Industry 4.0 is speeding up the move to connected, data-driven, and automated production, where the Internet of Things (IoT) enables sensing, communication, and real-time support for decisions. At the same time, rapid growth in industrial IoT studies has led to scattered technologies, architectures, and results. This paper fills this gap through a systematic literature review on IoT for Industry 4.0. It also helps readers compare methods and choose suitable building blocks for real deployments today. We focus on key technologies, integration architectures, application areas, challenges, trends, and reported benefits. Using PRISMA 2020, we searched five major databases (Scopus, MDPI, IEEE Xplore, ScienceDirect, and Web of Science) for 2020–2025 and found 584 records. After removing duplicates and screening, we kept 96 peer-reviewed studies for detailed analysis. Results show that most studies use a layered stack that combines sensing/actuation, industrial networking, data collection pipelines, and analytics across edge, fog, and cloud resources. MQTT, OPC UA, CoAP, LPWAN, and 5G connectivity are often used for communication, while RAMI 4.0, IIRA, and similar layered models guide system design. Many architectures follow an edge–cloud pattern, with growing focus on digital twin/CPS links and security-by-design. Applications are mainly smart manufacturing, predictive maintenance, and logistics, with added work in energy management, Construction 4.0, and agri-food monitoring. The key barriers remain interoperability, data quality and evaluation gaps, cybersecurity risks, legacy integration, and deployment limits. The review points to future work on edge AI/TinyML, deterministic connectivity, scalable digital twins, trusted data sharing, and sustainable industrial IoT. Full article

Background: Childhood obesity is a complex public health issue in which parental perceptions and family dietary behaviors are pivotal. This study assessed the feasibility of the Smart Family lifestyle counseling intervention in Greek primary care. It explored changes in children’s dietary behaviors relative to parental weight perception and Mediterranean diet adherence. Methods: A single-arm pretest–posttest pilot study was conducted in Patras, Greece, from Health4EUKids Joint Action. The intervention consisted of four monthly face-to-face counseling sessions using the Smart Family methodology. In total, 49 parent–child dyads (aged 2–12 years) completed the program. Data collection included child anthropometric measurements, validated food frequency questionnaires, parental perception of child weight status, and parental Mediterranean diet adherence. Results: Parents who underestimated their child’s weight status had significantly higher Mediterranean diet scores than those who overestimated (p = 0.032); those with low adherence tended to overestimate and those with moderate adherence to underestimate. The largest reduction was observed for sweets and desserts (median −2.35 servings/week), with significant reductions in sugar-sweetened beverages, grains and cereals, whole wheat products, and dairy. Fish and vegetable intake increased significantly, but fruit intake did not change. Changes in fast food and red meat differed significantly across Mediterranean diet score tertiles, with larger decreases in the lower tertiles. Conclusions: Smart Family counseling was feasible to deliver through trained healthcare professionals in Greek primary care over four months, with reductions in selected discretionary foods observed alongside the intervention. Parental weight perception and Mediterranean diet adherence emerged as potential barriers to change although the findings are exploratory and require confirmation in a future controlled trial.

Traditional petroleum-based packaging suffers from pollution and functional limits, making it unsuitable for next-generation food systems. In contrast, bio-based smart packaging—combining renewable substrates with responsive components—transforms packaging from a passive shell into an active quality monitor and supply chain information node through three interconnected pillars: renewability, real-time responsiveness to freshness markers, and digital traceability. Market figures confirm this shift, with the smart food packaging sector projected to reach USD 48.97 billion by 2028 (CAGR 4.49% from 2023). This review covers recent progress in natural polymers (cellulose, chitosan, alginate, gelatin) and bio-based polyesters (PLA, PHA). Their multiscale structures enable tunable mechanical and barrier properties while serving as hosts for intelligent functions. Two functional directions stand out: active preservation (antimicrobial, antioxidant, gas-regulating, stimulus-controlled release) and intelligent sensing (colorimetric indicators, bio-based sensors, nano-amplified signals for real-time freshness monitoring). Beyond material functions, digital tools such as IoT and blockchain turn packaging into interactive data nodes, linking material intelligence with full traceability to enhance food safety and supply chain efficiency. Key challenges remain with long-term operational stability, production costs, scalable manufacturing, and life cycle assessments. Nevertheless, bio-based smart packaging is expected to evolve through biomimetic design, process innovation, and system-level integration toward adaptability, multifunctionality, and intelligence, ultimately supporting safer, more transparent, efficient, and sustainable food systems.

