Climate Change is the cause:
Temperature increase
Irregular seasons
Unsustainable practises
Contributors of climate change
Other causes
Human *
Dam building?
Cultural factors e.g. size of flock determine status
Population density & increase
Land management
Cultural factors
Physical
Salinization
Soil erosion
Wind erosion
Reduced precipitation
Plan of report
What effect does desertification have?
War
Food insecurity
Poverty
Reduced biodivresity
Drought
1) what is desertification?
Where does it occur the most?
IPCC definition
Using statistics from UN
2) Physical causes
wind erosion
precipitation
rising temperatures
3) Climate change as a cause?
C02 levels increase (good or bad for soils?)
Temperature rise and intensity
Irregular climatic events
Does the rate of desertification correlate with rate of climate change?
Yes
How much does it correlate?
Is it the only cause?
No
Which other causes are involved?
What is the most important cause?
Solutions to desertification
If climate change is reduced/will desertification be reduced also?
Sustainability within agriculture etc.
4) Human causes *
Agriculture
Over-irrigation
Deforestation
Overcultivation
Cash cropping
Overgrazing/goat farming
Subsistence farming
Will 'fixing' climate change 'fix' these issues also?
