             abstract = "Recent publications indicate that the Amazon may be acting more as 
                         a carbon source than a sink in some regions. Moreover, the Amazon 
                         is a source of moisture for other regions in the continent, and 
                         deforestation over the years may be reducing this function. In 
                         this work, we analyze the impacts of elevated CO2 (eCO2) and land 
                         use change (LUC) on gross primary productivity (GPP) and 
                         evaporation in the southern Amazon (7°S 14°S, 66°W 51°W), which 
                         suffered strong anthropogenic influence in the period of 
                         1981\‒2010. We ran four dynamic global vegetation models 
                         (DGVMs), isolating historical CO2, constant CO2, LUC, and 
                         potential natural vegetation scenarios with three climate variable 
                         data sets: precipitation, temperature, and shortwave radiation. We 
                         compared the outputs to five observational data sets obtained 
                         through eddy covariance, remote sensing, meteorological 
                         measurements, and machine learning. The results indicate that eCO2 
                         may have offset deforestation, with GPP increasing by 
                         \∼13.5% and 9.3% (dry and rainy seasons, respectively). 
                         After isolating the LUC effect, a reduction in evaporation of 
                         \∼4% and \∼1.2% (dry and rainy seasons, 
                         respectively) was observed. The analysis of forcings in subregions 
                         under strong anthropogenic impact revealed a reduction in 
                         precipitation of \∼15 and 30 mm, and a temperature rise of 
                         1°C and 0.6°C (dry and rainy seasons, respectively). Differences 
                         in the implementation of plant physiology and leaf area index in 
                         the DGVMs introduced some uncertainties in the interpretation of 
                         the results. Nevertheless, we consider that it was an important 
                         exercise given the relevance.",
