This paper examines how multiple criteria analysis (MCA) can be used to support multi-stakeholder environmental management decisions. It presents a study through which 48 stakeholders from environmental, primary production and community interest groups used MCA to prioritise 30 environmental management problems in the Mackay-Whitsunday region of Queensland, Australia. The MCA model, with procedures for aggregating multi-stakeholder output, was used to inform a final decision on the priority of the region's environmental management problems. The result was used in the region's environmental management plan as required under Australia's Natural Heritage Trust programme. The study shows how relatively simple MCA methods can help stakeholders make group decisions, even when they hold strongly conflicting preferences.  相似文献

On-ground natural resource management actions such as revegetation and remnant vegetation management can simultaneously affect multiple objectives including land, water and biodiversity resources. Hence, planning for the sustainable management of natural resources requires consideration of these multiple objectives. However, planning the location of management actions in the landscape often treats these objectives individually to reduce the process and spatial complexity inherent in human-modified and natural landscapes. This can be inefficient and potentially counterproductive given the linkages and trade-offs involved. We develop and apply a systematic regional planning approach to identify geographic priorities for on-ground natural resource management actions that most cost-effectively meet multiple natural resource management objectives. Our systematic regional planning approach utilises integer programming within a structured multi-criteria decision analysis framework. Intelligent siting can capitalise on the multiple benefits of on-ground actions and achieve natural resource management objectives more efficiently. The focus of this study is the human-modified landscape of the River Murray, South Australia. However, the methodology and analyses presented here can be adapted to other regions requiring more efficient and integrated planning for the management of natural resources.  相似文献

Part 2 extends the analysis to show that it is possible to find the “permission point”, the value of (the coefficient of relative) risk-aversion, at which decisions to sanction environmental protection are most likely to be made. The mathematical model describes the process by which the decision maker varies his risk-aversion over a range of feasible values to find the risk-aversion that will give him the greatest desire to invest in the protection system under consideration. If he can find such a risk-aversion before losing discrimination (because the system is too expensive, given its performance), he will adopt it as his “permission point” and decide in favour of the expenditure. The permission point is, of course, bounded above by the point of indiscriminate decision. A maximum Risk Multiplier calculated at the point of indiscriminate decision may be applied to the protection expenditure at monetary break-even to give the maximum, rational outlay on protection. Moreover, it is possible to model how the average UK adult should take decisions on protection to maximise his utility. Different situations will call for different values of risk-aversion, which may explain why economists have come up with differing estimates of this parameter in the past. However, a central, average risk-aversion may be calculated for the average UK adult as 0.85, which is within 4% of the value, 0.82, found from the newly reported method based on a trade-off between income and future free time, and is consistent with several recent economic estimates. Worked examples assess how much an organisation should spend on a protection scheme to prevent accidents with very large environmental consequences.  相似文献

以碳捕集与封存为典型的新兴技术在应对气候变化上的降碳功能显著,但该技术颇具不确定性。“决策于未知”成为政府规制技术风险的真实写照,如何在鼓励碳捕集与封存技术发展,助力“双碳”目标实现的同时,应对随之而来的风险挑战与安全诉求,既是国家必须肩负的义务,也是回应公众期待的内在要求。应运而生的风险预防原则作为应对气候变化的重要举措,为技术风险规制提供了合法性与正当性基础,对于碳捕获、封存技术发展与碳中和目标实现具有重要现实意义。为此,风险预防原则在技术规制中,应当整体遵循弱风险预防理念,彰显秩序、正义和效率的多元价值诉求,实现科学理性与社会理性的平衡。在此基础上,通过多手段的综合应用,开放的风险决策结构,强化风险管理的动态调试,以预防性环境行政公益诉讼为保障,将风险预防原则融汇于碳捕集与封存技术风险规制中。  相似文献

Knowledge creation and reliable decision-making in complex emergencies   总被引:1,自引:0,他引:1  
Kruke BI  Olsen OE 《Disasters》2012,36(2):212-232
This paper examines how the creation of knowledge and the location of decision-making authority within relief organisations influence coordination. Information was collected from the headquarters of international non-governmental organisations in 2003, as well as from Darfur and Khartoum, Sudan, in 2005 and 2007, respectively. Relief organisations rely on quality information dissemination between the field and headquarters. Yet, reporting from the field often is overloaded with misplaced precision, making it difficult for managers at headquarters to grasp the key issues. A high turnover rate among international field officers and a lack of inclusion of local staff and partners prevent the development of accumulated knowledge. Furthermore, most relief organisations have a centralised decision-making system. The creation of 'collective-meaning structures', based on reliable information on all decision-making levels, opens the way to the decentralisation of decision-making to field officers engaged with inter-organisational coordination structures. In sum, more efficient and reliable coordination between organisations relies on improved decision-making systems within each organisation.  相似文献
