The process of making the desert bigger
What is One Source of water pollution in Africa?
Human Sewage or Agricultural Runoff
How does deforestation cause poor soil quality?
The nutrient rich soil erodes away
What climate change can accelerate deforestation?
Drought dries out the land and makes the process speed up
How does water pollution affect drinking water access?
People die from disease, crops are killed, people travel to find clean water
What is causing deforestation?
Agriculture in Sahel/Savanna and Logging in the Rainforest
How does desertification affect the people?
Makes it the Unequal Access to Water even greater, makes food more scarce
What group has the most access to clean water?
Agricultural Community

The ash is only good for one farming season and all of the nutrients are gone so trees cannot grow in that area
How does Deforestation lead to Desertification?
The mass cutting down of trees loosens the soil, the nutrient rich soil erodes away, the land that is left is dried out and only the desert remains
What do people do in the Sahara to find access to water (outside of living by the Nile)
Nomads travel from Oasis to Oasis
What is the connection between deforestation and food security?
The ruined soil doesn't allow farmers to consistently farm in one area so the community cannot be sustained
What are the long term effects of desertification?
Less land for farming, less land for water and rainfall, less land for the plants and animals to thrive, less land for communities to be formed, etc...
