Planning a Prosperous Sydney: The challenges of planning urban development in the new urban context

Since their post-war inception, Sydney's metropolitan plans have tended to be overtaken by the social, economic and environmental conditions they have had to confront. The depth and scope of Sydney's recent urban transformation threatens again to overtake metropolitan planning capacity creating, in the context of competitive globalisation, a potentially significant market disadvantage for the city, not to mention poor urban development outcomes. This paper reviews Sydney's post-war metropolitan planning strategies, examining the social and economic contexts and the policy paradigms in which they have been framed, in order to draw out the lessons to be learned from their successes and failures. We argue that future success in planning urban development will rely on richly informed and fine-grained understanding of the complex spatial outcomes of Sydney's ever-deeper global integration. Only such fine-grained understanding can empower metropolitan planning to be responsive to the evolving challenges of managing development in the contemporary urban context.     

Employment and Socio-spatial Relations in Australia's Cultural Economy

This paper examines the significance and contribution of Australian 'creative' industry activities in light of recent debates on the emergence of the 'cultural economy of cities'. First, census employment data and business location counts are used to illustrate patterns of metropolitan primacy and concentration in the cultural industries both across states and in Sydney. Second, the specificities of the locations of cultural production, and the links between cultural industry activities and wider urban-regional change are explored in more detail. A set of observations of urban-regional change is used to demonstrate how the notion of 'cultural economy' should include complex interactions between the material activities of consumers and producers, and the discursive worlds of image makers and place marketers. Urban renewal, housing market pressures and intra-regional migration all mediate Australian experiences of the 'cultural economy'. Such interactions, in addition to key quantitative data on employment and business activity, suggest important policy considerations.     

Reflections on a White Discipline

Utilizing a partially autobiographical format, this article considers the practice and study of race within geography. I argue that the overwhelmingly white composition of the discipline has very real implications for both individual experiences and our intellectual production and disciplinary culture. I explore these issues by drawing on my own experiences as a Chicana within geography, and by examining the extent to which one area of research, environmental justice, has engaged questions of race and the consequences of that engagement. I conclude with some general remarks on what it might take to significantly diversify geography.     

SARS的世界性和中国旅游商品的可持续开发

SARS是一种世界性灾难题，医学专家提示，它将与人类长期共存。但2003年春天的SARS却对华人经济圈造成巨大冲击。在这种疫情的紧急状态和长期影响下，中国国民经济各行业中，旅游业所受冲击很大。人民的生命安全重于经济利益，但如何最大限度缩小损失是我们旅游研究者的责任。基于这种背景，结合我国旅游商品长期存在的问题，本文重点探讨了在SARS的紧急状态下，中国旅游商品如何实施可持续开发。作者认为，中国旅游商品开发应坚持走由被动型向主动型转变、计划型向市场型转变、模糊型向标准型转变、短期型向长期型转变的可持续发展之路。     

国外开发欠发达地区的经验教训对中国西部城镇化的启示

美国、英国、日本、意大利、巴西等国先后对本国欠发达地区进行了开发建设。它们以城镇化为动力、大力发展城镇工业，已经取得许多成功经验，也有着深刻的教训。中国西部大开发可从国外开发欠发达地区的经验教训中受到启迪，以城镇化为增长点带动区域经济的全面发展，重视生态环境的保护和建设，加强以交通运输为重点的城镇基础设施建设，探索出西部地区城镇工业独特的发展道路，实现经济、社会和环境的可持续发展。     

Engineering geology of loess and loess-like deposits: a commentary on the Russian literature

