This report is a contribution to the UN's International Year of Biodiversity and is a complement to the UNEP-hosted Economics of Ecosystems and Biodiversity (TEEB) which is bringing visibility to the wealth of the world's natural capital. It documents over 30 successful case studies referencing thousands of restoration projects ranging from deserts and rainforests to rivers and coasts.

Out of all the biological carbon (or green carbon) captured in the world, over half is captured by marine living organisms --- hence it is called "blue carbon". Although emissions reductions are currently at the centre of the climate change debate, the critical role that oceans and ocean ecosystems play has been vastly overlooked.

The Indian Ocean tsunami of 2004 and the catastrophic hurricane season in the Gulf of Mexico in 2005 have had tragic and devastating consequences for the global community and have drawn attention to the vulnerability of tropical coastal ecosystems. The lessons learnt from these events are critically relevant to future management of the coast. More than ever it is essential to consider the full value of ‘ecosystem services’ when making decisions about coastal development.
