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: This study used the Budyko framework to explore the impact of precipitation and human activities on streamflow variability in the Lancang River Basin. The results showed that the four parametric Budyko equations performed better in reflecting changes in catchment characteristics, and longer baseline periods yielded more reasonable results in attributing streamflow change. The study also found that human activities dominated the streamflow decrease during the transition and impact periods, while climate change further exacerbated the streamflow decrease in LRB.

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 assesses changes in the importance of different hydrological drought generation processes in the European Alps. The findings show that the changes in drought processes are stronger in high-elevation catchments, where there are clear changes in drought seasonality. The study also suggests that changes in drought severity and generation processes are related, with snowmelt-deficit droughts having larger deficits than cold temperature-induced droughts.

Summary: Climate change intensification leads to changes in catchment properties, resulting in uncertainties in describing catchment hydrological behavior. This study explores the hydrological response to multiyear drought and identifies the causes behind it. The results show that multiyear drought mainly causes changes in the precipitation-streamflow relationship. The severity of drought, leaf area index, and slope play a role in determining the magnitude of these changes. Catchment properties can alleviate the reduction in streamflow, but they also have negative effects.

Summary: Climate change intensification can lead to unprecedented alterations in global hydrological cycling. This study used the Budyko framework to assess the impact of long-term drought on changes in streamflow and developed a novel method to analyze the effects of climate and catchment properties changes on streamflow. The results showed that long-term drought increases catchment property parameter, altering the partitioning of precipitation into evaporation and streamflow. The reduction in streamflow is primarily controlled by climate changes, with asymmetrical effects induced by catchment property changes. Understanding the hydrological response to multiyear drought events is important for comprehending the impact of climate change on water resources.

Summary: This study validates the performance of three different Budyko equations for the elasticity method in 22 basins in China. The empirical Budyko equation showed lower errors in simulating runoff changes compared to the analytical Budyko equations. The results reveal that in semi-humid environments, changes in basin characteristics are the main driver of runoff changes, while in humid basins, precipitation plays a larger role in the analytical Budyko-based methods and basin characteristics in the empirical Budyko-based method.

Summary: Vegetation and climate have significant impacts on the hydrological cycle, and understanding their effects on streamflow changes is crucial for water resource management. This study examined the influence of changes in vegetation composition and climate variability on streamflow changes in 3434 global watersheds from 2003 to 2016. The findings highlight the importance of considering changes in terrestrial water storage and reveal the varying sensitivity of streamflow changes to different factors in different regions. The research also sheds light on the dominant factors driving streamflow changes in different watersheds and the differing influences of vegetation composition in different climatic zones.

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: 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.
