Different models of cities around the world: Smart cities
<![CDATA[It is estimated that the planet will be home to almost 10 billion people by 2050 and about 70 percent will live in urban areas. Furthermore, cities not only account for up to 80 percent of energy consumption, but they also make a decisive contribution to global warming. The challenges that cities face today - and in the future - have to do with large traffic jams, landfills that do not give more of themselves, housing problems (shortages and high prices), inequality and inefficient public transport, among other problems. That is why urban areas around the world are developing a host of innovative solutions to make the urban areas of the future healthier, safer, more inclusive and smarter. Cities are increasingly turning to digital data and technologies to improve the quality of life of their citizens and create a healthy environment in which the challenges of everyday life are minimized. Solutions range from greener spaces and better access to arts and culture, to underground recycling systems and car-free zones. But this also includes safer streets, the development of urban farms and forest buildings, the implementation of efficient public transportation, and anything in between imaginable.
