When Public Opposition Defeats Alternative Water Projects - the Case of Toowoomba Australia

Located approximately 100km west of Brisbane, Toowoomba is home to approximately 95,000 people. Surface water from dams is the main source of water for the city. In 2006 the residents of Toowoomba were invited to vote in a referendum (plebiscite) concerning whether or not an indirect potable wastewater reuse scheme should be constructed to supply additional water to the area. At that stage dam levels in Toowoomba were at approximately twenty percent of capacity. Toowoomba residents, after intense campaigning on both sides of the referendum debate, voted against the proposal. In July 2008 dam levels dropped to eleven percent. Stage 5 water restrictions have been in place since September 2006, subsequently mains water must not be used for any outdoor uses. This paper describes in detail how public opposition in the case of Toowoombas referendum, defeated the proposal for a water augmentation solution. Reasons for the failure are analysed. In so doing, the paper provides valuable insights with respect to public participation in indirect potable reuse proposals, and discusses factors including politics, vested interest and information manipulation. This paper is significant because of the lack of detailed information published about failed water infrastructure projects.

What affects public acceptance of recycled and desalinated water

This paper identifies factors that are associated with higher levels of public acceptance for recycled and desalinated water. For the first time, a wide range of hypothesized factors, both of socio-demographic and psychographic nature, are included simultaneously. The key results, based on a survey study of about 3000 respondents are that: (1) drivers of the stated likelihood of using desalinated water differ somewhat from drivers of the stated likelihood of using recycled water; (2) positive perceptions of, and knowledge about, the respective water source are key drivers for the stated likelihood of usage; and (3) awareness of water scarcity, as well as prior experience with using water from alternative sources, increases the stated likelihood of use. Practical recommendations for public policy makers, such as key messages to be communicated to the public, are derived.

Understanding behaviour to inform water supply management in developed nations - A review of literature, conceptual model and research agenda

Water is a scarce resource in many parts of the developed world. Two solutions are possible to address water scarcity: conservation of existing resources, or the further production of water from new sources e.g. through recycling of wastewater or desalination of seawater. However, the main hurdle to implementation of many of these solutions is often viewed as a lack of public willingness to adopt these alternative water behaviours. Research in this area is therefore crucial. Yet, and possibly due to the interdisciplinary nature of such research, there is currently no comprehensive overview of what has been done before. This study fills this gap by (1) choosing a general consumer behaviour perspective as a starting point, (2) developing a conceptual model of research required in the area of water-related public acceptance studies, (3) identifying eight key water-related behaviours which require future research attention, and (4) reviewing which areas of the conceptual model have been investigated in the past by conducting an extensive literature review of water-related social science research. The review established that the majority of work which has been conducted is located at the cross-roads of personal characteristics and behavioural intentions. Significant gaps exist in relation to researching the adoption of a wide range of demand-side water behaviours. This indicates a dominance of supply-side solutions in social-research exploration. The review identifies a number of research needs including: the exploration of actual adoption of water-related behaviours (rather than behavioural intentions); and to widen the scope of water behaviour enquiry to include more demand-side solutions. Given the increasing scarcity of water in many areas of the world, addressing these identified gaps will be of significant importance. Thus our model informs the social-research agenda for water policy.

The effect of information on public acceptance – The case of water from alternative sources

This study aims to provide conclusive evidence that information about water from alternative sources increases public acceptance. We conducted an experiment with 1000 Australian respondents asking them about their acceptance of recycled and desalinated water for a range of purposes under two conditions: 1) no information provided and 2) information about the production process provided. Results indicate that - both for desalinated and recycled water - the stated likelihood of use increases significantly if people are provided with information about the production process. This has major implications for public policy makers indicating that providing factual information (as opposed to persuasive campaigns) will increase public support of water augmentation projects.

Water conservation behavior in Australia.

Ensuring a nations long term water supply requires the use of both supply-sided approaches such as water augmentation through water recycling, and demand-sided approaches such as water conservation. Conservation behavior can only be increased if the key drivers of such behavior are understood. The aim of this study is to reveal the main drivers from a comprehensive pool of hypothesized factors. An empirical study was conducted with 3094 Australians. Data was analyzed using multivariate linear regression analysis and decision trees to determine which factors best predict self-reported water conservation behavior. Two key factors emerge: high level of pro-environmental behavior; and pro-actively seeking out information about water. A number of less influential factors are also revealed. Public communication strategy implications are derived.

