| Abstract: | Climate change and violent conflict are defining challenges of our time. However, it is not yet understood how they interact in shaping human welfare and food security, how their interaction shapes gendered outcomes, or how social protection systems can mitigate their impact. To address these knowledge gaps, we first examine how household food insecurity relates to conflict and climate shocks and whether these associations are gender-sensitive. Second, we test what mechanisms can reduce the negative impacts of these shocks. Our empirical analysis relies on novel survey data of 7, 908 rural households collected across 14 states in Sudan in 2022. Sudan currently faces floods, droughts, and violent conflict affecting agricultural production and food supply. We find that climate shocks do not significantly affect food consumption scores (FCS), while exposure to violent conflict leads to a substantial decrease in FCS. Both productive and non-productive assets increase FCS for all households, especially female-headed households. Longer distances to agricultural input and output markets correlate with lower FCS, particularly for male-headed households. Women’s social group membership positively impacts on FCS for female-headed households. However, women do not receive additional benefits from other social networks during climate and conflict exposure, while male-headed households benefit from all types of social networks. Income diversification is identified as a key strategy for improving FCS, particularly for female-headed households during conflict. Informal cash transfers significantly improve FCS, especially for female-headed households. In contrast, formal cash transfers negatively correlate with FCS, although they positively impact on male-headed households during violent conflict. Overall, we recommend targeted social protection programmes that address gender disparities and enhance resilience among vulnerable populations. |

| Abstract: | This report is the 2023 edition of the annual U.S. Agricultural Policy Review series documenting developments in U.S. Federal policies related to production agriculture, agrofood value chains, and food and nutrition assistance. Most prominently, 2023 saw the expiration of many provisions of the Agriculture Improvement Act of 2018 (AIA; Public Law 115–334) at the end of fiscal year 2023, which were then extended through the end of fiscal year 2024 as part of the Further Continuing Appropriations and Other Extensions Act, 2024 (Public Law 118–22). Developments specifically in the production agriculture domain were focused on disaster assistance, continuing to address supply chain challenges that emerged during the Coronavirus (COVID-19) pandemic, improving and streamlining program delivery, and agricultural climate mitigation. Developments related to agrofood value chains have focused on increasing competition and transparency, enhancing resilience, and improving sustainability. Major changes in USDA food and nutrition assistance programs largely have related to the expiration of waivers and policies implemented in response to the Coronavirus (COVID-19) pandemic, which expanded the scope and reach of the programs and allowed for flexibilities in their administration. |

| Abstract: | Climate change poses significant challenges for countries in Northern Africa such as Morocco. Smallholder farmers are especially vulnerable to climate change because they experience several challenges in the adoption of climate-resilient practices. The sustainable and well-managed cultivation of the cactus pear (Opuntia ficus-indica) could contribute to conservation agriculture (CA) in dry climates threatened by climate change. Due to its high-water-use efficiency and ability to withstand extremely dry conditions, the cactus pear is increasingly being recognised as a more sustainable alternative to traditional livestock foraging in dryland areas. Compared to many other common crops and fodder, the cactus pear is easy to establish, maintain, and has a wealth of uses. Two innovative cultivation techniques are being developed: (1) the use of mixed inoculum formulations containing AMF (Arbuscular Mycorrhizal Fungi) and PGPB (Plant Growth-Promoting Bacteria) in the soil; and (2) intercropping between perennial (cactus pear) and short-term species (field crops). We propose to identify factors that could facilitate farmers' innovation adoption. We conducted face-to-face interviews with 24 smallholder cactus pear farmers in Morocco. We concluded that farmers do not yet have a comprehensive understanding of the principles of the innovations. The main aim of farmers was to increase production and income. Farmers, in general, pay little attention to the environment. The recommendations that are given in relation to these issues are that training and social networks are essential in innovation transfer, adoption needs to be facilitated by providing resources, an innovation transfer needs to be adapted to the current and future needs of farmers, and we need patience so that farmers can slowly learn the innovations. |

| Abstract: | Climate change will increase average temperatures and the frequency and intensity of summertime droughts; those shifts will in turn affect forage production in grassland-based livestock farms. Farmers will accordingly likely have to implement adaptation strategies to cope with the effects of climate change. We hypothesized that farmers' resilience strategies would depend on (i) their intention to adapt to climate change, which partly results from previous climate risk exposure, (ii) how they perceive the values and disvalues of multi-species permanent grasslands (PGs), and (iii) that both of the aforementioned factors would vary according to the geographical context of each farm. We carried out 15 semi-structured interviews with dairy cattle farmers in the French Massif Central; the farms were distributed along a range of climatic and topographic conditions. We used (i) the Model of Proactive Private Adaptation to Climate Change to analyze farmers' individual process of adaptation, (ii) the Integrated Nature Futures Framework to analyze farmers' perception of multi-species PGs, and (iii) text analysis to identify the farmers' adaptation strategies. Nine of the farmers felt that they were already adapted to climate change or that they had a plan in place to implement new adaptations in the future. We observed straightforward relationships between these farmers' perception of PGs and their choice of adaptation strategy; those relationships varied, however, with the geographical context of each farm. Farmers in the northern Massif Central and southern uplands highlighted the values of PGs and considered PGs to be central to their adaption strategies. Conversely, farmers in the southern lowlands mostly referred to the disvalues of PGs; they based their adaptation strategies on temporary grasslands and forage crops. Three of the farmers believed that climate change posed a significant risk, but they foresaw little room to maneuver. Despite acknowledging the values of PGs, those individuals did not intend to use PGs to adapt to climate change. The final three farmers did not intend to adapt to climate change; their reasoning stemmed from either a mindset of fatalism or their acknowledged desire to retire soon. Extreme events such as the summertime drought of 2003 and human factors such as intergenerational transmission of farm can accordingly facilitate or inhibit climate change-related adaptation. It is accordingly important to take into account both socio-psychological and environmental factors when analyzing how grassland-based farmers transition to more climate change-resilient systems. |

| Abstract: | It is estimated that 37 % of all food produced in Mexico for human consumption is lost or wasted, while the national dairy herd consumes approximately 455, 000 tons of feed annually. This study proposes a method to carry out a national inventory of food losses (FL) from the agro-industry that can replace conventional feed in livestock diets. FL chosen should meet criteria such as documented evidence of its use as livestock feeds, knowledge of existing treatments to transform them into by-product feeds, information on its availability, nutritional composition data, and proximity to dairy farms. The method was applied in Mexico, considering national agricultural statistics data and livestock production statistics at the municipal level. FL estimation was made using the Commission for Environmental Cooperation method, considering the pre-harvest, post-harvest, and processing stages of the agri-food supply chain. The interaction between milk production and FL generation was calculated using the global desirability function and spatially assessed using geographic information systems. Twenty-nine potential "strategic food loss" were identified, including maize, carrots, broccoli, cotton, and potato. The highest opportunities to use FL as by-product feeds are in 52 municipalities, mainly in the West Central region, where the Bajio dairy area is located. This research is the first step toward developing a market for by-product feeds in a circular economy scheme that reduces the environmental impacts and costs in the dairy industry. |

