descriptions allow the delineation of several distinct agricultural regimes.
In coastal west Africa, from modern Liberia north to Senegambia, rice was
the main staple, grown in a complex agronomic system that produced
high yields but required considerable labor. Rice growing along the coast
and in marshy areas, as well as along river basins farther inland, was
supplemented by other crops in less well watered areas. Millet and sor-
ghum were particularly important. They were later supplemented by
exotic crops such as American maize and cassava.
Where ecological conditions permitted it, stock was raised, and cattle
were plentiful in the drier inland areas. Other parts of
the
region were less
favorable to cattle raising, and small stock, such as chickens and pigs,
provided much of the dietary protein. Fish were consumed fresh along the
entire African coast and near fish-bearing rivers and were preserved by
salting or drying for areas without substantial fishing areas.
Africans produced beer and, in most areas, made wine from a variety of
palm oils. Tree crops and peanuts were especially important for edible oils,
and arboriculture was an important activity in all regions.
Lower Guinea had a different regime of crops from Upper Guinea,
making much more extensive use of yams and, later, exotic root crops,
such as cassava. Rice
was.
fairly rare in this region, though millet and
sorghum and, later, American maize provided the basic grain crops. Most
of the region was not favorable for cattle; small stock provided protein,
along with fish. Palm wine was especially important as a beverage, while
palm oil figured prominently in cooking.
The Angola region also had less rice cultivation, though some
was
grown
along the lower course of the Zaire River in Kongo. Millet and sorghum
were
gradually replaced by American maize and then often by cassava in the
seventeenth and eighteenth centuries. Stock raising was variable; some
highlands regions, such as Ndongo, were major cattle-raising areas, while
other regions, such as the majority of the kingdom of Kongo, produced few
cattle. As in other parts of Africa, fish
—
caught fresh along rivers and the
coast, or dried and salted elsewhere
—
were critical in the diet. Angolans,
like Africans in other regions, drank palm wine and various brewed grain
drinks and used palm oils extensively in cooking.
Although the exact mode of
food
preparation varied widely, some gener-
alizations are appropriate for Atlantic Africa. Grain crops were mostly
eaten in the form of stiff gruels or porridge. Typically, in the case of
American maize, millet, and sorghum, the grain was pounded into fine
powder and then boiled to the desired consistency. Rice was boiled with-
