Environmental disaster education at the university level: an integrative approach

Because of the highly complex nature of chemical and nuclear accidents, efforts aimed at prevention, preparedness and response require the melding of many types of knowledge and the close collaboration of a wide range of professions. Nevertheless, the need for such integration and cooperation is not always strongly emphasized in university-level curricula. As a result, developing professionals have few opportunities to learn and practise unified models of environmental accident management. In an effort to foster a more integrative approach, the University of Alabama at Birmingham, USA, has launched the “Environmental Disasters” project. The project crosses disciplinary boundaries with respect to both curriculum and enrollment. In terms of curriculum, the project examines chemical and nuclear accidents from a multi-dimensional perspective, considering not only regulatory, scientific and policy issues, but also the public health, social, and psychological implications. In terms of enrollment, the project brings together students from the full range of fields that are involved with environmental accidents, including engineering, public health, public administration, social work, psychology, nursing, communications, medicine, and environmental studies. Emphasizing the need for a collaborative approach, students work in multi-disciplinary teams as they explore theory, case studies and current research. In addition, the student teams develop detailed plans for addressing the effects of a chemical or nuclear disaster. With environmental accidents representing an on-going threat to health and safety, the approach discussed in this article may provide a useful model for environmental disaster education at the university level.     

Environmental impact assessment of sprayed-on asbestos in buildings

This study evaluated the environmental impacts of sprayed-on asbestos, which had been used as insulation material in buildings, from multiple perspectives, mainly at the disposal stage. The health risks from asbestos emission and energy consumption were estimated. Two disposal scenarios were assumed for the asbestos: melting for reduced-risk disposal and ordinary packaging/landfilling. We estimated the asbestos emission and health risk in the case of packaging/landfilling, assuming uncontrolled management of the landfill site. A difficulty with introducing health-risk concepts into life cycle assessment (LCA) is the pulse–flux problem, which is discussed in the light of these estimations. In order to solve this problem, we proposed a method using a conversion factor representing exposure-dose/emission, and showed that emission could be converted into health risk. We also estimated the energy consumption for melting asbestos in the disposal stage, which can decrease the health risk. If we consider the energy consumption for the life cycle of asbestos, only a little energy is required for melting, compared with the large amount of energy saved in the use stage owing to the insulating effect of the asbestos. The trade-off relationship between health risk and energy consumption for the disposal scenarios indicated the need for weighting methods to handle trade-offs such as this.

Use of environmental teaching kits in Hong Kong

A systematic postal survey of 449 schools in Hong Kong (including kindergartens, primary and secondary schools) was conducted to investigate the use of environmental education teaching kits and to obtain feedback from teachers about the view and comments in using these kits. Results indicated that kindergartens used teaching kits more frequently than secondary and primary schools. Most of the schools found the existing teaching kits helpful. Appropriate content, updated information, attractiveness to students and inclusion of a teachers' guide were considered important criteria in deciding the use of the teaching kits. Good illustrations, quality production and appropriate duration for the class were considered important factors too. The tight teaching schedule was the major hindrance for secondary and primary schools in the use of the environmental teaching kits. However, the main hindrance for using environmental teaching kits in kindergartens was that they did not have sufficient copies. Hong Kong schools would like to see new teaching kits about waste recycling, energy conservation, green behaviour, air pollution, noise pollution, sewage treatment and wildlife endangering, focusing on Hong Kong and China.     

Is Gray Water the Key to Unlocking Water for Resource-Poor Areas of the Middle East,North Africa,and Other Arid Regions of the World?

Support for the use of treated gray water as an alternative water resource in the Middle East and North Africa is high, especially given the lack of religious restrictions against its use, but several obstacles have kept application of treated gray water near 1 % in some areas. The largest of obstacles include the cost of treatment and the ambiguity surrounding the health safety of gray water and treated gray water. This paper aims to provide an overview of current gray water practices globally, with specific focus on household-level gray water practices in the Middle East and North Africa region, and highlight the need for cost reduction strategies and epidemiological evidence on the use of household-level gray water and treated gray water. Such actions are likely to increase the application of treated gray water in water-deprived areas of the Middle East and North Africa.     

Climate change communication insights from cooperative Extension professionals in the US Southern states: finding common ground

Climate change is often avoided in educational programming due to its perceived polarizing nature. Identifying areas of agreement may help educators introduce climate change topics and help audiences begin to listen. As part of a survey of Extension professionals in the southeastern US, respondents shared their thoughts about climate change. Based on methods used by Maibach, Leiserowitz, Roser-Renouf, and Mertz [(2011). Identifying like-minded audiences for global warming public engagement campaigns: An audience segmentation analysis and tool development. PLoS ONE, 6(3), e17571], we categorized respondents using the Six Americas segments. Qualitative data analysis techniques were applied to identify common themes. Five themes emerged as common across most segments: (1) confusion and mistrust abound, (2) educators face barriers to climate change education, (3) economic aspects of climate change are important, (4) we should be good stewards of Earth, and (5) adaptation is an agreeable strategy. By identifying climate change message frames with which people may agree, regardless of how they feel about climate change, educators may be able to better communicate with broader audiences.     

