Always wanted to suggest or do something for the locality you live in Mumbai, but did not know where to begin or what to do.
I just posted over at my tumblr page a post on how to submit or enquire about projects for development or beautification of your area.
With barely twenty days left for the deadline, it does not leave much time and does not help that the mail is so late in the day. But it serves as a useful reference point and maybe more if you want to be the person who makes a difference.
If you are not a resident of Mumbai, whichever place you are a resident of in India, enquire with your local body, municipal corporation or equivalent and get involved. An active involved local community will result in safe, healthy and better places to live in.
