  I calculate the action of a satellite, infalling through dynamical friction,
on a coplanar gaseous disk of finite radial extent. The disk tides, raised by
the infalling satellite, couple the satellite and disk. Dynamical friction
acting on the satellite then shrinks the radius of the coupled satellite-disk
system. Thus, the gas is ``shepherded'' to smaller radii. In addition, gas
shepherding produces a large surface density enhancement at the disk edge. If
the disk edge then becomes gravitationally unstable and fragments, it may give
rise to enhanced star formation. On the other hand, if the satellite is
sufficiently massive and dense, the gas may be transported from $\sim 100$ pc
to inside of a 10 to 10s of parsecs before completely fragmenting into stars. I
argue that gas shepherding may drive the fueling of active galaxies and central
starbursts and I compare this scenario to competing scenarios. I argue that
sufficiently large and dense super star clusters (acting as the shepherding
satellites) can shepherd a gas disk down to ten to tens of parsecs. Inside of
ten to tens of parsecs, another mechanism may operate, i.e., cloud-cloud
collisions or a marginally (gravitationally) stable disk, that drives the gas
$\lesssim 1$ pc, where it can be viscously accreted, feeding a central engine.
