Rapid urbanisation is a major feature of developing countries. Some 2 billion more people are likely to become city residents in the next 30 years, yet urbanisation has received little attention in the modern development economics literature. This paper reviews theoretical and empirical work on the determinants and effects of urbanisation. This suggests that there are substantial productivity b...
Regional and Sub-Regional Population Dynamic Population Process in Urban Areas European Population Conference 21-24 June, 2006 Urbanization is an index of transformation from traditional rural economies to modern industrial one. It is a long term process. This paper endeavors to illuminate on the process of urbanization in India over a century with emphasis on level, tempo of urbanization and u...
Differences in asthma in urban and rural environments were first reported from Germany in 1965, followed by many reports of higher rates of asthma symptoms in urban than rural environments around the world including Africa, Asia and Papua New Guinea. Authors have suggested that wealth, lifestyle, housing and urban environmental exposures may contribute to increasing asthma prevalence. In relati...
Urbanisation is one of the most dramatic forms of land use change which relatively few species can adapt to. Determining how and why species respond differently to urban habitats is important in predicting future biodiversity loss as urban areas rapidly expand. Understanding how morphological or behavioural traits can influence species adaptability to the built environment may enable us to impr...
Urbanisation of natural habitats is rapidly intensifying and poses a potential global threat for wildlife. Thus, it is important to explore its impact on wildlife in order to understand the present and future threats and how resilient organisms are to them. Although many species decline in abundance or even disappear once an area is urbanised, some species, populations and/or individuals are ab...
Almost two and a half billion people representing 45 per cent of the world's population live in urban areas. In 1990,37 per cent of the developing world's population lived in urban areas and about one third of the urban population in the developing countries lived in urban slums and shanty towns. In 1990, more than 75 per cent of all South Americans were living in urban areas, the highest degre...
BACKGROUND Social and environmental changes have accompanied the ongoing rapid urbanisation in a number of countries during recent decades. Understanding of its role in the health-risk transition is important for health policy development at national and local level. Thailand is one country facing many of the health challenges of urbanisation. OBJECTIVE To identify potential associations betw...
Urbanisation currently threatens over one-third of the world’s known amphibian species. The main threats of urbanisation to amphibian populations are habitat loss, habitat fragmentation and isolation, and degradation of habitat quality. A complex array of interacting biotic and abiotic factors impact amphibians in urban and urbanising landscapes. These can lead to a decrease in species richness...
