As a result, the average soil quality of land used for agriculture has declined in the Calgary–Edmonton corridor, confirming other studies of the food security implications of urbanization.Īgriculture and Agri-Food Canada (1998) Canada Land Inventory, National Soil DataBase. Urban expansion predominantly occurred on soils that were highly suitable for farming, while new agricultural expansion occurred on soils of poorer quality. Nevertheless, total agricultural land increased in the region because of the greater clearing of natural vegetation for agriculture away from the urban core. We used satellite imagery to develop land cover maps for four different snapshots in time between 19 and used these maps to investigate two principal questions related to urban expansion: (1) How did urban expansion affect other land cover types? and (2) How did urban expansion affect the availability of high-quality agricultural land in the region? Our results show that 60 % of new urban and peri-urban growth between 19 occurred on agricultural land. This study investigated land cover changes that occurred between 19 in the Calgary–Edmonton corridor in Alberta, a region that has undergone considerable recent urban expansion. Rapid urban expansion is a major contributor to environmental change in many parts of the world.
