A number of challenges are faced by practitioners seeking to elicit values associated with water in a world of global change. These values are needed to assist in decision-making around the use of water as a country’s key asset. Five different pathways show the complexity of the relationship between global change and environmental valuation of water: a climate change pathway, ecosystem infrastructure pathway, population/demographics pathway, income pathway, and technological change/innovation pathway. The challenges are most acute for water when it is related to ecosystem services since values need to be elicited through the use of non-market survey-based valuation techniques. In addition, environmental valuation will be important to inform the determination of water quality standards associated with different uses of water (drinking, recreation, etc.) and the allocation of resources to provide these different services. Several case studies illustrate issues and solutions. The article concludes with an appreciation of future challenges and opportunities.

Benefit transfer is the projection of benefits from one place and time to another time at the same place or to a new place. Thus, benefit transfer includes the adaptation of an original study to a new policy application at the same location or the adaptation to a different location. The appeal of a benefit transfer is that it can be cost effective, both monetarily and in time. Using previous studies, analysts can select existing results to construct a transferred value for the desired amenity influenced by the policy change. Benefit transfer practices are not unique to valuing ecosystem service and are generally applicable to a variety of changes in ecosystem services. An ideal benefit transfer will scale value estimates to both the ecosystem services and the preferences of those who hold values. The article outlines the steps in a benefit transfer, types of transfers, accuracy of transferred values, and challenges when conducting ecosystem transfers and ends with recommendations for the implementation of benefit transfers to support decision-making.

The recent implementation of the IPBES is a major cornerstone in the transformation of the international environmental governance in the early 21st century. Often presented as “the IPCC (Intergovernmental Panel on Climate Change) for biodiversity,” the IPBES aims to produce regular expert assessments of the state and evolution of biodiversity and ecosystems at the local, regional, and global levels. Its creation was promoted in the 1990s by biodiversity scientists and NGOs who increasingly came to view the failure of achieving effective conservation of nature as the consequence of the gap between science and policy, rather than of a lack of knowledge. The new institution embodies an approach to nature and nature conservation that results from the progressive evolution of international environmental governance, marked by the notion of ecosystem services (i.e., the idea that nature provides benefits to people and that nature conservation and human development should be thought of as mutually constitutive). The IPBES creation was entrusted to the United Nations Environment Programme (UNEP). Social environmental studies accounted for the genesis and organization of the IPBES and paid special attention to the strong emphasis put by IPBES participants on principles of openness and inclusivity and on the need to consider scientific knowledge and other forms of knowledge (e.g. traditional ecological knowledge) on an equal footing. Overall the IPBES can be considered an innovative platform characterized by organizations and practices that foster inclusiveness and openness both to academic science and indigenous knowledge as well as to diverse values and visions of nature and its relationship to society. However, the extent to which it succeeded in putting different biodiversity values and knowledge on an equal footing in practice has varied and remains diversely appreciated by the literature.
