This report presents an overview of initial economic values of the world's wetlands. The basis for this study is a database of global wetland economic values as developed by the Institute for Environmental Studies (IVM) in Amsterdam, Netherlands. The estimates in this paper show, for example, that unvegetated sediment wetlands like the Dutch Wadden Sea and the Rufiji Delta in Tanzania have the highest median economic values of all wetland types at US$ 374 per hectare per year.
