DRP NB 260922: Need for new credible Polavaram backwater study

(Feature Image:- The construction of the Polavaram dam across the Godavari river has posed a big threat to the Pulasa fish, as its movement to the upstream of the river could be curtailed. HT PHOTO).

Telangana state has demanded fresh backwater study for the Polavaram dam based on a number of grounds including the higher spillway capacity and outdated river cross sections of 1990s used in the old study. The changing rainfall pattern and resultant changing river flow pattern, both due to changed rainfall and changed state of catchment area also should be a reason for such a fresh study. However, more importantly, the study needs to be done in a credible way involving independent experts, not just state or central govt officials or academics from govt run institutions. Moreover, the study and all the information related to it has to be completely and promptly in public domain as these studies are required for the affected people and affected area. Normally Central Water Commission does such studies and refuses to make it public. What is the use or reason for backwater study to be secret? Possibly CWC is not confident of the quality of the study and that is why it is very important to have experts in the study team who are known to take independent stand. It is useful not only for the states of Telangana, Odisha and Chhattisgarh, but also for the people of Andhra Pradesh too. And earlier this is done, better it will be for all concerned.

DRP NB 120922: Decisive judicial action dire necessity for wetlands

( Feature Image:- Satish Acharya’s illustration on Bengaluru floods: Whose land is it anyway? 07 Sept. 2022)

The wetlands reports tell us a lot, but the key point is that decisive judicial action is necessary if our wetlands are to have any future. The directions of the Tamil Nadu High Court to geo reference all wetlands of Tamil Nadu, including small (Less than 2.25 ha area) is good beginning, but the court will need to ensure continuous monitoring and ensure implementation. Because the past shows that the government and other stakeholders have collectively failed to take any decisive action to save our wetlands. The disastrous results are evident at so many places, this week it is most clear from the flooding of Bangalore, mainly due to encroachment of lakes, wetlands, water channels and their catchments.

DRP NB 110722: Govt failure on cloudburst monitoring, forecasting, managing

(Feature Image: On July 8, a flash flood triggered by a cloudburst hit a camp near the Amarnath cave shrine in J&K’s Ganderbal district. The Indian Express)

Just in first few weeks of this South West Monsoon in India and particularly in last two weeks there have been numerous cloudburst incidents leading to large number of deaths and destruction of human and natural infrastructure. Most of the time, the government just calls these disasters cloud burst and points finger at climate change, implying its helplessness, but happy that they have rescued the affected people. In reality, a lot can be done in terms of monitoring, forecasting and managing cloudbursts that is clearly not happening and is not part of government’s disaster management plans or actions.

Firstly there are some known places where the flash floods from cloud burst could lead to disaster, they need to be identified and habitations near and at risk at such locations need to be mapped and monitored to minimize the risks. The locations next to streams are clearly such hazardous locations and how can there be camps located right next to such streams as happened during the recent Amarnath caves?

Kerala and Uttarakhand floods in Oct 2021: Did the forewarnings help?

The October 2021 flood disasters in two ends of India, in Kerala and Uttarakhand have a lot common. Both happened after the end of normal dates of South West Monsoon 2021. In both cases it is repeat of earlier such disasters in respective states. In both cases, there were reports by expert reports warning about the disasters. In both cases the rainfall events were broadly along the lines warned by the climate scientists, but in both cases the state was ill prepared to cope with it. In both cases, inappropriate human interventions have worsened the disasters in major ways. And in both cases disaster management seems to be absent from ground. In both cases, more precise forecasts about the rainfall quantum and location would have helped. (Feature Image above is from The Hindustan Times, Oct 23, 2021)

DRP News Bulletin 11 Oct 2021: Are we being forced towards nature based solutions?

Four interesting developments in this week seems to suggest that mankind is being pushed closer to nature based solutions to society’s needs. In Brussels in Belgium (Europe), the local government has started to uncover the Senne river that now is hidden under the pavements with the declared objective to “return nature to the city” and the river becoming an ecological corridor in the city.

