  • Promoting agri-food systems resilience through ICT in developing countries
           amid COVID-19

    • Authors: GM Monirul Alam, Most Nilufa Khatun, Md Nazirul Islam Sarker, Niraj Prakash Joshi, Humnath Bhandari
      Abstract: An increasing body of literature has demonstrated COVID-19's harmful impact on agri-food systems, which are a major source of livelihood for millions of people worldwide. Information and communication technology (ICT) has been playing an increasing role in enhancing agri-food systems' resilience amid COVID-19. In this study, the PRISMA approach was employed to perform a systematic review of the literature from January 2020 to December 2021 on the overall impact of COVID-19 on agri-food system networks and ICT's role in enhancing agri-food system resilience in developing countries. This study reveals that COVID-19 has posed abundant obstacles to agri-food systems actors, including a lack of inputs, technical support, challenges to selling the product, transportation barriers, and low pricing. These impediments result in insufficient output, unforeseen stock, and revenue loss. COVID-19's restrictions have caused a significant food deficit by disrupting the demand and supply sides of the agri-food system networks. A high number of small-scale farmers have had to deal with food insecurity. As a result of the cumulative effects, actors in the agri-food system are getting less motivated to continue producing. This study also argues that many challenges in the agri-food systems can be overcome using ICTs, including maintaining precise farm management, product marketing, and access to production inputs. To assist stakeholders in coping with, adapting to, and building resilience in the agri-food system networks, this article emphasizes the critical need to turn to and expand the application of advanced agricultural ICTs to meet the world's growing needs for food production and to ensure the resilience and sustainability of farming systems, particularly in the face of a pandemic like COVID-19.

  • Mycotoxin communications: Managing messages for different audiences

    • Authors: John F. Leslie, Jeffery B. Morris, Jaya K. Gurung, Jagger J. W. Harvey, Amare Ayalew, Robert Baker, Guangtao Zhang
      Abstract: Mycotoxins, such as aflatoxins, fumonisins, trichothecenes, and zearalenone, are increasing in visibility as a public health threat through both acute and chronic exposure in food. USAID through its Feed the Future program has sponsored research in Nepal on mycotoxin contamination and the correlated high levels of stunting in children under age five. Communicating about mycotoxins is a complicated matter, as is communicating about any potentially serious economic or health threat that may be difficult to control. Two nominal group workshops in Nepal focused on identifying problems from multiple perspectives and developing potential communication strategies to mitigate the problem and potential concerns about it. Target audiences were identified along with their interests and effective channels to communicate with and within them. The first audience to work with is the government, as it must understand and value the problem and help generate confidence in potential regulatory and mitigation processes. Producers, educators and health professionals are the next audiences to address as they are the most closely involved with the problem. Consumer engagement is last, with a communication goal of sharing information to heighten awareness and minimize unwarranted public concern.

  • Multitrait Pseudomonas sp. isolated from the rhizosphere of Bergenia
           ciliata acts as a growth-promoting bioinoculant for plants

    • Authors: Rahul Thakur, Sudhakar Srivastava, Saurabh Yadav
      Abstract: Multifunctional plant growth-promoting bioinoculants are used to enhance growth, harvest yields, and add economic value to agricultural crops. In this study, such bioinoculant, BC-II-20 (Pseudomonas sp.), was isolated from the rhizospheric soil of a medicinal plant Bergenia ciliata from the Garhwal Himalayas, Uttarakhand, India. After characterization, supplementation with Pseudomonas sp. was used to study growth stimulation in a commercially important medicinal plant, Andrographis paniculata (Kalmegh), and it depicted enhanced physiological growth parameters under controlled conditions. Bacterial seed priming and also supplementation led to early and increased germination and plants displayed better vegetative growth during the entire growth stages. Early initiation of flowers and the appearance of pods occurred in inoculated plants, ultimately leading to the reduction in the life cycle of the plant. At the time of harvesting, there was an increase in the physiological parameters such as shoot length (38%), root length (14%), fresh weight (57%), dry weight (60%), number of panicles, and root branching. Photosynthetic efficiency was also higher, and ultimately, overall plant growth was improved by bacterial inoculation. The eco-friendly and sustainable use of this bioinoculant will provide an alternative to harmful chemical fertilizers and has become increasingly important. In conclusion, we reported a promising bioinoculant having plant growth-promoting traits, which promotes growth and development in A. paniculata and may be applied to other plants also.

