Urban water quality and the Triple Bottom Line - Can we reconcile the irreconcilables?
Goonetilleke, Ashantha & Thomas, Evan C. (2003) Urban water quality and the Triple Bottom Line - Can we reconcile the irreconcilables? In Douglas, Bob, Furnass, Bryan, & Goldie, Jenny (Eds.) In search of sustainability, February to November 2003.
The adoption of a triple-bottom line approach is advocated to safeguard urban water quality. Ecosystem functions need to be addressed initially followed by social and then economic needs. This calls for a cultural change towards urban water resources rather than the current piecemeal approach. Water and water environments are valuable community assets. Urban land use coupled with anthropogenic activities alters the stream flow regime and degrade water quality. Urban water pollution is difficult to cost in terms on conventional monetary measures. True costs extend beyond immediate human or the physical boundaries of the urban area and affect the function of surrounding ecosystems. Current approaches to safeguard water quality are largely ineffective. They are generally based either on, insufficient design knowledge, faulty value judgements or inadequate consideration of life cycle costs. The problem of urban water pollution can only be remedied through innovative planning and the courage to implement sustainable practices.
Impact and interest:
Citation countsare sourced monthly fromand 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.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
