The Illinois Geographic Information System was used to compare the soil and landscape attributes of the State with its historic vegetation, current land use, and patterns of land-use change over the past 160 years. Patch structural characteristics among land types in four geographic zones were also compared. The assessment of patch characteristics revealed a highly modified State with most land...

IN TR O D U CTIO N For decades the highway location team has based consideration of alternatives on such basic factors as right-of-way and construction costs, length of alternative routes, number of structures required, number of homes displaced, benefit cost ratios and other traditional considera­ tions. This approach, originally applied to rural projects, gradually crept into use in urban hig...

The majority of the world's population will live in cities in the next few years, and the pace of urbanization worldwide will continue to accelerate over the coming decades. Such a dramatic demographic shift can be expected to have an impact on population health. Although there has been historic interest in how city living is associated with health, this interest has waxed and waned and a cogen...

While Canada ranks second in the world in terms of national land area, its most productive arable land is limited in extent. These lands are also under pressure due to rapid urbanization, especially in the high growth areas of southern Ontario, the CalgaryEdmonton corridor and the lower Fraser River valley of British Columbia. Currently, a program is underway in the Earth Sciences Sector of Nat...

The conversion of natural habitat to urban settlements is a primary driver of biodiversity loss, and species' persistence is threatened by the extent, location, and spatial pattern of development. Urban growth models are widely used to anticipate future development and to inform conservation management, but the source of spatial input to these models may contribute to uncertainty in their predi...

During the past decade, archaeological studies conducted in the Seymareh River catchment area have provided invaluable findings for analytical investigations and, thus, gaining insights into various fields such as pottery, architecture, and multifarious cultural artefacts. Amongst the most significant of such archaeological findings are cemeteries with their cultural implications, which provide...

A preliminary 1:24,000 scale surficial geologic map of the Detroit 7.5 minute topographic quadrangle, and surrounding areas, was produced to serve as a framework for future urban site assessment. The results show that the map area is a relict late Pleistocene glacial landscape on which is superimposed a Holocene system of streams, lakes and wetlands, and an Anthropocene landscape of manufacture...
