  Studies of disks around young brown dwarfs are of paramount importance to our
understanding of the origin, diversity and early evolution of sub-stellar
objects. Here we present first results from a systematic search for disk
emission in a spectroscopically confirmed sample of young objects near or below
the sub-stellar boundary in a variety of star-forming regions. Our VLT and Keck
L'-band observations of the sigma Orionis and TW Hydrae associations suggest
that if a majority of brown dwarfs are born with disks, at least the inner
regions of those disks evolve rapidly, possibly clearing out within a few
million years.
