DRP NB 2 Dec. 2019: SC says Municipal Commissioners to be prosecuted under WP Law

In a number of ways the Supreme Court order this week that the municipal commissioners and chief officers can be prosecuted for releasing untreated pollutants from the cities to the rivers and other water bodies is path breaking. Can it help fix accountability of release of such untreated sewage? Can it help ensure that cities stop doing this and cities not only have adequate sewage treatment facilities, but also that cities have to ensure that the STPs function to ensure that no untreated sewage ends up the rivers and other water bodies?

Tivare Dam Disaster: Surviving in the State with maximum dams

Late that night of July 2, shouts of “Dharan Futla, Dharan Futla” (The dam has breached!) saved the already-scared 62 year old Narayan Gaikwad and his family, as the family ran to nearby hill[i]. Tivare Dam (Longitude: 73° 42′ 0″; Latitude: 17° 36′ 0″ as per CWC’s National Register of Large Dams), across a rivulet in the Vashishthi Basin of coastal Maharashtra breached around 9.30 pm on July 2, 2019, taking 24 men, women and children with its fury.

But how many and how much of Maharashtra would be saved considering the fact that Maharashtra has India’s highest number of large dams, BY FAR? And especially considering the serious questions this episode is raising about the absolute lack of accountability of the government dam establishment.

These questions become pertinent for Konkan region of Maharashtra, where Tivare was located as this region faces highest rainfalls in the state, steepest slopes and is tainted with several incomplete, illegal, inefficient dams which are posing a risk to humans and environment. SANDRP had published a report on incomplete and illegal dams in Konkan region 3 years back[ii]. High Court, SIT Committee Report headed by Madhavrao Chitale and even CAG [iii]had singled out dams in Konkan for their inefficiency and violations at multiple levels. The situation remains the same till date. Experts and past dam bureaucrats put on record that conventional dams-and-canals approach does not work in the steep and hilly region of Konkan. Quality assurance of dams is nearly nonexistent, lighter soils are used in dam cores and even after doing all this, displacing thousands of people and submerging Western Ghats forests, “Area irrigated by Konkan dams may be less than the area submerged by them”[iv] Continue reading “Tivare Dam Disaster: Surviving in the State with maximum dams”

Drought

Can floods lead to drought? After the flood, severe drought looming over Kerala

Guest blog by: Madhusoodhanan C.G. and Sreeja K.G

The state of Kerala experienced extreme precipitation events during the 2018 South West monsoon period with multiple episodes culminating in devastating floods across the state during 14th-18th August 2018. This year, with an early onset of monsoons that dovetailed with strong summer showers, the state received about 41% excess rainfall (2394 mm against the normal of 1700 mm) during the period June 1st to August 22nd [1]. Almost all of its reservoirs were near full storage by mid-July.

The heavy downpour and the uncontrolled opening of the spillway gates of almost all reservoirs that inundated huge stretches of river banks and floodplains, along with massive landslides across the Western Ghats affected more than 1.5 million people, with close to 500 human casualties, immense losses to property, livelihoods and resource security apart from the extensive damage to forests, wildlife and biodiversity. Maximum destruction was observed along the rivers of Periyar, Chalakudy and Pamba, all having multiple dams on their tributaries. The debate is still on as to the various reasons, both manmade and natural, behind the floods and the resultant wide-ranging casualties [2,3,4,5,6]. Meanwhile things have taken a rather unexpected turn in the flood ravaged state.

DRP News Bulletin 12 November 2018: Waterways Deteriorate Ganga, But Gadkari And Modi are Oblivious

PM Modi inaugurated the first multi-modal terminal on the Ganga river in Varanasi on Nov. 12 under a project aimed at promoting inland waterways as a cheaper and more environment-friendly means of transport. The multi-modal terminals are being built as part of the central government’s Jal Marg Vikas Project that aims to develop the stretch of the river Ganga between Varanasi and Haldia for navigation of large vessels weighing up to 1,500-2,000 tonnes. https://www.ndtv.com/india-news/pm-modi-to-inaugurate-1st-multi-modal-terminal-on-ganga-river-in-varanasi-1944924  (9 Nov. 2018)