Global salinization affects approximately one billion hectares of land in more than 100 countries, posing a severe threat to food security and ecosystem sustainability. Microbial remediation using plant growth-promoting microorganisms offers an eco-friendly alternative to physicochemical methods. However, bridging the gap between laboratory cultivation of single strains and field-scale application of synthetic microbial communities (SynComs) remains difficult, owing to inconsistent efficacy and a lack of unified design frameworks. This review examines the evolution from single strains to rationally designed SynComs for saline soil remediation. A ‘structure–function–mechanism’ framework is proposed, integrating five core microbial modules, namely ion regulation and osmotic stabilization, ethylene and phytohormone modulation, antioxidant activation, nutrient cycle activation, and systemic resistance induction. The review elucidates key determinants of synthetic community success, including functional complementarity, strain compatibility, and host–environment matching, while revealing a marked quantitative gap between controlled experiments and field performance. Key bottlenecks are identified, including the lack of high-throughput compatibility screening, poorly quantified long-term ecological risks, and the absence of standardized application guidelines across agro-ecological zones. Finally, emerging avenues are discussed, such as microbial–microalgal symbiosis and AI-assisted design, outlining a roadmap for next-generation smart microbial products integrated into climate-resilient farming systems.

Climate change is emerging not only as a threat to global food production but also as a major driver of declining nutritional quality in food crops. Throughout this review, terms such as nutrient decline, imbalance, and nutritional quality changes are used to describe relative changes in the nutritional attributes of edible crop tissues, as reported in the source studies. Elevated atmospheric CO₂, altered rainfall patterns, shifts in solar radiation, and rising temperatures influence soil processes, plant metabolism, and genotype × environment interactions that determine nutrient composition and density. Evidence from controlled experiments, free-air CO₂ enrichment (FACE) studies, field trials, and meta-analyses suggests a recurrent tendency toward reduced concentrations of essential macronutrients and micronutrients, including protein, iron, zinc, and selected B-vitamins in a range of cereals, legumes, and horticultural crops, while responses remain context-dependent and are not universally observed across all nutrients, cultivars, or production systems. These reductions raise serious concerns for populations already experiencing widespread micronutrient deficiencies. This review synthesizes the current knowledge on the extent and mechanisms of climate-driven nutrient decline across major crops, highlighting variability among species, cultivars, and production environments. We also evaluate the potential health consequences, particularly heightened risks of anemia, impaired immunity, developmental challenges, and other deficiency-related disorders. Regions such as South Asia, Southeast Asia, and Sub-Saharan Africa are identified as highly vulnerable due to their strong dependence on nutrient-poor staples and existing burdens of hidden hunger. Furthermore, we assess key mitigation and adaptation pathways, including agronomic innovations, climate-smart agricultural practices, biofortification, advanced breeding strategies, and the emerging use of microbial and cyanobacterial biostimulants to enhance nutritional resilience in cropping systems. Finally, this review provides an integrated synthesis of climate-induced nutrient decline, its health implications for vulnerable populations, and priority actions needed to protect global food and nutrition security in the face of accelerating climate change.