| Abstract: | This study investigates the Public Agricultural Expenditure Efficiency (PAEE) in Sub-Saharan African (SSA) countries, focusing on the impact of the proportion of cash crops production on this efficiency. We first compute the Bias-corrected Technical Efficiency (BTE) Scores of 39 SSA countries from 2003 to 2017, using the Bootstrap Data Envelopment Analysis method, with per capita public agricultural expenditure as input, and food security indicators as output. Second, we assess the effect of cash crops share in harvested land (CSHL) on the PAEE using Beta regression. (i) our results show that in most SSA countries(79%), CSHL is on average less than 15%. (ii) findings indicate a significant positive effect of CSHL on the PAEE, suggesting that a higher proportion of cash crops in agricultural production enhances food security. (iii) results for SSA countries where CSHL is high are in line with the aim of the commitments made by African countries in Maputo (2003) declarations to fight hunger by allocating at least 10% of their public spending to agriculture—aligning with the Sustainable Development Goal of Zero Hunger by 2030. Our results are robust to a battery of robustness tests. |

| Abstract: | To accelerate the transition towards inclusive, ecological, just and economically viable food systems, insights into appropriate governance models and principles are needed. This article aims to understand how food system governance is linked to and can contribute to sustainability. A review of 34 articles addressed food system governance, sustainability, current barriers and potential solutions. Some authors propose new, participatory, collaborative and democratic governance models to achieve a sustainable food system transition. Other authors consider a lack of integrated policies across sectors and siloed governance major barriers to holistic sustainability agendas and food system approaches. Three main elements of governance emerged from the reviewed literature: (i) interactions between actors, (ii) control and power balances, and (iii) (in)formal rules. Our analysis provides a fourth element: the orchestration of (multiple) food systems and policies. These four elements are integrated into a novel conceptual framework for consistently researching food systems governance for sustainability. The latter is now defined as ‘the continuous process of orchestration of policies and (multiple) food systems consisting of diverse interacting actors, respecting (in)formal rules and striving to provide food for all, in equitable and environmentally-friendly ways, at any time and in any context'. |

| Abstract: | Greece features a diverse landscape with significant land cover changes over recent decades, impacting sustainability components such as biodiversity, climate stability, and ecosystem services. Monitoring and mapping these changes are essential for informed land management. This research utilizes freely available satellite data (Remote Sensing) and open-source tools (QGIS and Excel sheets) to assess key metrics, including land cover change, productivity, and soil carbon storage. We also link these metrics to estimate the Sustainable Development Goal (SDG) 15, and the indicator SDG15.3.1, considering the sustainable land use changes. The spatial synthesis of these metrics reveals areas of land improvement, stability, and degradation from 2010 to 2020, offering insights into Greece's land dynamics historically. Results highlight that most of the land remains in a stable state of "land sustainability, " but certain regions require targeted interventions to address degradation. Notably, urban expansion and intensive agriculture drive localized declines in ecosystem quality, while forest management and conservation policies contribute to stability and improvement. The methodology emphasizes transparency and replicability, with publicly available code and results tailored for Greece's unique environmental and socio-economic context. By aligning national efforts with SDG targets, this work supports policies for balancing economic growth with ecological resilience, ensuring the sustainable use of terrestrial ecosystems, and enhancing the quality of life for present and future generations in Greece. |

| Abstract: | How do cash crop price shocks shape migration intentions in rural, agriculturally intensive regions of sub- Saharan Africa? Focusing on communities heavily reliant on cash crop income, we examine migration intentions following negative cash crop price shocks. Using a difference-in-differences approach with continuous treatment, we analyze data from 278, 898 rural individuals across 432 regions in 41 sub- Saharan African countries. The results indicate that a negative cash crop price shock increases the likelihood of international migration intentions, an effect that is particularly pronounced in regions with higher cropland intensity. These findings are confirmed by several additional analyses and contribute to a better understanding of the relationship between agricultural livelihood instability and migration intentions in sub-Saharan Africa. |

| Abstract: | Agricultural systems are becoming increasingly complex, requiring data-driven, science-supported models to address their multifaceted challenges and ensure sustainable management. In Greece, agriculture is a critical sector, contributing significantly to the economy and rural livelihoods, but it faces pressing challenges such as competing water uses, energy demands, lackluster productivity, and environmental pressures. This study presents a comprehensive multi-model assessment of Greece's Water-Energy-Food-Ecosystems Nexus, evaluating agricultural production alongside its energy and water requirements and quantifying the associated air pollution impacts at the national level. For the first time to our knowledge, we connect the FABLE Calculator (the software of the FABLE Consortium), with LEAP (Low Emissions Analysis Platform, from the Stockholm Environmental Institute), and the WaterReqGCH (a model developed by the Global Climate Hub). The FABLE Calculator provides detailed estimates of the agricultural and livestock production, which are then used by LEAP to calculate the respective energy demand and the associated greenhouse gases emissions, per fuel type used. The WaterReqGCH model uses the activity levels used in FABLE and LEAP in order to estimate the water requirements of the agricultural and livestock sector. The models run under a combination of mild-medium-extreme future scenarios until 2050 considering the Representative Concentration Pathways (RCPs) and the Shared Socioeconomic Pathways (SSPs) scenarios. The combination of the insights provided by this multi-model approach are useful and holistic evidence for policymaking. |

| Abstract: | Excerpt from the report Introduction: This report assesses the current state of carbon markets and provides foundational information to determine the establishment of a Greenhouse Gas Technical Assistance Provider and Third Party Verifier Program at the U.S. Department of Agriculture (USDA). It begins with an overview of current carbon credit markets and activities related to forestry and agricultural carbon credit generation. It then provides information on the supply and demand for carbon credits; descriptions of protocols and registries and other systems used to generate carbon credits; a summary of quantification and accounting methods; an assessment of barriers to entry into carbon markets; and options to address these barriers. Finally, the report discusses opportunities for other voluntary markets outside of voluntary environmental credit markets to foster the trading, buying, or selling of credits that are derived from activities that provide other ecosystem service benefits, including activities that improve water quality, water quantity, wildlife habitat enhancement, and other ecosystem services. |

