Le chez-soi et la construction des identités géographiques individuelles : habiter en communauté fermée à São Paulo (Brésil)

Ce mémoire propose d’aborder la relation entre le chez-soi et la construction des identités géographiques. Plus précisément, il s’agit de se pencher sur l’importance que revêt cette dimension intime et familière de l’habitat dans la part des identités qui mobilise les lieux, territoires et paysages comme référents. S’interroger à cet égard s’avère d’autant plus pertinent aujourd’hui, dans un contexte de fragmentation socio-spatiale à l’échelle urbaine et de prolifération d’enclaves résidentielles qui témoignent d’un enfermement et d’une introversion de l’habitat. Nous abordons la question à travers le cas du projet AlphaVille São Paulo (Brésil), un large développement résidentiel composé de plusieurs communautés fermées. Les entretiens semi-directifs réalisés auprès de onze habitants de ce projet permettent de confirmer l’importance du chez-soi dans leur construction identitaire. En effet, le chez-soi en communauté fermée représente l’aboutissement d’un parcours géographique et permet au regard des habitants rencontrés une expérience de l’espace résidentiel qui s’approche de celle qu’ils ont connue au cours de l’enfance et qu’ils ont perdue à mesure que la ville s’est transformée en un milieu de plus en plus hostile. Ainsi, il leur permet dans une certaine mesure de revivre un idéal perdu. Néanmoins, habiter en communauté fermée contraint les territorialités : au sein de la métropole, le chez-soi fait figure de refuge. Il n’en demeure pas moins que les réponses des résidents révèlent une conscience que leur choix d’habitat constitue en quelque sorte une fuite de la réalité. Ainsi, ils entretiennent à l’égard de leur milieu de vie une relation qui oscille entre illusion et désillusion.

La ocupación de áreas de manantiales en la región metropolitana de São Paulo: los mercados de tierras en las zonas rurales periurbanas

Las ocupaciones ilegales, vinculadas a los procesos especulativos del mercado de tierras, generan numerosas tensiones ambientales y sociales. Estos conflictos se ven reforzados por la debilidad de las instituciones y los choques de intereses entre los agentes económicos. La mayoría de los estudios sobre los procesos de ocupación de las zonas rurales periurbanas en el Estado de Sao Paulo,  Brasil, se basan en la suposición de que de la Ley de Protección de los Manantiales (LPM) se genera la caída de los precios de las tierras. En este contexto, el presente estudio aporta un análisis  de la urbanización de estas áreas en los manantiales de la región metropolitana de Sao Paulo, del control de la influencia de la LPM en las ocupaciones y de la depreciación/valorización de terrenos  ubicados en esa zona. Los resultados muestran que el comportamiento de los precios de las tierras agrícolas de los municipios pertenecientes a las cuencas hidrográficas de la zona no estuvo influenciado  por la LPM. La influencia predo  inante, en este caso, es la de las políticas macroeconómicas del plan real de Brasil.

Programas museológicos e museologia aplicada : o centro de memória do samba de São Paulo como estudo de caso

Foi com muita satisfação que recebemos o convite para a publicação nos Cadernos de Sociomuseologia, tanto pelo fato de considerá-lo uma importante publicação na área da Museologia em língua portuguesa como, também, pela razão de termo-nos amparado, inúmeras vezes, nas reflexões de profissionais de Portugal no que diz respeito à temática abordada, ou seja, a programação museológica. Embora este trabalho tenha sido inicialmente apresentado como monografia de conclusão das actividades académicas no âmbito do Curso de Especialização em Museologia do Museu de Arqueologia e Etnologia da Universidade de São Paulo, realizadas entre os anos de 2001 e 2002, sofreu mínimas alterações. A escolha pelo tema deu-se em virtude das inquietações e reflexões profissionais e discentes no sentido de buscar a experimentação de metodologias passíveis de contribuição às necessidades no campo da Museologia dentro da realidade brasileira. Tem, como estudo de caso, um trabalho de consultoria realizado para a Divisão de Iconografia e Museus do Departamento do Património Histórico da Secretaria Municipal de Cultura de São Paulo e da Anhembi Turismo e Eventos da Cidade de São Paulo, que consistia em diagnosticar o acervo pertencente à Anhembi visando à implantação do Centro de Memória do Samba de São Paulo.

