[Star Trek TNG] In the time when Picard is captain of the Enterprise, would an evacuation of earth be possible? How would the starfleet, earth's allies etc. (re)act?

If there'd be some doomsday scenario for Earth, would it be feasible (with that massive population) and if yes, in what frame of time? 

I know there have been evacuations done by the starfleet earlier but to a much smaller scale on other planets. Is there any emergency plan for Earth-bound ~~humanity~~ intelligent life?

Evacuating Earth would be a logistical nightmare and couldn't be performed in a short amount of time (less than a month).  You would pretty much have to recall the entirety of Starfleet and any other ship that you could manage to bring into the effort.
