Purpose: The paper aims to examine interactions between demonstrations at programme level and Agricultural Advisory Services (AAS). It situates analysis of the demonstration programme activities within contemporary advisory contexts, asking: how do demonstration programmes interact with the AAS in which they are situated; and what role do demonstration programmes play in enhancing and contributing to the AAS? Methodological approach: Data, pertaining to organisational arrangements, were collected using interviews and workshops representing 35 demonstration programmes across Europe. Themes from the literature together with emergent themes were used to progressively unpack and understand the interaction between the programmes and the AAS. Findings: Demonstration organisational arrangements show different degrees of embedding in, and adapting to, the AAS. Embedding is being incorporated into existing formalised structures and is more likely in the AAS with a low level of pluralism. Adaptation occurs through collaboration, partnership and networking and is more likely in more pluralistic AAS. Practical Implications: The need to support demonstration programmes to create more stable networks, to strengthen their linking role in the AAS, and to foster strategies for the progression of farmers' learning was identified. Theoretical implications: The paper contributes to the literature by providing insights at the demonstration programme level (as opposed to farm or event level) and revealing embedded and adaptive processes with many interdependencies between the programmes and AAS components. Originality: This paper opens up new perspectives on understanding how demonstrations are positioned in contemporary AAS contexts, looking at AAS influences on delivering demonstrations beyond farm and event level methods.

The profound influence of climate change on the hydrological cycle raises concerns about its potential impacts on water quality, particularly in agricultural catchments. Here, we analysed 200 storm events monitored for nitrate and total phosphorus (TP) at sub-hourly intervals from 2016 to 2023 in the Kervidy-Naizin catchment (north-western France). Using Extreme Value theory, we identified storm events with extreme concentrations and compared their hydroclimatic characteristics to those of non-extreme events. We hypothesised that extreme concentration events occurred under extreme hydroclimatic conditions, which are projected to become more frequent in the future. The extreme events identified showed dilution patterns for nitrate, with concentrations decreasing by up to 41 %, and accretion patterns for TP, with concentrations increasing by up to 1400 % compared to non-extreme events. Hydroclimatic conditions during extreme concentration events were characterised by high rainfall intensities and low antecedent discharge, but no particular conditions for mean discharge. During non-extreme events, nitrate concentration-discharge relationships exhibited primarily clockwise hysteresis, whereas TP displayed an equal mix of clockwise and anticlockwise loops. In contrast, extreme events showed more anticlockwise hysteresis for nitrate and weak hysteresis for TP. We interpreted these dynamics and their hydroclimatic controls as the result of infiltration-excess overland flow diluting nitrate-rich groundwater and exporting large amounts of TP during intensive rainfall events following droughts, while groundwater fluctuations in the riparian zone and streambed remobilization control nutrient exports during non-extreme events. Given the increasing frequency and intensity of hydroclimatic extremes, such retrospective analyses can provide valuable insights into future nutrient dynamics in streams draining agricultural catchments., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Parcel-scale crop classification utilizing time-series satellite observations is of significant importance in precision agriculture. The prior knowledge that crop types can be organized in a hierarchical tree structure is beneficial for improving crop classification. Moreover, the crop hierarchy aligns with the coarse-to-fine cognitive process of geographic scenes. Based on the crop hierarchy, this study developed a general hierarchical classification framework for enhancing crop mapping using time-series Sentinel-1 data. Central to this method is a deep-learning-based hierarchical classification model that explores and makes use of crop hierarchical knowledge. First, preprocessed Sentinel-1 data were geometrically overlaid onto farmland parcel maps to derive parcel-scale time-series features. Second, we constructed a hierarchical crop type system for study areas based on the crop phenology of labeled crop-type samples. Third, we developed a deep-learning-based hierarchical classification model to identify crop types for each parcel, to generate final crop-type classification maps. The proposed approach was further discussed and verified through the implementation of parcel-scale time-series crop hierarchical classifications in a study area in France with farmland parcel maps and time-series Sentinel-1 data. The classification results, indicating significant improvements greater than 4.0% in overall accuracy and 5.0% in F1 score over comparative methods, demonstrated the effectiveness of the proposed method in learning multi-scale time-series features for hierarchical crop classification utilizing Sentinel-1 data sequences., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Zhou Ya'nan reports financial support was provided by the Third Xinjiang Scientific Expedition Program.

As many contaminated agricultural soils can no longer be used for food crops, lignocellulosic energy crops matter due to their ability to grow on such soils and to produce biomass for biosourced materials and biofuels, thereby reducing the pressure on the limited arable lands. Sorghum bicolor (L.) Moench, can potentially produce a high biomass suitable for producing bioethanol, renewable gasoline, diesel, and sustainable aircraft fuel, despite adverse environmental conditions (e.g. drought, contaminated soils). A 2-year field trial was carried out for the first time in the northern France for assessing sorghum growth on a Cd, Pb and Zn-contaminated agricultural soil amended with humic/fulvic acid, alone and paired with arbuscular mycorrhizal fungi. Sorghum produced on average (in t DW ha -1 ): 12.4 in year 1 despite experiencing a severe drought season and 15.3 in year 2. Humic/fulvic acids (Lonite 80SP®) and arbuscular mycorrhizal fungi did not significantly act as biostimulants regarding the shoot DW yield and metal uptake of sorghum. The annual shoot Cd, Pb and Zn removals averaged 0.14, 0.20 and 1.97 kg ha -1 , respectively. Sorghum cultivation and its metal uptake induced a significant decrease in 0.01 M Ca(NO 3 ) 2 -extractable soil Cd, Pb and Zn concentrations by 95%, 73% and 95%, respectively, in year 2. Soluble and exchangeable soil Cd, Pb and Zn would be progressively depleted in subsequent crops, which should result in lower pollutant linkages and enhanced ecosystem services. This evidenced sorghum as a relevant plant species for phytomanaging the large area (750 ha) with metal-contaminated soil near the former Pb/Zn Metaleurop Nord smelter, amidst ongoing climate change. The potential bioethanol yield of the harvested sorghum biomass was 5589 L ha -1 . Thus sorghum would be a promising candidate for bioethanol production, even in this northern French region., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Grasslands are essential habitats for preserving arthropod communities in agricultural landscapes. The environmental state of grassland, their farming practices, and land cover heterogeneity in landscape around grassland are three factors that influence ground-dwelling grassland arthropod communities. However, the impact of the intensity of farming practices at the landscape scale has not yet been fully explored. In this study, (i) we studied complex relationships between environmental variables that describe the local conditions (i.e., grassland environmental state and farming practices) and land cover heterogeneity (i.e., land cover and landscape-wide intensity) of our study area in north-east France; and (ii) estimated the relative effect weight of landscape-wide intensity compared to other local and landscape variables on arthropod communities. We identified 14 taxonomic families, with Lycosidae, Carabidae and Staphylinidae as the families most represented in communities. We have highlighted a positive correlation between the different variables of landscape-wide intensity, as well as a positive correlation between sampled grassland intensity and the quantity of grassland in the landscape. Using Partial Least Squares Path Modelling (PLS-PM) analysis, we observed a positive effect of landscape-wide intensity on arthropod abundance-activity in grassland, indicating a potential concentration effect in the grasslands surrounded by an intensive landscape. Also, we have shown that the effect of landscape-wide intensity was at least as strong as that of other local and landscape variables. Our study is one of the first to consider land cover and farming practices simultaneously at the landscape scale. We demonstrate the importance of considering farming practices at the landscape scale to explain the state of ground-dwelling arthropod communities, and the need to take them into account when designing landscapes that are favourable to biodiversity. We argue that further studies are needed to explain the mechanisms involved in the relationship between arthropod communities and farming practices at the landscape scale., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Purpose: We investigate how the structural conditions of eight different European agricultural innovation systems can facilitate or hinder collaboration and social learning in multidisciplinary innovation networks. Methodology: We have adapted the Innovation System Failure Matrix to investigate the main barriers and enablers eight countries (England, France, Germany, Hungary, Italy, Latvia, The Netherlands and Switzerland). Findings: Results show some of the recent trends the AKS actors in these countries have experienced and how these have affected their potential to act as collaborators in multidisciplinary innovation networks. Lack of funds, combined with horizontal and vertical fragmentation and the lack of proper evaluation criteria for collaborative innovation networks are among the most important threats we found. Practical Implications: This study shows that each national AIS has some unique features. This means that the implementation of policies promoting collaboration and social learning (e.g. the European Innovation Partnerships and Operational Groups) should depend on a critical reflection of the existing structural elements of the AIS in each country and whether there is a need for inclusion of new actors, or whether certain innovations for collective goods should be promoted. Originality: The paper contributes to the ongoing discussion in the scientific literature on the advantages and disadvantages of privatization of extension and advisory services and the shift from thinking in terms of the traditional Agricultural Knowledge System towards a broader Agricultural Innovation System.