Loess and loess-like deposits were much studied in the Soviet Union, and are currently under investigation in Russia and surrounding countries. There is a vast literature in Russian, which touches on all aspects of loess science and technology. In particular, the studies of the origin of collapsibility are almost totally in Russian, and of course studies on the various regions of Russia and the countries of the Former Soviet Union FSU appear in Russian. This review looks at the literature in Russian and attempts to pick out key contributors, major topics and works and to identify the critical regions and zones of investigation. Because so many regions of the FSU had people living on loess ground, there is a vast literature on engineering geology and ground engineering topics, and this tends to dominate all the literature on loess in Russian. Following Russian practice, the fine-grained deposits under consideration are divided into loess and loess-like deposits. Three main topics are recognised across the whole spectrum of loess research: formation and distribution of loess deposits; stratigraphy, cyclicity and palaeoclimatology; and engineering topics, in particular hydrocollapse and subsidence, and we concentrate on the engineering geology topics. An attempt is made, based on the map of Abelev and Abelev [Abelev, Yu.M., Abelev, M.Yu., 1968. Fundamentals of design and construction on collapsible macroporous soils, 2nd ed. Stroiizdat, Moscow, 431 pp. (in Russian)] of collapsing loess deposits, to define seven loess regions within the geographical limits of the old USSR. The seven regions are those where geotechnical problems might be expected.     

‘Bringing government to the people’: women, local governance and community participation in South Africa

This paper considers the ongoing political transformations in South Africa in the context of debates about good governance and participatory democracy. It first appraises the current transformations of local government in South Africa, focusing specifically on relationships between gender equality and citizenship on the one hand, and local government policy, legislation, and community participation on the other, and then explores meanings of participation and how they inform approaches towards local socio-economic development. The findings of primary research conducted with civil society organisations and black women in communities in the Cape Town metropolitan area are explored through three interrelated themes. First, the model of structured participation that is central to South Africa’s democratic transformation is assessed from the perspective of black women. Second, cultures of alienation, both within local governance structures and amongst black women and the extent to which recent restructuring is combating or contributing to these are explored. Third, how participation policies are dealing with conflict within and between target groups are analysed, whether stakeholder group politics obliterate important differences in interests and whether alternative structures might be more effective in terms of women’s participation and empowerment. Finally, the findings are interpreted in relation to theoretical concepts of good governance and participatory democracy, and the potential and problems of realising South Africa’s transformation process toward developmental local government are assessed.     

中国西部退耕还林(草)和沙漠化土地绿化的区域性气候效应

中国正在实施的西部大开发必将导致较大规模的土地利用和地表覆盖(LULC)变化,其中最重要的两类LULC变化是退耕还林(草)和沙漠化土地绿化工程。利用最新的全球地表特征资料数据库(GLCCD)识别以上两项生态建设工程的实施规模与范围,并以此更新了目前比较流行的区域气候模式的下边界条件,利用修正了的区域气候模式研究上述大规模LULC变化可能对中国区域性气候造成的影响。使用的卫星资源数据库是由美国地质测绘局(USGS)和Nebraska-Lincoln大学牵头,根据NOAA卫星的AVHRR资料、USGS掌握的高分辨率数字化地图,以及生态区划和植被分布等资料组建的。     

Replacing carbon lost from forests: an assessment of insurance, reserves, and expiring credits

Concern over the “non-permanence” or reversibility of carbon sequestration projects has been prominent in discussions over how to develop guidelines for forest project investments under the Clean Development Mechanism (CDM) of the UNFCCC Kyoto Protocol. Accordingly, a number of approaches have been proposed that aim to help ensure that parties do not receive credit for carbon that is lost before project obligations are fulfilled. These approaches include forest carbon insurance, land reserves, and issuance of expiring credits. The potential costs of each of these different approaches are evaluated using a range of assumptions about project length, risk and discount rate, and a comparison of costs is ventured based on the estimated reduction in value of these credits compared with uninsured, and permanent credits. Obstacles to participation in the different approaches are discussed related to problems of long-term commitments, project scale, rising replacement costs, and low credit value. It is concluded that a system of expiring credits, which could be coupled with insurance or reserves, could guarantee obligations that span time-scales longer than that of conventional insurance policies while maintaining incentives for long-term sequestration.
