In 1950, only 86 cities in the world held over one million people. Today there are over 400. By 2020, there will be 600. Although some of this growth will occur within large cities, most will happen within the second-tier cities of developing countries, resulting in the production of fringe settlements at a scale yet unseen. 

The ability to meet the challenges and opportunities presented by this emerging world of rusted metal, blue plastic tarps and broken bits of concrete will be a critical factor in determining the health of our planet.

This is where we work.
