Water & Carbon Cycles
-
Carbon Cycle
Atmospheric Cycle
-
-
CO2 is relatively unreactive and and usually removed from atmosphere through interactions with the terrestrial and oceanic carbon cycles
Oceanic Cycle
-
Primary inputs and outputs are by gas exchange with the atmosphere but also a significant input of both organic carbon and carbonate ions from continental runoff
-
Carbon flux within oceans is controlled by physical, chemical, and biological processes
Terrestrial Cycle
Carbon is cycled relatively rapidly between soil and vegetation and the atmosphere. "Fast carbon cycle"
Occurs within ecosystems, which are now almost all subject to intensive human impacts
Uptake of CO2 from atmosphere by plant photosynthesis. CO2 released back into atmosphere due to respiration of plants and animals

Indonesia Case Study
Deforestation
Palm Oil Industry
Set to increase, therefore deforestation will continue

-
Impacts on carbon cycle
-
-
Resulting in global warming, ice melt, and sea level rise
Peat soils act as a carbon sink but upon exposure to air due to deforestation, they will release CO2 and can no longer act as a carbon store
-
Impact on water cycle
Breaks the water cycle, reduction of rainfall so area becomes drier.
Drier conditions can increase the risk of forest fires, which release even more CO2 into atmosphere (positive feedback loop)
Surface flow is more rapid -----> ground becomes drier and more rapid soil erosion. Hard to grow crops, so animals and people will struggle to find food
