The world’s population will probably hit 9 billion by 2050. That’s about the only thing agreed upon by partisans in a long-waged debate over how best to feed all those bellies. 

On March 8, Dr. Olivier De Schutter, the United Nations Special Rapporteur on the right to food, released a report arguing that the use of small-scale, diverse farming methods, which he calls “agroecology,” can double agricultural production in poverty-stricken areas, increase the economic prospects of the inhabitants, and improve their local environment. 

This argument refutes a common dismissal of sustainable agriculture: that it could never feed the world. That’s the contention of those who believe in agriculture methods that involve the intensive use of energy, water, machinery, and chemicals to grow cash crop monocultures. I recently discussed these competing paradigms with De Schutter, in the context of what it might look like if industrial agriculture were, in fact, to feed the world. 

“I’m surprised at the simplistic diagnosis that appears to be dominant in public discourse,” De Schutter said. “The official mantra is we need a 70 percent increase in agricultural production to feed the world. But this completely oversimplifies the debate. It only pays attention at the supply side of the equation, when we must also work on demand — for instance the overconsumption of meat in industrialized countries. By 2050, if the current curves continue, 50 percent of global cereal production will go either to feeding cattle or to the irresponsible push towards biofuels production and consumption through fiscal stimuli and subsidies.”
