| The compared energy analysis of various farming systems makes it possible to carry out an approach of their sustainability through their faculty to produce energy in the form of livestock or vegetable products, while limiting the resort to non renewable energies. This study was carried out from the results of 38 farms in meat sheep and dairy cow production including 13 in organic farming. It focuses on livestock production, being acquired that the presence of cash crops raises considerably the energy effi-ciency. The main energy expenditure are the bought food, fertilisers and mechanization. The average en-ergy efficiency of the dairy cow farms is 0.59 and there is no difference between organic and conven-tional farming. In sheep production, the average is... |

| In the dairy mountain areas, natural constraints and the end of the quota system are sources of difficulties and challenges for the dairy production. High added value schemes, such as organic farming could help farmers and processors to face these challenges. The “Montagne Bio project”, funded by the French Ministry of Agriculture studied and defined the conditions for the success of this development. We studied dairy farmers’ views on organic production, described farm trajectories before and after conversion, and identified factors that contribute to the success or the failure of a conversion or of a collective development project. We tested and assessed a method to carry out projects for the development of organic farming in rural areas and built tools... |

| Eight highland dairy farms in the French Massif Central (4 organic and 4 conventional) were surveyed from 2000 to 2005 to understand the forage system functioning and the specificities of organic farms. During this period two important droughts occurred, which highly affected the fodder self-sufficiency of the organic farms, having consequences on more than a year of production. The conventional farms were less affected than the organic ones, and the farmers developed varied strategies including a reduction of the LU and the use of more maize. To maintain the stability of the milk production, organic farms had to increase the reliance on external fodder resources. The lack of security forage stores can explain the sensitivity of these farms and their... |
