Adapting Water Systems to Climate Change: a Multi Actor - Multiple Criteria Decision Analysis in South-east Queensland, Australia
نویسندگان
چکیده
Australian water systems face a host of threats under climatic change derived from the predicted increase in extreme events. This has been exemplified in the South-East Queensland region, where drought and high volume precipitation events have led to negative social and economic impacts over the last decade. These events, and how they were initially responded to, can provide information and enhance knowledge on how to improve climate change adaptation in the future. This research employs a multiple criteria decision analysis, the analytical hierarchy process technique, to analyse the opinion of decision makers in South-East Queensland on how best to adapt stormwater systems to climate change. These infrastructures are one of the most at risk and potentially costly components of water systems under a changing climate, while these stakeholders have experienced firsthand the types of extreme events that are expected to increase in frequency. The technique has been effective in identifying clear preferences for climate change adaptation among stakeholders in three municipal bodies, elicited from a range of departments. Changes to land use control and design standards were the primarily preferred actions, suggesting an underlying belief that fundamental change is required to combat to climatic change.

Adapting to climate change in South East Queensland, Australia
There is growing recognition that regionally scaled responses will be pivotal in adapting to climate change (e.g. Kirshen et al. 2008; Reyer et al. 2012). This recognition is echoed in South East Queensland (SEQ), where rapid population growth and coastal urban centres have made it one of Australia’s most vulnerable regions and a focus for climate adaptation research. As a collection of papers,...

It is impractical to implement conservation efforts for all species due to complexity of natural systems, large scale of biodiversity issues, and budget limitations. Prioritizing species of conservation importance can alleviate this issue. Multiple interrelated criteria may be used for conservation prioritization of species. Therefore, the accurate evaluation of criteria is a multi-criteria dec...

Agriculture of the inland arid region in Xinjiang depends on irrigation, which forms oasis of Northwest China. The production and water use of wheat, a dominant crop there, is significantly affected by undergoing climate variability and change. The objective of this study is to quantify inter-annual variability of wheat yield and water use from 1955 to 2006. The farming systems model APSIM (Agr...
