1 WORLD AGRICULTURE TOWARDS 2030/2050 The 2012 Revision Nikos Alexandratos and Jelle Bruinsma Global Perspective Studies Team ESA Working Paper No. 12-03 June 2012 Agricultural Development Economics Division Food and AGRICULTURE Organization of the United Nations i WORLD AGRICULTURE TOWARDS 2030/2050 : the 2012 revision Nikos Alexandratos and Jelle Bruinsma Global Perspective Studies Team FAO Agricultural Development Economics Division Abstract This paper is a re-make of Chapters 1-3 of the Interim Report WORLD AGRICULTURE : TOWARDS 2030/2050 (FAO, 2006).

2 In addition, this new paper includes a Chapter 4 on production factors (land, water, yields, fertilizers). Revised and more recent data have been used as basis for the new projections, as follows: (a) updated historical data from the Food Balance Sheets 1961-2007 as of June 2010; (b) undernourishment estimates from The State of Food Insecurity in the WORLD 2010 (SOFI) and related new parameters (CVs, minimum daily energy requirements) are used in the projections; (c) new population data and projections from the UN WORLD Population Prospects - Revision of 2008; (d) new GDP data and projections from the WORLD Bank.

3 (e) a new base year of 2005/2007 (the previous edition used the base year 1999/2001); (f) updated estimates of land resources from the new evaluation of the Global Agro-ecological Zones (GAEZ) study of FAO and IIASA. Estimates of land under forest and in protected areas from the GAEZ are taken into account and excluded from the estimates of land areas suitable for crop production into which AGRICULTURE could expand in the future; (g) updated estimates of existing irrigation, renewable water resources and potentials for irrigation expansion; and (h) changes in the text as required by the new historical data and projections.

4 Like the interim report, this re-make does not include projections for the Fisheries and Forestry sectors. Calories from fish are, however, included, in the food consumption projections, along with those from other commodities ( spices) not analysed individually. The projections presented reflect the magnitudes and trajectories we estimate the major food and AGRICULTURE variables may assume in the future; they are not meant to reflect how these variables may be required to evolve in the future in order to achieve some normative objective, ensure food security for all, eliminate undernourishment or reduce it to any given desired level, or avoid food overconsumption leading to obesity and related Non-Communicable Diseases.

5 Keywords: agricultural outlook, food demand, production growth, nutrition, crop production, global outlook, land use, irrigation, crop yields. JEL classification: FO1, O13, Q11, Q17, Q18, Q21, Q24, Q25 ii Acknowledgements This paper was prepared by Nikos Alexandratos (Chapters 1, 2 and 3 and the related quantifications) and Jelle Bruinsma (Chapter 4) who also performed the underlying calculations except for the calculation of water requirements in irrigation which was performed by Jippe Hoogeveen. Comments by Kostas Stamoulis, Dominique van der Mensbrugghe, Piero Conforti, Seth Meyer and the provision of data and projections by the team that prepared the OECD-FAO Agricultural Outlook are gratefully acknowledged, as are comments on Chapter 4 by G nther Fischer, Harrij van Velthuizen and Freddy Nachtergaele (on GAEZ), Jean-Marc Faur s, Jacob Burke and Jippe Hoogeveen (on irrigation), Simon Mack (on livestock) and Jan Poulisse (on fertilizers).
