    Authors: Corniaux, Christian; Baritaux, Virginie; Madelrieux, Sophie;

    Dans un contexte de globalisation des échanges, les filières agricoles s’inscrivent désormais dans un double processus de mondialisation et de territorialisation des flux (produits agricoles, énergie, intrants, travail…). C’est particulièrement vrai pour la filière laitière où se côtoient les plus grands groupes agroalimentaires internationaux, tournés en priorité vers des produits de masse standardisés, et des petites unités de transformation qui s’inscrivent souvent dans des circuits plus courts avec des produits typés ou différenciés par leur origine géographique. L’objectif de cet article est de montrer qu’au-delà de représentations hâtives ou caricaturales, les stratégies spatiales des laiteries, indépendamment de leur forme économique et de leur taille, s’inscrivent dans ce double processus de globalisation et de (re)localisation à l’œuvre dans les territoires laitiers. Des travaux effectués dans six bassins laitiers à travers le monde (Vietnam, Uruguay, Sénégal et France : Vercors, Livradois-Forez et Cévennes) montrent que partout ces deux processus ne sont pas exclusifs mais opèrent ensemble dans un même territoire et au sein des laiteries, créant des tensions mais aussi des complémentarités. Ainsi, des formes hybrides entre « local » et « global » émergent pour durer et se développer dans les territoires laitiers. In a context of trade’s globalization, agricultural sectors are now part of a double process of globalization and territorialisation of the flux (energy, inputs, agricultural products, work...). This is particularly true for the dairy industry which combines the largest agri-food international groups, turned on a priority basis to produce for standardized mass, and small processing units that are often shorter circuits with typical or differentiated by their geographical origin products. The objective of this article is to show that beyond hasty or caricatured representations, the spatial strategies of dairies, independently economic shape and size, are part of this double process of globalization and (re) location in the dairy territories. Studies done in six dairy basins around the world (Senegal, Uruguay, Viet Nam and France: Vercors, Livradois - Forez and Cévennes) show that throughout these two processes are not exclusive but operate together within the same territory and dairies, creating tensions but also complementarities. Thus, hybrid forms between 'local' and 'global' emerge and spread in the milk territories.

    Review of the Sicilo-Sarda dairy sheep micro-sector in Tunisia: current situation and prospects for the recovery of the Sicilo-Sarda breed Introduction. The Sicilo-Sarda is the only Tunisian dairy sheep breed. Milk from this breed is used in a micro-sector of cheese production. Numbers of sheep from this breed fell significantly during the 1990s, due to unfavorable economic and political choices, as well as a lack of technical control of livestock, which risked the sustainability of this cheese production sector. However, initiatives to preserve this breed have taken place in recent years. The present review of the scientific and professional literature highlights the current knowledge of the sheep dairy sector in Tunisia and presents the actions currently under way or to be undertaken in favor of its safeguarding.Literature. The Sicilo-Sarda breed shows low levels of milk production but this can be improved even in extensive systems. Breeding (suckling/weaning/milking) and reproductive management needs to be reviewed in order to increase milk production. Similarly, the breed’s genetic pathway needs to be mobilized through the establishment of a selection scheme based on farm phenotypes of interest (quantity and quality of milk, mammary morphology) and/or the introduction of Sardinian blood via artificial insemination. Conclusions. A renewed interest in the Sicilo-Sarda breed in Tunisia has been noted since 2005 through a reorganization of the sector, giving new dynamism to the profession. Significant margins of progress have been highlighted, both in terms of animals and breeders. The downstream sector of this milk chain must also help create a better identification of the products and the “terroir” of production for consumers. This will create new opportunities to develop this micro-sector to ensure its sustainability. Introduction. La race sicilo-sarde est la seule race ovine laitière tunisienne. Elle est à la base d’une micro-filière de production de fromages. Son effectif s’est effondré dans les années 1990 en raison de choix économiques et politiques peu favorables ainsi que d’un manque de maitrise technique des élevages, mettant la pérennité de cette filière en danger. Toutefois, des initiatives pour la préserver sont entreprises depuis quelques années. Cette revue de la littérature, scientifique et professionnelle, fait le point sur les connaissances actuelles de la filière laitière ovine et présente les actions en cours ou à entreprendre en faveur de sa sauvegarde.Littérature. La race sicilo-sarde affiche des niveaux de production laitière faibles mais améliorables, même dans des conditions extensives. Les conduites d’élevage (allaitement/sevrage/traite) et de reproduction devraient être revues afin d’accroitre la production laitière. De même, la voie génétique devrait être mobilisée par la mise en place d’un schéma de sélection appuyé sur le relevé de phénotypes d’intérêt en ferme (quantité et qualité de lait, morphologie mammaire) et/ou par introduction de sang sarde en recourant à l’insémination artificielle. Conclusions. Un regain d’intérêt pour la race sicilo-sarde en Tunisie est constaté depuis 2005, à travers une réorganisation de la filière, insufflant un nouveau dynamisme au sein de la profession. Les marges importantes de progrès ont été mises en évidence, tant au niveau des animaux que des éleveurs. L’aval de la filière doit aussi aider à une meilleure identification des produits et du terroir de production auprès des consommateurs. Ainsi se dessineront de nouvelles opportunités de développement de cette micro-filière, seule à même d’assurer sa durabilité.

