%X The measurement of the star formation rate density of the universe is of prime importance in understanding the formation and evolution of galaxies. The [O II] ƛ3727 emission-line flux, easy to measure up to z ≈ 1.4 within deep redshift surveys in the optical and up to z ≈ 5/4 in the near-infrared, offers a reliable means of characterizing the star formation properties of high-z objects. In order to provide the high-z studies with a local reference, we have measured total [O II] ƛ3727 fluxes for the well-analyzed local sample of star-forming galaxies from the Universidad Complutense de Madrid Survey. These data are used to derive the [O II] ƛ3727 luminosity function for local star-forming galaxies. When compared with similar luminosity densities published for redshift up to z ≈ 1, the overall evolution already observed in the star formation activity of the universe is confirmed.
