  • Evaluation of the effect of jasmonic acid elicitation on composition of
           pigments and biological activities in green callus of neem (Azadirachta
           indica)

    • Authors: Nurul Syazwani Ahmad Fauzi, Muhamad Hafiz Abd Rahim, Nazia Abdul Majid, Rashidi Othman, Jamilah Syafawati Yaacob
      Abstract: This study was carried out with the aim of determining the effects of jasmonic acid (JA) elicitation on the bioactive pigments' biosynthesis and the antioxidant activities in green callus of Azadirachta indica of two different ages (4- and 8-week-old). Plant tissue culture technique was employed to induce the formation of green callus from leaf explants of A. indica on Murashige and Skoog (MS) medium supplemented with 0.6 mg/L thidiazuron (CM) and three different concentrations of JA (2, 4, and 6 mg/L). The methanolic extracts from the green callus were used for determination of total chlorophyll content (TCh), total carotenoid content (TC), total anthocyanin content (TAC), total phenolic content (TPC), and total flavonoid content (TFC) through colorimetric and HPLC analyses. The highest amount of yield was obtained from CM and 2 mg/L JA (2JA) extracts for 4- and 8-week-old samples, respectively. Phytochemical screening revealed the presence of alkaloids, flavonoids, phenols, tannins, and terpenoids in all 4- and 8-week-old samples elicited with 2, 4 and 6 mg/L JA. The highest value for TAC, TCh, TC, TPC, and TFC of 4- and 8-week-old samples were from callus cultured on media supplemented with 6 mg/L JA (6JA) and 4 mg/L JA (4JA), respectively. The lowest IC50 values were found to be 8.29 ± 0.10 mg/mL (6JA) for 4-week-old and 7.73 ± 0.03 mg/mL (4JA) for 8-week-old samples. The highest Ferric Reducing Antioxidant Power (FRAP) values obtained in this study were 90.60 ± 1.55 g/g (6JA), and 74.59 ± 3.91 g/g (4JA), respectively, for 4- and 8-week-old samples. Moreover, Pearson's correlation analysis revealed a significant correlation between TAC, TCh, TC, TPC, and TFC with ABTS and FRAP assays. In addition, PCA analysis revealed that 83.5% of the information (variances) contained in the data were retained by the first two principal components. Overall, these findings suggested that JA supplementation into the culture media significantly increase the chlorophyll, carotenoid, anthocyanin, phenolic and flavonoid contents and JA concentrations at 6 mg/L JA and 4 mg/L JA yielded the highest pigments content in 4- and 8-weeks-old callus, respectively.

  • Production of pigments by Monascus ruber CCT0302 in culture media
           containing maltose as substrate

    • Authors: Camila Fernanda Dias Oliveira, Lígia Alves da Costa Cardoso, Francielo Vendruscolo
      Abstract: The aim of this study was to show how maltose production residues can be used to obtain natural pigments by Monascus ruber CCT 3802 in solid and submerged cultures. The microbial growth and the colour and heat stability characteristics of the pigments produced in both solid and submerged media, with different maltose syrup concentrations, were determined. The results showed that the addition of maltose provided significant increases in the velocity of microbial growth and production of red pigments. The highest radial growth velocity of Monascus ruber (0.1053 mm h−1) was obtained when cultivated in a medium containing 5 g L−1 of maltose syrup, corresponding to a 71.7% increase in growth as compared to the growth velocity in the control medium. Using submerged fermentation, the culture medium containing 10 g L−1 of maltose syrup provided the greatest concentrations of red pigments (14.54 AU510nm g−1 dry biomass) with an intense dark red colour, showing that Monascus ruber CCT 3802 had the capacity to assimilate the substrate and produce pigments. The red pigments produced in the cultures showed good heat stability with activation energies of 13.735 Kcal mol−1.

