Rapidly increasing urbanization in the world, especially in developing countries, let to increasing urban extents. Rapid urban growth causes to appearance many problems such as wasting environmental resources, inability of providing necessary services for citizens and unplanned growth. Urban mangers and planners need tools for understanding amount and size of future urban growths to prevent the...

BACKGROUND The relative shortage of physicians in Japan's rural areas is an important issue in health policy. In the 1970s, the Japanese government began a policy to increase the number of medical students and to achieve a better distribution of physicians. Beginning in 1985, however, admissions to medical school were reduced to prevent a future oversupply of physicians. In 2007, medical school...

A cross the developing world, rural-to-urban migration (i.e. internal as opposed to international migration) is probably the most important demographic phenomenon at this time. In the past year the global population has become 50% urbanized, and Africa is well on the way, and will attain that milestone in two more decades, although with considerable country variation. Asia will attain it five y...

It is generally believed that there is an inverse relationship between population growth and vegetation cover. However, reports about vegetation protection and reforestation around the World have been continuously increasing in recent decades, which seems to indicate that this relationship may not be true. In this paper, we have taken 21 cities in Guangdong Province, China as the study area to ...

Rapid population growth, urbanization, and the growing challenges faced by the urban poor require redefining the paradigm for public health interventions in the 21st century, creating new approaches that take urban determinants of health into consideration. The widening disparity between the urban poor and the urban rich further exacerbates health inequities. Existing tools for global governanc...

The historical demographic analysis in this article is a revision of a paper presented at the Conference of the Northwest Regional Consortium for Southeast Asian Studies in 1988 at the University of Oregon. The author takes the view that fertility has remained high in the Southeast Asian region due to the dynamics of colonialism and the reinforcement of traditional society. Industrialization,...

This paper analyzes the processes and characteristics of urbanization in Shanghai, focusing on the population and land use and land cover (LULC) change, and its correlation with the evolution of climatic and ecological indicators based on the historical land use data, meteorological station data, social statistical data, normalized difference vegetation index (NDVI) and land surface temperature...

Urbanization is the most drastic form of land use change affecting biodiversity and ecosystem functioning and services far beyond the limits of cities. To understand the process of urbanization itself as well as its ecological consequences, it is important to quantify the spatiotemporal patterns of urbanization. Based on historical land use data, we characterize the temporal patterns of Phoenix...

China is undergoing a rapid transformation from a rural, peasant based society into an urban one. This radical change has had a profound effect on the Chinese population due to advancement through job opportunities and new modes of consumption, contributing to a huge spatial shift of population from countryside to city. This effect on China’s urban growth has resulted in a rise in the middle cl...

Recently, new methods have been developed for estimating the current and recent changes in effective population sizes. Based on the methods, the effective population sizes of Korean populations were estimated using data from the Korean Association Resource (KARE) project. The overall changes in the population sizes of the total populations were similar to CHB (Han Chinese in Beijing, China) and...
