The spatial deconcentration of population during the 20th century and the resulting expansion of human settlements has been a significant cause of anthropogenic landscape change in the United States and many other countries. In the seven-state North Central Region, as in other regions of the US, changing human settlement patterns are most prominent at the outlying fringe of metropolitan areas a...

  There is a significant relationship between economic growth and the degree of urban concentration, as measured by primacy or the share of the largest city in an urban system. In accordance to urban economic theories, there is an inverse-U shape relationship between urban concentration –urban primacy- and economic growth. That is, as economy grows, urban concentration increases, approaches a...

Urban trees are a dominant natural element in cities; they provide important ecosystem services to urban citizens and help urban areas adapt to climate change. Many rationales have been proposed to provide a purpose for urban forest management, some of which have been ineffective in addressing important ecological and social management themes. Among these rationales we find a values-based persp...

Firearms hunting often is limited as a deer (Odocoileus spp.) management tool in urban and suburban areas due to firearms discharge ordinances, restrictive hunting laws, or public perception about firearms safety. Many states use bowhunters to manage overabundant deer populations in urban–suburban areas. Little information exists on the effectiveness of bowhunting as a deer management tool in d...

urban settlements and their connectivity will be the dominant driver of global change during the twenty-first century. in an attempt to assess the effects of urban growth on available land for other uses and its associated impacts on environmental parameters, we modeled the change in the extent of gorgan city, the capital of the golestan province of iran. we used landsat tm and etm+ imagery of ...

Land use changes result from population growth and migration of poor rural people to urban areas for economic opportunities. Changes in land use directly influence the regional air quality, energy consumption and climate at global, regional and local scales. Controlled, coordinated and planned urbanization is a gift to the human society. However, unplanned urbanization can be a disaster. Urban ...

Urbanization is one of the great challenges of our time and unchecked haphazard urbanization is a serious threat both to the environment and social and economic balance. In order to meet global sustainability targets, rapid urban growth must be channelled into environmentally friendly, sustainable and liveable urban environments. Thus, this special issue focuses on sustainable urban design whic...

the shape of urban development and its impact on economic growth is one of the most important issues in urban economic literature. in accordance to the corresponding theory, economic growth and urban concentration have an inverse-u shape relation. the shape of urban development is related to how resources are spread out in existing cities of an urban system and investigated under the term of ur...
