Eye in the sky to watch Maharashtra mangroves

#GS3 #ENVIRONMENT #MANGROVES 

News info:

  • 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.

BIASA BASICS 

Mangroves

  • 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.
