The annual Conference of Parties (COP) on climate change begins its annual meeting in Brazil today. Consider the track record of the annual meetings so far, it is a valid question to ask, as the Question of Cities asks, Does the World still need this meeting with such a huge carbon footprint of its own? Is it a futile exercise now?

Some of the most prominent reports this week are related to wide spread opposition to large hydro projects in Arunachal Pradesh, Himachal Pradesh, Kerala, among other states. Indeed, there is little sense in building large hydro projects as strategic assets as seems to be the case in Himachal Pradesh and J&K (Chenab basin) and Arunachal Pradesh (Siang basin, among others). Use of security forces to complete pre-feasibility survey when local communities are strongly against the project, as is being done in case of Siang Upper Multipurpose Project is clearly counter-productive in so many ways. In Kerala people have again gathered to oppose the destructive Athirapally Hydro projects that they have been successfully opposing since late 1990s.

One of the alarming news this week is the recommendation of irrigation experts and others to the Telangana govt is to prioritise Tummidihatti project, rather than spending limited available resources on repair of Kaleshwaram barrages: Medigadda, Annaram and Sundilla, all part of the controversial and disaster hit Kaleshwaram Project. The reasoning behind the recommendation seems to be apparent difficulty to rehabilitation of the barrages with inherent unstable foundation on sand beds.

One aspect that stands out not so obviously in the ongoing water dispute between Punjab and Haryana is the poor track record of BBMB in achieving operational safety of BBMB projects during floods, particularly in recent years, but also starting from way back in 1970s. That is why it sounds strange when in early May, BBMB is talking about need for water releases to safeguard the Bhakra dam’s structural integrity, when the dam is at its lowest level in the season. We see no such urgency or public statements by BBMB during the monsoons last few years when not only IMD had forecast heavy rainfall in the catchment, but also there was no action by BBMB even when catchments had already received heavy rainfall.

The visit of chairman of National Dam Safety Authority (NDSA) to Srisailam and Nagarjunsagar dams on Krishna River belonging to Andhra Pradesh and Telangana has brought out very worrying reports. These are two of the largest dams in India. This is symptomatic of the situation of dam safety across the country.
Srisailam dam was damaged during unprecedented floods in first week of Oct 2009 with washing away large amount of cement concrete from the apron and plunge-pool of the dam, but the repair work has still not been taken up even though there is risk to the stability of the dam. The discussion is still about source of funds and NDSA chairman has asked AP to initiate some work using AP’s own funds and get the expenses reimbursed afterwards. This is a hardly confidence inspiring situation. Any mishap on this project can start a chair reaction that can engulf all projects right upto Krishna barrage at Vijaywada.

The National Dam Safety Authority (NDSA) expert committee report under chairman Shri J Chandrashekhar Iyer on the controversial Kaleshwaram project has at long last been submitted this last week to the Telangana govt vide DO letter dated April 24, 2025, from Shri Anil Jain, NDSA chairman. One of the intriguing aspects of this episode is that the NDSA expert committee submitted the report to the Ministry of Jal Shakti in December 2024 and it has taken almost four months for the report to be submitted to the executing authority, the Telangana Govt. Why should it take any time at all for the NDSA expert committee report to reach the state government, leave aside the 4 months it has taken.

The 2304 m long Farakka dam on Ganga in Murshidabad district in W Bengal was commissioned on Apr 21 1975 and completes 50 years today. The dam needs an independent review to assess the costs, benefits and impacts of the dam, both projected and actual and to decide about the need and form of its continued existence.

The private forecasting agency Skymet has forecast Normal SW Monsoon rainfall across India on Apr 8, 2025, a week before IMD comes out with its forecast. This advance forecast by private agency, compared to IMD raises question as to how come the private agency with much more limited resources is able to achieve this.
In any case, the forecast of about 3% above normal rainfall in June Sept 2025 is welcome. The rainfall distribution forecast, both across the four months and across the four regions is also good if it comes true.

New research published this week reveals a startling change: the oxygen levels in inland waters has been dramatically reducing since 1900, due to human activities including big dams and pollution. This condition leads to dead fish, collapsing food chains and reducing water quality, among other impacts.
There are simultaneous processes ongoing in inland waters leading to production and consumption of oxygen. The location and processes for both the production and consumption of oxygen has been changing during 1900 to 2010. The Global oxygen consumption in inland waters, net of production has gone up by over 100% from 0.26 Pg/year in 1900 to 0.53 Pg/ year in 2010. While earlier climate change was considered major contributor to this reduction, new research shows it is big dams and pollution that are much bigger contributors. Inland waters now pull nearly 1 billion tons of oxygen from the atmosphere every year — half as much as the entire ocean emits back.
Continue reading “DRP NB 070425: New Impact of Big dams: Increased oxygen intake in inland waters”Maharashtra Chief Minister Devendra Fadnavis, brushing aside the concerns of forest officials, opposition, environment and available options this week has asked the officials to fast track the Forest and other clearances for the controversial Gargai dam for additional supply of water to Mumbai. This is shocking on several counts.
Our study earlier showed that Mumbai does not need any additional dam including Gargai if it utilizes available local resources including rainfall, reuse of treated sewage, desalinization, demand side management, groundwater recharge, among other cost effective and less destructive options. The Chief Minister of his government has not bothered to respond to these concerns or options. In fact, when our study was published, even government officials in Mumbai had supported our conclusions.
