Loblolly pines in Texas and Louisiana exhibit different reactions to moisture extremes, as indicated by the susceptibility of weakened individuals to attack by southern pine beetles. In Texas, intense insect outbreaks among pines occur during periods of extreme moisture surplus, whereas extreme moisture deficits render the Louisiana pines susceptible to attack. Intraspecies tree reponse to moisture extremes therefore appears to be spatially variable and partially dependent upon the frequency occurrence of severe climatic conditions.  相似文献

Abstract

This article offers video lessons that interweave visual and written materials in order to introduce university undergraduates (who may or may not be geography majors) to some recent shifts in geographic inquiry. What is often described as the “cultural turn” in human geography invites us to examine more closely the politics of representation, whereby power relations animate the ever-unfolding construction of cultural identities. These examples of pedagogy explore the formulation of geographic knowledge about two cultural groups—the Maori and the Romany (a.k.a. Gypsies).  相似文献

ABSTRACT

Set against the wider background of global suburbanization, this paper contributes to the emerging literature on the formation of technoburbia in China, and more importantly, the potential “urban contradictions” accompanying this process. Through a bottom-up empirical exploration of the Future Sci-tech City Corridor in Hangzhou and its embedded Featured Town initiative in particular, we observe how the future of technoburbia in China is by no means free from similar challenges in housing affordability and labor stratification. However, these contradictions are managed entirely differently in China. Nevertheless, the highly planned nature of China’s technoburbia also rubs up against political decentralization, demographic change and economic upgrading, implying significant trials and tribulations along the way.  相似文献

Earlier research shows that between 1971 and 1981, the number of farmers in New Zealand increased and their average age decreased, whereas between 1981 and 1991, the opposite trend occurred. This article addresses the issue of change in the average age of farmers since 1991 using recent census data. It reviews the difficulties in obtaining good data and describes the adjustments need to be made to obtain a consistent data series from 1971 to 2006. The long-term trend for increasing age of farmers and farm workers continues. This demographic aspect of farm structural change is then discussed in terms of the sustainability of farming by reference to productivity and potential problems with succession.  相似文献

This article argues that urban skateboarding and the laws by which the city is governed must be understood as intertwined. The transformation of skateboarding's most popular practices from the 1970s onward are a product of an ongoing dialectical engagement between young people and the law. When faced with shifting landscapes of property and liability, young skaters have adapted their practices, seeking out new types of terrain. This search has led skateboarding into the public spaces of the city and regimes of urban governance. Contemporary efforts to build public skateparks in cities such as Seattle, Washington are properly contextualized as part of a continuing evolution of skaters' agency in responding to and capitalizing on openings in the legal landscape. By working both within the political system and constructing skateparks outside conventional political avenues, skatepark advocates seek spaces that are free from increasingly restrictive conventional logics of private and public property.  相似文献

This article contributes to the ongoing scrutiny of the travels of critiques of neoliberalism in urban studies. Using the case of a state-led urban regeneration program implemented in Portugal since 2000, the Polis Program, the article weighs in on meta-analytical discussions about the hegemonic status of neoliberalism as a theoretical concept and as an analytical framework and on discussions about the travels of dominant critiques of neoliberalism beyond the sites of epistemological production. The article argues that the current analytical overinvestment in neoliberalism may obscure important drivers of contemporary urbanization and that recourse to a diversity of concepts may be a more profitable line of inquiry. The article suggests that current efforts at epistemological renewal within urban studies benefit from taking up cities in the “borderlands” of urban theory as relevant cases in their own right. The article offers further considerations on the purchase of neoliberalism in contemporary urban literature.[Key words: neoliberalism, critiques, urban theory, urban planning and policy, Portugal, Polis Program]  相似文献

Power relationships structure discourse and its influence on policy and rural land use planning, but little research has examined how this might be observed in the dynamics of rural landscape transition. In a qualitative case study of the Ovens catchment, Victoria, Australia, discursive power is observed through sites of tension between informant interpretations of past, present, and future landscapes and contemporary local decision making. Three main tensions and an observation emerged that suggest discourse and power can be observed through the transfer and support of social memory narratives. We conclude that the identification of tensions between stakeholder perceptions of the past, present, and future of their landscape; awareness of the influence of those interpretations on current decision making; and attention to social memory narratives can provide invaluable insights for those seeking to understand local relationships of power.  相似文献

This article examines land-use development applications for minority religious facilities in two local government areas on the rural–urban fringe of metropolitan Sydney, Australia. Using critical discourse analysis and underpinned by Lefebvre's (1991) conceptual triad of space, the work interrogates the way in which place identity is generated and codified both by land-use planners and local residents through spatial representation. This representation is revealed in discourses around the compatibility of minority religious facilities for particular zones, lack of a sufficient minority population and social disruption. These discourses reveal a construction of peri-urban space that is aligned with particular elite Anglo-Australian activities (horse riding and gentleman farms) and land uses (rural residential, small-scale agriculture and the ‘bush-church’). These case studies illustrate the potential for the creation of exclusionary, abstract space by urban planners but also the ways in which local residents use discoursive strategies to ensure the stability of their position as elites in rapidly changing spatial situations.  相似文献

