Conversion to OF was simulated for four specialized suckler-beef systems by coupling an economic optimization model (“Opt’INRA”) with a model assessing non-renewable energy (NRE) consumption and greenhouse gas (GHG) emissions (“PLANETE”). After adaptation of the production system, and based on average prices over 2004–2008, we analyzed the productive, environmental and economic impacts of the conversion process. The ban on chemical fertilizers led to a drop in farm area productivity. For these specialized farms, meat production decreased by 18% to 37% depending on initial level of intensification. The reduced use of inputs results in a 23% to 45% drop in NRE consumption/ha, 5–20% of which is a drop in NRE per ton of live weight produced. Its methane... |
