Tightening the Belt: A Comparative Analysis of the Effectiveness of the Urban Growth Boundary in Portland, Oregon and the Ontario Greenbelt in the Greater Toronto Area, Ontario
MetadataShow full item record
As the world’s population continues to increase, development is inevitable. Within North America, this has led to continuing sprawl and expansion of cities, which is resulting in a catastrophic loss of farmland. This is referred to as urban sprawl. Policy has been implemented as a means of combatting urban sprawl, and through the examination of two key greenbelt policies within North America – the Ontario greenbelt in Ontario, Canada and the Urban Growth Boundary in Portland, Oregon – this study aims to examine which is more effective. This study will look at five key variables as a means of analyzing both greenbelt policies and their effectiveness since their implementation. This study will suggest that both the Ontario and Portland greenbelt policies have been moderately effective in controlling urban sprawl, but will also pin point which has been more effective and why. The conclusions of this study are important to future policy implementation and policy review. Further studies should be done to compare other variables, and an addition quantitative analysis would be able to provide statistical comparisons of the two cases chosen.
