Mark Lundy presented at the CIAT Annual Program Review on knowledge-driven public-private partnerships. He discussed how CIAT science can add value and promote outcomes at scale through partnerships with the private sector, providing examples such as the uptake of tools and approaches by private sector partners, and using research findings to drive conversations with private sector partners. Potential roles for CIAT in knowledge-driven partnerships include providing scientifically robust evidence and tools for partners to use, embedding research into partner agendas to learn together.
