Carbon Cycle and Forest Management
The Amazon's role in global carbon cycling demonstrates the relationship between water and carbon cycle a level geography concepts. The forest maintains high Net Primary Productivity (NPP) despite challenging soil conditions.
Definition: Net Primary Productivity (NPP) represents the net amount of carbon captured by plants through photosynthesis.
Highlight: The Amazon stores approximately 180 tonnes of carbon per hectare above ground and 40 tonnes per hectare in root systems.
Example: The REDD scheme with the Surui people exemplifies successful carbon credit trading by indigenous communities.
Conservation efforts include:
- Amazon Regional Protected Areas covering an area 20 times the size of Belgium
- Reforestation projects involving NGOs and businesses
- Carbon credit trading systems
- Indigenous people's participation in forest protection
The vegetation serves as the principal carbon store, holding approximately 100 billion tonnes of carbon, with 60% stored in above-ground biomass. The rapid decomposition cycle, facilitated by high humidity and temperature, maintains the ecosystem's productivity despite nutrient-poor soils.
