An Assessment of People's Satisfaction with the Public Hearing on the Yadana Natural Gas Pipeline Project

Many public and large-scale construction projects inThailand have been faced with environmental and socialconflict problems. The major cause is that project sponsorsdo not address concerns of the public in a proper mannerduring EIA study. The Yadana Natural Gas Pipeline (YNGP)project is an example of a project which suffered theeffects of public demonstration. A public hearing, onetechnique of public participation, is a good mechanism tosolve conflict problems in a non-violent way which the ThaiGovernment usually adopts to settle conflict in constructionprojects. In the case of the YNGP, even after the conflictwas resolved hostility towards the project was noteliminated, as the opponents were not satisfied with thedecision. Therefore, this article examines the hearing on theYNGP project. The study found that it was too late to make any significantchanges to the project after the hearing was held, mostrespondents were not satisfied with the project. In otherwords, this hearing did not improve their perception ofenvironmental soundness of the project. The study showedthat the project's impact on the environment was notproperly addressed. The project sponsors did not providesufficient publicity for the meeting and the stage at whichthe hearing was conducted. Suggestions are made forimproving participation in future hearings.     

An Italian Study on Cryptosporidium and Giardia in Wastewater, Fresh Water and Treated Water

Cryptosporidium oocysts and Giardia cysts has been isolated from waters worldwide. In Italy, studies on these parasites in the environment are still limited due to absence of epidemiological evidence and difficulty of adequate methodologies of sampling and analysis. The new Drinking Water Directive 98/83/CE states that Cryptosporidium has to be determined in water intended for human consumption if Clostridium perfringens is detected. This investigation contributes to the knowledge of both Cryptosporidium and Giardia occurrences in Italian aquatic environments through a two-year monitoring program. In addition, indicator bacteria and Clostridium perfringens were monitored in sewage, surface waters, drinking water, and swimming pools and possible correlations were calculated among all the selected parameters. Cysts and oocysts were detected in sewage and surface water and Giardia numbers always prevailed over Cryptosporidium. The parasites were not detected in drinking water, while a positive sample was obtained from the analysis of swimming pools. Pearsons correlation coefficients evidenced a reciprocal correlation between both the protozoa and the Enterococci counts.     

基于Windows DEA模型的我国自然灾害应急公共投入绩效研究

为提升自然灾害应急公共投入绩效评价的精准性、科学性,运用动态绩效评价Windows DEA模型,结合应急处置结果,对我国近年来自然灾害领域的应急公共投入绩效进行全面系统评价,研究结果表明:我国应急公共投入效率不高且有较大改善空间;应急公共投入效率较高的省（区、市）未能产生辐射效应;我国应急公共投入效率呈现“滞后性”,即当年投入的应急公共投入在当年未得到相应产出。     

基于水库旱限水位动态控制的供水策略研究

为了克服现行水库旱限水位确定方法和功能定位上存在的不足,更好地为水库抗旱调度提供技术支持,通过结合供水系统水文干旱识别方法,用汛末蓄水量、干旱期设计来水量及供水规则计算干旱预警期。并根据实际来水逐月修改来水系列,对当年潜在干旱期和干旱预警期进行再计算,实现旱限水位的动态控制,由此提出了用“预警期/旱限水位”数对的形式(Td,DL)来表示的旱限水位动态控制方法。将旱限水位与限制供水策略相关联,用水库旱限水位作为触发水库限制供水的特征水位。并以水库累计缺水指数最小为目标,以限制供水系数为优化变量,建立水库进入干旱预警后的供水模拟-优化模型。以天津市于桥水库为实例研究,结果表明,旱限水位动态控制方法对水库干旱的预警不仅更加合理,且具有较好的可操作性;旱限水位与限制供水策略相关联,避免了潜在干旱期内水库出现程度更加严重的缺水,对不同蓄水条件下的限制供水系数进行分析,发现限制供水系数最优值一般取在0.5~0.75。     

The acceptability of wind farms: the impact of public participation

The planning process for wind farm projects appears to be a complicated matter in many cases. Despite the positive attitude towards wind power in general, local wind farm projects often face strong opposition. The aim of this study is to shed more light on residents’ perceptions of participation in the planning process of wind farms. This study is based on interview data (N?=?22) and survey data (N?=?291) collected from residents living near two Finnish large-scale onshore wind farms built about 1.5 years before the data were collected. The results indicate that residents’ participation in the planning process was rather passive and the vast majority of the respondents perceived that they did not have an opportunity to participate. Quite interestingly, perceived participation in the planning process resulted in a decrease in acceptability in terms of perceived well-being. Furthermore, the results indicate that the need for participation does not expire after the planning process for a wind farm has concluded. Thus, project developers should be prepared to continue communication with residents after the planning phase.     

