In areas where rivers have been altered and regulated through dams, the effect on wetland ecosystems can lead to 'wastage' of the land as natural systems are destroyed. In response to the effects of streamflow regulation on a wetland near the city of Albury, on the Murray River, the development of the Wonga Wetlands and associated site rehabilitation addresses two key issues: wasteland and waste water. A Community Advisory Committee has been actively and directly involved in the project, initiated and implemented by the Albury City Council, to restore an area of original wetland into a community ecological resource that utilises 100% of the domestic, commercial and industrial urban 'waste' water from the city's water treatment plant. This project represents a significant direction in the way communities and local governments approach resource recovery. This paper analyses the Wonga Wetlands project from the perspective of sustainable management of waste in terms of water resources and presents it as a model for community-based environmental application and long-term resource sustainability.  相似文献

The growing popularity of privatized solid waste management service in least developed countries warrants an exploration of factors that are likely to impact on its sustainability. This study takes integrated solid waste management approach by analyzing relevant issues on both market sides. We use a three step theme development sequence to analyze the data obtained on service providers through library research, observations and interviews. This was followed by an opinion survey on the demand side to elicit households’ support for service improvement. Findings show that source-separation issues, government enforcement, market segmentation, financial issues and waste disposal issues are key factors influencing improved service provision. Meanwhile, on the demand side, we found that households are willing to support proposed regulatory improvement in service provision. Thus, we suggest industrial stakeholders to consider the aforementioned supply side issues in designing future service improvements that will take advantage of existing demand side feasibility.  相似文献

This article develops a model of cost and financing strategies for rural and peri-urban water supply and sanitation. It suggests that significant progress towards the World Summit for Children's goal of universal access to water supply and sanitation can be made if a combination of strategies is adopted. On the cost side, significant cost reductions should be possible through efficiency in resource use and reduction of system management costs. On the financing side, it suggests restructuring the financing of the sector with improved efficiency and greater cost recovery in urban services; full recovery of operation and maintenance costs; cost sharing through community contributions in kind such as local labour and financially in rural and peri-urban water supply for basic levels of service depending on willingness and ability to pay and full cost recovery for higher levels of service; a high degree of cost recovery in rural and peri-urban sanitation; development of institutional structures for both collection and management of revenues; development of alternate financing mechanisms such as rural credit schemes and revolving funds, adapted in specific country contexts, including the required institutional mechanisms; and additional allocations from governments and external support agencies. Additional government or external financing alone, while critical, will not of itself lead to effectiveness in the use of resources. Equally, cost recovery alone cannot lead to universal access and sustainable solutions. A composite set of actions is needed within which building capacities of institutions and people is necessary for sustainability .  相似文献

Faced with the task of communicating their combined social, environmental and economic impact, water service providers are seeking to report overall performance in an aggregated way. Such a methodology must be scientifically robust, easily communicated and allow benchmarking of performance while reflecting a transition towards sustainability. In this paper the ecological footprint (EF) is calculated for Sydney Water Corporation (SWC), using input-output analysis and land disturbance in an innovative approach that overcomes problems identified in the original EF concept. This pilot study has allowed SWC to gain some valuable insights into its impacts: SWC's annual EF is about 73 100 ha in terms of land disturbance. Of this, 54 000 ha are projected to become disturbed as a consequence of climate change, with the remainder of 19 100 ha being disturbed on SWC's premises (2400 ha) and on those of upstream suppliers (16 700 ha). Total on-site impacts equal 9300 ha, while indirect land disturb ance contributes 63 600 ha. The EF appears promising as an educational and communi cation tool and may have potential as a decision support tool. However, further research is needed to incorporate downstream impacts into the EF, which would have significant benefits to SWC in terms of assessing and communicating the organization's overall progress towards sustainability.  相似文献

This paper presents a method for assessing a community's sustainability prospects at a point in time. It argues that an improved methodology is needed to support the development of local area indicators. The method presented is community sustainability auditing. The ethical, conservative, competitive and co-operative aspects of sustainability are emphasized.The method uses an indicator approach within a protocol loosely inspired by International Standards Organization procedures. This involves the development of a set of questions for audit purposes, definition of indicators, analysis of the indicators in the light of the questions and a report summarizing a community's sustainability prospects.  相似文献

