China’s pork sector is a major component of the national food system. Establishing plant-based pork supply chains requires coordination across production, quality control, infrastructure, logistics, information exchange, and market formation. However, previous studies generally examine these barriers separately, limiting understanding of how they interact within the wider food-supply system. This study identifies and analyzes the systemic barriers to establishing plant-based pork supply chains in China. An integrated Fuzzy Delphi Method (FDM) and Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach is applied. FDM is used to refine and validate 14 contextually relevant barriers based on expert consensus, while DEMATEL examines their direct and indirect relationships, systemic prominence, and net causal influence. Insufficient research and development funding and deficiencies in quality control emerge as the strongest net causal barriers. High infrastructure investment also belongs to the cause group, while technological, operational, and market-related barriers occupy different causal and dependent positions within the wider system. The results support a sequenced intervention strategy that begins with innovation capacity, quality assurance, and infrastructure, followed by operational coordination and market formation. This study contributes by moving beyond barrier identification and ranking to explain how multiple barrier domains interact and how interventions can be prioritized. The analysis concerns supply chain establishment and does not directly assess the environmental, economic, or social sustainability performance of plant-based pork. Full article

Livestock production in Africa occurs across highly heterogeneous agroecological and management environments, ranging from extensive pastoral and mixed crop–livestock systems to intensive enterprises. These systems are characterized by seasonal and spatial variation in feed resources, reliance on locally available forage and agricultural by-products, climatic stress, endemic diseases, and the use of indigenous and locally adapted breeds. Such conditions create distinctive microbiome–host interactions that remain poorly represented in global livestock omics research. Although the gut microbiome is central to nutrient utilization, immune function, metabolic homeostasis, and resilience, the functional mechanisms linking microbial communities, diet, host physiology, and productivity in African livestock remain insufficiently characterized. African systems are particularly underrepresented in integrated microbiome–metabolomics datasets, longitudinal studies, and artificial intelligence (AI)-enabled predictive models, limiting the development of context-specific precision nutrition strategies. This review examines the integration of metabolomics and AI with microbiome and host data to advance precision livestock nutrition within an African and One Health context. It identifies both substantial constraints and strategic opportunities. Limited research infrastructure, high-quality regional datasets, computational capacity, and specialized expertise remain major barriers. Conversely, Africa’s diversity of livestock breeds, feed resources, agroecological conditions, and naturally occurring resilience phenotypes provides an important opportunity to identify microbiome–metabolite signatures associated with feed efficiency, disease resilience, climate adaptation, and product quality. Emerging metabolomics and computational capacity, particularly in South Africa, could support regional research networks and continental data infrastructures. Furthermore, the review proposes an Africa-specific approach that develops locally grounded, scalable, and resource-sensitive precision nutrition strategies, strengthening antimicrobial stewardship, animal health, food safety, climate resilience, sustainable livestock production, and broader One Health objectives.

Phosphogypsum (PG), a gypsum-rich by-product of wet-process phosphoric acid production, is increasingly considered for land application because it can supply calcium and sulfur and alleviate constraints such as sodicity, subsoil acidity, and vegetation establishment limitations. However, PG may also contain residual acidity, soluble salts, fluoride, heavy metals, and naturally occurring radionuclides, creating multiple exposure pathways. This critical review distinguishes direct PG evidence from gypsum or sulfate analogue evidence, life cycle assessment/material flow analysis evidence, and risk control studies. It evaluates PG land application according to receiving soil conditions, diagnosed constraints, exposure pathways, and environmental safety boundaries. The strongest evidence supports use in diagnosed sodic and saline–sodic soils, whereas applications in Al-toxic acid subsoils, flooded paddy systems, contaminated or degraded soils, and non-food vegetated systems require conditional assessment. PG should therefore be treated as a context-specific management option rather than an unrestricted disposal route. By linking waste valorization with soil demand, source quality, exposure control, and long-term monitoring, the proposed framework contributes to sustainability by integrating circular resource use with soil health, water protection, food/feed safety, and risk-informed governance, while helping to prevent the transfer of environmental burdens across ecosystems or generations.

