Water stress in crops reduces plant health and yield. Dry conditions also make crops more vulnerable to other threats, like pests and diseases. Seasonal drought results in annual crop losses, with potential for long-term effects to perennial crop health. Dryland production — or crop production without irrigation — is most vulnerable to drier conditions and drought. However, if there is not enough water for irrigation, crop damage and losses will happen across all production types. Livestock health is also affected by drier conditions, particularly if temperatures are also high. In hot and dry weather, livestock will eat less, and reproduction rates drop. Grazing livestock can also be affected if pasture and rangeland productivity decreases. Forage quantity and quality will be reduced, as will water quality and availability.