  • Traditional ecological knowledge to traditional foods: The path to
           maintaining food sovereignty in Hutsulshchyna

    • Authors: Nina M. Fontana, Mariia V. Pasailiuk, Oleh Pohribnyi
      Abstract: The various ecosystems of the Carpathian Mountains spanning Europe, are a rich refuge for culturally important, endemic plant species as well as large carnivores. These biologically diverse landscapes are a principal source of subsistence to 16 million people, including various ethnographic groups. This paper focuses on a case study involving Hutsul communities, an ethnographic group of traditional pastoral highlanders, in the Southeastern Carpathian Mountains of Ukraine. Given ecosystem, climatic, and cultural challenges, especially the rise of illegal logging, commercial harvesting, increased frequencies of flooding, and now a war, Hutsul communities face extensive threats to maintaining socio-ecological resilience in the region. A contributing factor to the region's centuries-long resilience is traditional ecological knowledge upholding food sovereignty as seen through traditional foods derived from Carpathian Mountain ecosystems. Traditional ecological knowledge (TEK) is as a dynamic, generationally-held knowledge base, where language, gathering practices, landscape and culture inform livelihoods. In this article, we seek to answer the following series of questions within Hutsul communities: (1) What does TEK look like in the region' (2) What are the regional environmental challenges' (3) Given these challenges, what are coping mechanisms and adaptive strategies grounded in TEK, ensuring a resilient food sovereign system' Mixed methodologies guided by community-based participatory action research methods (CBPAR) between 2017 and 2019 provide a rich, context-driven perspective on regional TEK. Radiating out from the historical, cultural Hutsul capital, Verkhovyna, 40 experts (including knowledge holders, elders, foresters, and community members) were interviewed in 8 neighboring villages. We, along with Hutsul experts, explore the presence of traditional ecological knowledge (TEK) in Hutsulshchyna by identifying 108 culturally important species including wild plants (74 species), cultivated plants (23 species), fungi (9 species) and lichens (2 species); these species are gathered in 10 habitats with varying degrees of human interaction. We analyze species' presence in traditional foods in the past and present day, as well as contextualize regional environmental challenges impacting TEK practices, and responses to these challenges (coping mechanisms and adaptive strategies). Despite various regional challenges, we conclude that TEK provides a resilient foundation for supporting food sovereignty as seen through the presence of traditional foods.

  • Diversity of growth performance and rumen microbiota vary with feed types

    • Authors: Shuai Du, Zhenkun Bu, Sihan You, Jian Bao, Yushan Jia
      Abstract: Diet is a major factor in influencing the growth performance and the microbial community of lambs. This study aimed to investigate how diverse diets influence their growth performance and rumen microbiota. Ninety male lambs were randomly allocated into three groups in a completely randomized design with equal lambs: non-pelleted native grass hay (HA) as the control diet and pelleted native grass hay (GP) and pelleted native grass hay with concentrate (GPC) as experimental diets. The rumen fluid samples of the lambs in the HA, GP, and GPC groups were used to study rumen microbiota diversity through 16S rDNA high-throughput sequencing. In the present study, the final body weight, dry matter intake, and average daily gain differed significantly (p < 0.05) among the HA, GP, and GPC groups. Compared to the HA group, higher final body weight, dry matter intake, and average daily gain were found in the GP group. Similarly, better animal performance was observed in the GPC group than in the GP group. The principal coordinates analysis displayed that the composition of the rumen microbiota in the three groups was distinctly separated from each other. Bacteroidetes and Firmicutes were the dominant members of the community in the HA and GP groups, while Bacteroidetes, Firmicutes, and Proteobacteria became the predominant members in the GPC group. The comparison among these groups showed significant (p < 0.05) differences in Rikenellaceae_RC9_gut_group, Prevotella_1, Ruminococcaceae_NK4A214_group, and Succiniclasticum. These results suggest that the GP and GPC diets are more beneficial for growth performance than the HA diet and also indicate that the rumen microbiota varied in response to different feed types. In conclusion, these results could provide strategies to influence rumen microbiota for better growth and a healthier ecosystem on the Mongolian Plateau and lay the theoretical groundwork for feeding the pelleted native grass diet.