In the event of a nuclear or volcanic winter, up to two-thirds of sunlight could be blocked (abrupt sunlight reduction scenarios, ASRS), leading to a worldwide crop failure. There are some similarities between such effects and the short northern summer. This suggests the possibility of transferring successful agricultural practices validated in high latitudes to tropical regions, especially low-tech solutions, which can be more easily implemented in the case of a global catastrophe. We show that equatorial regions’ temperatures under a 150 Tg (millions of tonnes of soot to the stratosphere) scenario of nuclear winter (around 15 °C average) are similar to summer temperatures in northern European regions of the former Soviet Union, which had functional agriculture. We identified the following main agricultural technologies which can be adapted: (a) cold-tolerant crops, first of all potatoes, but also rutabaga and fodder beet; (b) frost-protection technologies (night-covering, watering, bottles with water); (c) silage production in pits for animal feeding; (d) and low-labor-demanding crops. One meta lesson is making several bets on different food-producing technologies in the situation of risky agricultural practices. These findings contribute to Sustainable Development Goal 2 (Zero Hunger) and highlight how historically validated, low-input agricultural knowledge can underpin sustainable food system resilience under extreme climate disruption.

Climate change poses escalating risks to small-scale farmers’ food security across Sub-Saharan Africa (SSA), yet evidence on how adaptation strategies transform into food security outcomes remains fragmented and unevenly distributed. This study systematically reviewed 66 peer-reviewed studies retrieved from various databases including Sabinet African Journals, Web of Science and PubAg. The peer-reviewed studies were obtained through following PRISMA guidelines which involve searching criteria (using key words) and screening criteria (applying filters). The aim of this study was to synthesise climate-related challenges, adaptation strategies and policy gaps affecting small-scale farming systems in SSA. Empirical findings indicate that prolonged droughts, rainfall variability and temperature stress dominate climate-related challenges. Small-scale farmers’ adaptation responses cluster around technological and on-farm practices, integrated climate-smart agriculture, livelihood diversification, crop- and livestock-based strategies and knowledge-based interventions. As a result most strategies positively influence the availability, stability and access pillars of food security. However, adaptation effectiveness is strongly constrained by systemic policy gaps, notably weak extension and institutional support, limited access to finance and inputs, affordability and scalability barriers to CSA technologies. These constraints disproportionately affect resource-poor farmers, reinforcing inequalities and limiting the scalability of successful local adaptation. Therefore, strengthening institutional capacity, aligning policies with farmer realities, integrating local knowledge and gender considerations and expanding financial access emerge as central priorities for transforming adaptation efforts into sustained and equitable food security outcomes across SSA.

Agriculture plays a key role in global food production, whereas organic waste management remains an important environmental challenge. Organic residue-derived compost represents a sustainable strategy for nutrient recycling, soil fertility improvement, and reduced reliance on synthetic fertilizers in horticultural systems. This study systematically reviewed the scientific literature on the application of compost in cherry tomato (Solanum lycopersicum var. cerasiforme) cultivation to evaluate its effects on agronomic performance and production systems. A database search from 2004 to July 2025 identified 86 studies that met the predefined eligibility criteria. The analysis showed an increasing trend in research over the last two decades, with publications peaking in 2021. Most studies were conducted in Latin America, particularly in Colombia, Mexico, and Brazil, highlighting the relevance of the cherry tomato crop. The application of compost was associated with improved plant growth, nutrient availability, and crop productivity. The production cycles ranged from 37 to 220 days, with shorter cycles commonly observed in tropical environments. Rice husk compost is among the most frequently used organic amendments. Overall, compost represents an effective strategy to enhance agronomic performance and promote sustainable cherry tomato production worldwide. Full article

Oyster aquaculture plays a critical role in coastal social-ecological systems by providing ecosystem services such as economic benefits, food security, and environmental regulation; however, multiple biophysical and socio-economic stressors threaten its long-term sustainability. This study operationalizes the seven established resilience principles to identify strategies that enhance the resilience of oyster aquaculture globally. A scoping review following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted across Scopus, Web of Science, and JSTOR, yielding 345 peer-reviewed publications (2000–2026) from which 13 stressor categories and 15 mitigation strategy categories were identified. Diseases and pathogens constituted the most documented stressor (24.3%), followed by climate change and ocean acidification (9.9%). Among strategies, the governance, policy, and stakeholder engagement strategy was the most frequently used (12.8%). Classification by resilience principles revealed that managing slow variables and feedback (P3, 30.1%) and maintaining diversity and redundancy (P1, 22.6%) dominated the literature, while broadening participation (P6, 11.0%) and promoting polycentric governance (P7, 4.6%) were least represented, revealing a significant gap in the scientific literature between biophysical and socio-institutional research attention. Context-specific indicators were developed for each principle, providing a replicable framework linking stressors, strategies, and resilience principles applicable to diverse mariculture systems.