This paper aims to establish a framework in which potential methods for evaluating environmental impacts can be considered, with particular reference to the UK planning system. To do this a number of complementary ways of conceptualising sustainable development and making it more practical are outlined. Some basic arguments about the meaning of sustainability are reviewed; and some common misconceptions about the concept exposed. The concept of sustainability constraints is outlined and a functional distinction between quantitative and qualitative constraints is proposed. The adoption of sustainability constraints based on measures of environmental capacity is proposed. These suggest significant reductions in consumption of most environmental resources. The efficiency and sufficiency strategies that would be needed to meet the proposed quantified constraints are outlined. In conclusion, evaluation processes and indicators of sustainability, including environmental foot-printing and environmental impact assessment, are discussed, offering some pointers towards the type of measures that will be needed to help implement sustainability strategies.  相似文献

Environmental management systems and sustainable development   总被引:1,自引:0,他引:1  
The idea of sustainable development was first brought to widespread attention as a global issue; however, it is increasingly being applied at more local levels down to that of individual companies. This raises the potential danger that sustainable development will come to be predominantly identified with the preservation of the organisation involved. A likely outcome is that management decision-making will tip the balance too far in favour of people-centred interests as against environmental interests. An initial step in preventing this is to make any bias in the balance of interests transparent to management. To do this, a model of sustainability is set up in terms that provide a context for the implementation of a quality based environmental management system such as that specified by the International Standard, ISO 14001. In response to inherent uncertainty, a precautionary approach is adopted. The implications of this model for the structuring of critical environmental management system elements are then discussed and a way to generate an indicator of bias proposed. The content of an audit, which would measure the extent to which an organisation has a management system competent to measure and monitor this bias, is also discussed and proposed as another useful indicator.  相似文献

While the concept of sustainable development brings together concepts of economic, environmental and social sustainability, much has been said regarding inherent tensions between them. Conflicts between economic and environmental objectives, in particular, have been noted as restraining efforts to instigate transitions to environmental sustainability, with growth ambitions limiting environmental policy to “win–win” cases. This paper argues that they can also play complementary roles in managing transitions by creating inclusive visions for rallying actors and resources. This is explored by looking at a case of sustainable regeneration in Wales, UK. Using as a case study the Arbed scheme, an area-based project established in 2009 to retrofit housing stock for energy efficiency, this paper shows how the scheme explicitly addresses economic, environmental and social aspects of sustainability; and, in particular, how sustainable development aims constituted a guiding vision that supported the formation of actor and resource networks necessary for large-scale retrofitting.  相似文献

Water companies have to ensure that supply and demand for water are kept in balance. This can necessitate the development of new sources of supply that may conflict with local wildlife interests. The paper reviews the policy background to this problem in the UK. It then presents an appraisal of a project to artificially recharge an aquifer with river water during the winter period, and abstract the water in the summer to augment shortages during drought conditions. The research investigates the preference trade-offs of water company customers between increasing security of supply and potential environmental impacts on local wetland sites and river flows. A cost-benefit analysis of the project is presented. The study also reveals a disparity between the site-specific valuation and that generated using the Environment Agency's approved benefit transfer guidelines.  相似文献

This paper draws upon the DISCUS (Developing Institutional and Social Capacity for Sustainable Development) research project, co-funded by the European Commission. The project was undertaken during 2001 – 2004 and involved an in-depth study of 40 European towns and cities in order to understand the institutional and social factors and conditions that might contribute to policy ‘achievement' or ‘failure' in local sustainable development policy and practice. Based on the findings of this research it proposes a conceptual framework for local sustainable development, linking the concepts of institutional capital, social capital and governance to provide a model for understanding the governing of local sustainability. The research shows that in those cases that exhibit sustainable development policy achievements, there are also greater levels of civil society activity and knowledge regarding sustainability issues, and high levels of institutional capacity. Confident local government is crucial to the development of institutional capacity and to institutional learning. One aspect of this is local authorities being equipped to address the longer-term issues and to have a strategic vision for a sustainable future.  相似文献

