Hi Arun
You wrote the introduction about poverty, the question is about slums.
You can start like -Slums are an omnipresent reality for most of the major cities of India and various efforts have been made by the government to address the issue.
Issues are discussed in a decent manner.
Measures needed more points like instead of forced evictions, authorities should plan an in-situ upgrading approach. Easy financing and loaning options at affordable interest rates for upgrading, building and extension of the existing shelter should be made available.
Good conclusion.
