Others live in the area because renting homes, largely built of mud and sticks, is relatively inexpensive. Around 500 waste-pickers are believed to work at the landfill every day, sorting through the debris from the capital’s estimated 4 million residents. Addis Ababa Mayor Diriba Kuma said 37 people had been rescued and were receiving medical treatment. The landfill has been a dumping ground for the capital’s garbage for more than 50 years. The dumping had stopped in recent years, but it resumed after farmers in a nearby restive region where a new garbage landfill complex was being built blocked dumping in their area. City officials say close to 300,000 tons of waste are collected each year from the capital. The landslide also buried several makeshift homes and concrete buildings. Six excavators dug through the ruins.
