Summary: This study developed a simple analytical model to explain the asynchrony between water supply and demand globally. The research demonstrated that this asynchrony can explain the spatio-temporal variability of water availability, and water budgets are widely responsive to changes in climate asynchrony.

Summary: This research investigated the contributions of climate and human-induced change to streamflow alteration in four catchments in southern Romania. The results showed that there were breakpoints in streamflow between 1981 and 1985, followed by a decrease in average annual streamflow. Climate change was found to be the main driver for most of the streamflow decline.

Summary: This study proposes a three-stage precipitation partitioning framework to investigate the climate controls on mean annual groundwater evapotranspiration (GWET) in west-central Florida. The Integrated Hydrologic Model is used to simulate daily GWET, total evapotranspiration (ET), groundwater recharge, base flow, and total runoff. The results show that the ratios of GWET to various water variables decrease exponentially with watershed aridity index (WAI). The contribution of GWET to the ratio between total ET and available water or watershed wetting decreases with WAI in both one-stage and two-stage precipitation partitioning frameworks. Climate variability at different temporal scales affects GWET differently, with intra-monthly variability having the highest impact. Finally, the percentage of forest and wetland and impervious land cover contribute to the ratio of GWET to available water for GWET.

Summary: This study uses the Budyko framework and the decomposition method to associate the flow variability dynamics in the Sao Francisco River catchment with climatic and anthropic covariates. The results show that streamflow decreased in the upper, middle, and lower portions of the catchment by 183 mm, 56 mm, and 26 mm, respectively. Climate change is the main factor in upstream areas (75%, 43%, and 42%), while human activities have a more pronounced influence in downstream areas (27%, 57%, and 58%). However, as the drainage areas increase, the model performance deteriorates, introducing higher levels of bias and uncertainty to the attribution results.

Summary: This study quantified the hydrological impacts of climate and anthropogenic changes in the Upper Grande River Basin and predicted potential future impacts on runoff based on climate model projections. The results showed that both climate and land-use changes have significant influences on the hydrological regime, with the expansion of agricultural areas being the main driver of anthropogenic impacts. Future climate projections indicate a reduction in average runoff, and the Budyko framework performed well in predicting future climate change impacts on water availability, similar to previous hydrological modeling studies in the same region.

Summary: The changes in climate and catchment properties have significantly altered the hydrological processes at different scales. This study derived new formulas for the unsteady-state streamflow elasticity in a modified Budyko framework, considering both storage change and catchment properties. The study found that the estimated elasticity coefficients performed well in simulating annual streamflow, and the variability of unsteady-state elasticity was higher than that of steady-state elasticity.

Summary: The sensitivity of streamflow to climate change and permafrost thawing in Siberia remains not well understood. Using the Budyko framework and superposition principles, researchers found that the streamflow of the Ob, Yenisei, and Lena rivers have increased over the past 84 years, with precipitation induced by warming climate being a major contributing factor. However, winter streamflow is particularly sensitive to temperature, with rising temperatures potentially increasing groundwater discharge due to permafrost thawing.

Summary: This study evaluates the performance of nine global ET products in estimating ET under extreme climatic conditions, and finds that the estimation accuracy of all products is significantly reduced in extreme conditions, with the most severe impact in the Americas region. Multi-source data fusion products show the best estimation performance, while GLEAM_v3.6b performs the best among remote sensing modeling products and MOD16A2 performs the worst. Land surface reanalysis products are most affected by extreme conditions, with ERA5 having the largest errors. ET products show significant error fluctuations and overestimation in most of North America and in arid and semi-arid regions.

Summary: This study predicts future streamflow changes in 889 watersheds in the contiguous United States based on projected climate and land use changes. The results show that the random forest model can explain over 85% of the variance in most watersheds. The study also found that relative cumulative moisture surplus, forest coverage, crop land, and urban land are the most important variables affecting the time-varying omega.

Summary: The retreat of glaciers has changed hydrological processes in cryospheric regions and has a significant impact on water resources at the basin scale. This study focused on the upper reach of the Shule River Basin as a typical cryospheric-dominated watershed and applied an extended Budyko framework to investigate the sensitivity and contribution of environmental changes to evapotranspiration (ET) variation. The findings showed that precipitation was the most sensitive factor, followed by the controlling parameter (w), and glacial change also had a clear impact on ET change.

Summary: Increased atmospheric evaporative demand has important implications for water-scarce lands. This study assesses recent trends in annual reference evapotranspiration (ETo) and its drivers in the continental United States. Results show large changes in ETo, with temperature being the main driver. Increases in ETo are mitigated by increases in specific humidity in non-water-limited regions, while decreases in specific humidity and increases in wind speed and solar radiation amplify ETo increases in the West.

Summary: Afforestation has a significant impact on global and regional climate, but its specific effects on local temperature in temperate regions have been unclear. This study used simulations and satellite observations to investigate the temperature effect of large-scale afforestation in the Loess Plateau in China. The results showed that afforestation caused a warming effect on the 2-meter air temperature at the inter-annual scale, with a cooling effect in July and August and a warming effect in other months. The radiative effect was found to be the dominant factor in the local temperature change induced by afforestation.

Summary: Revegetation in China's Loess Plateau has led to an increase in surface water yield, despite the enhanced evapotranspiration. This is mainly due to the increase in regional precipitation that outweighs the increase in evapotranspiration. Enhanced land-atmosphere interactions following revegetation have accelerated local moisture recycling and contributed to the increased precipitation. Previous assessments that ignore vegetation-climate feedbacks may have overestimated the threats of revegetation on dryland water resources.

Summary: Accurate modeling of vegetation dynamics is crucial for understanding and predicting the impacts of vegetation changes on terrestrial water-energy-carbon cycles. Parameter optimization and data assimilation can significantly improve the performance of dynamic vegetation modules in land surface models. Combining these methods can compensate for their limitations and lead to better simulation of water and carbon cycle processes.

Summary: Afforestation is an effective method to control soil erosion, but it consumes water resources and has feedback effects on local precipitation. The world's largest afforestation program in China has increased precipitation and strengthened the atmospheric water cycle on the Loess Plateau. Afforestation has created a more humid atmosphere, enhanced the soil moisture-vegetation-precipitation feedback, and favored precipitation generation.

Summary: Recent climate change and human activities have caused significant changes in streamflow in the middle reaches of the Yellow River basin (MRYRB). This study analyzed the contributions of both natural and human factors to streamflow changes at the annual and seasonal scale. Results showed that streamflow declined after years of abrupt change, and the effects of human activities and changes in soil water storage played important roles at different scales. Human water use, particularly for domestic purposes, electricity generation, and manufacturing, was the primary factor affecting streamflow reduction in certain sections. Vegetation restoration and check-dam construction also had significant impacts in specific sections.

Summary: Large-scale anthropogenic revegetation in non-humid regions increases water consumption and may lead to water imbalance. This study evaluates the upper limit of vegetation coverage supported by rainwater resources and compares the carbon sequestration capacity and efficiency under different restoration scenarios. The results show that the maximum vegetation scenario has higher LAI and gross primary productivity than the actual scenario.
