The cumulative dimensions of impact in resource regions 总被引:1,自引:0,他引:1
The development of mineral and energy resources worldwide has placed pressure on regional environments, economies and communities. The cumulative impacts, or cumulative effects, arising from overlapping development have stretched political systems that have traditionally been geared toward the regulation and management of individual resource developments, presenting challenges for policy makers, resource developers and civil society actors. An equally challenging task has been realisation of the potential development dividends of mineral and energy resources in the areas of business development, infrastructure, human development or the management of resource revenues. This paper introduces a special issue on ‘Understanding and Managing Cumulative Impacts in Resource Regions’. The special issue interrogates the effectiveness of new and traditional policy responses, explores methods and strategies to better respond to cumulative impacts, and details practical examples of collaborative and coordinated approaches. Papers cover a range of environmental, economic and social issues, geographical regions, commodities, and conceptual approaches. This introductory paper introduces the cumulative impact issues that have manifest in resource regions, critically appraises current conceptions of cumulative impacts, and details management and policy responses to address the cumulative dimensions of impact. 相似文献

It is commonly recognized that there are constraints to successful regional-scale assessment and monitoring of cumulative impacts because of challenges in the selection of coherent and measurable indicators of the effects. It has also been sensibly declared that the connections between components in a region are as important as the state of the elements themselves. These have previously been termed “linked” cumulative impacts/effects. These connections can be difficult to discern because of a complicated set of interactions and unexpected linkages. In this paper we diagnose that a significant cause of these constraints is the selection of indicators without due regard for their inter-relationships in the formulation of the indicator set. The paper examines whether the common “forms of capital”, i.e., natural (renewable and non-renewable), manufactured, social, human and financial capitals, framework is a potential organizing structure. We examine a large region in western NSW Australia where the predominant production systems are mining and grazing for production of wool, beef and lamb. Production in both is driven by consumption of a non-renewable resource, i.e., ore for mining and topsoil for grazing, the latter on the basis that loss rate estimates far exceed soil formation rates. We propose that the challenge of identifying connections of components within and between capital stores can be approached by explicitly separating stores of capital and the flows of capital between stores and between elements within stores, so-called capital fluxes. We attempt to acquire data from public sources for both capital stores and fluxes. The question of whether these data are a sufficient base for regional assessment, with particular reference to connections, is discussed. The well-described challenge of a comparative common currency for stores and fluxes is also discussed. We conclude that the data acquisition is relatively successful for stores and fluxes. A number of linked impacts are identified and discussed. The potential use of money as the common currency for stores and fluxes of capital is considered. The basic proposition is that replacement or preservation costs be used for this. We conclude that the study is sufficiently positive to consider further research in fully-coupled models of capital stores and fluxes. 相似文献
