[pt] A Prefeitura de Bogotá, publicou em 2015 o Plano Urbanístico do Centro Ampliado de Bogotá (PUCAB) cujo objetivo principal era diminuir a segregação socioespacial evidente nos limites geográficos da cidade, onde nas periferias habita a classe socioeconômica baixa, e no centro da cidade habitam as classes média e alta, ao mesmo tempo em que é almejado o adensamento da cidade, alocando pessoas num número equivalente ao aumento populacional para o ano 2020 no setor analisado e delimitado geograficamente sob condições de mobilidade de tempos de chegada aos polos de emprego em máximo 20 minutos nos transportes públicos e 10 minutos a pé até as estações dos sistemas coletivos, isso desde qualquer ponto dentro do setor do Centro Ampliado. A partir do objetivo geral de alocar pessoas de classe socioeconômica baixa no centro da cidade e, das variáveis de delimitação geográfica, deduz-se a intensão de alocar à população adensada em zonas em que são permitidos os percursos curtos lar-trabalho-lar, de onde surge a hipótese de tese do não cumprimento de tempos máximos de 20 minutos nos transportes públicos ainda submetidos ao transito veicular no setor do PUCAB; comprovação feita com base nas pesquisas da Secretaria Distrital de Mobilidade (2015). Avalia-se o limite geográfico do setor do PUCAB e se apresentam metodologias de priorização de adensamento em zonas em que são permitidos os deslocamentos curtos das casas à maior oferta de emprego e, outras atividades habituais dos cidadãos. / [en] The Bogota Humana series (2015) published a book entitled Urbanistic Plan for the Enlarged Bogota s Downtown (PUCAB in Spanish) aimed at turning Bogota into a more egalitarian and environmentally friendly city, with spaces where sustainable mobility is promoted. Among other objectives, the book proposes a structured densification of the historical downtown and nearby sectors of Bogotá, the Colombian capital city. The project intended to mitigate the existing sociospatial segregation characterized by low class people living towards the city periphery and middle-high classes living in the so-called Enlarged Downtown. The search for social inclusion should be promoted in Bogota by forcing spatial inclusion, i.e., by dislocating low class population to central areas equipped with better public facilities (TORRES et al. 2009). The dislocated population will benefit from subsidies programs similar to the ones they now receive. The advantages of concentrating low class residences close to high employment areas are obvious as most of these people have precarious labor conditions and commute long distances (ALCALDÍA DE BOGOTÁ, 2015). The economy of Bogota is mostly based in factories and sales, which employ low class employers (GUTIÉRREZ, 2011). This fact underscores the convenience of dislocating these people who presently commute mostly from the periphery, so that they can get better access to jobs with shorter commutes, and eventually to other job offers. The densification initiative is understood as an activity that precedes economic growth for the city and the country, while improving urban mobility through decreasing pendulum-like tides, originated by people who live in the periphery and work downtown. Though urban zoning is coherent with the Urban Plan main goal regarding socio-spatial segregation, it is not part of the land zoning variables defined in the same document. Because of this, there is a discussion about the environmental and socio viability of densifying the enlarged Bogota downtown. The discussion is mentioned but scarcely analyzed in the Urban Plan.