  • Effects of dietary intake behavior, food supply, nutrition, and health
           during the COVID-19 outbreak

    • Authors: Pantu Kumar Roy, Min Gyu Song, Eun Bi Jeon, So Hee Kim, Shin Young Park
      Abstract: The coronavirus disease 2019 (COVID-19) pandemic, which began in 2019, has far-reaching ramifications, including economic losses and health challenges that still affect various parts of the world. During our review, we learned that the entire world is working to stop the spread of the SARS-CoV-2 outbreak. We explore ways that may lower the danger of SARS-CoV-2 contamination and useful strategies to avoid the possibility of SARS-CoV-2 spreading through food. While hygienic protocols are required in the food supply sector, cleaning, disinfection, and the avoidance of cross-contamination across food categories and other related goods at different stages of the manufacturing process remain especially important because the virus can survive for long periods of time on inert materials such as food packaging. Furthermore, personal hygiene (regular washing and disinfection), wearing gloves and using masks, garments, and footwear dedicated to maintaining hygiene provide on-site safety for food sector personnel, supply chain intermediaries, and consumers. Restrictions imposed in response to the pandemic (e.g., closure of physical workplaces, canteens, cafes, restaurants, schools, and childcare institutions), changes in household grocery shopping frequency, individuals' perceived risk of COVID-19, income losses due to the pandemic, and sociodemographic factors are among the factors. The conclusions drawn from this study consider the implications of healthy diets, food system resilience, behavior change, and nutritional imbalance for policymakers and food supply chain participants, as well as the antimicrobial effects of vitamins and nutrients. During a public health crisis, people should eat less, necessitating preventive policies and nutritional advice to deal with this.

  • Morphological characteristics and biological cycle of the hoverfly
           Eristalinus arvorum (Fabricius, 1787) (Diptera, Syrphidae)

    • Authors: Liang Cao, Qing Zeng, Qiuxia Ren, Aiping Zeng, Yongsheng Zhang
      Abstract: The hoverfly Eristalinus arvorum (Fabricius, 1787) (Diptera: Syrphidae), which belongs to the tribe Eristalini, is well known as a pollinating agent for crops and flowering plants in agricultural and natural ecosystems. Large quantity, wide distribution and their ecological function of the hoverfly E. arvorum make them an appropriate candidate for use as pollinators and environmental indicator species. However, little information has been known on the morphology and the biological cycle of the hoverfly. In this study, feeding experiments under artificial climate chamber and morphological qualitative and quantitative observations were carried out to study the morphology and the biological cycle of the hoverfly E. arvorum. The morphology of eggs, larvae, pupae, and adults of E. arvorum were described in detail for the first time. A complete generation of E. arvorum lasts about 30.12 ± 0.14 days, and there is no significant difference in body length between males (10.27 ± 0.29 mm) and females (11.16 ± 0.45 mm). The most noteworthy morphological features of E. arvorum are the stripes on the compound eyes, the mesonotum, and the abdomen of adults, the chorionic structure consisting of fusiform units on the egg's surface, and the anterior spiracles and pupal spiracles of the pupae. Thus, the detailed description based on morphology and life history will provide the basis for the identification, biodiversity conservation and artificial breeding of the hoverfly E. arvorum.

  • Potential of native and bioprocessed brewers' spent grains as organic soil
           amendments|Introduction|Methods|Results|Discussion

