Professor Beddington began by giving a brief overview of the report, also entitled The Future of Food and Farming,  stating that the case for urgent action in the global food system is  now compelling, and denying the "foul slander that I've been buying  wheat futures to drive the price up." Although he was able to inject  some levity, it is a deeply serious and somewhat worrying issue. 
Facing  a convergence of threats, the global food system is failing. Each  month, the global population grows by another 6 million, and an  ever-wealthier world means one with more purchasing power, which drives  up prices. Currently, with the global population at 7 billion and  change, more than a billion of those go to bed hungry, and another  billion suffer from malnutrition. And trends suggest that things will  get worse.  
2010 was the first year when more people lived in urban  rather than rural environments; by 2050, we're going to need 30 percent  more food and 40 percent more water than is currently available. 
Beddington's key message was that not acting is not a viable option, and a radical redesign of the global food system is a must.
  As laid out in the report linked above, the system is failing when it  comes to both sustainability and ending hunger. Agriculture consumes  around 70 percent of available water, and that figure rises to more than  80 percent in the developing world. Rivers and aquifers are being  overexploited, including here in the US. Of  11.5 billion hectares (about 28 billion acres) of land being used for  food production, more than 25 percent has undergone human-induced soil  degradation. 
Agriculture is also contributing between 10 and 12  percent of the emissions that drive climate change. And, even with  immediate policy changes, climate change has locked in weather changes  for the next 20 years, which will have an impact on food production.  The 2007-08 food price spike put millions into poverty, and the signs  are there that these food price spikes will continue to happen. Last  year's Russian heat wave halved its harvest, and floods in Pakistan have  been doing its food production no favors either.
Food security in the developing world
IFPRI's  Shenggen Fan discussed the problem of food security in emerging and  developing economies. The lofty Millennium Development Goal of halving  hunger is off-track; it aimed to reduce the number of people in hunger  to 584 million by 2015, but projections suggest that number will be  closer to a billion. Twenty-nine countries, mainly in Africa (but also  in Asia), have alarming or extremely alarming levels of hunger.
