Science 2.0 speaks to Fred Davies, senior science adviser for USAID’s Bureau of Food Security, about the threat of global food shortages in the coming years. According to Davies, “Food issues could become as politically destabilizing by 2050 as energy issues are today. … [R]esource limitations will constrain global food systems … [and t]he increases currently projected for crop production from biotechnology, genetics, agronomics, and horticulture will not be sufficient to meet food demand” (4/17).
