A little note on the increased challenges existing within urban Africa caused by its population boom.

Urbanisation in many parts of Africa has "largely been translated into rising slum establishments, increasing poverty and inequality."  SSA (sub-Saharan Africa) cities are (assumingly very broadly) characterised by insufficient basic infrastructure.

84% of Africa's urban dwellers have access to potable water with 54% with adequate sanitation (AfDB et al., 2012). Broadly, 60% of Africans live in areas where water supplies and sanitation are inadequate.

With Africa's urbanisation increasing furthermore, infrastructural problems will put an increased amount of pressure on political responses to management of the issues it creates. Unless basic infrastructural needs are met, combined with a strong enough government to implement policy to deal with the issues that rapid urbanisation will have for the continent there could be serious implications for the poorer majority of those who live in urban Africa, particularly SSA.
