Biofloc technology (BFT), traditionally centered on feed supplementation and water purification in aquaculture, harbors untapped multifunctional potential as a sustainable resource management platform. This review systematically explores beyond conventional applications. BFT leverages microbial consortia to drive resource recovery, yielding bioactive compounds with antibacterial/antioxidant properties, microbial proteins for efficient feed production, and algae biomass for nutrient recycling and bioenergy. In environmental remediation, its porous microbial aggregates remove microplastics and heavy metals through integrated physical, chemical, and biological mechanisms, addressing critical aquatic pollution challenges. Agri-aquatic integration systems create symbiotic loops where nutrient-rich aquaculture effluents fertilize plant cultures, while plants act as natural filters to stabilize water quality, reducing freshwater dependence and enhancing resource efficiency. Emerging applications, including pigment extraction for ornamental fish and the anaerobic fermentation of biofloc waste into organic amendments, further demonstrate its alignment with circular economy principles. While technical advancements highlight its capacity to balance productivity and ecological stewardship, challenges in large-scale optimization, long-term system stability, and economic viability necessitate interdisciplinary research. By shifting focus to its underexplored functionalities, this review positions BFT as a transformative technology capable of addressing interconnected global challenges in food security, pollution mitigation, and sustainable resource use, offering a scalable framework for the future of aquaculture and beyond.

Cultured meat (CM) is currently experiencing a surge in popularity, primarily due to its promise to produce animal-based products with a lower environmental impact and a higher level of animal welfare. Although CM production remains limited and lacks pre-market approval (except for Singapore and the USA), recent technological advancements have been notable. A greater number of stakeholders, including biotechnology companies, start-ups, private investors, NGOs and big agrifood companies, are entering the CM value chain. This paper aims to aggregate, synthesize, and analyze existing studies on the CM value chain to highlight the characteristics, methodologies, and topics they address. Our secondary purpose is to analyze elements emerging in terms of global value chain dynamics. To do so, this study applies a conceptual framework based on the interplay of the Entrepreneurial Ecosystem and global value chain frameworks. This systematic literature review identifies 43 studies and shows that the most addressed topics are regulations on pre-market approval and labelling, technological progress, the use of patents, the availability and sources of funding, and actors’ roles in the CM market. The analysis and discussion of these findings highlight key aspects of the CM global value chain and present further areas of research to investigate the governance of the chain. Full article

Current food production systems rely heavily on resource-poor small-scale farmers in the global south. Concomitantly, the agrifood systems are exacerbated by various a/biotic challenges, including low-input agriculture and climate crisis. The recent global food crisis further escalates the production and consumption challenges in the global market. With these challenges, coordinated efforts to address the world’s agrifood systems challenges have never been more urgent than now. This includes the implementation of deeply interconnected activities of food, land, and water systems and relationships among producers and consumers that operate across political boundaries. Nature-positive agriculture represents interventions both at the farm and landscape level that include a systems approach for the management of diverse issues across the land-water-food nexus. In the present article, we focus on the history of traditional farming and how it evolved into today’s nature-positive agriculture, including its limitations and opportunities. The review also explains the most impactful indicators for successful nature-positive agriculture, including sustainable management of soil, crops, seeds, pests, and mixed farming systems, including forages and livestock. Finally, the review explains the dynamics of nature-positive agriculture in the context of small-scale farming systems and how multilateral organizations like the CGIAR are converting this into transformative actions and impact. To address the climate crisis, CGIAR established the paradigm of nature-positive solutions as part of its research and development efforts aimed at transforming food, land, and water systems into more resilient and sustainable pathways.

Following the European Commission’s approval of the CAP Strategic Plan and the 21 Italian region (CSR)-related strategic documents, the financial aspect that characterized the single national CAP plan was made available. Here, we present and analyze the final data on the distribution of public resources for interventions between 2023 and 2027. This marks a pivotal period of strategic information for those who follow the evolution of the rural development policy, providing vital indications of policymakers’ priorities. In Italy, where rural development policy is highly regionalized, it is difficult to acquire an overall view of the strategic choices adopted by the individual regions. The primary objective of this article is to offer a comprehensive and enlightening synopsis of the regional choices in the CSRs. It aims to identify shared strategic paths in rural development, with a specific focus on the financial allocation in each of the three historical macro-objectives of the CAP: the competitiveness of the agri-food sector, the protection of the environment, and the revitalization of rural areas. Cluster analysis classification allows for aggregating the strategies adopted, allowing for comparisons across the Italian regions. The results show three regional groups focused on environmental strategy, structural investment measures, and resource distribution that is more balanced between these two approaches. Identifying the strategic choices made by the regions allows policymakers to predict different development trajectories and the progress of the expenditure indicators over the years. At the moment, it is impossible to verify whether the policy mix defined in the budget allocation is consistent with the strategic statements. Full article

