Climate change is likely to undermine food production in the developing world, while industrialized countries could gain in production potential, FAO Director-General Jacques Diouf said today in a speech at the M.S. Swaminathan Foundation Conference in Chennai, India. [...] But, he cautioned, most genetically modified (GM) crops being cultivated today were developed to be herbicide tolerant and resistant to pests. Development of GM crops with traits valuable for poor farmers, especially within the context of climate change -- such as resistance to drought, extreme temperatures, soil acidity and salinity -- is not yet a reality.
