Eaten like potatoes. Other major crops include maize*, potatoes, beans, millet (a type of grain), bananas, peanuts, rice, and wheat. During the colonial period, Angola grew several profitable cash crops* for export, including cotton and coffee. These commercial crops declined dramatically after independence as a result of changing economic policies and years of civil war. Nevertheless, crops such as tobacco, coffee, bananas, sisal, cocoa, sugarcane, and cotton are still grown commercially. Subsistence farmers in Angola raise a variety of livestock, including sheep, goats, pigs, and poultry.

Along the southern edge of the Highland Plateau lie the Saharan Atlas Mountains. Beyond the mountains is the vast Algerian Sahara. At the heart of this desert loom the Ahaggar Mountains, a volcanic chain that includes Mount Tahat, the highest peak in the country (9,573 feet). Although the desert includes more than 80 percent of the country’s total area, only about 3 percent of the population lives there. Most inhabitants have settled near oases, where deep wells tap into underground springs to provide irrigation for crops of grain and dates.

This demand led to many experimental breeding programs. For example, the native cattle of southern Ethiopia, which can survive in a semidesert environment, were crossbred with cattle from northern Europe that produce large quantities of milk and beef. Such practices increase production of beef and milk in the short term, but crossbreeding may have serious long-term effects on the ecosystem. The unique genetic makeup of local breeds of livestock may be lost in the process, and new breeds may have less resistance than the native animals to diseases or to environmental stresses such as drought.