Climate change, soil degradation, and the disruption of global nutrient cycles are placing unprecedented pressure on agricultural systems and global food security. These challenges are increasingly recognized as central concerns for planetary health, as agriculture simultaneously depends upon and alters critical Earth system processes. Microbe-based agricultural inputs (including biofertilizers, biostimulants, and biocontrol agents) have been widely promoted as climate-smart solutions capable of enhancing productivity, resilience, and environmental sustainability. However, despite rapid scientific and commercial advances, their performance in the field remains highly variable and strongly context-dependent. This review critically examines the evidence base underpinning climate-smart microbial solutions, with a particular focus on their capacity to confer climate resilience across diverse crops, soils, and climatic conditions. We synthesize current knowledge on the functional roles of beneficial microorganisms, including extremophilic and stress-adapted taxa, while highlighting key biological, technological, ecological, and socio-economic constraints that limit predictability and scalability. Special attention is given to evidence gaps related to long-term field performance, ecosystem-level impacts, and the trade-offs associated with widespread microbial deployment. We further assess recent innovations such as synthetic microbial consortia, microbiome engineering, advanced formulations, and data-driven decision tools. Then we highlight how these new technologies may address context dependency but still need validation under real-world conditions. Finally, we discuss policy, regulatory, and capacity-building considerations required to responsibly integrate microbial solutions into climate-smart agriculture frameworks. Overall, this review argues that microbial inoculants should be viewed not as universal inputs but as context-specific tools whose successful deployment depends on robust evidence, ecological sensitivity, and system-level integration. Advancing microbial solutions for agriculture will therefore require aligning technological innovation with broader planetary health objectives, ensuring that efforts to enhance agricultural productivity also support long-term ecosystem stability and resilience.

Background/Objectives: Gut microbiota dysregulation has been increasingly implicated in the pathophysiology of autism spectrum disorder (ASD), yet clinical responses to standardized probiotic interventions remain inconsistent, likely reflecting substantial inter-individual variability in baseline microbiome composition, host–microbe interactions, immune tone, and metabolic function. Here, we present a pilot implementation of a metagenomics-guided, personalized synbiotic intervention in children with ASD using the Systematic Microbiome Assessment and Reconstruction Therapy (SMART) framework. Methods: Seven children (aged 5–12 years) underwent longitudinal fecal shotgun metagenomic profiling, and dietary habits, food sensitivities, and regional dietary background were recorded as contextual factors potentially influencing microbiome composition and response to intervention. Individualized synbiotic formulations were constructed based on microbial taxonomic composition and inferred functional capacity and iteratively refined over time. Gastrointestinal outcomes were assessed through caregiver-reported clinical observations, whereas behavioral changes were evaluated using standardized instruments. Results: Several participants demonstrated improvements in gastrointestinal symptoms and selected behavioral domains. Notably, in a subset of participants, improvements in gastrointestinal function preceded measurable behavioral changes. Conclusions: Although limited by a small sample size and lack of a control group, these findings provide preliminary evidence supporting the feasibility of implementing a metagenomics-guided personalized synbiotic framework in ASD and generate hypotheses for future investigation. This work presents a preliminary conceptual framework for integrating microbial composition and inferred functional profiling into individualized intervention design and highlights the potential value of microbiome-informed stratification in future studies of treatment response. Larger controlled studies with objective outcome measures are warranted to further evaluate feasibility, reproducibility, and potential clinical utility. Full article

Smallholder irrigation schemes in semi-arid Zimbabwe are vital for food security but increasingly constrained by declining soil fertility, inefficient water use, and climate variability. Closing nutrient loops through manure recycling offers a potential pathway to improve system sustainability. This study evaluated the effects of manure recycling on maize grain yield and water productivity (WP) under supplemental irrigation at Silalatshani, Zimbabwe, using APSIM simulations across historical and mid-century climates. Simulations included manure rates (0–10 t ha⁻¹), nitrogen levels (20–150 kg N ha⁻¹), irrigation regimes, and climate scenarios, with improved irrigation guided by smart water management (SWM) tools. Grain yield was significantly influenced by nitrogen, manure, and irrigation (p < 0.05), with strong climate × nitrogen × manure interactions. Yields declined under increasing climate stress, predominantly under unimproved irrigation. Manure improved yield and water productivity, with greatest benefits at 2.5–5 t ha⁻¹, beyond which responses diminished. Water productivity gains were modest and constrained by water availability. Economic benefits were limited to moderate manure rates with adequate nitrogen. Combining moderate manure application with appropriate nitrogen fertilisation and improved water management, supported by SWM tools, provides a reliable and economically viable pathway for enhancing productivity, profitability, and resilience under climate variability.

