Resumo
This study evaluates land-cover changes in Vale do Acre, Brazil, with emphasis on forest-to-pastureconversion in the Chico Mendes and Cazumbá-Iracema Extractive Reserves. This is a quantitativeand exploratory study based on geospatial analysis, integrating multitemporal deforestation data(PRODES/INPE), livestock and non-timber forest product (NTFP) statistics (IBGE), and atmosphericmethane concentrations (Sentinel-5P/ESA). Data were processed using Geographic InformationSystems (GIS) and Python scripts to detect spatial and temporal trends in environmentaltransformations. Results show deforestation peaks in the Chico Mendes Reserve in 2019 (79 km²)and 2021 (90 km²), mainly in municipalities like Epitaciolândia near highways and urban zones. InCazumbá-Iracema, deforestation was highest shortly after its establishment, resurging from 2018onwards. The analysis indicates that cattle ranching expansion and declining NTFP production—especially rubber—are weakening traditional livelihoods in extractive communities. Additionally,pasture expansion correlates with rising atmospheric methane concentrations, particularly inmunicipalities where pasture areas have overtaken forest cover. These findings highlight the needfor public policies focused on sustainable land management, strengthened conservation efforts, andthe inclusion of traditional knowledge. The study contributes to the debate on regional developmentand socio-environmental challenges in the Amazon, emphasizing the role of extractive reserves inbalancing conservation and livelihoods.
