When the human population explosion became evident after World War II, many experts predicted about widespread starvation. Their predictions were based primarily on the assumption that, as in the past, expansion of increase in food production. They ignored possibilities about increase of production on lade already in cultivation; but they were wrong. Scintists and their farmer collaborators developed and put to use intensified soil-watercrop management systems that gave unparalleled increase in food production, especially in Europe and the developing countries of Asia and Latin America. Food production increased moer rapidly than population in all the major regions except Sub-Saharan Africa. Grain harvests nearly tripled worldwide from 1950 to 1990. As a result, the threat of massive starvation was averted, and the cost of foods actually fell. Lowered food prices benefitted the poor people everywhere- in cities as well as in rural areas.
