Climate change has already altered global patterns of biodiversity by modifying the geographic distributions of species. Forecasts based on bioclimatic envelop modeling of distributions of species suggests greater impacts can be expected in the future, but such projections are contingent on assumptions regarding future climate and migration rates of species. Here, we present a first assessment ...

Educational tourism, a burgeoning section in China’s tourism market, has attracted great attention from both industry and researchers, however, the focus always falls on young people, the educational demands of other tourists are largely neglected. The paper, firstly does a comprehensive analysis of situation and problems of Chinese inbound, outbound and domestic education tourism markets, and ...

Traffic and census tract population projections are analyzed using ArcGIS to estimate future potable water demands for the City of Tucson, Arizona. The estimated demands are applied to Tucson Water’s current hydraulic model using Haestad Methods’ WaterGEMS software. The model is then used to determine what facility and piping modifications will be required to meet growth within current service ...

this study aims to investigate the effective factors on non-development of tourism industry in golestan province. the standard questionnaires are used to doing this descriptive, cross-sectional and tentative that those be scattered after measuring their validity and reliability based on simple-random sampling(for tourists) and taxonomy-sampling(for experts) between tourists and experts. the ana...

remote sensing techniques are known as very useful methods for studying land use management in arid and semi arid areas, where undeveloped soils are dominant. these techniques can be used for determining different environmental characteristics including soil and vegetations. in this study etm+ band ratios and principal component analysis (pca) were used for monitoring of vegetation cover and it...

Global warming is expected to increase the frequency and intensity of droughts in the twenty-first century, but the relative contributions from changes in moisture supply (precipitation) versus evaporative demand (potential evapotranspiration; PET) have not been comprehensively assessed. Using output from a suite of general circulation model (GCM) simulations from phase 5 of the Coupled Model I...
