Resumen

Este artículo propone algunas reflexiones críticas sobre la tradición creciente de implementación de políticas públicas de regularización de asentamientos informales en áreas urbanas, con el objetivo de contribuir para que el proceso de crecimiento informal de las ciudades latinoamericanas sea enfrentado de manera más adecuada.

Berlin’s unification in the last 12 years was not only a political, social or civil task to be solved, but it was essential to go with a readable and coherent urban structure. This was attempted with the elaboration of the 'Planwerk Innenstadt', a structural land use plan for central Berlin covering an area of 30 km2. The urbanism and architecture practised in the last decade reflect the rigid and conservative aesthetics and inflexible guidelines of traditional European townbuilding, set up by the plan and the Senate.

Urban footprint refers to the proportion of paved surface (built up, roads, etc.) with the reduction of other land use types in a region. Rapid increase in the urban areas is the major driver in landscape dynamics with the significant erosion in the quality and quantity of the natural ecosystems. The urban expansion process hence needs to be monitored, quantified and understood for effective planning and the sustainable management of natural resources.

En las áreas metropolitanas europeas, la construcción de redes de infraestructuras, fundamentalmente las de transporte, está propiciando la extensión de expectativas urbanísticas a ámbitos territoriales cada vez más amplios, en los que se dan simultáneamente procesos de especialización por tipos de usos y de rentas.

Siempre que el aumento de la velocidad fuera proporcional con el aumento de la riqueza territorial, medida en sus índices de extracción y elaboración, se mantendría el equilibrio en las funciones económicas de los núcleos poblados, pero hasta la fecha [1936] y particularmente en territorios de colonización el aumento de la velocidad ha sido muy superior al incremento de la riqueza territorial.

The trans-European transport network has different effects at interregional macro-regional and mezzo-regional level, and its effectiveness rises at the lower regional levels. Possible approaches to the trans-European transport network impact and effect survey and policy options have been pointed out. In that respect the brief review of survies, strategic framework and policies in European Union has been given. The importance of increased accessibility and mobility for regional expansion and for more balanced and polycentric system of city networks has been underlined.

In many cities of Brazil, social inequality is illustrated by violence, poverty, and unemployment located next to luxurious residential towers and armored passenger cars. In the face of this situation, the National Movement of Urban Reform encouraged the inclusion of the social function of property in Brazil's new constitution of 1988. Surface rights represent an urbanistic instrument in the city statute that is best aligned to the constitutional principles and urban policies.

Se analiza la relevancia de los servicios ambientales de los corredores fluviales en el ámbito de la planificación urbana sustentable, al tenor de la realidad y falencias de los instrumentos territoriales vigentes en esta temática.

La innovación es la capacidad de generar e incorporar conocimientos para dar respuestas creativas a los problemas del presente. En la situación actual es vista como un factor clave para mejorar la competitividad de las empresas y favorecer el desarrollo sostenible en los territorios. Las pymes tienen una mayor dependencia del territorio, por lo que se analiza cuál es el efecto que la gestión del territorio por parte de las empresas tiene sobre su capacidad de innovación. Se evalúa el sistema de innovación de las pymes de Vigo y su área de influencia.

The topic of this paper is the presentation of the Martineau Place Commercial Centre project in Birmingham. Through detailed elucidations of the participants’ role (investor, project team, contractor) particular attention has been paid to the realization process of this significant development. The very complex project of construction value of just under 20 million and realized in the period of increased economic uncertainty in the years 2001 and 2002 has been envisaged within the framework of macro trends influencing its realization.

The problems of climate change significantly alter the character of urban planning. While changes in the planning process are aimed at mechanisms for urgent action in the transformed circumstances in the sense of a deeper understanding of the causes of phenomena and prediction of future changes, modification of specific measures suppose to be related to the regulatory framework for new and existing construction that will lead to reduction in carbon dioxide emissions and the development of resistance to settlements' extreme impacts.
