Environmental Management, Law and Sustainable Development
What this domain tests
This domain covers environmental impact assessment, environmental management systems, pollution control law, principles of environmental law and sustainable development. The exam tests named Indian laws, their years and purposes, EIA steps, the precautionary principle, polluter pays and public trust doctrine.
Core rules and concepts
- Key Indian laws include the Water (Prevention and Control of Pollution) Act 1974, Air (Prevention and Control of Pollution) Act 1981, Environment (Protection) Act 1986, Wildlife Protection Act 1972, Forest (Conservation) Act 1980 and Biological Diversity Act 2002.
- EIA steps include screening, scoping, baseline studies, impact prediction, mitigation, public hearing, appraisal, clearance and post-clearance monitoring.
- ISO 14001 is an environmental management system standard based on plan-do-check-act.
- Sustainable development meets present needs without compromising future generations' ability to meet theirs; it integrates environment, economy and equity.
- Principles include precaution, polluter pays, prevention, public participation and intergenerational equity.
Worked example
A tannery discharges effluent that causes ₹5 lakh of downstream damage, while installing treatment would cost ₹2 lakh. Under the polluter-pays principle, the tannery should bear the treatment cost and remediation rather than leaving the cost to fisherfolk and farmers. Reason: the principle internalises environmental costs. If the tannery refuses, the regulator can require treatment and compensation; the lower treatment cost also shows that prevention is cheaper than damage.
Traps that cost marks
Do not confuse the Water Act with the Environment Protection Act. EIA clearance is not a one-time permanent permission; conditions and monitoring continue. Sustainable development is not only afforestation. The precautionary principle applies when evidence is uncertain but serious harm is possible. Public trust doctrine treats certain resources as held by the state for the public.
