| الوصف: | From the second half of the 20th century onwards, the continuous specialization of agricultural holdings and production basins led to numerous biogeochemical and economic imbalances (nutrient cycles opening, dependence on protein-rich raw materials for animal feed, etc.). The implementation of cooperation to promote crop-livestock interactions on the scale of several farms appears to be an alternative to optimize the use and preservation of resources on a specific territory. Our study was carried out as part of the POEETE project (Crop-Livestock on a Farm and Territory scale) PSDR 4 in the Burgundy-Franche-Comté and former Rhône-Alpes regions. Our objective was to make an economic estimation of the implementation of crop-livestock interactions on the scale of several farms in accordance with agroecology. A first study on the analysis of the transaction costs of four cooperative approaches between farms on crop-livestock interactions highlighted the importance of interpersonal relationships and the specificity of the commodity or production tool exchanged in the cost distribution. The second axis focused on estimating the economic interest of a crop-livestock interaction approach between a field crop farm and a typical livestock farm in straw-manure exchange. This cooperation aimed at improving the fertility of the cultivated soils and reducing the use of synthetic fertilizers. The third axis focused on a short alfalfa hay chain to improve soil fertility, reduce inputs and risks of grain farmers and promote a local protein supply for farmers. We were able to establish a price ranged from 10 to 18 €/t for the purchase/sale of manure and a range of 167-189 €/t for alfalfa hay. In both cases, farmers (stockbreeders and grain farmers) could find an economic interest in the exchange even if it remains moderate. These initial simulations would need to be supplemented with other test cases to observe the effect of these interactions on a wider range of systems and to be able to assess regional supply and demand. ; A ... |
