What are the problems of urbanization?

Problems of urbanization:

• Shortage of housing, vertical expansion and growth of slums are characteristic features of modern cities of developing countries.
• The decreasing employment opportunities in the rural, as well as smaller urban areas of the developing countries, consistently push the population to the urban areas. 
• The enormous migrant population generates a pool of unskilled and semi-skilled labour force, which is already saturated in urban areas.
• Insufficient financial resources fail to create adequate social infrastructure catering to the basic needs of the huge population.
• The large urban population in developing countries not only uses but also disposes off a huge quantity of water and all types of waste materials. Many cities of the developing countries even find it extremely difficult to provide the minimum required quantity of potable water and water for domestic and industrial uses.
