A number of reports listed below this week throw fresh light on functioning of global water cycle, some of the findings should be seriously worrying. The studies show how the countries across the globe have water connections that go far beyond shared rivers, lakes and seas. And how these components of global water cycles are not only changing, but are under unprecedented stress and could take the global water cycles off balance.

Another study about atmospheric rivers that provides some of the largest high intensity rainfalls show that these rivers are shifting, which can have far reaching consequences for large sub-tropical areas, polar areas and others. For understanding their implications, more studies particularly focusing on shifting El Nino and La Nina streams are required.

DRP NB 170423:Forecast of Indian SW Monsoon & definition of normal monsoon

April 17, 2023 SANDRPLeave a comment

The India Meteorological Department (IMD) has on April 11, 2023 forecast that rainfall at national level in four months of June-Sept 2023 Southwest Monsoon will be 96% of Long Period Average (LPA). IMD considers Indian Monsoon rainfall as normal based on just one parameter of total rainfall in these four months at national level is between 96% and 104% of LPA, with model error of +/- 5%. This raises large number of questions as media has rightly raised post the IMD announcement.

Firstly, in a strange turn of events, on April 12, an update jointly by US weather agencies under the National Oceanic & Atmospheric Administration (NOAA), contradicted a number of assumptions of IMD the previous day, including the period when El Nino will become active and probability of it being a strong event, both of which have a strong bearing on the Indian Monsoon in an adverse way. So the first question that arises is, did the IMD not have the benefit of the observations on April 11 based on which NOAA made the forecast very next day? Or was it an attempt at providing an unjustified feel good monsoon forecast? This question arises as in the past too questions have been raised about such attempts by IMD. This question also becomes important as only a day or two before IMD’s forecast, private forecaster had predicted that monsoon rainfall is likely to be deficient and not normal.

DRP NB 060223: Wetlands in India face damages, threats and Govt Apathy

February 6, 2023February 6, 2023 SANDRPLeave a comment

(Feature Image:-Nayapakkam a lake near Chennai and a bird hotspot. 190 species have been recorded here and is a refuge for migratory harriers. https://ebird.org/hotspot/L3396760 Excavators were filling one end of the lake yesterday. Allegedly the ACS group is building an International school over it. M Yuvan, 05 Feb. 2023)

On the occasion of World Wetlands Day 2023 on Feb 2, 2023, SANDRP brought out five overviews about state of India’s wetlands. These included overview related to: 1. India’s Ramsar Wetlands 2. General overview of India’s wetlands 3. Top Ten stories about govt actions about wetlands 4. Top ten stories about judiciary actions about wetlands and 5. Positive stories about India’s wetlands. The links to the five overviews are available below.

The first thing that strikes from these overviews is that state of wetlands in India is bad, getting worse, they continue to face systemic neglect, damages, threats and govt apathy including Ramsar wetlands, which are supposed to have better protection than other wetlands, which is unfortunately not true. The nameplate of Ramsar wetland has now been given to 75 wetlands, but that provides no additional protection to them. in the name of information of Ramsar sites, there is only a combined interactive map apart from two separate pdf file links with location map and state wise listing Ramsar wetlands on Wetlands of India portal by MoEF&CC. The govt has neither prepared any concrete plan to address the threats nor has it developed credible monitoring mechanism which clearly shows it has no intention to improve the governance of these sites.

DRP NB 2 March 2020: Will Mumbai rise up against unwanted, destructive Gargai Dam?

March 2, 2020March 2, 2020 SANDRPLeave a comment

Mumbai Metropolitan Region (MMR), with annual rainfall in access of 2000 mm, does not do much to harvest the rain. It does not protect its local water bodies. It does not recharge groundwater to the extent it can easily do. It does not reduce its transmission and distribution losses. It does not treat its sewage to recycle and thus reduce freshwater demand. It does no demand side management. And yet it keeps demanding more water, and for that building of more dams and thus pushing more destruction. Without any credible options assessment. It has no water policy or water vision for smart water management.

The proposed Gargain Dam that will lead to destruction of over four lakh trees in 720 ha forest mostly in Tansa Wildlife Sanctuary, is a good example of how Mumbai is fuelling such dam building and destruction. The Rs 3105 Cr project will have many other impacts, including displacement of tribals and destruction of livelihoods for thousands others. As SANDRP report showed six years ago, (https://sandrp.in/2013/12/20/dams-in-tribal-areas-of-western-ghats-for-water-supply-to-mumbai-why-are-they-unjustified/, https://sandrp.in/2013/12/18/multiple-dams-for-mumbai-region/) and as our letter to the then Maharashtra Chief Minister emphasised in 2015 (https://sandrp.in/2015/01/13/water-smart-mumbai-open-letter-to-cm-devendra-fadnavis/), MMR region does not need any of these dams.

