(Where you are, action needs to be performed there) Yes. You can sit in an AC room and solve the problem of those who live in wilds of Koraput? Why not? As long as you actually solve their problems. As long as you help India from NY city thats fine also. As long as you look onto earth from heavens and make sure the earthlings doing ok or not that would be fine also, except noone has done that ever. Do something while you are in earth and do something while you are in the wild.
