This book represents the proceedings of the International Symposium on Agricultural Innovation for Family Farmers: Unlocking the potential of agricultural innovation to achieve the Sustainable Development Goals, which took place at FAO headquarters, 21-23 November 2018. FAO convened the symposium to provide inspiration for innovation actors and decision‑makers to unlock the potential of innovation to drive socio‑economic growth, ensure food and nutrition security, alleviate poverty, improve resilience to changing environments and thereby achieve the Sustainable Development Goals. The proceedings provide a record of the main highlights of the symposium, including the opening plenary session; high-level ministerial segment; innovation fair, with 20 success stories of agricultural innovation; and six highly interactive parallel sessions and two special events dedicated to youth and to chefs and family farmers. It was attended by 540 participants, including 286 delegates from 92 member countries.
