These outflows ca n be driven by radiation/winds but also by the interaction of the radio pl asma with the ISM. Understanding the origin and quantifying their impact r equires to trace their location and derive their physical conditions (dens ity of the gas, mass, mass outflow rate and kinetic energy of the outflow etc.). Particularly interesting has been the finding that in the first pha se of their life, jet in radio galaxies can be particularly effective in d riving such outflows. This crucial phase is at the heart of the idea of fe edback, therefore particularly relevant for studying feedback in action.\n  \nIn this talk, I will present some of the results we have obtained to trace jet-driven HI and molecular gas outflows down to scales ranging f rom hundred to tens of pc. The impact of low-power radio jets will be disc ussed and the comparison with the predictions from numerical simulations w ill also be presented.\nOutflows of up to few hundred Msun/yr have been fo und in molecular gas using ALMA while the HI observed with VLBI is showing that the outflowing gas is clumpy as also predicted from numerical simula tions. I will describe the kinematics of the gas and its conditions and th e relevance they may have for feedback.     END:VEVENT END:VCALENDAR
