I will present the results of a study on the molecular gas spatially resolved star-formation relation for a sample of low-luminosity active galactic nuclei in the context of the NUclei of GAlaxies (NUGA) project. Spatially unresolved studies of the star-formation relation have been and are still useful for characterizing global disk properties, but understanding the mechanisms behind the star formation requires resolved measurements. The recent high-resolution observations are allowing to study the star-formation relation to its intrinsic spatial scale, i.e. the size of giant molecular clouds (~10-150 pc). With our NUGA (PdBI+SMA) CO(1-0), CO(2-1), and CO(3-2) sensitive high-resolution maps on scale of 20-200 pc, I have investigated the correlations and slopes of the star-formation relation as a function of spatial resolution. Here I present the results of this study, as a preview of what's coming with the explosion of ALMA data. I will also mention the Dustpedia project, a Definitive Study of Cosmic Dust in the Local Universe, based on Herschel Space Observatory and Planck Telescope databases.
