| Dexi-SH* is an ex ante multivariate model for assessing the sustainability of dairy cows grazing systems. This model is composed of three sub-models that evaluate the impact of the systems on: (i) biotic resources; (ii) abiotic resources, and (iii) pollution risks. The structuring of the hierarchical tree was inspired by that of the Masc model. The choice of criteria and their aggregation modalities were discussed within a multi-disciplinary group of scientists. For each cluster, a utility function was established in order to determine weighting and priority functions between criteria. The model can take local and regional conditions and standards into account by adjusting criterion categories to the agroecological context, and the specific views of the... |

| in the Massif Central. An organic suckler cattle farm network was set up in order to establish technical and economic references. In 2004, 22 farms were monitored (13 of which had been monitored since 2001). All of these farms are located in economically-depressed areas. One hundred percent of the fodder area is under grassland. Annual crops (cereals and a cereal/pulse mix) take up 13% of the farm area and are used as livestock feed. The stocking rate (1 Livestock Unit/ha of fodder area) is 20% lower on organic farms than on conventional farms. Organic farms use 33% less concentrates per LU, and the meat production/LU is 16% lower than for conventional farms. The poorly structured organic beef market forces organic farmers to sell most of their animals... |
