Most of the expansion is projected in the RoW group, in particular Sub-Saharan Africa. After peaking (before 2030), global food crop area is projected to decline, particularly in North America, Brazil, Russia, South Asia and China. This is based on the assumptions of slowly growing populations in the OECD and a shrinking population in Russia and China, stabilising diets (i.e. maximum caloric intake being reached) in most OECD and BRIICS countries, and increasing crop yields due to technological improvements (for a further discussion of the agricultural land projections under the Baseline scenario, see Chapter 2).
