Análisis del desarrollo y evolución del objetivo e implementación de las operaciones estrátegicas planteadas en los planes de ordenamiento territorial de Bogotá desde el 2000 al 2013: caso de estudio operación estratégica centro

La planificación urbana en la consolidación de las ciudades ha venido adquiriendo una gran importancia para el desarrollo urbano, a través de instrumentos de gestión urbana. Dentro de esta investigación se analiza las operaciones estratégicas como un instrumento de gestión que ha tenido cambios en su objetivo, alcance e implementación para poder transformar y mejorar a través de intervenciones urbanas los temas físicos, económicos, sociales y culturales dentro de los territorios. A partir de lo anterior, se identificaron cinco elementos que han limitado la implementación de las operaciones estratégicas que son, una visión a largo plazo, la falta de una gerencia especifica, voluntad política, continuidad y la coordinación y comunicación interinstitucional.

Managing land-use conflict around urban centres: Australian poultry farmer attitudes towards relocation

In analysing the release of agricultural land to urban development, the urban fringe literature has not focused on whether farmers are able to relocate from the urban fringe to remoter rural areas. Through interviews with representatives from the poultry industry in two Australian states, this paper identifies that poultry farm relocation strategies are constrained by off-farm economic relations, the land-use planning system and financial considerations. Closely aligned to these constraints on relocation is the on-going process of poultry farm intensification, which is seen as presenting rising problems for land-use management around expanding metropolitan centres in Australia. Of particular concern is the potential for amenity complaints and associated land-use conflicts, which have not been comprehensively investigated. Recognising that existing environmental and land-use planning controls are ineffective in producing amicable solutions when conflict involving poultry farming is at its most intense, the paper calls for improvements to the regulatory system, including greater consideration for how the process of relocation can be encouraged.

Urban mammals: what does the future hold? An analysis of the factors affecting patterns of use of residential gardens in Great Britain

1Urban areas are predicted to grow significantly in the foreseeable future because of increasing human population growth. Predicting the impact of urban development and expansion on mammal populations is of considerable interest due to possible effects on biodiversity and human-wildlife conflict. 2The British government has recently announced a substantial housing programme to meet the demands of its growing population and changing socio-economic profile. This is likely to result in the construction of high-density, low-cost housing with small residential gardens. To assess the potential effects of this programme, we analysed the factors affecting the current pattern of use of residential gardens by a range of mammal species using a questionnaire distributed in wildlife and gardening magazines and via The Mammal Society. 3Twenty-two species/species groups were recorded. However, the pattern of garden use by individual species was limited, with only six species/species groups (bats, red fox Vulpes vulpes, grey squirrel Sciurus carolinensis, hedgehog Erinaceus europaeus, mice, voles) recorded as frequent visitors to > 20% of gardens in the survey. 4There was a high degree of association between the variables recorded in the study, such that it was difficult to quantify the effects of individual variables. However, all species/species groups appeared to be negatively affected by the increased fragmentation and reduced proximity of natural and semi-natural habitats, decreasing garden size and garden structure, but to differing degrees. Patterns of garden use were most clearly affected by house location (city, town, village, rural), with garden use declining with increasing urbanization for the majority of species/species groups, except red foxes and grey squirrels. Increasing urbanization is likely to be related to a wide range of interrelated factors, any or all of which may affect a range of mammal species. 5Overall, the probable effects of the planned housing development programme in Britain are not likely to be beneficial to mammal populations, although the pattern of use examined in this study may represent patterns of habitat selection by species rather than differences in distribution or abundance. Consequently, additional data are required on the factors affecting the density of species within urban environments.

Resilience planning, economic change and the politics of post-recession development in London and Hong Kong

For much of the 1990s and 2000s, the emphasis of urban policy in many global cities was on managing and mitigating the social and environmental effects of rapid economic growth. The credit crunch of 2008 and the subsequent recession have undermined some of the core assumptions on which such policies were based. It is in this context that the concept of resilience planning has taken on a new significance. Drawing on contemporary research in London and Hong Kong, the paper shows how resilience and recovery planning has become a key area of political debate. It examines what is meant by conservative and radical interpretations of resilience and how conservative views have come to dominate ‘recovery’ thinking, with élite groups unwilling to accept the limits to the neo-liberal orthodoxies that helped to precipitate the economic crisis. The paper explores the implications of such thinking for the politics of urban development.

