the goals of sustainable development. The transformation of land and ecological processes resulting from development is a driving force behind the lost ecological services that concern the Millennium Ecosystem Assessment. A quick glance at just a few global trends suggests why urbanization has quickly become an issue in need of deeper understanding. Whereas less than 30 percent of the global po...

The progress of urban remote sensing and GIS in China since the early 1980s is reviewed. The first section introduces the early applications of remote sensing to environmental monitoring and resources investigation, and outlines its achievements. The second section focuses on further analysis of urban expansion from the point of view of spatial distribution patterns and temporal change, taking ...

One-half of the world's population lives in cities and towns; this is expected to increase to 70% by 2050. One in three urban dwellers lives in slums. As the urban population grows, so does the number of urban poor. Out of a billion children living in urban areas, approximately 300 million are suffering from exclusion or are at risk of exclusion. Urban poor children are devoid of basic rights o...

The majority of it will occur in developing nations and create megacities whose populations exceed at least 10 million people. Not all urban areas, however, are growing. Some are actually losing populations b...

In this paper breastfeeding was studied among 10240 urban and 10794 rural mothers, whose children were 18 to 23 months of age. The sample size for rural and urban areas was equal, butin each province the cluster sampling method was used proportional to the population of each district. The results ofthe study show that between 17% to 28% of urban mothers in the provinces have deprived their...
