Sheep's wool insulation: A sustainable alternative use for a renewable resource?

Material selection in manufacturing may be characterized as a series of trade-offs between characteristics, properties, environmental impacts, sustainability, availability, and economics. Societal concerns about the environmental impacts of construction practices and materials have been expressed through an increase in the demand, production and use of “green” building products. This, combined with a desire to integrate more bioproducts and natural and renewable resources into the construction industry, has extended to the production and promotion of insulation made from sheep's wool.Although substantial literature exists on the insulation properties and other benefits of wool, less is known about the economics and manufacturing processes of sheep's wool insulation at varying scales of production. This paper contributes to this field of enquiry through presentation of the preliminary results of a wool insulation manufacturing pilot project, in which the scale and economics of the production of sheep's wool insulation were considered. Processing techniques, the impact of sheep breed, yield, energy use, and manufacturing costs were also examined. The results of the pilot project indicate that, while sheep's wool insulation produced at a smaller, or artisanal scale shows some potential, scale of operation and volume of production need to be carefully considered in order to ensure long-term sustainability of the operation. Using the least expensive sheep's wool available for the manufacture of wool batt insulation (and thereby reducing production costs) did not, in this pilot study, have a negative impact on productivity or product performance. Diversion of this waste stream of currently less marketable, and consequently less valuable wool, into the production of a green building material may offer small but significant benefit to sheep producers and the broader agricultural community, as well as consumers.     

公民环境信访行为影响因素的实证分析——基于规范激活理论

环境信访是中国公民环境利益表达的重要途径,也是其参与环境治理的重要通道,引导公民有序进行环境信访对于加强生态文明建设、深化环境治理、维护社会稳定具有重要意义。本研究从环境信访的参与主体——公民入手,基于社会心理学中规范激活理论的连续模型,构建了公民环境信访影响因素的理论模型,并运用AMOS 20.0对S市9个行政区500位市民的问卷调研结果进行实证分析,探究公民环境信访行为的社会心理影响因素。研究结果表明:规范激活理论的连续模型能够较好地解释中国公民的环境信访行为,其中环境信访结果认知正向影响环境信访责任归属,公民的个体规范需要通过责任归属得以激活,从而影响公民环境信访行为意向。因此,政府可以通过环保知识的宣传教育和完善环境信访相关法律法规来提升公民环保意识和环境信访责任归属感,同时可以通过环保政策法规的宣传、畅通环境信访渠道以及对公民环境信访行为的有效处理来促进公民对环境信访行为积极意义的认知,从而推动公民有序进行环境信访。     

The impact of economic activity in Asturias on greenhouse gas emissions: consequences for environmental policy within the Kyoto Protocol framework

Climate change is one of the major worldwide environmental concerns. It is especially the case in many developed countries, where the greenhouse gas emissions responsible for this change are mainly concentrated. For the first time, the Kyoto Protocol includes an international agreement for the reduction of the net emissions of these gases. To fulfil this agreement measures designed to reduce or limit current emissions have to be brought into force. Consequently, fears have arisen about possible consequences on competitiveness and future development of manufacturing activities and the need for support mechanisms for the affected sectors is obvious. In this paper, we carry out a study of the emissions of gases responsible for climate change in Asturias (Spain), a region with an important economic presence of sectors with intensive emissions of CO(2), the chief greenhouse gas. To be precise, in the first place, the volumes of direct emissions of the said gases in 1995 were calculated, showing that the sectors most affected by the Kyoto Protocol in Asturias are iron and steel and electricity production. Secondly, input-output analysis was applied to determine the direct and indirect emissions and the direct, indirect and induced emissions of the different production sectors, respectively. The results derived from the direct and indirect emissions analysis and their comparison with the results of the former allow us to reach some conclusions and environmental policy implications.     

