Projected population growth by sector

The highest rates of urbanization are in Africa and Asia and by 2030 there will be 53 and 54 percent of their respective populations in urban areas. In Asia many cities will become mega-cities as industrialization proceeds but in Africa the growth of cities is not linked to industrialization and many cities are described as economically marginalized by Cohen (2004). Overall, the use of carbon will become less spatially uniform as its consumption, mainly as food and fuel, increases as cities grow.
