Comment on the resource potentials of the long coastline of India and highlight the status of natural hazard preparedness in these areas.
Approach · directive: “comment / highlight”
What it asks · Two parts: the resources of India's coast (marine, mineral, energy, ports, tourism) and how prepared coastal areas are for cyclones, tsunamis, storm surges, erosion and sea-level rise.
It asks 2 things — answer each
- Comment: the resource potential of India's long coastline, living, mineral, energy, ports and tourism
- Highlight: the status of natural-hazard preparedness in coastal areas, its strengths, gaps and way forward
Open with · India's coastline of about 7,516 km holds fish, minerals, energy and trade routes, yet about 5,700 km of it is extremely vulnerable to cyclones and storm surges.
Cover
- Living resources: fisheries, aquaculture, seaweed, mangroves such as the Sundarbans and coral reefs.
- Minerals and energy: Mumbai High and the Krishna-Godavari and Kaveri basins; monazite and ilmenite beach sands of Kerala and Tamil Nadu; the Deep Ocean Mission.
- Ports and tourism: 12 major and about 200 minor ports, Sagarmala's port-led development, beaches and islands.
- Preparedness strengths: cyclone forecasts and INCOIS advisories (Phailin 2013, Hudhud 2014), a tsunami warning centre since 2007, shelters, NDMA, NDRF and CRZ rules.
- Preparedness gaps: 33.6% of the mainland coast eroding (1990–2018), mangrove loss, CRZ violations, weak building codes, patchy alerts for fishers and sea-level rise.
- Way forward: mangrove and shelter belts, the hazard line, resilient housing, village risk maps, insurance and community-led coastal zone management.
Close with · A blue economy that serves SDG 14 (life below water) must be built on SDG 13 (climate action): each port or mine on the coast needs a matching mangrove, shelter and warning.

India's coastline of about 7,516 km, with the Andaman and Nicobar and Lakshadweep islands, holds fish, minerals, energy and trade routes. Yet about 5,700 km of it is extremely vulnerable to cyclones, storm surges and heavy rain, so wealth and risk must be managed together.
Resource potential of the long coastline
| Resource | Where |
|---|---|
| Offshore oil and gas | Mumbai High; Krishna-Godavari, Kaveri basins |
| Beach-sand monazite, ilmenite | Kerala and Tamil Nadu coasts |
| Mangroves | Sundarbans, the world's largest |
- Living resources: marine fisheries, aquaculture and seaweed sustain fishing communities; mangroves and reefs act as fish nurseries and carbon sinks.
- Strategic minerals: the world's richest monazite deposits lie in Kerala's Palakkad and Kollam districts, a source of thorium for nuclear power.
- Ports and trade: 12 major and about 200 minor ports carry most foreign trade; Sagarmala pushes port-led industry, shipbuilding and coastal shipping.
- Blue frontier: the Deep Ocean Mission (Rs 4,077 crore over five years) explores the deep sea; offshore wind, tidal energy and coastal tourism add potential.
Status of natural hazard preparedness
- Cyclone warning works: after Odisha's 1999 super cyclone, forecasting improved; INCOIS advisories during Phailin (2013) and Hudhud (2014) enabled timely evacuations.
- Tsunami shield: the Indian Tsunami Early Warning Centre at INCOIS, Hyderabad, has run since 15 October 2007.
- Institutions: the National Cyclone Risk Mitigation Project, cyclone shelters and drills, NDMA guidelines, NDRF teams, and CRZ rules limiting construction near the shore.
- Gaps: about 33.6% of the mainland coastline was eroding between 1990 and 2018 (NCCR); mangrove loss, CRZ violations and dense low-lying settlement add risk.
- More gaps: weak building codes, patchy last-mile alerts for fishers at sea, and sea-level rise pushing salt into deltas such as the Sundarbans.
Way forward
- Nature-based defence: restore mangroves, dunes and shelter belts, the cheapest buffer against storm surge.
- Risk-led planning: enforce the hazard line, map risk village by village, and build cyclone-resilient housing and drainage.
- People first: insure boats and nets, give fishers satellite alerts, and make them partners in integrated coastal zone management.
A blue economy that serves SDG 14 (life below water) must rest on SDG 13 (climate action): every port or mine on this coast needs a matching mangrove, shelter and warning.