Museum of the City of São Paulo: A new paradigm of City Museums in the Era of Megalopolises

The City is a tomography of the present, indicating to the future, strata of past times. Nowadays city growth averages one million people every week; while back in 1950 there were eighty six cities with more than one million inhabitants, today they are four hundred all over the world. However the most significant effect of the urban process is, doubtless, the explosion of megacities. It took one century for the urban population – around three point four billion inhabitants – to surpass the number of people in the country, but United Nations projections indicate that by 2025, urban population will reach 61% of the total. Creating a new city museum in São Paulo requires that, in a first analysis, one should consider as geographic area of study some fifteen hundred square kilometres corresponding to the patrimonial intervention area. That is the area of the Municipality, politically divided into ninety six districts where eleven million people live, while approximately twenty million people live in the metropolitan area

Ensuring the right to the city: pro-poor housing, urban development and tenure legalization in São Paulo, Brazil

São Paulo is one of Latin America’s most modern and developed cities, yet around one-third of its 10 million inhabitants live in poor-quality housing in sub-standard settlements. This paper describes the response of the São Paulo municipal government that took office in 2001. Through its Secretariat of Housing and Urban Development, it designed a new policy framework with a strong emphasis on improving the quantity and quality of housing for low-income groups. Supported by new legislation, financial instruments and partnerships with the private sector, the mainstays of the new policy are integrated housing and urban development, modernization of the administrative system, and public participation in all decision-making and implementation processes. The programmes centre on upgrading and legalizing land tenure in informal settlements, and regeneration of the city centre. The new focus on valuing the investments that low-income groups have already made in their housing and settlements has proved to be more cost-effective than previous interventions, leading to improvements on an impressive scale.

Evaluation of thermal simulation of households in the metropolitan region of So Paulo, Brazil

This paper aims at assessing the performance of a program of thermal simulation (Arquitrop) in different households in the city of Sao Paulo, Brazil. The households were selected for the Wheezing Project which followed up children under 2 years old to monitor the occurrence of respiratory diseases. The results show that in all three study households there is a good approximation between the observed and the simulated indoor temperatures. It was also observed a fairly consistent and realistic behavior between the simulated indoor and the outdoor temperatures, describing the Arquitrop model as an efficient estimator and good representative of the thermal behavior of households in the city of Sao Paulo. The worst simulation is linked to the poorest type of construction. This may be explained by the bad quality of the construction, which the Architrop could not simulate adequately.

Downward longwave radiation estimates for clear and all-sky conditions in the Sertozinho region of So Paulo, Brazil

The accurate estimate of the surface longwave fluxes contribution is important for the calculation of the surface radiation budget, which in turn controls all the components of the surface energy budget, such as evaporation and the sensible heat fluxes. This study evaluates the performance of the various downward longwave radiation parameterizations for clear and all-sky days applied to the Sertozinho region in So Paulo, Brazil. Equations have been adjusted to the observations of longwave radiation. The adjusted equations were evaluated for every hour throughout the day and the results showed good fits for most of the day, except near dawn and sunset, followed by nighttime. The seasonal variation was studied by comparing the dry period against the rainy period in the dataset. The least square linear regressions resulted in coefficients equal to the coefficients found for the complete period, both in the dry period and in the rainy period. It is expected that the best fit equation to the observed data for this site be used to produce estimates in other regions of the State of So Paulo, where such information is not available.