Critical analysis of the waste management performance of two uranium production units in Brazil--part II: Caetite production center

This paper discusses the environmental waste management of the Heap-Leach Uranium Production Facility of Caetité located in a semi-arid region in Brazil. A comparison is made with the first uranium production site of the country located in Poços de Caldas. It is demonstrated that differences in the operational process along with different environmental conditions can lead to different impacts. In the present case groundwater is the potential most sensitive environmental medium despite the well-established consensus in the literature that radon and aerosol emissions may turn-out to be the most relevant environmental aspects of an installation located at this type of region. Most of the ²²⁶Ra content in the ore remains in the leached ore that is deposited with the waste rock. A lack in appropriate prediction of the hydrological balance has been causing unanticipated emissions of liquid effluents into the environment. Chemical treatment of this effluent may be needed. Contamination of groundwater in the short term by the waste ponds is not to be expected but it can be a relevant issue in the long term. As a consequence, careful closure schemes will need to be put in place. Finally, the overall costs with remediation in the Caetité production center are lower than those observed at the Poços de Caldas mining site.     

Legislative Approaches to Drought Management

Droughts are a natural scourge with extremely serious socio-economic consequences, leading not only to human suffering and misery, but also to grave environmental deterioration. Some of the impacts of drought may be curbed through technological, economic and legal measures. This paper deals particularly with the last of these.
Legal measures are grouped according to their objectives, such as: the mitigation of drought impacts; the regulation of water use; the control of production and distribution of goods and services; the regulation of the relationship between man and the environment; and the promotion of general socio-economic change.
While developed countries have been able to manage production factors and promote, enact and enforce regulatory legislation, most developing countries face serious restrictions either to managing drought situations or to enforcing any kind of legislation intended to deal either with the impact of drought or with the artificial situations reinforcing these impacts.     

Assessing the environmental performance of English arable and livestock holdings using data from the Farm Accountancy Data Network (FADN)

Agri-environment schemes (AESs) have been implemented across EU member states in an attempt to reconcile agricultural production methods with protection of the environment and maintenance of the countryside. To determine the extent to which such policy objectives are being fulfilled, participating countries are obliged to monitor and evaluate the environmental, agricultural and socio-economic impacts of their AESs. However, few evaluations measure precise environmental outcomes and critically, there are no agreed methodologies to evaluate the benefits of particular agri-environmental measures, or to track the environmental consequences of changing agricultural practices. In response to these issues, the Agri-Environmental Footprint project developed a common methodology for assessing the environmental impact of European AES. The Agri-Environmental Footprint Index (AFI) is a farm-level, adaptable methodology that aggregates measurements of agri-environmental indicators based on Multi-Criteria Analysis (MCA) techniques. The method was developed specifically to allow assessment of differences in the environmental performance of farms according to participation in agri-environment schemes. The AFI methodology is constructed so that high values represent good environmental performance. This paper explores the use of the AFI methodology in combination with Farm Business Survey data collected in England for the Farm Accountancy Data Network (FADN), to test whether its use could be extended for the routine surveillance of environmental performance of farming systems using established data sources. Overall, the aim was to measure the environmental impact of three different types of agriculture (arable, lowland livestock and upland livestock) in England and to identify differences in AFI due to participation in agri-environment schemes. However, because farm size, farmer age, level of education and region are also likely to influence the environmental performance of a holding, these factors were also considered. Application of the methodology revealed that only arable holdings participating in agri-environment schemes had a greater environmental performance, although responses differed between regions. Of the other explanatory variables explored, the key factors determining the environmental performance for lowland livestock holdings were farm size, farmer age and level of education. In contrast, the AFI value of upland livestock holdings differed only between regions. The paper demonstrates that the AFI methodology can be used readily with English FADN data and therefore has the potential to be applied more widely to similar data sources routinely collected across the EU-27 in a standardised manner.     

The importance of local context in the planning of environmental projects: examples from two biogas cases

The planning of facilities to improve the environment is often carried through in the form of locally based construction projects. These projects can be complex, involving a variety of issues and a number of different actors from both the public and private sectors. By drawing on previous research on project planning, an analytical model for analysing the issues connected with the planning and implementation of environmental projects is developed. The main argument of the paper is the importance of considering how context-specific factors affect project design and project management. The empirical material is taken from the planning of two biogas projects in Sweden and it is showed how differences in factors such as the actors involved, the organisational framework and the political setting lead to two markedly distinct planning approaches. The results of the paper, which also highlight the importance of a flexible planning approach, are relevant not only for biogas but also for other projects with similar characteristics.     