  • Understanding the differences in cultivated land protection behaviors
           between smallholders and professional farmers in Hainan Province, China

    • Authors: Tao Xu, Haojie Chen, Yifan Ji, Dan Qiao, Fang Wang
      Abstract: Cultivated land protection and quality improvement have become inevitable requirements for alleviating ecological and environmental pressure and sustainable agricultural development. It is of practical significance to explore the differences and causes of cultivated land protection behaviors (CLPB) between smallholders and professional farmers for formulating targeted protection policies and improving their effectiveness. Based on 422 mango farmers' survey data in Hainan Province, this paper explored the internal and external characteristics between smallholders and professional farmers, and used the Fairlie decomposition method to compare and analyze the sources of differences in farmers' CLPB. The results showed that: (1) the CLPB of smallholders and professional farmers differ significantly; (2) the sources of differences in CLPB between smallholders and professional farmers are different, including differences in internal characteristics and differences in external characteristics; (3) differences in internal characteristics are the main cause of the differences in farmer's CLPB, and the contribution of differences in external characteristics was smaller, of which planting years, annual household income and planting scale are the top three factors. It is suggested that differential protection policies should be designed for smallholders and professional farmers, such as guiding smallholders to carry out large-scale operations and improve their organizational level, encouraging and guiding professional farmers to sign long-term contracts to stabilize the land tenure, and formulating subsidy policies for cultivated land protection.

  • Taboos, food avoidances, and diseases: Local epistemologies of health
           among Coastal Endenese in Eastern Indonesia

    • Authors: Victoria Constanza Ramenzoni
      Abstract: To advance interventions targeting malnutrition among small-scale fishing societies, knowledge on the role played by taboos and dietary avoidances on the consumption of fish related products becomes crucial. The article builds upon ethnographic fieldwork (participant observation, focus groups and interviews), dietary questionnaires (n: 112), and archival research among Coastal Endenese in Eastern Indonesia to understand the role played by taboos and dietary preferences in regulating intake of marine products. Moving beyond binary notions of “good” and “bad” when considering the food-system implications of taboos, it explores how local beliefs about illness and food shape dietary practices that can have concrete consequences for an individual's health. Endenese consider fish as having originated from terrestrial creatures, creating a continuous cycle of movement from land to sea and back. Within this cosmology, food is seen as a medium that can bring about healthy outcomes but also disease. Results emphasize the need to understand taboos and food avoidances within the larger cosmological and religious system but also underscore the changing nature of dietary preferences and values due to market integration processes which may have long-term repercussions on health. This information is key to the design of culturally sensitive dietary strategies and alternative livelihoods approaches that seek to minimize poverty.

  • Landscape composition and configuration relatively affect invasive pest
           and its associator across multiple spatial scales

