Team COMETE – Design, modelling and evaluation of livestock farming systems

COMETE objectives are:

  • To assess the technical, economic, and environmental performances, the ecosystem services, and the efficiency of herbivore farms over time, including a territorial dimension;
  • To understand the links between farm practices, biological functions, and ecosystemic services (production and regulation services such as biodiversity preservation);
  • To design, test and evaluate innovative herbivore farming systems within the framework of agroecology (e.g. minimising inputs, using diversity and complementarity between local resources, promoting ecosystem services);
  • To identify locks and levers enabling to improve the efficiency and the resilience of herbivore farming systems.

 

COMETE studies farming systems and their components (herd and batches of animals, forages and the crop system, means of production, production practices), with a focus on systems based mainly on grazing livestock in less-favoured and mountain areas, including mixed systems combining several species or productions (animals, plants).

COMETE research combines observations on commercial farms and experiments at the system level on long-term, as well as systems modelling, in an iterative approach. Through the monitoring over years of the multi-performances, in farms network and in experimental units, COMETE assesses performances dynamics (stability, resilience...) in response to economic, climatic and biological changes and/or hazards, and analyses the synergies or antagonisms (trade-offs) between ecosystem services. Modelling is used to design and assess farming systems ex ante, to understand and test trade-offs. Models are regularly enriched with the data collected in commercial and experimental farms. The assessment of the sustainability of farming systems relies on indicators of practices or performances (observed and/or modelled) which are integrated in multicriterion evaluations.The design of sustainable systems considers, as far as possible, the point of view of farmers and the specific needs of the sectors (types/quality of products and their marketing), in a participative approach at the territorial and/or sector scale.