    article présenté lors du colloque "Associations Végétales" Angers 20 novembre 2014; This paper deals with annual cereal-legume intercrops harvested for grain production for animal or human consumption or for the production of silage or hay when whole plants are harvested. It presents feedbacks from farmers who already practiced these intercrops. Expected and observed benefits and limitations of these systems perceived by farmers are discussed in the light of results of research. Many benefits of intercrops are mentioned, especially compared to sole legumes that are difficult to manage, particularly in organic farming: reduction of pests and lodging, overall higher yields (and higher stability), increase in nitrogen concentration of the harvested products, reduction of nitrogen fertilization, etc. However, limitations remain to be overcome, concerning the management of intercrops (sowing, fertilization, harvest), proportions of each species at harvest, and market, especially in the case of grain production (collection, sorting, outlet).; Cet article traite des associations annuelles céréale-légumineuse récoltées pour la production de grains destinés à l’alimentation animale ou humaine, ou pour la production d’ensilage ou de foin lorsque les espèces sont récoltées en plante entière. Il présente des retours d’expériences d’agriculteurs ayant pratiqué ces associations, en distinguant les bénéfices attendus ou observés, et les limites de ces systèmes. Ces bénéfices et limites sont discutés au regard de résultats issus de la recherche. De nombreux bénéfices des associations sont mentionnés, en particulier par rapport aux légumineuses pures dont la conduite est difficile, surtout en agriculture biologique : réduction des bioagresseurs et de la verse, gain de rendement global (et de stabilité), enrichissement en azote des produits récoltés, réduction de l’utilisation de la fertilisation azotée à l’échelle des successions, etc. Des limites restent cependant à lever, qui concernent la conduite des associations (semis, fertilisation, récolte), la maîtrise des proportions à la récolte, et la valorisation, particulièrement dans le cas de la production de grains (collecte, tri, débouché).

    La spectrométrie dans le proche infrarouge (SPIR) est une technique analytique qui a connu un développement important dans le domaine de l’alimentation animale. Rapide et peu coûteuse, elle trouve sa place dans un contexte de besoin croissant de contrôle qualité et de traçabilité. La première utilisation de la SPIR est l’analyse des matières premières, depuis leur production (organismes stockeurs) jusqu’à la réception des lots chez les fabricants d’aliment. La SPIR permet de mesurer la composition chimique (humidité, protéines, lipides, etc.) mais également d’estimer la valeur nutritive (digestibilité des acides aminés, énergie métabolisable) et se révèle donc un outil précieux pour la formulation. Au cours de la fabrication comme sur les produits finis, la SPIR permet aussi d’analyser les aliments composés et de vérifier leur conformité aux formules théoriques. Les nouveaux matériels permettent de mettre en place des mesures directement « en ligne » lors de la production. L’utilisation de la SPIR peut dépasser l’usine, et des résultats récents montrent que des perspectives intéressantes se dessinent pour des mesures de digestibilité beaucoup plus proches du terrain que les expérimentations classiques. Enfin la caractérisation des effluents permet à la fois de mieux orienter leur utilisation et se servir de l’information (humidité, azote) comme aide au diagnostic de problèmes d’élevage. Near infrared spectroscopy (NIRS) is an analytical technique which has undergone a very important development in the field of animal feeds. Rapid and cheap, it is particularly valuable in a context of increasing need for quality control and traceability. The main use of NIRS is the raw material analysis, from their production (traders / storage facilities) down to the purchase of batches by the feed manufacturers. NIRS allows measuring chemical composition (moisture, protein, lipids, etc.) but also nutritional value (amino acid digestibility, metabolizable energy …) and is therefore a valuable tool for feed formulation. During feed processing as well as on finished products, NIRS is also used to analyze compound feeds and to check their conformity with expected formula. New equipment also allow the settlement of “on line” measurements during production. The use of NIRS can go beyond the feed factory, and recent results show interesting perspectives for digestibility measurements closer from real field conditions than classical experiments. At last, the characterization of effluents is a means to optimize their use, and to value the information (moisture, nitrogen) as a tool for diagnostic of rearing problems.

