A specific wetland programme under the UN Decade of Ecosystem Restoration would help the world reach its ambitious goals of sustainable development, halting biodiversity loss and tackling climate change, says Wildfowl & Wetlands Trust (WWT).
The call has come from organisations at a technical meeting of the Ramsar Convention, the intergovernmental treaty on wetlands.
More than a third of natural wetlands have been lost since 1970, according to figures published by Ramsar in the Global Wetland Outlook. Wetlands are being lost more than three times faster than forests.
Over the same period paddy fields, reservoirs and other artificial wetlands have nearly doubled in extent, but these man made wetlands provide relatively little benefit to wildlife and much less of the general benefits to people – such as cleaning water or preventing drought and flood.
Recent research demonstrated how natural coastal wetlands could even combat the effects of climate change.
Below are the key points organisations made in their call for governments to back the restoration of natural wetlands:
The decline of our wetlands will have serious implications on our ability to store carbon and support broader climate adaptation. By restoring, conserving, and wisely using our wetlands we can contribute towards achieving the Sustainable Development Goals (SDGs).
Natural wetlands have declined across inland, coastal and marine habitats, with serious impacts on food security, fisheries and other wetland-dependent species, water provision for agriculture and domestic needs, and as natural protection from storms and floods.
The economic and biodiversity value of wetlands far outweighs many terrestrial ecosystems – and yet they are disappearing faster than any other ecosystems.
They provide society with huge value. By degrading and draining our wetlands, we lose much more than what lives there, we also lose the diverse benefits they provide to society.
Given the important role that wetlands play in local and regional climate processes, including storing greenhouse gases, they represent an essential component of strategies for adaptation to, and mitigation of, climate change.
They can make a significant contribution to building the resilience of communities globally.Yet these systems continue to be degraded, annual rates of loss have actually accelerated in the last two decades.
We must reverse the decline of natural wetlands, and one key strategy to do that is to restore wetlands and their functions as a key ally for all countries to adapt to climate change impacts, and to help store carbon.
