Try to transform your vector areas into a raster map, afterwards you are able to use r.statistics (now, former polygons as the raster base map and desired raster as the cover map)...that should work!

I want to calculate the average value of a raster but instead for all pixel values, I want to calculate the average of pixel values that are inside each polygonIs this possible in GRASS? If yes, how?
