Revision summary
Natural disasters come from earth, weather, and ecology; man-made ones from industry, fire, and conflict. Compound events mix both, as when a flood hits a badly sited plant. The Disaster Management Act, 2005 built NDMA, SDMAs, DDMAs, and NDRF. Cyclone warning and evacuation show the system at its most effective. Urban floods, landslides, and chemical-fire compliance are the remaining effectiveness gap.
Model answer
Introduction
A disaster is a serious disruption that a community cannot absorb with its usual means. Natural disasters come from earth, water, wind, and disease ecology. Man-made disasters come from industry, transport, fire, and conflict. India’s system after the Disaster Management Act, 2005 is stronger on cyclones than on urban floods or chemical plants, which is the honest measure of effectiveness.
Body
Distinction
- Natural: earthquake, cyclone, flood, drought, landslide, heatwave, and some epidemics — hazards of the physical and biological environment.
- Man-made (anthropogenic): industrial chemical leak, nuclear accident, major fire, structural collapse, oil spill, and terror or conflict mass-casualty events — hazards of technology and intent.
- Some events are compound: a flood that drowns a poorly sited factory is natural weather plus man-made land use.
India’s disaster management system
- The 2005 Act created NDMA at the Centre, SDMAs in States, and DDMAs in districts, with a shift from relief-only to mitigation, preparedness, and response.
- NDRF, SDRF, IMD, INCOIS, and the National Disaster Management Plan are the operational and warning spine.
- Effectiveness that is real: cyclone death tolls on the Odisha–Andhra coast fell sharply after early warning, evacuation, and shelters — a global teaching case.
- Heat action plans, drought manuals, and school-hospital retrofits exist on paper and, in some cities, in drills.
Where effectiveness is still thin
- Urban flood and Himalayan landslide expose land-use failure that no NDRF column can fully offset on the day.
- Industrial and chemical off-site plans, and fire-code enforcement, remain the weak man-made half.
- Finance, district capacity, and inclusion of persons with disability and migrants are uneven, so a national Act is not a uniform local system.
India’s DM system is therefore effective as a cyclone-and-rescue state, and only partly effective as a risk-reduction and man-made-hazard state.

Conclusion
Natural disasters arise from environmental hazards; man-made disasters arise from technology, negligence, or violence. DMA 2005, NDMA, and NDRF have made India more effective at warning and cyclone evacuation. Effectiveness is weaker on urban flood, mountains, and chemical-fire risk, which still need land-use and compliance, not only rescue.

-
Is a drought a disaster if it develops slowly?
Yes. Indian law and practice treat drought and heat as disasters even when they are not a single-night event.
-
Does NDRF mean the system is complete?
NDRF is response. Completeness needs building codes, buffers around factories, and drainage that prevent the call-out.

Evaluate the policies of the Government of India regarding the promotion of food processing and related industries.
Food processing
Food-processing policy now sits on PMKSY parks and cold chains, PLI for organised lines, and PMFME for micro units. Operation Greens and APEDA add price and export support; FSSAI sets the compliance bar. The tools have expanded capacity, but horticulture wastage and informal micro mills remain large. PLI helps scale; last-mile credit and reefer links still decide whether the farmer is paid. Evaluation: right scheme mix, incomplete last mile.

Explain the implications of using E-technology to help the farmers.
Science and technology in daily life
E-technology means price, weather, soil, and subsidy tools on a phone or kiosk. e-NAM can widen discovery; advisories cut pest and rain delay; PM-KISAN DBT and PMFBY apps cut leakage. Soil Health Cards and AgriStack can match inputs to the plot. Tenants, women, and offline villages can be excluded; logins can be captured by traders. Implication: faster markets and payments, plus a divide and a data duty.

What are the important challenges faced in the implementation of land reforms in India? Give your suggestions to remove these challenges.
Land reforms
Land reform stalled on incomplete records, oral tenancy, litigation, fragmentation, and tribal land loss. Ceiling surplus actually given is far below the statutory promise. DILRMP and SVAMITVA can match map, record, and possession. Registered leasing (NITI Model Land Leasing Act) can give cultivators credit without a title war. FRA, Gram Sabha consent, and fast tribunals complete the remaining justice piece.
