“…Organic farming systems use biological and physical controls instead of synthetic fertilizer and prevent groundwater pollution, increase microbial biodiversity, and are less reliant on external inputs [56][57][58]. The main sources of N 2 O emissions to the atmosphere are nitrification proceeded by denitrification processes carried out by soil microorganisms, though these emissions can change based on agricultural waste management, soil tillage, nitrogen fertilizer used, and climate conditions [50].…”

“…The conventional farming strategy relies on a chemical technology in which an extra supplement is applied to improve productivity. Several studies have shown that these practices affect the ecosystem and also have impacts on human health [2,46,50,51]. Agrochemical contamination has a long-term impact on humans, food chains, and the environment.…”

“…In terms of nutritional levels and solubility, the impacts of organic replacements are obviously a major cause for worry for P loss through surface runoff [68]. According to reports, phosphorous is the most important element in eutrophication intensification among other inputs [37,[50][51][52][53][54][55][56]. In rice cultivation, one way for phosphorous to enter water sources is by leaching [69,70].…”

“…Except for the marine eutrophication potential (MEP), terrestrial acidification potential (TAP), and global warming potential (GWP), the highest emissions and negative environmental effects could be identified in the conventional system of farming in 11 impact categories. Several studies have already indicated that organic agriculture has a lower environmental impact than conventional agriculture, as avoiding chemical use in rice production has various environmental advantages [37,[50][51][52][53][54][55][56]. The lower-case characters a and b represent significant differences between conventional and organic rice production, while ns indicates no significant difference.…”

Environmental Life Cycle Assessment in Organic and Conventional Rice Farming Systems: Using a Cradle to Farm Gate Approach

et al. 2022

The rising demand for agricultural products and expanding public awareness of environmental friendliness have led to the adoption of the organic farming system rather than the conventional one. The life cycle assessment (LCA) concept is a frequently used method to examine the environmental impacts of any activity across its entire life cycle. This research is the first use of LCA for the impacts of vermicompost and cattle manure as organic fertilizers in rice farming. The main goal of this study was to compare the environmental impacts of conventional and organic rice farming. This paper uses midpoint attributional LCA to analyze environmental damages during rice production. The four primary harm categories used in this strategy to categorize the environmental effects were: (1) climate change, (2) human health, (3) ecosystem quality, and (4) resources. The inventory data for the agricultural stage were obtained through farmer interviews. The system boundaries were set to cradle to farm gate, and 1 ton of final product (dry matter) was used as the functional unit. The results show that in all main damage categories, except for particulate matter formation, stratospheric ozone depletion, mineral resource scarcity, and freshwater eutrophication, conventional rice production has higher environmental impacts than organic rice production. Overall, organic rice production is more effective in diminishing the negative environmental effects of farming compared to conventional rice production.

“…However, once a lifecycle assessment is conducted the bene t would become apparent [17,74]. The concept of life cycle assessment concept refers to the process of evaluating the environmental impact of an investment or a process during its anticipated duration of operation [75]. Based on the life cycle assessment concept it predicted that; H4: Reduce waste management practice leads to higher nancial performance H5: Reuse waste management practice leads to higher nancial performance H6: Recycle waste management practice leads to higher nancial performance.…”

The study conceptually suggested isomorphic pressures as the drivers of sustainable food waste disposal management, and operational performance as an attendant outcome. 400 fast-food restaurant businesses in the metropolitan city of Harare were surveyed using a self-administered questionnaire whose items were distilled from the extant literature. Data analysis was conducted using Structural Equation Modelling (SEM) on an Analysis of Moment Structures (AMOS). The results indicated that the three isomorphic pressures (cohesive, mimetic, and normative) have statistically significant influence on the adoption of sustainable food waste disposal management practices and in turn the same practices lead to profitable operations. The study therefore concluded that the three variants of isomorphic pressure and profitability act as the push and pull strategies for the adoption of sustainable food waste disposal management practices respectively. In terms of policy implications, the study recommended the reinvigoration of various isomorphic pressures related to the food waste disposal management.

Tobacco wildfire disease caused by Pseudomonas syringae pv. tabaci is one of the most destructive foliar bacterial diseases occurring worldwide. However, the effect of wildfire disease on cigar tobacco leaves has not been clarified in detail. In this study, the differences in microbiota and chemical factors between wildfire disease‐infected leaves and healthy leaves were characterized using high‐throughput Illumina sequencing and a continuous‐flow analytical system, respectively. The results demonstrated significant alterations in the structure of the phyllosphere microbial community in response to wildfire disease, and the infection of P. syringae pv. tabaci led to a decrease in bacterial richness and diversity. Furthermore, the content of nicotine, protein, total nitrogen, and Cl− in diseased leaves significantly increased by 47.86%, 17.46%, 20.08%, and 72.77% in comparison to healthy leaves, while the levels of total sugar and reducing sugar decreased by 59.59% and 70.0%, respectively. Notably, the wildfire disease had little effect on the content of starch and K+. Redundancy analysis revealed that Pseudomonas, Staphylococcus, Cladosporium, and Wallemia displayed positive correlations with nicotine, protein, total nitrogen, Cl− and K+ contents, while Pantoea, Erwinia, Sphingomonas, Terrisporobacter, Aspergillus, Alternaria, Sampaiozyma, and Didymella displayed positive correlations with total sugar and reducing sugar contents. Brevibacterium, Brachybacterium, and Janibacter were found to be enriched in diseased leaves, suggesting their potential role in disease suppression. Co‐occurrence network analysis indicated that positive correlations were prevalent in microbial networks, and the bacterial network of healthy tobacco leaves exhibited greater complexity compared to diseased tobacco leaves. This study revealed the impact of wildfire disease on the microbial community and chemical compositions of tobacco leaves and provides new insights for the biological control of tobacco wildfire disease.