This paper assesses the environmental ambition of 2023-2027 Common Agricultural Policy in France. Since conditionality and agri-environment-climate measures are only marginally improved relative to the previous period, attention is focused on the new environmental instrument of the eco-scheme that in France targets the whole farm. Results suggest low environmental progress since almost all French farms would reach the standard level of the eco-scheme by one of the three access paths with unchanged farming practices, and 85% of them would reach the superior level. The percentage of farms at the superior level would be lower for farms specialized in annual crops than for cattle farms. We then show that the payment difference of €20 per hectare between the standard and superior level is probably insufficient for farms specialized in cereals, oilseeds and protein crops to offset the additional cost of the change in farm practices required to move from the standard to the superior level.

Though mares were essential to the breeding of medieval warhorses, they are elusive in written and iconographic sources dominated by male horses. When they appear, their portrayal is ambiguous: thirteenth-century encyclopaedists describe them both as an ideal representation of motherhood and as lascivious beings. This may have influenced the perception of mares in the context of equine husbandry. This paper compares descriptions in thirteenth-century encyclopaedias to French versions of Rufus's De medicina equorum (1250), and to its 1456 reinterpretation by Guillaume de Villiers. The Roman d'Alexandre (1180) by Alexandre de Paris, and the financial records of Charles VI (1368-1422) are used to understand the complex cultural perception of mares. Despite negative sexual undertones, mares were portrayed as strong and independent, eliciting wariness and admiration. [ABSTRACT FROM AUTHOR]

This paper presents the way the digital transformation of the agricultural sector is implemented in Europe and in France. It describes the main European and national strategies, the structure of research and innovation initiatives, and the investment in capacity building to foster innovation, adoption and use. More specifically, the French research and innovation ecosystem on digital agriculture is described. The actors involved come from different organisations, such as research and higher educational institutes, government agencies, agricultural technology (AgTech) companies, farmer unions etc., and work together by means of associations (e.g. Robagri), networks (e.g. RMT Naexus, DigiFermes, Fermes Leader), or living labs (e.g. Occitanum) on both digital technology assessment and co-design. Additionally, support is devoted to capacity building (e.g. Le Mas numérique , Mobilab) and a better understanding of the drivers of adoption and use of digital technologies (e.g. FrOCDA). Among these various organisations, #DigitAg, the Digital Agriculture Convergence Lab, has been created to foster interdisciplinary research on digital agriculture. All these initiatives aim to use digital technologies to support the European Green Deal, Farm-to-Fork and Biodiversity strategies as well as the French orientation towards more agroecological practices for safer and more sustainable food systems. Even though this organisational ecosystem is developing fast, the objective of encouraging the coevolution of both digital and green transformations is not without challenges that still need to be overcome, either through new research, innovations, initiatives or collaborations between the actors involved. Worldwide, agriculture is facing the challenges of digital and green transformations of its practices. This article describes how, in Europe and in France, an organisational ecosystem is developing to tackle these transformations in digital agriculture and facilitate their coevolution. Through European and national strategies, the structuring of research and innovation initiatives and capacity building, we describe how organisations are investing in the creation and deployment of digital technologies and solutions for safer and more sustainable food systems.

In this discussion piece, eight scholars in geography, urban planning, and agri-food studies from the United States (US) and France engage in a bi-national comparison to deepen our collective understanding of food and land justice. We specifically contextualize land justice as a critical component of food justice in both the US and France in three key areas: access to land for cultivation, urban agriculture, and non-agricultural forms of food provisioning. The US and France are interesting cases to compare, considering the differences and similarities in their colonial and agricultural histories, persistent and systemic race and class-based inequities in land access, and the roles of public bodies and social movements. In this paper, we synthesize literature, share reflections, and offer directions for future scholarship, including a broader comparative research agenda. An important difference we found is in the degree of scholarly attention to race and how it mediates access to land. We also observe that few scholars articulate a clear definition of justice in their work, nor do they share a common justice framework. We hope that this paper contributes to a more robust food and land justice framework for the use of scholars, practitioners and activists. [ABSTRACT FROM AUTHOR]

Capacity utilization (CU) measures may show the potential for production growth under improved availability of the (variable and fixed) inputs. However, the environmental constraints should be considered when taking the production decisions. These questions are important in the context of the agricultural sector that needs to ensure food security and sustainability. This paper proposes a novel approach that integrates weak disposability technology with observation-specific abatement factors with input- and output-orientated capacity utilization measures in the short and long run. The case of European Union agricultural sector is analyzed. The results indicate that the multiple output-oriented CU measures considered in the study yield often conflicting results. Italy, Germany and France show the highest levels of the agricultural capacity utilization. At the other end of spectrum, the underdeveloped economies often showed lower values thereof. The inclusion of the energy-related GHG emission in the model generally reduced the performance gaps among the countries considered. Results of the research are important in assessing the possibilities for sustainable agricultural growth and development in the European Union as the CU levels may vary for a certain depending on the inclusion of the environmental pressures in the model., (Copyright © 2022 Elsevier Ltd.

