In January, Professor Colette Heald presented a 5-minute slideshow on the environmental impacts on global food security at the 2015 World Economic Forum [WEF] in Davos, Switzerland to an audience of world leaders in business, policy and academia. “In 2050, we are going to have to grow 50 percent more food to feed the planet and environmental pressures are going to make that even harder to achieve,” she said. “The relative impact of air pollution and climate depend on where you are – which one is more important and how this might impact the kind of food you grow.” Other MIT representatives on the panel covered topics including renewable water, sensors to monitor food quality and waste-free cities.