La evolución es intrínseca en el ser humano y con nosotros evoluciona nuestro entorno. La industria de la construcción a manos de la necesidad del hombre, busca no solo un crecimiento horizontal territorial, sino también uno vertical. Sin embargo, esta proyección en las alturas se limita a una gestión plenamente espacial con poco interés en la capacidad de tránsito y zonas de refugio del agente humano durante un evento sísmico. Esta investigación realiza una evaluación de un escenario real existente del tramo de la avenida en estudio y el análisis de escenarios hipotéticos con variación del ancho de la zona de refugio. De este modo, se propone valores límite de altura y densidad poblacional de edificaciones para una Gestión Prospectiva del Riesgo Sísmico teniendo como ejemplo base un tramo de la Av. San Felipe en Lima-Perú. Se realizó el análisis de una evacuación eficiente de las edificaciones hacia la zona de refugio con modelos basados en el agente con el software Pathfinder, modelos tridimensionales (BIM), se analizó tiempos de evacuación, la influencia de las edificaciones, comportamiento humano y los parámetros urbanísticos zonales. Los resultados del presente trabajo establecen gráficamente la pertinente relación directa de la altura máxima permisible de los edificios proyectados con el ancho de la zona de refugio para una correcta evacuación. Como ejemplo se tiene un tramo de la Av. San Felipe con 7m de ancho de la zona de refugio correspondiente a 18 pisos como altura límite en los 10 edificios adyacentes considerando una longitud frontal total de 144m. / Evolution is intrinsic to human beings and our environment evolves with us. The construction industry at the hands of man's need, seeks not only a territorial horizontal growth, but also a vertical one. However, this projection in the heights is limited to a fully spatial management with little interest in the transit capacity and refuge areas of the human agent during a seismic event. This research carries out an evaluation of a real existing scenario of the section of the avenue under study and the analysis of hypothetical scenarios with variation in the width of the refuge area. In this way, limit values ​​of height and population density of buildings are proposed for a Prospective Management of Seismic Risk, taking as a base example a section of Av. San Felipe in Lima-Peru. The analysis of an efficient evacuation of the buildings towards the refuge area was carried out with models based on the agent with the Pathfinder software, three-dimensional models (BIM), evacuation times, the influence of the buildings, human behavior and the parameters were analyzed. zonal urban planning. The results of the present work graphically establish the pertinent direct relationship of the maximum permissible height of the projected buildings with the width of the refuge area for a correct evacuation. As an example, there is a section of Av. San Felipe with a 7m width of the refuge area corresponding to 18 floors as the limit height in the 10 adjacent buildings considering a total frontal length of 144m. / Tesis

När man inom stadsplanering strävar efter att förtäta städer och urbana miljöer blir balansen mellan stad och natur allt viktigare, särskilt som befolkningen växer och behovet av täta städer lika så. Också medvetenheten om funktionerna i dessa grönområden blir betydelsefulla när naturen och dess tjänster ska planeras in som resurser i samhället på en begränsad yta. För att bevara de många värden och ekosystemtjänster som naturen tillhandahåller åt samhället behöver dessa områden skötas på ett lämpligt sätt. Syftet med denna studie är att undersöka naturvård med hjälp av häst i urbana miljöer och de värden det skapar. Vidare utreds hur naturvård kan skapa förutsättningar för olika ekosystemtjänster och gröna värden. Som metod användes en litteraturstudie och en fallstudie bestående av intervjuer och en dokumentstudie med granskning av plandokument. Slutsatsen som drogs från studien är att naturen skapar många värden – ekologiska, sociala och ekonomiska – för samhället och att dessa behöver tas omhand för att samtliga värden ska kunna åtnjutas även framöver. Naturvård med häst är ett på många sätt effektivt sätt att sköta natur och grönområden och därigenom bevara och utveckla de värden och tjänster för vidare nyttjande. Naturvård med häst bidrar även i sig med sociala och pedagogiska värden då djuren är uppskattade av människor och det stimulerar lärande och ny kunskap. Naturvård med häst kan bli mer kostsamt än andra metoder beroende på beställd åtgärd när entreprenör anlitas men vinsterna i de olika värdena anses kunna väga upp den kostnaden. Det finns många värden att hämta från att integrera häst i naturvården helt eller delvis. / In urban planning, there is currently a challenge with keeping the balance between the urban city and the surrounding nature, especially as the population grows and with it the need of cities with high densities. The increasing awareness of the functions that the urban greenspaces provide is important as ecosystem services are planned as resources for the city on a very limited area. To be able to conserve and develop the values and ecosystem services provided by nature it needs to be taken care of in a suitable way. The aim of this study is to investigate urban nature conservation methods with the use horses and what values these methods provide. Also, the conditions for ecosystem services and green values created by nature conservation are investigated. The methods used are a literature study as well as a case study consisting of interviews and a document study.   The conclusion made from the study is that nature provides many values, both ecologic, social and economic, and these values are in need of proper nature conservation to be able to persist and develop in the future. Nature conservation with horses is an effective way to manage nature and maintain and develop values and services in the future. It also provides social and pedagogical values as the horses are appreciated by people and they stimulate learning and taking in new knowledge, especially about nature and ecosystem services. Nature conservation with horses seems more expensive than other methods, depending on the service executed by hired contractor. The gains in the many conserved values are however considered higher than the costs. There are many values that can be acquired by integrating the use of horses in nature conservation, either as a whole or partial.

