Reducing food waste is an important initiative to ensure food security and mitigate climate change. Previous studies have largely ignored the influence of reference points on food waste behavior and the role of human-to-human relational interactions, failing to capture their role in guiding residents’ food waste behavior (RFWBs). To address this gap, this study proposes a model that examines the role of reference dependence, normative internalization, and symbolic expectations in RFWBs, while introducing network embeddedness as a moderating variable. Using data collected from 981 respondents online, ordinary least squares were used to test the hypotheses. The results showed that reference dependence and normative internalization had a positive effect on reducing RFWBs with regression coefficients of 0.178 and 0.293 respectively, while symbolic expectations also had a positive effect on RFWBs with a regression coefficient of 0.227. Additionally, Network embeddedness played a significant moderating role in reference dependence, normative internalization, and symbolic expectations with RFWBs. This paper is theoretically innovative and the relevant findings fill the current research gap in the field of food waste, providing guidance and reference for government departments to formulate policies and promote residents to implement food waste reduction behaviors.

Biochar is a promising material to improve soil quality. Effects of coconut shell biochar on tropical soil nitrogen mineralization and microbial community were less reported. The incubation experiment was conducted to observe the required effects. Biochar rates in latosol were 0%, 1%, 2% and 5% (w/w), respectively. Results showed: (1) soil pH and CEC improved with biochar rate; (2) urease activity was increased at the lower biochar rate (<2%) but reduced at the 5% rate, while acid phosphatase activity was not changed by biochar; (3) biochar addition reduced soil microbial diversity. The bacterial population like Proteobacteria, Gemmatimonadetes, Planctomycetes, Verrucomicrobia and Bacteroidetes enhanced by more biochar addition, while Actinobacteria and Chloroflexi were found less at the high biochar rate. Fungal strains like Ascomycota decreased by biochar addition, but Basidiomycota and Chytridiomycota increased at high biochar rates. Genus of Haematonectria, Chaetomium, Gibberella, Aspergillus, Fusarium and Eupenicillium decreased effectively under biochar addition; (4) soil nitrogen mineralization with biochar amendment was described well by the exponential model ( R 2 >0.95, P <0.01), but soil nitrogen mineralization potential was found to be less due to biochar application. Thus, the addition of biochar derived from coconut shells had positive effects on soil characteristics, microorganisms, and nitrogen mineralization.

Chemical fertilizer use efficiencies should be increased to reduce fertilizer quantities and potential negative impacts of excessive uses on soil and environmental health. Therefore, alternative soil nutrient sources are searched for and biological alternatives offer promising outcomes in this sense. In this study, effects of single, dual and triple combinations of phosphorous-solubilizing ( Bacillus megatherium var. phosphaticum [M-13]) and N-fixing bacteria ( Stenotrophomonas maltophilia [82] and Ralstonia pickettii [73]) treatments on plant growth, yield and yield component of barley were investigated and potential effects were compared with chemical fertilizers (N (80 kg ha -1 N), P (50 kg ha -1 P 2 0 5 ) and N+P (80 kg ha -1 + 50 kg ha -1 P 2 0 5 ) and Control treatments. The longest grain filling period was obtained from Ralstonia pickettii, Stenotrophomonas maltophilia and Bacillus megatherium var. phosphaticum + Stenotrophomonas maltophilia bacteria treatments. The highest number of spikes per m 2 , 1000-kernel weight, and test weight values were obtained from sole N treatments, the highest number of kernels per spike, protein content, grain yield, and biological yield from N+P treatments and the highest harvest index values from Ralstonia pickettii + Stenotrophomonas maltophilia treatments. In general, bacterial treatments resulted in significant changes in yield and yield parameters of barley and significant increases were achieved as compared to the Control.

