摘要:

An Ecological Footprint is defined as the area of land needed to produce the natural resources a population consumes and to assimilate the waste that population produces. By providing a link between consumption and lifestyle and available ecological space, the Ecological Footprint illustrates the concepts of carrying capacity and sustainability. This article presents the results of a detailed study of Australia. The results indicate the Ecological Footprint of the average Australian is approximately 6 hectares per capita. This is more than 4 times the globally available ‘fair share’, placing Australia among the top five consuming nations in the world. This result highlights the unsustainable global nature of the Australian lifestyle, particularly the level of consumption of energy and animal products, with large inequities between Western countries such as Australia, and developing countries.

摘要:

Landcare is essentially a system of volunteer organisations that is loosely coordinated at state and regional levels. The apparent success of Landcare has seen groups become an important delivery mechanism for the Natural Heritage Trust and other initiatives. In this article the author draws upon research in Victoria to argue that we are approaching the limits of what can realistically be expected of Landcare groups. Data were derived from state-wide surveys of Victorian groups between 1991 and 1998 and three 1999 regional case-studies in Corangamite, Glenelg and Goulburn/Broken. Survey data highlighted the extent most groups were operating at historically high activity levels and established a significant positive relationship between activity and government funding. Landcare work takes time and energy, particularly for group leaders, and given existing commitments to work, family and other volunteer organisations, it seems unlikely that current activity levels are sustainable. Survey data highlighted important program management issues that must be addressed as part of a more coherent and determined approach to supporting Landcare.

摘要:

Significant commercial and recreational activities rely on Australia's freshwater fisheries resource. This resource has severely declined in recent years with even the survival of several fish species being threatened. There is currently little coordination of Australia s freshwater fisheries management and research is dominated by perceptions in individual States or Territories. Water and land management agencies, other than those with specific responsibility for fisheries, influence the major issues impacting the sustainability of freshwater fisheries. This article identifies and prioritises the six major threats to the sustainability of Australia's freshwater fisheries resource, based on information gathered from one survey and two expert panels, and suggests research needed to address those threats. The major threats are (1) habitat degradation, (2) pollution, (3) reduced environmental flows, (4) barriers to migration, (5) introduced species and (6) fishing. The commonality of research needs between these six threats and within components of each major threat is stressed. Greater coordination of fisheries, water and land management agencies both between and within States and Territories is required.

摘要:

The generation of company environmental reports has increased significantly in recent years, and this trend appears likely to continue. Clearly one of the aims of environmental reporting is to influence how stakeholders perceive the environmental performance of organizations. It is therefore timely to examine the influence that environmental reports can have on community perceptions of risk.

摘要:

Benefit Cost Analysis has the potential to aid decision-makers searching for an allocation of wetland resources that is optimal for society. However, for Benefit Cost Analysis to be useful, it must be feasible for the most significant benefits and costs of alternative wetland use policies to be estimated in monetary terms. For environmental benefits and costs that are non-marketed, this requirement presents numerous challenges. Choice Modelling shows particular promise in meeting these challenges. A case study involving the rehabilitation of the Macquarie Marshes in central western New South Wales is used to demonstrate how Choice Modelling can generate implicit prices for the individual attributes of wetland rehabilitation projects as well as estimates of the environmental benefits that will be created.
