This is the seventeenth edition of the Agricultural Outlook. This report provides world market trends for biofuels, cereals, oilseeds, sugar, meats, dairy products and, for the first time, the fisheries sector over the 2011-20 period. This edition also includes an evaluation of recent developments, key issues and uncertainties in those commodity markets. The projections are the result of close co-operation with national experts in OECD and non-OECD countries. A jointly developed modelling system, based on the OECD's AGLINK and on the FAO's COSIMO models, facilitates consistency in the projections. In the context of the G20 discussions on agriculture, a section of the report is devoted this year to the policy responses to price volatility.