Side weir is an effective control in streams. To study geometrical dimensions effect of the weir on the generated flow structure, here, experimental and numerical simulation analysis of the previous and present experimental studies was done on the flow around different geometric types of side weir. A triangular labyrinth side weir with three distinct included angles ( θ = 30 o , 45 o , and 60°) and three weir heights (P = 10, 15 and 20 cm) has been tested, in addition normal rectangular side weir for comparison. The volume of fluid (VOF) approach was used for tracking free-surface subcritical flow conditions at the centerline of the main channel and near side weir banks. Accurate results were discovered by employing the Renormalization Group (RNG k-∈ ) turbulence model with the experimental outcomes. The smallest inclusion angle of side weir, generates smaller width of vortices zone near the upstream side weir wall which obstacles only a smaller length of crest as compared to the larger inclusion angle that hindrances larger length of this side for flowing water. In addition the contribution portion of the surface flow for the smallest inclusion angle which is indicated by streamlines is about 0.66 times the main channel width. Moreover, the maximum width of separation zone at the downstream of the main channel reached to 0.8 times the width of the main channel for the triangular labyrinth side weir. The stagnation point exists at the downstream end of side weir results the increase of surface elevation to reach maximum level. The coefficient of discharge of such weirs were 3.8, 2.7 and 2.12 times the coefficient of the normal rectangular side weir for θ = 30 o , 45 o and 60°, respectively.

The second wave of industrialization at the end of the last century brought the attention of researchers to the effect of more energy usage and its effects on environmental degradation. It was also highlighted in the 2030 agenda for sustainable development goals (2015) that environmental degradation threatens humans’ well-being unless countries use environment-friendly production processes. The present study has used the Malmquist-Luenberger Index (MLI) to estimate the environmental efficiency of the Asia-Pacific (APAC) region for the period 1990 to 2019. The estimated results showed that the environmental efficiency of APAC countries declined by 0.36%, on average, in the studied period. The results also highlighted that the Republic of Korea has the highest total factor productivity (TFP) output growth rate in the APAC region. In contrast, Lao People’s DR and the Maldives have the lowest TFP. Conditional, unconditional, and Club convergence tests are also tested for the APAC region. The results also suggested that convergence in environmental efficiency is conditional on trade openness, industrial growth, and energy prices. Some policies are also suggested for the APAC region at the end of the study.

Low-carbon production has great potential to limit greenhouse gas emissions and protect the living environment. This research innovatively introduces green cognition into the theory of planned behavior (TPB) to validate the effect of green cognition on farmers’ low-carbon production behavior. In this research, we use structural equation model (SEM) to research the low-carbon production behavior of 265 farmers in Yilan County, Harbin City, China. Our results indicate that farmers’ perceived behavioral control (PBC) has a remarkable impact in generating their low-carbon production intention, while attitude (ATT) and subjective norms (SN) have no significant positive impact. Meanwhile, it is verified that the perceived behavioral control and behavioral intention (INT) of farmers have a significant positive impact on their low-carbon production behavior. In addition, the research also verifies that green cognition (GC) has a significant positive impact on farmers’ attitudes and subjective norms of low-carbon production behavior, and green cognition may indirectly affect low-carbon production behavior through farmers’ subjective norms and intention pathways, reflecting that the extended theoretical framework of planned behavior is applicable to the research of farmers’ low-carbon production behavior.

Species distribution models are the most useful tools that reveal the relationships of target species with environmental variables. The most frequently preferred environmental variables are bioclimatic parameters due to their ability to be interpolated into the future. Bioclimatic variables can be downloaded from various databases at different resolutions. The aim of the present study is to reveal the effect of resolution preference on species distribution models. Ambrosia artemisiifolia and Ailanthus altissima , two invasive species, were selected as target species. These species have large potential distributions. In addition, studies indicate that their distribution is increasing rapidly. Therefore, it poses a threat to both human health and biodiversity. In the present study, a significant difference was found between the predictive values obtained with different resolutions for both species. It was also observed that the model with the highest AUC values was obtained with bioclimatic variables that have 10 arc minutes resolution for both species. The AUC values showed that the models had excellent explanatory power. Finally, potential suitable areas covering almost all of Europe were identified for the two invasive species. It is thought that these species may pose a serious threat in terms of both biodiversity and human health if careful attention is not exercised in the planning.

