This film focuses on three types of subsistence patterns: foraging, horticultural/ agricultural, and pastoralism. The Ju'hoansi who live in the Kalahari Desert in southern Africa are a prime example of the hunter/gatherer-foraging subsistence system. The most common form of horticulture is slash-and-burn cultivation, which relies on human power and has limited productivity yield. The third subsistence system is pastoralism, the managing of herds of animals. Many pastoralist societies live at such high altitudes that little agricultural activity can occur. The society studied in this program is The Yolmo of Nepal.
