Carbon Sequestration – Working Copy

The Carbon sequestration power of coastal wetlands


 In the face of global warming, coastal wetlands—including submerged seagrasses, mangrove forests, and salt marshes, and pelagic ecosystems—provide a vital service to the global community by storing large amounts of carbon.

Our Projects

Global Mangrove Biomass

Working with partners in the University of Cambridge, we conducted a review of all the available science and developed a model describing the relationship between mangrove biomass and climate (temperature, rainfall and seasonality).

The results of the study confirmed that mangroves are a biomass powerhouse, but it also called out the most valuable areas of all. This knowledge can be translated into action. For the countries with high biomass value such as Indonesia, Brazil and Nigeria, including mangroves in national policies could yield beneficial results in offsetting a certain amount of their greenhouse gas emissions. For smaller island countries, like Cuba and Solomon Islands, mangroves may represent a significant portion of their total forest. When thinking about ways to finance conservation, market-based mechanisms may provide a significant opportunity as they represent one of the islands’ large assets.

Blue Carbon in Australia

Our Australian project focuses on modelling and mapping the social and economic values of saltmarsh, seagrass and mangrove habitats through fisheries, recreation, tourism, blue carbon and coastal protection. We use a geographically nested, case study approach with a focus on marine habitats that occur in central Victoria and northern New South Wales, specifically Port Phillip Bay and Western Port Bay (Victoria) and the Richmond River/Tuckean Swamp estuary (NSW).  Read more here.
