Shrinking Lake Chad shared by Nigeria, Niger,
Chad and Cameroon
Persistent drought has shrunk Lake Chad to about
a tenth of its former size

• 1972 Larger lake surface area is visible in
  this image

• 2001 Impact of drought displays a shrunken
  lake, comparatively much smaller surface area
  than in 1972 image

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.

Tai National Park, Côte dIvoire site of
worlds highest deforestation rate
These images show deforestation rate in Cote
dIvoire, 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

Intensive cultivation is causing
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
