(Reuters) - The ravages from half a century of intensive farming must give way to a more sustainable approach if farmers are to feed the world in 2050, the United Nations' Food and Agriculture Organization (FAO) said on Monday.
Global farm output must increase 70 percent, including a nearly 100 percent jump in developing countries, to feed the world in 2050, the FAO said.
At the same time, farmers must conserve resources and protect environment, said the FAO, which expects the world's population to rise to about 9.2 billion in 2050 from 6.9 billion in 2010.
Climate change and growing competition for land, water and energy with industries mean agriculture can no longer rely only on intensive crop production.
