Low External-Input Technology (LEIT) and Agricultural Development: Robert Tripp
The 1960s was a time of great hope for agriculture in developing countries. It marked the beginning of what became known as the Green Revolution, the principal manifestation of which was the spread of short-strawed, fertilizerresponsive varieties of wheat and rice that led to vast increases in food supplies in many Asian countries. For a while it looked as if the strategy of supplying appropriate varieties and complementary fertilizers, pesticides and other inputs could bring an end to rural poverty and chronic food shortages. The formula was based on provision systems, often subsidized, for external inputs, and relied upon technology packages whose practices were similar to those used in industrialized countries.
