Parce qu'elles concentrent plus de la moitié de la population et l'essentiel de l'activité économique mondiales, les villes sont des acteurs majeurs des problématiques environnementales globales. Les politiques de transport, d'urbanisme et de logement sont ainsi reconnus comme des moyens nécessaires et efficaces d'action pour réduire les émissions ainsi que pour réduire la vulnérabilité aux impacts du changement climatique. Jusqu'à présent, malheureusement, il n'y a pas de consensus sur ce qui doit être fait, et encore moins sur comment le faire. Trois difficultés, au moins, expliquent cela. Tout d'abord, les politiques climatiques interagissent avec les autres objectifs des politiques urbaines, comme la compétitivité économique ou les problèmes sociaux, entrainant des synergies et des conflits. Ensuite, les inerties sont un facteur-clef à prendre en compte : les modifications structurelles des villes s'opèrent très lentement. Si l'on veut que les villes soient adaptées au climat de la fin du XXIème siècle, il est indispensable de commencer à agir dès maintenant. Enfin, les effets des politiques urbaines dépendent de nombreux facteurs exogènes, et inconnus au moment où la décision doit être prise : les changements démographiques, socio-économiques culturels politiques et technologiques vont jouer un rôle majeur. Ces trois difficultés ne sont cependant pas insurmontables, et nous illustrerons comment une modélisation intégrée peut permettre de répondre à une partie de ces problèmes / Because they are home to more than half of the world population, and because most of the world economic activity takes place within them, cities are at the forefront of global environmental issues. Land use planning, urban transport and housing policies are now recognized as major tools for the reduction of both greenhouse gases emissions and vulnerability to climate change impacts. So far, however, how to use these tools efficiently remains unclear. At least three main difficulties explain this, and play a key role in urban climate policies analysis. First, urban climate policies are also not developed or implemented in a vacuum; they interact with other policy goals, such as economic competitiveness or social issues, giving rise to both synergies and conflicts. Second, inertia is a key factor when designing optimal climate policies : structural modifications in cities occur slowly over a long time horizon. Some immediate actions are required if cities are to be adapted to a different climate or to help reduce greenhouse gases emissions within a few decades. Third, the evolution of a city depends on several external factors, on which local policy-makers do not generally have much influence : demographic, socio-economic, cultural, political and technological changes will play a major role. This uncertainty has to be taken into account, and climate policies have to be robust against future possible global evolutions is important. These three difficulties are not, however, impossible to overcome, and we will illustrate how integrated city modelling can help address these issues

A discourse submitted to the Faculty of Architecture, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the degree of Master of Science in Development Planning. Johannesburg, 1991 / During the 1980s considerable attention was focused on the need to develop institutions to draw populations into development efforts. Local government was the recipient of much of this attention. This study is concerned with the role of local government in development, and problems that are experienced in playing a developmental tole. In particular, it is concerned with international experience of local government as a development institution, and the relevance of that experience to SA. [No abstract provided.

Neste trabalho, utilizamos uma equação hedônica para estimar o preço implícito de amenidades urbanas a partir de dados do mercado de imóveis no Município de São Paulo. São testadas duas especificações: uma com as variáveis explicativas originais e outra com a construção de fatores para correção de multicolinearidade. Além de considerar a configuração monocêntrica tradicional, propomos a inclusão de um vetor de acessibilidade para o caso de uma cidade duocêntrica. A investigação sobre as variáveis ambientais relevantes é fundamentada na interpolação espacial dos resíduos. Concluímos que a proximidade das estações de trem, a presença de áreas verdes e o zoneamento estritamente residencial valorizam o imóvel para fins residenciais, enquanto a criminalidade reduz o seu valor. / In this work, I use a hedonic equation to estimate the implicit prices of urban amenities based on housing market data for the city of São Paulo. I test two different specifications, one with the original independent variables, and another with factors to correct for multicollinearity. In addition to the traditional monocentric model, I include an accessibility vector for a duocentric city. A criterion to select the appropriate environmental variables based on residual spatial interpolation is introduced. I conclude that proximity to train stations, green areas and strict residential zones raise rents, while criminality reduces them.