A ‘delivery-democracy dilemma’? Mapping and explaining policy change for public engagement with energy infrastructure

Understanding how governments orchestrate public engagement in energy infrastructure decisions has important implications for the relationship between energy transitions, democracy and justice, but existing research is deficient in focusing mainly on single case studies. In response, we conduct a multi-sectoral, comparative analysis for the first time to assess how UK governments have engaged publics, applying a novel mapping methodology that is systematic, longitudinal and cross-technology. Moreover, our focus embraces mechanisms of consultation and support measures (e.g. community benefits) and seeks to explain patterns of change using a pragmatist sociology framework. Findings indicate trends towards a reduced scope for public engagement alongside expanded encouragement of community benefits, but also important sectoral differences. On-shore wind moved towards giving local decision-makers significant control over decisions. Gas-fired power stations experienced continuity, with central government controlling consents and limited interest in community benefits. Fracking facilities received intense promotion of community benefits, alongside incremental moves to restrict local decision-making. We argue that the patterns observed reflect government beliefs about the scope for depoliticisation in concrete situations, in which the conjunction of technologies, sites and publics affects how and whether arrangements for public engagement change. These results raise challenges for how researchers seek to connect energy transitions and democracy.     

Making the sustainable more sustainable: public transport and the collaborative spaces of policy translation

This paper investigates where and how sustainable transport goals are translated into public transport planning and operations. The case where this is explored is the Regional Public Transport Authority (RPTA) in Stockholm, Sweden. By drawing upon recent discussions on policy translation and political–administrative relationships, sustainable transport is found to be translated in two different collaborative spaces in the RTPA. In the market side of the authority, which is mainly preoccupied with procurement of traffic and compliance issues, sustainable transport is translated into quantitative goals (including biofuels, emissions, noise, etc.) and mechanically reproduced from the politicians via the civil servants to the private operators. In the planning side of the authority, sustainability measurements have been hard to quantify and the challenge to integrate land-use and transport planning is resolved in an organic manner, in specific projects, between the strategic transport planners in the RPTA and the land-use planners in the municipalities, at a distance from the politicians’ involvement. Throughout the RPTA, sustainable transport has broadened to also include social sustainability, although this has been difficult to translate into quantitative measurements, which is the desired mode of governance by the politicians.     

Picking up speed: public participation and local sustainability plan implementation

Although planning scholars often argue that public participation improves implementation outcomes, this relationship is rarely empirically tested. This study investigates how public engagement, during planning and after plan adoption, impacts on the speed of local government sustainability plan implementation. It includes a correlation analysis of quantized in-depth interviews with sustainability planners in 36 American cities. The study finds that individual characteristics of public engagement, both during planning and after plan adoption, had statistically significant relationships to implementation speed, but in some cases this relationship was negative. The correlations imply that sustainability planners can make strategic choices to improve implementation speed through public participation in plan creation and after plan adoption. Alternatively, planners also make choices during participatory planning that slow implementation, a problematic outcome when the ultimate goal of a planning process is on-the-ground change.     

Analyzing social perception as a key factor in the management of protected areas: the case of the Sierra Nevada Protected Area (S Spain)

Protected areas cannot be considered as elements isolated from the human groups that inhabit them. Consideration of the social factor is fundamental to guarantee the success of any management model. In this sense, analyzing the perception of people who live in protected areas can be a key tool for the formulation of proposals for improving the existing models. This article explores perceptions of local residents in the Sierra Nevada Protected Area in Southern Spain and identifies the socio-demographic factors that affect these perceptions. The main objective is to generate relevant data for the protected area management team. The recommendations we can offer entail a review of the communication plan and participatory strategy considering social differences in perceptions of the local population.
