The present study aims to understand the climate vulnerability of small producers residing in the municipalities of Cachoeira do Arari, Salvaterra and Soure, located in the Marajó Archipelago, based on the analysis of the occurrence of climatic events in the region, and the projection of the climatic variables of interest in future scenarios. The current agroforestry practices adopted by the target population of the study were also evaluated, aiming to identify opportunities to adapt to the effects of climate change and to propose the use of agroforestry systems to increase the resilience of communities and the landscape
