Abstract Quantifying and distinguishing the contributions of climate change, elevated atmospheric CO2 concentration (eCO2) and human activities to evapotranspiration (ET) and gross primary production (GPP) changes is of great significance for assessment of water shortage and land degradation. Based on the Vegetation Interface Processes (VIP) model, the spatial-temporal changes of ET and GPP in the Three-North Region (TNR) of China from 1982 to 2017 were estimated. The results showed that annual ET and GPP increased slightly with a rate of 0.71 mm yr−1 (P
