As rapid urbanization creates complex environments that concentrate the risks and hazards of man-made and natural disasters, it also presents a vital advantage that must be exploited. Urban humanitarian emergencies by their very nature occur within the geo-political sphere of a governing body, the municipal government, and as such they are the responsibility of that body. It is the duty of the municipal governments to prevent and prepare for and respoond to humanitarian emergencies that may affect their citizens. Preparedness at the city level, therefore, remains a valuable area for development to mitigate the effects of humanitarian crises. Rapid urbanization now allows a greater proportion of the population to fall under a responsible municipal government and an opportunity to promote and advance urban planning around preparedness.
