Abstract: Until the 1950s, crop-livestock systems (combination of crop and livestock farming) ruled France. Since then, specialized systems less numerous and bigger have been prevailing. The objective of this study is to analyse the impacts of price variations and land expansion on crop-livestock farming systems. Simulations were run using the bioeconomical model Orfee applied to three farm types in Lorraine, Normandie and Midi-Pyrénées. The Norman context seems to be the most stable, as a result of milk profitability. But, milk production is stopped for price drop higher than -20%. The livestock-crop share is the most sensitive to price variations in the Midi-Pyrénées system where the returns per worker of the crops and the beef system are close. Beef suckler farms keep livestock on permanent pasture regardless of the price variations.
