Influence of new town development on the urban heat island - The case of the Bundang area

Five new towns have been developed around the Seoul metropolitan area since 1996. However, these new towns generate lots of traffic and related problems in the areas including those new towns and Seoul as a result of increases in population and a lack of ecological-self-sufficiency. Currently, construction of another new town is under deliberation, and what should be a major consider is the notion that the new town be located within a wide, green zone. Many studies have revealed that green space can play an important role in improving urban eco-meteorological capability and air quality. In order to analyze the urban heat island which will be created by the new urban development, and to investigate the local thermal environment and its negative effects caused by a change of land use type and urbanization, Landsat TM images were used for extraction of urban surface temperature according to changes of land use over the last 15 years. These data are analyzed together with digital land use and topographic information. As a study result, it was found the urban heat island of the study area from 198.5 to 1999 rapidly developed which showed a difference of mean temperature above 2.0. Before the Bundang new town construction the temperature of the residential area was the same as a forest, but during the new town construction in 1991 analysis revealed the creation of an urban heat island. The temperature of a forest whose size is over 50% of the investigation area was lowest, and thus the presence of a forest is believed to have a direct cooling effect on the urban environment and its surroundings. The mean temperature of the residential and commercial areas in the study was found to be 4.5 higher than the forest, and therefore this part of land use is believed to be the main factor causing the temperature increase of the urban heat island.     

中国新克强指数的构建与实证分析

随着中国经济进入新常态,英国《经济学人》杂志构建的克强指数已无法反映中国经济的全貌,如何客观地反映中国经济的真实状况成为一个迫切需要解决的现实问题。为更好地测度中国经济运行的真实状况,本文根据李克强总理提出的"未来会更加关注就业、居民收入和生态环境的持续改善"的愿景,在原有克强指数的基础上,增加年末就业人员数、农村居民家庭人均纯收入、城镇居民家庭人均可支配收入等就业和收入方面的指标,使用中国1995—2015年的相关数据和层次分析法构建了克强指数的修订版本即新克强指数,并将新克强指数与GDP增长率、克强指数进行了比较,发现新克强指数在反映中国经济波动和经济整体运行状态上有更为优良的性质。与GDP增长率相比,新克强指数克服了服务业比重提高带来的熨平效应,进而灵敏地反映中国经济波动情况,并对异常事件更加具有敏感性。相对于克强指数而言,新克强指数破除了因中国在第二产业上存在失衡性发展所带来的经济波动的杠杆效应,降低了经济增长中的虚假成分,从而与中国经济运行的整体关联度更为密切。此外,相对于克强指数而言,新克强指数在反映经济景气方面有着较好的时效性与关联性。采用时差相关分析法对新克强指数与宏观经济指标之间的关系进行分析,发现新克强指数在反映第一产业增加值、第三产业增加值、最终消费支出、资本形成总额、对外贸易、通货膨胀等方面具有优势。研究表明:新克强指数是更适宜测度中国经济的多元评价指标,为测度中国经济运行的真实状况提供了科学的参考依据。     

The community vs. the market and the state: Forest use inUttarakhand in the Indian Himalayas

Most writers on resource management presume that local populations, if they act in their self-interest, seldom conserve or protect natural resources without external intervention or privatization. Using the example of forest management by villagers in the Indian Himalayas, this paper argues that rural populations can often use resources sustainably and successfully, even under assumptions of self-interested rationality. Under a set of specified social and environmental conditions, conditions that prevail in large areas of the Himalayas and may also exist in other mountain regions, community institutions are more efficient in managing resources than either private individuals or the central government. In advancing this argument, the paper undermines the often dogmatic belief in the universal superiority of private forms of ownership and management.

Emerging dynamics of environmental governance in northern post-productivist regions

The northern, resource-dependent regions of Canada have long faced distinctive social, economic, and environmental challenges and vulnerabilities. However, these regions and communities increasingly find themselves in a transitional and post-productivist context – the implications of which are largely unclear. Therefore, research is needed to identify the current and emerging challenges facing such regions and how environmental governance and planning must adjust to meet these challenges. We utilise the case study of the Northeast Superior region of Ontario to identify and analyse the dynamics developing in post-productivist, resource-dependent regions and what the implications may be for environmental governance. Several key themes and issues that emerged include an increasingly pluralistic context, new regionalism and north–south tensions, First Nation initiatives and power imbalances, and northern identities which are tied to ideas of historical resource-dependence, remoteness, and intimate and complex links to the landscape, all of which inform environmental governance and sustainability debates. As a result, the Northeast Superior case provides insight into these ongoing dynamics which encompass individuals, government, industry, organisations, and the landscape, with the resultant lessons being transferable to initiatives in other northern, remote, and circumpolar regions.
