International agri-food trade and climate change interact in ways that have significant implications for supply chain resilience and food sovereignty, yet these interactions remain insufficiently understood at the level of specific traded commodities. This paper analyses European fresh orange imports over 2012–2022 using a unit value decomposition applied to FAOSTAT and Eurostat bilateral trade data, alongside a seasonal supply analysis of monthly import flows from the main exporting regions. The analysis documents a pronounced geographic reorientation of global orange production toward developing and emerging economies in North Africa, Southern Africa, and South America, many of which face documented climate-related stressors. The unit value decomposition identifies how exporter-level unit values and import share reallocations contribute to changes in regional import unit value indices. The seasonal supply analysis shows that the European orange supply depends on a tight sequence of regional exporters operating in largely non-overlapping seasonal windows, leaving limited redundancy if disruptions occur in any single supplying region. These findings provide a descriptive, origin-disaggregated account of Europe’s trade-side exposure in fresh orange supply chains. They underscore the need for product-specific monitoring tools and policy approaches that consider seasonal import dependence, supplier concentration, and the climate vulnerability of major origin regions, while recognising that the present analysis does not estimate causal climate effects.

Sustainable fresh food supply chains depend heavily on effective coordination under uncertain market conditions. Citrus export systems are particularly sensitive to perishability, seasonality, and cold-chain constraints. Under these conditions, reliable price forecasts are important for export planning, logistics efficiency, and sustainable supply-chain management. This study examines the relationship between orange and mandarin export prices in Türkiye using monthly data from 2016 to 2025. Export prices are proxied by real unit values derived from official trade statistics. The analysis applies Augmented Dickey–Fuller tests, Johansen cointegration analysis, and Vector Error Correction Models (VECMs). Forecast performance is evaluated using a rolling-origin framework and compared with ETS, SARIMA, XGBoost, and a seasonal naïve benchmark. The results identify one cointegrating relationship between the two export markets. The estimated long-run coefficient is 0.92, indicating near one-to-one price co-movement. Adjustment toward equilibrium is asymmetric, with orange prices responding faster (ECT = −0.44) than mandarin prices (ECT = −0.21). Forecasting results show that VECM-based models outperform all alternative specifications. The robust VECM achieves the lowest forecast errors (MAPE = 8.3%), compared with 9.8% for XGBoost, 10.6% for SARIMA, 11.5% for ETS, and 14.1% for the seasonal naïve benchmark. Diebold–Mariano tests confirm that these improvements are statistically significant. The findings indicate that orange and mandarin export prices should be analyzed jointly rather than separately. In closely connected citrus supply chains, cointegration-based forecasting models provide more reliable forecasts and a stronger analytical basis for sustainable market coordination. Full article

Amid intensifying extreme climate events, geopolitical conflicts, and sudden trade policy disruptions, the resilience and vulnerability of global staple food trade systems have emerged as pressing governance concerns. This study constructs directed weighted trade networks for wheat, maize, and rice from 2015 to 2024 and evaluates their vulnerability and resilience evolution using a three-dimensional structural resilience framework and underload cascading failure models. The results reveal that all three networks display scale-free and disassortative properties. The wheat network gradually recovered following the Russia–Ukraine conflict, whereas structural imbalance continues to deepen in the maize network, and the rice network faces persistent resilience pressure arising from excessive dependence on core exporters. Cascading failure simulations indicate that targeted attacks on key exporting countries can trigger large-scale network collapse. Introducing cross-crop substitution effects markedly enhances the resilience of individual food trade networks through cross-layer substitution and supplementation; yet under simultaneous attacks, crop substitution effects instead serve as a conduit for cross-layer cascading failure propagation, and even a minimal willingness to substitute can weaken network resilience. Accordingly, this study proposes policy recommendations to strengthen the resilience of the global staple food trade network. Full article

