Managing and modelling urban growth is a multi-faceted problem. Cities are now recognised as complex systems through which non-linear and dynamic processes, emergence and self-organisation occur. The design of a system that can handle these complexities is a challenging prospect. This paper presents an urban planning tool for the city of Riyadh, Saudi Arabia. At the core of the system is a Fuzz...

This paper examines the impact of rural-urban migration on under-two mortality in India, using data from the 1992/93 Indian National Family Health Survey. Multilevel logistic models are fitted for mortality in three age groups: neonatal, early post-neonatal, and late post-neonatal and toddler. Migration status was not a significant determinant of mortality in any of the three age groups. Furthe...

The Land Transformation Model (LTM), which as been developed to forecast urban use changes in a grid-based geographic information system, was used to explore the consequences of future urban changes to the years 2020 and 2040 using non urban sprawl and urban sprawl trends. The model was executed over a large area containing nine of the major coastal watersheds of eastern Lake Michigan. We found...

OBJECTIVE To compare variety and diversity patterns and dietary characteristics in Guatemalan women. MATERIAL AND METHODS Two non-consecutive 24-h recalls were conducted in convenience samples of 20 rural Mayan women and 20 urban students. Diversity scores were computed using three food-group systems.Variety and diversity scores and dietary origin and characteristics were compared between set...

This article deals with the increasingly digital augmentation of urban space and looks at how so far initiatives in this sense have been deployed in a way that is disconnected from urban design knowledge and practice. The aim here is to contribute to a reflection on how urban design perspectives can – and should – play an important role in informing such developments. It promotes, through a ser...

We present our approach on how smart city technologies may enhance the learning process. We have developed the CLIO urban computing system, which invites people to share personal memories and interact the collective city memory. Various educational scenarios and activities were performed exploiting CLIO; in this paper we present the methodology we followed and the experience we gained. Learning...

Over 70% of the population in developed countries live in cities. World wide, the average urban population proportion is 42% (World population reference, 1993). Urbanization creates significant changes in land use and land cover, affecting the structure, pattern and function of the ecosystem. The public is increasingly concerned about how these changes influence our daily life and the sustainab...

Under the assumption of perfect competition, it is difficult to avoid the conclusion that abandoned properties and long undeveloped neighborhoods remain that way because they are unprofitable. In contrast, this paper introduces a model in which firms systematically overlook neighborhoods with little commercial activity because of a positive informational externality motivating later movers to c...

This chapter considers the literature on urbanization and migration to cities from rural areas in developing and middle-income countries. The chapter assesses recent patterns, discusses traditional models, addresses more recent models of migration, presents some of the recent findings from the micro-econometric literature, and closes with a discussion of the role of cities in economic growth. C...