    • Authors: Zhi Wen, Quanfeng Yang, Binbin Huang, Lu Zhang, Hua Zheng, Yusheng Shen, Yanzheng Yang, Zhiyun Ouyang, Ruonan Li
      Abstract: Landscape structures affect pests, depending on compositional heterogeneity (the number and proportions of different habitats), configurational heterogeneity (spatial arrangement of habitats), and spatial scales. However, there is limited information on the relative effects of compositional and configurational heterogeneity on invasive pests and their associates (species that can benefit from invasive pests), and how they vary across spatial scales. In this study, we assayed the invasive pest Bactrocera dorsalis (Hendel) and its associated fly Drosophila melanogaster in 15 landscapes centered on mango orchards. We calculated landscape composition (forest percentage, mango percentage, and Shannon's diversity) and configuration (edge density) using two methods: spatial distance scales and combined scales. Spatial distance scales included buffer rings with radii of 0.5, 1.0, and 1.5 km, and combined scales referred to cutting or not cutting a smaller ring from larger ones. Our results shown that compositional heterogeneity positively affected B. dorsalis and D. melanogaster due to forest cover percentage, whereas configurational heterogeneity with high edge density negative effect on B. dorsalis. Forest cover had less of an effect on B. dorsalis than configurational heterogeneity, but the opposite effect was observed for D. melanogaster. Importantly, the direction and strength of forest cover and configurational heterogeneity to species did not vary with spatial distance scales or spatial combined scales. Thus, compositional and configurational heterogeneity exhibit differential effects on this invasive pest and its associator, and revealed that the relative effects of landscape structures are consistent across multiple scales. These results provide new insights into landscape effects on interconnected species using a diverse spatial-scale approach.

  • Preliminary symbiotic performance of indigenous soybean (Glycine
           max)-nodulating rhizobia from agricultural soils of Tanzania

    • Authors: Monica D. Nakei, Pavithravani B. Venkataramana, Patrick A. Ndakidemi
      Abstract: Globally, the increase in human population continues to threaten the sustainability of agricultural systems. Despite the fast-growing population in Sub-Saharan Africa (SSA) and the efforts in improving the productivity of crops, the increase in the yield of crops per unit area is still not promising. The productivity of crops is primarily constrained by inadequate levels of soil nutrients to support optimum crop growth and development. However, smallholder farmers occasionally use fertilizers, and the amount applied is usually small and does not meet plant requirements. This is due to the unaffordability of the cost of fertilizers, which is enough to suffice the crop requirement. Therefore, there is a need for alternative affordable and effective fertilization methods for sustainable intensification and improvement of the smallholder farming system's productivity. This study was designed to evaluate the symbiotic performance of indigenous soybean nodulating rhizobia in selected agricultural soils of Tanzania. In total, 217 rhizobia isolates were obtained from three agroecological zones, i.e., eastern, northern, and southern highlands. The isolates collected were screened for N2 fixing abilities under in vitro (nitrogen-free medium) and screen house conditions. The results showed varying capabilities of isolates in nitrogen-fixing both under in vitro and screen house conditions. Under in vitro experiment, 22% of soybean rhizobia isolates were identified to have a nitrogen-fixing capability on an N-free medium, with the highest N2-fixing diameter of 1.87 cm. In the screen house pot experiment, results showed that soybean rhizobia isolate significantly (P < 0.001) influenced different plant growth and yield components, where the average shoot dry weight ranged from 2.49 to 10.98 g, shoot length from 41 to 125.27 cm whilst the number of leaves per plant ranged from 20 to 66. Furthermore, rhizobia isolates significantly (P = 0.038) increased root dry weight from 0.574 to 2.17 g. In the case of symbiotic parameters per plant, the number of nodules was in the range of 0.33–22, nodules dry weight (0.001–0.137 g), shoot nitrogen (2.37–4.97%), total nitrogen (53.59–6.72 g), and fixed nitrogen (46.878–0.15 g) per plant. In addition, the results indicated that 51.39% of the tested bacterial isolates in this study were ranked as highly effective in symbiosis, suggesting that they are promising as potential alternative biofertilizers for soybean production in agricultural soils of Tanzania to increase productivity per unit area while reducing production cost.

