The goal of this backgrounder is to provide an initial review of the literature with respect to food security as it relates to climate change in the Rossland, Castlegar and Kaslo regions. It is intended to outline what we currently know with regard to food security, identify questions that require further research and provide a basis for each of the three Phase II communities undertaking the Columbia Basin Trust’s Communities Adapting to Climate Change to complete local or regional vulnerability assessments with regard to food security.
