- Fragile Environments
- Soil erosion
- 3 main types
- Sheet
- Gully
- Wind
- Made worse by
- Overcutting+ clearing
- Overgrazing
- Overcultivating
- Compacting with heavy machinery
- Ploughing fields in the same direction as the slope
- Consequences
- Malnutrition+ illnesses
- Famine+ starvation
- Migration
- Management
- Planting
- Terracing+ contour ploughing
- Dams
- Lines of walls earth/ stons
- 3 main types
- Desertification
- less rainfall=> less vegetation cover=> more soil moisture
- More intense rainfall=> more run-off and less soil moisture
- Deforestation
- Causes
- Commercial logging
- Road building
- H.E.P.
- Land for peasants
- Agriculture
- Mining
- Consequences
- Loss of forest+ habitat
- Loss of habitat+ relocatioon of tribes
- Pollution+ more Greenhouse gases
- Loss of O2+ more CO2
- Soil erosion+ increased profit
- Increased economic growth
- Protection
- UNFF
- Promotes sustainable forest management
- CITES
- Protects rainforest ecosystems
- ITTA
- Protects rainforest ecosystems
- International pressure
- Greenpeace+ logger trackers
- UNFF
- Causes
- Climate change
- Natural Causes
- Orbit wobles
- Sun output changes
- Volcanoes
- Ocean current changes
- Human Causes
- Burning fossil fuels
- Gases from aerosols+ coolants
- Large crop areas+ agriculture change
- Deforestation
- Air pollution+ waste
- Animal manure+ artificial fertilisers
- Prevention
- Reducing use of fossil fuels
- Finding alternative energy sources
- Reducing deforestation+ increasing afforestation
- Develop Carbon capture technologies
- Consequences
- Rising sea levels
- More hazards
- Ecosystems change
- Health+ conflict
- Natural Causes
- Soil erosion