The rice–crayfish co-culture system, a representative of Agri-aqua food systems, has emerged worldwide as an effective strategy for enhancing agricultural land use efficiency and boosting sustainability, particularly in China and Southeast Asia. Despite its widespread adoption in China’s Jianghan Plain, the exact spatiotemporal dynamics and factors influencing this practice in this region are yet to be clarified. Therefore, understanding the spatiotemporal dynamics and influencing factors of the rice–crayfish fields (RCFs) is crucial for promoting the rice–crayfish co-culture system, and optimizing land use policies. In this study, we identified the spatial distribution of RCF using Sentinel-2 images and land use spatiotemporal data to analyze its spatiotemporal dynamics during the period of 2016–2020. Additionally, we used the Multiscale Geographically Weighted Regression model to explore the key factors influencing RCF’s spatiotemporal changes. Our findings reveal that (1). the RCF area in Jianghan Plain expanded from 1216.04 km² to 2429.76 km² between 2016 and 2020, marking a 99.81% increase. (2). RCF in Jianghan Plain evolved toward a more contiguous and clustered spatial pattern, suggesting a clear industrial agglomeration in this area. (3). The expansion of the RCFs was majorly influenced by its landscape and local agricultural conditions. Significantly, the Aggregation and Landscape Shape Indexes positively impacted this expansion, whereas proximity to rural areas and towns had a negative impact. This study provides a solid foundation for promoting the rice–crayfish co-culture system and sustainably developing related industries. To ensure the sustainable development of rice–crayfish co-culture industries in Jianghan Plain, we recommend that local governments optimize the spatial layout of rural settlements, improve transportation infrastructure, and enhance regional agricultural water sources and irrigation system construction, all in line with the national strategy of rural revitalization and village planning. Additionally, promoting the concentration and contiguity of RCF through land consolidation can achieve efficient development of these industries. Full article

Mediterranean agriculture asks for sustainable strategies to prevent actual soil organic matter decline rates. Composting agri-food by-products for application in farmland, besides contributing to a circular economy at regional or local scales, may improve soil resistance to physical degradation. Aggregate stability (AS) is a crucial property for building up such resistance. Olive pomace is an abundant by-product of the olive oil industry that may be valorized through composting. This study aimed to assess the influence on AS of olive-pomace-based composts (OPC) applied to a sandy loam Leptosol and a clay loam Fluvisol. To assess the effects of compost characteristics on AS, three OPCs resulting from different olive pomace proportions in the composting raw material (44, 31, and 25% by volume) were applied to aggregate samples in three doses (10, 20, and 40 t.ha⁻¹, plus control) with fine and coarse grain sizes. Controlled laboratory conditions subjected samples to daily wetting-drying cycles during a 30-day experiment. AS was measured by wet sieving. OPC application significantly increased AS in the Leptosol amended with fine (+15% vs. control) and coarse (+19%) grain-size compost. In well-aggregated Fluvisol, amendment induced a significant increase in AS only in the compost coarse grain size (+12%). The application dose significantly affected AS, with 10 t.ha⁻¹ being the best-performing dose. OPC applications in weakly aggregated soils are seemingly an encouraging soil management practice for improving soil resistance to physical degradation and reducing soil organic matter decline rates in Mediterranean farmland.

In Italy, the wine supply chain is a cornerstone of the national agri-food system and a driving force for the entire economy. The aim of this study is to map the profile of Italian wine companies through the analysis of multiple case studies. The study focuses specifically on companies in the Marche region, investigating their features and supply chain, with a specific focus on product and system certification adopted, marketing policies implemented, and the businesses’ relationship with institutions. A total of 18 companies participated in the study. The primary data for the research was collected through semi-structured interviews lasting 1 h, based on an interview protocol. The results show that the supply chain for the wine sector is configured to be short, even when cooperatives act as an aggregator. The small size and limited financial resources make it particularly difficult to promote the wine outside its reference context, and there is a lack of a network strategy at the local level. Many companies consider organic certification a disadvantage since it tends to homologate production to the large wine industries, making the product’s naturalness, typicality, and craftsmanship disappear.

