Variabilité hydrologique et vulnérabilité des populations du Lago Janauaca (Amazonas, Brésil)

Closely related to the seasonal flood pulse of the Amazon River, the activities of várzeas farmers and fishermen are particularly sensitive to the critical events of hydrological variability. This paper analyzes the vulnerability of riverine communities to extreme high and low waters around the Lago...
