Disasters have intensified over the years and society's competence to manage them will require commitment and creativity. Ecosystem degradation is already one of the main causes of hydro-meteorological disasters, which requires an in-depth study of the circumstances in which they occur and their impacts to support the preparation, mitigation, response and recovery to disasters. In the study of a disaster that occurred in S��o Francisco Xavier in the state of S��o Paulo, this work investigated whether an authorized exploration of old Pinus sp., inserted in a native forest fragment in Permanent Preservation Areas (APP) of springs and water courses, was responsible for the interruption of the water supply of the entire district. Therefore, a documental survey was carried out on the event that took place in 2008; the vegetation in the hydrographic microbasin and the forest suppression area were mapped; and, the base data at the time were analyzed, as well as the water quality data at the point of abstraction of the Water Treatment Station (ETA) of S��o Francisco Xavier. The analyzes undertaken showed that the exploitation of pine trees was responsible for the turbidity of the waters of the Ribeir��o das Couves that triggered the disaster. |
