The author examines the reasons behind the current state of the North American metal mining industry. Taking demand-side factors first, he explains the dramatic fall in metals consumption. External shocks are seen to have affected the previously well rationalized structure of supply in the 1960s, bringing about an increase in production costs and limiting capacity for industrial rationalization. At the beginning of the 1980s, the situation is seen to have been exacerbated by a larger number of producers, more supply sources and an increase in costs. During the course of the decade, the author relates how the situation worsened due to the strength of the US dollar and high interest rates. 相似文献

Research into global environmental change in the United Kingdom, has sought to influence public policy. It has also served to refashion the social sciences themselves, forcing them to consider sustainability as a dimension of all social and economic behaviour. This paper describes the way in which the principle of enhanced sustainability might become a point of reference in social science research. It discusses, some of the lessons that have been learned from the Global Environmental Change Programme and then considers the relationship between this work and research on the environment undertaken within the natural sciences.This paper was presented as a keynote delivery at the Global Forum '94 Conference Towards a sustainable Future: Promoting Sustainable Development, Manchester, UK. 相似文献

Summary In the United Kingdom there is no obvious connection between the Department of the Environment and the Home Office, nor indeed with the Department of Social Security. Yet crime rates are rising and social surveys reveal a drop in support for the institutions of governance-moral, legal and political. Other evidence clearly shows that the income and security of the very poor are declining in relation to the better off. There may well be a link between environmental deprivation, poverty and social alienation. This is not an area where heretofore any British Government has noticeably directed its energies. The UK response to the Rio Agenda 21 contains a proposal to create a Citizens' Environmental Initiative, designed ostensibly to bring sustainability to the grass roots. It now appears that this is to be a largely cosmetic exercise of grant aid to worthy local causes. It does not appear to have addressed significantly the opportunity of linking environmental and social agendas via the medium of locally promoted sustainable development. Yet the divergence efficiency and equality of treatment lies at the heart of the contemporary environmental debate. Proposals to price resource depletion and polluting emissions penalize the poor in the name of environmental efficiency. Unless there is an explicit intertwining of efficiency and equity doctrines, the cause of sustainability is doomed to self-inflicted defeat. Ecological taxation offers a solution, so long as the proceeds promote the cause of social as well as environmental justice.The address was delivered at the Global Forum '94 Academic Conference Towards a Sustainable Future: Promoting Sustainable Development Manchester UK (Fig. 1). 相似文献

A watershed management framework for mountain areas is based on lessons learned from watershed management experience, social and institutional learning, and the use of a watershed management program evaluation in Nepal. The lessons led to the adoption of a subwatershed-based ecosystem approach based on local participation at the subwatershed level. An integrated watershed management framework (IWMF) consisting of eight steps with three checklists was developed focusing on improvement-oriented adaptive management. The eight steps lead to the preparation of a watershed management plan. In the process three checklists are used. While the first checklist has general questions pertaining to watershed analysis, the second allows participation analysis of stakeholders in terms of their strengths, weaknesses, opportunities and threats and opens up new prospects for further reinforcing or building new user group institutions based on consensus. The final checklist consists of hierarchical watershed management objectives, including goals, results and activities leading to a program planning matrix. The framework was applied to watershed planning in the Chure Region to compare the framework-based planning with conventional planning procedures. A significant difference in quality and substance of the output, with and without the use of the framework, suggests that an integrated framework is a useful tool for an ecosystem-based approach to natural resource management and socio-technical conservation. 相似文献

A fundamental purpose of intergovernmental growth management has been to infuse regional concerns—especially regional environmental and economic development concerns—into local land use planning. This paper presents results from a study of state-mandated local planning in coastal North Carolina during the mid-1990s, addressing in particular local efforts to ‘strike a balance’ between environment and economy as required by the state's planning mandate. While acknowledging the need for coastal resource protection, coastal localities were not striking a balance between environment and economy through their planning efforts beyond stating support for the State's minimum resource protection rules. Within this context, key factors yielding less environmentally focused local planning included both local elected officials' concerns about the need for economic development for jobs and their belief that environmental protection was not a local problem. Factors that tended to shift local planning back toward environmental protection included local officials' perception that the local economy was in good shape and heightened citizen engagement. 相似文献

The paper explores the relations of (1) regionalized climate change impulses; (2) their impacts on regional industry sectors; and (3) a regional econometric impact analysis. It develops a methodology by which the impulses of a regional climate change scenario can be transformed into ‘primary’ impacts on the capital stock and value added of climate-sensitive regional industries. These industries are vulnerable to ‘creeping’, i.e. continuous, climate change impulses, and they tend to react through ‘defensive’ investment. In addition, a singular flooding event is simulated for a specific local area and its different capital stocks. The stock damages and value-added losses of both the continuous industrial impacts and the singular flooding are inserted into a regional econometric model. This is sectorally disaggregated in stock, value-added and investment functions. It is also calibrated in the very-long run (through to the year 2040), according to different scenarios. The regional economic ‘secondary’ effects on the regional GNP are calculated. In addition to the calculation of regional economic primary and secondary impacts, the methodological issue of generating more transparency of the causal chains by use of damage functions, reaction functions, and comparative defensive strategies are discussed. 相似文献

Cyst-like masses in the neck and back region, simulating an encephalocele, were detected by midtrimester ultrasound examinations in two sib fetuses. After termination, the fetuses were found to have large cystic hygromas. The present observation strongly suggests the existence of an autosomal recessive type of cystic hygroma. 相似文献

Before termination of pregnancy, four techniques for retrieving fetal cells transcervically were investigated: uterine lavage, endocervical lavage, cytobrush and mucus aspiration. The yield of fetal cells in these samples was studied and found to be somewhat better after uterine lavage. A preliminary assessment of the safety of mucus aspiration was carried out before transcervical chorionic villus sampling (CVS) in continuing pregnancies. No difference in outcome to a control group having only CVS was found. 相似文献
