World Regional Geography
Chapter 9:
A Geographic Profile of
Sub-Saharan Africa
Sub-Saharan Africa
9.1 Area & Population
• Second largest land area of all the major world regions
– Covers 17.4 million square miles (Twice the size of the U.S.)
• Population of 749 million (2007)
– Overpopulated in areas, yet much of region is sparsely populated
– Average population density is slightly more than that of the U.S.
– Rate of population increase is 2.5 percent per year
• Preference for Large Families
–
–
–
–
Extra hands to perform work
Ability for parents to be looked after when old or sick
In the case of girls, to receive “bride wealth”
Large families convey status
• Birth rates have been dropping in every country
in the region over the past past two decades

9.1.1 Africa’s Population Prospects
• Africa has the world’s youngest population
– 43% of the region’s people are under 15 years of age
• Malthusian Scenario
– 1 Percent Gap
• Population has had growth rate of about 3% since 1960s
• Food production has grown at only about 2% annually
• This is the only world region where per capita food
production is declining
– HIV/AIDS
• Possibly a Malthusian “check” to population growth

9.2.1 The Landscapes of Africa
• Most of Africa is a vast plateau, or series of plateaus
– Typical elevation of more than 1,000 feet, though in
places elevation rises to 5,000 feet and higher
• The character of African rivers
– Rapids and waterfalls block navigation a short
distance inland
• Great potential for hydroelectric energy
– Africa’s discontinuous inland waterways are
interconnected by railroads and highways

9.2.2 Africa’s Biomes and Climates
• Equator bisects Africa, so about two-thirds of the region
lies in the low latitudes, having tropical climates

9.2.3 Living off the Land
• Most productive lands are on river plains, in volcanic
regions, and in some grassland areas of tropical steppes
• To support growing populations, fallow periods have been
shortened, and the lands pressed to yield more crops
• Sub-Saharan Africa’s soils favor subsistence agriculture
and pastoralism
– Half of the region’s population practices these livelihoods

9.2.4 Africa’s Wildlife
• Africa has the planet’s most spectacular and numerous
populations of large mammals
– Tropical grasslands and open forests
• Habitats of large herbivorous animals
– Elephant, Buffalo, Zebra, Giraffe, and many species of Antelope
• Carnivorous and scavenging animals
– Lion, Leopard, and Hyena
– Tropical rain forests
• Abundant species of insects, birds, and monkeys
– Streams and rivers draining the forests and wetter savannas
• Hippopotamus, crocodile, and a great variety of fish
• Home to some of the world’s most extraordinary
and successfully managed national parks
– International tourism to these parks is a major source
of revenue

9.3 Cultural & Historical Geographies
• African continent was the original home of humankind
• After 5000 B.C.E., indigenous people were responsible
for agricultural innovation in four culture hearths:
– Ethiopian Plateau
– West African Savanna
– West African Forest
– Forest-Savanna Boundary of West Central Africa
• Domestication of important crops
– Millet, sorghum, yams, cowpeas, okra,
watermelons, coffee, and cotton
9.3.1 The Languages of Africa
• Peoples of this region speak more than 1,000
languages, which generally belong to one of four
broad language groups:
–
–
–
–
Niger-Congo
Afro-Asiatic
Nilo-Saharan
Khoisan
• The African Union, the continent’s supranational
organization, uses 6 official languages
– English, French, Portuguese, Spanish,
Swahili, and Arabic
Languages of Sub-Saharan Africa
9.3.2 Africa’s Belief Systems
• Spiritualism is extremely strong, but spiritual affiliations
and practices are more interwoven and flexible than in
most other world regions
– Not uncommon for family members to follow different faiths,
or for an individual to change religious beliefs and practices
in the course of a lifetime
• Dominant Religions of Africa
– Islam
– Christianity
– Indigenous African Religions (Animism)
Religions of Sub-Saharan Africa
9.3.3 The Origins and Impacts of Slavery
• Over a period of 12 centuries, as many as 25 million people
from sub-Saharan Africa were forced to become slaves,
exported as merchandise from their homelands
• The trade began in the 7th century, with Arab merchants using
trans-Saharan camel caravan routes to exchange goods
• Slave traffic
– Provided motivation for European commerce along African coasts
– Largest slave traffic was the European controlled slave trade
– Transatlantic slave trade peaked between 1700 and 1870
• 80% of an estimated 10 million slaves made the crossing
• More than 10 million others probably died
• Slavery has not yet died out in the region
– Enslavement of children persists in West Africa
Slave Export Trade Routes
9.3.4 The Impact of Colonialism
• European colonialism began to overshadow and inhibit the
growth of indigenous African civilizations in 16th C.
• Portugal was earliest colonial power to build an African empire
• Conference of Berlin in 1884-1885
– European powers carved up Africa
– Modern national boundaries do not correspond with ethnic boundaries
• Nigeria as the “Mistake of 1914”
• European colonization had both positive and negative
impacts on the region
• Most countries still have important links with their
former colonial powers
Colonial Rule in 1914
9.4 Economic Geography
• Sub-Saharan Africa is characterized by great poverty
– 25 of the world’s 30 poorest countries are located there
– All economies except South Africa’s are underindustrialized
• Africa’s place in the commercial world is mainly that
of a producer of primary products
– Cash Crops
– Raw Materials
• Social and structural problems contribute to the
region’s underdevelopment
– Most African societies lack a substantial middle class
and the prospect of upward economic mobility