| Abstract: | We study the consequences of a clash between contemporary development initiatives and traditional economic practices in Africa. Crop agriculture has expanded considerably across the continent in recent years. Much of this expansion has occurred in traditionally pastoral areas, where land is typically managed according to customary arrangements. This is believed to be a major cause of conflict between pastoral and agricultural ethnic groups. We test this hypothesis using geocoded data on agricultural development projects across Africa from 1995-2014. We find that implementing agricultural projects in traditionally pastoral areas leads to an almost two-fold increase in the risk of conflict. We find no equivalent effect for agricultural projects implemented in traditionally agricultural areas, nor for non-agricultural projects implemented in either location. We also find that this mechanism contributes to the spread of extremist-religious conflict in the form of jihadist attacks. The effects are muted when agricultural projects are paired with pastoral projects. This is more likely to occur when pastoral groups have more political power. Despite these effects on conflict, we find that crop agriculture projects increase nighttime luminosity in both agricultural and pastoral areas. Evidence from survey data suggests that the gains in pastoral areas are concentrated in non-pastoral households. Our findings indicate that "development mismatch"---i.e., imposing projects that are misaligned with local populations---can be costly. |

| Abstract: | Genetically modified (GM) crops have been adopted by some of the world's leading agricultural nations, but the full extent of their environmental impact remains largely unknown. Although concerns regarding the direct environmental effects of GM crops have declined, GM crops have led to indirect changes in agricultural practices, including pesticide use, agricultural expansion, and cropping patterns, with profound environmental implications. Recent studies paint a nuanced picture of these environmental impacts, with mixed effects of GM crop adoption on biodiversity, deforestation, and human health that vary with the GM trait and geographic scale. New GM or gene-edited crops with different traits would likely have different environmental and human health impacts. |

| Abstract: | Climate change, compounding with non-climatic stressors, impacts socio-ecological systems and threatens the human habitability of places. Moreover, the complex interplay of drivers and impacts introduces high levels of uncertainty, complicating future predictions of habitability. While habitability is internationally recognised as an important condition in adaptation studies, its definition and conceptualisation are still under discussion. Moreover, traditional studies dealing with habitability mostly apply a top-down approach and focus on its material aspects, such as housing, food, and water, while overlooking local knowledge, and needs of the affected communities, who better know what makes their place acceptable to live in. Risk Storylines (RS) are a promising tool that can apply a bottom-up approach and co-create a shared definition of habitability while managing uncertainty within the context of multiple climatic risks. The Habi(Li)ter project aims to adopt the RS as an exploratory tool to investigate present and future habitability in Lorraine (France) under climate change and multi-risk interactions and define suitable modelling strategies to assess it in a quali-quantitative way. In particular, the RS will be applied to: 1. Understand how climate hazards and local vulnerabilities interact, leading to cascading impacts across multiple sectors. The narrative nature of this tool will facilitate stakeholders in describing the temporal dynamics of interest, specifically regarding the development of hazards and their impacts over time (particularly for long-onset hazards and chronic stresses), as well as socio-economic development pathways that might affect future habitability. Moreover, the narrative description of the risk dynamics provided by the RS can guide the implementation of conceptual models tailored to capture the most influential conditions, such as temporal dynamics (System Dynamics) or risk-informed approaches (Impact Chains). 2. Identify local habitability factors. RS are useful for exploring the uncertainties that most influence local habitability and determining which adaptation strategies should be investigated. 3. Develop Scenarios for Investigation. RS is an "exploratory" tool, to manage uncertainty by identifying a subset of futures that are "plausible" for stakeholders. Silvia De Angeli is the principal investigator of the Habi(Li)ter project, funded by Lorraine Université d'Excellence and supported by Eurac Research. Starting in October 2024, the project will benefit from a research exchange with Stefano Terzi, co-author of this contribution. The INQUIMUS workshop will offer valuable insights into the potential of RS for bottom-up climate risk and habitability assessments, enhancing our understanding of how to address these complex challenges effectively. |

| Abstract: | Food standards, which are used to signal adherence to sustainability goals or a specific origin, have deep political implications. Standards crafted by retailers, processors, or third-party actors such as non-governmental organizations (NGOs) often disempower farmers. Moreover, due to the liberalization and globalization of many food value chains, producer organizations (POs) lost some of their legal privileges and market protections. This paper analyzes how POs in the Global North sought to regain their control over food markets by establishing their own standards. These strategies and their consequences are considered across three dimensions: the internal life of the PO, the relevant market institutions, and the relationship between the PO and the state. Our case studies ( N = 5) performed in France and in Québec, a French-speaking province of Canada, span across a variety of food sectors. Drawing on qualitative material, we designed our explanatory framework through an abductive, iterative method. Although standards crafted by POs have, in some cases, reshaped market institutions to their advantage and have repositioned them in the governance of food markets, they come at a cost. They may create tensions within POs and clash with the agrarian values of solidarity, democracy, and autonomy. Overall, this article challenges the assumption that food standards are mainly governed by private actors and sheds light on the new alliances and new identities of POs. |

| Abstract: | Digital finance in agriculture is a nascent technology which could help improve rural financial inclusion. In an experimental evaluation of a digital lending product for farmers in Southern Ghana, credit increases farm investments but has few statistically significant average effects on downstream outcomes. However, logistical challenges generated imperfect compliance with the treatment assignment, with some loans delivered in a timely fashion for agricultural investments and others coming later. We cautiously exploit this unplanned non-experimental implementation heterogeneity and conclude that agriculturally-focused digital credit platforms have potential to tackle persistent rural financial market imperfections, but the timing seems critical and deserves further study. |

| Abstract: | The global food system provides the energy that supports human metabolism, with complex spatial interdependencies between food production, transformation, and consumption. Empirical food system data for these global processes are often fragmented and inconsistent, with only certain components captured in spatially resolved formats. Here we propose a flexible approach to allocating country-level food system data subnationally. We estimate the spatial patterns of food energy production and supply, which we compare to estimates of human metabolism based on average body size. We downscale these rates onto a one-degree resolution grid with 95 corresponding food types to derive an internally consistent, energy-conserving, and spatially resolved dataset. We show that national food supply varies linearly with metabolism per capita, with about half the variation in food supply explained by metabolic rates. Our data processing pipeline is openly available and can readily incorporate new inputs in order to advance trans-disciplinary food system modeling efforts. |