Explaining the negative impact of waterways projects on Ganga River, Shripad Dharmadhikary in Hindi report titled जलमार्ग परियोजना बदहाल नदियों पर एक हमला writes that the projects lack public consultation “गंभीर बात है कि जलमार्ग विकास से सबसे ज्यादा प्रभावित होने की सम्भावना स्थानीय जनता को है। इसके बावजूद जलमार्ग के विकास से संबंधित ज्यादातर कामों के आयोजन और क्रियान्वयन के लिए न तो इनकी सलाह ली गई है, और न ही इनके बारे में जनता को जानकारी दी गई है। कुल मिलाकर इन जलमार्गों के सामाजिक और पर्यावरणीय प्रभावों का ठीक से आकलन नहीं हुआ है, ऊपर से इन्हें पर्यावरणीय मंजूरी के दायरे से बाहर रखा गया है और सारी प्रक्रिया में लोगों की सहभागिता का भी पूरा अभाव है। ऐसे में जलमार्गों के रूप में इतना बड़ा हस्तक्षेप हमारी नदियों पर एक और बड़ा हमला है जो पहले से बुरी हालत में हैं। https://www.downtoearth.org.in/hindistory/%E0%A4%A8%E0%A4%A6%E0%A5%80%E0%A4%B9%E0%A4%82%E0%A4%A4%E0%A4%BE-%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%AF%E0%A4%BE%E0%A4%B8-62034  (5 Nov. 2018)

Role of dams in Kerala’s 2018 floods

ABSTRACT: Many independent observers have argued that dams have played a role in increasing the proportions of Kerala flood disaster during July-Aug 2018. This article shows that Kerala dams violated many basic norms and if operated prudently, could have helped. It shows how post dam floods are different than pre dam floods. It lists the steps that would help in future disasters involving dams. The lessons are useful for all large dams of India.

In theory, every dam can help moderate floods in the downstream areas, as long as and as much as the dam has space to store water. In fact, every action that helps to store, hold, recharge (to groundwater aquifer), delay flow of rainwater from the catchment to the river would help moderate flow and hence flood in the river. Our catchments are fast losing that capacity, with continued destruction of natural forests, wetlands, local water bodies and also soil’s capacity to hold water.

DRP News Bulletin 1 October 2018: Hungry Water Effect due to Dams & Unsustainable Sand Mining Worsened Kerala Floods

Dams and reservoirs make rivers sediment-starved and menacing manifold downstream. While heavy rainfall is also a key factor behind the floods, hungry water had a more pronounced effect, says D. Padmalal, Scientist and Head, Hydrological process group, National Centre for Earth Science Studies.

– “When the sediment transport is interrupted, the potential energy of the hungry water released from dams will scour the river banks downstream, uprooting trees or riparian vegetation and damaging bridges and other engineering structures,” explains Dr. Padmalal. Overloaded with silt and clay from the eroding river banks, the highly turbid and viscous water clogs drainage channels. Subsequent discharge of water from the dam will lead to inundation and waterlogging of large areas.

– Hungry water can also develop in high gradient river channels devoid of adequate quantity of sand and gravel, especially during periods of high rainfall. “Years of uncontrolled sand mining have left most of the rivers in Kerala depleted or exhausted of sand and gravel. This creates a situation similar to the release of hungry water from dams,” notes Dr. Padmalal. When the river channel has adequate supply of sand and gravel, the potential energy of the water is used to transport the mixture. The water does not scour the banks or turn muddy.

South India Rivers Review 2017: More Water for Cities from Drying Rivers

This fourth rivers review presents developments related to rivers in States of South India including Telangana, Andhra Pradesh, Karnataka. 

Telangana Rivers 2017

Manair River Garbage polluting Manair river The shores are being polluted by the Municipal Corp of Karimnagar (MCK), which is dumping garbage generated from the town. Other private agencies such as chicken centres, hotels, private hospitals, mechanical shops and others too are also dumping garbage generated at their places into the river Manair. The State Govt had decided to develop the Manair front on the lines of Sabarmati river front development, which would spell further disaster for the river.  http://www.thehindu.com/news/national/telangana/Garbage-polluting-Manair-river/article17113713.ece (The Hindu, 30 Jan. 2017)

Remembering Latha

It took some time to write. Latha chechi and me talked just 4 days before she passed away on Nov 16, 2017. As usual, it was about when we will meet next and go to Athirappilly Falls and travel to the river together. Her voice was light, it had a surreal gentleness. We agreed on everything, which was rare. After just a few minutes, Unni gently took the phone from her and told me she needed to sleep. It just didn’t feel right.

We first met virtually about 10 years back, discussing rivers and forests and then, through her initiative, came together to organize the first civil society workshop on Environmental Flows in January 2009 with SANDRP.  Since then, Latha Chechi has been a bubbling, enthusiastic and wise constant. We worked on several submissions together, discussed strategies and ideas, eating each other’s heads about what worked and what can work and always, I was always taken aback by her unmatched way of linking issues.

She told me, “You need one particular river. Work on all the rivers of world, but have that one river to go back to.” Continue reading “Remembering Latha”
