By having more than 2 million hectares of mangrove wetland area, Indonesia could play a major role in mitigating climate change. The true potential of Indonesia’s massive mangrove area has never been properly measured and because of this, the Center for International Forestry Research (CIFOR), along with the Maritime and Fisheries Research and Development Center at the Maritime Affairs and Fisheries Ministry, have launched research in several wetland areas within the archipelago. To begin the research, CIFOR scientists and staff from the ministry had installed a sedimentation and carbon stock measurement tool called the Rod Surface Elevation Table Marker Horizon (RSET-MH) in various places near the Pulau Dua coastline.
