Slums had been perceived as areas prone to a lot of challenges especially overcrowding,    poverty, poor sanitation, crime, violence, HIV/AIDS pandemic, marginalization, and segregation    among others among others. Due to such stereotypical convention and misinformation, slums    had been neglect and not considered as part of the city despite the major contribution it offers,    especially in the early days. A number of theories have been developed about slums without due    consideration of the underlying factors to such neighborhoods’. At least three factors have been    put forward in trying to understand why such settlements crop up. These include: colonial system    of planning, system of governance and rapid population growth even though such may not be    applicable in other countries. Discovering that such conditions were no longer improving,    various governments came up with various strategies in try to contain it, namely: demolition and clearance, relocation to public housing.