It was good to see MID DAY news paper report and EDIT highlighting some of these issues. Will the people of Mumbai Rise up, to stop this destructive dam, being pushed in their names, the way they stood up to save the far fewer Aarey Milk Colony trees?

DRP News Bulletin 11 March 2019: New Subsidies won’t Help Unviable Big Hydro; Timing Shows Big Dams Pushed for Political Economy

March 11, 2019April 1, 2019 SANDRPLeave a comment

The big hydro push that the Union cabinet passed on the eve of the National elections announcement surely won’t help the destructive and unviable big hydro projects. Big Hydro is already highly subsidised, with no credible assessment of its massive social and environmental impacts. These costs are borne by local people and not by the project developers. The cost of destruction of rivers and fisheries are not even assessed. The increased disaster impact potential due to the project is again not even assessed.

On top of it, the hydro projects are known to increase the flood disaster risks as seen in Kerala in Aug 2018 among so many other instances. So there no case for big hydro projects getting more subsidies. If at all there is case of reducing subsidies. But even these unjustified additional subsidies are NOT going to help push the big hydro, even private sector has realised that big hydro is unviable. Govt should not continue to push big hydro with public money, we hope the people will realise the foolishness and reject them. In changing climate, putting more money on big hydro is certainly not unadvisable. The timing of the move though only strengthens the argument that big dams are essentially pushed for political economy reasons rather than their merit.

According to a report, 2018 saw massive 16% drop in tourist visits to Himachal Pradesh compared to previous year, largely due to water crisis and increasing incidents of landslides, both factors due to environmental degradation, in which hydropower madness has played big role. It is worth to mention, that the Chief Minister of Arunachal Pradesh was first person to welcome Central government decision of incentivizing the hydro projects.

DRP News Bulletin 3 Sept 2018: CHINA HAS STARTED DECOMMISSIONING DAMS

September 3, 2018September 3, 2018 SANDRPLeave a comment

In a mountain village in southwest China’s Sichuan province, authorities have demolished seven small dam projects this year along a river to clear illegal developments in a new nature reserve. The demolition is part of a nationwide programme to close hundreds of tiny and often ramshackle dams and turbines and bring order to China’s massive hydropower sector after years of unconstrained construction.

The dams sat on an unnamed tributary of the fierce and flood-prone Dadu river, which feeds into the Yangtze, Asia’s largest and longest river, where the government says the “irregular development” of thousands of small hydropower projects has wrecked the ecology. But green groups say the campaign will not necessarily save the environment because it will not affect big state hydropower stations, which they say have caused the most damage.

On the 48 km Zhougong, authorities have already demolished small projects built in nature reserves or encroaching upon new “ecological red lines” drawn up to shield a quarter of China’s territory from development.

The government says small dams have disrupted the habitats and breeding patterns of many rare species of fish, although green groups argue the damage wrought by bigger dams is more severe, with entire towns and ecosystems submerged in water, which they say increases the risk of earthquakes, landslides and even climate change.

DRP News Bulletin 26 March 2018: Massive Farmer protest in Palghar against water diversion

March 26, 2018March 26, 2018 SANDRPLeave a comment

MASSIVE Farmer protest in PALGHAR (Maharashtra) The protest for the third day on World Water Day, was against diversion of water from Survya Dam for Vasai-Virar and Mira-Bhayander. under the aegis of the Surya Pani Bachav Samiti.

– The contract to construct the 88-km long pipeline has already been awarded to the L&T Group by the Mumbai Metropolitan Region Development Authority (MMRDA) under the Surya Regional Bulk Water Supply Scheme.

– Ramakant Patil, chief convenor of the SPBS who is also undertaking the fast, said the Surya dam, which was built in 1990 over the Kawdas and Dhamni rivers in Kasa taluka,Dahanu, was specifically for irrigational purpose for 19,000 odd acres of farmland in Palghar district. “Now the MMRDA is planning to divert around 89% of the dam water to the above cities so as to solve the cities’ drinking water issues, but we the farmers would be denied water for our land,”said Patil.

– They withdrew it after an assurance of a meeting with chief minister Devendra Fadnavis. “We have raised this issue for many times in the past. But it is for the first time that a CM has agreed to sit with us and discuss. Now we are just waiting to hear from the CM’s office to know the date of meeting,” Brian Lobo of Kashtakari Sangathan adds. https://www.hindustantimes.com/mumbai-news/palghar-farmers-fast-over-diverting-surya-dam-water-enters-third-day/story-LsTeF2vf6xuVroPRO2GSYJ.html, http://www.dnaindia.com/mumbai/report-urban-areas-rob-tribals-of-water-supply-2597713 Continue reading “DRP News Bulletin 26 March 2018: Massive Farmer protest in Palghar against water diversion” →