9.4.1 Agriculture
• Per capita food output in most of Sub-Saharan Africa has
declined or remained flat since independence
– Malnutrition afflicts almost half the region’s children
– Rapid population growth and drought are responsible
– Many regimes have invested more in their militaries than in getting
food to their citizens
– Governmental preference for cash crops over subsistence food
crops
• Export Crops
– Grown on small farms rather than on plantations / estates
– Most valuable export crops are:
• Coffee, Cacao, Cotton, Peanuts & Oil Palm Products
– Secondary Cash Crops
• Sisal, Pyrethrum, Tea, Tobacco, Rubber, Pineapples,
Bananas, Cloves, Vanilla, Cane Sugar & Cashews
9.4.2 Mineral Resources
• Notable Mineral Exports
–
–
–
–
–
–
–
Precious metals and precious stones
Iron alloys
Copper
Phosphate
Uranium
Petroleum
High-grade iron ore
• Destined principally for Europe, the U.S., and China
• Mining has attracted far more investment capital to Africa
than any other economic activity
Minerals, Oil Pipelines and Transportation Links
9.4.3 Africa’s Fragile Infrastructure
• Poor Transportation Hindering Development
– Few countries can afford to build extensive new road or rail
networks, and much of colonial infrastructure has deteriorated
– Contributes to famine, with the inability to transport crop
surpluses to parts with chronic food shortages
– Contributes to high costs of agricultural inputs (i.e., fertilizers)
• Bridging the Digital Divide
– Critical shortage of telephone, fax, e-mail, and other
communication technologies
– Internet Cafés
– Mobile Phones
Ferries for River Crossings Without Bridges
9.4.4 Africa in World Markets & Economies
• Commodities boom brought annual economic growth
rates of about 5% to 16 Sub-Saharan African countries
• Many countries outside the region have effectively closed
their doors to African imports
– Subsidies, high tariffs, and/or low quotas imposed on
agricultural products or manufactured goods
• Africa’s Debt
– Forgiveness of $40 billion of debt by G-8
– China’s engagement with the region
• Pledge of $20 billion in infrastructure and trade financing
9.4.5 A Legacy of Failed States
• Failed-State Syndrome
– Pernicious process of economic and political decay
that is eating away at some African countries
– Some countries are little more than “shell states”
– 9 of world’s 15 most corrupt countries are in this region
– Donor Democracy
• Leaders make just enough concessions to win
outside aid without instituting real reform
9.5 Geopolitical Issues
• Sub-Saharan Africa is often judged as marginal in world affairs,
but the region deserves and is receiving increased international
attention
– Humanitarian problems
– Global implications of its public health and environmental
situations
– Problems in the management of Africa’s natural resource
wealth, its oil reserves, and concerns over terrorism
– Terrorism Hot Spots
• Kenya, Somalia, Djibouti, Niger, Chad, and Mali
– HIV/AIDS
• Link between U.S. and Africa via air traffic routes
• Potential AIDS-related political instability or civil wars
