Résumé
The transformation of the forest into pastures in the Brazilian Amazon leads to significatives climatic consequences at a local scale. This paper proposes to compare the temperatures observed between 2002 and 2006 using local measurements in the area of Alta Floresta (Mato Grosso, Brazil) between a cleared sector and a forested one located in a reserve. The cleared sector always appeared hotter and drier (from 5 to 10%) than the forested area. This variation was especially marked during the day when it reached on average about 2°C but also seemed to increase during the night with the arrival of the dry season (+0,5°C).
