Discourse,representation and urban planning: How a critical approach to discourse helps reveal the spatial re-ordering of street sex work1     

Kate Kerkin 《The Australian geographer》2004,35(2):185-192

This paper shows how a critical approach to discourse sheds light on processes of spatial re-orderings. It uses a case study of urban planning in an area of street sex work to explore the ways in which various representations of prostitution can be used to inform planning decisions. Representations of sex worker identity also expose complex spatial and social geographies and evolving processes of marginalisation and exclusion.  相似文献   

The Victorian Bushfires of 2002–03 and the Politics of Blame: a Discourse Analysis     

JOSH WHITTAKER  DAVID MERCER 《The Australian geographer》2004,35(3):259-287

This paper identifies contrasting environmental discourses on bushfire from the public debate that followed the Victorian fires of 2002–03. Submissions to the inquiry into the 2002–03 Victorian bushfires provide a particularly rich source of documentation. It is argued that environmental events such as bushfire only become political issues, or problems, when they are constituted as such through environmental discourse. Through the analysis, three contrasting discourses on bushfire are identified—here labelled the ‘conservationist’, ‘ruralist’ and ‘wise use’ discourses. In examining how different ‘constructions’ of bushfire have led to conflict, each discourse is shown to consist of a range of actors who draw on shared storylines. Having established a better understanding of the different attitudes, beliefs, interests and values that underpin debates about bushfire, the paper concludes with a brief discussion of the prospects for compromise among the discourses and the potential for improved land and fire management outcomes.  相似文献

Public Participation in Planning: an intellectual history     

Marcus B. Lane 《The Australian geographer》2005,36(3):283-299

This paper tracks the changing role of public participation in planning thought. In doing so, the paper shows that the role of public participation in planning is largely determined by the nature of the planning enterprise being undertaken. The definition of the planning problem, the kinds of knowledge used in planning practice, and the conceptualisation of the planning and decision-making context are the important determinants of the extent of participation offered to the public. The paper therefore contributes to thinking about how to evaluate public participation by showing that it can only be understood in terms of the decision-making context in which it is embedded. Specifically, it makes little sense to evaluate public participation in terms that are not shared by the planning model itself  相似文献   

Territorializing land conflict: Space,place, and contentious politics in the Brazilian Amazon     

Cynthia S. Simmons 《GeoJournal》2005,64(4):307-317

Brazil possesses a long history of violent struggle for land, and its most recent phase is occurring predominantly in the Amazon Basin. Consequently, this paper attempts to territorialize land conflict in the Brazilian Amazon, and in so doing, to illuminate the place-specific intersection of historic social, political, and economic circumstance that created a violent landscape in the so-called “South of Pará.” The paper’s premise is that such conflict can be best viewed as resulting from a dialectic between general social processes operating across spatial scales, which create necessary conditions for conflict, and place-specific historical circumstances that transform necessary into sufficient conditions. The paper presents a framework integrating the theory of contentious politics and literatures addressing violence associated with the Amazonian frontier and with resource scarcity (and abundance). The discussion and theoretical application deconstruct the environmental, cognitive, and relational mechanisms that created violence in the South of Pará, and set the stage for the Eldorado dos Carajás massacre in April of 1996.  相似文献   

A hydraulic invariance‐based methodology for the implementation of storm‐water release restrictions in urban land use master plans          下载免费PDF全文

Viviana Pappalardo  Alberto Campisano  Francesco Martinico  Carlo Modica  Luca Barbarossa 《水文研究》2017,31(23):4046-4055

A hydraulic invariance (HI)‐based methodology was developed as a tool to support implementation of storm flow control measures into land use master plans (LUMPs) for urban catchments. The methodology is based on the use of simple hydrologic analysis to compare predevelopment and postdevelopment catchment flow release scenarios. Differently from previous literature examples, for which the parcel scale is usually considered for the analysis, HI was pursued assuming the LUMP areas of transformation as the basic units for assigning storm water control measures in the form of flow release restrictions. The methodology was applied to a case study catchment in the southern part of the City of Catania (Italy), for which the LUMP re‐design has been recently proposed. Simulations were run based on the use of the EPA‐Storm Water Management Model and allowed deriving flow release restrictions in order to achieve HI at the subcatchment level for design events of different return period.  相似文献

Assessing the effectiveness of imperviousness on stormwater runoff in micro urban catchments by model simulation          下载免费PDF全文

Lei Yao  Liding Chen  Wei Wei 《水文研究》2016,30(12):1836-1848

Imperviousness, considered as a critical indicator of the hydrologic impacts of urbanization, has gained increasing attention both in the research field and in practice. However, the effectiveness of imperviousness on rainfall–runoff dynamics has not been fully determined in a fine spatiotemporal scale. In this study, 69 drainage subareas <1 ha of a typical residential catchment in Beijing were selected to evaluate the hydrologic impacts of imperviousness, under a typical storm event with a 3‐year return period. Two metrics, total impervious area (TIA) and effective impervious area (EIA), were identified to represent the impervious characteristics of the selected subareas. Three runoff variables, total runoff depth (TR), peak runoff depth (PR), and lag time (LT), were simulated by using a validated hydrologic model. Regression analyses were developed to explore the quantitative associations between imperviousness and runoff variables. Then, three scenarios were established to test the applicability of the results in considering the different infiltration conditions. Our results showed that runoff variables are significantly related to imperviousness. However, the hydrologic performances of TIA and EIA were scale dependent. Specifically, with finer spatial scale and the condition heavy rainfall, TIA rather than EIA was found to contribute more to TR and PR. EIA tended to have a greater impact on LT and showed a negative relationship. Moreover, the relative significance of TIA and EIA was maintained under the different infiltration conditions. These findings may provide potential implications for landscape and drainage design in urban areas, which help to mitigate the runoff risk. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献   

Historical paths to current unrest: Extending the temporal lens in analysing geographies of agrarian change and conflict     

《Geoforum》2016

The proliferation of soybean monoculture and its expansion into previously marginal territories in Argentina have resulted in land conflicts and attacks on peasant communities that possess land without having secured tenure. However, the rapid and intensive modernisation and industrialisation of agriculture production has had differentiated effect on different territories in Argentina. This article posit that understanding these differences requires an extended temporal analysis. While social research tends to focus on the present or recent past, this paper joins calls for greater attention to historical context and processes when examining current social dynamics and geographies. Focusing on the province of Santiago del Estero in Northwest Argentina, this paper provides a particular temporal-thematic approach for conducting such a historical path analysis, which here focuses on the province’s changing agrarian structures and political shifts that resulted in a complex, irregular and subsequently unstable land tenure system.  相似文献