Anthropogenic heat in the city of So Paulo, Brazil

The main goal of this work is to describe the anthropogenic energy flux (Q (F)) in the city of So Paulo, Brazil. The hourly, monthly, and annual values of the anthropogenic energy flux are estimated using the inventory method, and the contributions of vehicular, stationary, and human metabolism sources from 2004 to 2007 are considered. The vehicular and stationary sources are evaluated using the primary consumption of energy based on fossil fuel, bio fuel, and electricity usage by the population. The diurnal evolution of the anthropogenic energy flux shows three relative maxima, with the largest maxima occurring early in the morning (similar to 19.9 Wm(-2)) and in the late afternoon (similar to 20.3 Wm(-2)). The relative maximum that occurs around noontime (similar to 19.6 Wm(-2)) reflects the diurnal pattern of vehicle traffic that seems to be specific to So Paulo. With respect to diurnal evolution, the energy flux released by vehicular sources (Q (FV)) contributes approximately 50% of the total anthropogenic energy flux. Stationary sources (Q (FS)) and human metabolism (Q (FM)) represent about 41% and 9% of the anthropogenic energy flux, respectively. For 2007, the monthly values of Q (FV), Q (FS), Q (FM), and Q (F) are, respectively, 16.8 +/- 0.25, 14.3 +/- 0.16, 3.5 +/- 0.03, and 34.6 +/- 0.41 MJ m(-2) month(-1). The seasonal evolution monthly values of Q (FV), Q (FS), Q (FM), and Q (F) show a relative minimum during the summer and winter vacations and a systematic and progressive increase associated with the seasonal evolution of the economic activity in So Paulo. The annual evolution of Q (F) indicates that the city of So Paulo released 355.2 MJ m(-2) year(-1) in 2004 and 415.5 MJ m(-2) year(-1) in 2007 in association with an annual rate of increase of 19.6 MJ m(-2) year(-1) (from 2004 to 2006) and 30.5 MJ m(-2) year(-1) (from 2006 to 2007). The anthropogenic energy flux corresponds to about 9% of the net radiation at the surface in the summer and 15% in the winter. The amplitude of seasonal variation of the maximum hourly value of the diurnal variation increases exponentially with latitude.

Agribusiness Opportunity Costs and Environmental Legal Protection: Investigating Trade-Off on Hotspot Preservation in the State of So Paulo, Brazil

Prior to deforestation, So Paulo State had 79,000 km(2) covered by Cerrado (Brazilian savanna) physiognomies, but today less than 8.5% of this biodiversity hotspot remains, mostly in private lands. The global demand for agricultural goods has imposed strong pressure on natural areas, and the economic decisions of agribusiness managers are crucial to the fate of Cerrado domain remaining areas (CDRA) in Brazil. Our aim was to investigate the effectiveness of Brazilian private protected areas policy, and to propose a feasible alternative to promote CDRA protection. This article assessed the main agribusiness opportunity costs for natural areas preservation: the land use profitability and the arable land price. The CDRA percentage and the opportunity costs were estimated for 349 municipal districts of So Paulo State through secondary spatial data and profitability values of 38 main agricultural products. We found that Brazilian private protected areas policy fails to preserve CDRA, although the values of non-compliance fines were higher than average opportunity costs. The scenario with very restrictive laws on private protected areas and historical high interest rates allowed us to conceive a feasible cross compliance proposal to improve environmental and agricultural policies.

Renovação e gestão de idades: experiências participativas no centro histórico de São Paulo

A questão dos centros metropolitanos ganha importância cada vez maior para as nações nesta virada de milênio. Os projetos de revalorização das áreas centrais das cidades transformaram-se em uma das funções básicas dos governos, pelo consenso de que a reorganização espacial está intimamente relacionada aos sistemas de produção econômico-político-sociais da atualidade. Desse modo, as cidades representariam possíveis plataformas de desenvolvimento econômico e promoção da inclusão social mediante a geração de empregos e de renda. Essa abordagem sugere uma reflexão sobre o dilema do desenvolvimento urbano x inclusão social, enorme desafio diante das tendências excludentes, cada vez mais acentuadas, em especial nos países emergentes. A integração entre as esferas pública e privada em experiências participativas é outra questão a avaliar, principalmente em sociedades com processos democráticos ainda não totalmente consolidados. O presente estudo tem por objetivo analisar as experiências participativas de renovação e de gestão do Centro Histórico de São Paulo por meio dos projetos estratégicos, seus desdobramentos e resultados, sob a ótica das organizações contemporâneas, com destaque para as ações coletivas e o exercício da cidadania. A importância que assumiram as metrópoles – que atraem um contingente humano sempre maior e, em sua esteira, os dilemas da atualidade – justifica a oportunidade do estudo proposto.
