La práctica del reciclaje. Estudio de caso de La Asociación Colombiana de Recicladores Independientes, UPZ Engativá-Bogotá D.C.

El interés de este estudio de caso es analizar los procesos de reciclaje que lideran la Asociación Colombiana de Recicladores Independientes (ACOREIN) en la Unidad de Planeamiento Zonal (UPZ) 74- Engativá, relacionándolos con las perspectivas de ciudad sostenible. Por tal motivo en el primer apartado, se describe y analiza el concepto de sostenibilidad, desarrollo sostenible, y ciudad sostenible, la cual se encuentra ejemplificada. En el segundo capítulo se describe la labor de reciclaje gestionada por ACOREIN, más específicamente en su centro de acopio -El Porvenir-, ubicado en la UPZ 74. Para ello, se analiza el papel de los recicladores, los bodegueros, los residentes, la historia del reciclaje, entre otros aspectos, dentro de la cadena del reciclaje. En el tercer capítulo se establecen unas relaciones a partir de las perspectivas de la ciudad sostenible, y de la experiencia de ACOREIN, dando paso a las conclusiones del proyecto.

The incidents of housing policies in the process of nesting the urban space (Buenos Aires, 1870-1999)

This article describes the housing policies displayed historically in B.A. that affected the processes of configuration and of giving hierarchy to the urban space. Since the process of modernization of B.A., at the end of the XIXth century, housing measures, urbanistic projects and political decisions have influenced the building of the city and the space distribution of their inhabitants: in this way, they have integrated some people and excluded others. No wonder, that, historically, popular sectors have established themselves in the South of the city (and in outskirt villages). These zones have been disregarded by the state, which has invested less in these areas. We will see how the connection between state housing policies and the population redistribution in the city, confirms the persistence of a strong process of urban and residential segregation that tends to expel the inhabitants of popular sectors and to attract the ones of the middle-class and high class sectors.

Mobilidade espacial nas Metrópoles Brasileiras: complexidade do espaço urbano

As transformações na dinâmica demográfica ocorrida nas últimas décadas nos espaços urbanos passam, em grande medida, pela reconfiguração territorial, econômica e social das áreas metropolitanas, na qual os movimentos das pessoas exercem influência fundamental. Para este trabalho, propomos uma abordagem sobre o movimento migratório intra-metropolitano em 14 áreas metropolitanas brasileiras, quais sejam: Belém, Belo Horizonte, Brasília, Campinas, Curitiba, Florianópolis, Fortaleza, Goiânia, Porto Alegre, Recife, Rio de Janeiro, Salvador, São Paulo e Vitória; questionamos se este fenômeno estaria alterando a histórica “pressão pelas áreas centrais metropolitanas” ou se essa população está mudando de residência, mas continua trabalhando no núcleo. Pensando sobre os movimentos da população ocupada nas regiões metropolitanas, buscamos ainda considerar os tipos de movimentos realizados (núcleo-periferia; periferia-núcleo e periferia-periferia) com uma caracterização desta população. Portanto, nossa reflexão está relacionada às diferentes lógicas que operam sobre o lugar de moradia das pessoas e os lugares de outros fazeres que determinam a vida urbana, especialmente o lugar de trabalho. A localização dos postos de trabalho em áreas mais “centrais” e a quantidade considerável de pessoas que se deslocam para estes municípios também são fenômenos expressivos ainda. Será que os movimentos cotidianos podem se apresentar como uma alternativa para a residência em outras áreas da metrópole e o trabalho nas áreas centrais? Nossa proposta é a de que esses processos precisam ser analisados cada vez mais em conjunto com a migração intra-metropolitana.

Intervención estatal en el mercado del suelo urbano. La reconstrucción del Eje Cafetero: el caso de Armenia

A raíz del pavoroso terremoto que tuvo lugar en el Eje Cafetero colombiano en 1999, que causógrandes pérdidas humanas y una gran destrucción, sobre todo del inventario inmobiliario, hubo ungran movimiento nacional de solidaridad tanto estatal como privado para socorrer las víctimas. Elprincipal rubro fue de recursos en la forma de subsidios a los afectados para que compraran nuevasviviendas, pero no se tomaron precauciones con respecto al mercado de tierras, a pesar de que lalegislación tiene valiosos instrumentos de gestión del suelo. En este estudio se hace una estimacióndel monto de estos subsidios que en realidad fueron apropiados por los propietarios de los terrenos,en la forma de elevación de precios del suelo y no por los damnificados. El caso es interesante porquelo observado tal vez pueda aplicarse al sistema general de subsidios de vivienda que constituyeel eje central de la política gubernamental

