    Après l'exposé général traitant de certains aspects de l'amélioration génétique de l'ananas, objet de la première partie de ce document, le cas particulier des travaux menés en Côte d'Ivoire est ici plus précisément abordé. Les objectifs de sélection définis à partir du contexte local ivoirien, le choix des géniteurs utilisés pour la réalisation des hybridations et les techniques mises au point pour la création et le suivi des descendances sont exposés. L'efficacité des méthodes décrites est à base de la sélection qui sera opérée sur la population de grande variabilité induite. 10 photos. (Résumé d'auteur)

    Authors: Gouyon, Anne; Penot, Eric;

    Pendant près de 75 ans on a assisté avec l'hévéaculture à l'extension d'un système agroforestier à faible productivité, sans changement technique significatif. Depuis le début des années 1980, un nombre croissant de petits planteurs cherchent à modifier leurs systèmes de culture pour utiliser les variétés sélectionnées à haut potentiel de rendement, multipliées par greffages (clones) et proposées par les projets de développement. Les paysans ne sont pas tous en mesure de mobiliser les financements nécessaires, de maîtriser les nouvelles techniques et de supporter les risques liés à ces changements. Un programme d'expérimentations est en cours afin de mettre au point des techniques nouvelles qui, en utilisant les méthodes de l'agroforesterie, pourraient permettre au plus grand nombre de planteurs d'augmenter leur revenu, tout en préservant au moins partiellement le milieu forestier des régions concernées

    Une exploitation agricole moyenne se compose de 6 personnes (3 actifs), cultive 2,2 ha, possède 1 bovin, 4 petits ruminants, 0,4 bovin de trait et 0,45 charrue. Les rendements sont relativement faibles: 950 kg/ha de coton, 2 100 kg/ha de maïs, 850 kg/ha de sorgho et 1 800 kg/ha d'arachide coque. La fumure minérale est utilisée surtout sur coton (110 kg/ha de NPK, et 25 kg/ha d'urée) et mais (90 kg/ha de NPK, 80 kg/ha d'urée). La valeur monétaire des productions (vente, autoconsommation, dons) et des activités est estimée à 886 ¿ par exploitation par an, dont 80% pour les productions végétales, 5% pour l'élevage, 15% pour les activités extra-agricoles. L'assolement se compose de 30% de coton, 55% de céréales (sorgho, mals et riz), 12% de légumineuses (arachide, niébé), 3% d'autres cultures (oignon, manioc, cultures légumières). (Résumé d'auteur)

    Authors: Penot, Eric; Hébraud, Caroline;

    Olympe est un outil de modélisation des exploitations agricoles permettant la simulation de leur fonctionnement et l'analyse prospective sur les revenus en fonction des choix techniques. La souplesse du logiciel Olympe permet d'adapter chaque cas en adaptant selon les cas le niveau de détail et d'analyse. Il permet de simuler différentes évolutions possibles d'une exploitation en fonction de choix des cultures et de décision d'affectation des facteurs de production (capital, travail, foncier) sur une période de 10 ans (et plus si nécessaire). Olympe fournit des prévisions de résultats économiques par système de culture, d'élevage ou d'activité aussi bien qu'au niveau global de l'exploitation, de trésorerie mensuelle, de temps de travaux: c'est donc un instrument à utiliser pour juger de la viabilité d'une exploitation et des choix techniques. Il peut également traiter des ensembles d'exploitations, dans les périmètres irrigués et mesurer ainsi les flux entrées/sorties et les possibilités d'évolution entre types d'exploitation. Un des intérêts du logiciel est de pouvoir réaliser avec le module "aléa" une analyse prospective sur un pas de temps suffisamment long pour mesurer les effets des variations de prix ou de productions sur le revenu global des producteurs, en particulier pour la prise en compte des spécificités des plantations pérennes. Après une réflexion sur l'intérêt de la modélisation sur les exploitations agricoles, sur l'identification des stratégies en fonctions des revenus et des risques attendus, l'objet de cette communication est de montrer la façon de manier le module aléa pour la construction de scénarios probables, ou de fourchettes potentielles de situations en fonction de la volatilité des prix internationaux, ou des accidents climatiques comme une année "El nino". Ces scénarios peuvent être utilisés par les décideurs, développeurs ou bailleurs de fonds pour mieux cadrer les actions des projets de développement futurs ou mieux en mesurer les effets attendus.

    Le projet SIRMA (Economies d'eau en sytèmes irrigués au Maghreb) conduit des actions de recherche-intervention qui ont pour but de construire avec le monde professionnel agricole des innovations techniques, des outils économiques et des arrangements institutionnels pour une meilleure valorisation de l'eau agricole. Le projet a également pour ambition de contribuer à la formation initiale des ingénieurs agronomes et à la formation continue du monde professionnel. Le 3e atelier régional du projet a été l'occasion de présenter des résultats scientifiques et techniques pour l'ensemble des terrains concernés au Maghreb. La présentation des résultats a été précédée d'un exposé de la problématique de chaque terrain par un représentant des agriculteurs. (Résumé d'auteur)

    Authors: Penot, Eric; Hébraud, Caroline;

    Olympe est un outil de modélisation des exploitations agricoles permettant la simulation de leur fonctionnement et l'analyse prospective sur les revenus en fonction des choix techniques. La souplesse du logiciel Olympe permet d'adapter chaque cas en adaptant selon les cas le niveau de détail et d'analyse. Il permet de simuler différentes évolutions possibles d'une exploitation en fonction de choix des cultures et de décision d'affectation des facteurs de production (capital, travail, foncier) sur une période de 10 ans (et plus si nécessaire). Olympe fournit des prévisions de résultats économiques par système de culture, d'élevage ou d'activité aussi bien qu'au niveau global de l'exploitation, de trésorerie mensuelle, de temps de travaux: c'est donc un instrument à utiliser pour juger de la viabilité d'une exploitation et des choix techniques. Il peut également traiter des ensembles d'exploitations, dans les périmètres irrigués et mesurer ainsi les flux entrées/sorties et les possibilités d'évolution entre types d'exploitation. Un des intérêts du logiciel est de pouvoir réaliser avec le module "aléa" une analyse prospective sur un pas de temps suffisamment long pour mesurer les effets des variations de prix ou de productions sur le revenu global des producteurs, en particulier pour la prise en compte des spécificités des plantations pérennes. Après une réflexion sur l'intérêt de la modélisation sur les exploitations agricoles, sur l'identification des stratégies en fonctions des revenus et des risques attendus, l'objet de cette communication est de montrer la façon de manier le module aléa pour la construction de scénarios probables, ou de fourchettes potentielles de situations en fonction de la volatilité des prix internationaux, ou des accidents climatiques comme une année "El nino". Ces scénarios peuvent être utilisés par les décideurs, développeurs ou bailleurs de fonds pour mieux cadrer les actions des projets de développement futurs ou mieux en mesurer les effets attendus.

    Le projet SIRMA (Economies d'eau en sytèmes irrigués au Maghreb) conduit des actions de recherche-intervention qui ont pour but de construire avec le monde professionnel agricole des innovations techniques, des outils économiques et des arrangements institutionnels pour une meilleure valorisation de l'eau agricole. Le projet a également pour ambition de contribuer à la formation initiale des ingénieurs agronomes et à la formation continue du monde professionnel. Le 3e atelier régional du projet a été l'occasion de présenter des résultats scientifiques et techniques pour l'ensemble des terrains concernés au Maghreb. La présentation des résultats a été précédée d'un exposé de la problématique de chaque terrain par un représentant des agriculteurs. (Résumé d'auteur)
