Carbon Capture Potential of Peat Soils in the Abandoned Shrimp Farms of Indian Sundarbans: A Three-Decade Assessment
- 1. Department of Oceanography, Techno India University, West Bengal, EM 4/1 Salt Lake, Sector V, Kolkata 700091, India.
Description
The present study explores the carbon sequestration potential of peat soils within abandoned shrimp farms
undergoing mangrove restoration in the Indian Sundarbans. Two stations, Chemaguri and Sagar Island
(South), were selected due to historical shrimp farming practices. The study measures Soil Organic Carbon
(SOC) using the standard protocol over a 30-year timeline — 1992 (initiation of restoration phase), 2002 (10
years post-restoration), 2012 (20 years post-restoration) and 2022 (30 years post-restoration). SOC levels
increased significantly from 0.93% to 3.02% at Chemaguri and from 0.84% to 2.97% at Sagar Island
(South), indicating considerable carbon recovery due to afforestation. The findings underscore the
importance of ecological restoration in reversing soil degradation and promoting carbon capture.