An objective and complete assessment of the carbon footprint of rice-fishery co-cropping model is critical for the rice-farming industry’s low-carbon and green growth. Based on field experiments and the life cycle assessment (LCA) methodology, a comprehensive carbon footprint assessment of rice monoculture, rice-shrimp co-cropping, and rice-crab co-cropping models was conducted in this study, and the NEEB of different rice farming models was calculated based on the economic benefits. The carbon footprints per unit area of rice monoculture, rice-shrimp co-cropping, and rice-crab co-cropping models were 14122.65 kg (CO 2 -eq)·hm -2 , 13791.78 kg (CO 2 -eq)·hm -2 , and 15617.13 kg (CO 2 -eq)·hm -2 , respectively, according to the data. Hotspot analysis revealed that the carbon footprint composition of the rice-shrimp and rice-crab co-cropping models was influenced more by CH 4 emissions, energy use, and feed inputs. Due to the greater economic production values of rice-shrimp and rice-crab co-cropping modes, the NEEB of these two modes increased by 81.45% and 69.52%, respectively, as compared to rice monoculture. Overall, rice-shrimp and rice-crab co-cropping models can reduce emissions and improve paddy field efficiency to some extent when compared to rice monoculture and rice-crab co-cropping models, but attention should be paid to the point of trade-off between carbon footprints and economic benefits in order to promote the green and efficient development of the rice-fishery co-cropping model. The technique utilized in this work can give technical assistance for a more thorough carbon footprint assessment of multifunctional agricultural production systems.
客观、全面地评估稻渔共作模式的碳足迹对稻米种植业的低碳和绿色发展至关重要。本研究基于田间试验和生命周期评估（LCA）方法，对水稻单作、稻虾共作和稻蟹共作模式进行了全面的碳足迹评估，并根据经济效益计算了不同稻作模式的NEEB。数据显示，水稻单作、稻虾共作和稻蟹共作模式的单位面积碳足迹分别为 14122.65 kg (CO 2 -eq)-hm -2、13791.78 kg (CO 2 -eq)-hm -2和 15617.13 kg (CO 2 -eq)-hm -2。热点分析表明，稻虾共作和稻蟹共作模式的碳足迹构成受 CH 4 排放、能源使用和饲料投入的影响较大。由于稻虾共作和稻蟹共作模式的经济生产价值更高，与水稻单作相比，这两种模式的净减排量分别增加了 81.45% 和 69.52%。总体而言，稻虾共作模式和稻田共作模式与水稻单作模式和稻田共作模式相比，能在一定程度上减少排放，提高稻田效益，但应注意碳足迹与经济效益之间的权衡点，以促进稻渔共作模式的绿色高效发展。本研究采用的技术可为更全面地评估多功能农业生产系统的碳足迹提供技术帮助。

Hotspot analysis revealed that the carbon footprint composition of the rice-shrimp and rice-crab co-cropping models was influenced more by CH 4 emissions, energy use, and feed inputs. Due to the greater economic production values of rice-shrimp and rice-crab co-cropping modes, the NEEB of these two modes increased by 81.45% and 69.52%, respectively, as compared to rice monoculture. Overall, rice-shrimp and rice-crab co-cropping models can reduce emissions and improve paddy field efficiency to some extent when compared to rice monoculture and rice-crab co-cropping models, but attention should be paid to the point of trade-off between carbon footprints and economic benefits in order to promote the green and efficient development of the rice-fishery co-cropping model. The technique utilized in this work can give technical assistance for a more thorough carbon footprint assessment of multifunctional agricultural production systems.","PeriodicalId":20363,"journal":{"name":"Polish Journal of Environmental Studies","volume":"31 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139228687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
