Africa south of the Sahara is
a region of enormous
natural resource wealth, and
yet many of its people live in
poverty. A study of the
region today will explain the
immense challenges Africa
south of the Sahara faces in
gaining economic
independence and stability
while finding the best use of
its natural resources, which
are key to the region’s
development.
Section 1:
The Economy
The physical
environment affects
people and their
activities. Africa south of
the Sahara is making the
slow transition from an
economy based on
subsistence farming to one
that is part of the global
economy.
Section 2: People and
Their Environment
Human actions modify
the physical
environment. Throughout
the region, human
activities—such as war
and deforestation—have
had a tremendous impact
on the environment and
have contributed to famine
and the starvation of
millions of people.

Transportation and Communications
Developments in transportation and
communications will have positive effects
on the region’s economy, but the physical
environment has made such development
difficult.

geographic challenges.
• Two important road systems: Trans-African Highway
and Trans-Sahara Highway

war and deforestation—
have had a tremendous
impact on the environment
and have contributed to
famine and the starvation
of millions of people.
Managing Resources
In Africa south of the Sahara, factors such
as poverty, population growth, war, and
drought have caused a severe strain on the
environment.
• Poverty and hunger are the biggest enemies in this
region.
Carrying Capacity in Africa
South of the Sahara
Managing Resources (cont.)

adding to the problem of famine.
• War continues to be a major cause of hunger and
malnutrition in Africa south of the Sahara.

Human Impact
Human activities have destroyed rain
forests, threatened wildlife, and raised
questions about land use in Africa south of
the Sahara.
• About half of the original tropical forests are gone.
• Deforestation and hunting threatens the region’s
wildlife.
Human Impact (cont.)
• Due to hunting and poaching, the elephant
population has dwindled to 600,000 from the
millions.
Challenges for the Future
As Africa south of the Sahara faces the
future, human activities continue to have
both positive and negative impacts on the
environment.
• Positive steps toward the future:
– Democratic reforms
– Efforts to encourage private enterprise
Challenges for the Future (cont.)
– Game reserves
– Ecotourism
– Protection of tropical forests
Slowly Industrializing
Protecting Endangered Species
• Most African countries have
set up large parks and game
reserves to protect endangered
species.
• These parks and reserves also
serve as a source of income for
the countries as tourists come
from around the world to see
Africa’s wildlife.
• Private enterprise has also
helped save endangered
species. For example, crocodile
farmers earn money selling
crocodile leather. However, they also release
crocodiles into the wild, increasing the population.
