Summary: This study developed a novel strategy for achieving partial nitrification-anammox (PNA) in an integrated vertical subsurface flow constructed wetland (VSFCW) to improve the removal of nitrogen in rural domestic sewage. The strategy involved oxidizing ammonia to nitrite in the partial nitrification VSFCW and then removing ammonia and nitrite through the autotrophic anammox process in the following chamber. The results showed high removal efficiencies for chemical oxygen demand, total nitrogen, and PO43--P, confirming the feasibility of the proposed strategy.

Summary: This study investigates the potential of 14 tropical wetland plant species for removing heavy metals from domestic sewage. The results indicate that most plants can act as magnesium phytostabilisers and calcium phytoextractors, but no plant species demonstrated ferrum phytoextraction properties. Only three species depicted phytoextraction and phytostabilisation properties for manganese phytoremediation. The enrichment factor (EF) for all studied metals decreased after the phytoremediation experiments, indicating depletion to mineral enrichment (EF < 2).

Summary: The study found that using ceramsite and soil as media in VFCWs can effectively remove fluoroquinolones and conventional pollutants in rural domestic wastewater. Under low hydraulic load, VFCW-D filled with 45 cm soil layer and 15 cm ceramsite layer had the highest removal efficiency. However, under high hydraulic load, the removal efficiency of conventional pollutants significantly declined due to the clogging of soil pores by organic matter accumulation. Nevertheless, VFCW-A filled with 60 cm ceramsite layer showed good ability to remove both conventional pollutants and fluoroquinolones under high hydraulic load.

Summary: The biggest problem in treating rural domestic sewage is the high investment and operating costs of existing treatment projects. To address this issue, cost-effective, low-consuming, resource-recovering, and easy-maintenance technologies are urgently needed. In this study, a novel anoxic-aerobic system combined with integrated vertical-flow constructed wetland (IVFCW) with source separation was proposed. The system achieved high removal rates of COD (91.58 +/- 1.86%), NH4+-N (96.17 +/- 0.92%), TN (82.71 +/- 3.92%), and TP (92.28 +/- 2.78%) under optimal operating parameters. Compared to other treatment technologies, this combined bio-ecological system showed higher simultaneous removal of organics and nutrients, making it a promising and competitive alternative for rural sewage treatment.

Summary: This study applies Elinor Ostrom's Institutional Analysis and Development (IAD) extension model to understand the factors influencing agricultural households' decision to work in rural tourism in China. The study identifies five key variables: land consolidation, market characteristics, institutional arrangements, farming household's understanding of tourism, and household information. Binary logistic regression analysis reveals that market characteristics and cognition have direct positive influences on farmers' willingness to provide tourism services, while the source of household income has a negative influence. The study also finds no difference in risk assessment between farmers who work in tourism and those who do not, but significant differences in other factors. Finally, implications are provided for optimizing rural tourism development.

Summary: This paper reveals the strategic coevolution mechanism of polycentric waste governance's main stakeholders at the community level through evolutionary game theory. The study shows that the recycler ultimately chooses active participation, while the community and householders are hesitant. Transmission effects exist in the interactions among the three agents. The modeling analysis echoes the tragedy of the commons and market failure in the theoretical landscape of polycentric waste governance. Countermeasures such as community engagement, public perception, and innovative government-market cooperation mode deserve attention. By uncovering the 'black box' of the polycentric waste governance model, a better understanding of the strategic evolution mechanism of governance actors for improving the theory is obtained. The research findings are expected to enlighten the practice of polycentric waste governance and mitigate the dilemma of waste siege.

Summary: The social contact rate plays a significant role in the transmission of COVID-19, where higher social contact leads to more contagion cases. This study examined 18 countries with the highest number of confirmed cases in the first 200 days after the Wuhan lockdown. A General Dynamic Model was developed to simulate the epidemic under various restriction policies for 500 days since the outbreak. The findings showed that the probability of contagion ranged from 12.52% to 39.39%, and the social contact rates varied significantly among countries, from 18.21% to 96.00%. Developed economies had 3.5 times more effective restriction policies compared to developing economies. The study compared the effectiveness of different policies for disease prevention and discussed the impact of policy adjustment frequency for each country. The recommendation was to maintain the strictest restrictions or adopt alternating tightening and loosening measures, resulting in an average reduction of maximum active cases by 72.45% and 79.78%, respectively.