O objetivo desse trabalho é analisar a distribuição espacial do capital humano nos municípios Estado de São Paulo. Para tanto, será usada uma metodologia de investigação composta de regressões que buscam explicar a variação do capital humano municipal com base em seu estoque inicial e em outras variáveis de controle. Os resultados mostram que as pessoas com ensino superior possuem uma tendência apenas moderada de divergência espacial, que se desfaz gradativamente à medida que adicionamos novas variáveis de controle. Por outro lado, as pessoas com ensino básico ou analfabetas apresentam evidências muito mais concretas de convergência espacial. Esse resultado vai contra a literatura internacional da área que sugere existência de concentração espacial nas pessoas com alto capital humano. / This paper investigates the spatial distribution of the human capital in the municipalities of the Brazilian state São Paulo. For that purpose, a methodology consisted by linear regressions that aims to explain the human capital variations using control variables and the initial stock of human capital will be used. The result shows that people with college degrees have a moderate trend of spatial divergence, which is gradually undone once we put new control variables in the regression. On the other side, people with basic education or no education at all present a more robust trend of spatial convergence. This result is not supported by the international evidence of the area, which shows the existence of a strong spatial divergence trend in the people with high human capital.

O objetivo deste estudo é compreender se certas características espaciais influenciam o desempenho exportador das firmas. A análise é feita com dados de dezenove setores exportadores dos municípios do Estado de São Paulo, que compõem a maior Aglomeração Industrial Exportadora do país. Os resultados obtidos, com o Modelo de Determinantes das Exportações, confirmam a hipótese que fatores espaciais são relevantes para as exportações das firmas. Indo ao encontro de uma das previsões do Modelo de Krugman-Livas, a especialização econômica aparece como uma dos principais determinantes das vendas para outros países. Os efeitos das economias de aglomeração foram significantes para a maioria dos setores estudados. Tais resultados evidenciaram que as economias de urbanização, que já foram apontadas em diversos estudos como importantes para o crescimento das cidades, parecem também ser relevantes para as firmas que exportam. Notou-se ainda que transbordamentos espaciais dos diversos setores levam a efeitos representativos para as exportações. Além disso, a acessibilidade a mercados afeta os setores de maneira diferenciada. / The aim of this study is to understand if spatial aspects influence firms export performance. The analysis is made with data from nineteen exporting sectors of the state of São Paulo, which constitute the largest industrial export agglomeration of the country. The results obtained through the Export Determinants Model confirm the hypothesis that spatial aspects are relevant for firms exports. As it appears in Krugman-Livas Model, economic specialization seems to be a major determinant of sales to other countries. Agglomeration economies effects were significant for almost all sectors, showing that urbanization economies, which have already been identified in various studies as important for the growth of cities, also seem to be relevant to firms which export. It was also observed that spillover effects into the sectors are representative for exports. Furthermore, access to markets affects sectors in a different way.

A cidade de São Paulo, que abriga 11 milhões de habitantes, sofre constantemente os efeitos dos alagamentos provocados pelas precipitações intensas. Esses alagamentos ocorrem todo verão, em diversas partes da cidade. Além das perdas e inconvenientes sofridos pelos residentes, os alagamentos produzem prejuízos que ultrapassam as fronteiras da cidade, afetando a renda e o produto da região metropolitana, de outras partes do estado e do país. O objetivo desse estudo é avaliar os impactos econômicos dos alagamentos na cidade de São Paulo por meio do uso de um modelo espacial de Equilíbrio Geral Computável, integrado a informações georreferenciadas relacionadas à localização dos pontos de alagamento e às firmas dentro dos raios de influência. Estima-se que os alagamentos contribuem para a redução do crescimento da cidade e do bem estar de seus residentes, além de prejudicar a competitividade local nos mercados doméstico e internacional. Foi identificada uma taxa de dano intra-cidade de 2,1, e uma taxa de impacto total de 4,9 para a economia brasileira. / The city of São Paulo, home to 11 million people, suffers constantly the effects of flooding caused by extreme precipitation. Localized floods occur every summer in various parts of the city. Besides the losses and inconvenience felt by the residents, floods produce damages that cross the city boundaries, affecting income and output in the metropolitan area as well as in other parts of the state and the country. The objective of this study is to evaluate the economic impacts of floods in the city of São Paulo through the use of a spatial Computable General Equilibrium model integrated to GIS information related to the location of points of floods and the firms within their influence. It is estimated that floods contributed to reduce city growth and residents welfare, as well as to hamper local competitiveness in both domestic and international markets. An intra-city total impact-damage ratio of 2.1 and an economy-wide total impact-damage ratio of 4.9 were found.
