Mullaperiyar: Dam’ned’ & Divided | Mint

Alongside along with her household, Subina lives with the spectre of a water disaster. Her worries, nonetheless, aren’t about faucet water, however a big, ageing reservoir stuffed to capability. In the future it’ll burst and wash their lives away, she fears.

The village of Vandiperiyar is a couple of kilometres downstream of the Mullaperiyar dam in Idukki. As a wedding migrant, Subina picked up on these fears from her new household and neighbours, for whom discussing court-sanctioned water ranges within the dam, its carrying capability, seepages in its construction, its convoluted litigation and political implications is dinner-table dialog. Subina, who can also be learning for her civil service entrance exams, is so extremely good and articulate that she’s spoken up concerning the fears and calls for of the locals right here on Malayalam TV information debates.

“The water right here in our properties shouldn’t be potable, however we’re not anxious about that,” Subina advised Mint. “We don’t need any of the water from the Mullaperiyar to be given to Kerala. We simply need to have the ability to stay right here safely and for that, the one resolution is to construct a brand new dam.”

A long time in dispute

Kerala, the place the dam is positioned, and Tamil Nadu, which controls the circulate of the water contained in the reservoir, have been locked in a decades-long bitter dispute concerning the security of the 126-year-old construction.

Native politicians on each side maintain feelings operating excessive and construct resentment, often permitting it to boil over into protests and riots, regardless of pretty shut social and financial relations between the border districts. Idukki hosts a considerable inhabitants of Tamil-speaking settlers who labour in its tea and spice plantations whereas Malayalis typically cross over into Tamil Nadu for work and better schooling.

Kerala is satisfied the dam presents a risk—if it bursts—to not simply the inhabitants instantly downstream however {that a} domino impact on neighbouring reservoirs would wipe out tens of millions of lives in districts so far as Kottayam, Ernakulam and Alappuzha. Throughout state traces in Tamil Nadu, within the rain shadow of the Western Ghats, the water from the Periyar river routed via this dam has been an irrigation lifeline to just about three lakh hectares of drought-prone agricultural land for over a century that they refuse to gamble with.

This dispute on dam security, which Tamil Nadu claims is a fallacy, has been argued at each state excessive courts and the supreme court docket for 20 years now. Whereas the 2 state governments proceed to face-off on this political brinkmanship, native residents, these reliant on the dam for his or her livelihoods in addition to those that concern for his or her lives, proceed to be cautious of one another.

Central Kerala districts have confronted successive flash floods, with in depth lack of life and injury to property, from the 2018 to 2021 monsoon seasons. Whereas adjustments in long-term local weather patterns have made adversarial climate occasions extra frequent, residents downstream the Mullaperiyar dam are livid with Tamil Nadu for what they expertise as a sudden discharge of water from the dam with no early warnings. That worsens the monsoon floods. The fears of a dam-related disaster have reached a crescendo in Kerala but once more and the state authorities has, as soon as extra, demanded a security evaluation on the supreme court docket.

Who advantages?

James Wilson is a dam security skilled and member of a particular advisory group of the Kerala State Electrical energy Board which owns and operates massive hydel tasks within the state. Wilson was a part of Kerala’s second litigation on the dam, that led to the supreme court docket appointing a supervisory committee in 2014 to repeatedly monitor the dam’s resilience.

On the coronary heart of the disagreement is the disproportionate profit to Tamil Nadu from the dam, and the state’s refusal to acknowledge the protection perceptions of these residing downstream, Wilson stated. “Tamil Nadu generates electrical energy from the dam in addition to all of the water whereas Kerala bears all the danger. So, a sustainable resolution is for a brand new dam to be constructed with funding from each states and each sharing the electrical energy the hydel plant generates. Till then, this debate received’t be resolved,” he stated.

“The committee, with representatives from the 2 state governments and a senior officer from the Central Water Fee (CWC), solely visits the dam twice a 12 months,” Wilson added. “As an alternative, what we want is steady monitoring of each the water ranges and the structural energy of the dam. Security is a dynamic perform right here. Ideally, we should always create a joint knowledge assortment and publication methodology that’s clear and can create confidence among the many residents downstream that the dam is protected.”

“Purchase lifeboats”

The refrain to decommission the dam peaked final 12 months, when a petition by a Kerala Excessive Court docket advocate Russel Pleasure racked up 840,000 on-line signatures, together with from a few of Malayalam cinema’s greatest celebrities.

Understandably, Pleasure is a vocal opponent to the dam’s continued functioning, a view he airs steadily as a visitor at political occasions and on TV interviews. In 2018, he efficiently petitioned the supreme court docket to arrange a catastrophe administration panel for the dam. In a current video for a Malayalam information channel, Pleasure speaks to his viewers from a stationary speedboat, presumably from someplace alongside the state’s famed backwaters. Pleasure opens his 10-minute handle explaining why he’s within the boat.

“The proprietor of this boat isn’t right here with me at this time, however I can let you know that he purchased this in case the Mullaperiyar dam breaks; the boat will let him escape into open sea rapidly,” Pleasure says in Malayalam. “This has turn out to be our final resort now, hasn’t it?”

Pleasure advises his viewers who can afford speedboats to purchase them quickly, and lifejackets, for everyone else. “Earthquakes have gotten extra frequent in Kerala and who is aware of what number of dams right here will break,” Pleasure continues. “What we do know is that our governments aren’t prioritising our security. So, purchase a life raft. It prices 35,000-40,000 and (when the dams break) it can save you six-seven folks this fashion.”

