Sounds of silence: a forest that survived 'development' (downtoearth)

Silent Valley National Park reinforces the fact that forests and their resident biodiversity are our greatest wealth

Since the day I was assigned to write about Kerala’s Silent Valley National Park, a 90-sq km stretch of tropical evergreen forest tucked in the Western Ghats, I have been asked a question over and over again: why is it called Silent Valley? It is a peculiar name in a country like ours. There are more than 100 national parks in India, most of them named after either a physical feature like a river or a mountain; a historical or mythological place or character; an animal; or a former prime minister. Only two names inspire the imagination: the Valley of Flowers National Park in Uttarakhand and Silent Valley.

In a booklet titled “Storm Over Silent Valley”, senior environmental journalist Darryl D’monte notes its widely accepted etymology. The valley was originally known as Sairandhri, another name for Draupadi, the wife of the Pandavas. And the river flowing through it is called Kunthipuzha, after their mother. When an Englishman, who discovered this virgin forest in colonial times, found that that there was no white noise of the cicadas after dark, common in other forested areas, he renamed it the Silent Valley.

A special forest no one has heard of

Silent Valley is one of India’s few rainforests. D’monte writes that it would be more correct to call it a shola forest, a type of vegetation found only at the base of valleys in the western hills of south India. Surrounded by high ridges, the forest is deep and virtually impenetrable. So secluded is Silent Valley that there is no written record of any human habitation in its core area. While there are some tribal settlements in the buffer zone, the mere fact that the forest is unspoilt by humans is enough to raise my suspense. I am also eager to visit the site of the first and most bitterly fought environment v development debate in India.

I arrive in Coimbatore, Tamil Nadu, and decide to hire a taxi to Mukkali, the base camp of the Silent Valley National Park, around 62 km away. Armed with a 20-word-strong Tamil vocabulary generously sprinkled with English, I start asking around for a way to the park. But the mention of Silent Valley invites raised eyebrows and casual shrugs from taxi drivers and shopkeepers alike. No one has heard of it before. I thought that the city’s taxi drivers would be used to a steady stream of tourists and nature enthusiasts headed for the national park. They are not. I cannot blame them though. Eleven years ago, I spent three days reporting on tribals as a student in Attapadi, within a whispering distance of Silent Valley. Apart from a passing reference to the forest, I had then remained largely indifferent to its momentous environmental history. With so much written and spoken about this forest, why is Silent Valley still unknown to or underappreciated by people? Is the valley’s silence a boon or a curse?

“I first heard about Silent Valley in 1972 when a newspaper article announced the Kerala government’s plan to build a hydropower project over the Kunthipuzha,” says M K Prasad, one of the pioneers of the Save Silent Valley movement. He was then a teacher of botany at a college in Kozhikode. When he visited the forest, he realised that building a dam would be nothing short of a blunder. “The forest was impenetrable and largely undisturbed. If the dam had been built, it would have started degrading the forest system slowly and we would have lost the entire forest over a period of time,” he adds.

The idea for a dam had taken root in the 1920s. The natural drop of the Kunthipuzha river, as it flows into the plains, is the highest in Kerala at 857 metres, making it the ideal site for a hydropower project. After Independence, multi-purpose river valley projects became a top priority to fulfill the country’s requirements for irrigation and electricity. So much so that by 1979, Government of India had invested nearly 14 per cent of the total planned expenditure on dams and canals. One of these projects was in Silent Valley; a 131-metre-high dam, which would generate 240 MW of electricity and irrigate 10,000 hectares of land in Kerala’s Palghat and Malapuram districts. The project was, however, never to be.

One of a kind

Back in Coimbatore, I finally find a taxi driver who offers to take me to Mukkali by following the route on Google Maps. Soon enough, we are going up and down winding roads in the countryside from Tamil Nadu to Kerala. Banana, coconut and areca nut plantations line the road, protected by electric fencing to keep elephants from destroying the crop.

NGT terminates chairmen of pollution control boards in 10 states (downtoearth,)

Cracking the whip on 10 State Pollution Control Boards (SPCBs) for ad-hoc appointments, the National Green Tribunal has ordered the termination of Chairpersons of these regulatory authorities. The concerned states are Himachal Pradesh, Sikkim, Tamil Nadu, Uttarakhand, Kerala, Rajasthan, Telangana, Haryana, Maharashtra and Manipur. The order was given last week by the principal bench of the NGT, chaired by Justice Swatanter Kumar. The recent order of June 8, 2017, comes as a follow-up to an NGT judgment given in August 2016. In that judgment, the NGT had issued directions on appointments of Chairmen and Member Secretaries of the SPCBs, emphasising on crucial roles they have in pollution control and abatement. It then specified required qualifications as well as tenure of the authorities. States were required to act on the orders within three months and frame Rules for appointment [See Box: Highlights of the NGT judgment of 2016 on criteria for SPCB chairperson appointment]. Having

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i
