<P> The Green Revolution was a series of research, development, and technology transfer initiatives, between the 1940s and the late 1970s . It increased agriculture production around the world, especially from the late 1960s . The initiatives, led by Norman Borlaug and credited with saving over a billion people from starvation, involved the development of high - yielding varieties of cereal grains, expansion of irrigation infrastructure, modernization of management techniques, distribution of hybridized seeds, synthetic fertilizers, and pesticides to farmers . </P> <P> Synthetic nitrogen, along with mined rock phosphate, pesticides and mechanization, have greatly increased crop yields in the early 20th century . Increased supply of grains has led to cheaper livestock as well . Further, global yield increases were experienced later in the 20th century when high - yield varieties of common staple grains such as rice, wheat, and corn were introduced as a part of the Green Revolution . The Green Revolution exported the technologies (including pesticides and synthetic nitrogen) of the developed world to the developing world . Thomas Malthus famously predicted that the Earth would not be able to support its growing population, but technologies such as the Green Revolution have allowed the world to produce a surplus of food . </P> <P> Although the Green Revolution significantly increased rice yields in Asia, yield increases have not occurred in the past 15--20 years . The genetic "yield potential" has increased for wheat, but the yield potential for rice has not increased since 1966, and the yield potential for maize has "barely increased in 35 years". It takes only a decade or two for herbicide - resistant weeds to emerge, and insects become resistant to insecticides within about a decade, delayed somewhat by crop rotation . </P> <P> For most of its history, agriculture has been organic, without synthetic fertilisers or pesticides, and without GMOs . With the advent of chemical agriculture, Rudolf Steiner called for farming without synthetic pesticides, and his Agriculture Course of 1924 laid the foundation for biodynamic agriculture . Lord Northbourne developed these ideas and presented his manifesto of organic farming in 1940 . This became a worldwide movement, and organic farming is now practiced in most countries . </P>

When did humans first introduce the farming package
