Agriculture in Asia is intensive even in hilly regions.
Expansion of unutilized land resources provides few opportunities for substantial growth in developing countries today. In areas of Latin America and Africa where additional land does exist, disease, insect,and soil problems prevent its use in agriculture. Abundant labor is available in many countries, and continued growth of the labor force will generate increases in total agricultural output. However, most growth in per-capita agricultural output will have to come from more intensive use of existing resources.
