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.

The vegetated canopies for creating green spaces
GS Paper - 3 (Environment)
As Europe battles scorching temperatures this summer and wildfires blaze across the continent from the Mediterranean to Spain, the role of climate change in making heatwaves hotter and more frequent has come into focus. At a broader level, greenhouse gas emissions from human activities have heated the planet by about 1.2 degrees Celsius since pre-industrial times. These grim predictions have brought attention to a range of mitigation measures. One such initiative to bring greenery back to urban spaces in Spain involves installing vegetated awnings or canopies.
What are vegetated canopies?
Introduced in Santa Maria Street in Valladolid, Spain, the awnings are tensioned sail-like structures that have been anchored to the facades of surrounding buildings. They mimic natural canopies found in forests and various plant species.
The lightness and ease of installation of the ‘Greenshades’ allow for shade and the presence of greenery in commercial streets and public spaces, where trees or other vegetation are often absent.
Here is how they work:
The sails with anchors and supports are prepared by laying down the specific geotextile substrate or material. An irrigation system is installed at the highest side, from where the water falls by gravity, soaking the entire substrate.
In addition to water, fertilizer keeps the vegetation in perfect condition. The excess water is collected at the lowest point and into a connected drainage system.
The seed mixture is then projected onto the geotextile. After four months, the shade is expected to be completely covered with vegetation.
The awnings can be placed in streets, where planting trees may not be feasible owing to the lack of space. The plants grow hydroponically, with a water supply point and water outlet for draining purposes.
What are their advantages?
The plants chosen for these awnings belong to species that are optimised for the absorption of gases such as carbon monoxide and nitrogen oxide.
The substrate also absorbs sound waves, reducing noise pollution. A square metre of a vegetated canopy generates the oxygen required by a person for the whole year, apart from filtering harmful gases, according to the company.
The hanging planter also allows for the centralisation of water and light installations.
This is meant to induce savings as the lights are equipped with movement sensors that illuminate the street according to its need.
The adoption of such canopies could eventually contribute to urban biodiversity, creating a healthier ecosystem that supports a variety of wildlife.