Program efficiency analysis within the environmental landscape

The aim of this paper is to demonstrate the importance of accounting for environmental impacts in project feasibility. Cost–benefit analysis, a germane tool for measuring a project’s feasibility, can be utilized for projects with environmental consequences. This paper first provides a background on cost–benefit analysis as well as a background on environmental cost–benefit analysis. It then provides the steps taken in order to perform this type of analysis. With this cost–benefit analysis and environmental cost–benefit analysis framework in mind, six international case studies are reviewed to demonstrate how cost–benefit analysis is applied to various environmental projects around the world using different methods and from both a public and private sector viewpoint. Recommendations are then put forward to address the need for continued consideration and implementation of environmental impacts on cost–benefit analyses.

Traditional olive orchards on sloping land: Sustainability or abandonment?

Traditional olive orchards account for a large share of the area under olives in the EU, particularly in marginal areas, like those analysed in the OLIVERO project. In general, traditional olive growing can be described as a low-intensity production system, associated with old (sometimes very old) trees, grown at a low density, giving small yields and receiving low inputs of labour and materials. Though such systems are environmentally sustainable, their economic viability has become an issue, since EU policies favour more intensive and competitive systems. Orchards that have not been intensified seem to be threatened by the recent reform of the EU olive and olive oil policy, as income support has been decoupled from production. The main purpose of this paper is to identify the present constraints to traditional olive growing, and to recommend some private and public interventions to prevent its abandonment. During the OLIVERO project, traditional olive production systems were identified and described in five target areas (Trás-os-Montes-Portugal, Cordoba and Granada/Jaen-Spain, Basilicata/Salerno-Italy, and West Crete-Greece). The causes and consequences of abandonment are discussed, based on the analysis of the costs and returns, which revealed that these systems are barely economically sustainable. Their viability is only assured if reduced opportunity costs for family labour are accepted, and the olive growing is part-time. Based on these results, recommendations are made to prevent the abandonment of traditional olive growing and to preserve its environmental benefits.     

Off-site consequences: Life after risk management plans,Part I—public response

Many environmental and facility managers view the submittal and public availability of their facilities' risk management plans (RMPs) as discrete events and give little thought about how RMP information may influence their future relations with plant communities and other stakeholders. In fact, the public availability of RMPs will have some significant and lasting consequences that have the potential to alter RMP sources' relations with a wide variety of stakeholders. This article is the first of two installments that will explore some of the likely outcomes of the risk management program, with a particular emphasis on those consequences tied to the public availability of the RMPs themselves. This installment considers likely responses at the community level and from both national and local environmental advocacy groups. The second installment will look at likely responses to RMP information in land use planning, by the financial services sector, by regulatory agencies, and by the senior management of RMP sources' owners and operators. Although the responses of individual communities to RMPs will be governed by a number of variables, including the nature of existing relations with individual RMP sources, proximity (or perceived proximity) of residences or other public and environmental receptors to RMP sources, and stakeholders' attitudes toward chemicals and chemical use, there are certain potential responses that managers should look for in their communities. These RMP-driven responses and expectations are discussed in the first installment of this article.© 1999 John Wiley & Sons, Inc.     

Environmental Impacts of the Use of Ecosystem Services: Case Study of Birdwatching

The main reason for promoting the concept of ecosystem services lies in its potential to contribute to environmental conservation. Highlighting the benefits derived from ecosystems fosters an understanding of humans’ dependence on nature, as users of ecosystem services. However, the act of using ecosystem services may not be environmentally neutral. As with the use of products and services generated within an economy, the use of ecosystem services may lead to unintended environmental consequences throughout the ‘ecosystem services supply chain.’ This article puts forward a framework for analyzing environmental impacts related to the use of ecosystem services, indicating five categories of impact: (1) direct impacts (directly limiting the service’s future availability); and four categories of indirect impacts, i.e., on broader ecosystem structures and processes, which can ultimately also affect the initial service: (2) impacts related to managing ecosystems to maximize the delivery of selected services (affecting ecosystems’ capacity to provide other services); (3) impacts associated with accessing ecosystems to use their services (affecting other ecosystem components); (4) additional consumption of products, infrastructure or services required to use a selected ecosystem service, and their life-cycle environmental impacts; and (5) broader impacts on the society as a whole (environmental awareness of ecosystem service users and other stakeholders). To test the usefulness of this framework, the article uses the case study of birdwatching, which demonstrates all of the above categories of impacts. The article justifies the need for a broader consideration of environmental impacts related to the use of ecosystem services.     