A efervescência da cidade moderna somente é possível devido ao deslocamento contínuo de pessoas e mercadorias. A movimentação de bens é trivial para a realização das atividades comerciais, industriais e de prestação de serviços. Sua demanda, entretanto, é condicionada pelos padrões de uso e ocupação do solo e adensamento urbano. Esta pesquisa aborda aspectos da relação entre o transporte urbano de carga e a estruturação das áreas urbanas no Brasil. O principal objetivo é analisar a influência mútua entre a logística urbana e o uso e ocupação do solo no desenvolvimento de áreas urbanas no Município de São Paulo. Dessa forma, foram identificados, selecionados e analisados abordagens, metodologias e modelos aplicáveis à análise e proposição de diretrizes que integrem os condicionantes de desenvolvimento urbano e de transporte urbano de carga. Um modelo selecionado, o Freturb, foi aplicado em um recorte urbano do Município de São Paulo. Localizada na região de Santa Cecília e Higienópolis, a área de estudo foi modelada, primeiramente, de acordo com a sua configuração urbana atual e, em seguida, com as suas predições urbanas para os anos de 2025 e 2030, conforme os parâmetros urbanísticos do novo Plano Diretor Estratégico de São Paulo, em vigor desde 2014. Os resultados da modelagem foram abordados, qualitativamente, sob três categorias, que organizam parâmetros de planejamento e que se inter-relacionam no ambiente urbano: Aspectos do Uso e Ocupação do Solo, Aspectos da Logística e Aspectos do Tráfego Urbano. O trabalhou comparou, ainda, os resultados da configuração urbana atual do recorte urbano de São Paulo, com áreas urbanas francesas, selecionadas no Centro de Lyon e no 4o. Arrondissement de Paris. Essa comparação permitiu analisar a relação entre a empregabilidade e a densidade de movimentos da carga, nas três regiões urbanas. O estudo revelou que a área estudada em São Paulo necessita de mais movimentação de carga e exige mais do viário urbano e/ou é suprida por sistemas logísticos menos organizados, em relação às duas áreas francesas. Ainda, o porte e o perfil do estabelecimento podem incrementar o tempo de carga e descarga em uma área urbana. Finalmente, as predições urbanas, de 2025 e 2030, motivadas pelo novo Plano Diretor Estratégico do Município de São Paulo, permitiram avaliar e compreender os possíveis impactos do adensamento populacional e de empregos na demanda por transporte urbano de carga. E, verificar os possíveis impactos associados, tais como incremento em paradas em \"fila-dupla\" e ocupação viária por veículos de carga. / The effervescence of the modern city is only possible due to the continuous movement of people and goods. The movement of goods is trivial for of commercial, industrial and service activities. However, it is conditioned by the patterns of land use and urban density. This research approaches aspects of the relation between the urban freight transport and the structuring of urban areas in Brazil. The main objective is to analyze the mutual relationship among urban logistics and urban land use parameters on developing urban areas in São Paulo. Thus, applicable approaches, methodologies and models were identified, selected and analyzed, in light of their potential to support the integration of urban development and urban freight transport conditions. A selected model, the Freturb, was applied in an urban area in the city of São Paulo. Located in the region of Santa Cecilia and Higienopolis, the case study area was modeled, firstly, according to its current urban setting and then with their urban predictions for the years 2025 and 2030, according the new parameters of Master Plan of São Paulo, approved in 2014. The modeling results were classified and discussed accordingly to three aspects: Land Use Aspects, Logistics Aspects and Urban Traffic Aspects. The research also compared the results of the case study area located in São Paulo with other French urban areas, selected in the Center of Lyon and 4th. Arrondissement of Paris. Such a comparison allowed analyzing the relationship between the employability and the density of freight movements, in the three urban areas. The research revealed that the area in São Paulo requires more freight movement and urban road space and/or is supplied by less organized logistics systems, with regard to the latter two French areas. Also, the size and profile of the establishment can increase the loading and unloading time of operation in an urban area. Finally, the urban predictions, 2025 and 2030, motivated by the new Master Plan of São Paulo, allowed evaluating and understanding the possible impacts of population density and employment in demand for urban freight transport. And, they also allowed verifing the possible associated impacts, such as the increase in stops at \"double-park\" and road occupancy by goods vehicles.

