The KWCLSS corpus was recorded at Kailge in Western Highlands Province, Papua New Guinea. For Ku Waru speakers who are living in their rural homeland, the local economy is largely a subsistence one, based on intensive cultivation of sweet potatoes, taro, and a wide range of other crops; raising of pigs; and use of locally grown materials for building houses and agricultural infrastructure. There is now also intensive engagement with the cash economy, based largely on growing of coffee for the world market and vegetables for sale to town dwellers.
