Interactions between groundwater and surface water sustain groundwater-dependent ecosystems, provide baseflow to rivers, and regulate river temperature and biogeochemical cycles, amongst many other processes. These interactions occur in freshwater environments including rivers, springs, lakes, and wetlands, and in coastal environments via tidal pumping, submarine groundwater discharge, and seawater intrusion. Here, we use a data-driven approach to explore groundwater-surface water interactions research using 20,275 journal papers published between 1970 and 2023. Analyses show that research into groundwater-surface water interactions is highly multi-disciplinary, with growing contributions from the social and biological sciences. As in the case with many research areas, the number of groundwater-surface water interactions papers is rapidly increasing with over 1200 papers published per year since 2020. Drawing on our data-driven approach and expert knowledge, we synthesise current research trends and identify critical future research directions. Despite the thousands of papers on groundwater-surface water interactions, there are still important processes that are difficult to quantify or predict at meaningful spatial scales to inform management. We see benefits in future groundwater-surface water interactions research focusing on: (1) embracing new technologies including the use of internet-of-things-based sensors and further use of uncrewed vehicles in data capture and remote sensing approaches to inform groundwater-surface water interactions at large scales, (2) capitalising on the increased computational power, availability of physically based models, and machine learning to inform hydrological and biogeochemical processes, and (3) continuing the movement towards multi-disciplinary investigations to better inform the quantification of groundwater-surface water interactions that will enable better management outcomes. © 2024, The Authors.

An edible film is a type of bioplastic packaging that can be used to package strawberries. Therefore, this study aimed to determine the packaging effect using nanobiocomposite edible film based on gelatin/nanocrystalline cellulose with the addition of antioxidants nanopropolis and storage temperature on the quality and shelf life of strawberries. The strawberries fruit were packed with edible film nanobiocomposite and stored at 5°C, 10°C, and 30°C. The parameters analyzed were water content, Vitamin C, hardness, total dissolved solids, pH, and shelf life. The results showed that the water content ranged from 23.95 to 65.89%w/b at the end of the storage period and was stable at 5°C and 10°C. Furthermore, hardness at the end of storage ranged from 0.265 to 0.431 kg/cm2 and all treatments experienced a decrease in Vitamin C content during storage. The total dissolved solids content at the end of storage was 5.92-12%Brix, with a shelf life ranging from 3-21 days of storage, as determined by all treatment parameters. These results showed that bionanocomposite edible film packaging can increase the shelf life of strawberries. © 2023, The Authors. All rights reserved.

Heavy metal contamination poses a significant threat to soil quality, plant growth, and food safety, and directly affects multiple UN SDGs. Addressing this issue and offering a remediation solution are vital for human health. One effective approach for immobilizing heavy metals involves impregnating cypress chips with calcium hydroxide (Ca(OH)2) to enhance the chemical adsorption capacity of the resulting woody charcoal. In the present study, un-treated cypress biochar (UCBC) and calcium-treated cypress biochar (TCBC), were introduced into pristine and contaminated soil, at rates of 3, 6, and 9% (w/w). Both BCs were alkaline (UCBC pH: 8.9, TCBC pH: 9.7) with high specific surface area, which improved the soil properties (pH, EC, and OM). Radish (Raphanus sativus) cultivated in pots revealed that both UCBC and TCBC demonstrated significant improvements in growth attributes and heavy metal immobilization compared to the control, with TCBC exhibiting superior effects. The TCBC surface showed highly active nanosized precipitated calcium carbonate particles that were active in immobilizing heavy metals. The application of TCBC at a rate of 9% resulted in a substantial reduction in Zn and Cu uptake by radish roots and shoots. In contaminated soil, Zn uptake by radish roots decreased by 55% (68.3–31.0 mg kg−1), and shoots by 37% (49.3–31.0 mg kg−1);Cu uptake decreased by 40% (38.6–23.2 mg kg−1) in roots and 39% (58.2–35.2 mg kg−1) in shoots. Uptake of Pb was undetectable after TCBC application. Principal component analysis (PCA) highlighted the potential of TCBC over UCBC in reducing heavy metal concentrations and promoting radish growth. Future research should consider the long-term effects and microbial interactions of TCBC application. © 2024 The Authors

