Mangrove vulnerability and potential carbon stock loss from land reclamation

2020/9/1Utilising carbon-rich sand mining areas for land reclamation is a common practice worldwide. Considering the capacity of the mangrove area to assimilate CO 2 in the photosynthesis process, preserving the area in the quarry and that adjacent to the coastal land reclamation site is essential.
