The results showed a reduction of 230.3 hectares in the area corresponding to the wetland from the beginning to the end of the study period during the periods of least precipitation. The area cultivated especially of sugarcane, showed a significant increase, which shows that there is a particular interest to extend mainly the agricultural frontier, while the livestock would have extended a smaller proportion, both processes subtracting important areas to the land of the wetland.
