Within the village co-operatives, Khmer Rouge militia regularly killed those they deemed to be "bad elements". A common statement used by the Khmer Rouge to those they executed was that "to keep you is no profit, to destroy you is no loss." Those killed were often buried by the fields, to act as fertiliser. During the first year of Khmer Rouge rule, most areas of the country were able to stave off starvation despite significant population increases caused by the evacuation of the cities. There were exceptions, such as parts of the North-West Zone and western areas of Kompong Chhnang, where starvation did occur in 1975.
