Thinking/acting locally/globally: western science and environmental education in a global knowledge economy

This paper critically appraises a number of approaches to 'thinking globally' in environmental education, with particular reference to popular assumptions about the universal applicability of Western science. Although the transnational character of many environmental issues demands that we 'think globally', I argue that the contribution of Western science to understanding and resolving environmental problems might be enhanced by seeing it as one among many local knowledge traditions. The production of a 'global knowledge economy' in/for environmental education can then be understood as creating transnational 'spaces' in which local knowledge traditions can be performed together, rather than as creating a 'common market' in which representations of local knowledge must be translated into (or exchanged for) the terms of a universal discourse.

Lifecycle environmental impact and cost analyses of steel bridge piers with seismic risk

Lifecycle approaches have found their wide applications in analyzing, evaluating and assessing technologies and management methods in the infrastructure systems. While environmental problems such as global warming have become a serious issue in the world, researchers and practicing engineers in civil engineering have to pay attention to environmental impacts as well as function, safety, cost and aesthetics in the
whole lifecycle of civil infrastructures. In addition to the normal lifecycle activities accompanied with operation and aging, the effects of natural hazards such as earthquakes with a low occurrence probability but a high
hazard loss require a full consideration in determining both lifecycle cost and lifecycle environmental impact. In this research, an approach is proposed to predetermine the lifecycle environmental impact and costs of bridges from their construction and maintenance as well as the losses and recovery after natural hazards. Based on this research, it becomes possible to quantitatively outline the roles of bridge construction, maintenance and earthquake in both environmental impact and cost in the whole lifetime of a bridge, especially their constituent parts from seismic losses and recoveries.

Investigating social marketing, benchmarking and public policy development in environmental management

This paper discusses, an application of social marketing relating to pro-environmental awareness and social change. The integration of consumer behaviour theory into social marketing has been highlighted in the literature as requiring greater attention. Social marketing campaigns, like all marketing activities, rely on an understanding of stakeholders' attitudes and motivations in regard to the issue of concern, as well as towards the desired modified behaviour or lack of behaviour. The study highlights the marketing paradigms of benchmarking and social marketing in a not for profit governmental environment. Serrated Tussock has been designated as a weed of national significance and therefore the program has national implications (Thorp 2000). Even though issues associated with introduced species are less publicised than other environmental issues on the world stage, the associated environmental problems are no less severe than those caused by production and consumption activities. Weed control is a widespread problem facing individuals, communities and governments at all levels. A triangulatory approach, involving three distinct phases and incorporating both qualitative and quantitative tools, was used for the research design. The qualitative phase involved focus groups and in depth interviews with landholders, focus groups with professionals in the field and a focus group of key stakeholders. The mail survey resulted in a representative sample of 608 usable responses from the infestation area. The research conducted in this study illustrates how the various stages in the social marketing process were achieved and recommendations consistent with social marketing theory were generated.

Environmental attitudes of pre-service teachers : a conceptual and methodological dilemma in cross-cultural data collection

Human generated environmental problems are significant issues of global concern. Despite this, varying attitudes towards environments continue to exist across the globe, impacting on environmental decision-making and action at local, national and international levels. This paper probes some of the similarities and differences in environmental attitudes amongst pre-service teachers in Australia, Republic of Maldives and Indonesia. Data were collected using an established environmental attitude questionnaire and individual interviews. The three communities exhibited a similar range of environmental attitudes using the established questionnaire but significant differences emerged when the interview data were analysed phenomenographically. These differences reflect diversity within and across cultural groups that cannot be satisfactorily explained by the theory underpinning the established questionnaire. Consequently, a revised conceptual framework is proposed.

Environment, resource sustainability and sustainable behaviour: exploring perceptions of students in South West Victoria