A review of urban roughness sublayer turbulence

It is becoming increasingly important that we can understand and model flow processes in urban areas. Applications such as weather forecasting, air quality and sustainable urban development rely on accurate modelling of the interface between an urban surface and the atmosphere above. This review gives an overview of current understanding of turbulence generated by an urban surface up to a few building heights, the layer called the roughness sublayer (RSL). High quality datasets are also identified which can be used in the development of suitable parameterisations of the urban RSL. Datasets derived from physical and numerical modelling, and full-scale observations in urban areas now exist across a range of urban-type morphologies (e.g. street canyons, cubes, idealised and realistic building layouts). Results show that the urban RSL depth falls within 2 – 5 times mean building height and is not easily related to morphology. Systematic perturbations away from uniform layouts (e.g. varying building heights) have a significant impact on RSL structure and depth. Considerable fetch is required to develop an overlying inertial sublayer, where turbulence is more homogeneous, and some authors have suggested that the “patchiness” of urban areas may prevent inertial sublayers from developing at all. Turbulence statistics suggest similarities between vegetation and urban canopies but key differences are emerging. There is no consensus as to suitable scaling variables, e.g. friction velocity above canopy vs. square root of maximum Reynolds stress, mean vs. maximum building height. The review includes a summary of existing modelling practices and highlights research priorities.

Modelos de gerenciamento para o desenvolvimento planejado das cidades: o caso da cidade de Vitória

A dissertação trata de modelos de gerenciamento para o desenvolvimento planejado das cidades. Seu objetivo é a identificação e a análise dos modelos institucionais usados no processo de planejamento e gerenciamento urbano da cidade de Vitória, a partir da década de 70. Seu desenvolvimento mostra um levantamento histórico do planejamento e gerenciamento urbano da cidade; descreve algumas iniciativas de planejamento e planos de desenvolvimento urbano elaborados para a cidade e analisa tais iniciativas e planos sob os aspectos dos objetivos alcançado, da hierarquização desses objetivos, do custo de se atingir cada objetivo, da construção institucional, dos marcos de avaliação e dos resultados alcançados. A pesquisa foi histórico-descritiva e explicativa, realizada por meio de pesquisa de campo, bibliográfica, documental e telematizada. Seus resultados conduziram à conclusão de que não há tecnologia gerencial disponível para administrar macro-aglomerados urbanos e que o processo de planejamento é um modelo dinâmico destinado a controlar eventos aleatórios não podendo ser pulverizado entre várias jurisdições e nem centralizado num único agente ou entidade.

Política habitacional em zonas urbanas: o caso do conjunto habitacional Vila da Barca, em Belém

o presente estudo é o resultado da pesquisa feita durante o Mestrado em Gestão Empresarial da Escola de Administração Pública e de Empresas, da Fundação Getúlio Vargas. Este trabalho buscou compreender a produção espacial da cidade de Belém, precisamente sobre a Vila da Barca, situada às margens da Baia do Guajará, região que teve alguns de seus moradores remanejados para o Projeto de Habitação e Urbanização do local como parte da política pública habitacional da área, realizada pelo Governo Municipal em parceria com o Governo Federal. Este projeto habitacional é gerenciado pela Secretaria Municipal de Habitação - SEHAB. O objetivo principal deste estudo voltou-se para a avaliação do Projeto de Habitação da Vila da Barca no sentido de identificar como se efetivou o processo de concepção, remanejamento e reinstalação das famílias do setor analisado. Além disso, buscou-se conhecer o que foi feito em relação ao desenvolvimento desse espaço urbano. A metodologia se desenvolveu em duas fases: aplicação de questionários aos moradores e, de entrevistas aos técnicos envolvidos (Gerente de Desenvolvimento Urbano (GIDUR); Técnico Social e Engenheiro, funcionários da Caixa Econômica Federal em Belém). A pesquisa procurou demonstrar a opinião dos envolvidos no processo de efetivação dessa política pública, compreender a produção desse espaço urbano em suas diferentes dimensões e perceber os aspectos positivos e negativos do projeto, verificando alguns elementos de construção desse espaço. Como conclusão, percebe-se que é preciso construir formas atuais eficazes de exercer por parte da sociedade o controle social sobre o poder do Estado e sobre os mecanismos que controlam o mercado. Esse é o desafio maior da contemporaneidade

Urban transport planning in a context of demographic, social, economic and technological change

Transport planning necessarily takes into account more than just the immediate time-frame. In the case of urban transport, planning needs to come up with solutions in regard to infrastructure which is expensive and may have a useful life extending over several decades. Therefore, planning must take note of economic, technological, social and demographic changes that influence trips undertaken.The purpose of this article is to explore some of the trends that may well be observed in upcoming decades. The article arrives at the conclusion that, in a period of considerable change and uncertainty, failure to take heed of recent trends may result in the construction of infrastructure that is not always the most appropriate and, what is more, that urban development militates against the efficient operation of public transport and, as a result, is likely to jeopardize the sustainability of cities in the long term.