This paper investigates the role of provincial government officials concerning agricultural reform in eighteenth-century French print culture. Recent historiography has argued that reform-minded officials were active in shaping public opinion. A growth in print publications fed public interest and allowed officials a space to work out ideas for the implementation of new projects concerning agronomy. Indeed, in the second half of the eighteenth century, officials negotiated reform rather than imposing it. Letters to the editor printed in late eighteenth-century newspapers (known as affiches) provided a forum for debate among writers from diverse backgrounds. Provincial officials, especially mayors and intendants, were active participants in such published conversations. Indeed, officials wrote to the paper to stimulate public conversations for social and agricultural reform in much the same way they posed questions for essay contests held by provincial Académies. Through how-to letters, administrators offered advice about agricultural improvement. The press acted as a critical conduit to work out practical problems. For the readers of the affiches, agricultural reform was situated within a more widespread practice of observation and experimentation at the heart of the Agricultural Enlightenment.

In the last decade, many SAR missions have been launched to reinforce the all-weather observation capacity of the Earth. The precise modeling of radar signals becomes crucial in order to translate them into essential biophysical parameters for the management of natural resources (water, biomass and energy). The objective of this study was to demonstrate the capabilities of two statistical algorithms (i.e., multiple linear regression (MLR) and random forest (RF)) to accurately simulate the backscattering coefficients observed over bare agricultural soil surfaces. This study was based on satellite and ground data collected on bare soil surfaces over an agricultural region located in southwestern France near Toulouse. Multi-configuration backscattering coefficients were acquired by TerraSAR-X and Radarsat-2 in the X- and C-bands, in co-(abbreviated σ0HH and σ0VV) and cross-polarization states (abbreviated σ0HV and σ0VH) and at incidence angles ranging from 24° to 53°. Models were independently calibrated and validated using a ground dataset covering a wide range of soil conditions, including the topsoil moisture (range: 2.4–35.3%), root-mean-square height (range: 0.5–7.9cm) and clay fraction (range: 9–58%). Higher-magnitude correlations (r) and lower errors (RMSE) were obtained when using RF (r values ranging from 0.69 to 0.86 and RMSE from 1.95 to 1.00 dB, depending on the considered signal configuration) compared to MLR (r values ranging from 0.58 to 0.77 and RMSE from 2.22 to 1.24 dB). Both surpass the performance presented in previous studies based on either empirical, semi-empirical or physical models. In the linear approach, the information is mainly provided by the surface moisture and the angle of incidence (especially in the case of co-polarized signals, regardless of the frequency), while the influence of roughness or texture becomes significant for cross-polarized signals in the C-band. On the contrary, all the surface descriptors contribute in the approach based on RF. In future work, the use of the RF algorithm developed in this paper should improve the estimation of soil parameters. [ABSTRACT FROM AUTHOR]

It has recently been observed, that a change in the crop spectrum happened during the so-called Middle Neolithic in France at ca. 4000 BC. An agricultural system based on free-threshing cereals (naked wheat and naked barley) seems to shift to one based on glume wheats. This is a major change for traditional farmers and this paper aims to shed light on its possible causes. Here we describe the results of new investigations in a key area for the understanding of this process: the NW Mediterranean arch, where free-threshing cereals are the main cultivars since ca. 5100 BC. New data confirm that the shift towards glume wheats is also observed in some sites of the NE of the Iberian Peninsula and that among the glume wheats that spread at ca. 4000 BC we should not only consider emmer and einkorn but also Timopheevi's wheat. Stable isotope analyses indicate no major decrease in soil fertility or alterations in local precipitation regimes. The agricultural change may be the result of a combination of the spread of damaging pests for free-threshing cereals and presumably new networks being developed with the North-eastern part of Italy and the Balkans.

Long criticized, pluriactivity is now perceived as an alternative agricultural strategy and it is becoming a subject of support policies. However, having an off-farm job generates organizational issues that can penalize the viability of this strategy. In this paper, we study the initial motivations of pluriactivity and the strategies developed by farmers over time to handle pluriactivity difficulties and we examine conditions that lead to permanent pluriactivity or not. We use an original qualitative approach interviewing 29 pluriactive farmers in "Nord-Pas de Calais", region located in northern France. Our results show that pluriactivity is a dynamic strategy and farmers develop different strategies to adapt their pluriactivity over time to their farm requirements and time constraints. We find that most of the trajectories lead to a permanent pluriactive status, but pluriactivity lasts longer when both activities adapt to each other. [ABSTRACT FROM AUTHOR]

The paper aims at better understanding the micro-foundations of current institutional changes in agricultural knowledge and innovation systems (AKIS). A survey of 98 farmers and interviews with 37 advice providers in south-western France were conducted to analyse the ways in which farmers combine different sources of advice (microAKIS). The farmers' practices were observed for general farm management and for 3 types of innovation (new crop diversification, digital decision support tools, and labour outsourcing). The results highlight poorly-known characteristics of microAKIS regarding the variety of sources of advice used by farmers, and the limited number of reliable resources on which farmers can draw at key stages of the innovation process. They provide evidence of bottom-up mechanisms of institutional changes such as the routinization of the use of certain service providers that are often overlooked in AKIS analyses (e.g. upstream industries). These results can contribute to reducing the misalignments of stakeholders' representations of AKIS and microAKIS, and therefore facilitate public debates and improve the efficiency of interventions in this area. Studies of institutional changes resulting from the evolution of microAKIS are expected to complement analyses of increased pluralism of advice providers. Linking the observation of microAKIS and the analysis of incremental institutional changes in AKIS allows the identification of transformations of the AKIS rationale that would otherwise remain partially invisible.

