Act now on wetlands for Agenda 2030s All major global policy agreements conclude: Wetlands are vital ecosystems in the landscape and are indispensable to achieve a sustainable and secure world. Wetlands and Sustainable Development Yet, 64% of wetlands have been lost since 1900 through Wetlands link and regulate water in our landscapes, from drainage and conversion and much of those that remain are mountains to the sea. They act as water sources, sinks and under growing pressure from economic and infrastructure purifiers. They protect our shores, help make cities and development that has failed to value their role. This makes settlements safe and resilient and help recover after disaster people and nature vulnerable. strikes. They are Earth’s greatest natural carbon stores. They support abundant and unique nature. They are vital to reverse The world needs landscape scale and system approaches that land degradation and desertification. They are centres of take full account of wetlands interactions and the full range of economic growth, and the engines for the local economy. They benefits these provide to society and nature. Such approaches are the sources for plentiful food and fish, clean drinking water are cost-effective, flexible and ‘no regret’ options. and sanitation services. Global policy commitments on wetlands have been made for a number of interlinked purposes Now global policy frameworks acknowledge this and give all countries the responsibility to mainstream the protection and restoration of wetlands or freshwater systems and their services as a vital strategy for a sustainable and secure world: Reduce disaster Reduce CO2 risks Sustainable food emmisions production systems Adaptation to climate Conserve, restore and Achieve sustainable change impacts sustainably use wetlands development Combat Halt biodiversity desertification Water security and Halt and reverse land loss sanitation degradation It’s time to transform our world...
