The truth is that there is a lot more to Africa than we tend to think—
both related to physical and cultural geography.
Let’s begin with physical geography. You’ve been working
on your Africa map, so you’re familiar with SOME of this.

Undergoing Steady Urban Growth - Tripoli, Libya
*Grasslands have been converted into agricultural
fields
*Urban expansion is especially notable in Libya
(shades of grey)
•Libya began using their oil resources when planting
trees along their Southern border in order to stop
desertification.

African Rain Forest
# Annual rainfall of up to 17 ft.
# Rapid decomposition (very humid).
# Covers 37 countries.
# 15% of the land surface of Africa.

Impact of Civil Wars on Guinea
These images show impact of civil wars in Liberia on neighboring
Guinea
• 2002: The light green color is the result of
deforestation in the “safe area” where refugees set
up camp
*The civil wars resulted in refugees creating camps in neighboring countries which
causes deforestation.

These images show deforestation rate in Cote
d’Ivoire, believed to be one of the highest in the
world
• 1988: Shows destruction of small forest fragments
• 2002: The lighter green strip bisecting the images
shows the result of extensive deforestation and intensive cultivation
Tai National Park, Côte d’Ivoire – site of world’s highest deforestation rate
*Intensive cultivation iscausing extensive
deforestation

What kind of effect do these have on the people of Africa (where they work, live, and
their transportation)?• Sahara – Historically a trade route– Work is trade or farming– Live near water supplies (scarce)– Rely upon camels for transport
• Sahel– People rely upon farming– Some areas are rich in natural resources– Live near water supplies (scarce)– Rely upon camels and waterways for transport– Many people live without running water, electricity, or proper sewers– Very susceptible to bad weather
• Savanna-Mostly farming-Wildlife parks/tourism-People gather near good farmland and water supplies (also a source of their jobs)-Roads and waterways for transport
• Rain Forest-farming, mining, & timber industry= major occupations-deforestation is taking place (cutting down trees so that there is more room for farming)-transportation can be difficult because of poorly maintained roads-people live where the jobs are