In this review, I synthesize recent evidence showing how climate acceleration, biosphere disruption, food and freshwater insecurity, pollution, disease, and inequality are increasingly converging into a single, interconnected sustainability challenge. I show that the Anthropocene crisis extends far beyond climate warming and its impacts alone: current national commitments remain consistent with warming of approximately 2.3–2.5 °C under full implementation, while current policies could produce up to 2.8 °C; however, the remaining carbon budget for a 50% chance of limiting warming to 1.5 °C may be exhausted within only a few years, and the oil and gas industry has committed to a 14% increase in upstream production over the period 2024–2030. At the same time, pollution remains responsible for approximately nine million deaths annually; agriculture accounts for roughly 70% of global freshwater withdrawals; and groundwater depletion, continental drying, marine heatwaves, weakening carbon sinks, and intensifying precipitation extremes are destabilizing the ecological and hydrological systems that sustain human health and food security. This review’s incremental contribution is the integration of these trends within a justice-centered sustainability framework that links Earth-system feedback, public health burdens, water insecurity, and institutional failure rather than treating them as separate environmental problems. I argue that because vulnerability is produced not by exposure alone but by unequal access to infrastructure, wealth, governance capacity, and political power, a viable response therefore requires more than decarbonization: it demands ecological restoration, food and water-centered governance, pollution and disease mitigation, and justice-based institutional reform capable of sustaining human dignity, equity, and resilience within planetary boundaries. I encourage resilience and sustainability programs around the world to fold in these additional challenges to their missions and goals. Full article

Behavioural nudges modify choice architecture to steer food choices without removing alternatives or substantially changing economic incentives. This critical narrative review synthesises 62 sources from behavioural public policy, public health nutrition, food ethics, and sustainable food-system governance. It distinguishes healthy food nudges, sustainable food nudges, green nudges, and responsible food-system interventions, and compares availability, placement, defaults, labels, digital architecture, and mixed policy packages. The evidence shows that nudges influence immediate food selection, but effects are heterogeneous and weaker for sustained environmental outcomes. Price instruments address affordability, nudges address attention and convenience, and boosts strengthen decision competence; none can substitute for the others. Ethical acceptability requires a transparent, calibrated opt-out process, equity monitoring, disclosure of commercial motives, democratic accountability, and integration with structural policy. Public institutions and profit-driven digital platforms therefore require different governance safeguards. Nudges are most defensible as components of coordinated food-system policy rather than stand-alone solutions. Full article

For decades, industrial trans fatty acids (iTFAs) have remained a critical focus of the scientific community, the food industry, and regulatory authorities because of their well-established role in the development of cardiovascular diseases, metabolic disorders, and chronic systemic inflammation. Rather than providing a descriptive overview, this review critically synthesizes current evidence on the elimination of industrial TFAs by integrating health, technological, regulatory, and sustainability perspectives into a comprehensive interdisciplinary analysis. The review outlines the biochemical characteristics and dietary sources of trans fatty acid isomers, highlighting the continuing scientific debate regarding the differential health effects of industrially produced and naturally occurring ruminant-derived TFAs. It also examines the evolution of scientific evidence that led to major regulatory actions by international organizations, including the World Health Organization (WHO) and the European Commission, resulting in legally binding restrictions that have substantially reduced industrial TFA intake and improved public health. Particular emphasis is placed on the critical assessment of current fat reformulation strategies, considering not only their technological functionality but also their nutritional quality, long-term metabolic implications, and contribution to sustainable food systems. Full hydrogenation, fractionation, chemical and enzymatic interesterification, and oleogelation are comparatively evaluated with respect to their advantages, limitations, and potential technological, nutritional, and environmental trade-offs. In addition, lipid microencapsulation is discussed as an emerging strategy for protecting oxidation-sensitive polyunsaturated fatty acids (PUFAs), thereby facilitating their incorporation into functional foods while maintaining nutritional quality. Unlike previous reviews that primarily focus on health outcomes or individual processing technologies, this review systematically integrates the sustainability dimensions of alternative fat modification approaches, including resource efficiency, energy consumption, clean label product development, and circular economy principles. Furthermore, it identifies current knowledge gaps related to the long-term metabolic safety, industrial scalability, and environmental performance of emerging lipid technologies. By combining these complementary perspectives, the review provides a comprehensive interdisciplinary synthesis that supports evidence-based fat reformulation and offers practical guidance for researchers, food manufacturers, and policy makers seeking to develop safer, nutritionally improved, technologically functional, and environmentally sustainable lipid systems.

