Global Wetland Outlook – State of the world´s wetlands and their services to people 2018
Wetlands, such as lakes, rivers, swamps, marshes, peatlands, mangroves and coral reefs provide essential ecosystem services and contributions to people’s livelihoods. Wetlands act as a source and purifier of water, they protect us from floods, droughts and other disasters, they provide food and livelihoods to millions of people, they support rich biodiversity, and they store more carbon than any other ecosystem. Yet, the value of wetlands remains largely unrecognized by policy and decision-makers. The result is that 35% of wetlands, where data is available, have been lost since 1970, at a rate three times greater than that of forests.