My main purpose in this paper is to consider ways to reorient the school community towards a culture of sustainability. Education for sustainability (EfS) is generally regarded as learning how to make decisions and take action that consider the long-term future of the environment, economy and social justice of communities (UNESCO, Education for Sustainability. From Rio to Johannesburg: lessons learnt from a decade of commitment, 2002). Education for sustainability is usually and was historically applied in schools through an environmental education approach. My research is significant because the goal of transformation towards sustainability is considered from the perspective of school governance. In this paper I present three case studies: Forest School, a small independent rural school; Riverdale School, a small independent regional city school; and Oakfield School, a large government school situated in a regional city (all school names are pseudonyms). The research has concluded in the small schools and is in progress at Oakfield. In the literature, it is generally accepted that small schools have the potential for sustainability (for example, Sterling, Sustainable Education: re-visioning learning and change, Green Books, 2001, pp. 48, 69; Carnie, 'Educating on a Human Scale', Resurgence, 204, 2001). In the literature, there is no consensus on the potential for sustainability of medium or large schools. The ongoing Oakfield School project is particularly significant because of the issue of school size. In the Oakfield project, the intention is to document progress towards a culture of sustainability in a large school. In this paper, I conclude that a focus on the development of a participative democracy is conducive to cultural change for sustainability in a small school. I suggest that this will also be the case in a larger school, but that more complex structures for decision making as the basis for transformative learning are required.  相似文献

As a result of the UK Government's waste policy, which increasingly encourages sustainable development, and the realisation that water in the UK cannot be treated as an unlimited resource, there is growing interest in reducing the demand for water by industry. A series of industrial waste minimisation clubs have been set up within the country. This paper identifies the effectiveness of these clubs in reducing the demand for water. An overview of some of the clubs show how there is a major discrepancy between potential and implemented water savings, whilst a more detailed analysis of three specific examples show how water demand and cost to the company can be reduced, with the project paying for itself within around 1 year. It appears that companies are able to reduce water consumption by approximately 30%. If this level of saving was taken up by the entire industrial sector in England and Wales, water consumption could be reduced by approximately 1500 Ml/day. This reduction would be more significant in regions of lower rainfall, for example East Anglia and Southeast England.  相似文献

Food and nutrition security is a persisting global issue and, in addition, food systems are now facing a new set of intersecting economic, social and environmental challenges. Recurrent socio-economic and biophysical changes put the sustainability of food systems at risk. There is an urgent need to develop knowledge-based tools to assess and monitor food sustainability and to identify pathways for food security and resource conservation. The systemic nature of these interactions calls for multidimensional approaches and integrated assessments for decision-making to guide change. This paper reviews social–ecological system frameworks with the view to conceptualize the sustainability issues that affect the food systems. It is argued that the understanding of the food systems as social–ecological systems, and inputs from the theories of vulnerability and resilience in particular, can provide the concepts necessary to understand and model the complex system dynamics involved in the multiple interactions between human and natural components.  相似文献

The modern environmental management literature stresses the need for community involvement to identify indicators to monitor progress towards sustainable development and environmental management goals. The purpose of this paper is to assess the impact of participatory processes on sustainability indicator identification and environmental management in three disparate case studies. The first is a process of developing partnerships between First Nations communities, environmental groups, and forestry companies to resolve conflicts over forest management in Western Canada. The second describes a situation in Botswana where local pastoral communities worked with development researchers to reduce desertification. The third case study details an on-going government led process of developing sustainability indicators in Guernsey, UK, that was designed to monitor the environmental, social, and economic impacts of changes in the economy. The comparative assessment between case studies allows us to draw three primary conclusions. (1) The identification and collection of sustainability indicators not only provide valuable databases for making management decisions, but the process of engaging people to select indicators also provides an opportunity for community empowerment that conventional development approaches have failed to provide. (2) Multi-stakeholder processes must formally feed into decision-making forums or they risk being viewed as irrelevant by policy-makers and stakeholders. (3) Since ecological boundaries rarely meet up with political jurisdictions, it is necessary to be flexible when choosing the scale at which monitoring and decision-making occurs. This requires an awareness of major environmental pathways that run through landscapes to understand how seemingly remote areas may be connected in ways that are not immediately apparent.  相似文献

The UK government has identified the land‐use planning system, and development plans in particular, as potentially powerful instruments for integrating national sustainability objectives into strategic decision making at local levels. One method for achieving this is through the use of so‐called ‘sustainability appraisals’, which are an extension of the established system of environmental appraisal used by planners since the early 1990s. A national framework is outlined in Planning Policy Guidance Note 12. Local authorities are now expected to conduct an environmental appraisal of their development plans which covers sustainable development issues. However, little research has been conducted on the effectiveness of current guidance in meeting this aim. By evaluating the implementation of sustainability appraisals nationally, this paper suggests that while government advice to appraise is generally being applied, the actual use of key sustainability principles in practice is rather variable. It then discusses these findings in relation to the changing context of appraisals in the UK and other national planning systems.  相似文献

