Promoting household adoption of water conservation behaviors (WCBs) has emerged as a vital strategic response to address water scarcity. Nevertheless, it is imperative to recognize that acceptance of residential WCBs relies on households' voluntary engagement, as are interventions designed to encourage households to become involved in such actions. Meanwhile, environmental psychology plays a key role in understanding individuals' WCBs and exploring the psychosocial determinants underlying these behaviors. Furthermore, the spread of technology and behavior among a population are known as a complex adaptive system (CAS), and agent-based modeling (ABM) offers a comprehensive and practical approach to studying CASs. Hence, the main aim of the present research is to introduce a novel, hybrid agent-based framework for simulating the adoption of residential WCBs, in which an extended model of the theory of planned behavior acts as household agents' behavioral rule for adopting water-efficiency behaviors (WEBs). The framework is also grounded in various theories rooted in psychological and social sciences. Moreover, the presented framework integrates ABM and structural equation modeling approaches. Although this study mainly focuses on WEBs, the framework includes a mechanism to update agents' water use based on their adoption level of water curtailment behaviors. Thus, the presented framework allows for simultaneously but separately exploring the preferred level of both types of WCBs among household agents. Finally, total water consumption is systematically calculated based on agents' aggregated behavior. © World environmental and water resources Congress *** rights reserved

Irrigation networks play a crucial role in water distribution and food production in agricultural systems and contribute to the overall economy. While studies have examined the effects of organic chemical pollutants, including pesticides, on crop and soil health, there is a lack of research on the overall composition and occurrence of organic chemical contaminants in irrigation water. To this point, there are currently no standardized methods for monitoring contaminants and assessing the transformation and potential toxicity of these compounds in irrigation water distribution systems. In this study, we used liquid chromatography high-resolution mass spectrometry to analyze the organic chemical composition of water samples from an irrigation canal and a river that serves as the source of water for the canal. We estimated the relative evaporation rate in the canal as a proxy for residence time by measuring the isotopic ratio of hydrogen and oxygen in the canal water with cavity ring-down spectroscopy. We assessed adverse effects of chemical contaminants in our samples by evaluating the collected water with a high-throughput zebrafish embryonic platform. We evaluated the hazard of annotated chemicals with an assessment tool developed by the US EPA. The canal showed a greater decrease in the abundance of organic contaminants relative to the river as we moved further from the source. Evaporation, a proxy for residence time, was evaluated in the canal and increased after a holding reservoir due to its higher surface area relative to the rest of the canal. This study improves our understanding of the occurrence and degradation of organic chemicals in irrigation networks compared with rivers, and how they may correlate with evaporation and distance. The approach implemented in this study can help build a standardized methodology for monitoring water quality and assessing the potential toxicity of organic contaminants in agricultural irrigation systems. © 2024, The Authors.

As populations and affluence grows, increased demand for food drives a concomitant increase in associated water scarcity. A relative and absolute increase in crop-embodied virtual water traded between countries is a geopolitically important component of this scarcity. In addition to biophysical dimensions, blue water consumption can have varying impacts on humans and biodiversity. This study focuses on virtual water trade relating to consumption of crops and crop products, and its related socio-ecological impacts, in a water scarce country with high reliance on virtual water, Israel. The results of two established methodologies are assessed, in calculating consumption associated with the virtual water trade of up to 100 crops. Using virtual water quantifications from the methodology with higher spatial resolution, together with two complementary sets of characterisation factors from life cycle impact assessment methodologies (water scarcity indices and potential disappeared fractions) a novel comparison of impacts on ecosystems relating to loss of species and water denial is facilitated. As an additional impact indicator, groundwater depletion is calculated for the virtual water trade of a narrower set of crops. Israel's crop production was found to be associated with outsized cumulative blue water consumption volumes, relative to imports. In addition, regional and country hotspots of blue water consumption, groundwater depletion, downstream user impact and biodiversity loss were identified, including in India, The United States, and the Mediterranean region. Several limitations and suggestions for future application are discussed. © 2024 The Authors

Manggarai Gate is one of the most important flood control structures of the Jakarta Flood Control System. Its performance capacity is a compulsory parameter for flood risk reduction of the Jakarta Flood Prone Area. This paper aims to evaluate the contribution of the capacity improvement of Manggarai Gate to reduce the flood hazard at Manggarai flood-prone areas located in the upper part of this gate. An additional gate section was conducted in 2015 as the structural flood hazard reduction effort to increase the capacity of this gate from 330 m3/s to 507 m3/s. Recorded floods characteristic event before and after this improvement was compared to determine the flood hazard changes during the flood observation period. Based on this determination results it is found that the contribution of the increment capacity of Manggarai gates in reducing the flood hazard depends on the sustainability of the river capacity, river water quality, and flood control operation. It could also be concluded the sustainability of the river capacity and river water quality is very sensitive to the social behavior of the community and the river stakeholder along the river catchment area in addressing the environmental condition of the river catchment area. © Published under licence by IOP Publishing Ltd.

