Rapidly growing Asian economies are expected to account for the greatest share of additional consumption, while saturated levels of per capita food consumption and declining population growth rates result in much slower consumption growth from regions like North America and Europe. Substantial population growth in Africa will drive significant increases in total consumption, however per capita consumption growth in the region remains marginal. Consumption trends also tend toward processed and prepared foods, widening the spread between farm gate and retail prices of food items. Expansion of the livestock sector alters the demand for crops, resulting in a declining share of pure food crops, in favour of crops like coarse grains and oilseeds which are also used to feed livestock.