Apricot (AS), peach (PS), and plum shells (PlS) were examined as sustainable aggregates for non-structural lightweight concrete. The extraction of natural resources has a significant environmental impact and is not in line with the Sustainable Development Goals (SDGs) of Agenda 2030. Recycling agri-food waste, such as fruit shells, fully respects circular economy principles and SDGs. The chemical and physical properties of the shells were investigated using scanning electron microscopy (SEM) for microstructure analysis and TG-MS-EGA for thermal stress behavior. Two binding mixtures were used to prepare the concrete samples, one containing lime only (mixture “a”) and one containing both lime and cement (mixture “b”). Lime is a more sustainable building material but it compromises mechanical strength and durability. The performance of lightweight concrete was determined based on the type of aggregate used. PS had a high-water absorption capacity due to numerous micropores, resulting in lower density (1000–1200 kg/m³), compressive strength (1–4 MPa), and thermal conductivity (0.15–0.20 W/mK) of PS concrete. AS concrete showed the opposite trend (1120–1260 kg/m³; 2.8–7.0 MPa; 0.2–0.4 W/mK) due to AS microporosity-free and denser structure. PlS has intermediate characteristics in terms of porosity, density, and water absorption, resulting in concrete with intermediate characteristics (1050–1240 kg/m³; 1.9–5.2 MPa; 0.15–0.3 W/mK).

The horticulture sector has been directed by European guidelines to improve its practices related to environmental sustainability. Moreover, the practice of horticulture in urban areas is increasing since it provides fresh products that are locally produced. At the same time, horticulture needs to implement circular economy approaches and energy-efficient models. Therefore, to address these issues, this study investigated the effects of an integrated fertilizer-box-based cultivation system equipped with LED lights and coated porous inorganic materials (C-PIMs), which was applied as fertilizer, on Lactuca sativa L. growth. Two different types of lightweight aggregates were formulated considering agri-food and post-consumer waste, and they were enriched with potassium and phosphorus. Involving waste in the process was part of their valorization in the circular economy. Using PIMs as fertilizers enabled the controlled release of nutrients over time. The tests were carried out in controlled conditions using two LED lighting systems capable of changing their light spectrum according to the growth phases of the plants. The effects of two different lighting schemes on the growth of lettuce plants, in combination with different amounts of aggregates, were studied. The results showed that increasing the amount of C-PIMs statistically improved the lettuce growth in terms of dry biomass production (+60% and +34% for two different types of PIM application) when the plants were exposed to the first LED scheme (LED-1). Plant height and leaf areas significantly increased when exposed to the second LED scheme (LED-2), in combination with the presence of C-PIMs in the soil. The analysis of the heavy metal contents in the lettuce leaves and the soil at the end of the test revealed that these elements remained significantly below the legislated thresholds. The experimental achievements of this study identified a new approach to improve the environmental sustainability of horticulture, especially in an urban/domestic context. Full article

Multicriteria decision making (MCDM) is a field that helps decision makers evaluate alternatives based on multiple criteria and encompasses scoring, distance-based, pairwise comparison, and outranking methods. Recent developments have aimed to solve specific problems and overcoming the limitations of previous methods. This paper proposes a new axial-distance-based aggregated measurement (ADAM) method, which is used in combination with the best-worst method (BWM) to evaluate agri-food circular economy (CE)-based business models (BMs) to create a more sustainable and efficient system for producing and consuming food. This paper proposes nine BMs, which were evaluated against eight criteria. The BWM method was used to obtain the criteria weights, while the ADAM method was used to obtain a final ranking of the BMs. The results indicate that a sustainable circular agri-food supply chain is a BM that can bring companies the most significant progress in business and strengthen their position in the market. We concluded that the ADAM method is effective for solving MCDM problems and that, overall, the model is an effective tool for solving the problem defined in this study. The main contributions are the development of a new MCDM method and a hybrid model, the establishment of the framework for evaluation and selection of CE-based BMs, and the identification of the most important ones.

The global literature widely uses Revealed Comparative Advantage (RCA), Lafay Index (LFI), Export Diversification (EDI), Hirschman (HI), and Major Export Category (MEC) to analyze international trade flows, though agricultural trade, specifically agri-food commodities consisting of food and feed commodities, is neglected in empirical works. Furthermore, the determinants of Revealed Comparative Advantages and the Lafay Index have received little attention, with little focus on the relationships between food insecurity as measured by the Household Food Insecurity Access Scale (HFIAS) and the aforementioned factors, including the RCA and LFI indices as explanatory variables with other macroeconomic variables. The purpose of this study was to ascertain the competitiveness of Namibia’s agri-food products, the factors that influence it, and their implication for food security. This study attempts to answer which factors affect agri-food comparative advantage, which agri-food commodities have a comparative advantage and disadvantage, and what the implications are to food security. The study employed regression analysis, the Household Food Insecurity Access Scale, and various indices. Revealed Comparative Advantage and Lafay Index indicated a mixed result during the study period. Export Diversification and Hirschman indices indicated a less concentrated trade structure throughout the study period. The results of the market structure of the international agri-food market estimated by the Major Export Category revealed that Namibia was unduly dependent on agri-food commodities incorporated in this study. The regression result showed a significant negative influence of labor and land productivity on the aggregated RCA and LFI for agri-food commodities. Land productivity and GDP per capita impact the degree of food insecurity in Namibia. The study concludes that Namibia was not dependent on international trade of agri-food commodities and had little bearing on food security. These analyses enlighten policymakers about the competitiveness of the agri-food business and its implications for food security through evidence-based policy development. Full article

