An important part of the Gaia mission is devoted to the study of Solar System Objects. In this domain, ground-based observations can be favorably combined with the space observations and in some cases they appear as a unique support for completing the Gaia data. We have organized a workshop in Beaulieu/mer near Nice in October 2008 with the goal to discuss this topic. 26 participants attended this workshop, coming from several observatories in different countries. They have underlined different aspects of the ground-based observations related to the expected Gaia Solar System science. These aspects includes the determination of asteroid mass, shape and density, the measurement of Yarkorvsky effect, the astrometric follow-up of new objects, the improvement of astrometric measurements of ancient observations of natural satellites and those of the stellar occultation predictions.
