Measuring and preventing urban sprawl
The "urban sprawl problem" is widely recognised today and is a topic in current
political discussions (Revision of the Regional Land-Use Planning Law, Landscape
Trends in housing development in Switzerland today are clearly in conflict with a sustainable regional planning. A reliable basis for zoning is needed to create legal certainty, to end the competition between municipalities for work opportunities and inhabitants, and to enable a better cooperation on sustainability.
Weighted urban proliferation
A NFP 54 project has managed to develop a method to measure urban sprawl to supplement intuitive assessments of sprawl with the measurable criteria: size of the residential area, dispersion of settlement areas and land use. The effects of each change in the settlement on urban sprawl can then be analysed and deduced in the planning phase, and objectively discussed.
The new formula for weighted urban proliferation provides policy makers and politicians with an instrument for setting future goals and for assessing measures to reduce sprawl.
