The breakfast imperative： The changing context of global food security
摘要
The debate on global food security has regained vigor since the food crisis of 2008, when a sudden spike in the prices of staple food commodities dramatically demonstrated that securing the supply and accessibility of food for a world of nine billion people in 2050 cannot be taken for granted(Godfray et al. 2010; Swinnen and Squicciarini 2012; Godfray and Garnett 2014). More importantly, the ensuing debate revealed that views on future production systems and consumption patterns need to be regularly adjusted to accommodate new realities in issues ranging from continuing urbanization to climate change, and to guide policy actions. Here we summarize key trends and relevant policy actions emerging from recent discussions on global food security.
