Sustainability: meaning and measurement with application to agriculture

Sustainability refers to having the ability to meet present needs without impacting on future generations to meet their needs. It incorporates social, economic and environmental aspects, and as a measure of sustainability, a range of sustainability indicators at the economy, regional, and individual level, have been suggested. However, given the complex and multidisciplinary nature of the concept, an interdisciplinary approach is necessary. Sustainability is not something that is easily measurable, and the aim of this paper is to present a conceptual framework for quantifying sustainability on the basis of social economic efficiency. According to neoclassical economic theory, economic activity will only be sustained by the private sector as long as it is profitable. However, private economic decisions do not always ensure long-term sustainability of environmental resources or production. The approach suggested here is to derive a measure of social economic efficiency as a measure of sustainability. For dairy farmers, increased productivity has been emphasized, while recognizing the need to reduce greenhouse emissions, pests and disease, nutrient run-off into the environment and degradation of the soil structure. By incorporating environmental and economic impacts, a fuller measure of efficiency, social economic efficiency, and sustainability of the farming practice can be developed.

Measuring regional sustainability: lessons to be learned

Developing tools for measuring progress toward sustainability has proven a challenging task. Indicators offer an excellent means to explore the success or otherwise of management strategies. They also allow reporting social, economic and environmental aspects of sustainability. To ensure that the tools developed are effective in measuring the progress toward sustainable futures, an evaluation of the methods and the indicators used must be undertaken so that with progress there is learning and with the new knowledge methods can be redesigned to better advance sustainability. This paper discusses a study carried out in the south west region of Victoria, Australia, using indicators as the basis for developing a tool to measure progress toward sustainability. By evaluating the methods and indicators used in the study this paper provides an insight into the challenges encountered and the lessons learned. Issues explored include selecting indicators, collating data, integrating social, economic and environmental aspects of sustainability and using an adaptive approach.

Knowledge management in a major construction firm in Tawian: a case study-examining the impacts of KM initiatives within the firm.

This paper addresses knowledge management (KM) in a project management organisation through a case study. The case study organisation is a small- edium sized Taiwanese-owned construction company (staff size of approximately 50) with an annual turnover of approximately TWD50 (AUD$1.85) billion. Approximately one half of the company comprised project-related staff (e.g. construction project management, project documentation, estimation, procurement, and design), while the other comprised administrative and business-related staff (e.g. office administration and management, business development, and finance and accounting). The researcher undertook a series of surveys and one-on-one interviews whilst ‘embedded’ for several months with the organisation. As part of a larger research project, this case study was one of four case studies conducted in major construction organisations in Singapore, Taiwan, and Australia. The study revealed the recognition, importance and commitment of organisational culture to KM, and the effects the knowledge management initiatives have on the organisation’s ability to manage knowledge across its projects and deliver the projects at various ‘levels’ of the organisation (individual, project, departmental, and corporate). It concludes that a technologically and functionally sound KM infrastructure does not necessarily assure an organisation with a capability to manage knowledge. Organisations need to ensure that the KM repository is made up of quality and relevant contents (not just quantity), and that corporate culture (especially the willingness of individuals to share what they know) is a critical determining factor to the organisation’s ability to share, apply and create knowledge (i.e. low sharing capability leads to low application and creation capabilities).

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.

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.