One of the most challenging tasks of water supply utilities is planning the timing and quantity of new water supply sources as demand for water consumption grows. Many water supply utilities target on meeting 100% of their customers' needs based on scenario‐based deterministic demand projections numbers even though there are uncertainties in both supply and demand values. This may result in under or overly conservative approach in assessing future needs. In this article, a level‐of‐service concept is introduced to capture a utility's willingness to accept a given level of risk, plan for it, and invoke a management strategy during extreme events than build a facility to accommodate those in planning for new water supply sources. Accounting for uncertainties in both supply and demand help quantify reliability by achieving a prescribed level of service. The major benefit of such an approach for planning future water supply is that it allows policy makers to evaluate the use of adaptive water management strategies and develop supply in an incremental fashion as demand warrants it. For example, if a given level of service cannot be reliably met with the existing system at a future time t, an incremental water supply project would come online to bring the required reliability level up but no more.  相似文献

Land resource sustainability for urban development characterizes the problem of decision-making with multiplicity and uncertainty. A decision support system prototype aids in the assessment of incremental land development plan proposals put forth within the long-term community priority of a sustainable growth. Facilitating this assessment is the analytic hierarchy process (AHP), a multicriteria evaluation and decision support system. The decision support system incorporates multiple sustainability criteria, weighted strategically responsive to local public policy priorities and community–specific situations and values, while gauging and directing desirable future courses of development. Furthermore, the decision support system uses a GIS, which facilitates an assessment of urban form with multiple indicators of sustainability as spatial criteria thematically. The resultant land-use sustainability scores indicate, on the ratio-scale of AHP, whether or not a desirable urban form is likely in the long run, and if so, to what degree. The two alternative modes of synthesis in AHP—ideal and distributive—provide assessments of a land development plan incrementally (short-term) and city-wide pattern comprehensively (long-term), respectively. Thus, the spatial decision support system facilitates proactive and collective public policy determination of land resource for future sustainable urban development.  相似文献

This paper assesses the credentials of the planning system in dealing with low-impact developments in the countryside. Forming part of the wider debate on sustainable development in the UK, low-impact developments challenge contemporary rural planning orthodoxy. A detailed case study of Brithdir Mawr in Pembrokeshire Coast National Park reveals the complexities and sensitivities inherent in operationalizing sustainability in this context. The results reveal a planning system reluctant to embrace unconventional lifestyles and methods claiming to be sustainable. It is concluded that the planning system and low-impact developments both need to demonstrate their sustainability credentials in a more direct and empirical manner. Ultimately this could be built into revised criteria for allowing dwellings in the open countryside. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

This paper intends to present a critical review of the planning models that can be used for sustainable water resource development. Three types of models are identified and assessed: (1) economic analysis models; (2) decision analysis models; and (3) systems analysis models. The methodology adopted in this paper is based on first describing the different types of models and then synthesizing and evaluating these models in terms of their theoretical underpinnings, applications, strengths and weaknesses. Each model is investigated with respect to its utility in addressing sustainability in water resource management. The study concludes that decision-based and system-based models may offer a wider spectrum of concepts than economic models in addressing multi-objective, multi-actor or 'wicked' problems in water management and resource sustainability.  相似文献

Over the course of Australia's Millennium Drought, urban water managers gained more appreciation of householders' willingness and capacities to respond to water shortages and restrictions, including by installing rainwater tanks (RWTs) for watering gardens. How urban water managers regard tanks and tank users gives insight into their understandings of social sustainability, as found in interviews conducted in 2006 and 2010. These also revealed a growing distance between policymakers and water providers pursuing a broader approach to sustainability in their communities. The RWT is considered here as a limit case for paradigms of urban water management: it challenges conventional distinctions (such as provider/consumer) and heralds a new hydropolitics. These challenges are discussed as seven kinds of trouble with tanks: (1) incompatibility with the management model and vision of modernity enshrined in the ideal of centralised provision in control of accredited water experts; (2) anxieties about control and risk aroused by these private on-site facilities and their non-expert users; (3) equivocation over their environmental effects, normally assessed in hydrological terms that downplay the benefits of green streetscapes; (4) inexplicability of their popularity within dominant economically rationalist models of customers; (5) educational effects that exceed rationalist, individualist models of learning and require more socially realistic, culturally intelligent and practice-oriented approaches; (6) generation of enthusiasms that are spurned as threats to rationality instead of harnessed to energise the sustainability journey and (7) community-building effects that are unthinkable within the neoliberal customer paradigm but graspable to water managers through lay concepts like “dinner table conversations”.  相似文献
