Eye in the sky to watch Maharashtra mangroves
#GS3 #ENVIRONMENT #MANGROVES
- The Maharashtra Mangrove Cell has planned to accumulate a drone and found out a CCTV camera network across the MMR to stay an eye fixed on mangrove destruction by debris and land mafia.
Mum biodiversity Bachao campaign
- In an discussion hosted by NGO NatConnect Foundation, additional principal chief conservator of forests, Mangrove Cell, said the consultancy firm, Ernst & Young, would perform a survey.
- The NGO has launched a social media campaign #MumbiodiversityBachao.
- Mangroves are the plant communities occurring in inter-tidal zones along the coasts of tropical and subtropical countries.
- Mangrove forests perform multiple ecological functions like -
- Production of woody trees;
- Provision of habitat, food, and spawning grounds for fin-fish and shellfish;
- Provision of habitat for birds and other valuable fauna;
- Protection of coastlines and accretion of sediment to make new land.
- Mangroves are a various group of salt-tolerant plant communities of tropical and subtropical regions of the world which may survive the limiting factors imposed by lack of oxygen, high salinity and diurnal tidal inundation.
- consistent with Champion & Seth Classification (1968) Mangroves are included in Type Group-4 Littoral & Swamp Forests.
Mangroves cover in India
- Consistent with the India State of Forest Report, 2019, Mangrove cover within the country has increased by
- 1.10% as compared to the previous assessment.
- About 40% of the world's Mangrove Cover is found in South East Asia and South Asia.
- The mangrove cover in India is 4,975 sq km, which is 0.15% of the country’s total geographic area .
- Increase within the mangrove cover as compared to 2017 assessment: 54 sq km
- Among the states and UTs, West Bengal has the very best percentage of area under total Mangrove cover followed by Gujarat and Andaman Nicobar Islands.
Importance of Mangroves
- Mangroves have a complex root system which is extremely efficient in dissipating the ocean wave energy thus protecting the coastal areas from tsunamis, storm surge and erosion .
- Their protective role has been widely known especially after the devastating Tsunami of 2004.
- Mangrove roots hamper water flows and enhance sediment deposition.
- Therefore, they act as a zone of land accretion thanks to trapping of fine sediments including heavy metal contaminants. They also arrest coastal erosion and sea pollution .
- They act as a fertile tract for several fish species and other marine fauna.
- They act as a crucial source of livelihood for the coastal communities hooked in to collection of honey, tannins, wax and fishing.
- Mangroves are important carbon sink.
