日本的城市环境问题及其改善过程：政策和规划视角研究

日本是亚洲最先城市化的国家,目前已有86%的人口生活在城市行政区范围内。在城市化的进程中,日本曾出现过各种各样的环境问题,经过半个多世纪的努力,现在的城市生活环境不仅得到根本改善,而且在资源循环利用和低碳社会建设等方面也做出引人注目的成绩。本文从日本城市规划制度和环境政策演变角度,分阶段介绍自1950年以来的城市环境问题、环境法律和有关城市规划建设的政策,逐步展开日本改善城市生活环境、保护地球自然环境的过程,尤其注重从生态城市到低碳社会转型发展的最近政策动向。     

Wistful wilderness: communication about ‘new’ nature in the Netherlands

Based on in-depth interviews, this article presents findings of a study centred on public communication regarding Tiengemeten, a Dutch island previously occupied by farmers. An answer is sought to the question of how visitors to Tiengemeten evaluate, according to their own experiences, the discourse of people involved in Tiengemeten from a policy and communication perspective. This study showed that visitors’ experiences do not always match the emotions appealed to in public communication materials. It is also suggested that people involved from a policy and communication perspective should refrain from using ‘heavily value-laden’ phraseology. For reasons of trust, this article suggests aligning public communication with genuine experiences of visitors. This is also necessary for avoiding scepticism of visitors as policy makers and communication professionals run a risk that public communication regarding nature becomes counterproductive.     

Science–policy interactions in Austrian,Dutch, and Swiss climate policy: a comparative account

Scientific expertise plays an important role in the complex field of climate policy. Consequently, science–policy interactions have been institutionalized in many countries. However, science–policy arenas vary considerably across countries. Scholars mainly attribute these differences to the influence of specific political cultures. The literature has primarily compared science–policy arenas of countries with diverging political cultures, whereas comparisons of countries with similar political cultures are rare. The latter is especially true for neo-corporatist cultures. Against this background, we compare the climate science–policy arenas of three neo-corporatist countries, Austria, the Netherlands, and Switzerland. Conceptually, we draw on the literature regarding politico-cultural imprints in science–policy arenas. We operationalize national science–policy arenas along four dimensions: the knowledge actors, the organizational formats, the styles of science–policy interactions, and their transparency and visibility. Overall, the three arenas reveal many similarities and much fewer differences. Most similarities correspond to neo-corporatist patterns. However, some similarities consistently deviate from neo-corporatist patterns. Interestingly, almost all differences between the countries match national variations of neo-corporatism. In light of these observations and the specific problem structure of climate policy, we develop research questions to investigate potential explanations for correspondence to and deviation from neo-corporatist patterns.     

Wind energy potential analysis for Thailand: Uncertainty from wind maps and sensitivity to turbine technology

Rapid development of wind energy has been witnessed in Thailand. However, different wind resource maps (over land) have brought great uncertainty to wind energy planning. Here, four important mesoscale wind maps were considered: DEDP (2001), World Bank (2001), Manomaiphiboon et al. (2010) of JGSEE, and DEDE (2010). The wind maps were first harmonized to a common grid at 100 m and then compared. The earlier wind maps (DEDP and World Bank) are shown to represent the lower and upper limits of predicted speed, respectively, while JGSEE and DEDE tend to be more moderate with predictions statistically closer to observations. A consolidated wind map was constructed based on their median and shown to have the best prediction performance. It was then used for the technical potential analysis, in which three large (2-MW) turbine models (two conventional and one designed for low wind speed) were considered. By GIS techniques, any land areas not feasible for large wind turbines were excluded, and the corresponding overall onshore technical potential ranges between 50 and 250 GW, depending on map and turbine model. Considering only economically feasible turbines (with capacity factors of 20%) and the median-based map, the final technical potential equals 17 GW when using the low-wind-speed model but is reduced to 5 GW with the conventional models, adequately meeting the national wind energy target of 3 GW by the year 2036. The results suggest a strong sensitivity of estimated technical potential to turbine technology and a suitability of low-wind-speed turbines for wind conditions in Thailand.     

大气排污交易政策实施的技术原则

排污交易政策由泡泡政策、补偿政策、净得政策及排污量存储政策组成。现阶段我国实施大气排污交易政策主要在同一厂区“以新带老”、排污补偿及可用购买盈余排污量来达到排放标准三方面进行;还论述了排污交易量、排污交易费用确定的原则。

Disaster risk, climate change and international development: scope for, and challenges to, integration

Reducing losses to weather-related disasters, meeting the Millennium Development Goals and wider human development objectives, and implementing a successful response to climate change are aims that can only be accomplished if they are undertaken in an integrated manner. Currently, policy responses to address each of these independently may be redundant or, at worst, conflicting. We believe that this conflict can be attributed primarily to a lack of interaction and institutional overlap among the three communities of practice. Differences in language, method and political relevance may also contribute to the intellectual divide. Thus, this paper seeks to review the theoretical and policy linkages among disaster risk reduction, climate change and development. It finds that not only does action within one realm affect capacity for action in the others, but also that there is much that can be learnt and shared between realms in order to ensure a move towards a path of integrated and more sustainable development.     

智慧城市试点政策对城市安全水平的影响研究——基于区域异质性的视角

为探究新的城市管理模式(即智慧城市政策)对城市安全水平的影响,采用我国国内(不含港澳台,下同)156个地级市2007—2019年间的面板数据,结合双重差分法进行评估,利用双重差分倾向得分匹配法(PSM-DID)进一步验证,探讨区域异质性视角下智慧城市试点政策对城市安全水平的影响。研究结果表明：智慧城市试点政策的实施对城市安全水平具有显著的正向促进作用;在控制地区层面因素及各固定效应后,结果证明随着政策实施时间的推移正向促进作用逐渐增强;异质性分析结果表明智慧城市政策对特大型城市及东部地区城市影响较为显著,对非省会城市影响显著大于省会城市。
