Smallholder commercialisation is constrained by systemic risks. Business models to reduce these risks focus on correcting market failures but pay less attention to risks from natural shocks. The SRMS project developed a replicable business model (RBM) to reduce market risks for the commercialisation of teff in South Wollo Zone, Amhara region, Ethiopia. To test the robustness of this RBM to natural shocks, SRMS designed a risk simulation game to capture the impact of variable rainfall on teff production and commercialisation. This report details the findings of the risk simulation game.
