Agri-food supply chain: evolution and performance with conflicting consumer and societal demands
研究了现代消费者和社会对食品的多维需求（如可持续性、动物福利）如何影响农产品供应链的演变和绩效，并评估了农业政策应对2050年增产70%等挑战的效果。
Modern consumers increasingly demand that their food satisfies multiple ‘quality’ dimensions including those pertaining to its location, sustainability and humane treatment of livestock. Society increasingly demands that, in addition to supplying plentiful and cheap food, agriculture also supply fuel, meet environmental goals and distribute income in an equitable manner. We consider the food chain's evolution and evaluate its performance in meeting these challenges, analyse the impacts of these multidimensional demands on the welfare of the various supply-chain actors, and evaluate agricultural policies in light of the challenges facing modern agricultural markets, including producing at least 70 per cent more food by 2050.
