The goal of INCrease is to generate, systematize, and transfer knowledge around the production, marketing, and utilisation of INC. The research raises awareness and enhances the potential of INC for sustainable and resilient food systems and gathers concrete economic, environmental, social, and health information on how to improve value chains for INC, how changes in local and national food governance systems can improve INC uptake, and consequently how to improve food and nutrition security and population well-being in disadvantaged communities. This is taking place in transdisciplinary collaboration between four universities (Hohenheim, Western Cape, Zululand, Fort Hare) smallholder cooperatives and value chain and community stakeholders in two provinces (Eastern Cape, KwaZulu-Natal) and through outreach to Southern African partners.
