The recent growth of interest in sustainable development has led to the incorporation of the concept into policy making at a variety of scales. In all cases particular emphasis is placed upon the local scale as the focus for the implementation of policy and initiatives and especially upon local authorities as the major contributor to this process. There has been little assessment, however, of the extent to which local authorities either can, or are, undertaking such initiatives. This paper examines: the potential role that local authorities can play in integrating economic development and the environment; the forms of response and initiatives that are currently in place, drawing upon survey evidence from urban local authorities in England and Wales; and some of the limits to local authority action. 相似文献

Though the restoration of disturbed ecosystems has so far played a relatively modest role in the effort to conserve biological diversity, there are reasons to suspect that its role will increase and that its contribution to the maintenance of diversity will ultimately prove crucial as techniques are further refined and as pristine areas for preservation become scarcer and more expensive.It is now possible to restore a number of North American communities with some confidence. However, it should be noted that many current efforts to return degraded lands to productive use, like attempts to reclaim land disturbed by mining, try only for rehabilitation to a socially acceptable condition and fall considerably short of actually restoring a native ecological community.Possible uses for restoration in the conservation of biodiversity include not only the creation of habitat on derelict sites, but also techniques for enlarging and redesigning existing reserves. Restoration may even make it possible to move reserves entirely in response to long-term events, such as changes in climate. Restoration in the form of reintroduction of single species to preexisting or restored habitat is also a critical link in programs to conserve species ex situ in the expectation of eventually returning them to the wild. And restoration provides opportunities to increase diversity through activities as diverse as management of utility corridors, transportation rights-of-way, and parks. 相似文献

Since the initial development of the Ecological Footprint in the early 1990s, the concept has gained increased interest amongst academics and practitioners internationally. In the UK, it is estimated that some 60 to 70 Ecological Footprint studies were undertaken between 1999 and 2004. Although the majority of interest in Ecological Footprinting has come from local government, a recent study has found that government officers involved in the formulation of council policy have not been able to engage with the Ecological Footprint as a process or use the results to inform policy decisions. This paper analyses how an Ecological Footprint has been developed for Cardiff, the capital city of Wales. The approach used to construct an Ecological Footprint for Cardiff has been significantly different to that which had been used previously in the UK, as it has involved a unique consortium of researchers at Cardiff University and policy development officers at Cardiff Council checking the quality of data used in the Footprint calculation, and developing a range of policy scenarios. 相似文献

Increasingly government agencies are seeking to quantify the outcomes of proposed policy options in terms of ecosystem service
benefits, yet conflicting definitions and ad hoc approaches to measuring ecosystem services have created confusion regarding
how to rigorously link ecological change to changes in human well-being. Here, we describe a step-by-step framework for producing
ecological models and metrics that can effectively serve an economic-benefits assessment of a proposed change in policy or
management. A focus of the framework is developing comparable units of ecosystem goods and services to support decision-making,
even if outcomes cannot be monetized. Because the challenges to translating ecological changes to outcomes appropriate for
economic analyses are many, we discuss examples that demonstrate practical methods and approaches to overcoming data limitations.
The numerous difficult decisions that government agencies must make to fairly use and allocate natural resources provides
ample opportunity for interdisciplinary teams of natural and social scientists to improve methods for quantifying changes
in ecosystem services and their effects on human well-being. This framework is offered with the intent of promoting the success
of such teams as they support managers in evaluating the equivalency of ecosystem service offsets and trades, establishing
restoration and preservation priorities, and more generally, in developing environmental policy that effectively balances
multiple perspectives. 相似文献

Air quality management (AQM) is a process of environmental control that must be embedded within a wide range of policy areas, from local-scale initiatives to international treaties, if it is to be successful. Because of the integrative aspects of AQM, it is imperative that joint working is undertaken within local authorities and other involved parties. Environmental health departments have taken the lead role in AQM as they have traditionally had responsibilities for some other aspects of pollution control. However, AQM requires input from a variety of professionals such as transport planners, land-use planners, economic development officers and Local Agenda 21 (LA21) officers, as well as environmental health professionals. This paper examines the involvement of these professions within the AQM process. Results are presented from a widespread questionnaire survey of urban local authorities in England. In the case of air quality, it is concluded that co-operation between the necessary professions is still at an early stage. Transport planners are more fully engaged with the process than are land-use planners or economic development officers. In order that the joint working process develops appropriately, it is suggested that LA21 officers have an important role in facilitating inter-professional working to support the AQM process. 相似文献

