Exercise 15

Using the GREENR database, search global population by 2050. (You may need to utilize other related portals to obtain the depth of information necessary to complete your research.) Find three different projections for the global urban population in 2050 and explain how the projections were made. To do this, try to find out the assumptions behind each of the projections with regard to urbanization trends and other factors. Based on your reading, choose the projection that you believe to be the closest to reality and explain why you chose this projection.
