Food shortages could be most critical world issue by mid-century

The world is less than 40 years away from a food shortage that will have serious implications for people and governments, according to a top scientist at the U.S. Agency for International Development. "For the first time in human history, food production will be limited on a global scale by the availability of land, water and energy," said Dr. Fred Davies, senior science advisor for the agency's bureau of food security. "Food issues could become as politically destabilizing by 2050 as energy issues are today." Davies, who also is a Texas A&M AgriLife Regents Professor of Horticultural Sciences, addressed the North American Agricultural Journalists meeting in Washington, D.C. on the "monumental challenge of feeding the world."
