One impediment to our ability to address major landscape change resulting from climate or demographic changes, or the impacts of disasters such as earthquake, wildfire or drought, is our inability to quickly and effectively learn from each other. The International Geodesign Collaboration was conceived as a means to compare the approaches and experiences of different geodesign teams in tackling the projects they would do normally, but using a common framework of guiding assumptions, project sizes, scenarios, analytical systems and presentation formats. By doing so they enable direct comparison between projects revealing insights into the different priorities and constraints of teams working in contrasting governmental, climatic and demographic settings. Ninety-one participant teams tackled project in thirty-seven countries. This initial summary will be followed by more detailed analysis in the future.
