Africa is urbanizing faster than any other continent[35] and it is estimated that by 2030, more than one billion Africans will live in cities.[36] This rapid urbanization, coupled with the many interlinked and complex challenges as a result of climate change, pose a significant barrier to Africa's sustainable development.[37] Much of this Urban Development is informal, with urban residents settling in informal settlements and slums often on the outskirts of cities.[38] This phenomenon suggests that lower-income countries should be targeted in initiatives to increase infrastructural sustainability.
