Main Body

Geographical factors:

[Diagram present showing land-ocean interface with mangrove zone marked]

Mangroves represent ecotone.

Geographical factors:

1Ecotone climate & geographical conditions => inundation of fresh and salt water => brackish water zone.

2Humid climate, with heavy rainfall.

3Deltaic areas, rich in terrestrial deposits carved by rivers & marine deposits carved by ocean tides.

4Water-logged soils.

Threat to Mangrove forests:

Climate change is threatening warming of atmosphere by 1.5°C (as per IPCC report).

Significant impact on mangroves:

1Rising sea level due to melting of glaciers => submergence of mangrove forests.

2Net carbon source => if wetlands are mangroves are disturbed, they have potential to release 4000 tonnes of sequestered CO2 => further warming of climate.

3Coastal erosion caused due to frequent tropical cyclones and storms.

4Rising salinity of oceans => extreme salt can lead to death of mangrove bay tides => mangroves are integral to weather of planet scheme like MISHTI, magical mangrove campaign conservation and management of mangroves aim to protect the vital ecosystems.
