I will discuss AO-assisted integral field spectroscopic observations of the inner kiloparsec of nearby active galaxies, which reveal the presence of AGN-driven outflows of ionized gas. By resolving the inner 10-20 parsecs, we are successfully modeling the geometry and kinematics of the outflows in 3D. The mass outflow rates are 2–3 orders of magnitude greater than the accretion rates, but they are comparable to the estimated inflow rates to the central 10-25 pc, suggesting that AGN feedback suppresses accretion onto the SMBH. The outflows seem to form two distinct groups that differ by outflow power variations with radio flux. While powerful outflows (with kinetic powers > 1.0% Lbol) are observed in objects with extended radio jets, in the other AGN -in which the outflow power is less than 0.1% Lbol- the radio jet is weak and compact.
