The Regional Centre of Expertise on Education for Sustainable Development in Saskatchewan (RCE Saskatchewan, Canada) is part of the United Nations University RCE Initiative in support of the UN Decade of Education for Sustainable Development (2005-14). With funding from the Government of Saskatchewan's Go Green Fund, RCE Saskatchewan carried out research identifying education for sustainable development (ESD) projects within six priority areas for sustainability in its Canadian prairie region. This ESD capacity assessment was conducted by eight post-secondary students from late 2007 to 2009 and resulted in a searchable database and visual representation (map) of these ESD projects along with ongoing documentation of project milestones and processes. The database has become a useful tool assisting networking of Saskatchewan ESD providers, researchers and participants. This article describes the importance of the inventory in advancing the RCE, the project conception and management, the processes utilised for its successful completion (including descriptions of the technology utilised), the project findings and their implications. It concludes that for an RCE with minimal resources, an ESD project inventory employing student researchers within a higher education setting using Free/Open Source technologies is a cost-effective way of advancing the networking and capacity-building goals of an RCE.
