Without improved water resource management, it is predicted that water shortages will affect two‐thirds of humanity by 2025. One solution that has traditionally faced fierce public resistance is recycled waste water. This study investigates the extent to which public communication strategies can influence community acceptance of recycled water, using the framework of Inoculation Theory. A four‐phase experimental design was conducted. Participants completed an initial questionnaire and were then randomly assigned to a control group, a manipulation check group or a treatment group. A final follow‐up survey measured changes in the dependent variable: stated likelihood of using recycled water for different uses. Results indicate that communication strategies based on Inoculation Theory are limited in their effectiveness for this product category. Findings do, however, identify a clear recency effect, indicating that continuous public communications are key to ensuring that community scare campaigns do not prevent implementation of water augmentation projects. This study differs from previous applications of Inoculation Theory because of the challenges associated with marketing a monopoly commodity, which is a necessity to support life. This empirical study uses fictional marketing stimuli to test the theory in a context, which is growing in global importance. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

论文基于利益博弈分析,论证了水环境治理有必要强化政府管制,单纯的市场机制和自主治理都不具有可持续性;与"自下而上"或"自上而下"机制相比较,政府主导型综合治理机制在效率和降低交易成本上更具有优势。近年来,云南滇池治理取得积极进展的经验表明,建立政府主导型综合性治理机制对提升水环境治理成效具有显著贡献。  相似文献

水域污染的社会学解释——东村个案研究   总被引:3,自引:0,他引:3  
本文选择太湖流域的东村进行田野调查 ,发现 ,传统社会水域保持清洁的原因是 :农业社会长期形成的生产、生活方式有利于圩田系统的生态平衡 ,并且 ,村落的社会规范及村民的道德意识也有效地约束了村民的水污染行动。 90年代以来 ,东村及其周围水域被迅速污染。水域污染问题主要不是科学技术问题 ,而是经济社会问题。利益主体力量的失衡、农村基层组织的行政化与村民自组织的消亡以及农村社区传统伦理规范的丧失是造成水域污染的主要原因。与市场经济体系相适应的法律制度建设是解决水污染问题的根本途径  相似文献

Given the myriad of policy instruments aimed at enhancing water quantity conservation available to municipalities, what drives them to opt for a market-based instrument (MBI)? MBIs can be effective and efficient policy instruments to enhance water quantity conservation, but there is little known about why municipalities utilize them. This study hypothesizes that three contextual elements influence a municipality's use of an MBI: the natural, political, and structural environment. The results from two logistic regression models suggest that in a municipality suffering a higher drought level, both a conservative political environment and operating under a council-manager form of government (with the effect more pronounced under a non-council-manager form) will increase the likelihood that it will use an MBI to address water conservation.  相似文献

Agrarian adaptations in Tajikistan: land reform,water and law   总被引:1,自引:0,他引:1  
In Central Asia, agriculture and water management have ranked as the two most important economic activities in this arid environment. These activities gained even more prominence during the Soviet era as planners expanded irrigation into previously marginal land that bolstered their vision that the best land be allocated exclusively for cotton production. In the wake of the fall of the Soviet Union, Tajikistan has enacted laws meant to expand and clarify land use categories to meet the dual targets of expanding food production within the country while maintaining as much land as possible in cotton production – their economic mainstay. To this end, the Tajik government instituted five categories of land tenure. Though comprehensive, these new dispositions merely mask a continuation of top-down agrarian decision making implemented during the Soviet period. Consequently, this change has created new problems for farm labourers as they struggle to adapt to post-Soviet life and negotiate with the new bureaucracy in the face of ‘de-modernization’ and the loss of jobs, wages, and in many cases, access to productive land. This research demonstrates that the means by which the Tajik government expanded food production has contributed to agricultural problems apparent at the time of independence.  相似文献

Human geolocation is prefaced on the accuracy of the geographic precision of mapped isotopic values for drinking water. As most people live in cities, it becomes important to understand city water supplies and how the isotopic values uniquely reflect that city. This study investigated the isotopic distribution of δ2H and δ18O from sourced tap waters that were collected from across the Metro Vancouver (MV) area (n = 135). The results revealed that the isotopic values reflect their water sources with a range of 5.3‰ for δ18Otap and 29.3‰ for δ2Htap for MV. The results indicate that individual cities need higher resolution studies to determine their tap water isotopic ranges, and a good understanding of the water supply network itself for human geolocation work. With an extended high‐resolution understanding of each city, human tissue may be compared with more certainty for geolocation.  相似文献