Featured Application: This paper presents a smart irrigation context-aware system to be applied on an experimental farm in France. The experimental farm is an ecosystem for agricultural machines and digital information systems developed by an alliance of European organizations and institutes. Moreover, the two ontologies proposed by this paper, CASO and IRRIG, are open access and have the potential to be used by other applications such as smart buildings or smart cities. The rapid development of information and communication technologies and wireless sensor networks has transformed agriculture practices. New tools and methods are used to support farmers in their activities. This paper presents a context-aware system that automates irrigation decisions based on sensor measurements. Automatic irrigation overcomes the water shortage problem, and automatic sensor measurements reduce the observational work of farmers. This paper focuses on a method for developing context-aware systems using ontologies. Ontologies are used to solve heterogeneity issues in sensor measurements. Their main goal is to propose a shared data schema that precisely describes measurements to ease their interpretations. These descriptions are reusable by any machine and understandable by humans. The context-aware system also contains a decision support system based on a rules inference engine. We propose two new ontologies: The Context-Aware System Ontology addresses the development of the context-aware system in general. The Irrigation ontology automates a manual irrigation method named IRRINOV®. These ontologies reuse well-known ontologies such as the Semantic Sensor Network (SSN) and Smart Appliance REFerence (SAREF). The decision support system uses a set of rules with ontologies to infer daily irrigation decisions for farmers. This project uses real experimental data to evaluate the implementation of the decision support system. [ABSTRACT FROM AUTHOR]

This paper examines how food planning policies address the reterritorialization of agricultural activities (RAA), a crucial component of local food systems. While food planning as an integrated local policy promoting local food systems has gained increasing research attention, most of the research has been urban-centric, resulting in a limited understanding of how it includes RAA. This paper fills this research gap by assessing 39 food planning projects in France, where the state defines food planning by national law and supports local projects. Through document analysis and semi-structured interviews, RAA-associated food planning policy goals, instruments, and agri-food professional actors' involvement are identified. The empirical findings highlight the central role of RAA in French food planning projects; it either serves as the primary motivation behind these projects or evolves into a substantial component as the projects develop. A wide range of policy instruments with local innovation to support RAA are identified, with more frequent use of informational and economic than regulatory and coercive instruments, and more focus on economic development than on ecological transition. Minority and majority farmers' organizations are involved in food planning processes with varying degrees of engagement across territories, reflecting local governance strategies. The analytical methods in this study may contribute to future research to better comprehend RAA in local food policymaking. The systematic overview of RAA-associated food planning measures also offers insights to policymakers in other contexts regarding food policy design. The paper concludes by arguing that food planning extends beyond urban food supply; it also presents an opportunity to leverage RAA for rural revitalization and transformation, in terms of production models, rural-urban links, and local governance. • Systematic analysis of 39 projects offers an overview of French food planning. • French food plans favor economic and informational over regulatory measures. • Food planning instruments prioritize economic development over ecological transition. • French food planning engages diverse actors; both major and minor farmer groups participate.

Extreme droughts have a strong impact on agricultural production. In France, the 2003 drought generated records of yield losses at a national scale for grassland (more than 30%) and for cereals (more than 10% for soft winter wheat and winter barley). These extreme events raise the question of farm resilience in the future. Studying them makes it possible to adapt risk management policy to climate change. Therefore, the objective of this paper was to analyze the frequency and the intensity of extreme drought in 2050 and their impact on crop yield losses (grassland and cereals) in France. We used the DOWKI (Drought and Overwhelmed Water Key Indicator) meteorological index based on a cumulative water anomaly, which can explain droughts and their consequences on agricultural yield losses at a departmental scale. Then, using the ARPEGE-Climat Model developed by Meteo-France, DOWKI was projected in 2050 and grassland, soft winter wheat, and winter barley yield losses were simulated. The results compare the frequency and intensity of extreme droughts between the climate in 2000 and 2050. Our results show that the frequency of extreme droughts (at least as intense as in 2003) doubled in 2050. In addition, the yield losses due to 10-year droughts increased by 35% for grassland and by more than 70% for cereals. [ABSTRACT FROM AUTHOR]

This paper addresses the appropriation in Old Regime France, the First French Republic, and the nascent United States of the ritual wherein at the start of the agricultural season the Chinese Emperor ceremonially drove the plow. It argues that this cultural transfer insinuated Chinese ideals of political sovereignty into the highest political levels in Europe and the United States, even as it effaced references to China. Overturning traditional art historical definitions of chinoiserie, it posits instead dynamic, dialectical processes of cultural exchange whose scope of cultural transfer is not restricted to what can be identified through comparisons of style and iconography.

The population genetic structure of crop pest populations gives information about their spatial ecology, which helps in designing management strategies. In this paper, we investigated the genetic structure of the Mediterranean Corn Borer (MCB), Sesamia nonagrioides Lefèbvre (Lepidoptera: Noctuidae), one of the most important maize pests in the Mediterranean countries, using microsatellite markers for the first time in this species. Insects were collected in twenty-five locations in southwest and southeast France from cultivated and wild host plants (Zea mays, Sorghum halepense and Typha domingensis). Contrary to what has been reported so far in France, we found that MCB populations could be locally abundant on wild poales plants. Analysis was carried out at 11 polymorphic microsatellite markers. Molecular variance was significantly determined by geography, then by host plant, with 17% and 4%, respectively, when considered as a major effect, and with 14% and 1%, respectively, when considered as a marginal effect in permutational analysis. Multidimensional scaling (MDS) and GENELAND Bayesian clustering suggested that populations infecting wild plants (T. domingensis and S. halepense) were more structured locally than those affecting cultivated maize. In S. halepense, significant Isolation By Distance (IBD) indicated that this factor could explain genetic differentiation of the moth populations. In T. domingensis, local population differentiation was strong but did not depend on distance. The implication of this absence of population structure in maize and the heterogeneity of population genetics patterns in wild plants are discussed in the context of the population dynamics hypothesis and population management strategies., Competing Interests: The authors have declared that no competing interests exist.

New plant macrofossil studies in northwestern France enable a better insight into agriculture through the Bronze and Iron Age. Most of the previous analyses, carried out in Calvados (Normandy) on Late Iron Age dwellings, suggested distinctive characteristics such as the increase of Avena (oat) and the abundance of pulses in storage pits. The collection of a new database with 25 sites was done in response to the previous lack of studies, which became an issue in Brittany, Normandy and the Loire region, which are known for their western location and trade links throughout Europe. This paper deals with farming practices and their changes during the Bronze and Iron Ages. The aim was to gather new evidence related to sowing times, tilling of fields and fertility management of soils in order to discuss extensive or intensive cultivation in northwestern France. The crop cultivation techniques were investigated by studying the weed flora composition according to the FIBS approach (Functional interpretation of botanical survey). The results reveal combinations of evidence and a pattern of intra-regional diversity. [ABSTRACT FROM AUTHOR]

Objectives: Persian walnut (Juglans regia L.), the walnut species cultivated for nut production, is grown worldwide in temperate areas. In this work, chronological phenotypic data have been collected regarding a part of the walnut genetic resources of the French National Institute for Agricultural Research (INRA) of Bordeaux. Using a well described ontology, these data have been collected in order to assess the phenotypic variations among the accessions, and to better manage the germplasm collection. These data can also be helpful for any breeding program as they provide a clear phenotypic characterization of the main cultivars., Data Description: This paper introduces a dataset collected for 150 J. regia accessions for a period from 1965 to 2016, and for 3 observation sites, released as comma separated value spreadsheet. It includes observations about phenological traits (e.g. flowering dates), traits related to in-shell walnut (e.g. weight and size), and traits related to kernel (e.g. color). It can be used by other researchers particularly for multi-site phenological studies in the context of climate change since climate data files are also available. In addition, a complete walnut ontology was deposited in this repository and can assist to standardize the management of any walnut germplasm collection.

