Freshwater Ecosystems

Freshwater ecosystems are habitats that are characterized by freshwater, such as lakes, rivers and wetlands. These ecosystems play an important role in providing essential natural resources, including food, water and shelter. They offer an important habitat for many plants and animals, provide recreational opportunities, and are integral to the water cycle. Freshwater ecosystems are vulnerable to environmental change and provide a key indicator of the health of the global environment. They are also essential for regulating water flow and air quality, and for providing ecosystem services such as reducing erosion and flooding, water purification, and carbon sequestration. They provide opportunities for sustainable recreation and are an important source of food, medicine and other resources to local communities.
