As part of food systems, aquatic foods provide nutritious, affordable, convenient options for healthy diets, and can also foster sustainable food production. Within the food system framework, the food environment is the space that connects food procurement to consumption. The food environment influences consumer decisions on which foods to acquire. To date there has been relatively little focus on creating an enabling food environment that supports consumers in decisions to obtain aquatic foods. To fill this gap, we conducted a narrative review of literature from 2000–2020 to document the availability, affordability, convenience, promotion, quality and sustainability of aquatic foods within diverse food environments. Our review highlighted several opportunities that can support development and promotion of convenient, high quality aquatic foods. We also noted several research gaps. For example, some consumers, especially those in high income countries, respond well to labels related to sustainability and also to messaging to consume diverse types of fish, especially lower tropic species like anchovy. However, less is documented on how promotion influences consumers from LMIC. The paper also notes a gap in assessment of the price and affordability of aquatic foods. Most price and affordability assessments do not provide details on which aquatic foods were considered in the costing assessment. In addition, wild or home-harvested aquatic foods are often not accounted for in price and affordability assessments. Using case studies, we demonstrate how considering the food environment in research and implementation strategies can add value to program design. For example, processing tuna frames and underutilized small fish species into powder is one innovation that reduces food waste and also creates a convenient, quality product. These results provide the foundation for deepening our understanding of how key elements of the food environment influence consumers’ decision-making and how these elements can be considered in future research, programming and policy efforts.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"223 4","pages":""},"PeriodicalIF":4.7,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139145303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollination was performed on the same day of spathe opening, as well as up to 16 days after the initial opening. Additionally, we utilized 30 palm trees to analyze the effect of daily average temperatures.Our findings reveal that the optimal period for achieving maximum yield and fruit quality falls between the sixth and eighth day following the cracking of the female spathe. Furthermore, we observed that relatively lower temperatures, ranging from 5 to 20°C, promote the formation of parthenocarpic fruits while inhibiting the development of normal fruits. Moreover, the insights gained from investigating these issues could have broader implications for date palm cultivation in arid regions and offer valuable lessons for the preservation of oasis ecosystems worldwide.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"8 38","pages":""},"PeriodicalIF":4.7,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138994172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding regional climatic variability helps reduce climate risks and ensure food security. This research examined monthly, seasonal, and yearly temperature, rainfall, and relative humidity in Bangladesh using data from 35 meteorological stations from 1970–2020. The study utilized the Mann–Kendall method to evaluate trends and employed Sen’s slope to quantify their magnitude. Additionally, quantile regression was applied to analyze the impact of climatic variables on rice yield. The findings revealed that maximum (Tmax) and minimum (Tmin) temperatures were steadily increasing, with the southwest experiencing a more rapid rise compared to other regions in Bangladesh. Seasonal Tmax and Tmin rose in most parts of Bangladesh, particularly during the monsoon. In most areas, there was a significant (p < 0.05) increase in Tmax from June to September and Tmin in December. The variability of minimum temperature was considerably affected by warming throughout the country. The eastern area had the most significant (p < 0.05) annual rainfall increase rate, while the northern region had the lowest. There was evidence of inter-seasonal rainfall shipment, with post-monsoon rainfall rising compared to monsoon season. The quantile regression showed that the rice yield of Aus (summer) and Aman (wet) seasons were influenced by maximum temperature and relative humidity, whereas the rice yield of the Boro (dry) season was affected by maximum temperature, rainfall, and relative humidity. Across geographical segmentation, the regression analysis indicated a high level of variability in the northern climate. Overall, the intensity of mean temperature increased throughout the country. So, there is a need to develop heat or drought-resistant rice varieties and modernized irrigation facilities to mitigate these climate risks. However, farmers should employ automated weather-based advisory services for sustaining rice productivity and food security.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"33 38","pages":""},"PeriodicalIF":4.7,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, there is a lack of studies in Portugal explaining the increased interest but low consumption of organic products.Here, the relationship between (a) intrinsic motivations, extrinsic motivations, knowledge, and self-perception of control regarding pro-environmental behaviors, and (b) consumption of organic products and other related pro-environmental behaviors was explored. To do so, two semi-structured interview focus groups (n = 15 participants) were conducted.Organic product purchase and consumption seem to be driven by intrinsic motivations such as health or environmental concerns. External aspects such as labels and price as well, as personal, and psychological elements like knowledge and self-control, may be attenuating or strengthening the behavior. These findings should be validated in quantitative studies.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"20 6","pages":""},"PeriodicalIF":4.7,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138947196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we show the anaerobic digestion of CCW by syntrophy between bacteria and archaea in an expanded granular sludge bed (EGSB) bioreactor as a low-cost alternative for bioremediation and biofuel production. The performance of the EGSB bioreactor and the composition of the natural microbial community were evaluated. During the operation of the EGSB bioreactor, physicochemical parameters such as alkalinity ratio (0.25), pH (7.5), and temperature (26°C) were attained and maintained, as well as light- and oxygen-free conditions, which favored the metabolism of oxygen-sensitive bacteria and methane-producing archaea (methanogens). Under these conditions, the chemical oxygen demand (COD) removal rate was highly efficient (> 89%). Methane (CH4) was produced from organic matter degradation by a few methanogens, mainly from Methanosaeta spp., and was enhanced by the metabolic interaction between bacteria and archaea. The biochemical methane potential (BMP) was >335 mL CH4/gCOD, indicating that the syntrophic microbial community is very efficient in removing organic matter and CH4 produced from CWW. Our results suggest that CWW could be treated in EGSB bioreactors and used as a sustainable alternative to CH4 production and also provide insights for the design of synthetic microbial communities (SynComs) for bioremediation, biogas production, and other biotechnological processes.