Useful Knowledge and Building Blocks of Change

How to create more productive, more inclusive, more sustainable and more resilient cities are the central questions facing us today. And these questions are more pressing – much more pressing, in fact – in the cities of less-developed countries, where almost all the growth in the global urban population will take place in the coming decades. For every person added to the cities in more developed countries between now and 2050, 18 will be added to the cities in less-developed ones.

That is why we need practical knowledge on cities and why we need it now. We need pragmatism, a philosophy that evaluates knowledge in terms of its usefulness.
