Dzud is a Mongolian word indicating harsh winter conditions. In more detail, dzud is defined, biogeophysically, as anomalous climatic and/or land surface (i.e., snow/ice cover and lack of pasture) conditions that lead to reduced accessibility and/or availability of pastures, and ultimately to significant livestock mortality during winter-spring.