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"53 31","pages":""},"PeriodicalIF":4.7,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The marula fruit is rich in nutritional compounds such as vitamins, minerals, organic acids, and amino acids which contribute to the health properties of the final products. These products can be sold informally by locals or developed into commercially viable, export products. The recent domestic and international demand for marula fruit-based products has raised sustainability concerns such as over-harvesting, habitat destruction, and unsustainable production practices. Given these challenges, a responsible and inclusive approach to marula production and consumption is required to meet the nutritional needs and sustainably contribute to the socioeconomic development of these communities. As a result, a scoping review approach was used to map out the literature on the production and consumption of the marula fruit. All reviewed literature explicitly focused on the marula fruit, the responsible use of the marula fruit, and sustainability practices in the production and consumption of marula fruit-based products. Furthermore, this review examined the potential benefits and challenges of expanding the production and consumption of marula products and identified strategies for promoting sustainable practices and equitable distribution of benefits. Despite the challenges in pre-and-postharvest processing, the marula fruit has remained a valuable resource. Thus, the sustainable production and consumption of the marula fruit require a holistic approach that addresses these challenges and promotes sustainable practices and equitable distribution of benefits. Central to this approach is the application of various technologies to establish robust value chains so the marula fruit industry can thrive.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"38 7","pages":""},"PeriodicalIF":4.7,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to examine the efficacy of enhanced freshness formulation (EFF), a hexanal-based formulation containing antioxidants such as geraniol, α-tocopherol and ascorbic acid, on maintaining the bioactive compounds of gold kiwifruit (cv. ‘Y368’) harvested at two maturity stages. Kiwifruits were treated with three treatments, namely, control (untreated fruit), 0.01 and 0.02% (v/v) EFF. Fruits were treated with 8 weeks of cold storage at 0°C and 90% relative humidity, then transferred to 20°C for 8 days. Three bioactive compounds (ascorbic acid, total phenolics and flavonoids), antioxidant capacities using DPPH and FRAP assays, polyphenol oxidase, ascorbate oxidase, phenylalanine and tyrosine ammonia lyase enzyme activities were evaluated. The results showed that EFF significantly (p < 0.05) influenced bioactive compounds, antioxidant capacities and the activity of enzymes involved in the synthesis and oxidation of bioactive compounds. The maturity stage significantly influenced the content of bioactive compounds. Later harvested kiwifruit had greater content of bioactive compounds, compared to earlier harvested kiwifruit. The total phenolic content was 0.77, 1.09 and 1.22 mg GAE g−1 FW for control, 0.01 and 0.02% EFF, respectively. The FRAP antioxidant concentration was 0.76, 0.91 and 0.96 μmol Fe (II) g−1 FW for control, 0.01 and 0.02% EFF.

Current responses to the growing call for sustainable PO trade are based on environmental impacts such as deforestation, partly because most social impacts have not been studied. These responses are based on information from Asia and South America since little has been done in Africa. This study fills these gaps by synthesizing the impacts of PO trade on ES from peer-reviewed and gray literature. Our case study is Cameroon, which harbors part of the Congo basin forest and experiences fast deforestation rates. Fifty-three sources of literature were used for this study (53% peer-reviewed and 47% gray literature). We found that oil palm cultivation was reported to negatively affect 15 ecosystem services in 147 instances (85%) and positively affect seven ecosystem services in 25 instances (15%). The majority of negative impacts were on carbon sequestration and climate regulation (20%), habitat quality (13%) and genetic diversity (13%). The most positive impact was on food provision (8%). These results highlight the trade-offs between food provision and other ES. While current policy responses have focused on environmental impacts, many negative social impacts are associated with PO trade that should be addressed within new policy tools.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"36 24","pages":""},"PeriodicalIF":4.7,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138952645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a simple and sensitive fluoroimmunoassay (FIA) based on a nanobody-alkaline phosphatase fusion protein (VHHjd8-ALP) and blue-emissive carbon dots (bCDs) was developed for the rapid detection of fenitrothion. The bCDs were synthesized using the one-step hydrothermal method. Citric acid and urea were used as carbon and nitrogen sources, respectively. The synthesized bCDs were characterized by fluorescence spectrum, high-resolution transmission electron microscopy, x-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. After one step of competitive immunoassay, the VHHjd8-ALP bound to the microplate and catalyzed the substrate p-nitrophenylphosphate (pNPP) into p-nitrophenol (pNP); the latter can quench the blue of bCDs due to an inner-filter effect. After condition optimization, an FIA calibration curve was finally created, which showed an IC50 value of 16.25 ng/mL and a limit of detection (LOD) of 0.19 ng/mL. Compared with the pNPP-based one-step conventional indirect competitive enzyme-linked immunoassay (icELISA), the developed FIA showed an 11-fold sensitivity improvement. Furthermore, the analysis period of FIA only takes approximately 55 min, which was obviously faster than that of the conventional icELISA. The recovery test showed recoveries from 81.8 to 119% with fruits and vegetable samples, which verified the practicability and accuracy of the developed FIA.","PeriodicalId":36666,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"135 45","pages":""},"PeriodicalIF":4.7,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138953370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