Tomato is one of Thailand’s most significant economic crops, generating substantial export value and serving as a primary source of income for local farmers. However, the traditional manual grading process often fails to comply with the Thai Agricultural Standard TACFS 1503–2007, as grading decisions rely heavily on individual experience and subjective perception, resulting in inconsistent quality. Existing automated systems face the challenges of low accuracy, high costs, and complex hardware, while many are incompatible with Thailand’s grading standards. This study presents a multi-view tomato grading system (MVT-Grader), utilizing a dataset acquired from Doi Kham Food Products Co., Ltd. (Third Royal Factory, Tao Ngoi) under controlled lighting conditions. Subsequently, MVT-Grader is built on a custom-designed lightweight CNN architecture with an adjusted spatially aware loss function to enhance the model’s sensitivity in detecting subtle surface defects and color variations. The proposed model was trained using tomato images captured from two and three different viewpoints via a low-cost webcam setup and processed by a GPU-embedded system. Experiments conducted using stratified 5-fold cross-validation on a real-world industrial dataset demonstrate average grading accuracies of 99.43% (two-view) and 99.64% (three-view). Furthermore, the proposed Real-Time Lightweight CNN with Spatially Aware Loss Optimization achieves processing speeds of 87 ms and 114 ms per tomato for two- and three-view cases, respectively. Compared with MVCNN-Siamese, SDF-ConvNets, and Multi-View Spatial Network, the proposed system outperforms the others in both accuracy and speed, improving accuracy by 1.6–6.11% and reducing processing time by 39–49 ms.

Unsustainable land-use transitions in peri-urban watersheds threaten both food security and ecological integrity. While Patch-generating Land Use Simulation (PLUS) and Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) models for ecosystem service (ES) assessment are commonly integrated, limited studies have simultaneously (i) accounted for multiple real-world spatial policies (e.g., ecological redlines) as hard constraints, (ii) targeted a comprehensive suite of ESs, and (iii) explicitly pursued synergies without relying on large-scale land conversion. To address these gaps, we developed a spatially explicit framework that integrates the PLUS and InVEST models to simulate four land-use scenarios and assess six ESs—grain yield, water yield, nitrogen export, phosphorus export, soil conservation, and carbon sequestration—in the Yuqiao Reservoir watershed, China, during 1990–2030. Against a backdrop of historical declines in cropland/grassland and key ESs due to construction expansion (1990–2020), the novel Comprehensive Development scenario—implementing slope-adaptive management and riparian buffers—synergistically increases grain yield (+0.55%) and carbon sequestration (+1.10%) while drastically reducing phosphorus export (−10.86%). It demonstrates that synergistic gains can arise from strategic spatial reconfiguration within a stable land-use area, advancing a paradigm from area-centric to configuration-centric optimization. This provides a quantifiable methodological basis and actionable policy reference for land spatial optimization in similar water-source watersheds. Full article

OnVeMCS 1.1 is a standalone software for probabilistic human health risk assessment of pollutants in soil, sediment, water, air, and food, enabling Monte Carlo simulation (MCS) of risks across multiple exposure pathways. The hazard index (HI) and cancer risk metrics (TCR/ILCR) for ingestion, inhalation, and dermal contact are quantified using the standard dose/concentration approach. Users can manually enter analyte concentrations with various probability distributions or import them from Excel templates, and select scenario-specific exposure factor sets for residents (children and adults), outdoor and indoor workers, and food consumers. The software supports both one-dimensional (1D) and two-dimensional Monte Carlo simulation (2D MCS) modes. The results are presented through a variety of plots, including histograms and cumulative distribution functions (CDFs), pathway/analyte contribution charts, sensitivity analysis plots, nested CDFs, and uncertainty ribbons. The software also allows the overlay of two or more outputs and the inclusion of regulatory thresholds (HI = 1; TCR/ILCR = 10⁻⁶–10⁻⁴). The results are exported to a multi-sheet Excel workbook containing raw arrays, summary tables, exceedance probabilities, and sensitivity data. OnVeMCS operates quickly, with even 2D MCSs being completed in several seconds. OnVeMCS is distributed as a single Windows installer file with data examples and is free for the academic community.