  • Implementing the nature's contributions framework: A case study based on
           farm typologies in small-scale agroecosystems from the Mexico
           highlands|Introduction|Methods|Results|Discussion

    • Authors: Laura Rodríguez-Bustos, Leopoldo Galicia, Mariana Benítez, Natalia Palacios-Rojas, Irene Ramos
      Abstract: IntroductionIntegrating the heterogeneity of small-scale agriculture with the regulation, material, and non-material contributions is key to complementing the rural-support policy instruments. The objectives of the present study were to analyze the diversity of agricultural types of management in small-scale maize agroecosystems and discuss their implications for nature's contributions in the region of Valles Altos, México.MethodsThe methodology was conducted by constructing an agricultural management typology with multivariate statistical analysis for 112 small plots interviews. The operationalization of regulation, material, and non-material nature's contributions was based on the definition and counting of cultural elements from agronomic management for each class of contribution.ResultsThe results indicate three different types of agricultural management defined mainly by the type of seed, the destination of harvest, and the type of tillage. This management diversity is guided by farmers' motivation to achieve food self-sufficiency or generate income from grain sales. Each management type has a unique provision of regulation, material, and no material contributions defined by the use of the native seed, use of stover, and management diversification.DiscussionThe integration of farm typology methods and nature's contributions framework reveals that it is critical to establish new incentives that include the biological and cultural diversity of agroecosystems and the individual motivations of farmers. This may help conserve the natural and cultural values of agriculture and design appropriate incentives for small-scale agriculture.

  • Achieving the nutrient reduction objective of the Farm to Fork Strategy.
           An assessment of CAP subsidies for precision fertilization and sustainable
           agricultural practices in Germany

    • Authors: Katharine Heyl, Felix Ekardt, Paula Roos, Beatrice Garske
      Abstract: The Farm to Fork Strategy of the EU aims at sustainable food systems. One objective of the Strategy is to reduce nutrient losses by at least 50% resulting in at least 20% less fertilizer use by 2030. To this end, Member States are expected to extend digital precision fertilization and sustainable agricultural practices through the Common Agricultural Policy. In this context, this article applies a qualitative governance analysis which aims to assess the extent to which the measures proposed by the Farm to Fork Strategy, i.e., digital precision fertilization and sustainable agricultural practices, contribute to the nutrient objective of the Farm to Fork Strategy. The article analyses how these measures are implemented through the Common Agricultural Policy in Germany and Saxony. Results show that the nutrient objective of the Farm to Fork Strategy itself offers shortcomings. Germany offers some, yet overall limited, support for sustainable agricultural practices and digital precision fertilization. Hence, the Common Agricultural Policy will to a limited extend only contribute to the objective of the Strategy. The results furthermore highlight some general shortcomings of digitalization as sustainability strategy in the agricultural sector including typical governance issues (rebound and enforcement problems), and point to the advantages of quantity-based policy instruments.

  • Economic viability in the integrated crop-livestock system with nitrogen
           fertilization system and sward canopy heights

    • Authors: Denise Adelaide Gomes Elejalde, André Brugnara Soares, José Donizetti de Lima, Regis Luis Missio, Tangriani Simioni Assmann, Wilson Henrique Tatto, Felipe Luiz Chiamulera Deifeld, Marcos Antônio de Bortolli, Angela Bernardon, Flávia Levinski-Huf, Marcieli Maccari, Pablo Antonio Beltrán Barriga, Anderson Clayton Rhoden
      Abstract: Integrated crop-livestock systems (ICLS) are complex production strategies whose main components are soil, plant, and animal. Several studies addressed the interaction among them and conclude on the technical feasibility of these systems, but few studies assess their economic feasibility. The objective of this work was to analyze the economic feasibility of an ICLS, in which nitrogen was applied on the crop phase or onto the pasture phase, combined with two grazing intensities. The study was carried out on a private farm in the municipality of Abelardo Luz—SC, between October 2012 and April 2018. The experimental design was randomized blocks with three replications. The treatments were arranged in a 2x2 factorial scheme, with two sward heights (high and low) and two times of N-fertilization application, or on the cool-season pasture tillering phase either onto cash crop (200 kg of N ha−1 in a single dose). Crop implementation and maintenance costs were surveyed, followed by crop and livestock production calculations, zootechnical indices, and the revenue of each phase (pasture or grain crop) for the entire system. The cash flow analysis was carried out, generating economic indicators of the three dimensions of the expanded multi-index methodology (MMA) for the system and the treatments. In this study, pasture management with low sward canopy height provided the highest net gains per hectare and per hectare/year, regardless of the nitrogen application time. The use of the ICLS is economically viable, regardless of grazing intensities and nitrogen application times.

