Which crops are commonly grown by rural households in the Kalahari?

In the Kalahari, nearly all rural households cultivate crops of corn (maize), sorghum, and pumpkins.1

However, agricultural success is frequently hindered by the region's arid climate and the constant threat of drought, which often leads to more crop failures than successful harvests. Because of these environmental challenges, few households are able to produce enough crops to meet their own subsistence needs. In more remote areas, these cultivated crops are often supplemented by wild food plants and the meat of game animals.123
