Improving the applicability of quantitative ecological risk assessment tools-understanding demand-side changes
Gibbs, Mark T. (2010) Improving the applicability of quantitative ecological risk assessment tools-understanding demand-side changes. Human and Ecological Risk Assessment, 16(2), pp. 226-235.
Quantitative ecological risk assessment (ERA) methods are the tools of choice for many natural resource management agencies and practitioners. However, a number of researchers and practitioners have recently highlighted that the application of quantitative ERA tools has perhaps been somewhat limited and this has stimulated discussion on the limitations of these methods, considered to be supply-side limitations in this analysis. By contrast, it is argued here that the demand for risk assessment tools has also changed substantively and this also acts to limit the use of ERA approaches. In particular, demand has changed through an increasing expectation that quantitative ERA tools will be able to capture ecosystem-scale, and sometimes global-scale interactions to support ecosystem-based management approaches. Similarly, the burgeoning use of market-based policy instruments often underpinned by the allocation of private property rights to an increasing number of ecosystem goods and services has fundamentally changed many natural resource management issues into allocation conflicts between alternate rights-holders. These demand-side changes represent both an opportunity and a challenge for developers of quantitative ERA tools.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