Environmental Monitoring and Audit in Hong Kong

This paper provides an overview of H ong Kong's approach to the environmental monitoring and audit of the construction and operation of major development projects as a continuation of the Environmental Impact Assessment process. The paper examines the development of systems and guidelines for the engineer who is responsible for implementing a project, in terms of environmental monitoring and audit protocols set out in a manual, and in terms of monthly and quarterly reporting. In addition, systems have been developed to manage cumulative effects arising from multiple projects in one area which are undertaken by different agents. The paper concludes with a number of key lessons learned, pointing out what environmental monitoring and audit teams need to do to be successful, and what needs to be done to enhance the effectiveness of environmental monitoring and audit protocols.     

Bioenergy and Land Use: Framing the Ethical Debate

Increasingly, ethical concerns are being raised regarding bioenergy production. However, the ethical issues often do not stand out very clearly. The aim of the present paper is to improve on this situation by analyzing the bioenergy discussion from the perspective of land use. From this perspective, bioenergy production may give rise to ethical problems because it competes with other forms of land use. This may generate ethical problems mainly for two reasons. First, bioenergy production may compete, directly or indirectly, with food production; and as consequence the food security of poor people may be adversely affected (social aspects arguments). Secondly, the production of bioenergy may directly or indirectly lead to deforestation and other changes of land use that have a negative effect on greenhouse gas emissions (environmental arguments). So from this perspective the main challenge raised by bioenergy production is to secure responsible land use. The purpose of the paper is not to advocate, or promote, a specific ethical position on bioenergy, but to structure the main arguments found. The paper falls in two parts. One part addresses social aspects arguments for using agricultural land for bioenergy—where food insecurity, malnourishment, and significant food poverty are the main concerns. The second part scopes environmental implications—notably greenhouse gas emissions impact, as affected by deforestation and other (indirect) land-use changes. Alongside showing some of the current dilemmas presented by wider land-use changes, arguments are analyzed from two ethical angels: a consequentialist and a deontological.     

环境邻避冲突中公众纠纷解决机制的发展与完善

近年来我国环境邻避形势严峻,人民群众日益增长的对美好生态环境的需求、公众参与环境保护的意愿、维护自身权益的意识和当前纠纷解决机制不平衡不充分的矛盾突出。为了有效化解冲突,环境邻避纠纷解决机制先后经历了萌发期、探索期,并逐步进入多元化发展阶段。现阶段环境邻避纠纷非诉讼解决方式存在制度局限,诉讼解决方式在实际应用中面临诉讼积极性不高、立案难、举证难、审理难等问题。为此,结合环境邻避纠纷的特点,本文提出了环境邻避纠纷解决机制完善建议:一是预防为主,建立贯穿项目建设始终的公众参与法律制度体系,增强公众意见反馈的强制性;二是分类化解,建立和完善适应不同需求的纠纷解决程序,加强多元化纠纷解决机制的衔接。希望通过建立"预防为主,分类化解"的精细化纠纷解决机制来推动环境邻避冲突的有序解决。     

Environmental impact assessment: An international evaluation

Experiences with environmental impact assessment (EIA) in a number of countries are discussed in the light of both explicit and implicit goals and objectives. Adequate environmental information is not always available to decision makers because of failure to apply EIA to all relevant decisions, the continuing inadequacies of prediction and evaluation techniques, the failure to consider alternatives adequately, and the bias of some EISs. EIA frequently results in changes to proposals and may result in stricter environmental management conditions in some cases, but some people regard it as a failure because it has not stopped development. Generally, EIA leads to better integration of environmental factors into project planning. Open procedures and freedom of information encourage responsiveness to EIA procedures, which can be weakened by discretionary powers and lack of access to the courts by public interest groups. However, legal standing may have side effects that offset its advantages. EIA can encourage cooperation and coordination between agencies but does not ensure them. Similarly, it can have a limited role in coordinating interstate and international policies. In the long term, the success of EIA depends on adequate monitoring, reassessment, and enforcement over the life of the project. EIA has generally opened up new opportunities for public participation, and may help to reduce conflict. EIA procedures need to be integrated with other environmental protection and development control programs, and various means exist for reducing its cost to developers and the public.     

