The Amazon Rainforest case study
General background info
Area of 6 million km2
70% of it contained in Brazil - link to Bolsonaro and the pique of 362pp for carbon released in Feb of this year
Average annual temp - 25-30 degrees Celsius
Precipitation - approx 2000mm
50/60% rainwater recycled through evapotranspiration
Carbon cycle
2.4 billion tonnes stored in rainforest, 1.7 billion tonnes of carbon released
2500 grams/m2/year
Human factors affecting carbon cycle
Biomass of trees = 60% of all carbon

Human factors affecting water cycle
Deforestation
17500 km2/year between 1970 and 2013
Between 2000-2012, 30,000km2 of Bolivian rainforest was removed for cattle ranching
2014, Upper Madeira flood
60 killed
68,000 families
Cholera and leptospirosis
Half of all rainfall runs off into rivers, increasing river discharge and risk of flooding when forests are converted into grasslands
Strategies to improve
Brazil committed to restoring 120,000 km2 by 2030
Shifting cultivators
Reforestation
Protection through legislation
Improving agricultural techniques
