The Kenyan Railway Corporation announced on March 21 that it would evict 50,000 people living illegally along its tracks. The plan, which would leave thousands homeless, was temporarily suspended on April 29. There are roughly one billion people living in makeshift communities around the globe, and the number is steadily rising. The United Nations expects that the number of people living in slums and shantytowns will grow by 500 million in each of the next two decades, bringing the total to two billion by 2030. An estimated one-third of all city dwellers live in what are generally known as “informal settlements,” according to the UN Special Rapporteur on Adequate Housing, and Amnesty International counts more than 200,000 world communities that can be defined as slums.
