Theme 3 - Environmental Risks of Economic Developments Flashcards
1
Q
soil erosion
physical causes of soil erosion
A
- wind & water
- deforestation
- desertification
- climate change
2
Q
soil erosion
human causes of soil erosion
A
- overcultivation
- rising populations
- overgrazing
- soil compaction (trampling)
- groundwater abstraction
3
Q
soil erosion
ways to manage soil erosion / desertification
A
- microdosing fertilisers
- shelter areas of soil -> prevents rain washing away soil
- intercropping
- drip irrigation -> avoids waterlogging
4

9
Q
climate change
human causes of climate change
A
- carbon dioxide (burning solid matter)
- methane (farting ruminants)
- nitrous oxides (transportation)
10
Q

how does economic development cause climate change?
A
- deforestation
- industrialisation
- emissions
- melting permafrost layers
11
