Phase IFoundation

Background

Overview

UPSC frequently examines environmental regulations, conservation efforts, and the socio-economic impacts of such policies, particularly in biodiversity hotspots like the Western Ghats. The ongoing conflict between development and conservation, and the role of expert committees and federal relations in policy implementation, are recurring themes.

Ecologically Sensitive Areas (ESAs) are ecologically fragile areas notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) under Section 3(2)(v) of the Environment (Protection) Act, 1986. They serve as buffer zones around Protected Areas or as regions of high ecological significance, aiming to regulate activities that could harm the environment while balancing conservation with local livelihoods.
