Globalisation of environmental, economic and social issues induces 28 rapid changes in agricultural systems and land use. Competition or synergies 29 between different land users and farming systems are important issues. In this 30 context, the future of livestock farming systems (LS), which have often been 31 often described as having negative impacts on the environment, is debated. An 32 international comparison of processes of change in LS within seven territories 33 has been carried out to understand the driving factors and their impact on LS 34 dynamics and their relation to other land use management. As a common 35 paradigm, these studies used the participatory multi-agent modelling. A 36 synthesis of these models allowed describing a common conceptual model of 37 processes of change, to study scenarios and to compare the participatory 38 2 processes. Results show that common global drivers have different impacts on 39 livestock farming system at a local level but that LS are most often in negative 40 match with other activities in local development options. To be competitive in 41 land-users perceptions, livestock systems have to be assessed in a more 42 integrative approach combining economic, social and environmental 43 assessment as their impacts occur at various spatial and temporal levels.