    • Authors: Claudio Cacace, Claudio Cocozza, Andreina Traversa, Rossana Coda, Carlo Giuseppe Rizzello, Erica Pontonio, Francesco De Mastro, Gennaro Brunetti, Michela Verni
      Abstract: IntroductionThe use of novel soil amendments and the exploitation of plant growth-promoting microorganisms are considered promising tools for developing a more sustainable agriculture in times when ensuring high-yield productions with limited resources is essential.MethodsIn this study, the potential of brewers' spent grain (BSG), the major by-product of the brewing industry, as organic soil amendment, was investigated. Bioprocessed BSG, obtained by an enzymatic treatment coupled with fermentation, together with native BSG, were used as amendments in a pot-trial. An integrated analytical approach aimed at assessing the modification of the physicochemical properties of a typical Mediterranean alkaline agricultural soil, and the plant growth-promoting effect on escarole (Cichorium endivia var. Cuartana), was carried out.ResultsThe use of biomasses led to soil organic content and total nitrogen content up to 72 and 42% higher, compared to the unamended soils. Moreover, the lower pH and the higher organic acids content doubled phosphorus availability. Although the number of leaves per plant in escaroles from pots amended with native and bioprocessed BSG did not show any difference compared to plants cultivated on unamended pots, the average fresh weight per escarole head, was higher in pots amended with bioprocessed BSG.DiscussionHence, the results collected so far encourage BSG application for agricultural purpose, while solving the problem of disposing of such abundant side stream.

  • Systematic review and meta-analysis of the growth performance and carcass
           composition of Nile tilapia (Oreochromis niloticus) fed dietary copra
           meal|Introduction|Methodology|Results|Conclusion

    • Authors: Tzodoq Obrero Magbanua, Janice Alano Ragaza
      Abstract: IntroductionNile tilapia (Oreochromis niloticus) is one of the most cultured species in the aquaculture industry. However, its market price is affected by the increasing cost of fishmeal. Plant-based proteins are being used to mitigate the problem.MethodologyThis paper comprehensively quantified the growth performance and carcass composition of Nile tilapia fed copra meal via systematic review and meta-analysis. The literature review and paper selection were done based on the preferred reporting items for systematic reviews and meta-analysis method. The data from peer-reviewed papers that qualified from the inclusion screening criteria such as standard error reporting, feeding period, absence of dietary supplements, tilapia development stage, and crude protein levels were subjected to meta-analysis.ResultsResults showed that growth and feed utilization parameters were significantly different (P ≤ 0.05), favoring the control over the plant-based diets. Moreover, the pooled estimate of carcass composition of fish fed copra meal-based diet was not significantly different with that of fish fed fishmeal-based diet (P> 0.05) except for ash content (P < 0.05). The feeding period, crude protein level, fish development stage, and dietary copra inclusions were subjected to meta-regression analysis due to high and statistically significant I2 values to determine the sources of heterogeneity. The residual I2 values showed that these factors did not affect the heterogeneity of the data presented for copra meal. These effects may be attributed to the nutritional quality of raw materials and other abiotic factors like feed preparation.ConclusionNonetheless, data from meta-analysis using model coefficients revealed that the minimum required levels are 594, 617, and 462 g kg−1 of dietary copra meal are needed for optimum growth performance, feed utilization, and carcass composition of Nile tilapia, respectively. The study showed that systematic review and meta-analysis can be a useful tool in optimizing plant-based diets for aquaculture species.

  • Additive-induced pH determines bacterial community composition and
           metabolome in traditional mustard seed fermented
           products|Introduction|Methods|Results and Discussion

    • Authors: Sudipta Sankar Bora, Samim Dullah, Kuntal Kumar Dey, Dibya Jyoti Hazarika, Unmona Sarmah, Darshana Sharma, Gunajit Goswami, Naorem Romen Singh, Madhumita Barooah
      Abstract: IntroductionKahudi and Kharoli are unique naturally fermented mustard seed products prepared and consumed in the northeastern region of India. The pre-fermentation processing of mustard seeds (soaking, pan-frying, mixing with alkaline or acidic additives, airtight packaging) renders a stringent fermentation environment. The metabolic activities of fermenting bacterial populations yield a myriad of glucosinolate-derived bioactive components which have not been described earlier.MethodsThis present study employed integrated 16S rRNA amplicon sequencing and LC-MS-based metabolomics to elucidate the bacterial diversity and metabolome of the two fermented mustard seed food products.Results and DiscussionUnivariate and multivariate analyses of metabolomics data revealed differential abundances of a few therapeutically-important metabolites viz., sinapine, indole-3-carbinol, γ-linolenic acid in Kahudi, and metabolites viz., β-sitosterol acetate, 3-butylene glucosinolate, erucic acid in Kharoli. A metagenomic investigation involving the 16S rRNA (V3–V4) amplicon sequencing showed the dominance of Firmicutes (99.1 ± 0.18%) in Kahudi, and Firmicutes (79.6 ± 1.92%) and Proteobacteria (20.37 ± 1.94%) in Kharoli. The most abundant genera were Bacillus (88.7 ± 1.67% in Kahudi; 12.5 ± 1.75% in Kharoli) followed by Lysinibacillus (67.1 ± 2.37% in Kharoli; 10.4 ± 1.74% in Kahudi). Members of both these genera are well known for proteolytic and endospore-forming abilities which could have helped in colonizing and thriving in the stringent fermentation environments.

