As per UN census, the rate of population growth is substantially increasing day by day in almost all the cities of the world, including the Mega cities. At this moment the rate of population growth in the cities World Wide is about 48%, which in 30 years will rise to 60%. The rate of population growth in the cities will be specially high in the least developed countries and the developing countries. If we look at the Mega cities (more than 10 million people), we will find that most of the Mega cities are in Asia like Dhaka, Calcutta, Mumbai, Delhi, Karachi, Jakarta, Metro Manila, Beijing, Shanghai, Tokyo, Bangkok etc. That is how in our country also rate of urbanisation is increasing alarmingly . In our country, people from different rural areas are rushing towards the cities at a very high rate. Most of them are from low-income group and this rate will be getting higher in near future also. It has now become a big challenge for the Development Authorities like KDA and other Development Authorities to provide necessary facilities to those people in the cities. As a result, it is seen that we are facing the challenges of “Urbanisation of Poverty”. In our country it is seen that in any cities more than 50% people are migrant workers and their families. In this type of least developed countries, due to these migrant workers and their families, cities are becoming larger but our greatest challenges are becoming “Urbanisation of Poverty”. Therefore providing safe drinking water, clean air, shelter or housing, employment and health care are becoming our greatest challenging tasks. At the same time as bi-product urban agglomerations and environmental degradation are taking place.