The Aging of America's Reservoirs: In‐Reservoir and Downstream Physical Changes and Habitat Implications

Reservoirs are important for various purposes including flood control, water supply, power generation, and recreation. The aging of America's reservoirs and progressive loss of water storage capacity resulting from ongoing sedimentation, coupled with increasing societal needs, will cause the social, economic, environmental, and political importance of reservoirs to continually increase. The short‐ and medium‐term (<50 years) environmental consequences of reservoir construction and operation are well known and include an altered flow regime, lost connectivity (longitudinal, floodplain), an altered sediment regime, substrate compositional change, and downstream channel degradation. In general, reservoir‐related changes have had adverse consequences for the natural ecosystem. Longer term (>50 years) environmental changes as reservoirs enter “old” age are less understood. Additional research is needed to help guide the future management of aging reservoir systems and support the difficult decisions that will have to be made. Important research directions include assessment of climate change effects on aging and determination of ecosystem response to ongoing aging and various management actions that may be taken with the intent of minimizing or reversing the physical effects of aging.     

Clashing coalitions: a discourse analysis of an artificial groundwater recharge project in Finland

The purpose of this paper is to increase understanding of the dynamics of knowledge production in the context of large-scale environmental projects causing local conflict. In particular, the paper analyses the discourse coalitions that formed around an artificial groundwater recharge project for the Turku Region in Finland. The material for this study consists of over 400 articles and opinion pieces which were collected from local and regional newspapers between 1999 and 2010. The articles were analysed by using Hajer's [1995. The politics of environmental discourse. Ecological modernisation and the policy process. Oxford, UK: Clarendon] discursive framework, and the analysis was complemented with the concept of knowledge coalition by Van Buuren and Edelenbos [2004. Conflicting knowledge. Why is joint knowledge production such a problem? Science and Public Policy, 31 (4), 289–299]. Results of the study indicate that knowledge coalitions were formed among the researchers, lay residents, and policy-makers, and they all utilised similar expertise-based factual arguments to support their cause. Thus, the paper participates in the academic discussion on the use and interpretation of expert knowledge in environmental policy-making by reshaping the division between experts and lay residents.     

The environmental dimension of national security: A test of systems analysis methods

The systems approach permits us to analyze national security as a cluster of interconnected elements, in which the environmental dimension appears to be the most important one. The environmental problem is divided into two main aspects: environmental security per se and the impact of environment on the overall status of a nation's security. It is argued here that the quality of life and health serve as both the main objective and the principal criterion of environmental security in a social system. Indices of these two factors are used in this article as indicators of the state of this type of security. They confirm that vast areas of Russia, the Ukraine, and Central Asia (especially the Aral Sea region) should be considered as presenting a substantial risk to local people and even producing global impacts on both natural and man-made systems. Environmental factors that destabilize national security are also divided into two groups: those that impact social systems directly and negatively (mainly natural disasters) and technological and sociopolitical agents that cause indirect impacts, in both war and peace time, as well as in the civil and military sectors of the economy. Developments in the former Soviet Union (the Commonwealth of Independent States) are used as an illustration of the consequences that such impacts may have on the status of national security.     

消费价值差对绿色消费行为意向的影响

文章基于文献分析,提出了消费价值差模型,并以此结合量表和结构方程模型来检验消费价值差对消费者绿色商品的消费意向与市场需求的影响。研究结果说明,消费价值差越大,绿色消费行为意向和市场需求程度越低,其中效用价值差与环境价值差的反向影响最大。鉴于上述结论,政府及企业在制定相关政策及设计推广绿色商品时,应重视消费者的认知和情感需求,并针对不同群体开展具有差异性的环保宣教工作。
