Taking the steps toward sustainable livestock: our multidisciplinary global farm platform journey.

Implications • The Global Farm Platform was conceived and established to explore multidisciplinary strategies for optimising the sustainability of ruminant livestock systems around the world. • International sustainability issues are common, but the solutions are often region-specific; therefore, our farms, situated across all major agroclimatic zones, are a unique resource worldwide. • Each farm is following "steps to sustainable livestock" to improve their production system(s), thereby developing robust metrics to progress economic, environmental and social viability. • The consortium works collaboratively to improve the sustainability of ruminants, which we argue are a vital component of global food systems, delivering both human and planetary health.
