                         cover, such as pasture and agriculture, in Amazonia, affects 
                         regional carbon and water balances, significantly contributing to 
                         increased carbon emissions and reduced evapotranspiration. 
                         However, secondary forest (SF) growth, resulting from the 
                         abandonment of low-productivity pasture areas, offers a potential 
                         alternative to counterbalance the effects of deforestation on 
                         carbon release to the atmosphere and evapotranspiration reduction. 
                         In this work, we present four years of eddy flux measurements of a 
                         SF that is approximately 20 years old, located in Central 
                         Amazonia, and we compare these measurements with those of a PF in 
                         the same region, analyzing daily and seasonal variations in 
                         evapotranspiration, gross primary productivity of carbon and water 
                         use efficiency. On average, evapotranspiration is 20% higher in 
                         the SF (3.6 mm day\−1) than in the PF (3.1 mm 
                         day\−1), while gross primary productivity is only 5% higher 
                         in the SF (8.1 gC m\−2 day\−1) than in the PF (7.8 
                         gC m\−2 day\−1). Despite robust evidence of higher 
                         evapotranspiration and gross primary productivity in SF, the 
                         estimated uncertainty range of WUE is large to reach definite 
                         conclusions about the differences on carbon gain per water loss 
                         between the sites. Nonetheless, the significantly higher 
                         evapotranspiration and gross primary productivity of SF may 
                         counterbalance both water and C losses from deforestation and has 
                         important implications for regional budgets.",
