| A network of 42 sheep farms (including 13 in organic farming (OF)) shows that the gross margin per ewe is 24% lower in OF in the mountains because of high food costs and comparable in the lowlands because of the high level of food self-sufficiency based on the cultivation of fodder and grain; incomes are identical when structural costs are comparable. An analysis of four demonstration farms shows that, given the different conditions, specific livestock management is required depending on the presence of tillable land or not. If their proportion is limited, lambings are equally distributed between spring and autumn in order to maximise fodder self-sufficiency. When crops are possible, lambings are focused on autumn (with good sale prices), which requires... |

| Sixteen meat sheep farms (nine conventional and seven organic) in the centre of France were surveyed to evaluate their economic and production performances (previous interviews) and their strategies related to animal health with particular attention to internal parasites (present interview on health strategies). The organic farms were surveyed in mid-September 2006 and the conventional ones in October 2007. Each interview (1½ or 2 h) included a visit of the farm (with the collection of faeces for evaluation of internal parasites), followed by an open discussion on sheep production and health problems, and parasitic infections, in particular. The discussion was recorded and then transcribed into a word processor file and analysed. The farmers agreed on the... |

| In Europe, the pervasive use of pesticides in agricultural areas has led to the deterioration of the quality of groundwater and surface water, resources earmarked for human consumption. The aim of the European Water Framework Directive 91/474 is to restore the “good ecological status” of surface water and to protect water that might be used for drinking water production by 2015. Interactions within the soil determine the fate of environmental pesticides. Water resource contamination may persist for a long time after the last use of pesticides (i.e., atrazine). Pesticide persistence is highly variable. The fate and persistence of pesticides in the environment depend on agricultural pesticide practices and on soil interactions, which are interrelated... |

| This seminar confirmed that less greenhouse gas (GHG) is emitted per unit area under organic agriculture than under conventional agriculture, and that our eating patterns have a strong impact on factors involved in climate change. Moreover, it shed new light on and contributed original information to a variety of fields. The two major advantages of organic farming in terms of the mitigation of GHG emissions are its ability to store carbon in the ground and the non-use of synthetic nitrogen fertilisers. Means for improving practices and research priorities were identified. |

| We have undertaken in this work an evaluation of the greenhouse gas (GHG) emissions and the Non-Renewable Energy (NRE) consumption on a sample of 1250 farms-years, operating in sheep meat production, in either organic (OA) or conventional (CA) agriculture, over the period 1987 to 2012, based on the Life Cycle Assessment (LCA) method. There was no significant difference for NRE consumption (79.6 MJ in OA and 79.7 MJ in CA, per kg of carcass); indeed the gains in OA thanks to a lower use of chemical fertilizers and purchase of lesser concentrates feed were offset by the higher level of mechanization (here fuels and equipment). For GHG emissions, we found a significant difference of 5% beneficial to organic production systems (31.1 vs. 32.7 kg CO2 eq/kg... |
