Urbanisation

What will happen with Urbanization?

According to the UN-Report on World Urbanisation Prospect, by 2050, we expect the population to expand from a present 7 billion to 9.5-10 billions. The bulk of the increase, i.e. an additional 3 billions people will go into cities, and not necessarily the mega ones. Consequently, it is also of fundamental importance that we build these new cities, and upgrade the present ones, so that the population will not end up in slums where inclusion, prosperity and health is a constant challenge.

As captured in this introduction video of Science-Magazine, Cities tend to be located in premium locations, also for diversity, tend to absorb more heat, or generate noise and pollution. But they are also places of creativity, and when properly planned, will use less energy per capita. What all this means more precisely is very well captured by the article of the Royal Geographical Society on the Challenges of Urbanisation

Cities of the Future: Getting it right?

This predicted growth of the urbanisation provides a necessity to develop innovative solutions that will address issues such as clean air, safe water, balanced food supply, sustainable mobility, and a circular economy that will both achieve a sound quality of life at an acceptable footprint. The WWF document Urban Solutions for a living planet provides a good introduction to the opportunities, with some examples of solutions.