The growing demand for sustainable smart packaging arises from the urgent need to preserve food quality and minimize environmental waste. In this study, multifunctional gelatin-based pH-responsive indicator films were fabricated by incorporating anthocyanins extracted from Hibiscus x archeri W Watson (HAE) and zinc oxide nanoparticles (ZnO-NPs). The incorporation of HAE and ZnO-NPs enhanced surface hydrophobicity, as evidenced by an increase in the water contact angle from 99° to 106°. The Fourier transform infrared (FTIR) analysis verified the lack of new chemical bond formation, indicating that the interactions among components were primarily physical in nature. Distinct colour transitions in buffer solutions of differing pH demonstrated the films’ colorimetric behavior. The films exhibited strong antimicrobial activity against Listeria monocytogenes (18.961 mm), Salmonella typhimurium (18.969 mm), and Aeromonas hydrophila (18.237 mm), whereas the neat gelatin film showed no inhibitory zone. The films also demonstrated superior UV-blocking capacity, with an opacity value (1.34 a.u/mm) compared to the control gelatin film (0.79 a.u/mm). Notably, fish fillets wrapped with the films remained fresh for up to 10 days, compared to day 4 for the unwrapped samples. These findings highlight the considerable potential of multifunctional, active and intelligent packaging for food preservation and real-time freshness monitoring. Full article

Climate change continues to threaten global food security. Climate-smart agriculture (CSA) offers a solution to addressing this challenge in urban agriculture (UA). This paper addresses a gap in the empirical literature on decision-making about the adoption of CSA practices by examining the determinants of CSA adoption among small-scale urban crop (SSUC) farmers in eThekwini (ETH) Municipality, South Africa. Grounded in a utility theory framework, the paper draws on 412 respondents (Cochran-estimated) from a multi-stage sample design across four wards, providing reasonable coverage of SSUC farmers in ETH Municipality. While the sample size is statistically representative of SSUC farmers in ETH Municipality, it is a single metropolitan case rather than universal. The results show strong complementarities among these CSA practices, for example, between OM and CD (r ≈ 0.70, p < 0.001) and M and CD (r ≈ 0.61, p < 0.001). The multivariate probit (MVP) model predicts that the socio-economic and institutional factors age, gender, marital and employment status, education, credit access, extension contact, land tenure, and location (distance from home to farm plots) (p < 0.05) were significant determinants of adopting CSA practices by SSUC farmers. The findings contribute to the global literature on the UA–CSA nexus, demonstrating that socio-economic and institutional factors shape the adoption of bundled CSA practices. While the findings underscore the need for integrated, custom, and UA context-specific policy and extension interventions to strengthen urban food system resilience, UA farmers, practitioners, researchers, and policymakers should apply these insights elsewhere with caution.