Australians’ Water Conservation Behaviours and Attitudes

Abstract The Australian water crisis can be addressed in many ways, ranging from increasing water conservation behaviours to minimise demand, through to producing water through large-scale water augmentation projects. Due to the extended drought experienced in many locations across Australia in recent years, there has been a recent focus on developing wastewater recycling and seawater desalination plants. While this is an important measure for emergency water supply, water conservation should still play a major role in reducing demand for water. The aim of this study is to provide much-needed empirical data about Australian attitudes towards water conservation and their water conservation behaviours. This market insight provides a knowledge basis for the development of public policy measures and social marketing campaigns aimed at increasing water conservation among Australian residents. Results from a survey study of 1495 people indicates that Australians generally have very positive attitudes towards water conservation and water saving appliances, however, these positive attitudes are not consistently translated into actual behaviour. The main barriers to adoption of water conservation behaviours identified in the study are the perception of inconvenience and impracticality, as well as costs associated with purchasing water saving appliances. These findings highlight the fact that there is still substantial potential to be harvested in Australia though water conservation measures. Opportunities for public policy makers to stimulate this process are identified.

Newspaper coverage of water issues in Australia

The media has been found to have an impact on public debate, public opinion, and public policy agendas. Public debate, and public opinion about water conservation and water supply management projects matter because they can influence specific outcomes. For example, public opinion can potentially lead to positive behaviour, like increased water conservation, or potentially negative behaviours such as public opposition to developments such as dams or water recycling plants, which may be necessary under changing climatic conditions. It is therefore critical to understand how the media reports on water-related topics. Results from a content analysis of 1253 newspaper articles published in Australia in 2008 indicate that water-related reports are characterised by lack of inclusion of views held by various stakeholders, a low level of support of statements with scientific evidence, a low level of impartiality in the sense of reporting on opposing views and a relatively high level of hedging, meaning that the author signals that there is some uncertainly about the reported information. In sum these tendencies could theoretically culminate to work against public engagement in water issues and undermine the publics understanding of and confidence in water management measures. Proactive measures of media management are recommended.

Responding to environmental challenges: an initial assessment of higher education curricula needs by Australian planning professionals

Environmental planning education has become crucial given the projected implications of climate change for human settlements and nature. However, despite the identified importance of educating planners with regards to sustainability and environmental issues, there has been limited discussion of the topic within literature. In particular, there has been little consultation with planning professionals about their perception of environmental planning curricula needs. This article addresses this need through the survey of planning professionals in Australia. Perceived gaps in environmental knowledge and skills of planners were identified. The key knowledge gaps highlighted included climate change and water management. The key skill gaps highlighted included critical thinking and independent inquiry. Implications for urban planning curricula including the need to revise planning curricula are discussed. The study has implications for and interest to other professional degrees of which environmental sustainability is a component.

Does water context influence behaviour and attitudes to water conservation

Many rural and urban areas around the world are facing challenges to the supply of water. A key method of addressing water shortage is water conservation. The success of conservation measures depends on public support and behaviour change. While it is known that the public is generally supportive of water conservation measures, little is known about the dependence of water conservation attitudes and behaviour on geographical location and the water situation at specific locations. The present study investigates whether individual attitudes to water conservation, and reported participation in water conservation behaviours, differ between two Australian locations that vary significantly in their water situation. The first location, Darwin, is an urban location with a water surplus, whereas the second location, the Mallee in north-western Victoria, is a rural environment that has experienced an extended period of drought. Results indicate that there are significant differences in attitude and participation between the two areas. Significantly more people from the water-scarce location are supportive of most water conservation behaviours, and they are significantly more likely to state that they participate in water conservation behaviours. Implications for water policy are discussed.

Household use of and satisfaction with alternative water sources in Victoria Australia.

Climate change is increasing the variability of rainfall, and thus the availability of water supplies in many areas of the world. These impacts are already being felt in the state of Victoria, Australia where a 12 year drought period was recently experienced. Restrictions to water use have been implemented, as one component of a broad policy approach to manage the drought. While anecdotal evidence suggests that the substitution of centralised water supplies is occurring, this has not been proven empirically. This paper reports results from a survey of households in Victoria regarding their use of alternative water sources. The study found that substitution is occurring. Garden watering is the purpose which has the highest rate of alternative water source use. In total 41.6% of respondents always, and 33.2% sometimes use an alternative water source for garden watering. The most commonly used alternative source of water for garden watering is water previously used in the laundry (30.7%). The alternative source of water used was found to vary depending on the purpose of the water use. High levels of satisfaction were found for all alternative water sources used. Several barriers were found to the use of alternative water sources, the main of which were: inflexibility of existing infrastructure, cost, policy, and housing status. The results have implications for water retailers, policy makers and governments in locations facing water shortage.