    Authors: Gusmawati, Niken Financia;

    La production de crevettes en Indonésie est en constante augmentation de part sa surface et l'intensification de ses élevages. Cette filière contribue au développement économique en milieu rural, à la sécurité alimentaire nationale, à l'emploi et au commerce extérieur. Cependant, ce développement rapide s'est accompagné d'effets écologiques et sociaux négatifs. Le développement de maladies dans les élevages ainsi que la dégradation de l'environnement côtier a conduit à l'abandon de 250 000 hectares de bassins dans le pays. Leur réhabilitation dans le cadre d'une activité durable est aujourd'hui une priorité pour le gouvernement indonésien.L'objectif de cette thèse est de développer des outils et des méthodes, basées sur de l’imagerie satellites à très haute résolution spatiale (THRS), (1) pour une meilleure gestion des sites de production et (2) pour réhabiliter les sites abandonnés. L'estuaire de la Perancak situé dans la Province de Bali, une zone de production en déclin, a été choisi comme site pilote. Ce travail a été réalisé dans le cadre du projet INDESO dont l'objectif était de fournir des outils et des méthodes pour une meilleure gestion des ressources côtières et marines en Indonésie.Le premier outil développé pour objectif de cartographier automatiquement les bassins d'élevage. A cet effet, une méthode basée sur la détection des contours a été mise en place et comparée à deux autres méthodes, la première basée sur la méthode de croissance des régions, la seconde sur une classification non supervisée (plus particulièrement la méthode Isocluster). Notre méthode a permis de détecter une forte proportion de bassins avec une meilleure précision.Le second outil avait pour objectif de distinguer les bassins actifs des bassins abandonnés. Un indicateur intégré (IPAI) basé sur quatre critères identifiés sur les images THRS que sont la présence d'eau, d'aérateur(s), de ponton(s) d'alimentation et de végétation, a été développé. Cet indicateur permet de distinguer significativement un bassin actif d'un bassin inactif. La présence de ponton est le critère qui s'est révélé être le plus discriminant.Cet indicateur a été utilisé sur l'estuaire de la Perancak pour suivre la dynamique d’abandon des bassins, liée au développement des maladies dans les élevages, entre 2001 et 2015. Deux facteurs de risque conduisant à l'abandon ont été mis en évidence : le climat et le positionnement des bassins au sein de l'estuaire. Ces résultats suggèrent qu'une approche spatiale doit être prise en compte pour la réhabilitation des bassins. Trois zones ont été définies à partir de leur résilience spatiale aux maladies. Le niveau de connectivité entre des bassins via le réseau hydrologique augmente le risque d'abandon. A noter que la présence actuelle des pathogènes (White Spot Syndrome Virus, WSSV) dans les bassins et probablement dans l'environnement génère une mémoire écologique défavorable à la réhabilitation de fermes aquacoles de crevettes.A partir de ces résultats, une première proposition de plan pour réhabiliter les bassins abandonnés a été formulée dans le cadre d'une approche écosystémique. Pour lutter contre les maladies, ce plan suggère de développer une aquaculture multi-trophique intégrée (AMTI), basée sur la diversité des espèces élevées et de leur positionnement dans la chaine trophique, à l'échelle de l'estuaire. Les méthodes et les études qui doivent être conduites pour rendre opérationnelle cette proposition sont discutées. Shrimp farming production in Indonesia has continuously increased through a large expansion of cultured areas and stocking density intensification. This activity supports rural economic development and contributes to national food security, employment and foreign exchange earnings. However, this development has generated adverse ecological and social effects. As consequences of diseases and environmental degradations, there are currently 250,000 ha of abandoned ponds. Their rehabilitation, within a sustainable aquaculture framework, is actually a high priority for the Indonesian government.The objective of the present PhD work was to develop tools and methodologies to (1) enable better management for operating sites of shrimp industry and (2) rehabilitate abandoned sites using very high-resolution satellite (VHRS) imagery. The Perancak Estuary, located in Bali Province, is the production area in decline that has been chosen as study site. This work has been carried out in the frame of the INDESO project which was assigned to develop and provide tools and methods for better management of marine and coastal resources in Indonesia.The first developed tool was an automatic classification procedure for aquaculture mapping. A method based on Edge Detection on VHRS images was proposed and compared with those generated by Region Growing segmentation and unsupervised classification Isocluster. Edge Detection method could successfully create aquaculture map in the Perancak estuary by identifying a large proportion of existing ponds, with good overall accuracy.To implement effective procedure for appropriate aquaculture ecosystem assessment and monitoring, the second tool was an Integrated Pond Activity Indicator (IPAI). It aimed to discriminate active from abandoned ponds and was developed based on four criteria using VHRS images. Those criteria were: presence of water, aerator, feeding bridge and vegetation. This indicator succeeded in detecting active pond with a good accuracy, and feeding bridge appeared to be the most discriminant criteria.This second indicator has then been applied to the Perancak estuary to highlight the abandonment dynamic due to disease between 2001 and 2015. Two risk factors that could contribute to explain dynamics of abandonment were identified: climate conditions and pond locations within the estuary, suggesting that a spatial approach should be integrated in planning processes to operationalize pond rehabilitation. Three areas were defined based on their disease resilience. Ponds connectivity through water network increased the risk of disease development. The continued presence of shrimp pathogen species in ponds and probably in the environment (i.e. White Spot Syndrome Virus, WSSV) may generate ‘ecological memories’ that prevent to the return of shrimp productive system.These results were used to establish a first proposal of rehabilitation plan using an ecological approach. At the whole ecosystem scale, the development of an integrated multi-trophic aquaculture (IMTA), based on the diversity of cultured species and their trophic status would be implemented. Methods and studies that would be conducted to operationalize sustainable pond rehabilitation are briefly discussed.