This scoping review synthesizes 35 studies on sensor technologies and artificial intelligence for fruit detection, classification, and quality assessment, contrasting Latin American and international research traditions. The analysis suggests notable differences in technological approaches between the included Latin American and international studies: Latin American research tends to emphasize in developing accessible, practical solutions using classical computer vision and low-cost hardware, while international studies more frequently employ through deep learning architectures, multi-modal sensing, and complete robotic automation systems. Across the included studies, relatively limited attention was given to AI-assisted decision support for agricultural practitioners, insufficient consideration of inclusivity, and the scarce integration of environmental sustainability into intelligent sensing system design. The review identifies that only 8 of 35 studies originate from Latin America, suggesting an uneven geographical distribution of the available evidence. The included studies generally reported high accuracy values, yet these findings must be interpreted with caution given the reliance on curated datasets that may not represent real-world variability. The reviewed evidence suggests that future research may benefit not from one approach dominating the other, but from a thoughtful integration of complementary strategies, including knowledge transfer, edge computing democratization, and human-centered design. Overall, this review suggests that the ultimate goal extends beyond accuracy metrics to the transformation of agricultural practices that enhance food security, economic development, and environmental sustainability across the global agricultural landscape. It is important to note that this work does not propose or validate a new fruit detection algorithm but rather synthesizes and critically evaluates existing scientific evidence regarding sensor technologies and artificial intelligence applied to fruit detection and quality assessment.

Global food systems must balance productivity with environmental sustainability amid climate change, geopolitical shocks, and unevenly distributed natural resources. This study introduces the Food Supply Sustainability Index (FSSI), a transparent, composite measure of the sustainability of a nation’s food production including international trade, and future climate-driven trade dynamics, with a distance-to-target method. Using FAO and IFPRI data, the FSSI categorises countries into five sustainability classes across three pillars: carbon footprint, soil degradation, and water stress. The results show high-income countries produce food less sustainably, while low-income countries do so more sustainably yet are more vulnerable to climate change and trade disruptions. The FSSI therefore recognises that trade redistributes rather than removes environmental risk, creating a more evenly distributed yet persistent global vulnerability to shocks. Under future climate scenarios, the index identifies that sustainability worsens in poorer regions, especially Sub-Saharan Africa, exposing countries to food insecurity. By combining multiple environmental dimensions into a single metric, the FSSI enables countries to benchmark sustainability performance and identify priority areas for intervention. The FSSI supports policies such as aligning imports with sustainability criteria, diversifying suppliers toward lower-impact origins, and supporting sustainable intensification in low-income settings. The FSSI provides a replicable, policy-relevant tool to assess, compare, and communicate global food system sustainability. Full article

Objective: To synthesise contemporary Australian evidence on how local governments act to support healthier, sustainable and equitable food environments, and to examine the governance arrangements, policy and planning levers, monitoring practices, and implementation conditions shaping local action. Methods: A rapid review of peer-reviewed and grey literature published between January 2015 and February 2026 was performed. Searches were conducted in Medline Complete, CINAHL Complete, Health Policy Reference Centre and Scopus, alongside structured grey literature searches. Included documents addressed Australian LG food environment roles, policies, planning, governance, or monitoring. Findings were narratively synthesised and mapped to national research priorities. Results: Thirty-eight documents were included (23 peer-reviewed studies and 15 grey literature reports). Evidence clustered most strongly around food systems and food security, governance and multisectoral partnerships, and food environment monitoring, particularly food access profiling, affordability monitoring and mapping activities. In contrast, the extent of coverage on statutory planning mechanisms, formal regulatory powers, and consumer behaviour outcomes was limited. Reports of evaluated interventions were concentrated in bounded organisational settings where councils held clearer jurisdiction, such as sport and recreation facilities. Across contexts, LGs were commonly positioned as convenors, brokers and enablers operating within constrained mandates and fragmented multi-level governance settings. Reported enablers included leadership, dedicated resourcing, partnerships and access to local data; common barriers included limited statutory authority, short-term funding and weak vertical policy integration. Conclusions: Australian local governments are active food system actors, but stronger statutory integration, clearer decision pathways, and more consistent monitoring and evaluation are needed to translate local activity into sustained improvements in healthy, sustainable and equitable food environments.

