Definition of ecosystem services Ecosystem services are the benefits provided to humans through the transformations of resources (or environmental assets, including land, water, vegetation and atmosphere) into a flow of essential goods and services e.g. clean air, water, and food (Constanza et al. 493 0 obj <>/Filter/FlateDecode/ID[]/Index[472 36]/Info 471 0 R/Length 108/Prev 1038151/Root 473 0 R/Size 508/Type/XRef/W[1 3 1]>>stream <>/Font<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 960 540] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> 1997).

Given the complex nature of ecosystem services, economic valuation faces important challenges, including the existence of ecological thresholds and non-linearities, how to incorporate the notion of resilience of socio-ecological systems, the effects of uncertainty and scaling up estimated values of ecosystem services. <>/Metadata 2459 0 R/ViewerPreferences 2460 0 R>> %µµµµ 4 0 obj Overview of Ecosystem Services Quantification and Valuation Approaches â¢Bringing the quantitative value of ecosystem service changes into economic decision-making â¢Separate Three Types of Activities: âTaking Stock: Estimating Values for Entire Natural Capital Stock â Environmental Accounting ecosystem However, their applicability is limited only to a few ecosystem goods and services.

In general, the term âecosystem servicesâ refers to the benefits people obtain from ecosystems.