Sustainable agriculture has been a focus of research for over three decades, gaining particular urgency with the escalation of global conflicts, especially the Russian–Ukrainian war. Selecting appropriate parameters for objectively assessing sustainable agricultural development remains challenging, with limited studies addressing the aggregation of all relevant indicators into a single analytical framework. Given that these indicators and their quantitative values change annually, continuous updating and analysis are essential. This study was guided by selected SALSA/PRISMA principles to structure the indicator-selection process for examining Ukraine’s agricultural sector, which is vital to both national and global food security and accounts for approximately 10% of GDP, more than 50% of exports, and nearly 17% of employment. Alongside climate change pressures, the sector faces severe disruption from military aggression, undermining its economic contribution and stability. This research identifies and selects the most relevant economic, ecological, and social indicators to assess sustainable agricultural development in Ukraine, comparing values before and during the war. Based on these, this study proposes the Sustainable Agriculture Index (ISA), an aggregated measure that integrates multiple dimensions of sustainability. The ISA was calculated using a normalized weighted aggregation approach across economic, environmental, and social indicators. This approach enables a comprehensive evaluation of Ukraine’s agricultural resilience and its capacity to contribute to sustainable development under crisis conditions. Full article

This study examines how Ukrainian enterprises of different size classes adapted their trade activity under the compounded shocks of COVID-19 and the full-scale war. The article addresses national economic resilience and sustainable recovery by examining how export and import dynamics changed among micro-, small-, medium-, and large-sized firms during 2015–2023. The methodology combines the logarithmic decomposition of intensive and extensive trade margins with a strategic positioning matrix based on labour productivity and the net-export coefficient. The results reveal marked size-based differences in aggregate trade-adaptation patterns. During the pandemic, microbusinesses shifted toward a quantity-led compensatory pattern, whereas during the war, medium-sized and large enterprises showed a stronger efficiency-led export pattern. Micro- and small firms displayed characteristics associated with technology-oriented adaptation, combining rapid labour productivity growth with negative trade balances, whereas large enterprises were positioned closer to the niche-exporter profile, supporting the balance of payments but showing signs of slower productivity growth. Medium-sized firms occupied a transformation zone, indicating unresolved adjustment pressure and continued dependence on trade restructuring. These findings suggest that enterprise-size heterogeneity can serve as an analytical basis for differentiated recovery policy. The results are relevant for trade-dependent sectors, including agri-food and food-processing systems, where recovery depends on technological upgrading, export capacity building, and the more effective conversion of imports into future export potential.

The growth in açaí consumption and exports has increased waste generation, particularly from the seed, which accounts for approximately 85% of the fruit mass and is frequently discarded improperly, causing adverse environmental impacts. In this context, the valorization of açaí seeds as a raw material represents a promising and environmentally sustainable alternative. Recent studies indicate that the chemical composition of açaí seeds, characterized by high fiber content and antioxidant compounds, underlies bioactive properties with potential applications across multiple industrial sectors. Therefore, this review aims to provide an overview of the composition and industrial applications of açaí seeds, while identifying current gaps and challenges. Available evidence suggests that incorporating açaí seed flour or extracts into food formulations is promising, although the observed effects are concentration-dependent. In addition, seed-derived extracts have demonstrated biological activities associated with potential health benefits. Furthermore, açaí seeds have potential applications as biochar for soil remediation and as adsorbents in water and wastewater treatment. However, the use of this by-product in packaging materials and in the energy sector still requires further investigation to achieve industrial-scale feasibility. Overall, the valorization of açaí seeds supports more sustainable industrial practices and aligns with circular economy principles. Full article

