Multi-species swards and multi scale strategies for multifunctional grassland-base ruminant production systems: An overview of the FP7-MultiSward project

MultiSward aimed to conceive, evaluate and promote sustainable ruminant production systems based on the use of grass lands with a high leve! of multi-functionality by the concerted use of diverse multi-species swards, diverse plant communities at farm and landscape levels, and diverse production systems. It was demonstrated that the use of sown multi-species swards combining legumes and grasses as weil as shallow and deep-rooting species are as productive as fertilized grasses; they allow high levels of animal performance and these results are not conflicting with the delivery of a range of services. For permanent grassland, differentiated grassland management and climate variables influencing functional diversity criteria linked to ecosystem services were identified. Severa! innovations in grazing management were proposed to enhance the benefits of grassland-based systems. Different operational indicators sets easily implemented at farm and at landscape levels were developed and demonstrate the contribution of grassland-based systems and effects of management on the provision of food and environmental services including the maintenance of farmland biodivers ity. Modelling of severa! policy options and priee hypothesis showed that extensive grassland abandonment may be prevented by area payment supporting grassland use, whereas lower Common Agricultural Po licy support payments and higher commodity priees may cause less control of land use. In conclusion, MultiSward provided a detailed EU-wide and multifunctional-orientated overview of grassland-based ruminant production systems thus opening the opportunity to define, on a new basis, the contribution of ruminant production on grassland to economie returns for farmers, biodiversity conservation and provision of ecosystem services. This willlead to a better consideration and acceptance ofthese ruminant production systems by EU citizens and farmers, and will contribute to secure optimal European grassland acreage
