Microplastics have garnered much attention worldwide as a new emerging pollutant, especially because of their eco-toxicological effects in marine environments. As they are gradually detected in freshwaters, understanding how microplastics, with their small particle size and low density, will behave during current drinking water treatment processes is urgently needed. In this study, Al- and Fe-based salts were used in the presence of polyethylene (PE), which is suspended/floats easily in water and is the main constituent of microplastics. Results showed that Al-based salts performed better in PE removal efficiency than Fe-based salts. The smaller the PE particle size, the higher the removal efficiency. However, a low removal efficiency was observed, even with a high Al-based salt dosage of 15 mM (below 40%). Additionally, water conditions, such as ionic strength, turbidity level, barely influenced the removal efficiency. In comparison to pH, polyacrylamide (PAM) addition played an important role in removing PE; especially anionic PAM addition, because of the positively charged Al-based flocs it generates under neutral conditions. For ultrafiltration, although PE particles can be completely rejected, slight membrane fouling was induced after coagulation with conventional Al-based salts. With increasing dosage, membrane fouling was gradually aggravated owing to the thick cake layer formed. However, the larger the PE particles, the greater the roughness of the Al-based floc cake layer, leading to less severe membrane fouling. Based on this investigation, the microplastic removal behaviors exhibited during coagulation and ultrafiltration processes have potential application in drinking water treatment.

Climate change affects the livelihood of farmers in a variety of ways. Farmers’ indigenous knowledge influences their perception of climate-related issues. A perception-based, semi-structured questionnaire survey of 530 households was performed to gather information about the awareness of, indicators for, and determinants of climate change. The survey covered three ecological regions of Nepal. The statistical analysis was done with a chi-square ( 2) test and a binary logistic regression (BLR) model to screen farmers’ perception of climate change. This study shows that socio-economic and agricultural characteristics of the farmers directly influence their perception of climate change. Farmers have identified climate change indicators in various forms, e.g., an increase in temperature (99.2% of those surveyed), a decrease in precipitation (98.9%), and an increase in climate-induced diseases and pests (96.8%) for agricultural crops. Observed precipitation (- 16.093 mm/year; p = 0.055) and temperature (0.0539 °C/year; p = 0.007) between 2000 and 2015 are both consistent with farmers’ perception. The selected independent variables are significantly correlated with the dependent variables, as confirmed by the BLR model, where 2 = 83 with p = 0.002. The BLR shows there is a strong relationship between farmers’ perception of climate change and the group of descriptive variables, with a coefficient of determination of 85%. The biophysical characteristics and impact variables were the most important determinants. It is important that organizations and policymakers in Nepal develop adaptation strategies that improve the livelihoods of farmers. These strategies include introducing drought-tolerant crops, developing disease- and pest-tolerant seeds, constructing irrigation systems, and building hospitals.

Climate change will impact every aspect of biophysical systems and society. However, unlike other components of the climate system, the impact of climate change on the groundwater system has only recently received attention. This focus is due to the realization that groundwater is a vital freshwater resource crucial to global food and water security, and is essential in sustaining ecosystems and human adaptation to climate variability and change. This paper synthesizes findings on the direct and indirect impacts of climate change on the entire groundwater system and each component. Also, we appraise the use of coupled groundwater-climate and land surface models in groundwater hydrology as a means of improving existing knowledge of climate change-groundwater interaction, finding that most models anticipate decreases in groundwater recharge, storage and levels, particularly in the arid/semi-arid tropics. Reducing uncertainties in future climate projections and improving our understanding of the physical processes underlying models to improve their simulation of real-world conditions remain a priority for climate and Earth scientists. Despite the enormous progress made, there are still few and inadequate local and regional aquifer studies, especially in less developed regions. The paper proposes two key considerations. First, physical basis: the need for a deeper grasp of complex physical processes and feedback mechanism with the use of more sophisticated models. Second, the need to understand the socioeconomic dimensions of climate-groundwater interaction through multidisciplinary synergy, leading to the development of better groundwater-climate change adaptation strategies and modeling.

The Yellow River Basin (YRB) is facing a serious water shortage. How to effectively alleviate the water crisis and achieve sustainable development in the YRB has become a widespread concern. By using the interregional input–output tables of China in 2002, 2007, 2012 and 2017, we analysed the transfer of virtual water and value-added and the inequality embodied in trade between the YRB and other regions. Results demonstrated that: (1) for the YRB, the pressure on water resources was alleviated through the net inflow of virtual water after 2007. However, the economic situation deteriorated due to the net outflow of value-added in interregional trade after 2012. (2) There existed a serious inequality in virtual water consumption and economic benefits embodied in trade between the YRB and Beijing, Shanghai, etc., with regional inequality (RI) index exceeding 1. Meanwhile, agriculture faced the most serious inequality among all sectors in the YRB. Accordingly, the YRB should aim to optimise its industrial structure and improve water use efficiency to achieve a win-win situation for both economic development and net virtual water inflow. In addition, policymakers should take measures to flexibly adjust the trade scale between the YRB and other regions based on the RI index.

Agricultural sustainability is threatened by pressures from water scarcity, energy crises, escalating greenhouse gas (GHG) emissions, and diminishing farm profitability. Practices that diversify crop rotations, retain crop residues, and incorporate cover crops have been widely studied for their impacts on soil organic carbon and crop production. However, their associated usage of natural resources and economic returns have been overlooked. Here, we employed a food-energy-water-carbon (FEWC) nexus framework to assess the sustainability of crop rotations plus various management strategies across three sub-regions of New South Wales (NSW) in Australia. We found that compared with residue burning and fallowing, residue retention and cover cropping contributed to GHG abatement, but the latter consumed more energy and water per hectare. The composite sustainability scores, calculated with the FEWC framework, suggested that legume-inclusive rotations were generally more sustainable. Furthermore, in northern NSW (with existing sorghum/wheat/chickpea/wheat rotation), residue retention with cover cropping was most suitable combination, while the use of residue retention with fallow yielded greater benefits in southern NSW (with existing wheat/field pea/wheat/canola rotation). Regional disparities in climate, soil, cropping systems, and on-farm costs prompted region-specific strategies to address the unbalanced distribution among FEWC domains. Our study provides assessments for identifying feasible management practices to advance agricultural sustainability.
