“…One of the most outstanding challenges facing urban planning today -mainly in, but not limited to, the Global South-is how to cope with rapid urbanisation, inequality, informality, and environmental degradation (Parnell, Pieterse and Watson, 2009;Watson and Odendaal, 2012;Song, 2016). In "informal cities" of Africa, planning norms and procedures, many of which are relics of colonial pasts, often run counter to the (informal) everyday city-building practices (Watson, 2009(Watson, , 2011Nielsen, 2015a, 2015b;Onyebueke and Ikejiofor, 2017). Informality or the "state of exception from the formal order of urbanisation" (Roy, 2005, p. 147) vis-à-vis informal livelihoods, settlements, and practices often conflicts with planning rationality thereby limiting both the capacities of planners and the effective reach of plans to tackle these affected urban challenges.…”
