Forest

Question 1

Country Distribution

Answer 1

Russia 20%
Brazil 12%
Canada 8.5%
USA 7.6%
China 5.4%

Question 2

environmental impacts of deforestation

Answer 2

carbon storage
Modified climate (less CO2 absorbed by trees and increase of CO2 presence if trees are being burnt, plus extra Co2 in the atmosphere because of lack of trees)
Loss of biodiversity (species lose habitat therefore population loss) due to fragmentation (from roads - makes more vulnerable to droughts, fires, floods)
Loss of water cycling

Question 3

Social impacts of deforestation

Answer 3

diseases spread amongst indigenous population through contact with timber cutters
Increase in viral disease and malaria - ecological changes, less trees, leaves a dirt plain, turns muddy and into a pond, causes stagnant water
Increase in westernisation - contribution to the disappearance of ancient practices, e.g.supermarkets not forests, loss in spiritual significance and medicine

Question 4

Economic impacts of deforestation

Answer 4

Loss of subsistence agriculture
Increased commercial logging/ invasive and often aggressive
Timber being shipped out cheaply, money bypassing locals

Question 5

LGM

Answer 5

forest was 10%

Question 6

today

Answer 6

30%

Question 7

Distribution

Answer 7

75% of all forest is in high to middle income countries
45% of forest cover exists in tropical countries

Question 8

Drivers of deforestation

Answer 8

agriculture 73%
logging 19%
fuel wood collection 6%

Question 9

human factors increasing deforestation

Answer 9

infrastructure projects
- roads that lead through forests lead to high levels of fragmentation of forest

Question 10

Natural factors

Answer 10

pest invasions
climatic event
fires
HOWEVER forests usually recover from this but this has been increased by climatic change
