Description
I give an overview of recent observational results constraining the local HI accretion rate. These are mostly based on data from the WSRT HALOGAS survey, which recently had its public data release. Using the limits derived from HALOGAS data I discuss the parameter space that future HI surveys on SKA precursors and SKA itself must cover in order to further constrain the local cold gas accretion rate.
