Agricultural and development economist Christopher B. Barrett, a visiting scholar with the Center on Food Security and the Environment, discusses food systems advances over the past 50 years that have promoted unprecedented reduction globally in poverty and hunger, averted considerable deforestation, and broadly improved lives, livelihoods and environments in much of the world. He shares perspectives on the reasons why, despite those advances, those systems increasingly fail large communities in environmental, health, and increasingly in economic terms and appear ill-suited to cope with inevitable further changes in climate, incomes, and population over the coming 50 years. Barrett explores the new generation of innovations underway that must overcome a host of scientific and socioeconomic obstacles.
