Raigad landslide brings back focus on Madhav Gadgil report
GS Paper - 1 (Geography)
A landslide in Maharashtra’s Raigad district claimed 27 lives, flattened an entire village, and brought back into focus the 2011 Dr Madhav Gadgil report on conservation of the Western Ghats. Deputy chief minister Devendra Fadnavis said as per the recommendation of the report, the mapping of all the landslide-prone villages in the state, including those on the Western Ghats, was carried out during his tenure as the Chief Minister of the state between 2014 and 2019 and was submitted to the Union government.
What does the report state?
In 2010, then Union Environment Minister Jairam Ramesh appointed the Western Ghats Ecology Expert Panel (WGEEP), to be chaired by ecologist Dr Madhav Gadgil. The commission submitted its 552-page report to the Centre in August 2011.
The report recommended classifying 64 percent of the Western Ghats, spread over six states, into Ecologically Sensitive Zones called ESZ 1, ESZ 2 and ESZ 3. It also recommended designating the entire region as an Ecologically Sensitive Area (ESA).
Almost all developmental activities like mining, construction of thermal power plants, dams were to stop along with the decommissioning of similar projects that have completed their shelf life in ESZ 1.
It said that both the Athirappilly and Gundia hydel project sites should not be accorded environmental clearance as they fall in this zone.
For Goa, WGEEP recommended an indefinite moratorium on new environmental clearances for mining in ESZs 1 and 2, a phasing out of mining in Ecologically Sensitive Zone 1 by 2016, and continuation of existing mining in Ecologically Sensitive Zone 2 under strict regulation with an effective system of social audit.
In the Ratnagiri and Sindhudurg districts of Maharashtra, the panel advised that in ESZs 1 and 2, no new polluting (red and orange category) industries, which would include coal-based power plants, should be permitted to be established, and the existing red and orange category industries should be asked to switch to zero pollution by 2016.
Further, it found that plains and coastal tracts in these districts were under “severe environmental and social stress”.
In all the zones, genetically modified crops should not be allowed, use of plastic bags be prohibited, Special Economic Zones should not be permitted, new hill stations should not be allowed, changing the land use from farmland to non-farm land and the stoppage of diversions of rivers to protect the ecology of the region, and public lands should not be converted into private lands.
The report also suggested a bottom-to-top approach instead of a top-to-bottom approach in governance of the environment, indicating decentralization and more powers to local authorities.
It recommended theestablishment of a Western Ghats Ecology Authority under the Environment (Protection) Act, 1986, as a professional body to manage the ecology of the region and to ensure its sustainable development.
What was the need for this report?
The Gadgil commission was formed by the Ministry of Environment in 2010 to study the impact of population pressure, climate change and development activities on the Western Ghats.
Accorded the World Heritage status by UNESCO, the Western Ghats are a 1,600-km-long mountain chain running the western coast of the country covering six states — Gujarat, Maharashtra, Goa, Tamil Nadu, Karnataka and Kerala.
These Ghats are home to high mountain forests, which moderate the tropical climate of the region and present one of the best examples of the monsoon system on the planet.
They are home to 325 globally threatened flora, fauna, bird, amphibian, reptile and fish species. About 60 percent of the mountain range is in Karnataka.

Key takeaways of WMO report
GS Paper - 3 (Environment)
According to a new report, released by the World Meteorological Organization (WMO), Asia is the world’s most disaster-prone region and it experienced 81 weather, climate and water-related disasters in 2022. These events directly affected more than 50 million people with about 5,000 getting killed and economic damage worth $ 36 billion, the report added. Although, in 2021, the continent had been affected by around 100 natural disasters, the extent of these hazards was more prominent in 2022 — the number of people and facilities affected, and economic damage has increased.
What are the key takeaways from the report?
According to the report, while the mean temperature over Asia in 2022 was about 0.72 degree Celsius above the 1991–2020 average, it was about 1.68 degree Celsius above the 1961–1990 average.
This rise in temperatures has had some severe fallouts, including an uptick in the occurrence of extreme weather events.
For instance, droughts ravaged numerous parts of Asia in 2022. China particularly suffered the most as last year, the Yangtze River Basin, located in the country’s southwest, experienced the worst drought in the last six decades.
This not only affected crops and vegetation, as well as the drinking water supply but also caused an economic loss of about $ 7.6 billion.
Many other regions were hit by severe floods and extreme monsoon rainfalls. Pakistan is the most notable example – it received 60 percent of normal total monsoon rainfall within just three weeks of the start of the 2022 monsoon season, and the heavy rains resulted in urban and flash floods, landslides, and glacial lake outburst floods across the country.
More than 33 million people were affected, over 1,730 people died and almost eight million people were displaced, according to the report.
Apart from natural disasters, climate change has exacerbated glaciers melting in Asia due to high temperatures and dry conditions.
Four glaciers in the High Mountain Asia region, centred on the Tibetan Plateau, have recorded significant mass losses, with an accelerating trend since the mid-1990s.
At the same time, these four glaciers show an overall weaker cumulative mass loss than the average for the global reference glaciers during the period 1980–2022.
Even thesea surface temperatures in Asia are getting warmer than ever before. The report pointed out that in the north-western Arabian Sea, the Philippine Sea and the seas east of Japan, the warming rates have exceeded 0.5 degree Celsius per decade since the 1980s. It is about three times faster than the global average surface ocean warming rate.
India in report
In India, heavy rainfalls “lasting from May to September triggered multiple landslides and river overflows and floods, resulting in casualties and damage”.
In total, this flooding resulted in over 2,000 deaths and affected 1.3 million people — the disaster event caused the highest number of casualties of any disaster event in 2022 in India.
The report also said economic loss due to disasters relating to floods exceeded the average for the 2002–2021 period. Pakistan incurred a loss of over $ 15 billion, followed by China, over $ 5 billion, and India, over $ 4.2 billion.
Another extreme weather event that became a mainstay in Asia last year was heat waves.
The report noted that India and Pakistan experienced “abnormally warm conditions” in the pre-monsoon season (March–May), the report mentioned. China, Hong Kong and Japan also saw the mercury rising to record high levels in 2022.
