We present a method to obtain the history of the local star
formation rate (SFR) by using the G dwarf metallicity distribution.
The method is tested by simulations and applied to the solar
neighborhood. We find strong evidences of two events of star
formation: a big burst 8 Gyr ago, and a lull 2-3 Gyr ago. We also
find evidences of a present star formation burst. These events
agree with some previous determinations of the history of
the local SFR.
