In Europe, biodiversity conservation relies on the Natura 2000 network. However, it is often difficult to ensure the favourable conservation status of species and habitats due to scarce financial resources. Therefore, we examined the current management strategies and conditions of three Italian Natura 2000 sites based on a questionnaire and stakeholder meetings. Additionally, we qualitatively assessed the potential of ecosystem services provision. Then an A'WOT analysis was carried out to identify and highlight internal and external factors affecting natural and semi-natural ecosystems and the socio-economic context, aiming to propose new instruments and approaches for effective management. The analysis revealed opportunities for developing tourism and the high potential of regulating services, whereas the bureaucratic burden and a lack of funding threaten the attainment of biodiversity conservation goals. Thus, we propose that payments for ecosystem services should be considered to support the effective management of Natura 2000 sites.  相似文献

Gary Francione is an abolitionist: he maintains that we ought to abolish the institutions and practices that support the exploitation of animals. He also believes that veganism is the “moral baseline”—that is, he thinks it’s morally required of nearly everyone in the developed world, and many beyond it. Luis Cordeiro-Rodrigues claims that abolitionism is guilty of racism, albeit “racism without racists.” I contend that his arguments for this conclusion aren’t successful.  相似文献

Differing views of the state and varying ideological postures in the United States and Europe place ??invisible and clandestine?? obstacles against the smooth functioning of transatlantic treaties, agreements, and cooperation in general. These differing views and postures must be rendered visible and acknowledged if efforts to perpetuate a cross-Atlantic dialog are to be viable and stable. Neither the advantages of sharing technology nor common economic and political interests will alone adequately ground cooperation. Sociologists in particular are aware of the ways in which indigenous values and beliefs frequently endure, despite the homogenizing structural change that accompanies industrialization, urbanization, and globalization, and cause misperceptions and misunderstandings.  相似文献

This paper considers the stability of public responses to an urban river restoration scheme on the River Skerne, Darlington, UK, by comparing the results from surveys of local residents carried out before and after scheme implementation. This case study provides evidence of strong and generally consistent positive responses to the proposals and implemented scheme to return the straightened and channelized river to a more natural condition although support was more qualified after than before implementation. Although the scheme design and construction costs were high, nearly two-thirds regarded the scheme as value for money. Exploratory contingent valuation results on whether or not local residents were prepared to pay for the scheme were broadly stable over the two surveys.  相似文献

Stakeholder analysis means many things to different people. Various methods and approaches have been developed in different fields for different purposes, leading to confusion over the concept and practice of stakeholder analysis. This paper asks how and why stakeholder analysis should be conducted for participatory natural resource management research. This is achieved by reviewing the development of stakeholder analysis in business management, development and natural resource management. The normative and instrumental theoretical basis for stakeholder analysis is discussed, and a stakeholder analysis typology is proposed. This consists of methods for: i) identifying stakeholders; ii) differentiating between and categorising stakeholders; and iii) investigating relationships between stakeholders. The range of methods that can be used to carry out each type of analysis is reviewed. These methods and approaches are then illustrated through a series of case studies funded through the Rural Economy and Land Use (RELU) programme. These case studies show the wide range of participatory and non-participatory methods that can be used, and discuss some of the challenges and limitations of existing methods for stakeholder analysis. The case studies also propose new tools and combinations of methods that can more effectively identify and categorise stakeholders and help understand their inter-relationships.  相似文献

Mayer and Frantz (2004) proposed that their connectedness to nature scale (CNS) provides a measure of people's emotional connection to nature. After reanalyzing data from their article, collecting and analyzing our own data, and conducting a content analysis of CNS scale items, we conclude that the CNS does not measure an emotional connection to nature. Although results from our Study 1 and Study 2 support Mayer and Frantz's conclusion that the CNS measures one predominant factor, we suggest that factor measures cognitive beliefs and not emotional connections. Results from our Studies 3 and 4 suggest that the self-referential, less negatively toned wording of CNS items may account for differences in correlations, between the CNS and environmentalism (a measure of environmental identity) and between the New Ecological Paradigm Scale (a measure of environmental beliefs) and environmentalism, reported by Mayer and Frantz. In Study 5, we suggest that correlation differences reported by Mayer and Frantz may also be attributable to method variance, as opposed to content differences between the CNS and the New Ecological Paradigm scale. We provide recommendations for revising the CNS to focus on beliefs about their connection to nature.  相似文献