| Abstract: | In a world rapidly transitioning, food consumption away from home is rising, therefore representing an increasing share of individual's diet. Food consumed away from home negatively impacts diet, nutritional status and consequently has detrimental effects on health. In some contexts, where individual level dietary intake surveys are not regularly conducted, this behavior is not well documented leading to a gap of knowledge. The aim of the present study was to develop and validate in Burkina Faso and Vietnam specific modules that could be added to Household Consumption and Expenditure Surveys that are usually regularly conducted worldwide, in order to document the economic and nutritional importance of food consumption away from home. In each country, two survey modules, one long (100 food items) and one short (30 food items) were developed, to measure individual-level food consumption away from home over the last 7 days. The modules were relatively validated in comparison with data from three non-consecutive 24-hour dietary recalls conducted over the same 7-days period. The validation was conducted in different settings (urban, peri-urban and rural) in Burkina Faso (n = 924) and Vietnam (n = 918). In both countries, a good concordance between the 24-hour dietary recalls and the modules in their ability to identify a person as having consumed food away from home (>77%) was found. However, in both countries, both modules underestimate the mean energy intake coming from foods consumed away from home (from 122 to 408 kcal) while they overestimate the budget allocated to it (from -0.07 to -0.29 USD/day). None of developed food away from home modules were considered as valid. There is a need for the international community to continue to work on developing and validating tools capable to estimate nutritional intakes related to food consumption away from home and that could be added to regular national household-level surveys. |

| Abstract: | Using data from the Farm Accountancy Data Network (FADN) for the period 2010 to 2022, this article presents an analysis of French farm income trends and their dispersion. The indicator used for this study is the family farm income per non-salaried agricultural work unit. First, the analysis is carried out for all production types combined. It highlights a high degree of inter-annual variability on the average income of French farmers, with a peak of €55, 800 in 2022 and a low point of €21, 300 in 2016 (for an average of €34, 100 per year over the 2010-2022 period). A typological grid distinguishing 64 boxes is then proposed to demonstrate the influence of three key indicators on the level of income, namely "labor productivity", "productive efficiency" and "the farm's ability to meet its financial commitments". Secondly, the analysis is carried out according to production types. While taking into account the differences within each one, this work shows that the average income generated by farms specializing in ruminant production is, in a long-term approach, clearly lower than that obtained in other speculations such as field crops, viticulture or pork production. Finally, by combining the three indicators mentioned above, a method can be used to divide dairy and beef farms into eight "economic performance" classes. |
| Abstract: | En utilisant les données du Réseau d'information comptable agricole (RICA) sur la période 2010 à 2022, cet article présente une analyse de l'évolution des revenus des exploitations agricoles françaises et de leur dispersion. L'indicateur utilisé pour en rendre compte est le résultat courant avant impôt (RCAI) par unité de travail agricole (UTA) non salariée. Dans un premier temps, l'analyse est conduite toutes orientations de production confondues. Elle met en évidence une forte variabilité interannuelle du revenu moyen des agriculteurs français, avec un pic à 55 800 euros en 2022 et un creux à 21 300 euros en 2016 (pour une moyenne de 34 100 euros par an sur la période 2010-2022). Une grille typologique distinguant 64 cases est ensuite proposée pour démontrer l'influence de trois indicateurs essentiels sur le niveau des revenus, à savoir « la productivité du travail », « l'efficience productive » et « la capacité de l'exploitation à faire face à ses engagements financiers ». Dans un deuxième temps, l'analyse est menée selon les orientations de production. Tout en rendant compte des écarts internes à chacune d'elles, ce travail démontre que le revenu moyen dégagé dans les exploitations spécialisées en productions de ruminants est, dans une approche de long terme, clairement inférieur à celui obtenu dans d'autres orientations de production telles que les grandes cultures, la viticulture ou la production porcine. En combinant les trois indicateurs précités, une méthode permet enfin de répartir les exploitations bovins-lait et bovins-viande selon huit classes dites de « performances économiques ». |

| Abstract: | Uruguay recently confronted the impact of a once-in-a-century severe drought, which affected key agricultural areas, and caused significant direct losses to the agricultural sector, especially for soybean production and cattle farming - important exports in Uruguay's trade matrix. From October 2022 to April 2023, rainfall was about 47 percent below historical averages, contributing to a decline in agricultural output and impacting overall GDP growth. The frequency of recent climate shocks witnessed in Uruguay combined with its rich climate data make it the ideal candidate to understand if weather shocks matter and through which transmission mechanisms. Using the empirical and theoretical framework outlined in Gallic and Vermandel (2020) we document that weather shocks play an important role in business cycle dynamics in Uruguay. |

| Abstract: | World trade in animal products, excluding trade between member states of the European Union (EU), has risen sharply over the past two decades to reach 239 billion euros in 2022 (the highest level ever), equivalent to 17% of total agricultural and agri-food trade. With a trade balance of 49.8 billion euros in 2023, the EU is the world's biggest surplus zone for animal products, ahead of Brazil, New Zealand and Australia. Despite the proliferation of free-trade agreements and the fears they inevitably arouse, this trade balance has improved significantly, thanks above all to dairy products and pork. While a potential future agreement between the EU and Mercosur countries raises legitimate concerns, especially for beef, several other agreements already signed (Canada, South Korea, Japan, etc.) have not led to a significant increase in European imports of animal products. |
| Abstract: | Les échanges mondiaux de produits animaux, hors commerce entre les États membres de l'Union européenne (UE), ont fortement progressé au fil des deux dernières décennies pour atteindre 239 milliards d'euros en 2022 (le plus haut niveau jamais atteint), soit l'équivalent de 17 % du total des échanges agricoles et agroalimentaires. Avec une balance commerciale de 49, 8 milliards d'euros en 2023, l'UE est la zone la plus excédentaire en produits animaux, devant le Brésil, la Nouvelle-Zélande et l'Australie. En dépit de la multiplication des accords de libre-échange et des craintes que ceux-ci ne manquent pas de susciter, cette balance commerciale s'est nettement améliorée grâce surtout aux produits laitiers et à la viande porcine. Si un potentiel futur accord entre l'UE et les pays du Mercosur soulève de légitimes inquiétudes, surtout en viande bovine, plusieurs autres accords déjà signés (Canada, Corée du Sud, Japon, etc.) n'ont pas entraîné une hausse significative des importations européennes de produits animaux. |

