The structures and the technical and economic results of 12 farms practising organic farming (Org) (eight upland and four lowland) were compared with those of 25 conventional farms (Conv) (14 and 11), over three years (2002-2004). The Org farms had smaller structures, fewer workers, and lower numerical productivity, especially in uplands (-16 % on average over three years) owing to lower flock intensification and sometimes because of sanitary problems. The key questions were above all economic with (i) the high cost of concentrates, the consumption of which remained high (extra cost per kg from 40 % to 60 % in 2004), and (ii) steadily decreasing average premium on meat price; only 9 % in uplands and 2 % in lowlands in 2004. Hence the gross margin per ewe... |

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... |
