| Sumario: | Abstract: Hydraulic fracturing, or fracking, has been widely implemented in several hydrocarbon-producing countries in Latin America for more than a decade despite being a highly controversial technique. Among multiple environmental impacts associated with fracking, the land cover/use change and space use competition have been scarcely studied. This article analyzes the spatio-temporal dynamics of land cover/land use changes in Burgos, Mexico, and Neuquén, Argentina basins. For this, ten representative oil fields from both hydrocarbon basins were selected. The study comprises a spatial and temporal analysis based on the use of Landsat images of three temporalities, a period ex-ante to the implementation of hydraulic fracturing (2002), the period of most significant expansion (2013), and an ex-post period (2019). There is a record of 7,570 wells in the Burgos basin, of which 2,153 can be classified as unconventional. In the Neuquén basin, of the 28,238 existing wells, 1,501 are unconventional. In the peak fracking period, native vegetation registered a decrease of 48% in the Burgos basin and 25% in the Neuquén basin. In Mexico, the most significant changes occurred in the Culebra field and the Fernández Oro Station field in the southern country. In both basins, in addition to the loss of native vegetation directly associated with fracking implementation, a decrease was found in areas dedicated to primary activities. This situation has led to territorial tensions due to the incompatibility of land uses and the unequal appropriation of space. |
