This paper analyses the main causes of the growth in population and employment in urban areas in Australia. We find that two-thirds of the variations in growth rates between 1981 and 1991 are explained by four factors: an inland location, a reliance on primary sector production, a tourist orientation, and suburban growth. Tourism and suburban growth greatly increased both population and employm...

This study presents a hybrid simulation model that combines logistic regression and cellular automatabased modelling to simulate future urban growth and development for the city of Ahmedabad in India. The model enables to visualize the consequence of development projections in combination with present zoning and development control regulations. The growth in activities’ floor space is projected...

this paper examines the application of a gis based planning support system, what if? tm, to evaluate alternative growth policies for sustainable urban growth in a rapidly growing city of iran. the paper describes the study area, dorood city, and the what if? model. it then explains the procedures that were used to obtain the required data and to run the model to dorood city. the paper concludes...

By 2050, 90% of the population in Latin America will live in cities, but there is a lack of up-to-date spatial information about the urban extent and patterns of urbanization in cities of this region. In this study, we analyzed population growth, urban density and urbanization dynamics between 1992 and 2009 in the major cities of Bolivia, Colombia, Ecuador and Perú using Google Earth and DMSP/O...

This study analyses the expansion of urban growth and land cover changes in five Saudi Arabian cities (Riyadh, Jeddah, Makkah, Al-Taif and the Eastern Area) using Landsat images for the 1985, 1990, 2000, 2007 and 2014 time periods. The classification was carried out using object-based image analysis (OBIA) to create land cover maps. The classified images were used to predict the land cover chan...

A particular challenge for undertaking urbanization mapping of Beirut is the absence of a unified understanding of the city. Migration, informal settlements, a lack of urban planning, political corruption, as well as internal conflict have made this task even harder. The population in Lebanon is unevenly distributed among regions, where one third of the population resides in the Greater Beirut ...

In this research, a constrained cellular automata (CA) model based on Artificial Neural Network (ANN) is developed to simulate and forecast urban growth. As we know, many factors impact urban growth, and relationships among them are complex and non-linear. In geographic CA research, models with different rules and symbology have been developed to simulate those relationships. Yet, in previous d...

BECAUSE THE YEAR 2000 figures prominently in urban population projections , it is timely to assess whether the United Nations' earliest projections of urban population growth in developing countries, made in the 1970s, have been reasonably accurate, and if not, why. Despite being accompanied by advice to interpret urban population projections with caution and not as forecasts (United Nations 19...

Abstract Using a spatial equilibrium model and data of 286 Chinese cities at the prefecture above- level from 2002 to 2013, this study estimates contribution each city national GDP growth. The results reveal several interesting patterns. First, what an individual contributes aggregate growth is not represented clearly by city's based on standard accounting calculation. Second, increased real wa...
