In Science Channel’s six-part series Ecopolis: City of the Future, Nobel Prize-winning scientist Dr. Daniel Kammen uses the Ecopolis blueprint as a test bed for new technologies that could reshape the environmental circumstances of the future mega-city. Each episode investigates several different visionary, technology-driven solutions to specific future mega-city challenges, such as how to produce enough food and water; find clean and reliable energy sources; reduce our reliance on oil for transportation; discover new ways to manage waste; and, increase the energy efficiency of city buildings. Below a clip from the episode 'Hungry City'.
Today, food travels 1,500 miles on average to reach consumers. By 2050, food will have to travel even farther to cities – amassing more and more carbon emissions – and water will be in short supply. Plus, the meat and dairy industries will continue to put a strain on the environment by producing dangerous methane emissions. In this episode, Dr. Kammen explores the four future-forward technologies of urban farming, methane capture, sound-powered refrigeration and recycling water that could help reduce the risk of a food and water crisis in the cities of tomorrow.
