Extensive commercial logging, the use of wood for cooking and heating, and excessive clearing of land by subsistence farmers has led to __________________ in most areas of Sub-Saharan Africa.
erosion
deforestation
desertification
water pollution
Which is an effect of deforestation?
an increased number of animal species due to the land that has been cleared
a decrease in the number of floods since there are less trees to trap rainfall
an increased amount of soil erosion and poor soil quality due to a lack of roots and nutrients
a larger variety of agricultural products since there are less trees to take out nutrients in the soil
If population growth occurs in an area that depends on farming, what might be a direct result?
Mining for minerals in the area will decrease.
Air pollution from farm equipment will increase.
Deforestation will occur to clear land for additional farms.
The area will also see an increase in industrial productivity.
Based on the map, the areas of Sub-Saharan Africa that are MOST vulnerable to desertification are
in the center.
near the coasts.
close to deserts.
in the southern tip.
Overfarming and overgrazing farmlands have been a major influence in which destructive process?
deforestation
reforestation
desertification
income distribution
"It is very hard for me to farm here due to overgrazing and poor soil. My farm land is slowly becoming a desert." The quote is best describing which region?
Sahel
Tropical Rainforest
Savanna
Sahara
What is the main reason farming is unsuccessful in Africa?
Not enough space
Not enough sun
Not enough water
Not enough shovels
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.
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
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.
Why are droughts a problem for farmers in the Sahel?
The soil is of poor quality and dry conditions results in even fewer crops
The desert stops expanding when there is rain in the Sahel
People do not try to farm in the Sahel any more due to the increased rainfall
Why do some governments ignore industrial pollution of major rivers and waterways?
Most government officials do not recognize pollution as a problem
They want the industries to be profitable
Industries always have plans in place to clean up polluting wastes
Deforestation of the rainforest can lead to:
Increased Carbon Monoxide in the atmosphere
Increased Carbon Dioxide in the atmosphere
Flooding because the trees act as a wall between the Congo river and Sahel region
What destroyed the grassland and forests that were once found in the Sahel?
Years of heavy flooding
Continuous farming and over-grazing
The development of factories
Why is most rainforest area lost today?
harsh drought and high winds
diseases that attack old growth trees
logging for industry, farming, and fuel
Which is a result of desertification for the people living in the Sahel region?
decreased support from the United Nations
more jobs in manufacturing
increased starvation and poverty
