Due to the convenient transportation and construction, cities are prone to be situated in areas with flat terrain and unstable sediments, resulting in the concurrence of ground subsidence and urbanization. Here the interaction between geology, anthropogenic processes and ground subsidence geo-hazards were investigated in the Greater Pearl River Delta region of China. Geological evidences and 20...

This paper assesses the relationship among energy consumption, financial development, economic growth, industrialization and urbanization in Tunisia from 1971 to 2008. The autoregressive distributed lag bounds testing approach to cointegration and Granger causality tests is employed for the analysis. The result confirms the existence of long-run relationship among energy consumption, economic g...

Using a process-based Dynamic Land Ecosystem Model, we assessed carbon dynamics of urbanized/developed lands in the Southern United States during 1945-2007. The results indicated that approximately 1.72 (1.69-1.77) Pg (1P = 10(15)) carbon was stored in urban/developed lands, comparable to the storage of shrubland or cropland in the region. Urbanization resulted in a release of 0.21 Pg carbon to...

This paper exploits the significant positive response of the share of agricultural value added and GDP per capita growth to variations in the international prices for agricultural commodities and rainfall to construct instrumental variables estimates of the causal effect that changes in the size of the agricultural sector and GDP per capita growth have on the urbanization rate for a panel of 41...

Cities are at the centre of Asia-Pacific’s economic growth and development. They provide the environment and social milieu in which more and more people live. Urban areas in the region, though containing around 42 percent of its population, account for 80 percent of the region’s GDP1. Urbanization in Asia and the Pacific is proceeding at a scale and speed unprecedented in human history. It took...

Urban dwellers are rapidly becoming a majority of the population. Most of them live in developing countries, and an ever-higher proportion in the biggest cities. Most of the world’s largest cities are now in developing countries, and they are growing to sizes never before experienced. The urban population is growing several times as fast as in the rural areas, either through natural growth (the...

Adapting virtualization concepts to satisfy network telecommunication challenges receives more and more attention. The virtual network environment is formed by the amount of bounded virtual resources provided by physical network equipments. Deploying virtual network infrastructure has recently caught more research interests due to its flexibility and manageability. However, virtual network depl...

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...
