Indonesia has the world’s fourth-longest coastline, and is home to the largest area of mangrove forests in the world. However, due to population growth and economic pressure, around 30-40% of Indonesia’s mangroves have been converted or degraded, especially since the 1970’s. Urban expansion, timber production and the development of aquaculture farms and oil-palm plantations have caused a decline of about 1.2 million hectares of mangroves since the 1980’s. According to recent estimations (2010), about 3 million hectares of mangroves are left in Indonesia, and mangroves are still being perceived as low-value forests. The Mangrove Capital project, led by Wetlands International, which started in September 2011, aims to change this perception held by government agencies, private sector and civil society. Through a partnership with Wageningen University, The Nature Conservancy, Deltares, and various local Indonesia partners, the ecological, cultural and socio-economic values of mangroves are analysed and communicated. The project will provide the knowledge and tools necessary for restoration and sustainable management of (former) mangrove areas. Almost halfway the project, an update of the work done by the Environmental Systems Analysis Group (Wageningen University) will be presented. We have identified the potential provision of key mangrove ecosystem services per management state. This enables the comparison between ecosystem services and values provided by, for instance, protected and converted mangrove areas, different aquaculture intensities and integrated silvo-fisheries. Our typology of management states is based on policy, technical, ecological and biophysical aspects and should be applicable for all of Indonesia’s coastal regions. The key services which are being quantified and valued during field studies on Java, are food (fish, shrimp, etc.), raw materials, carbon sequestration, coastal protection, water purification, nursery function, and eco-tourism. The management typology, results of the ecosystem services assessment, and preliminary findings of the fieldwork will be presented.