    Authors: Houdart, Marie, M.; Baritaux, Virginie; Cournut, Sylvie;

    Le Livradois-Forez est un territoire de moyenne montagne, situé au centre de la France, marqué par la production de différents fromages emblématiques comme les appellations d’origine protégées Fourme d’Ambert et Bleu d’Auvergne. Depuis les années 1990, on assiste à un réancrage territorial de la production laitière qui succède à un mouvement lent de désancrage. Ces mouvements sont souvent associés à l’influence exercée par les acteurs de l’aval de la production agricole (transformateurs, distributeurs, consommateurs). Nous avons donc cherché à éclairer la façon dont, dans ce bassin laitier du Livradois-Forez, les stratégies et la structuration des acteurs de l’aval de la filière, et en particulier les acteurs de la première transformation, ont influencé la dynamique de désancrage/réancrage de la production laitière. Pour cela, nous avons effectué une lecture croisée des évolutions relatives au territoire, aux systèmes d’élevage et à la filière, sur le temps long. Cette analyse nous a permis de mettre en avant cinq séquences temporelles, marquées par des formes particulières d’interaction entre élevage, territoire et filière. La période antérieure à 1960 se caractérise par une production laitière ancrée dans le territoire. Entre 1960 et 1980 s’opère un mouvement lent de désancrage de la production laitière malgré l’émergence d’une identité territoriale forte. La décennie suivante confirme ce désancrage. Entre 1990 et 2000, plusieurs éléments participent à une amorce de réancrage de la production laitière, qui semble s’affirmer depuis 2000 malgré la concentration des exploitations et des laiteries. Tout au long de cette trajectoire, les stratégies commerciales des opérateurs de l’aval répondant aux évolutions des marchés (concurrence accrue, évolution des demandes des consommateurs…), les stratégies « industrielles » (optimisation de la collecte, nécessité d’un approvisionnement local…) et les restructurations du tissu industriel (disparitions, rachats, fusions…) jouent sur l’ancrage de la production laitière, en termes tant de produits que de localisation des activités de la production. Livradois-Forez is a middle mountain region located in the Central France. Several Cheese Protected Designations of Origin, as Fourme d’Ambert and Bleu d’Auvergne, are produced in this region. After a slow trend towards disembeddedness, since the nineties, milk production has tended towards local re-embeddedness. These trends may be associated to the influence of the downstream stakeholders of the value chain (processors, retailers and consumers). We aim at highlighting how, in Livradois-Forez, these stakeholders’ strategies and organization determine this dynamic of milk production dis-embeddedness/re-embeddedness. Using a historical approach, we analyzed at the same time the evolutions of the territory, the livestock farming systems and the value-chain. We highlight five time sequences characterized by specific interactions between these three dimensions. Before 1960, the milk production was locally embedded ; between the 60’s and the 80’s, there was a slow movement of des-embeddedness ; the next decade confirmed this des-embeddedness ; in the 90’s, the reembeddedness began and then gained prominence starting from year 2000, in spite of the concentration of farms and dairies. Throughout this trajectory, a combination of elements influences the embeddedness of milk production: commercial strategies of downstream stakeholders linked with the evolution of world markets (increasing competition, changes in the consumers’ expectations); ‘industrial’ strategies (optimization of milk collection, need of local supply); restructuration of industrial fabrics (disappearances, takeovers, mergers).

