Note générale : |
The following hypothesis is presented and deffended : climate is a predisposing factor, not a determinig factor. Climate, characterised as it is in many parts of the Amazon basin by a distinctive dry season of up to seven months in length, as in the Rupununi Rio Branco region, often makes the presence of tropical rain forest problematical and predisposes the environment towards the development of savanna vegetation. Low soil fertility and laterite are frequently considered as features associated with savanna handscapes, especially on senile pediplaned surfaces. Occasionally they may be resultants factors, as when the nutrient cycle is broken after the disappearance of forest cover... |
