Producing a GIS based multiple criteria analysis tool for regional sustainability assessment: the problem of weighting

Decision support tools will be useful in guiding regions to sustainability. These need to be simple but effective at identifying, for regional managers, areas most in need of initiatives to progress sustainability. Multiple criteria analysis (MCA) is often used as a decision support tool for a wide range of applications. This method allows many criteria to be considered at one time. It does this by giving a ranking of possible options based on how closely each option meets the criteria. Thus, it is suited to the assessment of regional sustainability as it can consider a number of indicators simultaneously and demonstrates how sustainability can vary at small scales across the region. Coupling MCA with GIS to produce maps, allows this analysis to become visual giving the manager a picture of sustainability across the region. To do this each indicator is standardised to a common scale so that it can be compared to other indicators. A weighting is then applied to each indicator to calculate weighted summation for each area in the region. This paper argues that this is the critical step in developing a useful decision support tool. A study being conducted in south west Victoria demonstrates that the weights chosen can have a dramatic impact on the results of the sustainability assessment. It is therefore imperative that careful consideration be given to determining indicator weights in a way that is objective and fully considers the impact of that indicator on regional sustainability.

Multiple criteria sustainability modelling: case study on school buildings

This paper describes development of a computer-based tool for sustainability modelling using multiple criteria, and preliminary conclusions from doctoral research being undertaken into the relationship between key sustainability indicators. The model used in both cases produces a sustainability index with an accept/reject threshold of one that has the potential to completely replace traditional net present value methods. Minimum performance benchmarks are prescribed and must be observed - often by trading off performance across the full criteria set. Sustainability is shown to be capable of objective (numeric)· analysis for new projects, existing facilities, or indeed any product or asset. A combination of investor-centred and community-centred motivations can also be explored in the model. Known as SINDEX, the tool has industry-wide application, both locally and abroad, and represents a paradigm shift in project evaluation techniques. Furthermore, its multi-discipline considerations underscore the importance of a team approach to sustainability modelling and the need for people to work more closely together when dealing with complex problems. The results of twenty case studies of actual high schools constructed and operated in New South Wales (Australia) are also presented and the relationships between the key sustainability indicators are explored and interpreted.

Developing business community portals for SMEs-Issues of design, development and sustainability

Governments worldwide are using funding initiatives to encourage small businesses to adopt e-commerce technology. In Australia both State and Federal Governments have encouraged e-commerce uptake through the funding of Internet portal developments that have a specific community or business focus. The success of such portals, as with many Web developments, has been mixed and there is little evidence of any evaluation of the effectiveness of such investments. This paper reports on research into an Australian B2B business community portal from launch to closure. A survey and in-depth interviews with portal participants were undertaken. The research sought to understand how the portal had been developed, and what factors may have contributed to its demise. The findings identified a number of factors, not discussed in the literature, that are important in portal development. These include: how the development process is undertaken; technological readiness of the small business owners; meeting business expectations; and understanding the business community stakeholders. The results from this study suggest that portal projects such as this are problematic and funding bodies such as governments need to understand the factors that contribute to success before funds are committed.

Community-based sustainability: conservation in the Ballarat region

The discourse of sustainability is promoted internationally, with the United Nations declaring 2005-2014 as a Decade for Education for Sustainable Development. There is discussion concerning the nature, status and significance of Education for Sustainability and its relationship with the somewhat established discourse of environmental education. This debate requires continuing theorising and one approach is to reflect critically on specific examples of sustainability within specific communities. This article seeks to promote further discussion about sustainability, and to contribute to ongoing theorisation about Education for Sustainability, by considering a particular instance – that of environmental sustainability in the Ballarat region of Victoria. The case study suggests that implementation of this local environmental sustainability strategy was dominated by technocratic and individualistic ideologies.

The sustainability of health promotion interventions for different levels of social organization

In health promotion, enthusiasm for sustainability has frequently overshadowed critical reflection with regard to whether this aim is warranted, let alone feasible. Consequently, the not insubstantial body of literature on sustainability in health promotion is not particularly helpful to decision makers. In this paper we seek to provide some guidance for the development of sustainability for health promotion interventions, arguing that it is necessary to be able to differentiate between (i) levels of social organization which are the focus of change, (ii) the programmes and agencies which are the means employed to achieve change, and (iii) the outcomes or effects that are achieved. Furthermore, funding allocations need to be congruent with programme characteristics if one is serious about achieving sustainability.

New visions for addressing sustainability

Attaining sustainability will require concerted interactive efforts among disciplines, many of which have not yet recognized, and internalized, the relevance of environmental issues to their main intellectual discourse. The inability of key scientific disciplines to engage interactively is an obstacle to the actual attainment of sustainability. For example, in the list of Millennium Development Coals from the United Nations World Summit on Sustainable Development, Johannesburg, 2002, the seventh of the eight goals, to "ensure environmental sustainability," is presented separately from the parallel goals of reducing fertility and poverty, improving gains in equity, improving material conditions, and enhancing population health. A more integrated and consilient approach to sustainability is urgently needed.

The welfare economics of measuring sustainability: a new approach based on social choice theory and systems analysis

This paper presents a new measure of sustainability within a welfare economics framework. Gross domestic product (GDP) can be used as an indicator of sustainability if the GDP estimates are undertaken within a cost-benefit analysis framework based on social choice perspectives. Sustainability is dependent on a healthy and functioning socio-economic and environmental (SEE) system. Economic development can damage the SEE system through resource degradation, over-harvesting and pollution. This paper addresses the tensions between economic development and sustainability by undertaking a number of SEE-based adjustments to GDP based on social choice perspectives in order to measure sustainability. These adjustments include the environmental and social costs caused by economic development such as water pollution, the depletion of non-renewable resources, and deforestation. Thailand is used as a case study for a 25 year period (1975-1999). The results show a divergence in terms of GDP per capita and the SEE-adjusted GDP per capita figure. The paper concludes that, with increasing environmental and social costs of economic development, pursuing such extreme high growth objectives without due environmental and social considerations can threaten present social welfare and future sustainability.

Sustainability and health : supporting global ecological integrity in public health

Radical changes in the biosphere and human interaction with the environment are increasingly impacting on the health of populations across the world. Diseases are crossing the species barrier, and spreading rapidly through globalized transport systems. From new patterns of cancer to the threat of global pandemics, it is imperative that public health practitioners acknowledge the interdependence between the sustainability of the environment and the sustainability of the human species.* Why are issues of global and local sustainability of increasing importance to the public's health?* Why do issues of sustainability require new practices within the professions of public health?* How can future and current public health practitioners develop those new practices?Drawing on scientific evidence of global and local environmental changes, Sustainability and Health offers a thorough background and practical solutions to the overlapping issues in environment and health. It examines potential and existing responses to global and local environment and health issues, involving individuals, community, industry and government. The authors introduce a range of emerging conceptual frameworks and theoretical perspectives, link IT and epidemiology and explain how scoping can link program design, delivery, data collection and evaluation in projects from their very beginning. Public health practitioners need to be able to manage health issues that cut across environmental, economic and social systems and to develop the capacity for leadership in facilitating change. Incorporating learning activities, readings, international case studies and an open learning approach, this is a valuable resource for students of public and environmental health, as well as medical, environmental and health science professionals.
