Abstract Determining changes in water consumption behavior due to recurring external stressors (e.g. droughts and socio-economic fluctuations) previously unseen shocks like the COVID-19 pandemic can support future demand-side management (DSM) programs identifying vulnerable social groups. Yet, most studies analyzing drivers of change are noncomparative as they examine only one stressor at time, mainly droughts. Here we develop a multi-dimensional retrospective analysis (MDRA) quantify residential Southern California over last two decades under compound hydroclimatic, economic, stressors. We then uncover what groups relate predominant behavioral each stressor. observe long-lasting decreasing trend for more than 76% analyzed households. Socio-economically households were likely reduce during economic Differently, affluent neighborhoods tended increase or after pandemic. Our MDRA supports utilities policy makers discern impacts different on demand helps identify sensitivities across service area adaptive DSMs assistance programs.

With the pressing challenges of water scarcity and pollution, achieving sustainable management is imperative for promoting long-term development. Therefore, this paper aims to examine socio-economic cultural factors that shape sustainability strategies in Brazil Portugal. This study highlights various influence management, including robust legal frameworks, disparities, practices, agricultural usage, knowledge sharing, public participation, climate change resilience, risks, industrial consumption, urbanization. By conducting a SWOT analysis strategies, research synthesizes information through an extensive literature review, encompassing policies, implemented both countries. Additionally, it investigates comparative studies among Brazil, Portugal, other European nations facilitate exchange experiences practices. The findings offer valuable insights into strengths, weaknesses, opportunities, threats associated with thereby guiding development tailored policies foster resource management. role digital transformation optimizing integrating socio-economic, cultural, factors, contributes effective ensuring responsible utilization preservation resources.

Groundwater, a crucial freshwater source faces increasing pollution from microplastics (MPs). This study aims to comprehensively review the aquifers, sampling and analysis methods, levels, polymer types, sizes of MPs in groundwater worldwide between 2017 2023. Very few reports exist on abundance, type, size, other characteristics field. The tools, sample collection quantities used for field varied considerably among studies. However, efforts enhance our understanding MP results through level measurements, on-site water quality parameters, ion analysis, blanks have been limited. mostly indicated higher concentrations urban industrial areas landfill sites, whereas lower were observed with minimal human influence. are predominantly polypropylene polyethylene.

Abstract Context Supply of freshwater to the world’s cities is increasingly affected by human pressures and climate change. Understanding effects change on global urban water scarcity quality risks in an integrated way important. Objectives The objective this study assess security for 304 large (population > 1 million) across world 2015 2050. Methods We assessed according demand availability, evaluated supply terms population density, cropland fertilization, landscape patterns source watersheds. In addition, impacts were quantified using contribution analysis. Results found that about 90% these faced 2015. number facing risk was three times risk, nearly a quarter dual risks. From 2050, 88.8–99.7% projected face rising with one-third Increase main cause risk; growth crop fertilization watersheds reasons risk. Conclusions There urgent need promote conservation areas, implement sustainable planning governance, improve infrastructure, refine ecological compensation regimes achieve security.

Climate change, population growth, and economic development exacerbate water scarcity. This study investigates the impact of drought on availability in Belt Road region using high-resolution remote sensing data from 2001 to 2020. The results revealed an average (precipitation minus evapotranspiration) 249 mm/year a declining trend region. Approximately 13% faces deficits (evapotranspiration exceeds precipitation), primarily arid semi-arid regions with high frequency. area deficit is expanding, intensity increasing. annual strongly related frequency droughts, i.e. decreases increased Drought exacerbates seasonal stress approximately one-third region, mainly Europe northern Asia, where frequently occurs during seasons low availability. more severe drought, larger negative anomaly critical role evapotranspiration variability also highlighted. research underscores importance understanding drought-induced changes availability, which crucial for sustainable resource management.
