ST is undeniably considered as one of the most significant parameters to assess the impact of temperature variability in any urban environment. The present work tries to extend the work beyond the thermal image processing for variability analysis with a multiscale cell division approach. Subsequently, a radical approach in conjunction with formal statistical techniques is attempted to characterize the spatial variability for the directional attributes. These methods may be helpful in detecting and quantifying the spatial variability at major and minor scales. The spatial variability is investigated to illustrate the spatial distribution of temperature over urban–rural (Rurban) areas contributing to the heat island. The results seemingly revealed that there is an aggregation of the spatial thermal gradient along Rurban areas and vice versa, whereas urban fringe exhibited very complex results of temperature variability for the various land use. The study also validated the approaches for integration of spatial variability techniques with the formal statistical approach as a reliable mechanism to monitor the thermal dynamics in the urban environment.","PeriodicalId":44260,"journal":{"name":"Asian Geographer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10225706.2017.1322992","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46118499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we developed one tree-ring-width chronology of Tsuga dumosa (D. Don Eichler) in the Gaoligong Mountains, southeastern Tibetan Plateau. Tree-ring-width chronology showed negative correlations with monthly temperatures in most months, especially for current year, whereas correlations with precipitation and relative humidity were mostly positive. Significant positive correlations were found between tree rings and relative humidity in February, April and June of current year and May of previous year. February–April relative humidity was reconstructed for the past 321 years (A.D. 1695–2016) in the Gaoligong Mountains, which explained 26% of the actual variance during the calibration period 1962–2004. In this reconstruction, dry periods occurred in 1808–1820, 1831–1842, 1914–1921, 1958–1964 and 1980–1988. Wet periods were found in 1700–1727, 1821–1830, 1843–1859, 1944–1957 and 1965–1979. The dry and wet episodes of our relative humidity reconstruction match well other studies in the nearby regions, which demonstrate that the new record is reliable and captures large-scale climate signals.","PeriodicalId":44260,"journal":{"name":"Asian Geographer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10225706.2017.1325758","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47539076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the regime becomes less authoritarian and more pluralized, a multitude of stakeholders (both state and non-state), are now involved in promoting, constructing, challenging and safeguarding a variety of meanings and values in heritage. This paper focuses the attention on the market sector and examines the extent of market forces in contributing to effective heritage conservation using the designated historic district of Xinhepu in the old residential district of Yuexiu in Guangzhou as a case. The concept of neoliberalism implies a larger role played by the market, which is defined as investment, expertise and innovations from the private operators. Informed by a review of relevant documents and publications, and semi-structured interviews with Guangzhou-based state- and non-stakeholders who have extensive knowledge on managing the historic district, this paper examines the achievements and difficulties of individual private operators face in protecting heritage buildings and historic buildings on the site. The findings suggest that Guangzhou has yet to fully embrace a neoliberal approach to heritage conservation. The conditions of extending market forces to successfully conserve the entire historic district include the formulation of a clear set of regulatory rules and the presence of implementing agencies with enhanced institutional and organizational strength, both of which are regrettably absent in the case.","PeriodicalId":44260,"journal":{"name":"Asian Geographer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10225706.2016.1250645","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59942385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It explores how a group of Republican Chinese geographers, such as Zhu Kezhen 竺可楨 (1890–1974), Hu Huanyong 胡煥庸 (1901–1998), and Zhang Qiyun張其昀 (1900–1985), reexamined Chinese traditional dynastic geography (yange dili) and defined the nature and methodology of what they called the “new geography” under the context of foreign imperialism, Chinese nationalism, and escalating frontier crisis. It argues that Chinese intellectuals’ efforts to overcome the frontier crisis led to a significant shift of major methodology in geography from textual research to actual fieldwork or on-site investigation. The adoption of this new methodology distinguished the “new geography” from the old dynastic geography. Geographers also grappled with multiple concepts and diverse traditions in physical geography, human geography and regional geography. Environmental determinism was adopted but quickly replaced by possibilist approaches. There were also attempts at reforming the traditional Chinese gazetteers using modern geographic ideas. Geographical research was imbued with political concerns. Cooperation between geographers and the state also led to the establishment of important geographical departments and study societies, providing institutional foundation for the maturation of modern Chinese geography as a discipline independent of either history or geology.","PeriodicalId":44260,"journal":{"name":"Asian Geographer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10225706.2016.1252274","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59942389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The earthquake took the lives of about 9000 people, injured about 24,000 and affected one-third of Nepal’s total population (28 million). Despite a huge amount of money (US$ 4.4 billion) pledged by the international community, reconstruction works could not take place on time. Using participatory approach to reconstruction and development as a theoretical framework and reflexivity as a methodological tool, this paper argues that the delay in reconstruction was caused by the inability of the Government of Nepal (GON) as well as the international community, mainly donors, to encourage local participation. The amount of loan pledged by the international community has increased Nepal’s debt stock rather than really helping those who are affected by the disaster. The paper concludes that the modernist top-down model of development – that both government and donors take for granted – has created roadblocks towards understanding Nepal’s contextual realities. Sustainable reconstruction and development cannot be achieved without strengthening the capability of local communities.","PeriodicalId":44260,"journal":{"name":"Asian Geographer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10225706.2016.1235053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59942335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The river bank communities such as Chapra encounter exclusion because of geographic aspects of local water development projects. To understand this exclusion, this paper focuses on the research question; why did the Ganges-Kobodak and the Gorai River Restoration Projects cover some parts of Chapra and ignore others? This question is addressed here by using participatory mapping based on qualitative and quantitative data analyses in coordination with cartographic knowledge. For these data, I use my Ph.D. fieldwork experiences in 2011–2012 on the Gorai River bank communities at Chapra in Bangladesh. My data analyses found that the projects’ boundary selection follows the top-down approach that includes some specific geographic areas and excludes others based on specific interests. To understand the effects of this approach on Chapra communities and to promote community participation, this paper is divided into three major sections: participatory mapping in the context of my fieldwork site, bottom-up mapping approach as foundation for community inclusion, and participatory mapping for community empowerment: local development and resource conservation. These sections will be helpful for responding the above research question and for developing better understanding about community empowerment by participatory mapping approach.","PeriodicalId":44260,"journal":{"name":"Asian Geographer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10225706.2016.1237370","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59942352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study focused on the historical district of Kuala Lumpur, Malaysia. Data were gathered from questionnaire survey conducted with 330 respondents, who were tourists walking in the area. The study demonstrated that tourists’ expectations on the spatial characteristics of walkways in terms of accessibility, connectivity and continuity were greater than their satisfaction. The tourists’ satisfaction relates strongly to diverse street usages and activities.