Developed here is an integrated framework for identifying production–living–ecological space(PLES) quantitatively at grid scale from the perspective of multifunction land use, and 25 compound space types are classified to highlight the multiple functions of PLES. As a typical mountainous city in northern Hebei province, Zhangjiakou is used as a case study, and the results show that more than 80% of the land space in Zhangjiakou has remarkable triple functionality. The living-dominated space and ...  相似文献

"The article analyses the population growth in rural counties of the U.S.A. for 1970-80 and 1980-86. The growth rates are examined on different levels of aggregation (individual counties, subregions and regions) and in relation to several possible determinants of growth. The main objective of the study is to examine whether the growth patterns in the eighties support the hypothesis of a turnaround in the population development of rural areas.... The results reveal a diversity of growth patterns and significant regional differences. Rural counties within the daily urban system of a metropolitan area have significantly higher growth rates than peripheral rural counties. The results do not support the notion of a turnaround of long established trends. The trends in the eighties bear more resemblance to traditional growth patterns of rural areas."

ABSTRACT

This article examines the stomachs of ruminant livestock as a site of biotechnological intervention and analyzes efforts to reengineer ruminant digestion as a case of the real subsumption of nature. The livestock industry’s capacity to increase production is constrained by available grazing land and concern about environmental consequences of ever-increasing livestock numbers. Ruminants are also a significant source of greenhouse gases and the mitigation of methane is a recognized priority within the global climate framework. The pursuit of “sustainable intensification” and new technological fixes have been identified as preferred responses to these constraints. The case of ruminant methane calls into question assumptions about the primacy of accumulation, rather than regulation, in driving the real subsumption of nature. The pursuit of technological fixes within biologically based industries may be motivated by a need to stabilize the conditions of production, and regulation itself can provide an impetus for the real subsumption of nature.  相似文献

Human activities in the marginal zone of the Changtang Plateau(CTP) uninhabited area are important research topics in China and globally. Based on the core-periphery theory of geography, this paper selected three counties in the marginal zone of the CTP uninhabited area with significant transitional physical geography features and socio-economic conditions as case areas. We used the data set of settlement patches identified by visual interpretation in Google Earth Pro, combining them with field ...  相似文献

An analysis is made of the oil pollution of the Ob river waters using a long-term (1993–2013) hydrochemical monitoring of oil fields in Khanty-Mansi Autonomous Okrug. Contents of oil hydrocarbons (OHC) were determined in 4277 samples from the main Ob channel, and in 7076 samples from its anabranches by using infrared spectrometry. An increase in MAC (0.05 mg/dm3) was observed in 28% of the samples from the main channel, and in 32% from the anabranches. The total percentage of samples with an extremely high (> 50 MAC) and high (30–50 MAC) pollution level made up 0.3% of the samples for the anabranches, and 0.1% for the main channel. Maximum pollution was revealed in the eastern part of Okrug, from its eastern boundary to the mouth of the Trom’egan river which is associated with a considerable number of accidents on the pipelines within the Nizhnevartovskii district. The upper and lower quantiles in the most polluted anabranches, Pasl and Bagras, are 0.03–01.7 and 0.032–0.16 mg/dm3, respectively, whereas in the main Ob channel they vary from 0.022 to 0.065 mg/dm3 (0.4–1.2 MAC). The methods of geoinformatics and mathematical statistics were used to assess a dependence of OHC on the number of pollution sources (well clusters, and the area of oil spills) in zones at different distances from the river channels. By calculating the Spearman correlation coefficients, it was shown that OHC contents are dependent mainly on the number of wells, and on the area of oil spills located at less than 2 km from the channels.  相似文献

Groundwater exploitation is an essential aspect of the numerous processes of transforming the urban natural environment for human gains. We use the political ecology of borehole exploitation in Nigeria’s urban environment to understand the micro-and macro-level processes mediating the transformation and changes in urban “groundwater scape”. The fieldwork processes depend on field counting of borehole distribution, in-depth and semi-structured interviews, and a review of secondary literatures. We argue that the social and environmental changes arising from the exploitation of groundwater bespeak the active and continual manifestation of the interplay of combustible interests and power friction among institutional agents within the permissible range of the natural environment. Such dynamic power relations engender a pattern of socio-natural transformation consistent with Swyngedouw’s notion of urban metabolism- “a series of interconnected heterogeneous and dynamic but contested and contestable processes of continuous quantitative and qualitative transformations that re-arranges humans and non-humans in new and often unexpected ways”.  相似文献