Balancing food production, ecosystem service value, and agricultural irrigation water consumption is a major challenge for sustainable agricultural development in China. However, quantitative evidence at the national scale remains limited on whether crop planting structure optimization derived from models can effectively achieve coordination among these three objectives. Existing studies mainly focus on individual crops or localized regions and rarely integrate the spatiotemporal evolution, influencing factors, and multi-objective optimization of major staple crops within a unified framework. This study developed a progressive framework integrating spatiotemporal evolution analysis, influencing factor identification, and planting structure optimization for wheat, rice, and maize. Spatial autocorrelation analysis, center-of-gravity shift analysis, and pixel-based image differencing were applied to reveal crop evolution patterns across China from 2000 to 2025. A five-dimensional indicator system comprising 17 quantitative indicators was developed through multiple experiments using four large language models, and the Random Forest algorithm was employed to identify key influencing factors and their relative importance. Based on these factors, optimization constraints were constructed, and a multi-objective fuzzy linear programming model combined with the NSGA-II algorithm was used to determine optimal crop area allocation across 28 provincial-level regions. The three staple crops exhibited a significant pattern of northward shift, eastward expansion, and southern contraction. Precipitation and market accessibility were common core influencing factors, ranking among the top five factors in all nine Random Forest models. Crop-specific factors, including soil available phosphorus for rice, accumulated active temperature for wheat, and soil pH for maize, explained differences in spatial responses among crops and provided a scientific basis for optimization modeling and coordinated improvement of food production, ecosystem service value, and irrigation water consumption. The optimized scheme increased total grain output by 3.6%, improved ecosystem service value by 11.0%, and reduced irrigation water consumption by 45.7% compared with the actual planting structure, all 28 provinces achieved improvement or stability in the three indicators simultaneously. Based on optimized crop allocation patterns, national planting structures were summarized into regional models, including a rice–maize dual-core system in Northeast China, wheat–maize rotation in the Huang-Huai-Hai Plain, rice-dominated systems in the middle and lower Yangtze River Basin and South China, water-efficient dryland farming in Northwest China, and a diversified balanced system in Southwest China. These findings provide a quantitative reference for optimizing China’s staple crop planting structure. Full article

The sustainability of Coffea arabica L. production in Oaxaca, Mexico, is increasingly threatened by climate change, biodiversity loss, and pest pressure, along with other factors that undermine the responsiveness of small-scale producers in the state, such as trade restrictions and coffee-related regulatory frameworks. These challenges are particularly acute in mountainous regions like Oaxaca, where coffee cultivation plays a central role in rural livelihoods, cultural identity, and territorial development. Studies demonstrate that localized models are vital for rural improvement, reducing the carbon footprint, and maintaining economic viability. Despite extensive research on agronomic, environmental, and market factors, sustainability strategies for coffee production often remain fragmented and insufficiently integrated. This systematic review used the Scopus Review database, searching by title, abstract, and keywords such as “sustainable coffee production” from 2015 to 2026. A total of 1085 documents were retrieved and processed using VOSviewer software to generate a bibliographic map in which frequently used words are grouped by color to show their relationships. Using Oaxaca as a regional case study, the article synthesizes the key factors influencing coffee productivity and quality, examines the main socio-environmental challenges, and proposes a conceptual framework that integrates agroecosystem management with socioeconomic processes under external climate and market pressures. The proposed framework highlights the central role of agroforestry systems and ecosystem services in improving climate resilience, conserving biodiversity, and supporting quality-oriented value chains. These processes generate feedback loops that influence farmers’ livelihoods, food security, and territorial sustainability. While grounded in the context of Oaxaca, the socio-ecological review and conceptual framework presented here are applicable to other Arabica-producing regions facing similar challenges, providing a structured basis for future research, policy design, and integrated sustainability strategies.