The Great Western Development Strategy (GWDS) is a long term national campaign aimed at boosting development of the western
area of China and narrowing the economic gap between the western and the eastern parts of China. The Strategic Environmental
Assessment (SEA) procedure was employed to assess the environmental challenges brought about by the western development plans.
These plans include five key developmental domains (KDDs): water resource exploitation and use, land utilization, energy generation,
tourism development, and ecological restoration and conservation. A combination of methods involving matrix assessment, incorporation
of expert judgment and trend analysis was employed to analyze and predict the environmental impacts upon eight selected environmental
indicators: water resource availability, soil erosion, soil salinization, forest destruction, land desertification, biological
diversity, water quality and air quality. Based on the overall results of the assessment, countermeasures for environmental
challenges that emerged were raised as key recommendations to ensure ecological security during the implementation of the
GWDS. This paper is intended to introduce a consensus-based process for evaluating the complex, long term pressures on the
ecological security of large areas, such as western China, that focuses on the use of combined methods applied at the strategic
level. 相似文献

This article examines the role of economic development agencies in strengthening the environmental performance of industry within rapidly industrialising East Asian economies. Three case-study examples are considered, namely, the role of the Industrial Development Board in reducing industrial pollution in Taiwan, pollution control in the palm oil industry in Malaysia, and the role of the Economic Development Board in influencing environmental performance of industry in Singapore. The concept of embedded autonomy is developed to consider the ways in which agencies of economic development can work with firms and industries while simultaneously remaining autonomous from these firms with respect to setting and enforcing performance standards. The three cases suggest that a form of policy integration that more directly integrates economic and environmental goals within agencies of economic development may be feasible, but only where there exists a strong autonomous government bureaucracy and where there is strong societal commitment to improving the environmental performance of industry. 相似文献

In this article, we critically reflect on the concept of biomimicry. On the basis of an analysis of the concept of biomimicry in the literature and its philosophical origin, we distinguish between a strong and a weaker concept of biomimicry. The strength of the strong concept of biomimicry is that nature is seen as a measure by which to judge the ethical rightness of our technological innovations, but its weakness is found in questionable presuppositions. These presuppositions are addressed by the weaker concept of biomimicry, but at the price that it is no longer possible to distinguish between exploitative and ecological types of technological innovations. We compare both concepts of biomimicry by critically reflecting on four dimensions of the concept of biomimicry: mimesis, technology, nature, and ethics. 相似文献

Predicted climate warming is expected to have profound effects on bark beetle population dynamics in the southwestern United
States. Temperature-mediated effects may include increases in developmental rates, generations per year, and changes in habitat
suitability. As a result, the impacts of Dendroctonus frontalis and Dendroctonus mexicanus on forest resources are likely subject to amplification. To assess the implications of such change, we evaluated the generations
per year of these species under three climate scenarios using a degree-day development model. We also assessed economic impacts
of increased beetle outbreaks in terms of the costs of application of preventative silvicultural treatments and potential
economic revenues forgone. Across the southwestern USA, the potential number of beetle generations per year ranged from 1–3+ under
historical climate, an increase of 2–4+ under the minimal warming scenario and 3–5+ under the greatest warming scenario. Economic
benefits of applying basal area reduction treatments to reduce forest susceptibility to beetle outbreaks ranged from 7.75/ha (NM) to7.75/ha
(NM) to 95.69/ha (AZ) under historical conditions, and 47.96/ha (NM) to47.96/ha (NM) to 174.58/ha (AZ) under simulated severe drought conditions.
Basal area reduction treatments that reduce forest susceptibility to beetle outbreak result in higher net present values than
no action scenarios. Coupled with other deleterious consequences associated with beetle outbreaks, such as increased wildfires,
the results suggest that forest thinning treatments play a useful role in a period of climate warming. 相似文献

Iron Ore Industry Emissions as a Potential Ecological Risk Factor for Tropical Coastal Vegetation 总被引:1,自引:0,他引:1
In the coastal zone of the Espírito Santo state, Brazil, fragments of restinga, which form a natural ecosystem, share their space with an increasing number of iron ore industries. The iron ore dust and SO(2) originating from the industry processing activities can interfere with the vegetation of the adjacent ecosystems at various levels. This study was undertaken in order to evaluate the effects of industry emissions on representative members of the restinga flora, by measuring physiological and phenological parameters. Foliar samples of Ipomoea pes caprae, Canavalia rosea, Sophora tomentosa, and Schinus terebinthifolius were collected at three increasing distances from an ore industry (1.0, 5.0, and 15.0 km), and were assessed for their dust deposition, chlorophyll, and Fe content. Phenological monitoring was focused on the formation of shoots, flowers, and fruits and was also performed throughout the course of a year. The results showed that the edaphic characteristics and the mineral constitutions of the plants were affected by industry emissions. In addition, the chlorophyll content of the four species increased with proximity to the industry. Phenological data revealed that the reproductive effort, as measured by fruit production, was affected by emissions and S. tomentosa was the most affected species. The use of an integrative approach that combines biochemical and ecological data indicates that the restinga flora is under stress due to industry emissions, which on a long-term basis may put the ecosystem at risk. 相似文献