Knowledge,agency and collective action as barriers to energy-saving behaviour

Energy saving is becoming a rising priority as a response to climate change and fossil fuel depletion in recent years. However, despite energy-related behaviour change being an important part of many environmental education initiatives, “energy literacy” among citizens remains patchy in both the USA and the UK, with evidence of strong positive attitudes but less consistent knowledge. Whilst it is clear that increasing knowledge does not automatically produce behaviour changes, potential questions must be asked about the logic of focusing solely on behaviour without simultaneously exploring and enhancing understanding of energy issues. This research, undertaken at a higher education institution with a strong focus on sustainability, illustrates the potential risks of targeting behaviour change and individual action at the expense of increasing knowledge, or encouraging collaborative and democratic endeavours. Results from an online survey indicate widespread misconceptions about energy which may reduce the effectiveness of energy-saving behaviours, alongside variable levels of motivation and engagement with energy issues. Respondents report a strong belief in the efficacy of personal changes, yet uncertainty about their capacity to influence business and government alongside a persistent faith in science to provide solutions to energy issues. The paper concludes by reflecting on the challenges arising from these findings for understanding agency and effectiveness in energy relationships.     

Seeing,believing, and behaving: Heterogeneous effects of an information intervention on household water treatment

Providing information about environmental health risks only sometimes induces protective action. This raises questions about whether and how risk information is understood and acted upon, and how responses vary across contexts. To characterize such variation, we stratified a randomized experiment related to household water quality across two periurban areas in Cambodia. When we showed specific evidence of water contamination to lower-SES households who were initially more optimistic about water safety, they altered their beliefs about health risk and increased their demand for a treatment product. However, demand for the treatment product among higher and initially more pessimistic SES households did not change significantly. These findings highlight the importance of better understanding heterogeneity in the specific drivers of responses to health risk information.     

Creating sense of community: The role of public space

A strong sense of community has been associated with improved wellbeing, increased feelings of safety and security, participation in community affairs and civic responsibility. Although interest in how the broader built environment influences sense of community is gaining momentum, there is a dearth of empirical research examining the association between sense of community and the quality of public space. This study investigates the relationship between four public spaces – Public Open Space (POS), community centres, schools and shops – and sense of community in residents of new housing developments in the Perth metropolitan area, Western Australia. Data was obtained from a cross-sectional survey (n = 911), a POS audit, and Geographical Information Systems, and analysed using linear regression. The perceived quality of neighbourhood POS and shops was significantly and positively associated with sense of community. This relationship appears to be unaffected by how frequently people use these spaces. High quality public spaces may be important settings for enhancing sense of community within residents of new housing developments.     

The role of parental behaviour for the development of behaviour specific environmental norms – The example of recycling and re-use behaviour

Based on the norm activation theory we developed assumptions about how parents may influence specific pro-environmental behaviours (i.e. re-use of paper and recycling) of their children (age 8–10). A sample of 206 parent-child-dyads were investigated using questionnaires recording norm activation model variables for children (i.e. awareness of need, awareness of consequences, personal norm, subjective norm, pro-environmental behaviour), as well as communication behaviour and actual behaviour of parents. For both behaviours (re-use and recycling) two separate structural equation models were tested (N = 206 and N = 194). Model fit statistics indicate a good fit of empirical data and model structure for both behaviours, supporting our assumption that the norm activation model can be applied to pro-environmental behaviour of young children. Communication behaviour of parents had a different influence on the two respective behaviours. While parents seemed to influence their children's recycling behaviour via sanctions and their own behaviour, re-use of paper was mainly influenced via communication of problem knowledge.     

Farming the battlefield: the meanings of war, cattle and soil in South Kivu, Democratic Republic of the Congo

Prior to 1996 and the Congolese wars, exploitative land policies pushed farmers in the eastern highlands of the Democratic Republic of the Congo (DRC) into a vulnerable position, with cattle manure sustaining intensive cultivation. This exposed households to a complete breakdown in mixed farming as cattle became targets of war. This study of villages in South Kivu offers an inside understanding of continuity and change in farming practices in a region where there are no easy solutions, and it assesses how the province lost its present and where farmers look when they glance to the future. For farmers, who hold a broad view of soil fertility, the casualties of war were not only people and cattle but also the land itself, which has enduring scars. Perceiving a rupture in tradition, South Kivu farmers are searching desperately for new livelihoods that are built on education instead of livestock, setting aside old ethnic signifiers to seek a future beyond protracted conflict.
