Infrastructures are often self-built from wood, cardboard, plastic, rubbish roofs and bricks. Most of them lack windows, doors, adequate ventilation and are often small living spaces shared with one or two other families. The floors are earthen. These places are not livable for humans, yet slum dwellers have no other alternative. Slums are a major failure because they lack infrastructural conditions that affect slum dwellers physically, socially and emotionally. Some solutions, including demolition and improvement, have been practiced but have often failed, because they do not include the existing community. If the housing conditions are resolved, it will no longer be a slum. Many of us are unaware of the reasons for existing settlements. The reason for the growth of slums is the migration from rural to urban areas by people seeking better opportunities in cities than agricultural jobs. Slums clearly represent the disproportion between migration to cities and economic growth within cities. However, migration creates a high demand for housing, as a result there is a housing shortage, which forces people to move and live in urban areas of the city. The definition of a slum presented by the Challenge of Slums: Global Report on human settlements 2003, a report by Un-Habitant is: “A run-down area of ​​a city characterized by substandard housing and squalor and lacking security of tenure.” These existing communities are often densely populated and ignored by the rest of the government and the rest of the world. Slums are densely populated, this density in cities is growing rapidly, and basic services do not meet the requirements.
