"The migration takes place due to several reasons which I have stated above. People from rural areas are mostly uneducated and they end up getting low income job which forces them to build a shelter near to their office and those shelters multiplies in fraction of time and takes a permanent shape, politics is crocked and most of us are aware of it, be it any country. This all is the reason of slow economic growth."
You nailed it! Your post reminded me of a research project I conducted in school regarding solutions to effectively create housing for homeless families and how architecture could help with it. One of the challenges goes beyond architecture, however. During my interview with housing authority officials, the location of the housing is usually an issue and its proximity to employment. They noticed a trend where they provide a house to a family and this family will eventually sublet the unit and would again end up creating a temporary shelter in slums. It became a cycle and the result of my research became pessimistic.
You're right, architecture can help by working with authorities to address these issues while creating an urban masterplan and of course providing the basic amenities to ensure residential buildings are sound and habitable.
Thank you @discoveringarni for appreciating.
Yes, these things happen. I remember my seniors during project used to say that these people won't live here anyways they will ultimately sublet other people and will again construct a temp. shelter. This is a huge problem which is hindering the development. You are absolutely right , its's actually a vicious cycle- never ending.
The budget, masterplan and strict policies and execution without corruption could help remove slums problem as there are many social problems which resides there along with people.
Thanks again, have a productive week:)