The movement toward a sustainable future has begun in many parts of the world, as the seriousness of the environmental problems faced by the planet become more widely recognised. Waste reduction, improved efficiency of energy use, water saving devices and changes in modes of transport are the first steps in the transition to a sustainable future. The students of today will be the decision makers of tomorrow and, thus, can have a significant effect on future development and the environmental
impacts of that development. If students today are to become active participants in the environmental decision-making process, education for sustainability becomes a key component in ensuring sustainable futures. There is a need to establish data describing students’ attitudes toward environmental and resource sustainability issues so that challenges to implementing sustainable development policy can be better recognised. The aims of this study were to identify the perceptions of students in
the south west region of Victoria regarding environment and resource sustainability, and to identify their level of participation in sustainable behaviours. A survey of students has found that global environmental issues perceived by students as being in urgent need of attention were access to freshwater, loss of tropical rainforest and exhaustion of natural resources. At the local level the most urgent issues identified were water pollution, salinization and soil degradation, and clearing of native vegetation. Students perceive that Australians are overusing natural resources. They indicated particular concern for the sustainability of fossil fuels, water, coastal environments and fisheries resources. The results of this study indicate that students are responding to concerns for the environment and resource sustainability by embracing some forms of sustainable behaviour. However, as educators we need to ensure that
the link is made between environment and resource sustainability and the implementation of policies that will further encourage sustainable behaviour.

'Green' treatment of acid mine drainage - a step towards sustainability

Sustainability is becoming increasingly important in the mining and mineral processing industries and must incorporate the associated waste products. Acid mine drainage (AMD) is one such by-product and is one of the most serious environmental problems facing the minerals industry today. The oxidation of sulphidic mine wastes often continues for a substantial period of time after mine closure, resulting in difficult and costly remediation and rehabilitation works. Mining companies are often reluctant to spend increasing amounts of money on waste treatment when the mine life is limited or even finished. Hence a simple, low maintenance and low-cost method of treating AMD is required. Whilst this paper does not address the issue of AMD, it does propose methods for removal of individual species from AMD with potential benefits, including raising AMD pH.

A novel concept of using biosolids as a biological adsorbent, or ‘biosorbent’, of metals from AMD is being investigated at a laboratory/pilot scale level. Biosolids are a by-product resulting from the biological treatment of wastewater, and have been previously shown to adsorb metals from aqueous solutions. This could lead to an environmentally sustainable or ‘green’ method for treating both AMD discharges and disposing/reusing the biosolids.

The result of a laboratory-scale study of the biosorption of Zn(II) is presented in this paper. Physical parameters including reaction kinetics, mixing speed and solution pH were investigated. Solution pH also rose an average of 2 pH units over the 24 hour equilibrium time – a valuable side effect when treating acid mine drainage. The outcome of the study highlights the usefulness of biosolids as a biosorbent for the removal/recovery of metal ions from acid mine drainage. A simple, low-cost treatment technology requiring low maintenance would be beneficial to the mining industry to address some issues relating to AMD and would help integrate environmental and economic considerations into sustainable environmental management.

Ecologically sustainable development and architecture: the impact of rating tools

The concept of Ecologically Sustainable Development (ESD) has become an important issue – albeit often scarcely applied – in the design of commercial buildings. To encourage the adoption of sustainable strategies in the practice of design and to address the environmental problems caused by these developments, governments and organisations of various countries have proposed the adoption of scorecard rating tools to inform designers of the impact of their decisions and to present a way of establishing project goals and objectives early in the design process. In Australia, the recent introduction of the Green Star Rating Tool (Office Design) is believed to provide the architects with a ‘whole-of-building’ assessment of the environmental impact of their design by creating a checklist against which to benchmark performance. This paper follows the design of a commercial building, evaluating the impact of Green Star in the overall process. The results of the study suggest the need to include the use of scorecard rating tools in a more integrated model, where ESD is considered at every stage of design and construction rather than being a separate component applied only to promote the ‘greenness’ of a building. Rating tools can be an asset to the design team, provided sustainable requirements are reinforced throughout the entire process.

Conceptual framework of the precautionary principle approach in the decision-making process

This article reviews the precautionary principle as an approach in addressing decisions with far reaching environmental consequences under scientific uncertainty. The precautionary principle is intended to assist with structuring environmentally risky decisions toward sustainable development. It responds to the lack of scientific evidence of a potential environmental problem. There is currently no framework to assist with the process indicating the areas of importance and stages of decisionmaking. This paper suggests a framework to assist with the process of decision-making for complex environmental problems. The main areas of concern are the issues relating to the costs, risks, and benefits assessments. The main stages of the framework includes; definition of the problem, analysis of the potential environmental risks, assessments of specific anticipated legal, social, economic, political, and technological impacts, review of the key players (social, organisation and government) obligations, comparison of alternatives available, determination of accountability, implementation, decision making, monitoring and control processes.

