Summary: In this study, a three-dimensional SEAWAT model was developed to simulate the impact of climate change and anthropogenic activities on seawater intrusion in the coastal region of Benin. The model was calibrated and validated using groundwater head and salt concentration data from 30 wells. The simulation results indicated a decline in freshwater head and an increase in the seawater intrusion area from 2015 to 2020. The model was also used to predict future changes in groundwater level and seawater intrusion area by the end of 2050, considering sea level rise and groundwater pumping rate. Additionally, the study analyzed the interface between fresh and saltwater using the SHARP interface and evaluated the effectiveness of a managed aquifer recharge system in reducing seawater intrusion rate.

Summary: Drained, lowland agricultural peatlands are significant sources of greenhouse gas (GHG) emissions, and reducing drainage depths is crucial for responsible management. Wetland agriculture strategies are needed to balance GHG mitigation with productivity in peatlands and compromise systems may help deliver partial reductions in emission rates. Successful implementation of these strategies requires participatory research approaches and cooperation among stakeholders.

Summary: This study reviews the interactions between permafrost and groundwater, with a focus on recharge and discharge in the Arctic and the Qinghai-Tibet Plateau. It found that the geochemical composition of groundwater is site-specific and varies within aquifers, reflecting water-rock interactions. The study also observed that permafrost thaw increases groundwater discharge on land, and climate warming is likely to accelerate permafrost degradation and enhance hydrological connectivity. With regards to submarine groundwater discharge, the impact of permafrost thaw can either reinforce or reduce it, depending on the changes in aquifer pressure. The study highlights the need for long-term interdisciplinary in situ measurements for accurate predictions of groundwater flow and permafrost dynamics in a warmer climate.

Summary: There is currently disagreement over whether the high-latitude region is a source or sink of carbon due to system complexity and data limitations. Recent advances in machine learning algorithms have been popularized for upscaling site measurements of ecosystem processes and forecasting their response to climate change. However, these predictions are almost never validated with independent datasets due to data limitations.

Summary: A series of experiments were conducted to compare the impacts of different land surface model parameterization schemes, meteorological forcing, and land surface parameters on land surface hydrological simulations. The results showed that meteorological forcing had the most significant influence on the output. Additionally, soil texture information greatly affected soil moisture simulations, while snow parameterization schemes in the land surface model had a significant impact on snow depth simulations. The study revealed that using a refined land surface model driven by observation-based regional meteorological forcing and land surface parameters can improve the modeling of regional land surface hydrological processes.

Summary: Arctic Amplification (AA), characterized by greater warming in the Arctic compared to the global mean, exhibits a seasonal dependence. Models predict that the annual maximum AA will shift from autumn to winter over the 21st century, but there is considerable uncertainty in the exact timing and magnitude of this shift. Model differences dominate the total uncertainty, while emission scenarios have a negligible impact on AA projections.

Summary: The importance of ecosystem services in water resources management has led to a focus on environmental-flows requirements for moving waters. However, current management practices often overlook the contribution of groundwater and fail to consider its importance in environmental flows. This study presents two methods for estimating groundwater environmental flow contributions, one based on groundwater and the other on surface water. The methods were tested in British Columbia, Canada and showed comparable results, suggesting their potential applicability in data-scarce, hydrologically complex landscapes globally.

Summary: This study focused on the spatiotemporal variability of diverse parameterization schemes in the soil hydrothermal simulations using the Noah-MP land surface model. Results revealed the different spatial and temporal effects of parameterization schemes, with energy-related schemes being sensitive to ground and soil temperature, and vegetation-related schemes playing a role after the growing season begins. Soil water content showed strong sensitivity to schemes related to both water and energy transport, while the sensitivity of energy-related schemes weakened when simulating total soil moisture, indicating their impact on soil freeze-thaw processes.

Summary: Deforestation affects the exchange of heat, moisture, and momentum between the Earth's surface and the atmosphere, leading to significant impacts on surface energy balance and water budget. However, simulations from different models show diverse changes in surface heat fluxes due to deforestation. This study investigates the factors causing these variations and uses the NCAR Community Land Model to explore the impacts of tropical deforestation on surface heat fluxes. Results demonstrate that changes in surface heat fluxes are related to the initial conditions of flux partitioning over deforested areas. Deforestation tends to reduce surface heat fluxes when evaporative fractions are smaller, and decrease latent heat fluxes while increasing sensible heat fluxes when evaporative fractions are larger. Similar findings in the Land Use Model Intercomparison Project suggest that varying simulated flux partitioning conditions contribute to the diversity in surface heat flux changes among models.

Summary: Environmental change, especially water crises, is a crucial driver of human migration, particularly in vulnerable regions and low- and middle-income countries. However, the interconnected patterns between water-related events and migration are not yet fully understood. This study combines quantitative text-mining with qualitative thematic analysis to explore these patterns and identifies four major patterns of water-driven migration: water quantity variability, damaging water hazards, physical disturbances to water systems, and water pollution. Understanding the dynamics of water-migration requires considering the interconnections between water changes and migration patterns, investigating the interactions between different water variables and socioeconomic factors, developing an integrated water-migration database for early-warning signals, and implementing targeted water policies to enhance resilience in climate-vulnerable regions and populations.

Summary: Groundwater, although being one of the largest reservoirs of water on Earth, has small fluxes compared to its volume. Deep groundwater (>500 m) is only weakly and sporadically connected to the rest of the terrestrial water cycle, contributing <0.1% to global streamflow. However, it plays a significant role in the global chloride cycle, providing around 7% of the flux of chloride to the ocean.

Summary: In this study, the impacts of the Pacific-Japan (PJ) pattern on the summer temperature and heatwave characteristics in Taiwan were investigated using long-term station-based temperature and rainfall dataset. The results showed that during the positive phase of the PJ pattern, there was an island-wide increase in temperature in Taiwan, accompanied by an increase in the effective area and frequency of heatwave extremes. The adiabatic warming due to subsidence anomaly associated with the anticyclone over Taiwan was identified as the primary contributor to the surface warming.

Summary: Managing groundwater is difficult due to its underground existence. The GRACE tool provides an opportunity for monitoring groundwater storage, but linking scientific research to policymaking and groundwater practices is limited. This paper aims to improve the use of GRACE data for sustainable groundwater management through a Delphi survey collecting opinions from academic and non-academic communities. The survey reveals the potential and willingness of both communities to collaborate and suggests recommendations for better application of GRACE data.

Summary: 'Urban Dry (Wet) Islands' (UDI/UWI) phenomenon has an impact on ecosystems and human well-being, but the causes are not fully understood. This study quantifies UDI and UWI using global observations and finds close linkages with local evapotranspiration, global warming, and 'Urban Heat Islands'. UDI is most pronounced in humid vegetated regions, while UWI is found in arid regions or climates with dry summers. The study suggests that evapotranspiration can be used as a single variable to explain emerging urban environmental changes and advocates for restoring nature's evapotranspiration power as effective solutions to mitigate the negative environmental effects of urbanization.
