Cereal demand would be reduced by as much as 6 percent in developing countries compared with scenario 1 because people could not afford to buy as much at the higher prices. Scenario 3 compounds the slower yield growth with a 20 percent decline in the growth of national incomes in developing countries. The results clearly indicate that it is critical to maintain yield growth rates in developing economies, particularly in Sub- Saharan Africa. Because lower food production is associated with income losses, it would be disastrous in developing regions. Higher prices would also have a profound impact on effective demand and the ability of the world's poor to obtain adequate food supplies.