Informal access to urban land. Housing policies devoted to vulnerable sectors implemented in Cordoba-Argentina

The urban growth in Latino American cities, in a neoliberal context, has led to several population groups to having no possibilities to the access to urban land. Informal and irregular urban settlements increase, requiring attention from local governments, with actions and strategies in order to achieve both the regularization of such situation and further prevention. In the city of Córdoba different informal and irregular operations have taken place promoted by different actors. Furthermore, policies focused on regularization which have been promoted, have few intervention mechanisms, a fact that becomes critical, especially for the urban problems it causes. The main aim of this article is to present a classification over different modes of urban land acquirement taking place out of both urban and civil legislations. Afterwards, different informal settlement typologies are described, as well as the policies focused on them, together with their respective effects and impacts.

Manejo del arbolado urbano en Bogotá

Urban tree management in the city of Bogotá has become particularly important because it has been greatly affected by the District urban renovation and also because it is a high risk source due to the worrying physical and sanitary conditions of most of them, which result in many and frequent accidents for falling of branches or the whole structure. Since 1998, Bogotá established an institutional, legal, and technical order for the proper management of the urban woodland coverage and for ensuring thereby its survival in appropriate conditions that allow them to coexist with the urban infrastructure. This document presents the details that enabled such organization, reviews the statistics resulting from addressing the silvicultural topic in the city, and establishes a new starting point for its management based on the tree inventory as a planning tool.

Base de Datos Urbano – Arquitectónica: herramienta para la comprensión histórica y la interpretación estilística de Maracaibo.

In the Venezuela cities, and particularly in Maracaibo, the dynamics has caused the deterioration, transformation, or desappearence of architectural works of cultural interest. In order to rescue the urban and architectural image that has characterized the city of Maracaibo in the last 50 years, a case-study approach was used in the analysis of the main artery called Avenida las Delicias.

Rearrangement of the urban space in the sector of Saint Victorino and Saint Ines (Bogota) in relation with the dynamics of informality and marginality (1948-2010)

The present article analyze the urban transformations happened in the sector of Saint Victorino and Saint Ines in the city of Bogota D.C. between 1948 and 2010, making use of the "Genealogical Methodology" during the process of inquiry that allow to contrast the visions that are usually accepted of "progress" and "urban renovation" in the urban market context by the existence of a informal economic and a population in conditions of marginality that configures a good part of the "popular urban culture" of the Bogota in the 20th and 21st century. This vision permit to observe from various perspectives the changes that happened in this sector of the city, the impacts of the history facts occurred en this time period and, in special, the real effects of a rearrangement urban process that began in 1998 and has been prolonged to date, which has left a significant mark about the urban and social physiognomy of the place.

Formas de poblamiento y desigualdades en los desplazamientos. La evolución de la movilidad cotidiana en dos periferias populares de Bogotá: Soacha y Madrid (1993-2009)

Este estudio trata sobre la evolución de la movilidad cotidiana en dos municipios que ilustran la diversidad de las periferias populares de Bogotá: Soacha está integrado al mercado residencial y laboral de Bogotá, mientras Madrid conserva cierta autonomía. Ambos han entrado hoy día en una fase de “maduración urbana”, que se traduce en una diversificación de su composición demográfica, en una consolidación de lo construido, en un cierto arraigo residencial de sus habitantes y en un mejoramiento de la oferta local de empleos y servicios, entre los que se encuentra el de educación. El análisis de los censos realizados por el Departamento Administrativo Nacional de Estadísticas (DANE) en 1993 y 2005 y de unas encuestas específicas sobre movilidad (1993, 2009) muestra una relativa homogeneización de la composición social de los municipios, la cual contrasta con el recrudecimiento de las desigualdades de movilidad cotidiana, particularmente en Soacha. Estas desigualdades nos solo reflejan las jerarquías sociales, s  o también los efectos del género y de la edad, pues se observan diferencias importantes entre individuos de un mismo hogar.

Interaction between Public Transportation and Urbanization in the Mexico City Metropolitan Area: an Expansive Model Reaching its Limits

In Metropolitan Area of Mexico City, most of urban displacements happen through semi formal public transportation: small and medium capacity vehicles operated by small private enterprises, through a concession scheme. This kind of public transportation has been playing a major role in the Mexican capital. On one hand, it has been one of the conditions for urbanization to be possible. On the other hand, despite its uncountable deficiencies, public transportation has allowed for a long time the whole population to be able to move within this huge metropolis. However, that important function with regards to integration has now reached its limits in the most recent suburbs of the city, where a new mode of urbanization is taking place, based on massive production of very big social housing gated settlements. Public transportation tends to constitute here a factor of exclusion and households meet with important difficulties for their daily mobility.
