Futures studies’ backcasting method used for strategic sustainable city planning

Achieving a sustainable city requires long-term visions, integration and a system-oriented approach to addressing economic, environmental and social issues. This paper case studies a sustainable city planning project, Göteborg 2050, that uses the backcasting method. Visionary images of a long-term sustainable future can stimulate an accelerated movement towards sustainability. The paper describes a special kind of scenario methodology to build a future model for city development as a planning tool in facilitating a sustainable society. Backcasting in futures studies is widely discussed together with the comparison of three selected backcasting approaches, including Robinson's approach, The Natural Step Framework, and the Sustainable Technology Development approach. The purposes of this paper are to examine and discuss the use of the backcasting method within the Project Göteborg 2050, lessons learned and findings drawn from the experience. The case study shows that backcasting is an appropriate method in developing action plans for achieving urban sustainability. This work can be served as a model for sustainable city planning in Thailand as well as other countries.
