Question Q.17GS1GS2

What are the geographical factors responsible for the growth of mangrove vegetation in India? Also highlight its role in coastal ecology.

Main Body

More than five states in India have geographical conditions favorable to host the 'halophytic pneumatophoric plants - mangroves'

Mangrove distribution: Kerala, Mumbai, mangrove, Ganga - Brahmaputra delta, Godavari, Sundarbans, Coromandel Coast, Andaman Coast

Geographical factors for Mangrove growth:

1Long coastline - great swarmy conditions - 7600 + km coastline

2Sediment load - from rivers (Ganga, Godavari) - brings sediment load

3Mangroves require silt and clay to survive - provided by river deltas

With insolving of salty and fresh water input - from proximity to saline waters from sea to river influx

4Tropical positioning of India - requires high temperatures (25-30°C) for survival

5Halophytic conditions - salt tolerant species - allow pneumatophores (root exposure)

Role of Mangrove in coastal ecology:

1Shields the coast - against disaster - 2004 Indian Ocean tsunami - mangrove swamps provided resilience

2Cyclone resilience (Karnataka)

2As an area of ecotone - between fresh river ecology & salty oceans - creates biodiversity rich situation (livelihood) fishing ('s hooray coast) - fish, salmon, tuna

3Wetland preservation - kidneys of earth

4Act as carbon sink - sequester carbon

5supports biodiversity - royal Bengal tiger, Sundari tree
