Abstract: In the last 30 years, observations of the gas and dust surrounding young precursors of solar-type stars have begun to reveal their physical and chemical properties. In the meantime, the number and diversity of observed exo-planetary systems has dramatically increased. Dust and gas discs have been intensively studied by existing millimeter/submilliter (mm/submm) facilities because this domain of wavelength is very well suited to observe rotational molecular lines and thermal dust emission in these relatively cold objects. With the advent of ALMA, observers will be able to characterize the gas and dust properties not only in the cold outer part of discs but also in the warmer inner part where planet formation may occur. Many important results have prepared the ALMA era. In this Keynote lecture, I have chosen to focus on a few of them in order to show how they have gradually refined our understanding of the disc properties, the final goal being to unveil the initial conditions of planet formation thanks to ALMA capabilities.