Pleasure has a writ petition pending earlier than the supreme court docket asking it to nominate a global company that may choose the remaining lifespan of the dam and repair a date for its decommission. His major argument is that dams have a median lifespan of about 40 years and are sometimes decommissioned in different international locations after this era. A 126-year-old dam, then, has no hope of constant to perform.

Conflicting positions

He’s not essentially appropriate. Mullaperiyar, actually, shouldn’t be the one dam that’s over 100 years previous in India. Within the CWC’s nationwide register of enormous dams, there are a number of others which might be over a century previous and nonetheless operational.

“Based mostly on our critiques, we have now typically really helpful stability strengthening measures for the dam to be carried out by the Tamil Nadu authorities,” a senior CWC official, who requested anonymity since he’s not authorised to talk to the media, advised Mint. “A few of these suggestions have been pending since 2006 as a result of even when Tamil Nadu agrees to hold out this work, the Kerala authorities denies them permission to take action on the bottom.”

Somewhat counter-intuitively to its public stance on prioritising security, Kerala has steadily thwarted efforts by Tamil Nadu to hold out strengthening work on the dam. As an illustration, final November, it denied permission to Tamil Nadu to chop bushes downstream of the child dam to strengthen it. (The infant dam is among the 4 dam constructions, which additionally features a major dam, earthen dam and spillway). Kerala believes any strengthening work on the dam will weaken its personal demand for a brand new dam; Tamil Nadu hopes that finishing the protection suggestions will enable it to argue in favour of elevating the really helpful reservoir degree to its most capability.

Altering local weather patterns

Roxy Koll, a senior local weather scientist, has studied how monsoon patterns in India have modified for the reason that 1900s. His workforce on the Indian Institute of Tropical Meteorology, Pune, discovered that whereas whole annual rainfall from the south west monsoon has lowered total for the reason that Fifties, quick intervals (starting from two-three hours to two-three days) of heavy rainfall have elevated, placing India’s rain-fed areas at larger threat concurrently of each drought in addition to cloudbursts and rain-induced flash floods.

“We’ve noticed that there’s this enhance in short-span heavy rainfall occasions notably in central Kerala, within the districts of Idukki, Kottayam, Pathanamthitta and Ernakulam,” Koll stated. “Flash floods and landslides have turn out to be extra widespread as a result of these heavy rains, aggravated by adjustments in land use patterns, deforestation in favour of monoculture (like Idukki’s tea, rubber and cardamom plantations) and extra quarrying. Greater than half of the forest cowl downstream of the place the dam is now has been misplaced since 1900.”

Within the short-term, Koll recommends that governments can handle potential disasters higher by integrating rain forecasts from the Indian Meteorological Division with higher calibrated reservoir administration and water discharge techniques. Because of this a number of departments on the Centre and each states should be prepared to reply collectively, and speedily, to handle adversarial climate occasions sooner or later.

Unsafe practices

The CWC official quoted earlier stated that a lot of this data is already with Kerala. The state, nonetheless, is commonly reluctant to share it with Tamil Nadu. “Kerala has put in some instrumentation to gauge the water influx upstream on the confluence of the Mullayar and Periyar rivers (the dam is constructed at their confluence), the influx into the dam, the rainfall within the catchment space, and many others. Kerala must make this accessible to Tamil Nadu on a real-time foundation so (the latter) can plan the water discharge higher.”

With the 2 states at loggerheads and neither prepared to compromise on its place with out dropping face electorally, the CWC hopes that the brand new Dam Security Act, 2021, will power a rapprochement.

Whereas dams have to date been underneath the respective state’s regulatory management, the regulation mandates periodic security audits and stability strengthening work as really helpful by the newly constituted nationwide dam security authority. “Earlier, we may solely suggest security tips to states, and never guarantee compliance. With this Act, non-compliance turns into a felony offence,” the CWC official stated.

On 8 April, the supreme court docket additional empowered the supervisory committee with interim capabilities and powers equal to the Nationwide Dam Security Authority, a brand new physique proposed underneath the 2021 Act.

Ending hostilities

At Vallakkadavu, a village that may be a little over 4 km downstream from the dam, lives 68-year-old Abu Bakr. He remembers fishing along with his mates within the dam waters as a teen, a time when locals may freely entry this neighbourhood reservoir. At present, the dam can not be approached from the Kerala facet, by native residents, authorities officers and even politicians.

Again within the ‘90s, Abu Bakr had been employed as labourer by the Tamil Nadu public works division for restore and structural strengthening work on the dam. Of the a number of Idukki residents Mint interviewed within the villages downstream to the Mullaperiyar, Abu Bakr was one in all solely two who has ever visited the dam (the opposite is a retired police constable).

I ask if he’s fearful of the dam bursting one night time. “Not likely,” he responds. “I’ve seen the dam; I do know it’s robust. However my kids are very frightened; they haven’t seen it from the within and so they think about the worst.”

Today, Abu Bakr runs a small roadside store, constructed off a ledge under which runs a stream, an insignificant offshoot of the mighty Periyar that the 2 southern states are battling over. In March, because the summer time warmth gathers power in Kerala, the stream is bone dry.

“Within the monsoon, when the water is launched from the dam, we aren’t warned upfront,” Abu Bakr stated. “We solely discover out when the roads are flooded and the bridge is submerged, and naturally, we’re all offended once more. I’m shocked you’re right here in the summertime. The politicians come throughout the rain. For the remainder of the 12 months, no person cares.”
