Summary: This article summarizes the findings of studies on the relationship between farmers' behavioral intentions and water-conservation behavior using the theory of planned behavior. The results show that attitude, subjective norms, and perceived behavioral control are all associated with behavioral intentions, with attitude having the strongest correlation. Furthermore, behavioral intentions have a strong relationship with water-conservation behavior. These findings have important implications for policymakers in developing solutions and policies for water resource management.

Summary: Promoting residential water conservation is crucial in addressing water shortages caused by increasing water demand. A questionnaire survey of 514 Japanese adults was conducted to measure how various social, psychological, and behavioral variables influence individual water use and conservation behavior. The study found that families are more likely to adopt water conservation practices and use less water if they have positive attitude, greater awareness and responsibility about water issues, stronger emotions, habits and involvement in water-saving initiatives or campaigns. The suggested model explained 55% and 57% of the variation in water consumption and conservation behavior.

Summary: Occupant behavior has a significant impact on building energy consumption. This study aims to fill the research gaps related to firsthand data on occupant behavior and the consideration of socio-psychological factors in behavior mode classification. The research findings show that behavior patterns can vary even among users of the same type, with factors such as room orientation, floor, schedule, room temperature settings, and behavior modes of active, moderate, and cautious users explaining the majority of the difference in cooling energy consumption. Additionally, technical and socio-psychological barriers hinder energy savings for active and moderate users, highlighting the importance of selecting appropriate interventions for behavior changes to achieve energy conservation goals.

Summary: A multi-dimensional retrospective analysis (MDRA) method was developed to study residential water consumption changes in Southern California over the last two decades under compound hydroclimatic, economic, and pandemic stressors, and to identify socio-economic groups related to predominant behavioral changes under each stressor. The study found a long-lasting decreasing water consumption trend for more than 76% of the analyzed households. Socio-economically vulnerable households were more likely to reduce water consumption during the economic and pandemic stressors, while affluent neighborhoods tended to increase water consumption during or after droughts and the pandemic. The MDRA can help utilities and policy makers understand the impacts of different stressors on water demand and identify social and economic sensitivities to develop adaptive demand-side management and assistance programs.

Summary: Recycled cement is obtained by heat treating hydrated cementitious materials. It does not undergo decarbonation at 550 degrees C due to low CO2 emissions during production. Although a partial regain of the binder ability is observed during rehydration, recycled cement has limited strength due to its physicochemical characteristics, which require elevated water demand.

Summary: Freshwater microplastics are influenced by anthropogenic factors such as urbanization, population density, and wastewater treatment plant effluent, as well as physical watershed characteristics like slope and elevation. Precipitation and stormwater runoff have positive correlations with microplastic concentrations, while water flow/discharge has negative correlations. Variations in study results may be attributed to differing scales or contributing area delineations, indicating a need for more rigorous and standardized spatial analytical methods.

Summary: Wildfires have become more severe and frequent due to climate change and human activities, posing a threat to water-related ecosystem services. Previous research on post-fire hydrologic effects focused mostly on water quantity, with less attention given to stream temperature and turbidity. This study examined the drivers and processes of turbidity and stream temperature changes following wildfires through a geographic lens. The findings highlighted the influence of fire severity, forest diversity, and human activities on turbidity changes, as well as the site-specific nature of stream temperature increases. Variabilities in these changes were attributed to climate variability and disparities across spatial and temporal scales. The study recommends incorporating long-term monitoring efforts and spatiotemporally explicit models in future research to better understand the complex post-fire hydrologic system and its impact on water quality.

Summary: We developed a novel spatial stream network geographically weighted regression (SSN-GWR) model by incorporating stream-distance metrics into GWR. The model was tested for predicting seasonal total nitrogen (TN) and total suspended solids (TSS) concentrations in relation to watershed characteristics. Compared to the standard GWR model, the SSN-GWR model generally provided better model fit, reduced residual spatial autocorrelation, and lessened overall modeling errors. The results demonstrate the importance of integrating stream distance into GWR for improving model fit and understanding hydrological processes related to water quality in a complex river basin. The local variations in model fit derived from this work can be used to devise fine-scale interventions for water quality improvements.

Summary: Although wildfires in the western contiguous United States (WCONUS) have become more frequent and severe, the impact of these fires on streamflow trends is not well understood. This study used geographically weighted regression (GWR) and multi-scalar GWR to examine how spatially varying watershed characteristics, including burn severity patterns, could explain streamflow trends. The results showed that GWR models reduced spatial autocorrelation and provided insights into regional factors influencing streamflow. However, burn severity-based metrics were generally not significant in explaining streamflow trends, except for the model that incorporated the spatial arrangement of high severity patches. Positive and negative peak flow trends were associated with increasing landscape shape index (LSI) values in different regions of WCONUS. This research could inform post-fire response strategies and the development of new spatial metrics for post-fire hydrological processes.

Summary: Flooding occurrence in cities is affected by the characteristics of social, ecological, and technological systems at different scales. This study examines the relationship between flood exposure and SETS drivers of flood vulnerability, finding that flood exposure is correlated with SETS variables at the parcel scale and varies among cities. Marginalized populations are more exposed to future flooding at the CBG scale. Assessing exposure and vulnerability using high-resolution future flood risk estimates and SETS data can assist city managers in planning equitable interventions.

Summary: This study examines the impact of land cover, vegetation health, climatic forcings, elevation heat loads, and terrain characteristics on land surface temperature distribution over West Africa. The random forest model performs the best in downscaling predictands. The southern regions consistently exhibit healthy vegetation, while areas with unhealthy vegetation coincide with hot land surface temperature clusters. Positive Normalized Difference Vegetation Index trends in the Sahel highlight rainfall recovery and subsequent greening. Southwest winds cause the upwelling of cold waters, resulting in low land surface temperatures in southern West Africa. Considering LVCET factors is crucial for prioritizing greening initiatives and urban planning.
