Living in green/blue areas is associated with better health. This may be due to low air and/or noise pollution, opportunities for physical activity, facilitation of social contacts, and promotion of recovery from fatigue and stress. Yet, socio-economic (SE) factors also explain inequalities in health and access to green/blue spaces. The GRESP-HEALTH project evaluates the associations between li...

There is mounting evidence that urban areas influence biodiversity. Generalizations however require that multiple urban areas on multiple continents be examined. Here we evaluated the role of urban areas on avian diversity for a South American city, allowing us to examine the effects of urban features common worldwide, using the city of Valdivia, Chile as case study. We assessed the number of b...

plants as the life giving entities have important role in mental and physical health of human. in the modern time with expansion of the cities and increase  of industrial centers and living style change and decrease of social negligence about green spaces as the factor for mental diseases, altogether have been propounded for many psychologists and physicians. in this way considering green space...

historic urban areas are a significant part of each city not only due to having irreplaceable cultural and social resources, but also due to their attractive patterns of life. they have being threatened by strong development trends. this paper aims to investigate the impacts of redevelopment trends in the historic city of shiraz, iran. the paper begins by highlighting historical development in ...

Connectivity is a vital element in landscape structure because of its importance in species–landscape interactions. Connectivity analysis of green spaces in urban landscapes, especially in high-density cities such as Hong Kong, differs from that of habitats in natural or rural landscapes. Using the human being as the target species, we formulated with GIS techniques a resistance weight, a struc...

The urban environment is characterized by an intense use of the available space, where the preservation of open green spaces is of special ecological importance. Because of dynamic urban development and high mapping costs, municipal authorities are interested in effective methods for mapping urban surface cover types that can be used for evaluating ecological conditions in urban structures and ...

Urban land area in the United States is projected to increase to 8.1% of total land area by the year 2050. These human-dominated environments create conditions that degrade both terrestrial and aquatic ecosystems. If cities are to reduce their environmental impact, innovative practices must be developed that replace ecosystem services lost during the urbanization process. This study evaluated t...

urban expansion model (uem) was adapted to simulate urbanization which implements geospatial information systems (gis), artificial neural networks (anns) and remote sensing (rs). two satellite imageries with specific time interval, socio-economic and environmental variables have been employed in order to simulate urban expansion. socio-economic and environmental variables were used as inputs wh...

in this study which was carried out in 1974 in the province of isphahan a total of 23,273 individuals in the cities, and 18,671 individuals in the villages of the same area were studied. results show that the median age in rural area is 16 and in urban area is 18 years. the birth rate in rural is 27.7 per thousand were as the same rate in urban area is 40.2 per thousand. similarly the general f...
