA.) https://www.americanrivers.org/threats-solutions/restoring-damaged-rivers/dam-removal-map/ Continue reading “US Dams, Rivers and People in 2017: There is so much to learn!”
