True orthophoto is a better product than classical in urban areas, because buildings are depicted the correct plane position, and content around building also visible. The main goal of our research was to verify two approaches true production: a) production based on digital terrain model model, b) automatic production. We performed test areas within Municipality Ljubljana. compared both procedu...

The urban heat island (UHI) phenomenon is a harmful environmental problem in urban areas affecting both climatic and ecological processes. This paper aims to highlight and monitor the spatial distribution of Surface UHI (SUHI) in the Casablanca region, Morocco, using remote sensing data. To achieve this goal, a time series of Landsat TM/ETM+/OLI-TIRS images was acquired from 1984 to 2016 and an...

The contribution from different emission sources and atmospheric processes to gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM), particulate bound mercury (PBM) and mercury deposition in eastern China were quantified using the Community Multi-scale Air Quality (CMAQ-Hg) modeling system run with a nested domain. Natural sources (NAT) and six categories of anthropogenic mercury sour...

Urban planning is associated with land transformation from natural areas to modified and developed ones which leads to modification of natural environment. The basic knowledge of relationship between both should be ascertained before proceeding for the development of natural areas. Changes on land surface due to build up pavements, roads and similar land cover, affect surface water flow. There ...

Unreliable electricity supply is a major obstacle to economic development in countries such as India. While electricity problems in the rural areas are widely recognized, scholars have yet to analyze the situation in urban slums. Drawing on 2004-2005 survey data from the India Human Development Survey, we document the electricity situation in slums. We find that while households located in slum...

Urban areas are expanding rapidly, but a few native species have successfully colonized them. The processes underlying such colonization events are poorly understood. Using the blackbird Turdus merula, a former forest specialist that is now one of the most common urban birds in its range, we provide the first assessment of two contrasting urban colonization models. First, that urbanization occu...

Introduction: The results of previous scientific studies made in China and Vietnam have shown a big difference in feeding practices of children living in rural areas and those living in urban areas suggesting the influence of economic and socio-cultural factors. The aim of the study is to compare feeding practices of children under the age of five years between urban and rural areas in southern...

Rapid economic growth in China during the past 25 years has been accompanied by increasing economic inequality. China’s old-age social security system has long been restricted to urban areas, leaving the 70 per cent of the population living in rural areas with little or no coverage. The lack of social security for elderly people in rural areas poses a threat to social stability and raises socia...

BACKGROUND It is generally assumed that urban slum residents have worse health status when compared with other urban populations, but better health status than their rural counterparts. This belief/assumption is often because of their physical proximity and assumed better access to health care services in urban areas. However, a few recent studies have cast doubt on this belief. Whether slum dw...