China plays a multifaceted and pivotal role in the global snake trade network, with its trade dynamics heavily influenced by domestic market demand and international regulatory policies. Based on official CITES trade data from 1975 to 2023, this study systematically analyzes the scale, species composition, source dynamics, and potential risks of China’s legal snake trade by using Whole Organism Equivalents (WOEs) and trade measures adjusted for reporting effort. The results show that the cumulative trade volume exceeded 11.7 million WOEs and that China’s role underwent a major transformation from a “supply center” in the early 1990s to a “consumption hub” by 2012. Export patterns were dominated by colubrid snakes (81.5% of total exports), with the oriental ratsnake (Ptyas mucosa) alone accounting for 56.8%; this reflects a distinctive trade landscape shaped by the domestic culture of “medicine and food homology.” Although the proportion of captive-bred individuals has increased since 2010, a dual-supply system comprising both wild-sourced and captive-bred individuals persists. Furthermore, we identified several misreported species, exemplified by the non-native common cobra Naja naja being recorded as wild-sourced exports from China. Notably, the live venomous snake trade exhibits an extreme geographic concentration, with over 93% of exports directed to Hong Kong, thereby posing significant biosecurity and public health risks. In conclusion, future governance should move beyond simple trade bans by utilizing molecular tools to correct identification biases and by implementing regulatory frameworks modeled on the Hazard Analysis Critical Control Point (HACCP) system. This approach will address biosecurity risks within the trade chain and help achieve a scientifically informed balance between ecological conservation and livelihood security. Full article

Background: Global food supply chains increasingly require sustainable and transparent operations; however, empirical evidence linking sustainability practices to firm performance remains inconsistent. This study examines how sustainability practices are translated into measurable business performance outcomes through traceability implementation in Thailand’s export-oriented food-processing sector. Methods: Grounded in Stakeholder Theory, traceability implementation was conceptualized as an accountability-oriented operational mechanism enabling the systematic verification of sustainability-related activities. Data were collected from 362 export-oriented food-processing firms in Thailand and analyzed using covariance-based Structural Equation Modeling (SEM). Results: The findings indicate that sustainability practices significantly influence both traceability implementation and business performance, while traceability implementation partially mediates the sustainability–performance relationship. The results further suggest that sustainability practices generate both direct and indirect performance benefits through structured monitoring, documentation, and verification routines. Conclusions: This study demonstrates that sustainability practices become more performance-relevant when institutionalized through traceable and verifiable operational processes. The findings highlight the importance of integrating traceability implementation into sustainability strategies to strengthen transparency, stakeholder confidence, and competitiveness within export-oriented food supply chain contexts.

Despite relatively low per capita rice consumption in the European Union (EU), averaging approximately 9 kg annually between 2010 and 2023, imports from Asian countries have shown a sustained upward trend since 2013. This study assessed hazards associated with rice available on the EU market. Data were obtained from Faostat, Eurostat, the Rapid Alert System for Food and Feed (RASFF), and the Web of Science. Pivot tables and a two-way joining cluster analysis were applied to examine temporal and geographical patterns in reported notifications. Notifications primarily concerned genetically modified rice (32%), pesticide residues (21%), and mycotoxins (17%). During 2006–2014, notifications mainly related to unauthorized genetic modifications in rice originating from China and the United States, whereas between 2017 and 2023, they predominantly involved excessive pesticide residues and mycotoxin contamination in rice from India and Pakistan. Most hazards were classified as border rejections (37%), reflecting the effectiveness and vigilance of EU food safety authorities. While rice is generally considered low risk for European consumers, rising cultural integration and the growing popularity of Asian cuisine may increase consumption in the future. Continuous monitoring, rigorous risk assessment, and collaboration with exporting countries are therefore essential to maintain high food safety standards and ensure consumer protection across the EU market.