    Authors: Corniaux, Christian; Baritaux, Virginie; Madelrieux, Sophie;

    Dans un contexte de globalisation des échanges, les filières agricoles s’inscrivent désormais dans un double processus de mondialisation et de territorialisation des flux (produits agricoles, énergie, intrants, travail…). C’est particulièrement vrai pour la filière laitière où se côtoient les plus grands groupes agroalimentaires internationaux, tournés en priorité vers des produits de masse standardisés, et des petites unités de transformation qui s’inscrivent souvent dans des circuits plus courts avec des produits typés ou différenciés par leur origine géographique. L’objectif de cet article est de montrer qu’au-delà de représentations hâtives ou caricaturales, les stratégies spatiales des laiteries, indépendamment de leur forme économique et de leur taille, s’inscrivent dans ce double processus de globalisation et de (re)localisation à l’œuvre dans les territoires laitiers. Des travaux effectués dans six bassins laitiers à travers le monde (Vietnam, Uruguay, Sénégal et France : Vercors, Livradois-Forez et Cévennes) montrent que partout ces deux processus ne sont pas exclusifs mais opèrent ensemble dans un même territoire et au sein des laiteries, créant des tensions mais aussi des complémentarités. Ainsi, des formes hybrides entre « local » et « global » émergent pour durer et se développer dans les territoires laitiers. In a context of trade’s globalization, agricultural sectors are now part of a double process of globalization and territorialisation of the flux (energy, inputs, agricultural products, work...). This is particularly true for the dairy industry which combines the largest agri-food international groups, turned on a priority basis to produce for standardized mass, and small processing units that are often shorter circuits with typical or differentiated by their geographical origin products. The objective of this article is to show that beyond hasty or caricatured representations, the spatial strategies of dairies, independently economic shape and size, are part of this double process of globalization and (re) location in the dairy territories. Studies done in six dairy basins around the world (Senegal, Uruguay, Viet Nam and France: Vercors, Livradois - Forez and Cévennes) show that throughout these two processes are not exclusive but operate together within the same territory and dairies, creating tensions but also complementarities. Thus, hybrid forms between 'local' and 'global' emerge and spread in the milk territories.

    National audience; Le projet Telesphore s'inscrit dans le programme RISMEAU : une collaboration entre les partenaires territoriaux (SM3A, SRB, Chambre d'Agriculture Savoie Mont Blanc), des professionnels de la santé et du monde agricole, des scientifiques. Il rassemble des compétences complémentaires pour apporter une vision globale sur un territoire du périmètre du SAGE de l'Arve. L'objectif est de caractériser, de comparer les intrants urbains (issus des stations d'épuration) et agricoles (issus de l'élevage) et d'évaluer la contamination possible par les produits pharmaceutiques et les biocides des sols et des eaux souterraines due à l'épandage de boues et de lisiers comme fertilisants. Le programme RISMEAU comporte également le projet Perséphone, qui vise à évaluer les impacts environnementaux (écotoxicologie, antibiorésistance).

