Food security and sustainability were among the keywords of the G20 summit and Rio+20 this month. As droughts plagued several regions of the world, many people asked whether the land and ocean will be able to support an estimated 9 billion people in 2050. Writing in the New Scientist, Fred Pearce takes a long look at our prospects in “Peak Planet: Are We Starting to Consume Less?” A new report published by the British Medical Council would seem to belie a trend toward lower consumption. “Weight of Nations” finds that higher levels of obesity could threaten future food security (also see the Weight of Nations Interactive visualization in the Guardian). An analysis in Al Jazeera lends insight into the causes of the decades-long drought and food insecurity in Africa’s Sahel. National Geographic looks at how Uganda’s low-tech farming practices might begin to pay off.
