Mangroves as Carbon Sink

Volunteers in Chargheri village of Sunderbans help in planting lakhs of mangroves which offer a dense forest cover and a rich carbon sink.

The Sunderbans is a complex network of islands set in the delta on the Bay of Bengal and spread across West Bengal and Bangladesh.

  • Blue carbon – It is coined in 2009, a term for carbon captured by and stored in the world’s ocean and coastal ecosystems.
  • Key ecosystems of blue carbon - Mangroves, salt marshes and seagrass meadows
  • These ecosystems sequester and store more carbon per unit area than terrestrial forests.

Mangroves as carbon sink – After seagrass, mangroves are the most efficient carbon trapping systems which can remove 10 times more carbon from the air than other forests.

  • While other trees release the stored carbon back to atmosphere when they die, mangroves transfer the carbon to the soil, where it stays unaffected even if the tree is destroyed.

Mangrove Initiatives

  • Mangrove Initiative for Shoreline Habitats and Tangible Incomes (MISHTI) – It was launched by India in 2023 to protect and revive mangrove ecosystems on the Indian coast.
  • Mangrove Alliance for Climate (MAC) – It was launched at CoP-27 (Egypt, 2022) to unite countries to scale up, accelerate conserve and restore the mangrove ecosystems.
  • After the devastation caused by Cyclone Amphan in 2020, West Bengal Chief Minister had announced that 5 crore mangroves would be planted in the Sunderbans under the Mahatma Gandhi National Rural Employment Guarantee Act.