| Abstract: | The quest for agricultural productivity has certainly increased the production, but it has come at the cost of natural resources (Egidi et al., 2022).To promote higher ecosystem services, diversifying rotations with legumes has been proposed as a viable alternative (Reckling et al., 2023). Involving local actors when designing and evaluating those alternatives can enhance their transferability and likelihood of implementation (Chopin et al., 2021). During a first workshop with local stakeholders, diversification options with grain legumes for cereal-based systems were co-designed (Hossard et al., 2024) in Greece and Spain. Using a set of agri-environmental, social and economic indicators, we assessed the performance of designed options in comparison to continuous cereal cropping. During a second workshop, stakeholders were presented with the assessment results and asked to rate i) the importance of the assessment indicators and ii) the performance of the assessed systems. In this study, we present the results of the stakeholder's ratings using an Importance-Performance matrix (IPM) that measures the satisfaction of stakeholders towards the assessed farming systems (with and without legumes) based on i) the importance of the indicators (x-axis) and ii) the agri-environmental, social and economic performance (y-axis) (Phadermrod et al., 2019). Despite the importance of economic indicators to Greek and Spanish stakeholders, they rated the economic performance of farming systems (with and without legume rotations) as low. This illustrates how important it is for stakeholders to consider the economic aspect, but legume diversification still isn't improving economic performance. In contrast, agri-environmental indicators performed largely better but are of low significance to stakeholders. Similarly, stakeholders generally placed little importance on social indicators despite rating them as highly performing. Thus, performing better in social or environmental aspects may not be sufficient to justify diversification with legumes as long as it fails to generate profitable returns. |

| Abstract: | This paper looks at the transformation of the Common Agricultural Policy (CAP) subsidies system over the period 1992 to 2023. After presenting the main stages in the structure of the CAP over the last thirty years, attention is drawn to the varying degrees of dependence of French farm income on direct subsidies. A critical analysis of the main orientations adopted for the post-2023 CAP is then proposed. |

| Abstract: | Alcohol-free wines are generally sweetened with around 40 g/L of added sugar to counterbalance sourness, which can be perceived as being excessive in such beverages. For young consumers who would consume alcohol-free products for health purposes, high levels of sugar could be an obstacle. The aim of this work was to investigate this target consumer's appreciation of fully dealcoholised Chardonnay wines containing different levels of added sugar (0, 5, 10, 20 and 40 g/L). The results showed that liking significantly increased with sugar content, and that acceptability was only achieved in the sample containing 40 g/L of added sugar, with a liking score of between 5 and 6 on a 9-point scale. Liking scores were not affected by gender, information provided to panellists (specifically that they were evaluating alcohol-free wines), and level of wine knowledge. Those who gave the highest scores were occasional wine drinkers and daily soft drink consumers. Conversely, non-wine consumers and non-soft-drink drinkers gave lower liking scores. Though these insights need to be confirmed on more samples of fully dealcoholised wine, they can assist winemakers in developing alcohol-free products and in targeting the right young consumers. |

| Abstract: | Material flow diagrams are a visual representation of sector data that allows us to visualize the size of the relative flows between the different actors. The RéfFlux project (2022-2023) is a project whose purpose was, for different French sectors represented by their technical institutes, to equip themselves with a common methodology for representing public and expert data. This article presents the common approach adopted for the creation of a common reference framework for the different plant and animal sectors in a context of great diversity of data, actors, technologies and issues. We propose a reading grid for the diagrams that can be produced, in particular those posted online on the RMT FILARMONI website via 3 types of possible thematic analyses: questions of food sovereignty and sector dependency, questions of co-product flows linked to the bioeconomy and finally adaptation to household consumption, at home and outside the home. We show how this type of tool can contribute to informing the public debate by facilitating dialogue between stakeholders. The main objective of this work is to contribute to a better understanding of the origin and future of plant and animal production in France in order to inform the choices of public policies and private decision-makers. |
| Abstract: | Les diagrammes de flux de matières sont un mode de représentation des données de filière permettant de rendre visuel les liens qui relient les acteurs entre eux et leur importance. Le projet RéfFlux (2022-2023) est un projet dont la finalité était, pour différentes filières françaises représentées par leurs instituts techniques, d'harmoniser leur approche et de se doter d'une méthodologie commune de représentation des données publiques et expertes. Cet article présente la démarche adoptée pour la réalisation d'un référentiel commun aux différentes filières végétales et animales malgré la grande diversité des données, des acteurs, des procédés de transformation et des enjeux. Nous proposons une grille de lecture des diagrammes réalisables et notamment ceux mis en ligne sur le site web du RMT FILARMONI via 3 types d'analyses thématiques possibles : les questions de souveraineté alimentaire et de dépendance des filières, les questions de flux de coproduits en lien avec la bioéconomie et enfin l'adaptation à la consommation des ménages, à domicile et hors foyer... L'objectif principal de ce travail est de contribuer à une meilleure lecture sur l'origine et le devenir des productions végétales et animales en France afin d'éclairer les choix des politiques publiques et des décideurs privés. |

| Abstract: | Farmer autonomy has become a research issue and a key factor for the farming systems transition. However, there is no consensual definition of what farmer autonomy at work is, nor any way of describing it to promote it. To contribute to this challenge, the aim of this paper is to identify the underlying dimensions of farmers' work autonomy processes, as well as the conditions that have favored or prevented it. We approach it as a process of renormalization and learning at work. To this end, we have combined two methods of data collection: individual interviews of farmers and the confrontation of an individual trajectory with the collective. In this way, we identified how important it is for these farmers to choose their own system and finding meaning, in spite of being confronted with the norms of the local environment. Participating in collectives that set new professional norms is a way of promoting transition.We have shown that their posture is a condition conducive to experimentation and renormalization. Finally, articulating renormalization theories and valuation is essential to understanding autonomy at work. These results open up avenues for reflection on designing collective training settings that mobilize individual trajectories to achieve collective and individual learning. |

| Abstract: | While individuals are expected to perceive similarly identical quantities, regardless of the used units (e.g., 1 ton or 1000 kg), several scholars suggest that consumers over-infer quantities when they are presented in bigger and phonetically-longer numbers. In two experimental studies, we examine this numerosity bias in the context of household food waste. Unlike previous scholars, manipulating numerosity revealed no effect: perceptions of food waste volume and likelihood to reduce it are not influenced by the used numeric value (2500 g vs. 2.5 kg; Study 1) nor the number of syllables (two kilos eight hundred seventy-five grams vs. three kilograms; Study 2). |

