Na cidade contemporânea, o ambiente construído vem se modificando, observandose a presença de áreas em transformação de uso e esvaziamento. Em São Paulo, a transformação do ambiente construído mediante esse processo, frente à dinâmica de ocupação do solo e reconfiguração de áreas pela via do mercado imobiliário, parece se consagrar como a principal força de produção do espaço urbano, apesar da existência de instrumentos urbanísticos de indução do desenvolvimento da cidade, articulado pela regulação do poder público municipal.

The short review of the space protection efficiency in European countries and in Serbia has been given. The role of instruments and measures of land policy and corresponding combinations of stimulative and destimulative instruments of economic and fiscal policy, with provision of programming and other support in efficient space protection and reservation in European countries has been investigated.

The implementation process of the Syracuse’s Master Plan is characterized by the widespread use of “urban negotiation”. The Muni- cipality has drawn up a protocol aimed at obtaining areas for facilities and public infrastructures in different areas basing on the rule of the transfer of a portion of land in return for the building permission for the remaining part. Since these areas are variously cha- racterized, the negotiation process may not be fair to Municipality or convenient to land owners.

Resumen

Resumo

Water policies have a great impact upon different types of resources (water, land and soil resources; infrastructure and facilities; financial resources; environmental knowledge and information; etc.). They involve many individual or collective actors (users, managers, public or private companies, associations, etc.) as well as rules and norms of behavior that these actors are the recipients or agents. Complex systems, if any, these policies have several kinds of effects, expected and unexpected, direct and indirect effects, societal, economic, environmental and eco-systemic.

This study investigates the process of globalization over the past decades as a process of technological progress in computer science and communication and as transformation in the world economic order. It identifies the political and economic causes of globalization and their impact on the social sphere of developing nations. In past decades social inequality has widened in these countries and their large cities. This article also identifies lifestyle changes in the city of São Paulo and their consequences in urban land occupation and use.

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.
