Wetlands, as defined in Article 1.1 of the Convention on Wetlands, are exceptionally valuable ecosystems, providing a range of critical ecosystem services including carbon sequestration and storage, particularly in peatlands and coastal and marine ecosystems; ensuring safe and reliable supplies of drinking and irrigation water; many goods and services connected with food security; and management against water-related disasters such as droughts and floods (Global Wetland Outlook: Special Edition 2021).
