There is now a critical mass of empirical evidence to help understand the impacts of market-based sustainability tools on farmer incomes and livelihoods. This webinar is an opportunity to explore this evidence base creatively and analytically through the Evidensia platform (www.evidensia.eco) to support research, policy and practice on living income work. We explore the existing evidence base across sectors, geographies and key topics and tools of interest. It will help develop a common knowledge base on what we know, what we don’t know and where there are critical knowledge gaps in our understanding of impacts on farmer livelihoods. We have the time to review what the evidence base says on key topics and connect this to work in the Living Income Community of Practice (www.living-income.com).
