Rampant urbanization is a serious threat as the number of people living in cities is likely to double by 2050. Many experts believe six billion people will live in cities by 2050, as compared to the 3.6 billion now and this increase is likely to put enormous pressure on the available resources. Clean water, power, waste management, living space and clean air will be some of the issues facing these future urbanites.
The problems that come with rampant urbanization are also unique opportunities to build cities that are smart and sustainable. Many countries have already embarked on this idea of building such smart citiesand it is estimated that we will be spending a whopping $400 billion a year by 2020 to build them. One of the driving forces behind these smart cities will be technologies such as Big Data and Internet of Things (IoT). In fact, Big Data opens up a world of opportunities for urban planners, government entities and private players to develop a range of applications that will make these future cities more livable.
