Climate change will have different impacts in different regions of the planet. Mapping temperature and precipitation forecasts is essential for formulating specific adaptation measures for indigenous peoples. The study analyzed the spatial variation of climate change in 25 indigenous lands (TIs) in the state of Acre. The climate variables used were average air temperature and accumulated average annual precipitation. The assessment was based on historical climate data from 1970 to 2000 and future climate projections for 2041 to 2060, considering the SSP5-8.5 scenario, with data from WorldClim, version 2.1. Of the 25 TIs analyzed, Mamoadate will show the highest average temperature increase of 4.91°C, followed by Cabeceira do Rio Acre, with 4.86°C. On the other hand, Kampa do rio Amônia will record the smallest variation in average annual temperature, while the other TIs could vary between 4.80°C and 4.55°C. Mamoadate will show the greatest reduction in rainfall, with -333.66 mm, followed by Cabeceira do Rio Acre, with -284.24 mm.
