When was the Green Revolution?

Green revolution - the increase in agricultural production throughout the world since 1945 has been so great it has come to be known as the Green Revolution. World agricultural production in 1964 was one and a half times that of 1948. Much of this increase was due to the redistribution of land and to the grouping of small holdings into larger units. Scientists have contributed new varieties of grass that provide better cover and strength, thus holding the soil in place. Advances have been made in the development of new kinds of plants capable of withstanding drought and maturing fast enough to avoid freezing. Research has led to the discovery of new production methods, fertilizers and pesticides.
