Governments have traditionally equated economic progress with steel mills and cement factories. While urban centres thrive and city dwellers get rich, hundreds of millions of famers remain mired in poverty. However fears of food shortages, a rethinking of anti-poverty priorities and crushing recession in 2008 are causing a dramatic shift in world economic policy in favour of greater support for agriculture.  last time when the world's farmers felt such love was in the 1970's. At that time, as food prices spiked, there was real concern that the world was facing a crisis in which the planet was simply unable to produce enough grain and meat for an expanding population. Governments across the developing world and international aid organisations plowed investment agriculture in technological breakthroughs, like high-yield strains of important food crops, boosted production. The result was the Green Revolution and food production exploded. into the early 1970s, while But the Green Revolution became a victim of its own success. Food prices plunged by some 60% by the late 1980's from their peak in the mid- 1970's. Policy-makers and aid workers turned their attention to the poor's other pressing needs, such as health care and education. Farming got starved of resources and investment. By 2004's aid directed at agriculture sank to 3.5% and "agriculture lost its glitter", “Also, as consumers in high-growth giants such as China and India became wealthier, they began eating more meat. So grain once used for human consumption got diverted to beef up livestock. By early 2008, panicked buying by importing countries and restrictions slapped on grain exports by some big producers helped drive prices up to heights not seen for three decades. Making matters worse, land and resources got reallocated to product cash crop such as bio fuels and the result was that voluminous reserves of grain evaporated. Protests broke out across the emerging world and fierce food riots toppled governments.
