- Abstract
The Pampean Region has strong comparative advantages for agricultural production. Current production models include annual double cultivation with increased use of agrochemicals and strong alteration of ecosystems with biodiversity fragmentation. The aim of this work is to temporarily analyze the transformations of the ecosystem services (SE) of the agroecological units (UAE) of the Quequén Grande River Basin (CrQG). The methodology is based on the estimation of sustainability indicators: soil and water quality conservation (CCSA), biodiversity conservation (CB) and ecosystem conservation (CE). For these, surface data obtained from classified images on the advancement of agricultural development by UAE of the Basin and field data obtained in interviews and background studies are necessary. The results show that the agricultural instensification process was manifested with different intensity in the different UAE of the Basin, the Sierras and Serranías unit was the most affected in both periods, with high values of environmental risk. The conclusions are that SE are affected differently in the CrQG and therefore it is intended to contribute to the territorial planning of SE in the basin.
