In the 20th century, big spending in modern and scientific research for agriculture led to the growth of more food in industrial countries. The Rockefeller Foundation and Ford Foundation helped to change these scientific technologies to fit the conditions in developing countries. The first research was on rice and wheat, two of the most important food crops for developing countries. Irrigation and the growth of better plant types, in addition to more use of fertilizers and pesticides, led to more food growth in Asia and Latin America, starting in the late 1960s. The term “Green Revolution” was used to mean the large growth in agriculture that happened at this time.