Semi-natural habitats (SNHs) are essential to biodiversity and agroecological conservation. The impact of agricultural policies on the development of SNHs is a matter of substantial importance. This study conducted a comparative analysis to examine the variations of SNHs' quantity, landscape quality, and ecosystem services resulting from the differentiated agricultural policies in China and the EU from 1990 to 2020. The Yangtze River Delta region (YRD) in China and France was selected as the study area. The results revealed that France exhibited a higher proportion of SNHs, along with improved connectivity and diversity in its plains, whereas SNHs in the YRD were limited in quantity and characterized by unstable landscape structure and ecosystem services. Both the YRD and France experienced a shift in the declined SNHs towards higher altitudes. There was noticeable landscape fragmentation and degraded ecosystem services in the hilly areas of YRD and the high plains of France. The agricultural policies of the EU achieved limited success in protecting SNHs, while China's agricultural landscapes were rapidly losing SNHs due to the absence of policy support. Based on these, the paper puts forward some countermeasures and suggestions for developing SNHs in China and the EU. Our study contributes to the global effort for agroecological conservation. • Comparative analysis of SNHs in China and the EU from 1990 to 2020. • Both YRD and France experienced a shift in declining SNHs towards higher altitudes. • Limited success of EU agricultural policies in SNH protection over three decades. • Rapid loss of SNHs in China's agricultural landscape.

This paper combines conceptual thinking and empirical analysis of landscape labelling as a new governance approach. With the help of a literature review and qualitative interviews, we (1) explore the conceptual orientation of landscape labelling, (2) analyse existing approaches in Europe and (3) elaborate its potential for integrated landscape management on a regional scale. Governance analysis to identify fostering and hindering factors is carried out for regional brands in biosphere reserves in Germany, geographic indication in Spain, organic agriculture in France and a community forest in England. We argue that landscape labelling can highlight the multitude of landscape functions and values, target a broader range of stakeholders and act as a boundary object and exchange platform for rural transformation, experimentation and learning. However, landscape labels are no panacea, but one approach within policy mixes that depend on supportive governance structures and stakeholders. [ABSTRACT FROM PUBLISHER]

The "Living Lab" (LL) model of innovation practices is increasingly applied and strongly supported by innovation policies in the agricultural sector. But while the main principles of LLs imply specific approaches to collectively implementing open innovation processes, few studies have developed an understanding of the different ways of doing so, in relation to the experimental practices on which they rely. While the specificities of agricultural LLs are beginning to be described, little is known about how they more particularly reconfigure experimentation in agricultural innovation systems. The purpose of this paper is to investigate the diversity of experimentation practices in agricultural LLs. It looks at how these practices correspond to different contextualized appropriations of an open innovation model, as translated into key principles for LL implementation. First, we produced an analytical framework that combines the principles of the LL model as described in the LL literature with generic dimensions of experimentation as analyzed in Science and Technology Studies. Second, we used this framework to analyze the diversity of experimentation practices in eighteen cases of LLs in the agricultural and food sectors. Cases were analyzed via two approaches: 1- three small and recent ongoing LLs located in France were studied during a one-year immersive observation; and 2- a collection of 15 other cases (identified in scientific and technical literature, each case corresponding to experiments that are forms of appropriation of the LL model of innovation, sometimes in several similar LLs) were analyzed, mostly based on scientific papers (describing the LLs or their outcomes), technical documents and available information such as videos online, with additional visits and discussions with LL actors for a subset of cases. Our results enable us to characterize three ideal-types of experimentation practices within agricultural LLs: 1- experimentation as a game of creativity in a predefined space; 2- experimentation as a progressive contextual adaptation for innovation adoption; and 3- experimentation as a catalyst for long-term local collective action. Each ideal-type corresponds to a particular combination of ways of (i) controlling what happens within the experimentation space, (ii) defining a perimeter for experimentation, (iii) integrating plural knowledge in problematization, and (iv) integrating various actors' evaluations of experiments. Beyond a clear distinction among ideal-types, appropriations of the LL model reveal different ways of anchoring the experimental process in an explicit temporality and situation, and of considering the construction of the LL itself as experimental and open-ended. Our analytical framework opens a new way to distinguish between various experimentation practices claiming to develop open innovation processes in agriculture. The three ideal-types that we have identified show the need to pay attention to the relation between collective experimentation practices and the LL expected outcomes. [Display omitted] • Many Living Labs are developed as new models of and for innovation processes in the agricultural sector, and transform experimentation practices. • A new analytical framework of experimentation practices within agricultural Living Labs is developed and applied. • Three widely different ideal types of experimentation practices within agricultural Living Labs are identified and described. • These ideal types promote reflexivity on the processes and outcomes targeted by actors implementing agricultural Living Labs. • Our analysis offers an understanding of how products and outcomes of innovation processes relate to experimentation practices.

The permanence of land management practices adopted under agri-environmental schemes (AESs) is often questioned. This paper investigates the drivers of farmers' decisions as to whether to maintain "proenvironment" practices beyond the duration of a contract, and in particular the effect of social norms. Our results, based on the stated intentions of 395 French farmers, show that both pecuniary and nonpecuniary motivations drive farmers' decisions, which are also significantly influenced by information about a social norm. Therefore "nudging" farmers, by conveying information to them on other farmers' proenvironmental practices, appears to be a means of maintaining the long-run benefits of AESs. [ABSTRACT FROM AUTHOR]

Proponents of short food supply chains (SFSC) have lauded their environmental benefits. Nevertheless, most studies on SFSCs have focused on their climate impact, while the synthetic pesticide use by farmers participating in SFSCs has received little research attention. In this study, we investigate the effect of farmers' involvement in different SFSC channels on synthetic pesticide use and crop yields. This study relies on data obtained from the 2020 French agricultural census and a 2018 French national survey on the phytosanitary practices of representative market gardeners. This paper uses a multinomial endogenous treatment effect model in order to account for endogeneity. We demonstrate that the effect of SFSC participation on farmers' synthetic pesticide use varies depending on the type of SFSC channel employed. Farmers who sell part of their vegetable crops through direct-to-consumer (DTC) channels use significantly fewer synthetic pesticides than those who only sell their crops through long food supply chains (LFSC). However, there is no evidence that farmers involved in direct-to-retailer (DTR) channels use significantly fewer synthetic pesticides. In addition, we have not found any evidence that SFSC participation decreases crop yields. [ABSTRACT FROM AUTHOR]