Collaboration in the management of mangrove areas is a role for every social element in an area government, community, and private parties. Co-management is an alternative solution in the form of management that integrates the roles and interests of everyone in the mangrove rehabilitation program. This study aims to analyze the role and level of influence of the interests of each actor in mangrove rehabilitation activities in Langkat Regency. The research method uses descriptive-qualitative, data collected from the results of questionnaires, interviews;field observations are processed in the form described in the description on the tabulation. From the results of this study, the form of co-management in mangrove rehabilitation is at a consultative stage where the government begins to consider local views in the decision-making process, the level of participation of each stakeholder in the low category, so this study recommends that the form of participation of each stakeholder can be increased through the form of regulations together, a program of sustainability and systematic distribution of work that is socialized to every implementer of the mangrove rehabilitation program in Langkat District. © The Authors, published by EDP Sciences, 2020.

environmental impacts of small scale industries are still not well investigated, especially for estates where multiple small scale industries are clustered causing cumulative effects potentially impacting most vulnerable groups. This study aimed to investigate the concentrations of heavy metals (Mn, Fe, Ni, Cu, Pb, Al, Zn, and Cr) and the metalloid (As) in surface soils near the intensely active small-scale industrial area in Thailand, assess the contamination levels in the co-located child care center, and estimate potential human health risks from exposure to the heavy metals. Surface soil heavy metal(loid) elements were evaluated across a background area, area near main roads, a small-scale industrial area, and a child care centre. The concentrations of Al were found be the highest at all investigation sites, with the most elevated concentrations observed in the small-scale industrial area. The concentration of Pb in the industrial area reached 1176 mg/kg, exceeding the national standard and acceptable limit. Moreover, the contamination level for Cu, Pb, and Zn in the industrial area imply a considerable risk with enrichment factor EF > 40, and geo-accumulation index Igeo ≥5. Heavy metal levels (Ni, Cu, Pb) in the soil near the road and the child care center were similar, suggesting shared contamination sources. Conversely, Al, Zn, As, and Cr in the child care center had slightly higher concentrations than near the road but lower than the small-scale industrial area, indicating potential industrial influence on metal levels within the child care center. The principal component analysis showed Mn and Fe distributed in the background, while As, Pb, Ni, Cu, Al, Zn, and Cr accumulated in the small-scale industrial area. The findings indicate that small-scale industrial activities contribute to elevated levels of heavy metals in the soil, particularly within the child care center, posing significant ingestion risks, especially for children (HI > 1).

Adsorption of organic and inorganic pollutants onto biochars: Challenges, operating conditions, and mechanisms

引用

Bioresource Technology Reports 2021年 15卷

作者： Barquilha, Carlos E.R. Braga, Maria C.B. Postgraduate Program in Water Resources and Environmental Engineering Parana Federal University Av. Cel. Francisco H. dos Santos 100 CuritibaPR CEP81530-000 Brazil

The presence of toxic substances in the environment has increased due to population growth, urbanization, industrialization, as well as changes in people's lifestyles. Among many technologies, adsorption has proven to be an effective and inexpensive technique for water and wastewater treatment. Biochar has been identified as a promising and low-cost material, which can be produced from various carbonaceous materials with different origins, compositions, and processing methods. Consequently, the interaction between biochars and adsorbate species is not simple and may involve different adsorption mechanisms, such as van der Waals forces, electrostatic interactions, surface complexation, ion-exchange, hydrophobic interactions, π-interactions, co-precipitation, partition, and pore-filling. In addition, many operating conditions can affect the performance of adsorption processes. However, the development of biochars as competitive adsorbent materials depends on standardization, continuous-supply, application, and regulation. Thus, this paper discusses the challenges, the operating conditions, and the adsorption mechanisms to remove organic and inorganic micropollutants using biochar. © 2021 Elsevier Ltd
