Assessments and valuations
Biodiversity has a multitude of values, but society takes many of them for granted. Biodiversity and ecosystem services are treated as free goods even though we depend on them for our most basic needs – pollination, healthy soils and climate regulation, among others.
The expertise we have built at UNEP-WCMC allows us to assess the state of biodiversity and ecosystem services, and the human activities that affect them. By combining these assessments with estimates of the non-monetary and monetary values of biodiversity and ecosystem services, we can provide essential biological and economic information to help guide policy-making processes.
UNEP-WCMC and the Cropper Foundation provide the Secretariat of the Sub-Global Assessment (SGA) Network, formed as result of the Millennium Ecosystem Assessment that aimed to evaluate the consequences of ecosystem changes on human well-being. SGA Network members – both individuals and organizations – are involved in evaluations of the state of ecosystems at regional, sub-regional, national and sub-national levels, and they receive support that includes training in specific evaluation methods. The assessments they conduct can be found in the IPBES Catalogue of Assessments, which provides direct access to reports, guidelines and resources.