| Abstract: | While climate change is widely considered as a major challenge for societies, another pressing global environmental problem, i.e. the loss of biodiversity, is often given less attention despite its strong negative consequences for ecosystems and thus for human life. In light of the strong interconnections between biodiversity loss and climate change, this paper compares the pref-erences and stated willingness to pay (WTP) for biodiversity conservation and climate pro-tection. The empirical analysis is based on data from a broadly representative large-scale com-puter-assisted online survey of more than 9, 000 citizens in Germany in 2021. Our data reveal a strong correlation between the perceived importance of the problems of biodiversity loss and climate change as well as between the WTP for biodiversity conservation and climate protection. However, the average WTP for climate protection is slightly higher than for bio-diversity conservation according to our data. Our econometric analysis with bivariate linear and loglinear regression models as well as Tobit and binary probit models suggests that the main explanatory factors, namely environmental attitudes (i.e. environmental awareness and ecological policy identification) as well as economic preferences (i.e. altruism, trust, and pa-tience) in addition to some socio-economic variables (e.g. equivalized income), are very similar for the WTP for biodiversity conservation and climate protection. However, for many individual characteristics (e.g., ecological policy identification, altruism, trust, patience) that are (statistically) significantly correlated with the WTP for both climate protection and biodiversity conservation, the correlations are significantly stronger for the WTP for climate protection. These estimation results, in combination with a higher average perception in our sample that climate change is an important global environmental problem, could be due to the stronger recognition of climate change and protection in the public debate (e.g., in media coverage) compared to biodiversity loss and conservation. |

| Abstract: | Land use changes, and especially urbanization, significantly impact water and energy systems, and the associated greenhouse gases (GHG) emissions. However, studying the urbanization and population dynamics and quantifying their effects on coupled water-energy-emissions systems remains underexplored in certain countries. Greece, for instance, has been slow to integrate those systems into data-driven models assessing their feedbacks. To fill this gap, this research investigates these dynamics in Greece, for the period 2022-2050, by combining different modelling approaches, for the first time to our knowledge. A Remote Sensing analysis, utilizing freely available satellite data and open-source tools such as QGIS, was applied to map and monitor land use changes, including urbanization. Greece has been proved to be a particularly interesting case study as simultaneous population decline and increasing urbanization are reshaping key sectors of the developing urban centers, such as the residential and services sectors. To capture the complex feedbacks between the developing urban centers with the changing population, to their water-energy-emissions responses, we coupled the LEAP (Low Energy Analysis Platform) model with the WaterReqGCH model. Thus, the energy consumption and the associated GHG emissions were simulated along with the water consumption of the residential and the services sectors. The results reveal critical trends: population decline drives a reduction of the overall water and energy consumption, yet, despite the reducing trends, urban areas claim increasing shares of these resources over time. Similarly, GHG emissions decrease but exhibit shifts in pollutant distribution, with certain emissions holding larger shares in urban contexts. This integrated land-water-energy-emissions analysis underscores the value of holistic assessments to manage these systems sustainably, and highlights the need to develop plans considering them as a whole. The provision of detailed information on the evolution patterns and feedbacks of those systems is critical to shape integrated policies aiming at multiple benefits. By linking urbanization patterns with resource dynamics and environmental impacts, we discuss how our findings can be translated into actionable insights for sustainable urban planning and resource management strategies. |

| Abstract: | The NSSO report (2015) shows that 41 percent of the rural households in India have accessed information and 34 percent households have used them. This paper explores the households’ use of information and understand their preference of information sources and their determinants. Households with better socio-economic conditions access information and from multiple sources. Media has the highest access while public sources have the lowest. Most of the households accessing information use it but the source-wise adoption rates show that, the source with the highest access, media, has the lowest use. This study tries to identify potential factors that lead to a systematic difference in using patterns across households and also across sources. Almost 80 percent of the households accessing information have used it and those not using information have cited lack of credit as a big hurdle to adoption among other reasons. Source-wise disaggregation of use shows that media has the lowest use at around 60 percent, even though it is the highest accessed resource. For all other sources, the share hovers around 80 to 90 percent. The analysis uses a Heckman Selection model to identify the potential factors that drive information use and also the differences between users and non-users of information from media. Overall, use of information is driven more by education and availability of credit than by other factors directly. Caste doesn’t appear to be a significant determinant of use directly, but obviously through the caste dynamics that shape different outcomes like education, access to information and access to credit. This analysis finds evidence to support the existing argument that development of human capital is crucial in processing information and using it for efficiency gains. |

| Abstract: | Despite their health and environmental benefits, the share of legumes in the diets of many developed countries remains low. To support eaters towards rebalancing animal and plant proteins in their diet, catering professionals have an important role to play. The project's objective is to explore culinary students' beliefs toward legumes, taking into account their attachment to meat, which is still the reference source of protein. For this purpose, a quantitative survey was conducted on 102 culinary students. Overall, culinary students have a favourable view of legumes in terms of the environment, nutrition, restaurant operations, or consumer expectations. Two groups of students were identified based on their level of attachment to meat. Positive beliefs toward legumes are more strongly present among students with a weaker attachment to meat (36 % of the sample) than among students with a stronger attachment to meat (64 % of the sample). The results shed light on the profiles of future actors in the restaurant industry and their representations of legumes in relation to their psychological relationship with meat. |

| Abstract: | The paper explores how well the National Climate Budget (NCB), starting in 2016, has supported the climate reform agenda articulated in the National Climate Change Action Plan 2011-2028 (NCCAP), now on its 14th year. It observes that the NCB, as appropriated, grew from P175 billion in 2016 to P457.4 billion in 2024, or by 161%, with a sharp increase of P174.8 billion, or 60.3%, occurring between 2022 and 2023. However, the sharp increase in 2023 is accounted for by just two agencies - DPWH and DOTR - whose incremental climate budgets account for 98% of the increase, or P146 billion and P24 billion respectively. Moreover, the share of NCB in the primary budget was only 7.3% on average over the period, and never higher than 10% in any one year, raising doubts about a “whole-of-government†approach to addressing climate change risks and impacts. Among the seven NCCAP strategic priorities, Water Sufficiency accounts for the greatest share at an average of 63.9% of the climate budget every year. Yet recurring El Nino events, which are known to exacerbate water scarcity, continue to require the activation of an ad-hoc mechanism to “ensure the country’s readiness to fight the effects of the El Nino phenomenon†. A deeper dive into the items for Water Sufficiency indicates a budget that is almost totally allocated to flood control and other construction works of DPWH; allocations to strengthen the regulatory environment and better manage the supply and demand of water resources are negligible in comparison. Prospects for advancing water security and mitigating El Nino impacts are discussed. |

| Abstract: | We study the large-scale experimental rollout of a platform that reduced search and matching frictions in Ugandan agricultural markets by connecting buyers and sellers. Market integration improved substantially: trade increased and price gaps fell. Interpreting the experiment through a trade model, we estimate treatment effects accounting for equilibrium changes that impact control markets. The intervention reduced fixed trade costs by 21% and increased trade flows between treated markets by 6% and across all markets by 1%. Scale economies shaped engagement: few farmers used the platform, but equilibrium price convergence from improved arbitrage by larger traders passed through to farm revenue. |

