Idukki dam opened after 26 years

Though 27 small and big dams were opened across Kerala in this crisis, the opening of the Idukki dam's shutters at Cheruthoni gained media and public attention. Idukki is the biggest arch dam in Asia and the last time this dam's shutters were opened was in 1992.

In the wake of the heavy rains this year, the water level in the dam had reached almost 2,400 feet, just a few feet lower than its maximum capacity of 2403 feet. On August 9, following a warning to the public, the officials opened shutters of the dam, after 26 years.

It was first time in the history that all five shutters of the dam were opened. After the shutters were opened it cause rapid swelling of Periyar river that flows through Idukki and Ernakulam districts. Nearly 700,000 litres of water per second was discharged from the Idukki dam into the Periyar river.

"Because of torrential rains and landslides, 18 relief camps have been started in different parts of Idukki district and almost 1,000 people have been relocated to these camps. Opening of the shutters of Cheruthoni dam due to increased water level of Idukki dam has also resulted in people being moved to camps. We have taken enough measures to provide all the necessary facilities for the affected people," Idukki district collector D. Balamurali said.

Environmentalists point at poor policy decisions

Most of the regions impacted by this monsoon were once classified as ecologically-sensitive zones (ESZs) by the Western Ghats Ecology Expert Panel (WGEEP), also known as the Gadgil Committee.

The report was crafted by a team headed by Madhav Gadgil, ecologist and founder of the Centre for Ecological Sciences at the Indian Institute of Science, Bengaluru. According to environmentalists, the committee's recommendations were strong enough to protect the sensitive Western Ghat region.

The committee had suggested that 140,000 kilometres of the Western Ghats be classified in three zones as per the requirement of environmental protection in the areas. In some areas the committee recommended strong restrictions on mining and quarrying, use of land for non forest purposes, construction of high rises etc. The report was first submitted to the government in 2011.

But the Kerala government rejected the committee report and did not adopt any of its recommendations.

Speaking to various regional media, Madhav Gadgil has said that irresponsible environmental policy is to blame for the recent floods and landslides in Kerala. He also called it a "manmade calamity". He said that the committee report had recommended to protect the resources with the cooperation of local self governments and people, but those recommendations were rejected. He also pointed out that quarrying is a major reason for the mudslides and landslides.

Other environmentalists also point fingers at the extensive quarrying, mushrooming of high rises as part of tourism and illegal forest land acquisition by private parties as major reasons for the recent calamity.
