Evaluation of coastal zone sustainability: an integrated approach applied in Shanghai Municipality and Chong Ming Island

A systems approach has been applied to the examination of sustainable development in the coastal zone. This complex system is envisaged as comprising three sub-systems: environment and resources, economic development and society. A sustainability indicator system based on these three sub-systems has been set up to evaluate the nature of development in the coastal zone. The administrative regions of the Municipality of Shanghai and Chong Ming Island (in the Yangtze Estuary) have been selected as two coastal zones in which to demonstrate the feasibility and effectiveness of the approach. The approach indicated that the development process in Shanghai is one of weak sustainability with relatively rapid social and economic development at the cost of environment and resource degradation. In contrast, social and economic development in Chong Ming County has been limited to protect the regional environment and resources indicating a more sustainable approach to development.     

The Environmental sustainability of mining in Australia: key mega-trends and looming constraints

At first ‘sustainable mining’ could be perceived as a paradox—minerals are widely held to be finite resources with rising consumption causing pressure on known resources. The true sustainability of mineral resources, however, is a much more complex picture and involves exploration, technology, economics, social and environmental issues, and advancing scientific knowledge—predicting future sustainability is therefore not a simple task. This paper presents the results from a landmark study on historical trends in Australian mining, including ore milled, ore grades, open cut versus underground mining, overburden/waste rock and economic resources. When complete data sets are compiled for specific metals, particular issues stand out with respect to sustainability—technological breakthroughs (e.g. flotation, carbon-in-pulp), new discoveries (e.g. uranium or U), price changes (e.g. Au, boom/bust cycles), social issues (e.g. strikes), etc. All of these issues are of prime importance in moving towards a semi-quantitative sustainability model of mineral resources and the mining industry. For the future, critical issues will continue to be declining ore grades (also ore quality and impurities), increased waste rock and associated liabilities, known economic resources, potential breakthrough technologies, and broader environmental constraints (e.g. carbon costs, water). For this latter area, many companies now report annually on sustainability performance—facilitating analysis of environmental sustainability with respect to production performance. By linking these two commonly disparate aspects—mining production and environmental/sustainability data—it becomes possible to better understand environmental sustainability and predict future constraints such as water requirements, greenhouse emissions, energy and reagent inputs, and the like. This paper will therefore present a range of fundamental data and issues which help towards quantifying the resource and environmental sustainability of mining—with critical implications for the mining industry and society as a whole.     

The Wild Kangaroo Industry: Developing the Potential for Sustainability

Wildlife resources the world over have long been subject to harvest and management. As wildlife uses have grown, so too have the need and desire to ensure their sustainability. This new context of sustainability presents opportunities to merge ecological, economic and social elements to foster development. This paper presents the management and harvesting of wild kangaroos as an example of the potentially sustainable use of a natural resource. Some comparisons are drawn between the use of other wild living resources, deer in Europe and crayfish in Western Australia. However, sustainability of kangaroo species and the industry is not just a matter of market economics and ecology, it must also be socially sustainable. The public policy instrument of a statutory advisory board with a marketing function is proposed in order to integrate the cultural and social aspects of kangaroo management with the economic and ecological aspects. Through such integration, full sustainability of a wild resource then might be achieved.     

Sustainable regeneration: a guiding vision towards low-carbon transition?

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.

Sustainability of the dimension stone industry in Zimbabwe—challenges and opportunities

The rapid expansion of the dimension stone and black granite industry in Zimbabwe in the 1990s, a result of increasing domestic and international demand for black granite, has ushered in new challenges and opportunities for producers and beneficiaries alike. This article investigates the social, environmental and economic challenges emanating from the export boom, the economic opportunities presented by the expanding market and the potential role the robust industry could play in regional economic development and poverty alleviation. The article evaluates the long-term sustainability of the dimension stone industry and recommends the reinvestment of revenues into diversification of the regional economic base, upgrading of local infrastructure, further processing of rough stone before export and encouragement of micro-businesses to enhance sustainability. The author argues for modification of economic incentives to incorporate environmental and social objectives in order to enhance sustainability. The need for a holistic approach to policies affecting the exploitation, processing and marketing of granite resources and their products is recognized. More research on the operations of the industry is called for.     