| Abstract: | In Senegal, as in many countries in sub-Saharan Africa, funding constraints limit water supply, particularly in rural areas. Despite government reforms to improve access to water, major challenges remain, particularly in the groundnut basin, where poor management and climatic variations exacerbate the scarcity of water and the vulnerability of populations. In 2014, the government entrusted the management of drinking water services to the private sector through the Délégation de Services Publics (DSP), thereby promoting investment and the sustainability of water infrastructure. This study examines the impact of private sector involvement in rural water management and its role in the socio-economic development of the groundnut basin. Analysis of hydraulic data, socio-economic surveys and interviews reveals increased professionalisation and a strengthening of the drinking water supply network. This has helped to diversify sources of income and reduce socio-spatial inequalities. However, faced with tariffs that are often considered high, low-income households are developing coping strategies to meet their water needs. |
| Abstract: | Au Sénégal, comme dans de nombreux pays d'Afrique subsaharienne, les contraintes de financement limitent l'approvisionnement en eau, particulièrement en milieu rural. Malgré les réformes gouvernementales pour améliorer l'accès à l'eau, des défis importants persistent, notamment dans le bassin arachidier, où la mauvaise gestion et les variations climatiques exacerbent la raréfaction de l'eau et la vulnérabilité des populations. En 2014, l'État a confié la gestion des services d'eau potable au secteur privé à travers la Délégation de Services Publics (DSP), favorisant ainsi les investissements et la pérennité des infrastructures hydrauliques. Cette étude examine l'impact de l'implication du secteur privé dans la gestion de l'hydraulique rurale et son rôle dans le développement socio-économique du bassin arachidier. L'analyse des données hydrauliques, des enquêtes socio-économiques et des entretiens révèle une professionnalisation accrue et un renforcement du réseau d'approvisionnement en eau potable. Cette dynamique a permis de diversifier les sources de revenus et de réduire les inégalités socio-spatiales. Toutefois, face à des tarifs souvent jugés élevés, les ménages à faible revenu développent des stratégies d'adaptation pour satisfaire leurs besoins en eau. |

| Abstract: | The Comté sector, France's leading PDO cheese with an annual production of almost 70, 000 tonnes, is based on strict specifications. This regulatory framework provides a framework for agricultural and artisanal practices to preserve the identity of the product while promoting its sustainability. By incorporating measures such as limiting the size of farms, regulating workshops and conserving permanent meadows, the industry is working to achieve a balance between economic, social and environmental dimensions. This paper explores three key aspects: 1) the way in which the specifications protect the identity of the product; 2) their direct and indirect impact on sustainability, particularly through the promotion of the terroir; 3) their role in strengthening the collective ethic and the interdependence of the players. Ultimately, these measures contribute to greater resilience in the face of contemporary challenges such as climate change and growing societal expectations. In this way, the Comté sector illustrates the ability of PDO systems to reconcile tradition, innovation and sustainability. |
| Abstract: | La filière Comté, première AOP fromagère française avec une production annuelle de près de 70 000 tonnes, repose sur un cahier des charges strict. Ce cadre réglementaire encadre les pratiques agricoles et artisanales pour préserver l'identité du produit tout en favorisant sa durabilité. En intégrant des mesures telles que la limitation de la taille des fermes, la régulation des ateliers et la conservation des prairies permanentes, la filière agit pour un équilibre entre les dimensions économique, sociale et environnementale. Cette communication explore trois aspects clés : 1) la manière dont le cahier des charges protège l'identité du produit ; 2) son impact direct et indirect sur la durabilité, notamment via la valorisation du terroir ; 3) son rôle dans le renforcement de l'éthique collective et de l'interdépendance des acteurs.

| Abstract: | This study attempts to examine the impact of green brand trust and self-brand connection on green brand loyalty, with green perceived value and green transparency as antecedents. The responses were collected from and users of electric vehicles, and the proposed hypotheses were tested using Structural Equation Modeling (SEM) through SmartPLS 4. The study found that green brand trust had a significant positive impact on green brand loyalty, while the relationship between self-brand connection and green brand loyalty significant but weak. The study highlighted the importance of green perceived value as an antecedent for self-brand connection and green brand trust, which was more significant than green transparency. The study offers insights to practitioners enhancing their knowledge on formation of customer, allowing them to develop effective marketing strategies. The study recommends that companies emphasize transparency in their marketing approaches and address green challenges related to their products' environmental value. Furthermore, the study suggests that green brand loyalty may be achieved through green transparency and green perceived value, which are crucial for establishing green brand trust. |

| Abstract: | To secure and reap the benefits from GI recognition, the government’s role is necessary, but the role of producers is no less pertinent. Although twenty-eight GI products have been registered in Bangladesh, none have been exported with the GI tag yet, indicating a failure on the part of exporters to capitalise on the GI tags. Eligible businesses must contact the GI owner organisations to gain from premium export prices. |

| Abstract: | The Global Climate Hub (GCH) has been developed under the United Nations Sustainable Development Solutions Network (UN SDSN). It is an international research-led initiative for tackling complex sustainability challenges. The SDSN GCH develops national and regional pathways (optimal dynamic and spatial mixture of policies, technologies, and fiscal and financial instruments) for the transition to climate neutrality and climate resilience, using a holistic and interdisciplinary methodology: We co-design pathways for climate resilience and neutrality with stakeholders, based on the integration of downscaled climate scenarios with science-based national and regional systems modelling (energy, land and marine use systems, health and socioeconomics systems). The approach is aided by an open-access AI-driven data gathering, aggregation and visualization platform, various innovation accelerators and a training and education unit, aimed at strengthening stakeholder involvement and capacity. The work of the GCH is the result of the coordination of nine distinct research units, covering a wide range of expertise in digital applications, climate science, land, water, food, biodiversity, and marine and maritime systems, energy and decarbonization, land and maritime transport, public health, solutions� application, policy, finance, labour markets, participatory approaches, education and training. The coordinated work of these nine units provides a unique approach of holistically addressing all levels of the human-environmental interface for providing truly sustainable solutions tailored per case study or region. In this presentation, we describe for the first time how maritime operations are seen as a part of a broader sustainability framing of the nine research units of the GCH. First, the importance of "Data, Platforms and Digital Applications" (unit 1) in modelling sustainable maritime operations is outlined. Then, the actual modelling is briefly presented (unit 3), combining the use of climate change projections (unit 2), and the optimal maritime operations, considering energy-fuels-emissions models (unit 4), as well as the economy and finance tools to ensure a just transition (unit 7). Moreover, their interactions and impacts on "environment and public health" (unit 5) are discussed. To bridge science to practical application and policy, and ensure the long-term implementation, we present the role of: the "Transformative and Participatory Approaches" (unit 8) to co-design solutions with stakeholders; the "Innovation/ Acceleration" unit 6, to practically implement these solutions� and the "Education, Training, Upskilling and Reskilling" (unit 9), to develop the necessary expertise for the stakeholders to own and manage the solutions. This approach comprehensively addresses all aspects of human-environment interaction, providing comprehensive and long-lasting sustainable solutions. |

