Preview
People and Their Environment- Rainforests and the
Congo River and its tributaries dominate the landscape of
Central Africa. Population is scattered throughout the region.
Government and Economy- Transition from colonial rule
has been difficult. The region’s water, forest, and mineral
resources are only partly developed.
Society and Culture- Life in forests, on farms, and in cities
creates different customs among the region’s many ethnic
groups.
Reach Into Your Background
Make a list of things you would need to bring if you were planning a journey by foot through the African rainforest.

Partner Activity
Work with a neighbor and compare your answer with theirs. What things are the same and what things are different? (3 minutes)
Key Ideas- Climate and Vegetation
The Equator cuts through Central Africa.
Heat and abundant rain have created a
rainforest that dominates the region.
Central Africa is the continent’s most
lightly populated region.
The region’s water, forest, and mineral
resources are not yet developed.
Key Term
Equator- An
imaginary line
circling the
earth halfway
between the
North and South
Poles, dividing
the earth into
two
hemispheres.
People and Their Enviroment
All the countries of
Central Africa lie on or
near the Equator.
Their location
influences their
climate and
vegetation.
It is usually hot and
wet year round.
Climate and Vegetation
Average annual
temperature is near 80˚
Fahrenheit.
Most of the region gets
more than 80 inches of
rainfall per year.
Rainforests in Central
Africa cover an area four
times the size of France.
Climate and Vegetation
Few forests have been
cut down because
they are difficult to
reach.
Roads and railroads
are costly to build and
maintain in a region
with such heavy rains.
Climate and Vegetation
Despite having rich plant and
animal life, rainforest soil is
poor.
Heavy rains wash away
nutrients in the soil. When
the soil is cleared of trees,
underbrush, and vines,
leaching removes more
nutrients.
The soil becomes unsuitable
for farming.
Climate and Vegetation
As you move away
from the Equator
to the North or
South, rainforests
disappear.
Congo River: Lifeline for a Region
Fifth longest river in the world.
The river and its tributaries provide
miles of navigable water running
through the region’s interior.
Waterfalls and rapids can make
travel difficult.
Many countries are developing the
Congo River so that dams and
power plants can be built and the
river can be a source of
hydroelectric power.
A Sparsely Populated Region
Central Africa has fewer
people living in it than other
parts of Africa.
This is especially true of rain
forests. Those who do live in
rain forests often live along
riverbanks or near rail lines.
Poor soils and difficulties of
clearing land have kept
people out of these areas.
Questions
1. What is the weather like for countries
that lie on or near the Equator?
2. Boats on the Congo River provide
vital links for river settlers. Besides
transportation, how can the river be
used?
Answers
1. What is the weather like for countries that lie on or
near the Equator?
Countries that lie on or near the Equator are usually hot and
wet year round.
2. Boats on the Congo River provide vital links for river
settlers. Besides transportation, how can the river be
used?
The river can be used for fishing, bathing, and washing
clothes.
Key Ideas- Government and Economy
Nations in Central Africa have had a difficult
transition from colonial rule.
Central Africa has rich water, forest, and
mineral resources awaiting development.
Many regions in Central Africa are moving
towards democracy and multiparty elections.
Central Africa has an export economy.
Economy
Most people in the region
are farmers.
Tropical forests provide
timber.
Copper is the most
important mineral in the
region.
Other resources include
oil, natural gas, coal,
uranium, tin, zinc,
diamonds, and gold.
Central African Countries
Central African countries
need to develop their
natural resources more
effectively.
Agricultural production has
declined in many areas.
As a result malnutrition—
the condition of not
getting enough nutrients
from food—has increased.
Central African Countries
Forests are being cut down
for timber.
Mining destroys the
landscape.
Organizations around the
world are working to find
ways to help Central
Africans improve their use of
resources and protect their
environment at the same
time.
Key Term
World Bank- The
World Bank is an
international
financial
institution that
provides loans to
developing
countries for
capital programs.
Key Term
International
Monetary Fund
(IMF)- Is an
international
financial institution
that promotes
international trade
by increasing the
stability of the
major currencies.
Questions
1. Why does it benefit a nation to
process its own minerals?
2. Organizations around the world
are working to find ways to help
Central Africans do what two
things?
Answers
1. Why does it benefit a nation to process its own
minerals? Nations can make more profit selling their own
processed minerals.
2. Organizations around the world are working to
find ways to help Central Africans do what two
things? Organizations want to help Central Africans improve
their use of resources and protect their environment.
Key Ideas- Society and Culture
Central Africa is home to diverse
people speaking many languages
and following different customs.
The region’s diversity is heightened
by different ways of life in forests, on
farms, and in cities.
Society and Culture
Central Africa has many
ethnic groups, each with
different languages and
customs.
A unifying factor is the
French language, spoken
and read in the former
French colonies.
Most Central Africans
live in villages, but cities
are growing.
Technology Allows for Exploration
Exploration and
development in Central
Africa was nearly
impossible for European
explorers prior to the
1800s .
The development of
new medicines that
could fight diseases like
malaria allowed for
further exploration.
Coming Together Through Soccer
Soccer is a popular
sport throughout Africa.
National teams unite
people from many
backgrounds.
Sports are just one way
that people can come
together.
Questions
1.Where do most people in
Central Africa live?