The utilization of water treatment sludge (i.e., ferric sludge) was explored as the oxygen carrier (OC) for chemical looping combustion (CLC) of municipal solid waste (MSW) syngas. The performance of ferric sludge (FS) in CLC and simultaneous HCl removal was evaluated in a bench-scale fluidized bed, and was compared with iron ore (IO) as a benchmarked OC. The results show that FS (92%) performed better than IO (82%) in terms of syngas combustion efficiency and FS was able to remove HCl (77% removal efficiency) while IO was unable to remove any HCl. Comparison of reaction temperature reveals that FS performed better at lower CLC temperature between 800 °C and 850 °C. Agglomeration was observed when FS was used in extended CLC cycles. Thus, investigation of using inert a-Al2O3 support together with FS for extended CLC cycles was investigated. Agglomeration and sintering were drastically reduced and good combustion efficiency of 88% for H2 and 74% for CO was attained. Carbon footprint assessment illustrated that FS was superior as a greener material based on global warming potential of 20 and 100 years. Conversion of FS as an OC were characterized with 104.23 and 108.0 kgCO2/t lower than IO for GWP-20 and GWP-100, exhibiting the competitiveness in the usage of waste-derived material in CLC. Hence, FS can be considered as a novel, cost-effective, and greener OC for CLC. The co-utilization of waste-derived material and waste-derived syngas through CLC would be an integrated solution for improved circularity and sustainability. © 2023, The Authors.

In this study, integrated geostatistical techniques were applied to appraise the groundwater quality for various purposes in the Lower Anayari Catchment (LAC), Ghana. Physico-chemical and trace metals were analysed for 41 groundwater samples. Groundwater in LAC was generally found to be moderately hard to fresh and the information entropy-based groundwater quality index (IEGQI) ranked approximately 80.49% of the groundwater as excellent. Partial Least square regression analysis suggests that PO₄³⁻, As, Cd and Fe are important parameters for the prediction of IEGQI values. The irrigation water quality index (IWQI) suggest that 2.44% of groundwater in LAC is suitable for moderate permeability soils, 65.85% for moderate to high permeability soils and 31.71% for moderate to high salt tolerance plants. The LSI and RSI indices rate groundwater in LAC to be aggressive water with a high probability of being corrosive to metals, depending on the levels of dissolved oxygen present. © 2022 The Authors

Landfills are unique terrestrial ecosystems with some specific traits, such as extremely high heterogeneity, drastic exhaustion and accumulative stress from various toxic contaminants along with depth/age. However, the microbial community structure of this unique ecosystem is poorly understood. Here, we examined the microbial communities along with landfill depth and age (LDA) in a sanitary landfill in Beijing, China using 16s rRNA Illumina sequencing and GeoChip 4.6. Surprisingly, in contrast with the decreased microbial diversity along with depth in soil, we found that both phylogenetic and functional diversities were higher in deeper and older refuse in the landfill. Phylogenetic compositions were obviously different in the refuse with the same LDA and such difference is mainly attributed to the heterogeneity of refuse instead of random process. Nevertheless, functional structures were similar within the same LDA, indicating that microbial community assembly in the landfill may be better reflected by functional genes rather than phylogenetic identity. Dissimilarity test showed significantly different functional structures along with LDA. Higher abundance of stress response genes, organic remediation genes, and metal resistance genes in deeper and older refuse indicated that they may be required by microorganisms in response to the more stressful environments;and their significantly positive correlations with functional diversity implied that stress was an important factor influencing functional diversity. This study not only provides guidance for acceleration of landfill stabilization and in situ remediation, but also suggests a potential of landfill as the model ecosystem to investigate the response of microbial community to tolerable stress. © 2025, The Authors.

Indonesia currently is facing an energy crisis due to depletion of oil reserves and rapid growth in conventional energy consumption. The declining fossil energy potential especially oil and gas has encouraged the government to put new renewable energy(NRE) as the main priority to maintain energy security for national supply in the future. NRE in Indonesia is generated from bioenergy power, hydro power, solar power, tidal power, wind power, and potential. However, NRE utilization in Indonesia is only about 11% from the total potential. This study assesses the hydropower production capacity of Ayung River Basin, the biggest Basin in Province of Bali. The assessment is carried out by utilizing global data that can be easily accessed. It was found that there are several potential mini-hydropower locations around the Ayung River Basin, with the biggest potential is around 2 MW.

The aim of the current study was to provide a review of recent developments in solar desalination from the viewpoint of environmental, regulatory, and economic aspects. The analysis attempted to give better insight into the larger question of why more solar desalination plants are not being established by reviewing different technologies, drivers, barriers, and markets. Critical barriers which were dependent on the level of regional development were found to be uncertainty of government subsidies and a lack of regulatory policies. A new tool called a Pareto frontier may be utilized to generate optimal points in complex scenarios with a high number of variables. This all-inclusive method should be employed in any major decision-making process. Furthermore, in exciting innovative research studies, a sustainable Janus wood evaporator was developed that overcame many of the current solar desalination problems. While subsidies were crucial in the growth of renewable energy programs, barriers in deployment of solar desalination systems still exist such as low electricity tariff structures and fragmented energy policies. The overall trend was towards integration of renewable energy with conventional sources and energy storage systems. © 2023 The Author(s)