Agro-climatic indicators (AgcIs) provide a suitable tool to evaluate the implications of climate change on agriculture by simplifying plant–climate interactions. However, developing reliable AgcIs requires high-quality historical climate datasets. Consequently, reanalysis products (RPs) are frequently used as a potential reference dataset for observed climate in agricultural studies. This study aims to compare five RPs (ERA5, ERA5-Land, SCOPE Climate, FYRE Climate, and RFHR) at reproducing observed AgcIs over France. The RPs are evaluated against the SYNOP meteorological data over the 1996–2012 period, focusing on six AgcIs specific to apple, maize, and vine crops. The findings show that RPs perform well in reproducing temperature-based AgcIs, with some slight discrepancies in areas with complex topography. However, all RPs tend to overestimate precipitation amounts and to underestimate dry days, leading to a poor performance in reproducing precipitation-based AgcIs. This study emphasizes the need for a thorough evaluation of the RPs in developing both temperature-based and precipitation-based AgcIs, especially if findings are intended to support operational agricultural decision-making.

Most collective agroecological initiatives in Europe today are built around a plurality of knowledge systems. Going beyond the well-documented instrumental goals of this knowledge-plurality, this paper highlights another, perhaps less obvious objective: the pursuit of recognition and cognitive justice. The subordination of alternative farming practices, such as agroecology, to industrial high-input farming leads to the misrecognition of peasant communities. Challenging industrial agriculture hence requires both equality between different forms of doing farming and an active engagement with different ways of knowing farming. Cognitive justice, a concept originating in decolonial thought, encompasses not only the right of different practices to co-exist, but entails an active engagement across their knowledge-systems. Using an example of participatory maize breeding in France, the paper illustrates how peasant movements in Europe organize an ’agroecology of knowledges’, a counter-hegemonic engagement with modern agronomic science, through the recovery and co-production of situational, environment-specific knowledge, and the reskilling of farmers. It aims not only at improving agricultural science, but also at rebuilding collective identities and reclaiming autonomy. [ABSTRACT FROM AUTHOR]

Predicting wheat growth stages using ecophysiological models is of particular interest as it allows anticipating important agricultural managements. Numerous ecophysiological models exist but they need cultivar-specific parameterization, which is often costly and time consuming. The work presented here proposes a simple approach to predict wheat growth stages using the allelic composition of wheat cultivars. It relies on using the prediction of a modified version of the ARCWHEAT model for a well parameterized reference cultivar (Soissons) and the marker-based predicted deviation in days to the reference cultivar. First, the deviations to the reference cultivar Soissons for the beginning of stem elongation (δZ30) and heading date (δZ55) were calculated for a large panel of cultivars. Analysis of variance showed prominent genetic effects for δZ30 and δZ55 and possible genotype × environment interactions ( G × E ) for δZ30. Genotypic means δZ30 and δZ55 were used in association genetics revealing 90 and 83 genetic markers associated to these traits, respectively. Multiple linear regression models predicting δZ30 using 11 genetic markers ( R 2 = 76%) or δZ55 using 17 markers ( R 2 = 85%) were obtained by a stepwise procedure. Marker PPD-D1 had the largest impact in both models. Finally, marker-based deviations added to the prediction for the reference cultivar Soissons allowed predicting Z30 or Z55 for a large independent validation dataset. The root mean square error of prediction for Z30 and Z55 using the approach proposed in this paper (6.8 and 4.7 days, respectively) was comparable to the one obtained using the conventional approach with cultivar-specific parameters values (6.5 and 4.1, respectively). The models proposed in this paper appeared sufficient in order to predict growth stages of cultivars which cannot be parameterized such as new cultivars coming out on the market. Moreover, genetic markers involved in the multiple linear regression models predicting δZ30 and δZ55 may provide interesting candidates to unravel new genes determining earliness in winter wheat.

Extreme weather events have strong impacts on agriculture and crop insurance. In France, drought (2003, 2011, 2017, and 2018) and excess of water (2016) are considered the most significant events in terms of economic losses. The crop (re)insurance industry must estimate its financial exposure to climatic events in terms of the average annual losses and potential extreme damages. Therefore, the objective of this paper was to develop a model that links meteorological indices to crop yield losses with a specific focus on extreme climatic events. We designed a meteorological index (DOWKI: Drought and Overwhelmed Water Key Indicator) based on a water balance cumulative anomaly that can explain drought and excess of water at the department scale. We propose a crop damage model calibrated by combining historical yield records and the DOWKI values. To estimate the financial exposure of insured crops at a national level, stochastic simulations of the DOWKI were performed to produce one thousand years of yield losses. Our objective was to estimate the effect of climatic extremes affecting the global production. Simulated average annual losses and the possible maximum claim for three crops (soft winter wheat, winter barley, and sunflower) are presented in the results. [ABSTRACT FROM AUTHOR]

In the recent years agriculture as a branch of economy has been the subject of large transformations. Agricultural holdings have played a very important role for the sustainable socio-economic development. Agriculture is becoming more modern but its contribution to GDP is decreasing. The question as to the connection between the condition of the agricultural market and economy-wide conditions and sustainable development seems to be fundamental. This is the objective of this paper. Based on wheat prices and in the US, the UK, France and Poland in the years 2000-2018, the connection between these variables was determined. The tests for causality were carried, and the auto-regression VAR model was built. The general conclusions are consistent. It is evident that economy-wide conditions indeed depend on the prices of agricultural produce from the previous periods. High prices for agricultural produce and, in particular those of wheat, weaken future economic conditions. This conclusion for Poland and France is strong, while it is weaker for the UK and the US.

Brownfields are a widespread problem in the world. The poor quality of these soils and the potential presence of contaminants can pose a significant threat to plant establishment and growth. However, it may be possible to improve their establishment with an appropriate agricultural practice. In this paper, the effects of two common planting strategies, seeding and transplanting, on the establishment and growth of the hyperaccumulator species Noccaea caerulescens and on its phytoextraction capacity were investigated. A field experiment was conducted by direct sowing of N. caerulescens seeds on a plot of contaminated Technosols in Jeandelaincourt, France. At the same time, seeds were sown on potting soil under controlled conditions. One month later, the seedlings were transplanted to the field. One year later, the results showed that transplanting improved the establishment and growth of N. caerulescens. This was due to a decrease in soil pH in the rhizosphere, which subsequently increased nutrient availability. This change in rhizosphere properties also appeared to be the key that improved microbial activities in the rhizosphere soil of transplanted plants. The observed improvement in both rhizosphere nutrient availability and microbial activities, in turn, increased auxin concentrations in the rhizosphere and consequently a more developed root system was observed in the transplanted plants. Furthermore, the Cd and Zn phytoextraction yield of transplanted plants is 2.5 and 5 times higher, respectively, than that of sown plants. In conclusion, N. caerulescens transplantation on contaminated sites seems to be an adequate strategy to improve plant growth and enhance trace metal phytoextraction. [Display omitted] • Transplanting improved metal phytoextraction on low-fertility Technosol. • Transplanted plants had a more developed root system due to higher root exudates. • High rhizosphere fertility of transplanted plants promoted microbial activities. • Cd and Zn extraction yield was much higher in transplanted N. caerulescens. • Transplanting could be an adequate strategy for contaminated site management.

