Kampala is the capital of Uganda and also its largest city. Originally made up of hills and wetlands, it was considered an ideal place for hunting. Since the 1960s, the population has grown at an average rate of 5.6 percent a year. As a result, much of the surrounding forests have been lost to the need for charcoal, and area water quality has decreased significantly.
Here, you can see the city in 1974 (left) and 2008. Today, as many as 2.5 million people live in the city — and only 10 percent of those people are thought to have access to the city’s sewer lines.
