Main questions
3
1. Which is the Carbon balance
of the Amazon basin ?
(a) How do natural vegetation,
rivers and other processes
contribute to local and
regional C balance ?
2. How can land use change alter
the hydrological cycle and
river discharge ?
(a) Do reforestation helps to
control floods and minimum
river flows?
(b) Do crops, reforestation and
pastureland help to change
regional evapotranspiration ?