    Review of the Sicilo-Sarda dairy sheep micro-sector in Tunisia: current situation and prospects for the recovery of the Sicilo-Sarda breed Introduction. The Sicilo-Sarda is the only Tunisian dairy sheep breed. Milk from this breed is used in a micro-sector of cheese production. Numbers of sheep from this breed fell significantly during the 1990s, due to unfavorable economic and political choices, as well as a lack of technical control of livestock, which risked the sustainability of this cheese production sector. However, initiatives to preserve this breed have taken place in recent years. The present review of the scientific and professional literature highlights the current knowledge of the sheep dairy sector in Tunisia and presents the actions currently under way or to be undertaken in favor of its safeguarding.Literature. The Sicilo-Sarda breed shows low levels of milk production but this can be improved even in extensive systems. Breeding (suckling/weaning/milking) and reproductive management needs to be reviewed in order to increase milk production. Similarly, the breed’s genetic pathway needs to be mobilized through the establishment of a selection scheme based on farm phenotypes of interest (quantity and quality of milk, mammary morphology) and/or the introduction of Sardinian blood via artificial insemination. Conclusions. A renewed interest in the Sicilo-Sarda breed in Tunisia has been noted since 2005 through a reorganization of the sector, giving new dynamism to the profession. Significant margins of progress have been highlighted, both in terms of animals and breeders. The downstream sector of this milk chain must also help create a better identification of the products and the “terroir” of production for consumers. This will create new opportunities to develop this micro-sector to ensure its sustainability. Introduction. La race sicilo-sarde est la seule race ovine laitière tunisienne. Elle est à la base d’une micro-filière de production de fromages. Son effectif s’est effondré dans les années 1990 en raison de choix économiques et politiques peu favorables ainsi que d’un manque de maitrise technique des élevages, mettant la pérennité de cette filière en danger. Toutefois, des initiatives pour la préserver sont entreprises depuis quelques années. Cette revue de la littérature, scientifique et professionnelle, fait le point sur les connaissances actuelles de la filière laitière ovine et présente les actions en cours ou à entreprendre en faveur de sa sauvegarde.Littérature. La race sicilo-sarde affiche des niveaux de production laitière faibles mais améliorables, même dans des conditions extensives. Les conduites d’élevage (allaitement/sevrage/traite) et de reproduction devraient être revues afin d’accroitre la production laitière. De même, la voie génétique devrait être mobilisée par la mise en place d’un schéma de sélection appuyé sur le relevé de phénotypes d’intérêt en ferme (quantité et qualité de lait, morphologie mammaire) et/ou par introduction de sang sarde en recourant à l’insémination artificielle. Conclusions. Un regain d’intérêt pour la race sicilo-sarde en Tunisie est constaté depuis 2005, à travers une réorganisation de la filière, insufflant un nouveau dynamisme au sein de la profession. Les marges importantes de progrès ont été mises en évidence, tant au niveau des animaux que des éleveurs. L’aval de la filière doit aussi aider à une meilleure identification des produits et du terroir de production auprès des consommateurs. Ainsi se dessineront de nouvelles opportunités de développement de cette micro-filière, seule à même d’assurer sa durabilité.

    article présenté lors du colloque "Associations Végétales" Angers 20 novembre 2014; This paper deals with annual cereal-legume intercrops harvested for grain production for animal or human consumption or for the production of silage or hay when whole plants are harvested. It presents feedbacks from farmers who already practiced these intercrops. Expected and observed benefits and limitations of these systems perceived by farmers are discussed in the light of results of research. Many benefits of intercrops are mentioned, especially compared to sole legumes that are difficult to manage, particularly in organic farming: reduction of pests and lodging, overall higher yields (and higher stability), increase in nitrogen concentration of the harvested products, reduction of nitrogen fertilization, etc. However, limitations remain to be overcome, concerning the management of intercrops (sowing, fertilization, harvest), proportions of each species at harvest, and market, especially in the case of grain production (collection, sorting, outlet).; Cet article traite des associations annuelles céréale-légumineuse récoltées pour la production de grains destinés à l’alimentation animale ou humaine, ou pour la production d’ensilage ou de foin lorsque les espèces sont récoltées en plante entière. Il présente des retours d’expériences d’agriculteurs ayant pratiqué ces associations, en distinguant les bénéfices attendus ou observés, et les limites de ces systèmes. Ces bénéfices et limites sont discutés au regard de résultats issus de la recherche. De nombreux bénéfices des associations sont mentionnés, en particulier par rapport aux légumineuses pures dont la conduite est difficile, surtout en agriculture biologique : réduction des bioagresseurs et de la verse, gain de rendement global (et de stabilité), enrichissement en azote des produits récoltés, réduction de l’utilisation de la fertilisation azotée à l’échelle des successions, etc. Des limites restent cependant à lever, qui concernent la conduite des associations (semis, fertilisation, récolte), la maîtrise des proportions à la récolte, et la valorisation, particulièrement dans le cas de la production de grains (collecte, tri, débouché).