| Abstract: | The various versions of the Porter hypothesis suggest that well-designed environmental public policies may have positive effects on eco-innovation adoption and on the profitability of enterprises on the long run. However, these effects may be heterogeneous depending on the eco-innovation at stake and influenced by the other enterprises in competition. Using a repeated cross-country European survey on SME, we estimate mixed Ordered Probit with correlated random effects and sample selection. We are able to disentangle direct and indirect determinants of costs while accounting for the internal, contextual and public policies levers of ecoinnovation adoption. While testing the three versions of Porter's hypothesis, we extend previous work by taking into account the heterogeneous impact of different eco-innovations on profitability, on the one hand, and the impact of eco-innovation adoption by one firm on another, on the other hand. Our results have valuable policy implications for policymakers and SMEs. |

| Abstract: | I distinguish between reduction offsets and removal offsets, the former generated by a reduction in the rate of greenhouse gas emissions and the latter generated by the removal of greenhouse gases from the atmosphere. I show that only removal offsets make any contribution to mitigating climate change. There is a simple intuitive explanation: a firm buys an offset to compensate for the fact that it is emitting greenhouse gases and plans to continue to do so. What should “compensate” mean in this context? That the purchase of the offset undoes the negative impact of the continuing emissions on the climate. This can only happen by the removal from the atmosphere of a quantity of greenhouse gases equal to that emitted by the purchaser of the offset. So an offset which compensates for the climatic impact of emissions has to remove greenhouse gases from the atmosphere. I also review carbon offsets generated by forest management, as of all currently-traded offsets these are the closest to removal offsets. |

| Abstract: | The global Agenda for energy transition and the imperative for climate adaptation mandate a comprehensive understanding of resource use and emissions in energy systems. Industries play a pivotal role in this transformation, both as major energy consumers and as key contributors to greenhouse gas (GHG) emissions. Building climate resilience requires the inclusion of interconnected natural resources such as water in industrial planning, highlighting the need for joint energy-water assessments to develop adaptive and holistic climate mitigation strategies. This consideration is an overlooked issue in southern European countries, given their lower industrialization levels than northern Europe. However, the analysis of resource use and emissions in industrial energy systems is a particularly critical issue for southern European countries because they face significant challenges due to their drier climate, naturally limited water resources, and their high vulnerability to climate change. At the same time, there are major emitting industries in those countries as well, and the sector's energy transition largely depends on their decarbonization as well. This research addresses this gap by analyzing Greece's industrial energy, water demands, and GHG emissions, from 2022 to 2050. It breaks the industrial sector into 17 subcategories, including food and tobacco, textiles and leather, wood products, paper pulp and printing, chemicals and chemical products, rubber and plastic, non-metallic minerals, basic metals, machinery, transport equipment, other manufacturing, coke and refined petroleum products, mining, cement and steel production. The annual energy and water consumption alongside GHG emissions were estimated, by coupling the Low Emissions Analysis Platform (LEAP) model with the WaterReqGCH model. Such integrated assessments are essential for informed policy evaluation and decision-making. Further, we evaluate the Greek National Energy and Climate Plan, showing its potential to shape a more sustainable industrial sector, considering its effects on the simulated water-energy-emissions system. Findings reveal critical synergies, trade-offs, and gaps, emphasizing the necessity of co-considering water resources into energy planning, developing thus more holistic pathways. |

| Abstract: | World trade in poultry meat (all species, including preparations and cured meats), excluding intra-European Union (EU) trade, reached 22.3 million tce in 2022, worth 31.6 billion euros, the highest level ever. This increase in trade, dominated by exports from Brazil, the United States, the EU and Thailand, is taking place against a backdrop in which global consumption of poultry meat has doubled since 2000. The main importers are China, Japan, the UK and the EU. The EU's poultry meat trade balance remains positive (2.3 billion euros in 2023), thanks to sustained exports to the UK market and despite increased imports from Ukraine. Within the EU, Poland stands out with a four-fold increase in production and a rapid rise in exports in two decades. In France, the sector's economic trajectory is unfavorable, with imports accounting for 44 % of domestic consumption. Using three databases (BACI, COMEXT and French customs), this article summarizes the evolution of world, European and French trade in poultry meat. |
| Abstract: | Le commerce mondial de viande de volailles (toutes espèces confondues, préparations et viandes saumurées incluses), mesuré hors échanges intra-Union européenne (UE), s'est élevé à 22, 3 millions de tec en 2022 pour un montant de 31, 6 milliards d'euros, le plus haut niveau jamais atteint. La hausse de ces échanges, dominés à l'export par le Brésil, les États-Unis, l'UE et la Thaïlande, intervient dans un contexte où la consommation mondiale de viandes de volailles a doublé depuis 2000. Les principaux importateurs sont la Chine, le Japon, le Royaume-Uni et l'UE. La balance commerciale de l'UE en viande de volailles demeure toujours positive (2, 3 milliards d'euros en 2023) grâce aux exportations soutenues vers le marché britannique et en dépit d'importations accentuées en provenance de l'Ukraine. Au sein de l'UE, la Pologne se distingue avec un quadruplement de sa production et un essor rapide de ses exportations en deux décennies. En France, la trajectoire économique de cette filière est défavorable avec des importations qui représentent 44 % de la consommation intérieure. En valorisant trois bases de données (BACI, COMEXT et douanes françaises), cet article propose une synthèse sur l'évolution du commerce mondial, européen et français de viande de volailles. |

| Abstract: | The use of bio-connected devices (BCDs) in medicine and perishable logistics marks a significant advancement in product traceability and flow security. These devices, equipped with heat-sensitive biosensors, allow for real-time monitoring of storage and delivery conditions. This ensures that medicines, particularly vaccines, and perishable goods are kept within proper temperature ranges, preventing deterioration. Additionally, BCDs play a crucial role in combating counterfeiting through transparent traceability systems, often enhanced with blockchain technology, which guarantees product authenticity throughout the supply chain. However, the adoption of these innovative technologies faces several barriers, including high initial costs, data security concerns, and the need for adequate technical infrastructure. Despite these challenges, BCDs have substantial potential to transform the food and pharmaceutical industries by boosting operational efficiency and ensuring product safety. |
