The State of Agricultural Commodity Markets 2020 (SOCO 2020) aims to discuss policies and mechanisms that promote sustainable outcomes – economic, social and environmental – in agricultural and food markets, both global and domestic. The analysis is organized along the trends and challenges that lie at the heart of global discussions on trade and development. These include the evolution of trade and markets; the emergence of global value chains in food and agriculture; the extent to which smallholder farmers in developing countries participate in value chains and markets; and the transformative impacts of digital technology on markets. Along these themes, SOCO 2020 discusses policies and institutions that can promote inclusive economic growth and also harness markets to contribute towards the realization of the 2030 Agenda and its Sustainable Development Goals.
