Slums have long represented a great development challenge as they are by definition areas in which the inhabitants lack fundamental resources such as adequate sanitation, improved water supply, durable housing or adequate living space. For centuries, demolishing these settlements was seen as the right thing to do, but most often such action resulted in thousands of people remaining without a roof over their heads. Now, businesses are stepping in and are seeking to take an alternative road, one that involves investing in the poorest neighborhoods instead of destroying them. An increasing number of entrepreneurs are lining up in places like India, Ghana, and Kenya to offer those living in slums many of the normal public services we take for granted such as access to clean drinking water, adequate sanitation and better housing. The ultimate aim is to provide all the same rights and amenities that you would expect in a normal residential area.
