Population estimation was carried out using high-resolution (20 metres) multispectral satellite data (SPOT) in the Kowloon metropolitan area of Hong Kong, which is characterised by high population density and multipurpose high-rise buildings. The smallest areal unit for census data Tertiary Planning Unit (TPU) -was used to aggregate population. With the aid of a raster GIS (IDRISI) and a vector...

landscape characteristics and land use patterns of watershed demonstrate extension, distribution, density and abundance of human interference. these factors can affect water quality of adjacent aquatic systems within a watershed. land use changes have caused various environmental problems for zayandehroud river,turned it as a sink of pollutant. therefore this is investigated that how would land...

using of different systems of soil plough after changing unconsciously and non-scientific of land use, other soil physical and chemical characteristics affected. this fact, especially in marginal lands and mountainous regions is more visible. this research compared with the purpose of studying land use changing on some soil physical and chemical characters like very tiny sand percent, ph, ec, c...

BACKGROUND Studies examining the health effects of particulate matter <or= 2.5 microm in aerodynamic diameter (PM2.5) commonly use ambient PM2.5 concentrations measured at distal monitoring sites as proxies for personal exposure and assume spatial homogeneity of ambient PM2.5. An alternative proxy-the residential outdoor PM2.5 concentration measured adjacent to participant homes-has few advanta...

Chinese cities are experiencing major environmental e!ects from fossil fuel-based energy consumption for mainly residential and, increasingly, urban transportation uses. Community energy management (CEM) is a sustainable energy strategy which looks at how purposely shaping the built environment and designing urban services in consideration of energy production, distribution and use could a!ect ...

Using data from the 2015 Residential Water Consumption Survey, this study examines residential water-use behavior and attitudes after the recent drought in Fresno, California. Spatial autoregressive models of residential water consumption were estimated, accounting for the effects of social interactions in communities (i.e., neighborhood effects), while controlling for indoor and outdoor house ...
