The improvement of the world needs to be highly contextualised. In fact, everything needs context to be relevant.The above video of Hans Rosling is mind-bending. At the 15 minute mark he talks about Africa and how we cannot provide a single solution to a problem like HIV/Aids. We need to provide a contextualised solution for each and every region being dealt with.This is true of almost every interaction that I have with businesses and individuals (local or foreign) wanting to target Africa. It's phenomenal how shallow our understand is of the vastness of the continent when it comes to culture, language, societal norms, likes and dislikes.Africa is not a country just as South Africa is not a reference to a region.Educate yourself.
