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 ?