In USA, the Army Corps of Engineers, more known as Dam builders, have over the last five years, moved towards nature based flood control by creating wetlands. In the 2020 Water Resources Development Act, US Congress directed the Corps to consider nature-based systems on equal footing with more traditional infrastructure. Its possibly a baby step, but a very significant one for a traditional dam building organisation that has stopped building dams and have been working towards decommissioning dams.

Uttarakhand 2021: Cloud Bursts around Vyasi HEP

On August 25-27, 2021 the most of hilly districts in Uttarakhand witnessed intense rainfall events causing widespread destruction. Media reports and local people suggest at least seven cloud burst incidents occurring in quick succession over Binhar range in Pacchawadoon and Mussoorie hills dividing Ganga and Yamuna basins in Dehradun district. The resultant deluge has also affected the under construction Vyasi Hydro Electric Project (HEP) areas in Vikas Nagar tehsil highlighting that the project is unprepared to cope with existing & emerging disasters.

Why are Patna & Bhagalpur facing unprecedented floods on India’s 75th independence day?

As India prepares to celebrate 75th Independence day on August 15, 2021, large parts of Bihar along the Ganga river, including Patna (flood water entered colonies near Ganga in Patna) and Bhagalpur are preparing to face unprecedented floods. In fact, Central Water Commission’s (CWC) flood monitoring site at Hathidah in Patna district crossed the HIGHEST FLOOD LEVEL (HFL) of 43.17 m at 0300 hours in early morning on Aug 13, 2021. The water level is already at 43.33 m at 1300 hrs on Aug 14. It is forecast to reach 43.45 m by 0800 on independence day still with rising trend. This is apparent from the CWC hydrograph of this site shown above.

DRP NB 28 June 2021: Where is the impact of lessons of the water conservation efforts that Modi praises, on his government’s water projects and policies?

When the Prime Minister Shri Narendra Modi Mentioned some exemplary water conservation efforts in his Mann ki Baat on June 27, 2021, it was not for the first time he was doing it. These are certainly most welcome.

However, these mentions raise a number of questions. If the Prime Minister considers these local water options as exemplary, which they indeed are, where do we see the reflection of the lessons from such efforts in government programs and policies? In fact why there is no reflection of such lessons in what the government does in water sector? How can the government justify the destruction of Panna Tiger Reserve, over 9000 ha of forests, some 46 lakh trees, the catchment of Ken river and large part of Bundelkhand in the name of Ken Betwa Link Project, in the same Bundelkhand. How can his government justify the destructive projects like the Char Dham Highway, the big hydro projects and so on in the same Uttarakhand where Sachidanand Bharati (who was incidentally recipient of the Bhagirath Prayas Samman of India Rivers Week) works, whose efforts the PM praised? One hope the PM and his government will be awake to the implications and lessons of the works that PM praises.

Uttarakhand: Cloud bursts in May 2021

From the beginning of May 2021, Uttarakhand has started witnessing excessive rainfall events termed as ‘cloud bursts’. Worryingly the intensity and frequency seems on higher side this time. So far there have been about 24 reported cases of ‘cloud bursts’ in the state but the monitoring, prediction and mitigation efforts are lagging far behind.

DRP News Bulletin 1 March 2021: Actions speak louder than words on PM’s appeal for water, river conservation

In his #MannKiBaat on Feb 28, 2021, India’s Prime Minister Shri Narendra Modi appealed to people to conserve our Rivers, Water, referring to Magh Purnima on Feb 27 2021 and Sant Ravi Das teachings. He also said that India’s traditions, festivals, scriptures, etc have so much place for rivers, also mentioning the Kumbh mela this year at Haridwar. He mentioned that a 100 day campaign will be launched soon by the Jal Shakti Ministry for rainwater harvesting. He gave several examples from across the country where individuals and groups have taken up such words.

All that sounds fine and welcome. But the trouble is that his all-powerful government is working consistently and with increasing intensity towards opposite direction. This very week his Power Minister expressed ignorance if hydropower projects have any environmental adverse impact, right in the face of destruction wrought by the hydropower projects in Chamoli disaster in Uttarakhand on Feb 7, 2021. Why is the Union Government still pushing hydropower projects which are no longer even economically viable, they never were environmentally sustainable or socially acceptable.
