In order to have high standards of dam safety the prerequisites are designing and constructing dams with reasonable safety margins; operating and maintaining them safely; and having emergency arrangements to address situations that might arise. Operation of dam within its ambit also includes thorough understanding of likely impacts and its management in case of flooding, in any emergency situation or in the event of dam failure, both upstream and downstream on communities living there, their livelihoods and also on infrastructure and property which can get affected. In fact in many countries like Sweden and in many states of the USA, a dam is assigned a dam safety class i.e. A, B or C depending upon the significance of the damage that might occur in case of dam failure, class A being assigned to dams whose failure might cause significance loss of public life and property. Dam safety requirements are calibrated accordingly and a higher burden is put on dam owners of higher class, concerning safety management system, emergency plans, overall assessments, and annual dam safety reporting.

DRP 091023: MoEF Panel concerned about impacts of Small Hydro
(Gangani SHP on Yamuna river in Uttarkashi affected by June 2013 flash flood. Image: Yamuna Jiye Abhiyan/July 2013)
The Forest Advisory Committee of Union Ministry of Environment and Forests (MoEF) have rightly raised concerns about the impacts of so called small hydropower projects, that is hydropower projects with capacity below 25 MW. The MoEF assumes, following such unknown science or logic, that such projects have no environment and social impacts, they do not need environment and social impact assessments or management plan, they do not need any public consultation process, they do not need any monitoring or compliance and most significantly, they do not even need any clearances! A more unscientific thinking of the govt of India’s top environmental body would be difficult to find.

DRP 021023: Why this culture of opaque governance around Joshimath?
(Feature Image: A temple collapses after the gradual ‘sinking’ of Joshimath in Chamoli district, on Jan. 08, 2023. PTI/HT)
It is clear that the Union and the Uttarakhand government did not want the reports prepared by different national institutes related to Joshimath Sinking, to be made public and the state High Court had to order it to do so. The government’s view of the report is clear from that. It took the judiciary so many months to finally order the report to be made public. What is it that the government wanted to hide? Why? From whom? Why is there this culture of opaque governance even in disaster management related issues? Is it growth fundamentalism that is driving the government as the single most factor? Or is it the arrogance and adamant attitude of the governance, not wanting to consider any questions raised against their decisions? Why is there so little faith in the people, society and transparent, accountable governance? Why is the judiciary allowing such a culture to prevail generally?
These are some of the key questions that arise from this and other such episodes.

DRP 250923: World Rivers vs Indian Rivers on Rivers Day 2023
(Feature Image: Najafgarh drain loaded with polluted water joining River Yamuna downstream Wazirabad barrage in National Capital in June 2023: SANDRP)
Sept 24 is celebrated as the World Rivers day since 2005, the tradition started by river advocate Mark Angelo, who used to celebrate BC (British Columbia in Canada) Rivers day since 1980. There is some good news for rivers across the world in terms of decommissioning of dams, improving environment flows, movements to clean rivers, improve fish migration, protection of flood plains, room for the river, decommissioning of channelisation projects, among others.

DRP 180923: Floodplain loss, the biggest in Asia, disaster in the making
(Feature Image: Ongoing ghat work along Yamuna at Qudsia ghat, ISBT Dellhi. SANDRP, June 2023)
A floodplain, according to the US Federal Emergency Management Agency, is “any land area susceptible to being inundated by floodwaters from any source”. According to the report “Human alterations of the global floodplains 1992–2019”, over 460,000 sqkms of floodplain area was lost to agriculture, while another 140,000 sqkms was redeveloped to new areas over the existing floodplain. Continent-wise, Asia lost the biggest area of floodplains — a little over 200,000 sqkms — among all the continents. It was followed by South America (92,000 sqkms) and Africa (73,000 sqkms).

In July and August 2023, two more hydro electric power (HEP) projects have faced cloud burst induced flash flood destruction in Himachal Pradesh. The first one is Kuther HEP in Chamba district and the second one is Pittkari HEP in Mandi district. The details of 2 HEPs (14 MW GreenKo HEP in Sutlej basin, Shimla and 66 MW Dhaulasiddh HEP in Beas basin, Hamirpur) earlier impacted by cloudbursts induced deluge in last week of June 2023 can be seen here.

DRP 110923: Another independent institution-CEC destroyed
(Feature Image: Ramganga River near Marchula. SANDRP 08 Sept. 2023)
The Govt of India’s Sept 5 2023 notification reconstituting the Central Empowered Committee completely destroys the independent nature of this institution of accountability and course correction. This institution, set up by the Supreme Court in 2002 and reconstituted in 2008, worked as eyes and ears of the Supreme Court on environmental issues. The new committee has no independent members, it will be constituted by the MoEF, MoEF itself has such an abysmally poor track record.
The notification, reports said, diluted the CEC’s autonomy on four key counts: the committee will report to the ministry, instead of the SC; the ministry will pick all the members and the SC will have no role in the process; the ministry, and not the court, will fund the committee; the provision of having two NGOs in the committee has been done away with.

Though August 2023 has turned out to be hottest and driest month in a century; the first half the month has seen extreme flood events happening in North, North East and Central zones of the country causing breach in the highest flood level (HFL) at least at 17 flood monitoring sites being managed by Central Water Commission (CWC). These sites are in Ganga, Narmada and Brahmaputra basins.
There are some sites where HFL has been breached in June and July 2023 also and peak flood level of these sites is given below the peak levels attained in August 2023. The details of 2 sites breaching HFLs in June 2023 & 38 sites in July 2023 can be seen by clicking on respective hyperlinks. A separate report analyzing the severe flood situation in Alaknanda and Ganga basin on August 14, 2023 can be seen here.

DRP 04092023: Will National Ganga Mission too fail to clean up Ganga?
(Feature Image: Untreated industrial effluents being dumped in Drain No. 6, Sonipat in May 2023.)
More than 7 years have passed since the central government launched Rs. 20, 000 crores Namami Gange Programme in May 2015 replacing Ganga Action Plan (GAP) and created National Mission for Clean Ganga (NMCG) a nodal agency to implement the programme.
The NMCG has already missed the target of cleaning the Ganga by 2019 and then by 2020 due to improper planning and Detailed Project Reports (DPRs) as accepted by G. Asok Kumar, Director General (DG), NMCG in an interview to The Week in January 2023 further extending the target to 2026.
Though Namami Gange aimed to adopt a basin wise approach with focus on e-flows, afforestation, revival of tributaries, biodiversity conservation in participatory manner; so far it has extensively worked on creation of sewage treatment infrastructures in the states along the main stem of the river.
Despite that the ground situation is far from improving as shown in the The Hindu report below which reveals that about 80 percent of the overall budget is being spent on sewage infrastructure creation and by 2026, the treatment plants capacity would be able to treat at the most 60 percent of sewage generated only along the main stem of the Ganga river.

DRP 280823: Defund nature destroying activities

This is indeed the key message if we are serious about tackling climate change with any sincerity. The adverse impacts of mindless activities in the name of development, are acting as force multipliers for climate change impacts as we are experiencing first hand, latest example being in Himachal Pradesh and Punjab.
Particularly when the “development” activities are done without credible project specific and cumulative impact assessment, genuine public consultation process and confidence inspiring monitoring and compliance processes, as is the norm.
