Australian rangelands as complex adaptive systems: A conceptual model and preliminary results
نویسندگان
چکیده
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 institutions. The model operates on a monthly time step, and uses economic and biophysical conditions to stimulate changes in management policies and learning. Our simple model reproduces the general patterns of forage growth and livestock dynamics, and results illustrate consequences of interactions between environmental heterogeneity and learning rate.

Adaptive Policies for Reducing Inequalities in the Social Determinants of Health
Inequalities in the social determinants of health (SDH), which drive avoidable health disparities between different individuals or groups, is a major concern for a number of international organisations, including the World Health Organization (WHO). Despite this, the pathways to changing inequalities in the SDH remain elusive. The methodologies and concepts within system science are now viewed ...
متن کاملThe Paradox of Intervening in Complex Adaptive Systems; Comment on “Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation”
This commentary addresses two points raised by Kitson and colleagues’ article. First, increasing interest in applying the Complexity Theory lens in healthcare needs further systematic work to create some commonality between concepts used. Second, our need to adopt a better understanding of how these systems organise so we can change the systems overall behaviour, creates a paradox. We seek to m...
متن کاملConnections, Communication and Collaboration in Healthcare’s Complex Adaptive Systems; Comment on “Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation”
A more sophisticated understanding of the unpredictable, disorderly and unstable aspects of healthcare organisations is developing in the knowledge translation (KT) literature. In an article published in this journal, Kitson et al introduced a new model for KT in healthcare based on complexity theory. The Knowledge Translation Complexity Network Model (KTCNM) provides a fresh perspective by mak...
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 کاملTowards a Sustainable Anti-Corruption Strategy: An Ethic-Induced Model
Literature abounds to show that the current anti-corruption strategies have failed to fight corruption because of neglect of ethics in these strategies, despite its importance. The purpose of this paper is to make a contribution to anti-corruption theory by developing a model that clarifies many complex ethical dilemmas around corruption. To develop a conceptual model, the extant literatures on...
