The exponential growth of the world’s population will bring with it a considerable increase in the size of major cities. This is inevitable. However, experts claim that this expansion will be more sustainable than we imagine.
Let’s take a look at what might surprise us about the “smart cities” of the future.
In a few decades, more than half of the world’s population will be concentrated in as little as 2% of the planet’s available space. In other words, 2.5 billion people will live in mega cities.
However, contrary to expectations, there will be fewer gridlocks in the city centers. European capitals like Oslo or London have already begun working on this objective by establishing traffic regulations in the city center.
As a result, solutions like WeSmartPark are already essential. An AirB&B style parking system that connects 150,000 users in Madrid, Barcelona, and Santiago de Chile with thousands of available places at half the price. And with an average waiting time that seems unthinkable: only two minutes.
In addition, this rapid growth of cities will also mean having to take on numerous structural and environmental challenges to deal with citizens’ mobility needs.
Governments will increasingly invest in more efficient and sustainable infrastructure, reducing non-recyclable waste and greenhouse gases. Energy savings worldwide are expected to reach 1.7 billion dollars in only a few years.
Quite a feat, isn’t it? Well, companies like Repsol are already working on this: they have developed technology to produce 100% recyclable asphalt for roads. It produces less waste and emissions, and less water is used in the process.
In addition, technological advances will have a greater impact on the development of new construction materials than ever before. From buildings that heal themselves thanks to a “biocement” composed of bacteria to phosphorescent concrete capable of absorbing solar radiation to illuminate the roads of the future.
