Shaver Africa Geography and Environmental Issues

In sub-Saharan Africa, less than 50% of the population has access to safe drinking water because of environmental pollution. How has this shortage of safe drinking water most likely affected development in sub-Saharan Africa?

• It has slowed economic growth.

• It has increased the size of the Sahara.

• It has increased population growth.

• It has slowed deforestation of the rainforest.

What effect does poor soil and deforestation have on land in Africa?

• Land is excellent for archaeological dig sites.

• Land becomes useless for agriculture.

• Land becomes part of national park systems.

• Land becomes a better place to raise a family.

Which of the following pictures shows one of the results of allowing animals to over-graze the steppe regions of Africa?

• 
• 
• 
• 

In the Sahel, overgrazing and drought have resulted in a decrease in the steppe region and increase of the Sahara. What is this process called?

• Deforestation

• Desertification

• Unequal Distribution

• Environmental Pollution

Which of the following would be a result of fertilizer running off of fields near the Nile river?

• The Sahara desert would creep into the Sahel and cause deforestation there.

• The water would becomes extremely good for irrigation and for people to drink because of the extra nutrients.

• The Sahel would spread into the Sahara causing there to be less land available for grazing of animals in the Sahara.

• The water would become polluted and not use-able for drinking or irrigation.

Which of the following explains why the population of the Sahara is low?

• There is too much oil there.

• There is too much water there.

• There is a scarcity of oil there.

• There is limited access to water there.

Which of the following shows the area where most of Africa's commercial agriculture occurs?

• 
• 
• 
• 

In which of the following regions in Africa would you most likely find someone working in the logging industry?

• The Sahara

• The Sahel

• The Savannah

• The Tropical Rainforest

Where is farming possible in the Sahara?

• in the tropical rainforest areas

• near the Nile River and scattered oases

• in the large grassland areas

• near the southern tip of Africa

If African's living in the Sahel know that their nomadic and semi-nomadic herding lifestyles are causing desertification, why do they keep doing it?

• They need to feed their families and it is the only economic opportunity they have.

• They are more concerned with becoming wealthy than they are with protecting the environment.

• They farm land is so good in the Sahel that they get bored and look for something else to do.

• They believe spreading the desert will eventually result in more arable land in the region.
