By 2050, a projected 9.7 billion people will inhabit the planet. How will we produce enough nutritious food to support this burgeoning population and ensure access to food resources, particularly as climate change stresses the environment? This Forum explored innovative methods and systems for producing food, as well as new types of products and underutilized sources. The panelists talked about emerging technologies, including advances in genomics and aeroponics, to grow food. They also discussed ways to sustain at-risk food resources made vulnerable from climate change, and the impacts for populations in developing countries. Part of The Andelot Series on Current Science Controversies, this event was presented jointly with PRI's The World and WGBH on December 13, 2016.
