Belgium is small, #141 on the list of countries by size, with 30,528 sq km(11,787 sq mi), and 250 sq km(97 sq mi) of that is water. With a population of 11,323,973 to feed, and only 44.1% agricultural land(arable land 27.2%; permanent crops 0.8%; permanent pasture 16.1%), they can't waste land. This may be a posh estate.
