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

Se identifican los patrones del crecimiento urbano de la ciudad de Chillán (Chile Central), el uso del suelo asociado a cada uno de ellos y los factores que guían el proceso de expansión urbana. Se cuantificaron los cambios en la superficie urbana construida en un período de 57 años (de 1943 hasta el 2000). Entre 1997 y el año 2000, se analizó el cambio en relación con el uso del suelo, la densidad de población y la condición socio-económica de los hogares. Se utilizaron fotografías aéreas, SIG (Arcview 3.2 y Arc-Info N.T) e índice de análisis espacial (Spatially Explicit Landscape Index).

The settlement of P.T.E., the Multifunctional Centre to serve the Nautical and Technological District of North-East Sardinia, situated on a stretch of coastline north of the Gulf of Olbia, forces us to think about what kind of relationship could be established between the architecture and surrounding environment, strongly characterized on an urbanistic and landscape level. The extension of the productive area denotes the hard strokes of the intensive anthropization of the land, in one of the most beautiful and evocative places in the Gulf.

La temprana y radical liberalización de los mercados urbanos chilenos tuvo consecuencias inesperadas en los precios del suelo y en la segregación residencial en Santiago: los precios del suelo ha crecido persistentemente desde la eliminación en 1979 de la norma sobre "límites urbanos" y otras reformas; y la segregación ha reducido su escala geográfica en importantes áreas, debido a la acción del robusto sector inmobiliario privado surgido en los años ochenta.

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.
