Africa Notes
Geography….
► About
50
countries
► 1/3 of all the
world’s
countries
► 2nd largest
continent in
land area
Continent of Plateaus….
►
►
►
►
Africa is a giant
plateau
Plateau - flat
landmass higher than
the surrounding land
with at least one steep
side
Narrow coastal plains
extend inland less than
20 miles
One plateau follows the
other as the land rises
from west to east in a
series of steps
Continent of Plateaus…
►
►
►
►
►
Escarpment – steep
cliffs or slopes,
separate the plateaus
The highest and broadest
plateaus and escarpments
lie in the south and east
Rivers turn into
cataracts – waterfalls,
as they flow over the
escarpments
Because of plateaus, Africa
has the highest overall
elevation of any other
continent
The average elevation is
2000 feet above sea level

creates a Y
shaped trench
3500 miles long

famous of the rift’s
volcanoes

Pangaea….
► Pangaea
 Theory that all the
continents were
connected to form
one large continent
 Scientists believe the
Great Rift Valley was
created during violent
movements that
separated the continents
and caused them to drift
apart 180 million years
ago

Climate….
►
Western Africa
 Lies within the tropics

Population Distribution….
 Uneven population
distribution due to
physical geography
► Sparsely
populated:
 Deserts
 Mountains
► Densely
populated:
 Around lakes and
rivers
 Fertile soil
 Good climates
Problems Facing the Population…
 Due to a growing
population, many regions
in Africa are struggling to
feed their population
 Food production has
declined due to:
► Loss
of soil fertility
► Droughts
 Famine and malnutrition
kill many Africans
► Famine
- severe food
shortage for an
extended period of time
 Only about 40% have
clean drinking water
Problems….
 Many diseases
► AIDS
has become an
epidemic - a disease
affecting many
persons at the same
time, and spreading
from person to
person in a location
 Poor medical care due
to:
► Lack
of doctors

supplies and equipment
 Very low Gross Domestic
Product (GDP) - total
amount of goods and
services produced in a
county in a year

from region to
region

► South Africa - $10, 270
Urbanization….
►
►
►
►
Urbanization - the movement of people from rural
to urban areas
Africa is the least urbanized continent but it is urbanizing
at the fastest rate
Most cities are located along rivers or near natural
resources
People often move to cities in search of jobs
 Housing shortages
 No electricity or running water
History….
►
Great kingdoms
ruled areas of West
& Central Africa
 Trading sites
 Gold, cloth, slaves

Europeans began
trading with African
societies for slaves
 Europeans sold
enslaved Africans to
American colonists
 The slave trade existed
for a long time
► Disrupted
families &
societies
► Coastal states became
more powerful than inner
savanna
 The triangular slave
trade:
► Europeans
traded with
Africans for
slaves in
exchange for
goods like
weapons
► Slaves were taken
from Africa to the
colonies in the
Americas
► Raw materials
grown in the
Americas were
taken to Europe
to the
manufacturing
plants
 Millions died during
the “Middle
Passage”- ocean
journey from Africa
to the Americas
History cont….
 David Livingstone
► Scottish
doctor and
missionary
► One of the first
Europeans to explore the
interior of Africa
► For 30 years, he explored
and set up Christian
missions
► Sent detailed reports back to
Great Britain of the exotic
wildlife and people
 The stories from Africa made
people very curious
European Colonization
► Mid-1800s
– slave
trade was ending
► Europe was
industrializing
and needed
resources
 Europeans sought
control of fertile
African territories
and resources
Scramble for Africa….
 European nations
scrambled to make their
claims in Africa
 By the 1800s, European
nations divided up
Africa and colonized it
 In 1885, 14 nations met in
Berlin to partition- or
divide, Africa
 By 1914, European
nations controlled 90%
of Africa
 Europeans controlled most
of Africa until the mid to
late 1900s

independent
state in west
Africa

Housing
Housing South African slums
1) Market in West
Africa selling
fruits
2) Farmer and his
laid-out field
(needs to be
located near
water for
irrigation
3) Farmer plowing
his field to grow
crops (lack of
technology)
4) Typical business
woman in South
Africa where
opportunities
are greater
5) Copper mining
in Central Africa
Agriculture….
 Most Africans still rely
on agriculture to make
a living
 Cash crops - grown to
make a profit
 Millet & sorghum are
staple crops – drought
resistant
 Other staple crops –
cassava, yams, corn
 Dual economies – some
goods produced for
exportation while others
are produced for local
people
Agriculture cont…
 Farming methods
► Commercial
farmingfarming organized as a
business produce cash
crops
► Shifting farming- farmers
move every one to three
years to find better soil
► Sedentary farmingfarming conducted on
permanent settlements
 Problems
► Most
people cannot afford the
machinery, technology and
fertilizers to increase food
production
► Food shortages are a
constant problem
 Important economic
activity
 Very dangerous
 Work long hours
 Many poor Africans
work in the mines to
support their families
► Mineral
wealth has
made South Africa
one of the richest
regions in the area
► Most black South
Africans do not
benefit from this
because the mines
are owned by
white South
Africans or foreign
companies
Mining….
Industrialization….
 Manufacturing is not a big
part of the economy
 Obstacles to
industrialization
►Lack
of capital - tools
and equipment used in
factories
►Political conflict (within
countries and between
neighboring ones)
►Not enough skilled
workers
Environment….
► Famine




is caused by:
Rapidly growing populations
Lack of capital (tools and equipment)
Overdependence on cash crops
Desertification- transformation of arable (fertile)
land into desert
► Using
land too much for grazing and farming causes erosion
► Droughts have impacted this too
 Civil War is the biggest cause of famine
► Used
food as a weapon by burning the fields of their enemies
► Relief agencies like the Red Cross would send food but it was often
stolen by rebels or warlords
 Example - the movie Black Hawk Down was set in Somalia
 The destruction of
forests for:
► Wood
to export
► Burn forests to clear
land for farming or
grazing
► Fuel
 Results of deforestation:
► Deforestation
may
make the earth hotter
 Carbon dioxide holds in
more heat than oxygen
 Increase in carbon
dioxide (since plants
turn carbon dioxide into
oxygen)
► Plants
and animals are at
risk for extinctiondisappearance from the
earth
Deforestation…
Deforestation cont….
► Protecting
rain forests and endangered wildlife
 As the population grows, farmers need more land for
farming
 Taking land from grasslands and forests where animals live
 Many animals are becoming endangered because:
► Humans
have pushed into the animals’ natural habitats –
living areas
► Increase in hunting:
 Poaching – illegal hunting
 Elephants and rhinos (Tusks and horns are very profitable)
 Some countries have made huge game preserves to protect
animals
 Ecotourism- tourism based on the environment
 Ecotourism has increased visits to preserves
 Some Africans object to preserves because they need the
land and often don’t profit from ecotourism
Current Issues….
► Slow
economic development
► Rapid population growth
► Internal war & conflict
► Deforestation
► Extinction of plants & animals
► Malaria & HIV/AIDS
► Genocide – intentional destruction of people
 Rwanda (1994)
 Hutu vs Tutsi
