Environment, Disaster Management and Contemporary Issues
What to master
Ecology basics: ecosystems, food chains, biodiversity hotspots (Western Ghats, Eastern Ghats, Sundarbans, Himalayan), and conservation laws (Wildlife Protection Act 1972, Forest Conservation Act 1980, Biological Diversity Act 2002, Environment Protection Act 1986). Climate change: greenhouse gases, COPs, Paris Agreement, net-zero by 2070. Pollution and waste management. Disaster management: types (cyclones, floods, earthquakes, droughts), the Disaster Management Act 2005, NDMA, NDRF, and Sendai Framework (2015–2030). AP specifics: cyclone-prone Bay of Bengal coast, Godavari/Krishna floods, drought in Rayalaseema, and the Cyclone Warning Centre at Visakhapatnam.
Traps that recur
- NDMA (policy, 2005 Act) vs NDRF (response force) vs NIDM (institute).
- Sendai Framework (disasters, 2015–30) vs Paris Agreement (climate, 2015) - both 2015.
- Biodiversity hotspots: India has four - Himalayas, Indo-Burma, Western Ghats–Sri Lanka, Sundaland (Nicobar). Eastern Ghats is not a hotspot.
- Pollutant standards: PM2.5 vs PM10 sizes swapped.
- Confusing mitigation (reduce risk) with adaptation (adjust to impact).
Rule of thumb
For disaster questions, use the "phases" grid: mitigation → preparedness → response → recovery. Then match the institution: NDMA (policy), NDRF (response), NIDM (training).
Worked example
"Which framework guides global disaster risk reduction 2015–2030?" - Sendai Framework. Trap: choosing the Paris Agreement because both are 2015; Paris is climate, Sendai is disasters.
