Lakes, rivers, swamps, marshes, peatlands, mangroves, underground system, lagoons, shellfish & coral reefs, and kelp all constitute the global natural wetland ecosystem. Wetland protects us from floods, droughts, and other disasters. It supports biodiversity, provides
us with food and livelihoods. Wetland is the largest storage facility for carbon across among all the ecosystems.
All these wetland ecosystem services can be consolidated under the following categories Provision services (food,
fresh water, fibre, fuel, biochemical and genetic material), Regulating services
(climate, hydrology, pollution control, erosion protection, natural hazards);
Cultural services (spiritual and inspirational, recreational, aesthetic, and
educational); and Supporting services (biodiversity, Soil formation, Nutrient cycling, and pollination).
