Indonesia’s mangroves store large amounts of carbon, and saving them could help the country reduce greenhouse gas emissions, a new research paper has found. The mangroves store about 3.14 billion tonnes of carbon, equivalent to about one-third of the carbon stored in the world’s coastal ecosystems, according to the paper co-authored by scientists at the Center for International Forestry Research (CIFOR).“We hope that these numbers help policymakers see mangroves as a huge opportunity for climate change mitigation,” says Mr Daniel Murdiyarso, principal scientist at CIFOR and lead author of the paper.
