Asia helps Africa in a sugarcane field on Taiwan. Seeking ways to improve their sugar industry, trainees from Liberia take lessons from an island that has become a classic example of agricultural efficiency. In rich and poor countries alike, scientists are accelerating the pace of agricultural research, focusing on the needs of the tropical hunger belt. A similar massive effort launched the Green Revolution of high yielding wheat and rice varieties in the 1950's and 1960's. Beneath a canopy of monsoon clouds (right), villagers in Thailand transplant seedlings of the "miracle" rice that helps make their nation a grain exporter. But the worldwide shortage of fertilizer-upon which new varieties depend-has dealt a severe blow to the Green Revolution.
