Sustainable Development and Environmental Management
What this domain tests
Sustainable Development and Environmental Management tests the meaning of sustainability, international milestones, environmental management tools (EIA, EMS, auditing, cleaner production) and their application in Rajasthan. Expect definitional precision and questions about which tool fits which stage of a project.
Core rules and concepts
- Brundtland Report (1987): development that meets present needs without compromising future generations; three pillars - environmental, social, economic.
- Milestones: Stockholm 1972, Rio Earth Summit 1992 (Agenda 21, UNFCCC, CBD), Kyoto 1997, Paris 2015, SDGs 2015 (17 goals, 169 targets).
- EIA is a process of prediction and consultation before approval; it is not the same as clearance. Steps: screening, scoping, baseline, impact prediction, mitigation, public hearing, decision, monitoring.
- Environmental management: ISO 14001 EMS (plan–do–check–act), environmental audit, cleaner production, life-cycle assessment, 3R, carbon and ecological footprints.
- Rajasthan applications: solar parks, watershed development, joint forest management, industrial estates with common effluent treatment, mining reclamation.
- Sustainable management maintains natural capital within limits; it does not mean preserving everything untouched.
Worked example
A household uses 100 kWh of grid electricity per month; the grid emission factor is 0.8 kg CO₂ per kWh. Carbon footprint from electricity = 100 × 0.8 = 80 kg CO₂ per month. Reasoning: multiply activity data by an emission factor; the factor must match the grid and units. If 20 kWh is replaced by rooftop solar, the saving is 20 × 0.8 = 16 kg CO₂.
Traps
Calling EIA a clearance certificate; treating ISO 14001 as a performance standard (it certifies a management system); mixing Agenda 21 with the SDGs; claiming sustainability means zero resource use. Match the tool to the stage: prediction, operation, audit or certification.
