- Desertification in the Sahel
- Location
- It covers Mali and Niger
- It covers 1/5 of Africa
- It touches the Southern border of the Sahara desert
- Causes
- Low, unreliable rainfall
- Due to geographical location: landlocked and by the equator
- Poor farming techniques
- The land isn't allowed to rest so nutrients aren't reintroduced into the soil
- Overgrazing
- Overcultivation
- War: it damages the soil
- Deforestation
- A lack of evapo-transpiration
- Climate change
- Global warming
- Low, unreliable rainfall
- Consequence
- 24000 have died of starvation
- As farmers can't produce big enough yields of crops
- Mass migration
- Duststorms, pollution and poor quality water
- Poor biodiversity
- $42 billion has been lost
- Political instability and war
- The locals have to rely on aid from the UN
- 24000 have died of starvation
- Prevention
- Planting perennial plants
- Stone lines
- Green belts
- GM crops
- They can withstand the desert condiitons
- Agro forestry
- Results
- Desertification has stopped
- Biodiversity has decreased
- It has boosted the economy
