Agricultural innovation and adaptation to climate change: Insights from US maize

Abstract Climate change is a major threat to the global food supply, and adaptation by technological progress essential. We show that scope of required innovation challenging. Our benchmark estimated yield gain in US maize due genetically engineered (GE) varieties. Extrapolated future yields, given climate projections, indicate significant negative impacts change. Yield shortfalls, end century, range from 2.8 6.3 times total gains first‐generation GE Ambitious targeted R&D efforts, breakthroughs, may be offset impact