  • Short-term trade-offs of organic matter management strategies for
           smallholder farms

    • Authors: Deous Mary Ekyaligonza, Thaddeo Kahigwa Tibasiima, Phillipp Dietrich, John Patrick Kagorora, Jürgen Kurt Friedel, Michael Eder, Bernhard Freyer
      Abstract: Organic matter management (OMM) strategies such as farmyard manure (FYM) application, legume integration, crop residue incorporation, and alley cropping are recognized for improving soil fertility and crop productivity. However, studies on yield and economics of a combination of such strategies on smallholder farms are generally scarce, yet an understanding of such can enhance adoption. This study analyzed the yield and gross margins of crops grown with OMM strategies in comparison to those grown under inorganic fertilizer application on smallholder farms. Field experiments with five treatments over two short rainy (SR) and two long rainy (LR) seasons were conducted from January 2018 to February 2020 on 10 smallholder farms. The treatments (T) included T1 (control): the inorganic fertilizer application strategy that involved maize monocrop with 50 kg/ha Diammonium phosphate (DAP) application and the OMM strategies (T2-T5). T2: cowpea-maize-bean-maize rotation; T3: cowpea-maize-bean-maize rotation + 2.5 tons/ha FYM; T4: Faidherbia albida alleys + cowpea-maize-bean-maize rotation; and T5: Faidherbia albida alleys + cowpea-maize-bean-maize rotation + 2.5 tons/ha FYM. The maize in T3-T5 was intercropped with Mucuna pruriens. The results indicate that the grain and residue yields in LR were not significantly different among all treatments. The total variable costs, which included monetarized labor and annualized capital costs for the establishment of F. albida were significantly higher under T1 than in T2-T5 during LR2018 and not significantly different from what was observed under T3-T5 in LR2019. The accumulated revenues and gross margins for the four seasons were not significantly different between T1 and the OMM strategies. We conclude that the integration of OMM strategies can give gross margins similar to the 50 kg/ha DAP application. Further, based on the price sensitivity analysis, we conclude that the smallholder farmers could adopt T3 and T4 as the gross margins under these treatments are less affected by grain price fluctuations than in T1, T2, and T5. Since the smallholder farmers can access the planting materials, we recommend the adoption of T3 and T4 on smallholder farms.

  • Understanding the determinants and impact of the adoption of technologies
           for sustainable farming systems in water-scarce areas of
           Bangladesh|Introduction|Methods|Results|Conclusion