Abstract This paper explores the relationship between past climate and prehistoric Mediterranean agriculture by adapting a process-based dynamic vegetation model to estimate potential agricultural productivity under climate scenarios that characterize the extremes of Mediterranean climate in the Holocene. We adapt LPJmL (the Lund-Potsdam-Jena-managed-land model [Bondeau et al., 2007]), a process-based dynamic vegetation model, to the modeling of potential agricultural productivity in the past. Calibrating this model for past crops and agricultural practices and using a downscaling approach to produce high spatiotemporal resolution paleoclimate data, we produce quantitative estimates of potential yields under past climatic conditions derived from four Holocene climatic extremes (warm/wet, warm/dry, cold/wet, and cold/dry) under two different assumptions (approximate high and low limits) about the intensity of agricultural practice. We here discuss this process with reference to a case study in Provence, examining the methodology and data requirements for modeling past agriculture using LPJmL and considering the implications of the range of variability in potential agricultural productivity under distinct climate conditions. We focus particularly on comparing the range of variability induced by climatic shifts with that achievable through changes in agricultural practices as a means of approaching questions of past vulnerability and resilience.

Agricultural research is expected to foster agro-ecological transitions. For that purpose, methodologies of participative integrated assessment of new farming and cropping systems are requested. However, the territory level and the stakeholders' participation are often not sufficiently embraced. Based on the companion modeling approach, a group of researchers from different disciplines experimented an approach where researchers and stakeholders collaborated intensively all along the process of design and use of the model. The researchers selected a small rural area where agriculture plays a major role (Valensole plateau, south of France) and where they had not carried out any investigation before. In such conditions, we argue that the interactions between researchers and stakeholders involved in the co-design from scratch of a simulation model stimulate a collective reflection about the sustainability of current and alternative farming systems. This article describes the different phases of the process from stakeholders' enrolment until the final discussion of the results provided by the model. It underlines the conditions that favored the emergence of consensus and the production of a new set of knowledge. It emphasizes how the discordances between data and disagreements between stakeholders were used to stimulate collective debates and underlines the role played by the model. Finally, the article discusses the drawbacks that the approach did not overcome. [ABSTRACT FROM AUTHOR]

Context There is a lack of data on pesticide exposure levels during spraying with a knapsack, while it could have important implications for their users' health. Methods We assessed levels and determinants of exposure in 24 male private landscapers/gardeners and municipal workers in France in 2011. Actual dermal exposure to glyphosate was assessed with cotton undergarments and gloves, and a cotton coverall changed between mixing and spraying to assess the contribution of each phase and body area to overall contamination. A field monitor observed the whole workshift and filled in a standardized observation grid. Results The median actual contamination was 5,256 µg for the body, and 4,620 µg for hands. Spraying was more exposing than mixing/loading for all body parts except hands, which contributed to nearly 90% of body exposure during mixing/loading, and 30% during spraying, followed by back (14%). In the most exposed quartile, levels were close to some observations in agriculture. Conclusion Our study provides new data on pesticide exposure levels of knapsack sprayer users; it should lead to a reinforced prevention, in order to make exposures as low as possible and lessen the risk of chronic diseases.

New models of collective agriculture have been developing in France over the past 10 years that could encourage the emergence of more diversified and sustainable systems. However, as such production systems are relatively more complex to manage, the involvement of more people may be required. This raises renewed questions concerning the collective organization of work. Our study's main hypothesis is that the collective organization of work could encourage crop-livestock integration and underlying agroecological processes. To test this hypothesis, we implemented a participatory design approach in a case study in Camargue (France). We first used ecological network analysis to characterize flows of material between production units and assess associated biotechnical performances, namely, efficiency, resilience, productivity, and dependence. In a second step, we drew from the QuaeWork method, which we adapted to the study of collective farms, to characterize the organizational dimension. These two methods allowed us to generate quantitative indicators related to the performance of the system (expressed in kgN.ha−1.yr−1) and to calculate and estimate the time spent on various types of work (h.yr−1). Using a participatory design approach, we then developed and assessed three scenarios with varying levels of integration between activities. The results indicate that the gradual substitution of external resources by internal resources leads to a broader range of flows within the system, generating performances that vary depending on the scenario. The design of the scenarios revealed the repercussions of the organization of work within production units. The two most integrated scenarios are more efficient and resilient than the scenario without integration between units, but they are less productive. Our research contributes novel insights into the impact of agroecological practices on the organization of work on collective farms. Our findings enable a deeper understanding of the complex link between the collective organization of production and the articulation of activities. [ABSTRACT FROM AUTHOR]

Market sociology research has accounted amply for the importance of material devices in shaping markets. In contrast, the influence of biological entities (such as parasites, soil, and food) on market agencing has barely been considered. This article shows the relevance of covering this matter specifically. To do so, the authors refer to their analyses of the production and sales practices of organic vegetable market actors in France. Based on descriptions of four situations, they show that the biological processes involved in the cultivated ecosystems and agricultural produce itself influence the market agencing processes that these actors carry out. Based on these first observations, they propose four generic statements that clarify what considering the action of biological entities involves in terms of theory and identify avenues for future research.

An introduction is presented in which the editors discuss various reports published within the issue on topics including the underlying structures of the famine in Nordic history, the grain trade from the Baltic provinces to Finland and Sweden during the 1690s, and a long-term view on trade and agriculture in Northern France from 5400 BC to 3900 BC.

