Vegetation degradation in ENSO events: Drought assessment, soil use and vegetation evapotranspiration in the Western Brazilian Amazon

In recent years, the degradation of Amazon forest has been target studies at global level to identify elements and factors influencing this process. Thus, study had as objective vegetation during years El Niño Southern Oscillation (ENSO) phenomenon in State Amazonas. We used remote sensing data, typologies, weather from 14 conventional stations located Evapotranspiration images obtained MODIS Global Project (MOD16A2), data fire sources Terra Aqua collection (MOD146) platforms were used. The 6 different forms typologies found region also used, addition climatic maximum, minimum temperature, relative humidity, sunshine wind speed state station estimate reference evapotranspiration, using empirical methods Val-1, Val-2, Val-3, Val-4, Irmak-1, Irmak-2 Alex. results show differences correlations between evapotranspiration highest was Open Ombrophilous Forest. Fire foci concentrated Dense Forest areas. Standardised Precipitation-Evapotranspiration Index (SPEI) showed be an efficient index characterize drought events, besides showing agricultural expansion region. largest trends SPEI phenomenon. A better understanding ENSO effects on could prevent uncontrolled loss. Governance interventions involving national financial actors, well local populations, play a role this.
