Amazon Rainforest and the Carbon Cycle

What is the Net Primary Productivity (NPP) of the Amazon Rainforest?

2500 g/m²/yr

What is the biomass range of the Amazon Rainforest?

400-700 tonnes/ha

How much carbon is stored above ground and in roots per hectare in the Amazon Rainforest?

180 t C/ha (above ground) + 40 t C/ha (roots)

What percentage of all ecosystem carbon is stored in biomass in the Amazon Rainforest?

60%

How much carbon do the soils of the Amazon Rainforest store per hectare?

90-200 t C/ha

What is the annual carbon absorption from photosynthesis in the Amazon Rainforest?

30.4 billion tonnes C/year

What is the decomposition rate of carbon in the Amazon Rainforest?

24.5 tonnes/ha

What is the net carbon sink capacity of the Amazon Rainforest?

0.3-1 Pg C/yr

What physical factors influence the carbon cycle in the Amazon Rainforest?

High temperatures, sunlight, and rainfall promote rapid photosynthesis and high NPP.

How much of the global terrestrial NPP does the Amazon Rainforest account for?

15-25%

What are the impacts of deforestation on the Amazon Rainforest's carbon cycle?

Deforestation from 2001-2014 resulted in 40 million ha lost, leading to increased methane and CO₂ emissions.

What is the effect of agriculture on soil carbon in the Amazon Rainforest?

Ploughing exposes soil, increasing runoff and nutrient loss, leading to gradual carbon loss from exposed soils.