Neurodegenerative diseases, characterized by progressive loss in selected areas of the nervous system, are becoming increasingly prevalent worldwide due to an aging population. Despite their diverse clinical manifestations, neurodegenerative diseases are multifactorial disorders with standard features and mechanisms such as abnormal protein aggregation, mitochondrial dysfunction, oxidative stress and inflammation. As there are no effective treatments to counteract neurodegenerative diseases, increasing interest has been directed to the potential neuroprotective activities of plant-derived compounds found abundantly in food and in agrifood by-products. Food waste has an extremely negative impact on the environment, and recycling is needed to promote their disposal and overcome this problem. Many studies have been carried out to develop green and effective strategies to extract bioactive compounds from food by-products, such as peel, leaves, seeds, bran, kernel, pomace, and oil cake, and to investigate their biological activity. In this review, we focused on the potential neuroprotective activity of agrifood wastes obtained by common products widely produced and consumed in Italy, such as grapes, coffee, tomatoes, olives, chestnuts, onions, apples, and pomegranates.

Due to the environmental radicalization of European politics, which is reflected in the European Green Deal, Farm to Fork strategy, and new CAP 2023–2027, this paper aims to determine the impact of agri-environmental indicators on soil productivity based on the land productivity function model. The paper focuses on the Western Balkans countries, which are in the process of European integration and which, in the coming period, need to harmonize their agricultural policy with the CAP. First, the aggregate Cobb–Douglas production function has been used to create a land productivity function. Then, the sources of land productivity growth have been calculated, which can be particularly interesting in the context of agri-environmental indicators, such as fertilizer use and livestock density. The research results showed that land productivity is the most elastic concerning changes in the number of livestock units per hectare. Consequently, reducing livestock units had a markedly negative effect on productivity. In addition, the research results showed that using mineral fertilizers is a crucial source of growth in land productivity in these countries. These results imply that the creators of the agricultural policy must carefully assess the pace at which they will harmonize ecological and economic goals, especially if they take into account the current Ukraine crisis that can disrupt the food market.

Assessing the sustainability of agri-food chains is challenging for several reasons. It should account for the impacts on environmental, social, and economic wellbeing simultaneously, considering both the individual links in the chain and the chain as a whole. The primary aim of this study is to assess the conditions for meeting the sustainability criteria of a legume-based agri-food chain in Slovenia. Therefore, a quantitative sustainability assessment methodology was developed, using a multi-stakeholder approach, which upgraded the traditional SWOT (strengths, weaknesses, opportunities, and threats) analysis. Our approach, called ‘Multi-SWOT’, aggregates the SWOT table inputs identified by stakeholders into factors, themes and focus areas, according to their importance for the agri-food chain, for each sustainability pillar, and links in the chain. By accounting for the relative number of incentives (beneficial factors) and barriers (constraint factors) we identified those factors that enhance the sustainability of the Slovenian legume-based agri-food chain and the factors jeopardising it. The incorporation of multi-stakeholder perspectives presents an innovative approach that adds value to a standard SWOT analysis. The study serves as a guide to help decision-makers better understand the multidimensionality of sustainability and identify effective activities to support and strengthen the current legume agri-food chain in Slovenia.

The paper, based on RCA, LFI and GL indices, and logistic regression analysis, allowed us to track the dynamics of the comparative advantage/disadvantage of the Czech Republic in individual commodity aggregates in relation to individual EU partners, and to comprehend the role of the main production factors. The only production factor with a statistically significant effect is capital. Trade with countries richly endowed with agricultural land and capital, in most cases, appeared not favorable for the Czech Republic in terms of having a comparative advantage over them, if measured with LFI index. The values of the GL index disclosed that trade with these countries is mostly of an inter-industry character. The analysis revealed the following top-3 mostly competitive Czech aggregates: S3-08 (animal feed stuff), S3-06 (sugar and sugar preparations), along with S3-04 (cereals and cereal preparations). Some aggregates appeared to not have any comparative advantage: S3-01 (meat, meat preparations), S3-05 (vegetables and fruits), and S3-41 (animal oils and fats). Speaking of developmental trends, from 2000 to 2019 the Czech Republic has managed to improve its position in agri-food trade within the EU-27 by 43.81% if measured with LFI, and by 51.63% if measured with RCA. These positive changes also appeared to be statistically significant. Full article
