Due to the complex interactions among determinants for livestock production, the future signal of water-related risks to this sector is unclear. Globally, 10%  of pasture areas are projected to be vulnerable to climate-induced water scarcity by 2050 . Water use efficiency gains through elevated CO2 concentrations have the potential to increase forage quantities, though effects of nutritional values are ambiguous . In addition, spatial shifts in temperature/ humidity regimes may shift suitable regions for livestock production, opening up new suitable areas for some regions or encouraging shifts in specific breeds better adapted to future climatic regimes  .