Les immeubles de grande hauteur (IGH) sont des constructions symboliques liées, le plus souvent, aux problématiques de la rareté du foncier, aux défis de la densification urbaine dans les grandes villes et aussi au questionnement de la construction durable. Pourtant, un IGH ne se limite pas seulement à ces seuls points :quel impact en terme de risque représente un IGH sur son environnement ?Quelle démarche d'analyse d'un éventuel péril lié à la présence de ces constructions sur leur environnement faut-il considérer ?<p><p>La conception d'un IGH ne peut être effectuée sans une analyse des risques engendrés par la présence de tels immeubles sur leur environnement et sur le développement urbain. En effet, quand un événement indésirable y survient, un IGH peut se révéler être une menace pour ses occupants et son <p>voisinage immédiat. Les IGH sont des immeubles où plusieurs centaines de personnes sont présentes, ce qui engendre de nombreuses contraintes au niveau de la sécurité incendie notamment. En cas d'accident comme un incendie, diverses matières toxiques peuvent être libérées dans l'atmosphère, endommageant l'environnement de l'immeuble.<p><p>C'est ici que peut intervenir une méthode d'analyse des risques environnementaux permettant à un expert d'évaluer différentes situations envisagées pour l'immeuble même et son environnement. Le modèle proposé est une nouvelle méthode quantitative issue d'une approche semi-quantitative. Des matrices d'évaluation et une formulation quantitative permettent de quantifier le risque environnemental. Ce risque est déterminé pour différents secteurs autour de l'IGH car chaque environnement étudié est hétérogène et différent.<p><p>La méthode proposée reprend un ensemble de paramètres déterminés à l'aide de critères d'évaluation et de paramètres géométriques tels que la différence d'altitude entre les immeubles, la distance, etc. Nous verrons comment ces paramètres influencent le modèle et l'analyse de risques environnementaux. Un ensemble de simulations numériques seront effectuées sur un panel de cas d'études simples afin de valider le programme. Deux IGH actuellement détruits ont été étudiés avec pour objectif de comparer les résultats obtenus avec la réalité de la situation ainsi que les différentes propositions correctives. Pour chaque étude, des critiques et commentaires seront produits afin de se rattacher à la réalité des situations décrites.<p><p>The high-rise buildings (HRB) are symbolic constructions linked most often to scarce building lands, urban density challenges for big cities and the problematic of sustainable construction. However, an HRB is not limited to just these items alone: what risk impact does an HRB have on the environment? What analysis method of possible risk on the environment is to be considered for the presence of constructions?<p><p>HRB design cannot be done without any environmental risk assessment for such buildings on their environment or their impact on urban development. When an unwanted event occurs, an HRB can be a threat to its occupants and its immediate vicinity. The presence of large numbers of people in those building definitely generates a lot of problems at the level of fire safety, for example. Accidents such as a fire can release toxic materials, which will thus impact the environment of the building.<p><p>In such circumstances, a method of analysis of environmental risks come useful to experts to assess the different situations to be considered for the building itself. The proposed model is a new quantitative method which is the result of a semi-quantitative approach. Quantifying the environmental risk is made possible by evaluation matrices and quantitative formulation. This risk is determined for various sectors around HRB because every environment is heterogeneous and different.<p><p>The proposed method incorporates a set of parameters which were determined by means of evaluation criteria and geometrical parameters such as the difference in height between the buildings, distance, etc. We will see how these parameters affect the model and analysis of environmental risks. A set of simulations are performed on a range of simple models to validate the program. Two HRBs which have now been demolished were studied so as to compare the results obtained with the real-life of the situation and the corrective different proposals. For each study, criticism and comments will be produced to relate to the reality of the situations which has been described.<p> / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished
