This book brings together a collection of papers prepared for the Global Forum on Agriculture that took place at the OECD in December 2014. It reviews current knowledge about agricultural policy and agricultural trade policy settings, and questions its pertinence in light of the profound market and structural changes that have been taking place in the global agro-food sector in recent decades. It aims to inform and assist policy-makers and negotiators as they seek to overcome the problems that have made the agricultural pillar of the Doha Agenda trade negotiations particularly difficult. The data and analysis presented cover OECD countries and major G20 and emerging economies that account for the great bulk of global food production, consumption and trade.
