The transition to more numerous and more efficient organic pig farms requires the development of alternatives that do not use syn-thetic hormones for the synchronization of estrus to facilitate gilt batch management. The objective is to test two natural substitutes for syn-thetic progestagens used for cycle synchronization: the fruit of the chaste tree and walnut leaves. The hypothesis is that the incorporation of phytoprogestagens in the feed ration would extend the luteal phase of gilts and that its cessation would induce a resumption of fol-licular growth and a synchronization of estrus.

Within the context of major climatic uncertainties, the sustainable mobilization of feed resources for animals on ruminant farms is questioned in terms of quantity and quality. The use of new plant re-sources may prove to be one of the alternatives for sufficient and sustainable production in the future. The SourceN project explores the extent to which atypical resources from the natural capital of ruminant farms can be mobilized in terms of fodder supplementation and animal "health value" without compromising their sustainability and their role as habitats for biodiversity.

Changes in scale of OA in terms of beekeeping still face many challenges: availability of organic food resources, control of biological pests (including Varroa), organic genetic beekeeping resources, etc. Genetic improvement is one of the levers used to address these challenges. It is important to determine how to select honeybees to meet the expectations of organic beekeepers and to evaluate the relevance of selection strategies specifically devoted to organic farming.

Whereas certain organic plant crops are in full expansion, organic animal production is struggling to develop in France’s overseas departments and regions (DROM). The aim of this project is to identify possible development paths for organic farming in the DROM, both for organized sectors and those that are more dispersed.

Digital technology could play an important role in the organic agriculture scale change by promoting sharing and the mobilization of knowledge to (re)design organic systems within a diversity of contexts.

French organic wine production has considerably increased over the past ten years, but the enthusiasm of producers is dampened by a wide range of constraints and an increased risk of crop loss due to fungal diseases. The use of resistant varieties is a possible solution in the context of organic practices guided by the limitation of inputs, both in the vineyard and in the wine cellar.

LAPOESIE is a transdisciplinary project that aims to analyze the feasibility and the aggregated value of combining organic arboriculture and livestock.

For almost a decade now, in contrast to the dominant conventional model spawned by the green revolution, two Indian states launched a wide-ranging reform of their agricultural system: Sikkim was entirely converted to organic agriculture, and in Andhra Pradesh, Natural Farming now counts more than 600,000 farmers.

This project stems from the observation of communication problems and differences in approaches between organic livestock farmers and their veterinarians, at a time when issues of animal health, well-being and global health are of the utmost importance in the challenges facing us in the decades to come.

Territorial actions aimed at relocating food supply and/or promoting more sustainable forms of agriculture are more and more numerous. Despite this shared enthusiasm, visions may differ depending on the actors.
