Wetlands provide a wide range of ecological, economic and social goods and services. Ecologically wetlands form the unique interface between water and land that supports a distinctive community of plants, including floating lilies and sedges, and animals including frogs, fish and turtles. Wetlands buffer the effects of floods, reduce erosion control, capture carbon, filter out and decontaminate pollutants and toxins, recycle nutrients and stabilize stream banks and shorelines. Wetlands store excess water and act as buffers against drought for wildlife, farmers and herders. Wetlands also provide an abundance of plant and animal produce for humans, including food, water, medicine, and material for handicrafts, furniture and construction. In recent decades wetlands have become important in irrigated farming, commercial fishing, hydro-electric power generation, wildlife conservation, tourism and recreation. Wetlands are key assets in sustainable development, poverty alleviation and the improvement of livelihoods.
