Climate change impacts on Australian Rangelands
The recent IPCC Fourth Assessment report concluded that Australia has significant vulnerability to the changes in temperature and rainfall projected under climate change (Hennessy et al. 2007). Agriculture and natural resources were two of the key sectors identified as likely to be affected strongly. Extensive grazing is by far the most widespread agricultural land use in Australia. Most of the...
متن کاملAustralian rangelands as complex adaptive systems: A conceptual model and preliminary results
Models that seek to guide decisions on policy in rangelands must address the close links between ecological, economic, and social processes, and the adaptation of participants through time. We used an agent-based modeling approach to implement a parsimonious conceptual model of rangelands that includes biophysical processes central to the functioning of rangelands, commercial enterprises, and i...
متن کاملLearning from episodes of degradation and recovery in variable Australian rangelands.
Land-change science emphasizes the intimate linkages between the human and environmental components of land management systems. Recent theoretical developments in drylands identify a small set of key principles that can guide the understanding of these linkages. Using these principles, a detailed study of seven major degradation episodes over the past century in Australian grazed rangelands was...
متن کاملInfluencing adaptation processes on the Australian rangelands for social and ecological resilience
Resource users require the capacity to cope and adapt to climate changes affecting resource condition if they, and their industries, are to remain viable. Understanding individual-scale responses to a changing climate will be an important component of designing well-targeted, broad-scale strategies and policies. Because of the interdependencies between people and ecosystems, understanding and s...
متن کاملQuantifying Production-Environment Tradeoffs Associated with Grazing Land Management – A Case Example from the Australian Rangelands
Contemporary Australian rangeland management is characterised by concurrent processes of a continuing intensification of land management practices and simplification of landscape ecological processes. This dual characteristic is associated with increasing levels of potential conflict between land management practices that promote improved economic performance of rangeland enterprises at the app...