Rising global demand for safe, high-quality foods has accelerated the development of rapid, sensitive, and cost-effective analytical technologies for detecting harmful substances and quality markers. Electrochemical sensors have emerged as promising tools for food safety monitoring due to their high sensitivity, fast response, portability, and affordability compared with conventional laboratory methods. This review highlights recent advances in nanostructured electrochemical sensors for detecting key food analytes, including antioxidants, mycotoxins, allergens, and flavor compounds in diverse food matrices. It examines advanced nanomaterials such as metal oxides, MXenes, doped carbon nitrides, and noble metal-decorated graphene, which enhance sensor performance through improved surface area, conductivity, and electrocatalytic activity. Integrated with screen-printed or glassy carbon electrodes, these materials achieve ultra-low detection limits, wide linear ranges, and strong selectivity in complex food systems. The review also explores next-generation applications such as NFC-enabled smart packaging for continuous, non-invasive monitoring across the supply chain. Emerging trends in miniaturization, multiplex sensing, and artificial intelligence are discussed, along with key challenges in translating laboratory innovations into practical commercial solutions for global food safety.

Comprehensive utilization of crop straw (CUCS) is a critical pathway toward sustainable agricultural development, synergizing food security and carbon neutrality goals. However, there remains a lack of systematic empirical evidence regarding its macro-level productivity associations and the conditions under which they materialize. Based on China’s provincial panel data from 2011 to 2023, this paper takes the CUCS pilot policy launched in 2016 as a quasi-natural experiment and employs the difference-in-differences (DID) model to examine the association between CUCS and grain yield, along with its moderating factors and environmental co-benefits. This study yields four main findings. First, CUCS is associated with higher grain yield in pilot regions, and this finding remains robust after a series of endogeneity and robustness checks. Second, the positive association between CUCS and grain output appears to be moderated by fiscal support and innovation–entrepreneurship. The relationship is more pronounced in regions with higher fiscal expenditures on agriculture and environmental protection, as well as more agricultural patents and agricultural enterprises. Third, heterogeneity analysis suggests that the CUCS–grain output association tends to be stronger in regions with richer groundwater resources and more agricultural meteorological observation stations. Fourth, extended analysis indicates that CUCS is also associated with lower particulate matter and agricultural carbon emissions, a pattern consistent with synergistic environmental benefits. By integrating economic and environmental dimensions into a unified analytical framework, this study provides empirical evidence on the contribution of comprehensive straw utilization to grain output and highlights the enabling role of fiscal and innovation environments. These findings offer integrated evidence from China for the policy evaluation of climate-smart agriculture and contribute to the broader sustainable development agenda. Full article

Research on edible and biodegradable film packaging (EBFP) has increased significantly to explore sustainable alternatives to synthetic packaging and mitigate its environmental impacts. Biomaterials extracted from agricultural food waste (AFW) may be utilized for the fabrication of EBFP as an alternative packaging for meat and meat products. The focal point of this review is to explore the potential AFW biomaterials and bioactive compounds available in industry, and their utilization techniques for fabricating EBFP with ideal mechanical parameters suitable for use as a packaging material. Moreover, research studies have been summarized related to EBFP’s efficacy on meat shelf life, physicochemical, oxidative, and microbial qualities during storage experiments. EBFP fabricated with AFW biomaterials, such as proteins, carbohydrates, essential oils, and bioactive compounds, exhibits favorable film-forming capacity, mechanical properties, barrier properties, biodegradability, and synergy with meat. Latest advances in the application of AFW biomaterials and bioactive compounds based on EBFP for meat packaging are directed toward novel fabrication processes such as electrospinning, solvent casting, and combination of both to produce a hybrid film, which markedly improves the mechanical and barrier properties. Moreover, including bioactive materials from AFW enhances the antioxidant and antimicrobial properties of EBFP to combat the oxidative rancidity and bacteria, fungi, and molds in meat to prolong shelf life. Incorporation of AFW biomaterials and bioactive compounds has improved the intelligent properties of EBFP, which has been effectively used in meat packaging to detect freshness and spoilage of meat through color and pH changes.