Interaction between mitigation and adaptation is a key question for the design of climate policies. In this paper, we study how land use adaptation to climate change impacts land use competition in the agriculture, forest and other land use (AFOLU) sector and how a mitigation policy in agriculture might affect this competition. We use for this purpose two sector-specific bio-economic models of agriculture and forest combined with an econometric land use shares model to simulate the impacts of two climate change scenarios (A2 and B1, 2100 horizon), and a greenhouse gas emissions from agriculture policy consisting of a tax of between 0 and 200 €/tCO 2 equivalent. Our results show that both climate change scenarios lead to an increase in the area devoted to agriculture at the expense of forest which could have a negative impact on reducing greenhouse gas emissions responsible for climate change. The mitigation policy would curtail agricultural expansion, and thus could counteract the effects of land use adaptation to climate change. In other words, accounting for land use competition results in a reduction of the abatement costs of the mitigation policy in the agricultural sector. [ABSTRACT FROM AUTHOR]

The paper focuses on the importance of social capital as a significant cause of territorial innovation in French agriculture. Social capital, as a relational resource, is embedded in a social network of innovation which is created by different agricultural professions also known as rural professional identities. A social network of innovation is related in our case to the agricultural professions and differentiated according to their capacity of changing more the interaction capital rather than the technological assets of everyone. More than the social relationship itself between individuals and the resources carried on by everyone, we emphasize the importance of their integration in a social network. Thus, two types of agricultural professions profiles are highlighted (Ceapraz and Delhoume, 2014) and related to territorial innovation. [ABSTRACT FROM AUTHOR]

In this paper, we present our Semantic Web system for the storage of 19,448 agricultural alert bulletins in France. The archive of alert bulletins was published on the Web as Linked Open Data (LOD). LOD uses Semantic Web technologies to publish data on the Web. Some best practices for publishing Linked Data are already proposed. We enrich these best practices in order to meet some specific information retrieval needs: spatiotemporal and thematic annotations and aggregation indicators. We illustrate our proposal by the publication of our archive. We describe our methodology for building the system and highlight the interest regarding Semantic Web technologies for this agricultural alert storage, publication and analysis. To prove that our system answers our needs, we propose some queries to illustrate the calculation of spatiotemporal aggregation indicators. [ABSTRACT FROM AUTHOR]

Having long been confined to the role of family farm helper, women now make up more than a quarter of farm managers in France. Alongside that, the agricultural world needs to transition towards more sustainable practices and models. Inadequate or incomplete research can be found on how gender influences farmers' practices and even fewer studies that focus on the situation in France. In this paper, the relationship between the specific topic of French women farmers and their role in sustainable agriculture is explored through qualitative research. An initial conclusion is reached on the existence of a gender effect in the practice of sustainable agriculture. Four explanations to this correlation are discussed to explain the dynamics between gender and sustainable agriculture: the importance of care and differentiated socialisation in choices that women make, the role of access to the profession and working conditions, the specific profile of women involved in sustainable systems and the potentially more welcoming dimension of the agroecological space. Although analysed separately, it is likely a combination of these explanations that allows us to understand the greater sensitivity of women to engage in sustainable agricultural practices. • Gender dynamics exist in the development of sustainable agriculture in France. • Education and socialisation are a strong lead to explain the sensitivity of women to engage in sustainable initiatives. • The influence of the more welcoming dimension of the agro-ecological space on this dynamic requires further analysis. • Women farmers engaged in sustainable projects have similar profiles and specific social characteristics.

Background: Agrivoltaism is presented as an innovative production system that may combine agricultural activity and energy production on the same parcel of land. The deployment of this innovation has already begun in France as part of the energy transition initiatives, and many actors consider that its deployment only depends on social acceptance issues. However, given that agrivoltaism cuts across the agricultural and energy sectors, social, technical, and political concerns have arisen. While these concerns are primarily reflected in conflict and opposition, the problem goes far beyond the simple question of social acceptance. Indeed, it relates to the dynamics of innovation and governance, structured in different arenas at different scales that shape how this innovation is deployed. Methods: The authors conducted a qualitative study revolving around three methodological approaches: a press analysis, a review of scientific literature, and fieldwork in the Pyrénées-Atlantiques district in France. Drawing on the case of a disputed project, several semi-structured interviews were conducted. These interviews explored how the public sector, institutions, energy companies, and local farmers perceive the development of agrivoltaics and how they organise the dynamics of governance to control its deployment. Results: Our analysis highlights four main results: (i) agrivoltaism is an innovation conceptualised in techno-scientific arenas which seek to define its agricultural viability; (ii) at the national level, the remote control by the State does not provide a framework for governance capable of involving the various actors in the fields of agriculture and energy; (iii) the deployment of agrivoltaism systems across regions engenders conflict while placing key local actors in a situation of uncertainty with regard to how best to manage this innovation; (iv) while individuals are subjected to territorialisation, this paradoxically favours structural policy innovations which outline the contours of territorial governance. Conclusions: This study shows that agrivoltaism is the result of interactions between techno-scientific actors in the energy and agricultural fields. However, its political backing in France does not promote dynamics of governance capable of bringing these two fields together. At the local level, the deployment of agrivoltaism has faced opposition, but it has also led to the organisation of territorial governance strategies involving actors and institutions from different sectors.

Background: Proven toxicity and environmental burdens caused by artificial dyes have motivated dyeing industries to turn to natural alternatives. Plant-based dyestuffs are an interesting group of alternative crops. Reunion Island located in the Indian Ocean is the only European region in the southern hemisphere. It has a great number of assets to find new molecules in the abundant plant biodiversity. However, the dye-producing plants diversity in this island had not been documented to date. Methodology: The assessment of the Reunion Island's plant biodiversity through the "PLANTIN" project allowed us to establish here the first ethnobotanical inventory of plants growing on Reunion Island which may have promising properties as a new alternative source of dyes or colorants for the industries. First, an ethnobotanical survey focused on the uses of plants traditionally used in dyeing was conducted on local stakeholders. Then, the importance of different criteria (e.g., endemicity, accessibility and cultivability, plant organs used for the extraction, industrial interests of the species, etc.) has been considered to establish a classification method of the species, to finally select the most interesting plants which have been further harvested and investigated for their coloring property and dyeing application on natural fibers. Results: The results showed that local people have accumulated traditional knowledge of dyeing plants, but that this approach had been discontinued in Reunion. The uses of 194 plant species potentially rich in dyes or pigments, belonging to 72 different families, with diverse botanical status (endemic, native, introduced or alien-invasive species) have been recorded. Then, 43 species were harvested and their coloring property were investigated. It demonstrated that dyes extracted from promising species, e.g., Terminalia bentzoe, Weinmannia tinctoria, Thespesia populnea, Erythroxylum laurifolium, Morinda citrifolia, Leea guinensis, Ochrosia borbonica, Danais fragrans, Terminalia cattapa, Casuarina equisetifolia, and Coccoloba uvifera, amongst others, could be used as new textile dyes. Their efficacy in the wool and cotton dyeing has been successfully demonstrated here. Conclusion: These plant-based dyestuffs showed promising coloring properties with different shades that could meet industrial application requirement. It's an area that could promote local cultural inheritance, create opportunity for business and farmers, and that can make a significant contribution to preserving endangered native species by supporting reforestation schemes. Additional researches are in progress to evaluate the safety of these plant-based colored extracts, their chemical composition and biological activities. [ABSTRACT FROM AUTHOR]
