The Global Agricultural Productivity Gap, 2010-2050. Feeding the world by 2050 will require increasing agricultural output by 70 percent.16 To achieve this, agricultural productivity will need to grow at an annual average rate of at least 1.75 percent from a relatively fixed bundle of agricultural resources given growing regional scarcities of water and arable land. As noted earlier, over the past seven years, that rate has averaged 1.4 percent. DuPont, 2011
