As a vital indicator for measuring urban development, urban areas are expected to be identified explicitly and conveniently with widely available dataset thereby benefiting the planning decisions and relevant urban studies. Existing approaches to identify urban areas normally based on midresolution sensing dataset, socioeconomic information (e.g. population density) generally associate with low...

Domestic cats (Felis catus) are the most abundant predator in many urban ecosystems, and their ranging behaviour will influence predation rates. To investigate how degree of urbanisation affects cat ranging behaviour, we used Global Positioning System trackers to follow 38 cats in 3 (urban, suburban and peri-urban) residential areas in the large town of Reading, UK. Median home range (95% KE) w...

Using aerial photograph interpretation of circa 2005 imagery, percent tree canopy and impervious surface cover in the conterminous United States are estimated at 34.2% (standard error (SE) = 0.2%) and 2.4% (SE = 0.1%), respectively. Within urban/community areas, percent tree cover (35.1%, SE = 0.4%) is similar to the national value, but percent impervious cover is significantly higher (17.5%, S...

Surface urban heat island (SUHI) is defined as the elevated land surface temperature (LST) in urban area in comparison with non-urban areas, and it can influence the energy consumption, comfort and health of urban residents. In this study, the existence of daytime SUHI, in Cairo and its new towns during the summer, is investigated using three different approaches; (1) utilization of pre-urbaniz...

During the last 100 years in many countries of the world, there have been dramatic changes in natural/rural landscapes due to urbanization. Since many wildlife species are unable to adapt to these alterations in their environment, urbanization is commonly responsible for a decline of biodiversity in areas of urban development. In contrast, some wild animal species are attracted to peri-urban an...

This article wants to propose this theory that Farm Corporations are agropolitan development models in Iran. As over-concentrating investments to the urban areas did not lead to a trickledown effect to the rural areas. To the extreme, there are ideas to minimize linkages with the urban economy, and to make the rural areas pursue self-sufficiency by maximizing its potentials. However, against th...
