The Haya farm is an integrated enterprise. A typical household, cultivates food crops (bananas and beans) cash crops (mainly coffee and beer bananas) and also supports itself with income from extra-agricultural enterprises, such as fishing, house construction, furniture-making, tailoring, watch repair, brewing, distilling, village bars, petty trading, traditional medicine. Village traders and artisans supply all the locally available goods and services. Family visits into and out of the villages provide an injection of commodities either not available locally or too expensive for everyday use.
