Political pressures exist to increase the economic efficiency of timber management and production on the national forests
managed by the USDA Forest Service. There is growing belief both outside and within the Forest Service that current levels
of timber production, and most particularly uneconomic timber production, should be reduced. Many argue that eliminating uneconomic
timber management programs will both save money and reduce environmental degradation. This article traces the political evolution
of the focus on economic efficiency in timber production and explores the political-institutional factors that are shaping
the current policy debate. The below-cost issue is less about economic efficiency than it is about political advantage and
alternative political visions of the societal role of the nation's national forests now and in the future. 相似文献

Wildlife resources the world over have long been subject to harvest and management. As wildlife uses have grown, so too have the need and desire to ensure their sustainability.
This new context of sustainability presents opportunities to merge ecological, economic and social elements to foster development. This paper presents the management and harvesting of wild kangaroos as an example of the potentially sustainable use of a natural resource. Some comparisons are drawn between the use of other wild living resources, deer in Europe and crayfish in Western Australia. However, sustainability of kangaroo species and the industry is not just a matter of market economics and ecology, it must also be socially sustainable. The public policy instrument of a statutory advisory board with a marketing function is proposed in order to integrate the cultural and social aspects of kangaroo management with the economic and ecological aspects. Through such integration, full sustainability of a wild resource then might be achieved. 相似文献

This paper examines the relationship between North American beef consumption and deforestation in South and Central America.
Some writers have argued that consumption of hamburgers in North America, particularly hamburgers consumed in fast food restaurants,
contributes to the depletion of the rainforest in South and Central America. We survey the published policy literature on
the causes of rainforest depletion in the region. We also review the published estimates of the rate and extent of clearing
of rainforest that has occurred in South and Central America since 1970. Finally, we review the data on beef imports and consumption
in Canada and the United States in a effort to assess the importance of South and Central America as suppliers of beef to
the North American market. We conclude that the relationship between beef consumption in North America should not be considered
an important cause of forest depletion in South and Central America. Domestic policies and market forces in the countries
where rainforests are located are the leading causes of rainforest depletion in this region. This lesson seems to have been
lost on some popular and even some textbook writers on this subject.

Industry Response to the Challenge of Sustainability: The Case of the Canadian Nonferrous Mining Sector 总被引:3,自引:0,他引:3
Luis E. Sánchez 《Environmental management》1998,22(4):521-531
/ The paper investigates how the Canadian nonferrous sector is tackling the challenge of sustainable development. Although there is no consensus as to what sustainable development means in practice for management in the sector, at least three dimensions must be taken into account: (1) metals are recyclable, the availability of this resource is not a concern for the foreseeable future; (2) the need to minimize environmental impacts of metals exploration, extraction, transformation, consumption, and recycling; and (3) production activities should not be socially or culturally disruptive. The nonferrous mining industry faces several environmental problems. Some of the most significant are acid mine drainage, sulfur emissions, recycling, and metals toxicity. The industry has developed a number of responses to address these specific concerns as well as other more general challenges. Six strategies are described and analyzed: (1) research and development, (2) an effort of consensus building among stakeholders known as the Whitehorse Mining Initiative, (3) international networking, (4) active involvement in the development of environmental management standards, (5) management reorganization and (6) voluntary agreements. The importance of external factors in the shaping of corporate environmental management practices is discussed, in particular the role of government. Progress has been achieved in three areas: (1) managerial practices and organization, (2) reducing the impacts of ongoing operations and (3) minimizing future liabilities, but two significant fields of conflict remain, namely mining in wilderness areas and projects on aboriginal lands.KEY WORDS: Canada; Environmental management; Minerals industry; Nonferrous metals; Sustainable development; Whitehorse Mining Initiative 相似文献

/ The rural West of the United States is considered strongly antienvironment. The traditional economic reliance of the area on natural resources has long explained this antienvironment stance. The region consistently elects federal officials who as a group consistently vote against environmental bills and seek to undo existing federal environmental regulation. These politicians defend their antienvironment actions based on their perception of the economic composition and interests of the region. Recent studies, however, have suggested that rural residents are increasingly concerned about environmental issues. These studies, however, lack a consistent theoretical basis. This article uses an alternative economic typing system to examine the economic composition of rural Idaho and suggests that the results found using the alternative typing system might provide a theoretical basis to explain why some studies are finding increased rural environmental support. The results show that rural Idaho is much more economically diverse using this alternative typing methodology compared to the outcomes of traditional USDA economic methodologies. The policy and research implications of these findings are examined.KEY WORDS: Rural; Environmental policy; Economic composition 相似文献

