As global urbanization continues, resources will begin to run low. Health care will not be able to keep up. Energy demands will exceed current capacity. Where will everyone work? How can governments and policy makers facilitate an environment conducive to economic growth? Cities around the world are working to become what we call "smart cities", an environment for addressing the challenges of advanced urban planning, energy and transportation management and urbanization by combining new technology. They’re using IoT connected devices to do everything from detecting gunshots to monitoring traffic and air quality. According to a report by McKinsey, by 2020 the number of smart cities will be about 600 worldwide, and 5 years later almost 60 percent of the world’s GDP will be generated by them.
