Today, half of the world’s population lives in urban areas. By 2050, 70 percent of the population will be urban. India has been witnessing massive urbanization. Over the six decades since independence, India’s population grew three-fold from 350 million in 1947 to 1027 million in the year in 2001. During the same period, the urban population grew almost 4.6 fold as fast – from 62.4 million to 2...
BACKGROUND Epidemiological studies over the last decade have supplied growing evidence of an association between urbanization and the prevalence of psychiatric disorders. Our aim was to examine the link between levels of urbanization and 12-month prevalence rates of psychiatric disorders in a nationwide German population study, controlling for other known risk factors such as gender, social cla...
Responses of benthic macroinvertebrates along gradients of urban intensity were investigated in nine metropolitan areas across the United States. Invertebrate assemblages in metropolitan areas where forests or shrublands were being converted to urban land were strongly related to urban intensity. In metropolitan areas where agriculture and grazing lands were being converted to urban land, inver...
Urbanization in China has in part been subject to centrally planned control and in part has resulted from the pressures of industrialization and economic development. One of the major, if neglected, influences has been the social policies controlling internal migration and influencing urban-rural inequalities in income and social welfare. Urbanization poses continuing and growing challenges for...
The interactions between urbanization with biodiversity and ecosystem services that take place defy simple generalizations. There is increasing evidence for the negative impacts of urbanization on biodiversity, most directly in the form of habitat loss and fragmentation. Recent forecasts suggest that the amount of urban land near protected areas is expected to increase, on average, by more than...
In this paper we determine the main driving forces underlying the structural transformation and urbanization process in rapidly industrializing countries. We use a dynamic, small open economy model with an abundant supply of surplus labor in rural areas, two types of traded goods manufactured in urban areas, and barriers to both trade and migration. The model is supplemented with quantitative a...
Urbanization is intensifying worldwide, with two-thirds of the human population expected to reside in cities within 30 years. The role of cities in human infectious disease is well established, but less is known about how urban landscapes influence wildlife-pathogen interactions. Here, we draw on recent advances in wildlife epidemiology to consider how environmental changes linked with urbaniza...
INTRODUCTION Socioeconomic inequalities affecting health are of major importance in Europe. The literature enhances the role of social determinants of health, such as socioeconomic characteristics and urbanization, to achieve health equity. Yet, there is still much to know, mainly concerning the association between cause-specific mortality and several social determinants, especially in metropol...
We explored the process of urbanization in a mountainous area to seek a sustainable urbanization strategy. Previous urbanization research has mainly focused on flat terrain and coastal areas, and urbanization in mountainous areas remains poorly understood. This study integrated geographic information systems, remote sensing, and statistical analysis to quantify landscape patterns dynamics in re...
How urbanization shapes population genomic diversity and evolution of urban wildlife is largely unexplored. We investigated the impact of urbanization on white-footed mice,Peromyscus leucopus,in the New York City (NYC) metropolitan area using coalescent-based simulations to infer demographic history from the site-frequency spectrum. We assigned individuals to evolutionary clusters and then infe...