Abstract

Electric vehicles (EVs) are currently being discussed as a promising means to increase the energy efficiency and sustainability of today's transport systems. While technological progress and cost reduction are certainly crucial topics for their successful diffusion, consumer acceptance is another issue that warrants further analysis. Based on a large online survey (N?=?969), we compared four consumer groups which differ in their likelihood to purchase an EV with regard to their socio-demographic characteristics, their willingness to pay (WTP) and their perceptions of EVs. The findings indicate that early users in Germany are most likely to be middle-aged men living with their families in a multi-vehicle household who have a higher WTP for an EV. Perceived compatibility of an EV with personal needs seems to be the most influential factor on the stated willingness to purchase an EV. With regard to the promotion of EVs, strengthening their environmental advantages and providing financial incentives for purchase are rated as important measures by a majority of the sample, while performance characteristics which are comparable to conventional vehicles seem to be less important for most participants. Based on the data analyses, we provide recommendations for measures regarding the further development and promotion of EVs.  相似文献

The choice of survey mode in contingent valuation research has long been debated in the literature. However, there is limited evidence as to how mode impacts behavior. Using an identical survey administered with telephone, mail, and in-person interviews, this is the first research to examine mode effects using all three commonly employed modes in contingent valuation research. Results show that there is some evidence of social desirability bias in the telephone survey. In addition, the role of income in the decision-making process is an important consideration.  相似文献

Ben Mepham has proposed that a ``matrix' beused in the analysis of ethical problems in foodproduction and elsewhere. In particular cases, thismatrix would ideally cross the most important moralprinciples involved, and the individuals and groupsaffected by the decisions. In the following, Mepham'smodel is assessed in the case of geneticallyengineered bovine growth hormone. My argument is thata more straightforwardly ``consequentialist' analysiscan draw attention to the problems of using thehormone better than Mepham's original proposal. It ispossible, however, that some nuances will be lost inthe process. I do not, therefore, argue for theoverall superiority of my suggestion – it is merelya slightly different, and perhaps sometimes a morepromising, way to analyze the ethical dimensions offood production and marketing.  相似文献

Nepal's geographical landscape of plains, hills, and mountains exposes it to severe climatic conditions. Out of the three regions, the plain, also called Terai, has the greatest risk of flooding, especially during the monsoon season when heavy precipitation coincides with snow and glacier melting from the mountains and hills. In recent years, greater water availability has increased the frequency of flooding, destroying farms, livestock, and infrastructure, hence, reducing agricultural productivity and disrupting economic activities. What makes Nepal a unique case study for climate change is its richness in water resources, propensity to flood, the percentage of poor people living in the flood prone region, and their dependency on natural resources. The lessons drawn can help when formulating pro-poor adaptation policies for other Asian and many developing countries that are as diverse, poor, and agrarian as Nepal. Using data collected through survey interviews, the study examines the ability of the poor to adapt to climate change. The study also explores the adaptive capacity of communities in the Koshi Tappu area, by examining whether or not they have the required capital assets (human, social, natural, physical, and financial capital) to remain resilient in the face of continuous climate events impacts.  相似文献

Hancock, Gregory S., Jonathan W. Holley, and Randolph M. Chambers, 2010. A Field-Based Evaluation of Wet Retention Ponds: How Effective Are Ponds at Water Quantity Control? Journal of the American Water Resources Association (JAWRA) 46(6):1145–1158. DOI: 10.1111/j.1752-1688.2010.00481.x Abstract: Wet retention ponds are widely used structural stormwater best management practices (BMPs) with the primary goals of reducing peak flows and extending flow duration. Despite widespread use, few field-based studies have evaluated the success of wet retention ponds at meeting these goals. We determined pond elevation, flow rate, and pond volume over four years in five suburban watersheds in James City County, Virginia. We selected five ponds designed under regulations requiring a 24 hour inflow-to-outflow centroid lag time for a one year, 24 hour design storm. We used pressure transducers to measure pond water surface elevation at 5 min intervals, and calculated pond outflow and volume using rating curves obtained from site stormwater management plans (SWMPs). Peak inflows, peak outflows, and runoff ratios frequently exceeded SWMP calculations in measured events. Four ponds never achieved the required 24 hour inflow-to-outflow centroid lag for storms similar to the one year, 24 hour storm. These BMPs fail to achieve regulatory goals for channel protection because of regulatory loopholes, underprediction of rainfall intensity, unrealistic predictions of postdevelopment flows in SWMPs, and the inability of wet retention ponds to reduce overall runoff volume. While specific to one locality, the shortcomings highlighted suggest similar field-based assessments of retention pond performance are needed in other locations.  相似文献