  • Remote sensing of hedgerows, windbreaks, and winter cover crops in
           California's Central Coast reveals low adoption but hotspots of use

    • Authors: Jennifer B. Thompson, Jennifer Symonds, Liz Carlisle, Alastair Iles, Daniel S. Karp, Joanna Ory, Timothy M. Bowles
      Abstract: Non-crop vegetation, such as hedgerows and cover crops, are important on-farm diversification practices that support biodiversity and ecosystem services; however, information about their rates and patterns of adoption are scarce. We used satellite and aerial imagery coupled with machine learning classification to map the use of hedgerows/windbreaks and winter cover crops in California's Central Coast, a globally important agricultural area of intensive fresh produce production. We expected that adoption of both practices would be relatively low and unevenly distributed across the landscape, with higher levels of adoption found in marginal farmland and in less intensively cultivated areas where the pressure to remove non-crop vegetation may be lower. Our remote sensing classification revealed that only ~6% of farmland had winter cover crops in 2021 and 0.26% of farmland had hedgerows or windbreaks in 2018. Thirty-seven percent of ranch parcels had cover crops on at least 5% of the ranch while 22% of ranches had at least one hedgerow/windbreak. Nearly 16% of farmland had other annual winter crops, some of which could provide services similar to cover crops; however, 60% of farmland had bare soil over the winter study period, with the remainder of farmland classified as perennial crops or strawberries. Hotspot analysis showed significant areas of adoption of both practices in the hillier regions of all counties. Finally, qualitative interviews revealed that adoption patterns were likely driven by interrelated effects of topography, land values, and farming models, with organic, diversified farms implementing these practices in less ideal, lower-value farmland. This study demonstrates how remote sensing coupled with qualitative research can be used to map and interpret patterns of important diversification practices, with implications for tracking policy interventions and targeting resources to assist farmers motivated to expand adoption.

  • Extrusion parameters and physical transformations of an extrudate for
           fish: Effect of the addition of hydrolyzed protein flour from by-products
           of Oncorhynchus mykiss|Introduction|Methods|Results|Discussion

    • Authors: José Luis Hoyos-Concha, Héctor Samuel Villada-Castillo, Diego Fernando Roa-Acosta, Alejandro Fernández-Quintero, Rodrigo Ortega-Toro
      Abstract: IntroductionThe food industries play a fundamental role in feeding for the functions of animal metabolism. Fish feed extrusion cooking includes process-independent factors such as temperature (°C), screw speed (RPM), throughput, feed, and moisture content that influence the final product's nutritional value and physical properties. The evidence suggests that the application of hydrolyzed protein flour (HPH) is a crucial step for the techno-functional properties of the product. Therefore, this work aimed to study the effect of hydrolyzed protein meal from silage of trout (Oncorhynchus mykiss) on the parameters of the extrusion system and their physical transformations.MethodsIn this study, the influence of hydrolyzed protein meals ranges between 10 and 30% as a substitute for fish meals. The physical properties of the extrudate were monitored, evaluating the hardness, durability, buoyancy, expansion index, and apparent density.ResultsConsistent with this, parameters such as feed composition, screw speed, moisture content, and extrusion process affected the composition and properties of the final product.DiscussionThe physical properties indicated that the hydrolyzed protein flour presented cohesiveness and decreased the mean retention time in the extruder barrel and the specific mechanical energy (SME). Hydrolyzed protein flour during the extrusion process produces pellets with high durability and low hardness due to the high porosity presented, which allows for obtaining nutritional characteristics in the extruded product.