    • Authors: Faruque As Sunny, Taonarufaro Tinaye Pemberai Karimanzira, Wenhuan Peng, Md Sadique Rahman, Huang Zuhui
      Abstract: IntroductionBangladesh's quest to achieve sustainable development goals has highlighted the need to enhance resilience against the challenges that interconnected food, energy, and water (FEW) nexus systems faces to support human well-being. The government has decided to promote the adoption of competent and cutting-edge technologies that can significantly contribute to balancing energy and water resource utilization in achieving a more sustainable and climate-smart food production system. Hence, scaled-up adoption of solar-powered irrigation systems and recommended fertilizer dose (SIRFD) applications were proposed. This study, to provide practical policy implications, attempts to identify the determinants and impact of SIRFD adoption in water-scarce areas of Bangladesh.MethodsDeterminants of adoption were analyzed using multinomial logistic regression, and the adoption impact was analyzed using treatment effect models.ResultsThe results revealed that land typology, soil fertility perception, soil water retention, knowledge, environmental awareness, secondary income, close acquaintance adoption, and cash availability significantly influenced adoption decisions. The treatment effect model result indicated that farmers who adopted both technologies could reduce production costs by 1.36% and obtain an 8.92% higher ROI than non-adopters.ConclusionThe study findings suggest that policy interventions on scaling up SIRFD adoption require focusing on knowledge development village-based demonstration activities, group farming models backed by micro-finance, and avoiding launching conflicting schemes.

  • Purchasing behavior in rural areas for food products during the COVID-19
           pandemic|Introduction|Methods|Results and discussion

    • Authors: Gioacchino Pappalardo, Roberta Selvaggi, Michela Pittalà, Claudio Bellia
      Abstract: IntroductionMost previous studies have investigated consumer purchasing behavior for food products in urban areas during the COVID-19 pandemic. In contrast, the present study is one of the very few to investigate consumer purchasing behavior for food products within rural areas.MethodsTo this end, research was conducted in Sicily taking as a case study a rural municipality whose population was subjected to a lockdown regime to contain the spread of the virus. The choice of carrying out the research in a rural rather than an urban area contributed to the emergence of new aspects concerning consumer behavior in rural areas during the COVID-19 emergency.Results and discussionThe research reveals that the amount of money spent on food purchases, as well as the amount of food purchased, increased during the lockdown. In general, the research shows that COVID-19 impacted the purchasing behavior of consumers in rural areas even though they showed a high resilience and adaptation to the health emergency situation caused by the pandemic.

  • Box fermentation and solar drying improve the nutrient composition and
           organoleptic quality of chocolate from cocoa beans

    • Authors: Sandra Obinze, Philippa C. Ojimelukwe, Ben A. Eke
      Abstract: Chocolate is a well-liked and popular food product made from the cocoa bean. The objective of this research was to evaluate the effects of box fermentation and solar drying of cocoa bean on chocolate quality. Fermentation was carried out in a perforated wooden box for 168 h with periodic turning after every 48 h. The succession of microorganisms during fermentation and total microbial count were monitored. Both the fermented and unfermented samples were solar dried. During drying the change in weight of the beans, amount of solar radiation, and ambient wind speed of the atmosphere were measured. The approximate nutrient (crude protein, crude fat, total ash, crude fiber, and carbohydrate) and phytochemical (phenol) contents of the dried cocoa beans were evaluated. Sensory properties of chocolate, produced from the two samples (box fermented and dried as well as unfermented and dried) were compared. The initial temperature of the fermenting cocoa mash was 30°C. It rose to 46°C by the 96th h of fermentation and sharply declined to 38°C by the 120th h. Candida, Pseudomonas and Staphylococcus spp were probable organisms identified with the fermenting mass at the initial stage of the fermentation. Lactic acid bacteria dominated after 72 h. Bacillus spp was also observed until the 168th h. Solar drying of unfermented bean lasted for 4 days, while that of fermented bean lasted for 3 days. Fermentation increased the crude protein, total ash and carbohydrate contents of the cocoa beans. It also improved the appearance, and aroma of chocolate from the cocoa beans.