The Water Framework Directive (WFD) calls for various modes of public. These participation and involvement. These are judged as key factors to support the successful implementation in terms of attaining a good water status. This paper aims to explore the role of the 'active involvement' of stakeholders for the effective implementation of the WFD regarding the specific problem of reducing agricultural nitrate pollution of groundwater. Our case of reference is the Hase river catchment in northwest Germany, which is a paradigmatic example of an intensive livestock farming region with high nitrate intakes in groundwater. Emphasis is placed on the various forms of involvement that have recently been or will soon be established in northwest Germany at different spatial and administrative scales. We argue that although the WFD refers to whole river basins as the central unit of governance, it is particularly the regional and local scales that will strongly influence the implementation process. We identify different influencing factors and scenario paths, demonstrating both the uncertainties at stake and the range of possible effects that different outcomes of participatory processes will have. These, in turn, are closely linked to the interests, perceptions and strengths of different actors. Identification of critical paths and decision points enables corridors to be mapped out regarding the anticipated success or failure of regional public participation to reduce diffuse agricultural groundwater pollution.  相似文献

ABSTRACT

Across the Global South, community-based adaptation (CBA) projects are increasingly being implemented in an effort to respond effectively and sustainably to the impacts of climate change, with a particular focus on people’s livelihoods. Despite an increase in the number of CBA projects being implemented, detailed analysis and evaluation of their efficacy and the barriers faced in achieving successful outcomes is lacking. This study draws on an analysis of grey literature (i.e. project and donor reports) to explore the barriers faced in achieving effective CBA. An extensive global search of online project evaluations yielded 25 documents comprising 69 projects from which this analysis is based. This paper first presents an overview of the 69 projects and highlights any trends. Second, this paper describes the barriers to CBA according to three broad themes: socio-political, resource, and physical systems and processes. Following this is a discussion of the most prevalent barriers: cognitive and behavioural, financial, and human resources. Third, this paper discusses the key findings elucidated from this review. This includes the need for greater sharing of project reports and findings so lessons can be learned across spatial and temporal scales, and the disparity between critical academic literature on CBA and what is implemented in practice.  相似文献

Sustainable development and eco-efficiency are urgent and imperative demands for the well-being of our planet, continued growth of a society, and human development. Traditional Portland cement production seems unsustainable due to consumption of huge natural resources and energy and significant CO2 emissions. The volume of industrial wastes is increasing significantly, leading to a number of economical and ecological problems. Although industrial wastes can be incorporated in cementitious materials by various traditional methods, the substitution ratio of industrial wastes in cementitious materials is relatively low to avoid unacceptable performance loss. Novel methods, such as improving hydraulic activities of metallurgical slags by adding composition adjusting material at high temperature, improving surface cementitious properties of fly ashes by dehydration and rehydration treatment, and arranging cement clinker and industrial wastes in the particle size distribution of blended cements according to their hydraulic activities, are reviewed. These methods provide more effective approach to prepare high performance blended cements with larger amount of industrial wastes, leading to a very significant role in CO2 emissions reducing, resources and energy conservation of the cement industry.  相似文献

Wild game management for hunting in Western society has become increasingly complex as stakeholders have multiplied and as ‘sustainability’ influences the contemporary debate. This paper questions whether the current legal framework for game management, which has evolved from early European civilisations to focus on ‘hunting rights’, is relevant to regulate the contemporary environmental, social and economic dimensions of wild game and their management. Employing a narrative analysis to focus on deer, the study identifies key legislative tenets and highlights the pertinence of historical laws to contemporary conflicts. The analysis suggests that current legislation is increasingly divergent from contemporary trends and has created inertia with respect to sustainable deer management. The paper offers four options to redress this: state intervention; voluntary collaboration; financial incentives; and establishing a legal responsibility for management. It is concluded that significant innovation is required in one or more of these four areas to facilitate the contemporary sustainable management of wild deer in Britain.  相似文献

Across sub-Saharan Africa, the presence of foreign large-scale mining companies is increasing. This is in part a result of depleting resources in countries such as Canada, United States and Australia, and in part from a more favorable national mine investment climate in several mineral-rich African countries. Their increased presence raises important questions around the potential role and function of Corporate Social Responsibility (CSR) in the sector. In post-conflict and/or fragile states, CSR has further implications for conflict and risk mitigation strategies to ensure the protection of human rights. One CSR approach increasingly being considered is the public–private partnership, whereby companies, public donors, and development agencies leverage their relationships for mutual benefit. There is merit in exploring its function in post-conflict fragile states, where socio-economic needs are high and the capacity of the state to respond to a variety of mine governance challenges is limited. Two case studies from the Democratic Republic of Congo (DRC) are presented, and their policy implications, discussed.  相似文献

This paper derives the optimal level of restorative efforts required to restore environments degraded by invasive species invasion. Specific attention is focused on a case when restoration faces the risk of failure through relapse of the restored environment caused by repeat invasions. The level of restored environment may also play a role in its future improvement or susceptibility to failure. The tradeoff between the optimal level of environmental quality and number of restorative efforts required to attain that given environmental quality is highlighted.  相似文献
