| Ce colloque a confirmé que l’agriculture biologique émet moins de gaz à effet de serre (GES) par unité de surface que l’agriculture conventionnelle, et que nos habitudes alimentaires ont un fort impact sur les facteurs intervenant sur le changement climatique. Il a par ailleurs apporté un éclairage nouveau et desinformations originales dans de nombreux domaines. En matière de mitigation des émissions de GES par l’agriculture biologique, les deux atouts principaux de cette dernière, tels qu’ils sont ressortis de ce colloque, sont la séquestration de carbone dans le sol et la non utilisation d’azote de synthèse. Des pistes d’amélioration des pratiques et des orientations de recherche sont identifiées. |

| Sustainability rests on the principle that we must meet the needs of the present without compromising the ability of future generations to meet their own needs. Starving people in poor nations, obesity in rich nations, increasing food prices, on-going climate changes, increasing fuel and transportation costs, flaws of the global market, worldwide pesticide pollution, pest adaptation and resistance, loss of soil fertility and organic carbon, soil erosion, decreasing biodiversity, desertification, and so on. Despite unprecedented advances in sciences allowing us to visit planets and disclose subatomic particles, serious terrestrial issues about food show clearly that conventional agriculture is no longer suited to feeding humans and preserving ecosystems.... |

| One of the keystones of the organic orchard is the cultivar choice as one element of pest and disease control. However, few exhaustive data sets concerning the cultivar susceptibility to pests and diseases are available for growers. In order to identify cultivars adapted to organic production methods, the susceptibility to scab, aphids and powdery mildew and the agronomic properties of 36 cultivars were assessed in four French sites under different pedo-climatic conditions. Different levels of susceptibility to scab were observed for 23 scab Vf-resistant and 13 other cultivars. In the North of Frence where Vf resistance is overcome, the Vf cultivars displayed different levels of scab severity. A high variability in the susceptibility to aphids was observed... |

| The loss of biodiversity by intensification of agricultural practices is a major environmental issue that calls for the design of new cropping systems. For instance, negative effects of tillage on earthworm populations have been reported. However, few field studies have compared full cropping systems. Here, we assessed diversity, density and biomass of earthworm populations for 3 years. We use a combinedmethod involving a diluted solution of allyl isothiocyanate to expel earthworms followed by hand sorting. In a long-term trial, we compared 3 systems: (1) a conventional system, (2) a direct seeding living mulch-based cropping system, named a living mulch cropping system, and (3) an organic system. These three cropping systems differed in terms of soil... |

| Les techniques culturales sans labour et l'Agriculture de Conservation (AC), fondées sur une perturbation minimale du sol, le maintien d'une couverture végétale en surface et une diversification des rotations et associations de cultures, se développent rapidement au nord et au sud. Leur émergence procède souvent d'un processus d'innovation original, fondé sur un apprentissage permanent et adaptatif au sein de réseaux sociotechniques novateurs, qui bouscule les schémas linéaires de conception et transfert des innovations. Les modifications du fonctionnement de l'agrosystème en AC sont susceptibles de fournir des services écosystémiques, mais la mise en œuvre délicate de ces techniques peut en diminuer les performances, notamment en augmentant la dépendance... |

| Climate change and the recent financial crisis clearly show that humans have entered the anthropocene, an unprecedented era of fast and possibly dangerous changes. Unprecedented changes call for unprecedented thinking. Indeed, agricultural research has been for too long driven solely by the need for higher yields using classical agrosciences, whatever the adverse ecological effects. Agricultural research needs the input of other sciences such as ecological, economic, social and political sciences. These social sciences emerged in agricultural research a few decades ago, but there are currently no precise trends and data on the speed of emergence of specific topics. Therefore, here we report: (1) an analysis of the emergence of topics in the journal... |

| This work is devoted to the evaluation and utilization of the STICS intercrop/sole crop model taking into account the European environmental variability within an organic farming framework. The model ability to simulate intercropping systems was evaluated on the network of the INTERCROP EU project experiments. We first realized the difficulty to simulate relevant absolute production values in spite of a satisfactorily phase of parameterisation in conventional farming experiments. We attributed most of the discrepancies between simulations and measurements to the non accounting of biotic stresses. However, the relative values and in particular the Land Equivalent Ratios draw to the same results for simulation and observation, i.e. the global advantage of... |

| We investigate empirically the role of moral and social concerns in farmers' decision to adopt integrated crop protection (IP) and organic farming (OF). A survey questionnaire has been sent to 1286 fruit-growers and vegetable producers located in the French areas of Alpes de Haute Provence, Hautes-Alpes and Vaucluse. Analysis of individual responses (N = 243) shows that, although economic concerns play a strong role, a significant number of respondents give high importance to moral and social ones. We also examine how these considerations matter according to different crop protection strategies, that is, conventional farming, IP and OF. Using a multinomial logistic regression, we find that (1) social concerns (e.g., showing to others one's environmental... |

| We use survey data to provide some empirical information about considerations regarding moral and social incentives among a sample of French fruit-growers and vegetable producers(N=243). Our results show that, beyond the strong role played by economic incentives, a significant number of respondents give high importance to moral and social incentives. We also examine how these behaviors matter according to different crop protection strategies, that is, conventional farming, integrated crop protection (IP) and organic farming (OF). Using a multinomial logistic regression, we find that (1) social incentives (e.g., showing to others one’s environmental commitment) drive both IP and OF adoption, (2) moral incentives (e.g., do not feel guilty about one’s... |

| Les systèmes d’élevage ovins et les caprins, comme les autres productions animales, sont confrontés aux multiples défis environnementaux : limiter les nuisances et contribuer positivement à l’entretien ou à l’amélioration du milieu. Les travaux de l’INRA, et de ses partenaires, se sont largement impliqués dans ces questions en considérant ces élevages de petits ruminants comme faisant partie d‘agroécosystèmes complexes. Cette synthèse collective rassemble, en privilégiant les niveaux d’approche, les actions dans lesquels l’INRA intervient. Considérant tout d’abord les grandes tendances sur les effectifs d’animaux et leur répartition géographique, les adaptations ou les disparitions de ces élevages se repèrent par les approches technico-économiques. Dans ce... |

| Une des façons d’améliorer l’efficacité de l’effet bélier est de se placer dans de bonnes conditions d’élevage. Ainsi, la proportion de brebis dont l’ovulation est induite augmente lorsque la date d’introduction des mâles est plus tardive (55% en avril vs 81% fin mai, p<0,05) et avec l’allongement de l’intervalle entre le tarissement et la mise en lutte : de 29% à 84% (p<0,001) pour des intervalles respectifs de 22 et 86 jours. La fertilité de ces brebis est également meilleure fin mai qu’en avril (86% vs 39%, p<0,01) et lorsque l’intervalle écoulé depuis le tarissement est accru : respectivement 55% et 81% (p=0,09). Enfin, le moment d’apparition des premières ovulations fertiles est retardé chez les brebis en état corporel faible car elles... |