Mycogenic nanomaterials, nanoparticles (NPs) biosynthesized through fungal enzymatic and metabolic activity, have emerged as a compelling alternative to chemically synthesized nanomaterials, offering fundamental biocompatibility, green production conditions, and biologically functional surface coatings. Fungi, acting as natural “nanofactories,” harness reductases, oxidoreductases, secreted proteins, and secondary metabolites to reduce metal ions into stable NPs under ambient conditions, simultaneously capping the particles with biomolecules that enhance colloidal stability, biocompatibility, and secondary biological activity. Unlike previous reviews that have addressed either biosynthesis mechanisms or applications in isolation, this review uniquely adopts a structured “Promise vs. Barrier” framework across six interconnected thematic pillars, offering the first comprehensive critical synthesis that simultaneously maps mechanistic frontiers, biodiversity gaps, and translational barriers within mycogenic nanotechnology. The present review critically examines both the extraordinary promise and the persistent barriers facing mycogenic nanotechnology across biosynthetic mechanisms, fungal biodiversity, nanomaterial portfolio expansion, biomedical applications, environmental and agricultural utility, and industrial scalability. We highlight how emerging multiomics approaches, integrating transcriptomics, proteomics, and metabolomics, are beginning to decode the molecular blueprints of fungal NP synthesis, while acknowledging that mechanistic knowledge gaps, limited genetic toolkits for non-model fungi, and the absence of standardized protocols continue to impede progress. The fungal kingdom represents a vast, underexplored reservoir of nanofactory potential, with fewer than 1% of known species evaluated to date; strategic bioprospecting using genome mining and machine learning is beginning to unlock this diversity. Mycogenic NPs demonstrate broad-spectrum antimicrobial activity against multidrug-resistant pathogens, selective anticancer activity, biosensing capacity, and applications in wound healing, sustainable agriculture, environmental remediation, and smart food packaging. However, critical deficits persist in clinical validation, long-term toxicity data, manufacturing reproducibility, and regulatory clarity. The review concludes with a tiered roadmap, spanning immediate mechanistic priorities through to long-term synthetic biology and AI-integrated commercialization, and calls for coordinated international action on standardization, reference material development, and harmonized regulatory frameworks to bridge the gap between laboratory promise and real-world application.

Background: Agroecology is increasingly discussed as a strategic response to the combined challenges of drought, ecological degradation, and rural vulnerability. In Morocco, this debate has become particularly urgent because agriculture now operates under persistent hydro-climatic stress, declining water availability, and strong territorial disparities between rainfed, irrigated, mountain, and oasis systems. Methods: This article is based on a structured critical review combined with an interpretive bibliometric synthesis of Moroccan and North African literature on agroecology, water stress, agricultural transition, and food-system resilience. The review was organized through conceptual framing, targeted source selection, thematic screening, and integrative synthesis. Results: Morocco is not an agroecological blank slate. Practices compatible with agroecological transition already exist across the country, including crop diversification, legume rotations, crop–livestock integration, biological regulation, organic amendments, and multifunctional production systems. However, previous reviews have mainly documented practices, projects, or sustainability initiatives without fully explaining why these remain weakly connected, poorly scaled, and insufficiently institutionalized under Moroccan conditions. This review shows that the principal barrier is not the absence of relevant practices but the absence of a coherent transition architecture capable of aligning water governance, farm economics, advisory systems, public incentives, territorial differentiation, and market valorization. The Moroccan case reveals a central paradox: agroecology is most necessary precisely where the structural conditions for its adoption are most fragile. To capture this contradiction, the paper proposes the concept of a Hydro-Agroecological Transition Trap, defined as a condition in which worsening water stress simultaneously intensifies the need for agroecological redesign and reduces the ability of farms and institutions to implement it. Conclusions: The manuscript concludes by proposing a six-pillar transition framework for Morocco based on water-smart agroecology, territorially differentiated pathways, participatory innovation, transition finance and risk-sharing, market construction, and multidimensional assessment. The originality of the study lies in shifting the analysis from a shortage of practices to a shortage of transition architecture, thereby contributing to international debates on agroecological scaling under chronic hydro-climatic stress.
