Global Management Strategies

Question 1

Wetland restoration

Answer 1

Occupies 6% of Earth’s land surface but stores 35% of terrestrial carbon
Canada’s prairie provinces lost 70% of wetlands

International convention on Wetlands- up to 500 ha of grade 1 farmland in E. Cambridgeshire being converted to wetland

Question 2

Afforestation

Answer 2

Reduces atmospheric carbon because trees are carbon sinks

China aims to afforest 400 000 km2 (size of Spain) by 2050. Also helps to prevent desertification and land degredation.
Achieved 30 000 km2 in 2000-2009

Question 3

Agricultural practices examples and solution

Answer 3

Overcultivisation results in soil erosion and the release of carbon.
Intensive livestock farming produces 100 million tonnes/yr of CH4

Manure management can reduce CH4 emissions by storing manure in anaerobic containers

Question 4

International agreements. Examples? Why did some opt out?

Answer 4

Some of the World’s largest greenhouse emitters opted out of these agreements

Kyoto agreement put ACs in legally binding commitments to reduce emissions which EDCs were exempt despite being some of the largest emitters