  • Evolution of livelihood vulnerability in rice terrace systems: Evidence
           from households in the Ziquejie terrace system in
           China|Introduction|Methods|Results|Discussion

    • Authors: Chuxiong Deng, Shuyuan Wang, Yaojun Liu, Zhongwu Li, Guangye Zhang, Wenqing Li, Changchang Liu
      Abstract: IntroductionGlobally, terraces, and rice terrace systems face problems that affect their sustainability, such as terrace degradation, abandonment, de-agriculturalization, labor migration, etc. The implementation of development projects such as reforestation, poverty alleviation, and tourism development have changed traditional smallholder livelihood patterns. It is not clear whether farmers' livelihoods have become more resilient or vulnerable as a result.MethodsUsing survey data on households' livelihoods in a rice terrace system in Southern China, we evaluated the livelihood impacts of multiple changes.ResultsThe results show that development projects are not entirely beneficial. The attributes and intensity of the disturbance of projects (e.g., tourism) on land functions, and differentiated farmer strategies jointly drive the hierarchical evolution of livelihood vulnerability. In detail, underdeveloped tourism increased rather than reduced livelihood vulnerability; the role of agriculture in livelihood directly exacerbated the variation in vulnerability levels; this resulted in the most vulnerable livelihood for households that are exogenously dependent or located in the core tourism area.DiscussionSubsequently, an evolutionary model of livelihood vulnerability is proposed in this study. Based on this, we judged that the livelihood vulnerability of rice terrace systems has entered a chaotic stage of adaptation. Reducing livelihood vulnerability will require the support of a tangible and circular pathway of benefits between farmers and the land. Policies should focus on the heterogeneity of farmers and the “negative effects” of development projects on livelihood. This household-level farmer livelihood vulnerability dynamics study goes beyond anti-poverty to provide science-based practical guidance to promote the sustainable development of rice terrace systems.

  • Gender perspectives on coastal and marine ecosystems services flow in
           Kwale County, Kenya|Introduction|Methods|Results|Conclusion

    • Authors: Christine Nyangweso Ochieng, Thuita Thenya, Francis Mwaura, Margaret Awuor Owuor
      Abstract: IntroductionThe continuous flow of ecosystem services (ESs) within coastal and marine ecosystems supports communities' well-being and security by harnessing required resources such as seafood that address food security. The overexploitation of these coastal resources places communities at risk of losing ES. This study assesses how preference for the ES flow from these ecosystem types (i.e., mangrove forests, coastal lagoons, seagrass beds, coral reefs, and the deep sea) vary by gender in Diani Chale and Kisite-Mpunguti Marine Protected Areas in Kwale County, Kenya. Specifically, the objective of this article was to assess the pattern and variation in mean scores of ES flow across coastal and marine ecosystem types by gender.MethodsA total of 148 respondents (87 men and 61 women) aged 20-72 years participated in describing ES through focus group discussions and the Delphi technique. Respondents were engaged in a participatory activity that involved filling of perceived ES flow scores using a 6-point Likert-type scale in the lookup tables (also known as matrix). Data were analyzed using descriptive statistics for mean scores of ES flow across coastal and marine ecosystem types as perceived by men and women. One-way MANOVA was used to test for the significant differences between mean scores of men and women in ES flow across ecosystem types.ResultsThe aggregate scores for non-use values, regulating services, and cultural services, were scored higher than provisioning services by ecosystem service flow. The overall ES flow scores were higher in the mangrove forests 52/90 and least in the coastal lagoon 39/90. There was a significant variation (p < 0.05) of ES flow by gender: the mean score of men was significantly higher than women for most ES flow in cultural, regulating, and provisioning services across some coastal and marine ecosystem types. However, there was no significant variation (p> 0.05) in the flow of non-use values by gender across ET.ConclusionThe findings of this study highlight the importance of understanding gender views in ES access and use at local levels to support food security. Including gender perspectives in coastal and marine ecosystem governance is critical, especially toward achieving sustainable development goals.

