The OECD-FAO Agricultural Outlook 2020-2029 is a collaborative effort of the Organisation for Economic Co-operation Development (OECD) and the Food and Agriculture Organization (FAO) of the United Nations, incorporating expertise from collaborating member countries and international commodity organisations. It provides market projections for national, regional and global supply and demand of major agricultural commodities, biofuel and fish. During the preparation of the OECD-FAO Agricultural Outlook 2020-2029, the exact effects of the COVID-19 pandemic on agricultural markets were still largely unknown and they were therefore not incorporated in the baseline projections. Nevertheless, the Outlook aims to outline the channels of transmission of COVID-19 impacts on the various food and agriculture sectors. Supplementary information can be found at www.agri-outlook.org.
