Several authors call for concern about using economic valuation of ecosystem services for biodiversity conservation, such as this recent piece in Science. In today´s blog post, we would like to emphasize that valuation of ecosystem services is only one of the many facets that could be considered for biodiversity conservation and sustainability:
It is important to distinguish between the ecosystem services concept, biophysical or socio-cultural assessment of services, economic valuation, and related policy instruments. Valuing services can contribute to slowing down ecosystem degradation. Unfortunately, economic valuation is often used beyond its reasonable scope.

We relate the limits and opportunities of ecosystem services assessment and valuation to three hierarchical goals of sustainability, which Herman Daly in a seminal paper has sketched: ecological scale, fair distribution and allocative efficiency. Lacking enforcement of ecological scales in market systems leads to crossing planetary boundaries. Hence, first, the scale of permissible human activities needs to be established within ecological limits. This involves societal choice on the extent of conservation and sustainable ecosystem use. Decision making can benefit from assessments that determine the carrying capacity of ecosystems, but there is no role for economic valuation in determining ecological limits. Second, access to services is often distributed unequally, as the Millennium Ecosystem Assessment has already pointed out. Societies need to determine a fair intra- and intergenerational distribution of natural resources. This could be done by developing social capital, including rules and norms to manage local commons. Policy instruments should establish fair benefit and burden sharing of conservation and sustainable ecosystem use, while ensuring participation of all stakeholders. Ecosystem service assessments can reveal spatial and temporal service flows and assist in establishing policy instruments. In third place only, once scales are established and fair distribution is achieved, resources can be efficiently allocated to their best societal use to prevent wasting scarce resources. This could be assisted by ecosystem service valuation. Ecosystem service assessments, but not necessarily valuation, can thus contribute to achieving sustainability. If conceptual synergies with the ecosystem services concept are recognized, biodiversity conservation can thus be supported, even though not all reasons one may have for conservation are captured by the anthropocentric concept of ecosystem services.