The paper investigates law compliance in case of on-farm timber extraction in Ghana. It empirically investigates compliance with rules that (i) require timber operators to obtain prior and informed consent from the farmers, (ii) require timber operators to pay appropriate and timely compensation for crop damage caused by timber extraction and (iii) ban chainsaw lumbering. The study documents a low level of compliance in all three domains. Subsequently, the paper discusses the underlying causes for the observed low compliance. The low compliance level is attributed to a legislation, and enforcement, that provides huge financial incentives for non-compliance for both farmers and timber operators, and in the latter case both with and without legal permits. At the same time the regulation is perceived to violate their moral values. The paper underlines the interests of the political elite as decisive in shaping the current regulation and the way it is implemented on the ground. It asserts that eliciting compliance requires consideration of both the instrumental and normative perspectives; else it becomes illusive. The study thus challenges the typical response of governments in developing countries, who, supported by donor agencies, attempt to elicit compliance through enhanced law enforcement efforts. The results presented on the Ghana case suggest that such an approach is unlikely to elicit compliance. 相似文献

This article examines the relationship between increased metal mining and sustainable development in the eastern section of the Amazonian state of Pará in Brazil. Since the early 1980s, mining has grown rapidly in Pará and local mining operations have become global leaders in the production of iron, manganese, bauxite, aluminum, gold, copper and — in the near future — nickel. To stay in tune with global standards, these companies have committed themselves to the principles of sustainability and have obtained certification for both social and environmental aspects of their activities. The article looks into whether such certification is linked to sustainable development of the relatively poor regions where these companies operate. The main findings are that: (1) there is a visible association between certification and improved performance by the companies, but not with the development of nearby areas; and (2) social‐environmental certification processes place more emphasis on ecological variables than on social ones. 相似文献

Info-Gap Decision Theory for Assessing the Management of Catchments for Timber Production and Urban Water Supply 总被引:3,自引:0,他引:3
While previous studies have examined how forest management is influenced by the risk of fire, they rely on probabilistic estimates
of the occurrence and impacts of fire. However, nonprobabilistic approaches are required for assessing the importance of fire
risk when data are poor but risks are appreciable. We explore impacts of fire risk on forest management using as a case study
a water catchment in the Australian Capital Territory (ACT) (southeastern Australia). In this forested area, urban water supply
and timber yields from exotic plantations are potential joint but also competing land uses. Our analyses were stimulated by
extensive wildfires in early 2003 that burned much of the existing exotic pine plantation estate in the water catchment and
the resulting need to explore the relative economic benefits of revegetating the catchment with exotic plantations or native
vegetation. The current mean fire interval in the ACT is approximately 40 years, making the establishment of a pine plantation
economically marginal at a 4% discount rate. However, the relative impact on water yield of revegetation with native species
and pines is very uncertain, as is the risk of fire under climate change. We use info-gap decision theory to account for these
nonprobabilistic sources of uncertainty, demonstrating that the decision that is most robust to uncertainty is highly sensitive
to the cost of native revegetation. If costs of native revegetation are sufficiently small, this option is more robust to
uncertainty than revegetation with a commercial pine plantation. 相似文献

The establishment of forest reserves for the benefit of other resources and other land uses in areas where timber harvesting is taking place constitutes a significant withdrawal of wood fiber annually in Ontario.This article reports on a case study carried out on a representative forest area in northern Ontario where the primary land use is timber extraction. The results projected to the whole province show that the direct cost to the provincial economy of removing these forest lands from timber production is of the order of $2.5 million annually. 相似文献

The European Union (EU) is the world’s largest trading bloc and the most influential supra-national organisation in the region.
The EU has been the goal for many eastern European States, for Croatia accession remains a priority and underpins many of
its national policies. However, entry into the EU requires certain commitments and concessions. In October 2003 the Croatian
parliament declared an ecological and fisheries protection zone in the Adriatic. Under pressure the zone was suspended, finally
entering into force in March 2008 exempting EU States. There are other marine conflicts between Croatia and the EU, particularly
the contested maritime border with Slovenia, and the development of the Croatian fishing fleet in opposition to the Common
Fisheries Policy. Conversely, attempts to harmonise Croatian Nature Protection with the EU Habitats Directive, facilitated
by pre-accession funding, has galvanised conservation policy. Since 2005 two marine protected areas have been declared, significantly
increasing the marine ecosystem under protection. Finally, the development of the Marine Strategy Framework Directive is the
latest EU attempt to integrate environmental policy in the maritime realm. This will have an effect not only on member States
but neighbouring countries. For marine nature protection to be effective in the region the Adriatic Sea needs to be viewed
as a mutually important shared and limited resource not a bargaining chip. Negotiations of the EU and Croatia have been watched
closely by the other Balkan States and precedents set in this case have the potential to affect EU expansion to the East. 相似文献
