“…Apart from long-term changes observed globally, the strongly regional and temporal differentiation of ET trends are evidenced, as proven for central Europe and central North America [11], and for the north-eastern United States [12]. For the period 1980-2010, largescale increases in ET were observed in south-eastern China, while decreases in ET occurred over the north-east [13]. Other studies conducted over the 71-year period from 1948 to 2018 confirmed that ET exhibited an increasing trend over almost 90% of the territory of China [14].…”

Given the importance of terrestrial evaporation (ET) for the water cycle, a fundamental understanding of the water quantity involved in this process is required. As recent observations reveal a widespread ET intensification across the world, it is important to evaluate regional ET variability. The specific objectives of this study are the following: (1) to assess annual and monthly ET trends across Poland, and (2) to reveal seasons and regions with significant ET changes. This study uses the ET estimates acquired from the Global Land Evaporation Amsterdam Model (GLEAM) dataset allowing for multi-year analysis (1980–2020). The Mann–Kendall test and the Sen’s slope were applied to estimate the significance and magnitude of the trends. The results show that a rising temperature, along with small precipitation increase, led to the accelerated ET of 1.36 mm/y. This was revealed by increased transpiration and interception loss not compensated by a decrease in bare soil evaporation and sublimation. The wide-spread higher water consumption especially occurred during the summer months of June, July, and August. Comparing the two subperiods of 1980–2020, it was found that in 2007–2020, the annual ET increased by 7% compared to the reference period of 1980–2006. These results can serve as an important reference for formulating a water resources management strategy in Poland.

“…According to the findings revealed by previous studies, the regional ET is driven essentially by climatic variables (Gao et al 2007;Cui et al 2020;Xie et al 2021). For example, Li et al (2021aLi et al ( , 2021b indicated that precipitation was the most important factor controlling ET changes over the entire water-limited regions in China. Soni & Syed (2021) indicated that precipitation was responsible for more than 65% of the ET changes observed in the Ganga River basins based on a Hierarchical Partitioning Analysis (HPA).…”

Evapotranspiration is an essential element of the hydrological process. This study derived the long-term series of evapotranspiration from 1982 to 2014 over the three basins, namely source regions of the Yangtze River (SRYR), the Huang River (SRHR) and the Lancang River (SRLR) in the Three-River Source Region of China by integrating multiple sources of evapotranspiration estimates based on the Bayesian model averaging approach, which made full use of the strengths of land surface models and satellite-based products to constrain uncertainties. Then, we analyzed the influences of climate change on evapotranspiration based on the partial least squares regression model. Results indicate that (1) the agreement between various evapotranspiration products and water balance-derived evapotranspiration estimates varies from region to region in the Three-River Source Region of China; (2) annual evapotranspiration increases in the SRYR (3.3±0.8 mm/yr) and the SRHR (0.8±0.4 mm/yr), whereas no significant trends are observed in the SRLR during 1982–2014; (3) annual evapotranspiration is found most sensitive to precipitation and temperature in the SRYR and the SRHR, while it is dominated by relative humidity and temperature in the SRLR during 1982–2014. Our results have important implications for understanding evapotranspiration variability and future water security in the context of global climate change.
