Abstract espite doubling of yields of major grain crops since the 1950s, more than one in seven people suffer from malnutrition ( 1). Global population is growing; demand for food, especially meat, is increasing; much land most suitable for annual crops is already in use; and produc-tion of nonfood goods (e.g., biofuels) increas-ingly competes with food production for land ( 2). The best lands have soils at low or mod-erate risk of degradation under annual grain production but make up only 12.6 % of global land area (16.5 million km2) ( 3). Supporting more than 50 % of world population is another 43.7 million km2 of marginal lands (33.5 % of