  • Community gardens as a response to the contradictions of sustainable urban
           policy: Insights from the Swiss cities of Zurich and Lausanne

    • Authors: Ingrid Jahrl, Olivier Ejderyan, Joëlle Salomon Cavin
      Abstract: In this paper we explore how policy discourses on urban sustainability impact the governing of urban food gardening in favoring community gardens. Our main hypothesis is that community gardens better accommodate the tensions created by the discourses of the compact and green city compared to other types of food gardening, especially allotment gardens. In the context of the Swiss cities of Lausanne and Zurich, analysis of policy documents confirms this hypothesis by identifying four frames that orient policies toward favoring community gardening: (i) Adapting green space planning to densification favors community gardening with their modest, flexible and multifunctional design, (ii) Revaluating the role of urban food gardening in urban sustainability represents community gardening as a new multifunctional benchmark, (iii) Reorganizing urban food gardening fosters diversity in gardening opportunities which in turn supports a variety of forms of community gardening, (iv) Justifying urban food gardening through public values and needs supports community gardening with their cost-efficient green space management, lower land management and more active citizen participation. In this vein, urban policymakers continually turn to community gardens as a strategic urban planning tool that gives urban green space greater legitimacy in the wake of the densifying city. Overall, urban food gardens continue to be negotiated between space-related marginalization and socio-political significance serving different needs to urban citizens. This results in the need of a more sophisticated planning approach considering different types of urban gardens related to their location in the built city, associated functions, and user groups.

  • Impacts of humic-based products on the microbial community structure and
           functions toward sustainable agriculture

    • Authors: Rhea Amor Lumactud, Linda Yuya Gorim, Malinda S. Thilakarathna
      Abstract: Humic-based products (HPs) are carbon-rich organic amendments in the forms of extracted humic substances from manure, compost, and raw and extracted forms of lignites, coals and peats. HPs are widely used in agriculture and have beneficial effects on plants. While the agronomic benefits of HPs have been widely reported, information on their impact on the soil microbial community composition and functions is lacking, despite claims made by companies of humic substances as biostimulants. In this review, we explored published research on microbial responses with HPs application in an agronomic context. Although research data are sparse, current results suggest indirect impacts of HPs on microbial community composition and activities. HPs application changes the physico-chemical properties of the soil and influence root exudation, which in turn impact the microbial structure and function of the soil and rhizosphere. Application of HPs to the soil as biostimulants seemed to favor plant/soil beneficial bacterial community composition. HPs impacts on microbial activities that influence soil biogeochemical functioning remain unclear; existing data are also inconsistent and contradictory. The structural properties of HPs caused inconsistencies in their reported impacts on soil properties and plants. The sources of HPs and forms (whether extracted or raw), soil type, geographic location, crop species, and management strategies, among others, affect microbial communities affecting HPs efficacy as biostimulants. A more holistic approach to research encompassing multiple influential factors and leveraging the next-generation sequencing technology is needed to unravel the impacts of HPs on the soil microbiome. Addressing these knowledge gaps facilitates sustainable and efficient use of HPs as organic agricultural amendments reducing the use of chemical fertilizers.

  • Diversification of crops: Assessment of managerial flexibility and
           economic impact on sugarcane medium-sized farms

    • Authors: David Ferreira Lopes Santos, Samara Marques Gomes
      Abstract: The aim of this study is to assess the economic viability of a medium-sized sugarcane farm applying a diversification strategy, including the possibility of managerial flexibility in changing its portfolio over time. There is a theoretical gap in the economic evaluation of diversified production systems in farm space. We assessed one diversified structure for the sugarcane agricultural farm that included land areas dedicated to the rotational cultivation of soybean/corn, corn/peanut, and corn/green manure. We considered the managerial flexibility when replacing sugarcane culture. Primary and secondary data were used based on the agricultural context of São Paulo State, Brazil, where the modal profile of medium-sized producers in the region was defined with the support of technicians from the leading agricultural cooperative and sugarcane suppliers association. The results indicate that the diversification strategy for the investigated context generates: lower financial risk for the farm, higher potential return on investment, and higher economic value added.

