The Initial Design document of the Future Earth Urban Platform (FEUP) is complete and available for download. It is a product of the Livable Urban Futures cluster/fast track initiative activity, a partnership between UGEC and the Stockholm Resilience Centre, and funded by Future Earth. The document provides detail on a urban research platform within Future Earth and was co-designed by members of the FEUP core group along with participants at our scoping meeting at The National Centre for Atmospheric Research in Boulder, Colorado this past March.
