SEEA Experimental Ecosystem Accounting
"The SEEA Experimental Ecosystem Accounting constitutes an integrated statistical framework for organizing biophysical data, measuring ecosystem services, tracking changes in ecosystem assets and linking this information to economic and other human activity.
The SEEA Experimental Ecosystem Accounting complements the SEEA Central Framework by taking a different perspective. The Central Framework looks at “individual environmental assets”, such as water resources, energy resources, etc. and how those assets move between the environment and the economy. In contrast, the SEEA Experimental Ecosystem Accounting takes the perspective of ecosystems and considers how individual environmental assets interact as part of natural processes within a given spatial area.
Ecosystem accounting takes a spatial approach and ecosystem assets are delineated as spatial areas containing a combination of biotic and abiotic components and other characteristics that function together. These ecosystem assets provide ecosystem services, which are the contributions and benefits of ecosystems to economic and other human activity. The SEEA Experimental Ecosystem Accounting has a system of accounts that present a coherent and comprehensive view of ecosystems." (https://seea.un.org/ecosystem-accounting)
