Despite the importance of urban development, there are still unsolved contradictions within society and questions rise about the sustainability of modernization. In Addis Ababa too many citizens do not have access to drinkable water, health cover and education. A large part of the population live in slums, which cover 80% of the overall built surface. New infrastructures are planned without any regard to natural or urban surroundings. Water and air pollution is an issue, and yet there are no strong environmental policies.
