This is the 18th edition of the Agricultural Outlook and the eighth prepared jointly with the Food and Agriculture Organization of the United Nations (FAO). It brings together the commodity, policy and country expertise of both organisations, and input from collaborating member countries. The report provides world market trends for biofuels, cereals, oilseeds, sugar, meats, fish and dairy products over the 2012-2021 period and contains an evaluation of recent developments, and key issues and uncertainties in those commodity markets. A jointly-developed modelling system, based on the OECD’s AGLINK and on the FAO’s COSIMO models, facilitates consistency in the projections. This edition includes a special feature on the challenge of increasing agricultural productivity growth in a sustainable manner.
