In Canada and globally, there is growing use of natural infrastructure (NI)—actively managed natural systems and resources such as plants, soil and wetlands—to address increasing risks related to climate change and to meet pressing environmental and economic needs. The Advancing Natural Infrastructure in Canada forum, convened by the International Institute for Sustainable Development (IISD) and partners on 14 November 2018, in Winnipeg, Canada, brought together experts in related fields from across the country to discuss how Canada can use NI to build more resilient cities, towns and landscapes in the face of increasing climate uncertainty. This report presents key insights and next steps from the forum on how to improve the implementation of NI across Canada, including the need for dedicated funding programs, outcome evaluation and performance metrics, guidance and capacity building for planning and implementation, and communication.
