‘Gadgil Committee Report’ and ‘Kasturirangan Committee Report’, sometimes seen in the news, are related to

The correct answer is protection of Western Ghats.

Both the Gadgil Committee Report and the Kasturirangan Committee Report are landmark government reports focused on the ecological protection and sustainable management of the Western Ghats — one of the world's eight biodiversity hotspots, stretching across six Indian states: Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu.

Understanding Each Report:

1. The Gadgil Committee Report (2011)
Officially known as the report of the Western Ghats Ecology Expert Panel (WGEEP), it was chaired by the renowned ecologist Prof. Madhav Gadgil and submitted to the Ministry of Environment and Forests in 2011.

Key highlights of this report include:
- It classified the entire Western Ghats region (about 1,29,037 sq. km) as an Ecologically Sensitive Area (ESA).
- It proposed dividing the region into three zones — Ecologically Sensitive Zone (ESZ) 1, 2, and 3 — with varying degrees of protection and permissible activities.
- ESZ 1 was to receive the strictest protection with a complete ban on mining, quarrying, and construction of large dams.
- The report strongly emphasized a bottom-up, community-led governance approach, involving local gram sabhas in decision-making.
- It was considered very stringent by several state governments and industry groups, which led to opposition and its recommendations not being fully implemented.

2. The Kasturirangan Committee Report (2013)
Because of the controversy surrounding the Gadgil report, the government constituted a High Level Working Group (HLWG) chaired by Dr. K. Kasturirangan, the former chief of ISRO, to review the Gadgil recommendations and submit a more balanced report. This report was submitted in 2013.

Key highlights of this report include:
- It proposed that only about 37% of the Western Ghats (approximately 59,940 sq. km) should be declared as Ecologically Sensitive Area — a significant reduction from the Gadgil panel's 100% coverage.
- It distinguished between the "natural" (forested) landscape and the "cultural" (human-inhabited) landscape, recommending strict protection only for the former.
- It recommended a ban on mining, quarrying, and large construction projects in the identified ESA but was less restrictive on the cultural zones.
- It adopted a more top-down regulatory approach compared to Gadgil's community-based model, which also drew criticism from environmentalists who felt it was too diluted.

Why the other options are incorrect:
- Constitutional reforms: Neither committee had anything to do with amending or reforming the Indian Constitution.
- Ganga Action Plan: This was a separate initiative launched in 1985 to clean and rejuvenate the Ganga river; it is unrelated to these committees.
- Linking of rivers: The interlinking of rivers project is managed under a different set of committees and government bodies, completely separate from these reports.

Key Takeaway:
Both reports are environmentally significant because the Western Ghats are home to an extraordinary range of flora and fauna, including many endemic and endangered species. They also serve as a critical watershed for peninsular India, feeding rivers like the Godavari, Krishna, Kaveri, and many others. The debate between the two reports essentially represents a tension between strict ecological conservation (Gadgil) and balanced development with selective protection (Kasturirangan) — a policy dilemma that remains relevant today. This is why both reports frequently appear in the news in the context of environmental governance in India.
