改革开放以后北京城镇居民食品消费生活的变化

改革开放以后的20年,北京城镇居民的食品消费生活经历了从勉强温饱到温饱再到小康状态的转变。在前一阶段,居民主要是追求吃的数量的扩充,主要特点是实现了从以“主食”消费为主向以“副食”消费为主的转化;在后一阶段,居民开始追求吃的质量的提高,营养、新鲜、方便、快捷的食品受到普遍欢迎。北京城镇居民食品消费生活的这种变化在某种程度上是中国居民生活水平普遍提高的反映,而中国绝大多数人的生活能够不断地得到改善,这一看似简单的现象正是中国渐进的社会主义改革不断取得成功的社会基础。     

Prospects for the Rural‐Urban Fringe in Australia: Observations from a Brief History of the Landscapes around Sydney and Adelaide

Despite being a major site of recent population growth and, arguably, a key arena for sustainability concerns, the rural‐urban fringe has received relatively little attention in the literature concerning Australian cities and urban policy. To address this shortcoming the authors review post‐World War II efforts to plan the rural‐urban fringes of Sydney and Adelaide and find a number of issues for contemporary policy‐makers. First, the fringe is becoming increasingly complex due to multi‐faceted demographic change, a broadening economic base and demands for better environmental management, all within the context of an evolving understanding of sustainability. Second, water resource management, partly under the auspices of integrated natural resource management, is assuming a much higher priority than in early fringe planning endeavours, which emphasised urban containment, agricultural land protection and landscape conservation. Third, and partly as a consequence of this shift of priorities, there is also evidence of changes to the nature and focus of policy tools used in the fringe, with land management concerns now cutting across traditional land use planning. Finally, and fundamentally, these observations raise questions about how future governance of the fringe should be organised. Together these four themes pose an enthralling series of challenges for policy‐makers for which much more research and discussion are needed.     

Consumption,Environmental Sustainability and Human Geography in Australia: a Missing Research Agenda?

‘Consumption’ is a central concept in the global environmental sustainability agenda. However, one important argument from Agenda 21 — that all social actors must now practise ‘sustainable consumption’— has been publicly and politically marginalised in high‐income countries such as Australia. Geographers potentially have a role in bringing consumption back onto the agenda by constructing a critical geography of consumption. Such research can help understand how the contextual use of natural resources is perceived and practised, and how consumption helps to shape contemporary social relations. This body of knowledge is vital for building sustainable development into everyday lives. Yet a focus on urban consumption perceptions and practices appears somewhat lacking in Australian geography. Ways forward can be drawn from international geography, such as in the United Kingdom where a substantial body of work has drawn a complex picture of contemporary consumption and environmental understanding. It has also challenged prevailing ‘ecological modernisation’ policy approaches, which ignore consumption's cultural facets. In sum, considering consumption in Australia can offer insights into cultural practices expressed through consumption; can challenge and add to European geographical literatures, and can also contribute to sustainability debates by offering alternatives to currently ineffective policy discourses.     

From sustainable development to carbon control: eco-state restructuring and the politics of urban and regional development

The management of carbon emissions holds some prospect for challenging sustainable development as the organising principle of socio-environmental regulation. This paper explores the rise of a distinctive low-carbon polity as an ideological state project, and examines its potential ramifications for the regulation of economy–environment relations at the urban and regional scale. Carbon control would seem to introduce a new set of values into state regulation and this might open up possibilities for challenging mainstream modes of urban and regional development in a manner not possible under sustainable development. But low-carbon restructuring also portends intensified uneven development, new forms of state control and a socially uneven reworking of state–society relations. In order to explore these issues we start by setting out a framework for conceptualising environmental regulation based around the idea of eco-state restructuring. This idea is introduced to capture the conflicts, power struggles and strategic selectivities involved as governments seek to reconcile environmental protection with multiple other pressures and demands. Overall the paper seeks to make a distinctive contribution to theoretical work on state environmental regulation and the emerging spatial dimensions of climate policy.     

Regulating Regional Uneven Development and the Politics of Reconfiguring Belgian State Space

Abstract: This article mobilises a strategic‐relational approach to state spatial restructuring to overcome the weaknesses of the conventional “New Regionalist” account in economic geography of the resurgence of the region as a strategic site for economic governance. Focusing on hegemonic projects and the shifting nexus of spatial dependencies and engagements through which these are reproduced, undermined and transformed, the role and geography of political agency in state spatial restructuring is highlighted. To illustrate this point, I analyse the construction of new regional state spaces in Belgium, paying particular attention to the hegemonic projects that create a social basis for particular state spaces, the construction of collective agency on different scales (Belgian‐national and Flemish‐regional) and the various ways in which these processes are informed by pre‐existing state spatial and scalar selectivities.

Exploring the land development process and its impact on urban form in Hamilton, Ontario

The form of many Canadian cities has dramatically evolved over the past six decades due to urban sprawl. Several patterns can characterize this evolution including unlimited horizontal expansion of the city, leapfrog, and low‐density residential development at the outskirts, and widespread strip commercial and power centre retail development. Hamilton, Ontario is an example of a Canadian city that has experienced suburbanization and sprawled development for several decades. However, the nature of this sprawled development is unclear and its impact on urban form is not entirely understood. In this article, several hypotheses pertaining to sprawled land development and urban form are postulated and tested. The tests rely on point source data of the developed land parcels in Hamilton during the period 1950–2003. A number of spatial statistics techniques, including kernel estimation and complete spatial randomness (CSR) K‐function tests, are employed to examine the emerging nature of urban form. We hypothesize that while the city has been sprawling, the ongoing land development process is leading urban form into multinucleation. To support this assumption, we further hypothesize the existence of an interdependent spatial relationship between residential and commercial land uses at the emerging nuclei. Accordingly, we examine the strength of co‐clustering among these land use activities over time. The findings indicate that while the city has been sprawling, several consequent urban nuclei with mixed land use activities have been emerging and become more visible in recent years. This is an indication that the city's form is progressively becoming multinuclear. Furthermore, the estimates for the 1990s indicate interdependence between the locational patterns of residential and commercial land development. Co‐clustering between these two types of land uses is bi‐directional and occurs at a time lag of three to seven years. These findings affirm the existence of interdependence between land use activities at the observed nuclei, which support the emergence of a multinucleation.