  • Nitrogen balance is a predictor of farm business performance in the
           English Farm Business Survey

    • Authors: Clare Gray Betts, Damien Hicks, Mark Reader, Paul Wilson
      Abstract: Global environmental sustainability and food security are fundamental societal issues, and most crop production relies upon inputs from organic or inorganic nitrogen sources. Previous research in the Global North has demonstrated a typical over application of nitrogen across global agriculture with substantial negative impacts on the environment. The objective of this work was to draw on English Farm Business Survey (FBS) data of non-organic General Cropping and Cereal farms to explore the relationship between farm gate nitrogen balance, fertilizer application advice and farm business performance. A mixed effects generalized modeling approach was used to partition the variance into random (such as year, or farm ID) and fixed effects (those of interest). Whilst the financial performance of farm businesses is subject to high variance and multiple drivers, a negative relationship was detected between business performance and farm gate nitrogen balance, we demonstrate that nitrogen lost to the environment of>60 kg per hectare is associated with a significant negative impact on farm performance. Supplier-provided fertilizer advice was also associated with reduced farm performance. These results imply a positive effect on farm performance of enhancing on-farm understanding of crop nutrient requirements through the provision of accredited fertilizer advice. Within the stated bounds our model demonstrates good predictivity on randomly subsetted data, and is presented as a tool for use in scenario modeling of interventions such as agri-environment schemes, Natural Capital and Ecosystems Assessment, and the UN Sustainable Development Goals.

  • Learning from the past to deal with the future: Using different knowledges
           to ensure food security in the Tsá Tué biosphere reserve (Northwest
           Territories, Canada)

    • Authors: Andrew Spring, Michael Neyelle, Walter Bezha, Deborah Simmons, Alison Blay-Palmer
      Abstract: The community of Délı̨nę, located in the UNESCO Tsá Tué Biosphere Reserve, is experiencing the impacts of climate change on the lands surrounding Great Bear Lake, in Northwest Territories, Canada. These impacts are limiting the community's ability to access the land to support their food system, which depends on harvesting traditional foods. This article details a participatory action research approach, driven by the community, that used on-the-land activities, workshops, community meetings and interviews to develop a community food security action plan to deal with the uncertainties of a changing climate on the food system. Data was analyzed using the Community Capitals Framework (CCF) to describe the complex nature of the community's food system in terms of available or depleting capitals, as well as how the impacts of climate change affect these capitals, and the needs identified by the community to aid in adaptation. For Délı̨nę, the theme of self-sufficiency emerged out of concerns that climate change is negatively impacting supplies from the south and that building and maintaining both social and cultural capital are key to achieving food security in an uncertain future. Learning from the past and sharing Traditional Knowledge1was a key element of food security planning. However, other types of knowledge, such as research and monitoring of the health of the land, and building capacity of the community through training, were important aspects of adaptation planning in the community. This knowledge, in its many forms, may assist the community in determining its own direction for achieving food security, and offers a glimpse into food sovereignty in Northern regions.

  • Being with other animals: Transitioning toward sustainable food futures

    • Authors: Joachim Nieuwland, Franck L. B. Meijboom
      Abstract: How do non-human animals (hereafter animals) fit into sustainable food futures' This question prompts ethical reflection. However, especially in times of transformative change, one should not overlook ontological assumptions before engaging in ethics. We follow up on the work of the late Australian philosopher Val Plumwood as she prominently made this move to the ontological level when considering the edibility of animals. As she invites one (1) to listen to animals as well as (2) to embody one's own edibility, salient ontological assumptions about how humans relate to other animals, and the rest of reality, rise to the surface. While Plumwood also developed a modest ethical framework to address animal edibility, her ontological approach is highlighted here, especially as it appears to point toward moral relativism. Plumwood's ontological approach is further developed, notably by unraveling the dualism between self and other. Doing so results in a more non-conceptual way of relating to other animals. As a genuinely interdependent way of engaging with reality, it appears most relevant to considering what role animals might have in sustainable food futures.
