Summary: This study evaluates the impacts of climate change and human activities on the Ganges and Godavari river basins in India. The findings show that human activities have had a stronger impact on river discharge than climate change, especially in the pre-monsoon season. However, in the near future, climate change is projected to have a greater effect on streamflow, with the post-monsoon season being most affected for the Ganges and the pre-monsoon season being most affected for the Godavari. Uncertainty in streamflow estimates is higher for the Godavari basin. The results contribute to our understanding of natural and human-induced flow regimes in these river basins, which can inform future strategies for river management.

Summary: Earth system models have been widely used to simulate global terrestrial carbon fluxes, including gross primary production (GPP) and net primary production (NPP). This study evaluated the model performance of 22 ESMs participating in the CMIP5 and CMIP6 projects, finding that the multi-model ensembles (MME) outperformed individual models in simulating GPP and NPP. Despite improvements in CMIP6 compared to CMIP5, there is still much work needed to enhance the performance of individual ESMs and the overall CMIP. Future work should focus on more comprehensive model mechanisms and higher resolution coupling of land surface and atmospheric/oceanic schemes.

Summary: Future changes in the atmospheric energy cycle were estimated using climate models. The results show that with high emissions, there will be significant increases in available potential energy and kinetic energy in the winter season in both hemispheres. However, wave energy will decrease in the Northern Hemisphere winter and slightly increase in the Southern Hemisphere winter. Global warming will reduce certain energy conversions associated with wave-mean flow interactions, but increase energy generation associated with diabatic heating processes.

Summary: This study compares different approaches for long-term flood projection in diverse basins across the United States and finds that the precipitation informed approach is more accurate for regional change projections, while the hydrologic simulation approach is more informative for the direction of change in a single basin. When forced with GCM outputs, the precipitation informed approach outperforms hydrologic simulation in accuracy and precision, while hydrologic simulation may introduce biases in certain regions. Continued improvement in flood projection methods and the incorporation of uncertainty are highlighted as important future considerations.

Summary: The study predicts that under global warming, there will be a decline in snow water equivalent in large river basins of northwestern North America, with more severe declines in southern regions and the possibility of small increases or decreases in northern regions. The findings suggest that temperature and precipitation play a significant role in these changes, and that southern basins with high water demands are likely to experience the most extreme occurrences of snow drought.

Summary: Climate variability and underlying surface changes are strongly associated with runoff alterations in the Yarlung Zangbo River Basin. The increase in runoff in the upper region is dominated by changes in the underlying surface and glacier runoff, while the middle and lower regions are mainly attributed to the increase in precipitation. The findings have important implications for water resource security and sustainable development in alpine regions.

Summary: Water scarcity has become a prevalent issue in many regions over the past decades. Previous assessments largely overlooked the role of green water in supporting crop production. This study proposes an agricultural water scarcity index (WSIAW) that combines green and blue water to measure water scarcity. The results show that the WSIAW provides a better understanding of water scarcity compared to blue water assessments alone, and reveals an increasing severity of water scarcity in major agricultural regions, mainly due to expanding cropland and competing water withdrawals. The proposed WSIAW is important for addressing global water scarcity issues.

Summary: Water scarcity is a growing concern worldwide, with research patterns and focus varying across different countries. The number of publications on water scarcity is primarily influenced by gross domestic product (GDP) and population, and research is biased towards populated and affluent countries. Other factors such as physical water scarcity, research and development expenditure, and governance indicators also impact water scarcity research. Hotspots of research domains on causes, approaches, types, and effects of water scarcity differ among continents. Enhancing research in developing countries facing physical and economic water scarcity is crucial for improving adaptive capacity and reducing vulnerability.

Summary: This study examines the applicability of the Reformulated Gash Analytical Model (RGAM) for estimating rainfall interception (I) in reforested areas across the Hyrcanian temperate forests in northern Iran. The results show that different tree species have an impact on rainfall interception. The Norway spruce is the most effective species in reducing erosion and surface runoff. Average-based calculations indicate that evergreen needle-leaved forests have lower free throughfall coefficient but higher canopy storage capacity and evaporation rate compared to deciduous broad-leaved forests. The RGAM satisfactorily estimates I for all species except for the Acer velutinum stand.

Summary: Study in the northern part of China has shown that the trend of water scarcity has changed from positive to negative after 2001. While increased water withdrawal was the main factor exacerbating water scarcity before 2001, climate change, with its increased precipitation, has become the major contributor to alleviating water scarcity from 2001 to 2020. Future projections also indicate that climate change will further alleviate water scarcity in the region by increasing water availability. These findings highlight the growing significance of climate change in influencing water scarcity and have important implications for regional water policy-making.

Summary: Nepal, a mountainous country, has a complex climatic pattern ranging from tropical in the south to arctic in the north. The rise in temperature in the mountainous regions has attracted scientific interest, but there is a lack of data on the recent warming trends in different regions of Nepal and its ecological and societal implications. This study analyzed temperature data from 76 meteorological stations across the country to detect the warming trend and its impacts. The eastern part of the country experienced higher warming than the central and western parts, and all physiographic regions showed increasing temperature trends. Lower elevations in the mountainous regions experienced higher warming than higher elevations. Winter season had a higher warming trend except in the Terai region. The ecological impacts were found to be higher in regions with higher warming trends.