Concepts and dimensionality in modeling unsaturated water flow and solute transport

Many environmental studies require accurate simulation of water and solute fluxes in the unsaturated zone. This paper evaluates one- and multi-dimensional approaches for soil water flow as well as different spreading mechanisms to model solute behavior at different scales. For quantification of soil water fluxes,Richards equation has become the standard. Although current numerical codes show perfect water balances, the calculated soil water fluxes in case of head boundary conditions may depend largely on the method used for spatial averaging of the hydraulic conductivity. Atmospheric boundary conditions, especially in the case of phreatic groundwater levels fluctuating above and below a soil surface, require sophisticated solutions to ensure convergence. Concepts for flow in soils with macro pores and unstable wetting fronts are still in development. One-dimensional flow models are formulated to work with lumped parameters in order to account for the soil heterogeneity and preferential flow. They can be used at temporal and spatial scales that are of interest to water managers and policymakers. Multi-dimensional flow models are hampered by data and computation requirements.Their main strength is detailed analysis of typical multi-dimensional flow problems, including soil heterogeneity and preferential flow. Three physically based solute-transport concepts have been proposed to describe solute spreading during unsaturated flow: The stochastic-convective model (SCM), the convection-dispersion equation (CDE), and the fraction aladvection-dispersion equation (FADE). A less physical concept is the continuous-time random-walk process (CTRW). Of these, the SCM and the CDE are well established, and their strengths and weaknesses are identified. The FADE and the CTRW are more recent,and only a tentative strength weakness opportunity threat (SWOT)analysis can be presented at this time. We discuss the effect of the number of dimensions in a numerical model and the spacing between model nodes on solute spreading and the values of the solute-spreading parameters. In order to meet the increasing complexity of environmental problems, two approaches of model combination are used: Model integration and model coupling. Amain drawback of model integration is the complexity of there sulting code. Model coupling requires a systematic physical domain and model communication analysis. The setup and maintenance of a hydrologic framework for model coupling requires substantial resources, but on the other hand, contributions can be made by many research groups.

People, places and public health : evaluating the benefits of civic environmentalism in an urban local government context

Recent political, economic and social trends pose threats to the sustainability both of ecosystems and of human health. Australia’s environmental management record is poor, and while by international standards Australians enjoy good health, this is variable (AIHW, 2000). Within developed nations, heart disease, depression, alcohol dependence and stroke are major health issues (Mathers et al. 2002). In Australia, mental disorder is the number one contributor to the disease burden (Vos & Mathers 2000). Recent research has highlighted the role of social capital as a key determinant of health (Kawachi et al., 1997). Despite this, Putnam (1995) observes that social connectedness and civic engagement are in decline. People have less time for leisure and for volunteering, as many juggle paid work and caring for children. Anecdotal evidence suggests that engagement in civic environmentalism has human health benefits, relating to a combination of exposure to natural environments and increased social capital (Maller, Brown, Townsend & St. Leger, 2002). This link is supported by Furnass (1996) who defines well-being as including: satisfactory human relationships, meaningful occupation, opportunities for contact with nature, creative expression, and making a positive contribution to human society. Research conducted by Deakin University confirms the efficacy of linking people and places through civic environmentalism for addressing both ecosystem sustainability and human health and wellbeing. The research has included a pilot study to explore the human health benefits of membership of a local parkland ‘Friends’ group, and a more detailed follow-up study. The aims of the pilot study included:- To identify the range of motivations for joining the Friends group;- To document members’ perceptions of the benefits gained from membership of the group;- To assess the potential for Friends groups to be used as an ‘upstream’ health promotion measure.Face-to-face interviews were conducted with eleven members of a ‘Friends’ group in the eastern suburbs of Melbourne. Data was analysed thematically and key findings included:- Motivations: environmental; social; and pragmatic.- General benefits: community belonging; personal satisfaction; learning opportunities; physical activity; and better environment.- Health benefits: physical health; mental health; and social support. There was unanimous support for the use of ‘Friends’ groups as a tool for health promotion.The follow-up study, in the western suburbs of Melbourne, expanded on the pilot study by measuring the group’s social capital and by collecting self-report data on levels of health service usage. Data was collected through face-to-face interviews and a questionnaire. The findings were similar to the pilot study in relation to the motivations, benefits and the health promotion potential of such groups. However, health service usage data highlighted an apparent anomaly: while respondents perceived significant health benefits, some were nevertheless utilising health services at a relatively high level. This poses some questions requiring further exploration: Is this due to the poorer baseline health of the high health service usage members compared with their fellow members? Does involvement in the group offer health benefits that enable people who would otherwise be too unhealthy to participate in community groups to continue such involvement?If this is the case, then we may do well to look to locally-based mechanisms for promoting ecological sustainability as a tool also for promoting human health. Instead of prescribing a pill, connecting people and places through engagement with a local friends group may address our health problems at the same time as addressing local environmental problems.

