Spatial practices and imaginaries: Experiences of colonial officers and development professionals

This paper explores the spatiality of colonial and postcolonial power and discourse as produced, performed and imagined by former British colonial service officers and contemporary UK international development professionals. It focuses on two key aspects of spatial practices. The first addresses the spaces inhabited by these colonial officers and development professionals overseas and how their locatedness, embedded or enclavic, shapes relationships to others. The second explores this distinctive social and spatial distancing through their relationship to, and imagined geographies of, home and away and how these are embodied in their institutional and cultural capital. The paper examines the regularities and consistencies that stand out from numerous individual practices through which both former colonial officers and development professionals negotiate the situations in which they live and work. It also specifies how authoritative management, privilege and distance informs their spatial practices despite changing global contexts and a more diverse composition of those who articulate contemporary relationships between 'first' and 'third' worlds. Finally, the paper suggests that the cultures which travelled over colonial space through being performed by colonial officers have been reworked throughout the postcolonial period, belying epochal historical periodizations that conjure up a clear disjuncture between colonial and development eras.     

Towards a method for postcolonial development geography? Possibilities and challenges

In this paper we explore the contours of a 'method' for postcolonial development geography, which makes it possible to imagine another 'world-picturing'. We suggest three steps towards such a method. First, we propose that a postcolonial method involves thinking about why we are doing research in the south in the first place; how we come to and produce our questions; and how we analyze and represent our findings based on our subject positionings. Second, that we need to recognize theorization as an inherent part of method, rethink how we currently theorize and reconfigure our methods of theorization to address wider political aims. Problematizing theorization helps challenge the universalism of Eurocentric theories, thus enabling development geography to move towards more decolonized versions and visions. Finally, that this must be accompanied by firmer recognition of our multiple investments – personal, institutional and geopolitical – and how they frame the possibilities for change. These are some possible steps that we think can reconfigure the 'scholarly track' that postcolonial development geographers traverse.     

秦皇岛市矿产开发引发的地质环境问题及对策

秦皇岛市矿产资源丰富,矿业已成为秦皇岛市特别是地方经济的支柱之一。伴随着矿业的发展,在矿产开发过程中引发的地质环境问题日益突出,如采空区地表变形(地面塌陷、地裂缝等)、岩溶塌陷、露天采矿边坡失稳、尾矿引发的泥石流、水土流失以及地貌景观的破坏等。这些地质环境问题主要分布在北部的山区和丘陵台地区。形成的原因复杂,主要有法制不健全、缺乏强制恢复机制、布局不合理、监管不到位、开采技术落后、不合理开采、资金缺乏以及从业者环保意识淡薄等方面的原因。对于矿山地质环境的保护,应采取加强立法、建立保证金制度、统一规划、加强监管、加大宣传力度以及建立责任追究制度等措施。     

四川省康定县滑坡灾害发育特征与形成条件

康定县地处四川盆地西缘山地及青藏高原过渡地带。县域内地势险峻,地形切割强烈,地层与地质构造复杂,新构造运动强烈,地震活动频繁。加之降水充沛,致使山地灾害十分发育,其中滑坡灾害占山地灾害的38.32%。通过搜集资料及现场调查,概述了该县县域内滑坡灾害的分布;从行政区划、自然地理及灾害规模等3方面统计分析了滑坡灾害的发育现状;从地形地貌、地层岩性、地质构造、降雨、地震活动、人类工程活动等方面总结了滑坡灾害的形成条件,并提出防治对策与措施,力求有效地预防与减少滑坡灾害的发生。     

河北省邯邢东部平原区（冀南凹陷）地热资源的利用与开发

邯邢东部平原区温增温率3℃／100m，被任为是不宜开采利用的“非地热异常区”。但近几年来在该区已成功施工了井深1500～1800m的探采结合地热井拾余口，井口出水温度达50℃以上，证实了邯邢东部平原区地热开发利用前景广阔。根据该区域地热条件背景及地热资源赋存特点，结合该区近几年地热探采施工体会，对地热井成井工艺和合理开发利用地热资源的提出了有益见解，对类似平原区地热资源的开发利用具有一定的启发和借鉴意义。     

Gated communities of the Moscow green belt: newly segregated landscapes and the suburban Russian environment

The transition from the Soviet to the post-Soviet period in and near Moscow manifested itself in increasing production of segregated space both in the urban core and suburban areas outside of the beltway to accommodate the preferences of the new Russian business and governmental elite. This paper focuses on the residential single-family housing inside old and new settlements, which are frequently gated. Approximately 260 of such suburban communities have been developed within 30 km of the beltway during the past few years, of which a majority have some form of exclusion mechanism in place, typically tall solid fences, gates, closed-circuit video surveillance and guarded entry checkpoints. The difference in exclusivity varies from the most exclusive older communities inside Moscow Serebryany Bor enclave and Rublevskoe highway mansions to less exclusive new developments along Novorizkhskoe and Dmitrovskoe highways. Despite high rates of construction, based on sociological surveys in 2003, only about 11% of Russia’s upper class claimed to live in such new “cottages,” with the rest owning condos and luxury apartments in the inner city or older detached homes in villages and small towns. Therefore, not all the needs have been accommodated and more development is certain to take place. The environmental impact of such developments is profound. Based on preliminary LANDSAT image analysis, almost 22% of suburban “green belt” forested land within 30 km zone has been converted to new construction from 1991 to 2001. New construction is now focusing on the remaining fragments of natural vegetation, which will likely lower air quality and water quality available for the city. Ironically, the new developments advertise themselves as “clean and green” with massive investments in unnatural landscaping (seeded lawns, exotic shrubs, river and lake shore “improvements”). This investment highlights the well-known paradox of development in which people move out of town to live near nature, while destroying the wild nature they come to enjoy. “We left city for the weekend It was raining, saw no stars There were fences everywhere Our chiefs behind the bars.” Gennady Shpalikov
