Organisation of the pastoral territory and grazing management: joint modelling of grazing management practices and plant cover dynamics

摘要: Abstract The authors propose an original modelling methodology to investigate grazing systems, which confronts and combines two conceptually methodologically different approaches that link contrasting points of view on the system: a farmer's organisation changes in plant cover states farm territory. consists multivariate analysis enabling be interpreted light practices by applying model farmer behaviour for action. One objective was determine relative role vegetation decisions management, particular highlighting strategic rules adaptation change. research is based 2-year case study sheep using chiefly native some improved grass calcareous hills inland Provence southeastern France. representative one meat farming types France producing mainly housed lambs raised exclusively suckling concentrate sold at 100–120 days carcass weight 15–18 kg. successive years were selected their greatly weather conditions. In this situation, adjustments made shown peripheral consisted either combining use certain fields, or securing complementary fields from neighbours.
