This paper presents a method to optimise the calibration of parameters and land use transition rules of a cellular automata (CA) urban growth model using a self-adaptive genetic algorithm (SAGA). Optimal calibration is achieved through an algorithm that minimises the difference between the simulated and observed urban growth.
The emergence of GIS and the availability of high resolution geographic data have improved our ability to investigate the residential segregation in cities and to identify the temporal changes of the spatial phenomena.
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.
Nowadays many seaside towns, economically based on marine tourism, need operations to reinvent and recovery their own image and to define a new strategy of urban development. The presence of the sea is of primary importance and it should be considered not only as an economic resource, but mainly as a strong element of identity that must interact with the urban landscape.
The present study assesses changes (1949-2008) in the structure of a Mediterranean urban area (Rome, Italy) in three phases (compact growth, medium-density growth, low-density growth) of its recent expansion which reflect different economic contexts at the local scale.
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.
Urbanization deserves urgent attention from policy makers, academics, entrepreneurs, and social reformers of all stripes. Nothing else will create as many opportunities for social and economic progress. The urbanization project began roughly 1,000 years after the transition from the Pleistocene to the milder and more stable Holocene interglacial.
The accumulation of decent housing matters both because of the difference it makes to living standards and because of its centrality to economic development. The consequences for living standards are far-reaching. In addition to directly conferring utility, decent housing improves health and enables children to do homework.
