The Gadgil Committee Report and the Kasturirangan Committee Report both focus on the conservation of the Western Ghats, one of the world's eight "hottest" biodiversity hotspots.

Gadgil Committee Report (2011) Formally known as the Western Ghats Ecology Expert Panel (WGEEP) Report, this report advocated for strict environmental protection measures across the entire Western Ghats. It recommended designating the entire region as an Ecologically Sensitive Area (ESA), divided into three zones with graded levels of regulation on development activities such as mining, construction, and deforestation. The report emphasized grassroots participation and sustainable development, but its stringent recommendations faced resistance from state governments and industries.

Kasturirangan Committee Report (2012) To review the Gadgil Committee’s recommendations, the High-Level Working Group (HLWG), led by Dr. Kasturirangan, was formed. This report sought a balance between conservation and development by proposing that only 37% of the Western Ghats be designated as ESA, focusing primarily on forest and uninhabited regions while allowing regulated development in other areas. It adopted a more lenient approach than the Gadgil Report, leading to criticism from environmentalists who argued that it diluted the conservation efforts.

In summary, while the Gadgil Report advocated for comprehensive protection with stringent regulations, the Kasturirangan Report took a more moderate stance, allowing some developmental activities while still acknowledging the ecological importance of the Western Ghats.
