Freshwater Ecosystem Services

Freshwater ecosystems cover just 12.8 million square kilometers of the planet’s surface that are home to some of the greatest concentrations of species and provide services without which life would not be possible. These systems are unfortunately under great threat. More than half of our planet´s wetlands have been lost and freshwater biodiversity has declined at an alarming rate. With increasing degradation and loss of freshwater ecosystems, loss of related services are also likely to occur. If the current trend continues, by 2050 we will have lost 11% of the remaining natural areas that are crucial to ensure the supply of ecosystem services.

Ecosystem services provided by freshwater systems are shown below:

* The above table shows the ecosystem services provided by freshwater systems. Many valuation studies of the services have not been completed. Green highlights show ecosystem service and freshwater system combinations for which economic values are available.