Despite Morocco’s emergence as the world’s fourth-largest berry exporter, no comprehensive review has evaluated the polyphenol composition, antioxidant properties, and health benefits of raspberries (Rubus idaeus), blackberries (Rubus fruticosus), and blueberries (Vaccinium corymbosum) specifically within the Moroccan cultivation context. This narrative review synthesized evidence from phytochemical analyses, in vitro and in vivo studies, randomized controlled trials (RCTs), meta-analyses, and epidemiological data sourced from PubMed, Scopus, and Web of Science. Blackberries exhibited the highest total polyphenol content (149 μmol GAE/L) and antioxidant capacity, driven primarily by anthocyanin concentration and diversity. Antioxidant mechanisms included free radical scavenging, transition metal chelation, and upregulation of endogenous antioxidant enzymes. Pooled RCT data demonstrated that regular consumption (150–300 g/day) significantly reduced systolic blood pressure (−2.72 mmHg), LDL cholesterol (−0.21 mmol/L), and fasting glucose (−2.70 mg/dL). Additional benefits included neuroprotection via blood-brain barrier crossing and brain-derived neurotrophic factor (BDNF) elevation, prebiotic modulation of Bifidobacterium, Lactobacillus, and Akkermansia populations, and anti-cancer activity via nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) inhibition. Processing significantly affected bioactive retention: freezing preserved phenolic compounds effectively, while conventional drying reduced anthocyanin content by up to 49%. These findings support the integration of Moroccan-cultivated berries—particularly from the Gharb, Loukkos, and Souss-Massa regions—into evidence-based dietary and functional food strategies. Priority research gaps include bioavailability assessment, dose-response characterization, and cultivar-specific phytochemical profiling under Moroccan agro-climatic conditions. Full article

Poland ranks among the world’s leading exporters of goose meat and edible offal, yet domestic consumption remains minimal, revealing a structural imbalance between production and internal demand. This study aims to provide a comprehensive economic assessment of Poland’s foreign trade in goose meat and offal during 2020–2024, examining export specialization, price dynamics, and market resilience. Using official data from the Central Statistical Office (GUS), Eurostat, UN Comtrade, and the National Bank of Poland (NBP), trade flows were disaggregated by CN product codes, destination countries, and unit prices to identify key structural patterns. Results indicate that export volumes remained largely limited by price responsiveness despite sharp price increases and exchange rate fluctuations, confirming stable foreign demand. Exports were heavily concentrated in Germany, which absorbed over 70% of the total trade value, while domestic consumption stayed below 0.5 kg per capita annually. These findings demonstrate both the competitiveness and the fragility of Poland’s export-oriented trade model, characterized by dependence on a single market and limited domestic integration. The study concludes that long-term food system resilience requires diversification of export destinations, stimulation of domestic demand, and stronger alignment with sustainability goals. A forthcoming second part will address environmental impacts and consumer awareness. Full article

Water, energy, and food (WEF) are intricately linked through economic activities in the Yangtze River Delta, creating increasingly strong interdependencies. Tracking the consumption and transfer of the water–energy–food (WEF) nexus across regions and sectors is essential for the synergetic management of these critical resources. To characterize the WEF nexus from both consumption and production ends, this study develops a quantitative accounting framework based on a multi-regional input–output model. The proposed framework integrates direct WEF nexus consumption with embodied consumption driven by final demand and further investigates transfer patterns induced by intermediate inputs. The results indicate that the nexus-oriented consumption between water, energy, and food exceeds individual resource consumption. In particular, food-related water resource consumption in the Service sector in Jiangsu is 28 times that of individual water consumption. The embodied consumption of WEF accounts for 42%, 31%, and 47% of the total consumption, respectively. In particular, the embodied consumption of the WEF nexus caused by urban household consumption in Shanghai is much higher than that in other regions. Manufacturing is the resource-exporting sector, while Agriculture and Construction are the resource-importing sectors. Shanghai is a major resource-importing city, while Zhejiang is a typical resource-exporting city. The results also suggest that Jiangsu–Shanghai and Jiangsu–Anhui are regions with strong connections of WEF nexus transfer, while Agriculture–Manufacturing, Manufacturing–Construction, and Service–Construction are sectors with strong connections. These results highlight the complex interplay between water, energy, and food across the Yangtze River Delta. Given this, this study recommends enhancing resource regulation capabilities and paying attention to strongly correlated regions or sectors. Full article
