| Urbanization Component1 #146950 Unless development patterns change, by 2030 humanity’s urban footprint will occupy an additional 1.5 million square kilometres - comparable to the combined territories of France, Germany and Spain—with the equivalent of a city of 1 million needed weekly across the next 38 years. | - UN estimates show human population growing from 7 billion today to 9 billion by 2050, translating into some 1 million more people expected on average each week for the next 38 years, with most of that increase anticipated in urban centres.
