Dynamics of Variation in Agricultural and Forest Areas in the Southwest Amazon (Sena Madureira, AC)

Abstract

Objective: To analyze the dynamics of variation in agricultural areas in the southwest of the Brazilian Amazon, specifically in the municipality of Sena Madureira, Acre.   Theoretical framework: The expansion of agriculture in the Brazilian Amazon is the result of new logistics associated with new flow modes that allow the insertion of their activities in areas with potential for use and occupation.   Method: Use of geotechnologies to analyze the dynamics of variation in areas and forms of use and occupation of agriculture, based on data generated by MapBiomas, with the aid of the ArcGis 10.8 software. Use of linear regression, including coefficient of determination and bivariate analysis.   Results and conclusion: Exponential growth of cattle ranching with grassland areas reaching 222,413 hectares in 2022, expanding preferentially both in the vicinity of the margins of the BR 364 and AC 339 highways and in the urban perimeter of Sena Madureira, while agriculture presented oscillatory amounts in hectares of area, suggesting its use for subsistence. The very strong relationship between forest and grassland variables with linear regression analysis, shows the growth of agricultural areas to the detriment of forest areas. The study made it possible to generate bases for understanding the lack of conciliation between economic growth and environmental preservation.   Implications of the research: Generation of bases for understanding the relationship between agricultural economic growth and environmental preservation in the southwest of the Brazilian Amazon.   Originality/value: The historical perspective concerning the comprehension of areas used for agricultural practices and the intersection with Amazonian environmental issues.
