Recent studies suggest that gut microbiomes of urban-industrialized societies are different from those of traditional peoples. Here we examine the relationship between lifeways and gut microbiota through taxonomic and functional potential characterization of faecal samples from hunter-gatherer and traditional agriculturalist communities in Peru and an urban-industrialized community from the US....
This paper aims at developing a multilevel fuzzy decision support model for urban rail transit planning schemes in China under the background that China is presently experiencing an unprecedented construction of urban rail transit. In this study, an appropriate model using multilevel fuzzy comprehensive evaluation method is developed. In the decision process, the followings are considered as th...
On-site sanitation is the main form of excreta disposal in most sub-Saharan African cities and will remain the most appropriate level of service for the urban poor in the medium term. Despite heavy public investment in sewerage systems in most primary and some secondary cities, typically only 10-15% of the urban population benefit from access to the sewer network.

This study analyses the changes in prevalence of undernutrition between the 1980s and 1990s at the national and sub-national levels in India and focuses on the rural-urban comparisons. The study exploits the demographic information available in household surveys to derive a household-specific norm as the calorie cutoff point to measure undernutrition, instead of the single per capita norm used ...
By 2050, half of the net increase in world’s population is expected to reside sub-Saharan Africa (SSA), driving high urbanization rates and drastic land cover changes. However, data-scarce environment SSA limits our understanding urban dynamics region. In this context, Earth Observation (EO) an opportunity gather accurate up-to-date spatial information on extents. During last decade, adoption o...
Remote sensing data were utilized to assess urban land cover and its thermal characteristics through mapping sub-pixel impervious surfaces and assessing thermal infrared images. Landsat imagery was used to calculate variation in urban imperviousness from 1995 to 2002 in the Tampa Bay watershed, Florida. The urban-rural boundary and urban development density were defined by selecting certain imp...
Urban art as an effective and valuable tool has an important role in the qualities of public spaces. The existence of artistic elements in an urban space can be a precondition for the presence or absence of citizens in urban spaces. In this context, the aim of this study was to examine the role of urban and public arts with an emphasis on urban graphics in presence and people-oriented factors o...
Irregular and unstable urban development has increased marginalization, destruction of urban green areas and increased demand for urban land, which in itself has led to the disappearance of urban green spaces and land use change of such lands and is possible. Cause certain global environmental problems such as the formation of urban heat islands, because urban green space is one of the importan...
