The document summarizes two presentations on partnerships and institutional arrangements for innovation, scaling, and impact. Key points from the first presentation discuss scaling up technology delivery mechanisms to promote livelihood systems. The greatest challenge is scaling systems approaches given various biophysical and socio-cultural factors. The second presentation discusses using innovation platforms as a forum for stakeholders to interact and provide solutions to constraints. CORAF has used this approach to achieve greater impact through improved yields, incomes, and policy changes in multiple countries. Take home messages emphasize the need to optimize whole systems instead of components and match interventions to specific contexts to impact millions of people and hectares.