Energy production and use

The analysis and researches of many scholars and field specialists have gone into these 30 papers. They discuss many of the environmental problems and challenges to human life and existence presented by local and other exploitations and ongoing developments in Southeast Asian countries and marine areas. The authors use tabulated data and unpublished research in the eight sections on: underlying societal drivers and responses to environmental change; climate change and air quality; land transformation and its consequences; hydrology and hydrological cycles; changes in coastal and marine environments; vulnerabilities and adaptations to global environmental changes; and a final paper on a common need for action. This important volume includes reference, data, bibliographies and index.

Green revelations in a country of drought, flood and fire : a case study of Abrahamic faith communities and sustainability

This paper reports research into the levels of awareness and engagement of Abrahamic communities regarding environmental sustainability in the State of Victoria, Australia. Seventeen faith groups were targeted for study at 22 locations throughout Victoria and metropolitan Melbourne; with 15 in-depth interviews completed. The study suggests that personal awareness does not always translate well into group action, resulting in conflicting positions within denominations on how to respond to environmental issues. Some denominations have funding and human resources to support environmental programs. Smaller groups struggle to maintain numbers, are trying to expand, or do not participate because of fundamentally different worldviews.

The limitations and potentialities of green marketing

The authors evaluate the potential of green marketing and its limitations in solving society’s environmental problems. The streams of research in the green marketing area are reviewed and their assumptions and efficacies are discussed. While green marketing has some positive societal outcomes, on its own it is an insufficient solution to societal environmental problems in general and to humanity’s existential threat from climate change in particular. The authors analyze and discuss the roles and responsibilities of business, citizen-consumers, and government in contributing environmental solutions.

Use of indicators to assess the sustainability of housing developments in Australia

Most new housing in Australia is occurring on greenfield sites on the edges of the capital cities. These housing developments are often criticised for their social and environmental unsustainability. These unsustainable suburbs are a legacy for future generations. They will create dire social and environmental problems if a serious economic downturn was to occur or a resource shortage e.g. oil was to make accessibility impossible. Coupled to these threats is that of the social ‘undesirability’ of isolated suburbs where only those on low incomes made their home. Most of those on higher incomes seek established suburbs which have ‘character’, social amenities and ease of access. Typically, these are in older suburbs close to city centres. This paper describes a methodology that has been developed to analyse past and future housing developments. The results of the analysis can provide a guide to improving the sustainability of these suburbs. The methodology uses several criteria to reflect the fact that no single criterion is adequate to describe or analyse the sustainability of a housing development. Sustainability should embrace social and environmental perspectives, so a multi-criteria analysis is appropriate. The theoretical framework for this methodology has been described elsewhere. However, in this previous work only five criteria were considered: energy use, resource use, neighbourhood character, neighbourhood connectedness and social diversity. In each case, high and low sustainability practice has been identified so that ranking is possible. This paper initially summarizes the way in which these previous five criteria are assessed but then adds a sixth criterion (social connectedness) because of a perceived gap in the previous assessment. The results of an analysis of three suburbs reported in the previous work are updated. They score poorly in terms of social connectedness underlining the need to ‘repair’ these suburbs in order to improve their overall sustainability.

Challening the third sector global prospects for active citizenship

This is the first book to explore the different relationships between active citizenship and civil society, particularly the third sector within civil society. In what ways can the third sector nurture active citizenship? How have the third sector and active citizenship been constructed and reconstructed both locally and internationally, over recent years? To what extent have new kinds of social connectedness, changing forms of political engagement and increasingly complex social and environmental problems influenced civil society action? Written by experts in the field, this important book draws on a range of theory and empirical studies to explore these questions in different socio-political contexts and will be a useful resource for academics and students as well as practitioners.
