Ecosystem services are the many and varied benefits that humans freely gain from the natural environment and from properly-functioning ecosystems.
Denfinition
Per the 2006 Millennium Ecosystem Assessment (MA), ecosystem services are "the benefits people obtain from ecosystems".
Four categories
The Millennium Ecosystem Assessment (MA) report 2005 defines Ecosystem services as benefits people obtain from ecosystems and distinguishes four categories of ecosystem services, where the so-called supporting services are regarded as the basis for the services of the other three categories.The more details about the four services shows in Essential ecosystem services.
Supporting services
- These services make it possible for the ecosystems to provide services such as food supply, flood regulation, and water purification.
Provisioning services
- Food, Materials, Water, Energy...
Regulating services
- carbon sequestration and climate regulation
- waste decomposition
- purification of water and air
Cultural services
- Move, Outdoor sport...
Other Use
Economics
There are questions regarding the environmental and economic values of ecosystem services. Although environmental awareness is rapidly improving in our contemporary world, ecosystem capital and its flow are still poorly understood, threats continue to impose, and we suffer from the so-called 'tragedy of the commons'.
Management and police
Although monetary pricing continues with respect to the valuation of ecosystem services, the challenges in policy implementation and management are significant and multitudinous.
Maintain Biovdiversity
Ecosystem not only provides all kinds of biological breeding ground, what is more important for biological evolution and biodiversity, provides the necessary conditions.At the same time, the ecological system created jointly by the biological community is suitable for biological survival environment.
Climate Regulation
Ecosystem through photosynthesis can effectively slow down the global warming trend.Forest ecological system can effectively decrease the loss of regional water, but also weaken the function of rapid temperature change.
