UPSC CSE Prelims: Preparation Strategy for Ecology, Environment and Disaster Management


Ecology and Environment is of paramount importance to any serious UPSC CSE aspirant. And the reason is – laws of nature are absolute, they cannot be bent or bribed. So you need to understand and respect in policy formulation and implementation. One amongst the reasons why so many questions are asked from this subject, and tests your applied quotients through multiple subjects like geography, economy, polity, and science and technology.

Disaster Management a relatively subdued concept has also surfaced big way in CSE. And the reason why it is clubbed with ecology and environment is because man has stepped into areas which are otherwise outbound from ecological point of view. For this you need to maintain a constant vigil and delicate balance between man’s aspirations and nature. So in case of any major ecological, geological event, you need to have a structured approach to minimise loss of life and property.
