AFRICA CURRENT PROBLEMS

1. Water Issues

2. Deforestation

3. Desertification

Page 2: #5 – In SE Asia, it was Industry & Population. In Africa, it is Human Activity or Natural Environment Pollution. #6 – Soil is not fertile for growing

WATER ISSUES1. Sub Saharan Africa (Africa below the Sahara) is lagging

behind the rest of the world in safe drinking water.

2. 58% of the 684 million people in S.S.A. have clean water. The average is 79% for the entire developing world.

3. S.S.A. has a 36% sanitation rate. Meaning a pit, bucket, or open field provides the best option for some.

4. Roughly 3,900 children in S.S.A. die each day, yes DAY, due to poor hygiene and dirty water. Most diseases are carried through dirty water & human excrement.

1. WATER ISSUES5. In SE Asia what contributed to the majority of

pollution? What contributes to Africa’s pollution?

6. How does the lack of water affect agriculture? What is the impact on S.S.A.’s economic growth?

#5 – In SE Asia, it was Industry & Population. In Africa, it is Human Activity or Natural Environment Pollution.

#6 – Soil is not fertile for growing crops. Agricultural industry suffers.

2. DEFORESTATION

Deforestation - the action or process of clearing of forests; also : the state of having been cleared of forests.

DEFORESTATION

1.REASONS FOR DEFORESTATION

A. More Agricultural LandB. Population GrowthC. More Space for HousingD. Trees Make a Profit!E. Heating & Cooking

DEFORESTATION2. WHAT’S WRONG WITH DEFORESTATION?

A. Soil Erosion – Soil exposed to sun. Nutrients are lost when rain washes away soil.

B. Water Cycle Disrupted – Water is drawn up through a tree’s roots. Makes climate dry in deforested areas.

C. Flooding & Drought – Forests are not there to absorb water. Drought occurs to the climate change from lack of forests.

3. DESERTIFICATION

Desertification - the process of becoming desert (as from land mismanagement or climate change).Source - http://www.merriam-webster.com/dictionary/desertification

Sahelian AfricaSahel: A semiarid region of north-

central Africa south of the Sahara Desert

WHERE DOES DESERTIFICATION OCCUR?

Background to the Sahel• The countries comprising this region

of Sub-Saharan Africa depend more on their natural resource base for economic and social needs than any other region in the world.

• Two-thirds of this region’s people live in rural areas and rely on agriculture and other natural resources for income.

SAHELIAN DESERTIFICATION

Desertification is when a desert gradually spreads to the surrounding areas of semi-desert. Why?......

Page 19: #5 – In SE Asia, it was Industry & Population. In Africa, it is Human Activity or Natural Environment Pollution. #6 – Soil is not fertile for growing

Why does the Sahel suffer from desertification?

DESERTIFICATION

Increase in population Increase in cattle

Deforestation for fire wood

Grassland grazed more intensively

Roots no longer hold soil together Roots may be eaten as well as grass

Leaves no longer protect soil from weatherLess vegetation means less protection from weather

Loose top soil blown away by wind -Soil Erosion
