Environment and Ecology encompasses the study of natural ecosystems, biodiversity conservation, environmental degradation, climate change, and the administrative and legal frameworks governing sustainable development in India.
UPSC frequently frames questions around the operational friction between developmental infrastructure projects and ecological safeguards, testing candidates on statutory compliance and judicial mandates. Questions often require evaluating India's strategy in global climate summits alongside domestic regulatory frameworks like environmental impact assessments and forest rights implementation. The examiner expects policy-focused, balanced solutions that harmonize economic growth with conservation and community rights.
