Adaptive Management of the Water Cycle on the Urban Fringe: Three Australian Case Studies Ecology and Society
Gilmour, Alistair; Macquarie University; agilmour@gse.mq.edu.au; Walkerden, Greg; Wyong Shire Council; gregw@acay.com.au; Scandol, James; University of Sydney; jscandol@bio.usyd.edu.au.
Our group at Macquarie University has run three adaptive management projects in New South Wales, Australia. Their objectives were: (1) to evaluate water cycle management strategies to minimize impacts of urban development on water quality in the Hawkesbury-Nepean basin; (2) to evaluate development planning policies to minimize water quality impacts on a series of coastal lakes; and (3) to carry out a preliminary assessment of the potential impacts of greater recreational use of Sydney water catchments. These projects are examined to evaluate the contribution of the adaptive management approach to water cycle management on the urban fringe in New South Wales. The role of the adaptive management approach in education, as a negotiation process, and in policy...

Sustaining Aquatic Ecosystems in Boreal Regions Ecology and Society
Schindler, David; University of Alberta; d.schindler@ualberta.ca.
Few boreal waters are managed in a sustainable manner, because cumulative effects of a variety of human activities are not considered. Fisheries and water quality have declined in most large water bodies of the southern boreal zone. Some of the reasons are direct, including overexploitation of fisheries, alteration of flow patterns, introductions of non-native species, and discharge of eutrophying nutrients and persistent contaminants. However, improper management of watersheds and airsheds also causes degradation of aquatic ecosystems. Clear-cut logging, climatic warming, acid precipitation, and stratospheric ozone depletion are among the more important of these indirect stressors. There are important interactions among these stressors, requiring that...

Watershed services of smallholder agriculture in the Eastern Amazon. Repositório Alice
FIGUEIREDO, R. de O.; BORNER, J.; DAVIDSON, E. A..
Abstract: Several hydrobiogeochemical research activities have been conducted in the Eastern Amazon, contributing to the understanding of how changes in forests and agro-ecosystems affect ecosystem service provision. Findings have demonstrate that good agricultural practices and the presence of natural secondary vegetation favored by smallholder farm management are important factors for hydrobiogeochemical cycling, aquatic ecosystem conservation, soil conservation, and mitigation of trace emissions from biomass burning in Amazonian small catchments. Two challenges for watershed service management arise in this context. First, low population densities and the relatively flat landscape mean that a critical mass of downstream beneficiaries of such services -...