  • Critical pedagogy for food systems transformation: Identifying and
           addressing social-justice problems in food systems and society

    • Authors: Patricia Allen, Sean Gillon
      Abstract: Current crises in the food system have amplified and illuminated the need for urgent social change to increase equity and survivability. Global crises such as climate change, environmental degradation, and pandemics increasingly disrupt everyday lives and limit possibilities in the food system. However, the prevalence of these crises has not yet engendered commensurate rethinking on how to address these increasingly evident and desperate social problems. Food and food systems are at the core of survival and food systems issues are deeply intertwined with and inextricable from the structures and operating principles of society itself. Effective and equitable change requires new ways of thinking, ways that are different than those that led to the problems in the first place. This requires identifying, conceptualizing, and addressing social problems through critical inquiry that places social justice at the center in order to render visible and explicit the social injustices in problem causes and consequences, as well as transformative pathways toward social justice. One of the most important domains for this work is that of higher education, an arena in which crucial conceptual thinking can be supported. In this brief article we review why critical pedagogy should be a priority in higher education; discuss critical pedagogy for food systems equity; and illustrate how we apply critical pedagogy in the Food Systems and Society online Master of Science program at Oregon Health & Science University.

  • Yield, phenology and triterpene saponins in Colombian quinoa

    • Authors: Elsa Helena Manjarres Hernández, Ana Cruz Morillo Coronado, Agobardo Cárdenas Chaparro, Claudia Merchán López
      Abstract: Exploring yield, phenology and their relationship with secondary metabolites in seeds provides a fundamental analysis that expands knowledge on the nutritional quality of seeds and the effect on productive potential. This knowledge is fundamental when improving or selecting nutritionally important crops, including Chenopodium quinoa Willd, which has excellent nutritional properties and contributes to global food security. This species contains saponins, a metabolite that imparts a bitter taste and can be highly toxic to consumers in large quantities. Therefore, the identification and selection of genotypes according to their saponin contents and outstanding agronomic characteristics are fundamental objectives for the genetic improvement programs of these species. Therefore, the objective of this research was to evaluate the characteristics of the grain, the phenology and the saponin content of 30 C. quinoa accessions with an aim to select or relate genotypes according to their yield and grain quality. The accessions were sown using randomized complete blocks (RCB) with nine repetitions for each material. Seven FAO-defined descriptors were evaluated to characterize the grain and physiological maturity. Saponin was extracted using microwave, and the quantification was done with high-performance liquid chromatography (HPLC) which a UV-VIS detector at 277 nm wavelength. The accessions were classified according to their phenology: semi-late (56.7%), late (36.7%), and semi-early (3.3%). The total triterpene saponin content varied from 0.018 to 0.537%. The multivariate and cluster analyses formed groups of accessions with good yields (>62.02 g of seeds per plant) and desirable grain morphological characteristics. The more suitable accessions for the production of saponins are Quinoa semiamarga (0.537%), Quinoa peruana (0.412%) and Amarilla de maranganí (0.305%). Quinoa real and Quinoa primavera are more suitable for food products, which can be used as parents in future quinoa genetic improvement programs in Colombia.

  • The social costs of pesticide use in France

    • Authors: Christophe Alliot, Delphine Mc Adams-Marin, Diana Borniotto, Philippe V. Baret
      Abstract: The modern agricultural production system relies heavily on the use of synthetic pesticides, but over the course of recent decades various concerns have been raised on the associated negative externalities touching a variety of dimensions, such as human health and the environment. Yet, the magnitude of those effects is still unclear and data availability is scattered and heterogenous across dimensions, regions, and time. The public sector is called upon to develop and implement strategies to face those externalities and their associated social costs. This study aims to provide an assessment of social costs of pesticides in France in the prospect of an integration to the public budget spending, helping public authorities to identify financial flows of public funding with an impact perspective, within a methodological framework based on the social norms at the core of the public system. The results show that the social costs attributable to synthetic pesticide use in France amounted to 372 million euros, of which environmental costs are estimated at least at 291.5 million euros, health costs at least at 48.5 million euros, regulation at least at 31.9 million euros and public financial support to the sector at least at 0.4 million euros. For comparison, this total value of social costs represents more than 10% of the annual budget in 2017 of the French Ministry of Agriculture and Food (3,587 million euros). The analysis can be used as a monitoring indicator for the implementation of public policies in the context of the growing social and environmental issues they face.