Multicriteria Evaluation of Water Resources Sustainability in the Context of Watershed Management1

Kang, Min‐Goo and Gwang‐Man Lee, 2011. Multicriteria Evaluation of Water Resources Sustainability in the Context of Watershed Management. Journal of the American Water Resources Association (JAWRA) 47(4):813‐827. DOI: 10.1111/j.1752‐1688.2011.00559.x Abstract: To evaluate water resources sustainability at the watershed scale within a river basin’s context, the Water Resources Sustainability Evaluation Model is developed. The model employs 4 criteria (economic efficiency, social equity, environmental conservation, and maintenance capacity) and has 16 indicators, integrating them using their relative weights. The model is applied to evaluate the water resources sustainability of watersheds in the Geum River basin, South Korea. A geographic information system is employed to efficiently build a database for the indicators, and the values of the indicators are normalized using the probability distribution functions fitted to the datasets of the indicators. The evaluation results show that, overall, the water resources sustainability of the watersheds in the upper basin is better than other areas due to the good environmental conditions and the dam management policies of South Korea. The analysis of the correlations among the model’s components and the comparison between the results of the model and the Water Poverty Index show that the model can provide reasonable evaluation results for the water resources sustainability of watersheds. Consequently, it is concluded that the model can be an effective tool for evaluating the states of water resource management from the perspective of sustainable development and provide a basis on which to create policies for improving any inadequacies in watersheds.     

Qualifying irrigation system sustainability by means of stakeholder perceptions and concerns: lessons from the Segarra‐Garrigues Canal,Spain

When planning interventions, water and land resource managers increasingly need to take the opinions of stakeholders into account. In the present study, stakeholders’ concerns in a multifunctional water system are assessed, with a focus on the debate about the sustainability of irrigation projects in stressed and competing water contexts. The selected case study pertains to the Segarra‐Garrigues irrigation canal (Spain), the promotion of which has generated social debate and mobilization, as well as pronouncements from European authorities for ensuring its environmental sustainability. Data was collected through semi‐structured interviews and analysed by means of a new codification system for identifying the affinities and conflicts arising from existing water demands. Results show that sustainability concepts are more present in civil society than in public administration and private services or the rural community. However, social sustainability and environmental sustainability are a priority for most stakeholders, while the economic perspective of sustainable development has been conditioned by the first two. These results can be used by relevant authorities as a first step in customizing their interventions, as they provide a clear initial idea of what stakeholder priorities are in the framework of sustainable development.     

Water and sustainability

This inquiry summarizes global water resources and patterns of use, applies indicators of water sustainability in order to identify areas of water stress, and examines prospects for water sustainability in the list century. A long-range conventional development scenario is introduced based on a vision of the future in which the values, consumption patterns and dynamics of the Western industrial society will be progressively played out on a global scale. The scenario is driven by commonly cited projections of population and economic growth, assumes no major changes in water policy and, following historic trends, incorporates progressive improvements in the efficiency of water use. The scenario helps clarify the constraints of a conventional picture of water development, and provides a useful point of departure for examining alternative long-range scenarios and their implications for water and development policy. In the conventional development scenario, there is growing pressure on water resources, particularly in developing regions. Strategies for beginning a transition to a sustainable water development path are summarized .     

The development and application of water management sustainability indicators in Brazil and Scotland

This paper reports the formulation and application of a framework of catchment-level water resource management indicators designed to integrate environmental, economic and social aspects of sustainability. The framework of nine indicators was applied to the River Dee and River Sinos catchments in Scotland and Brazil, respectively, following an indicator selection process that involved inputs from water management professionals in both countries, and a pilot exercise in Scotland. The framework was found to capture a number of key sustainability concerns, and was broadly welcomed by water resource managers and experts as a means of better understanding sustainable water resource management. Issues relating to poor water quality and public water supply were particularly prominent in the findings for the Sinos, while findings for the Dee suggested that more attention might be focused on building institutional capacity and public participation in catchment management. The use of some proxy indicators was required in both catchments due to poor data availability, and this problem may hinder the further development of indicator frameworks that attempt to better integrate environmental, economic and social dimensions of sustainability.
