What does ZUD mean?

A zud or dzud is a Mongolian term for an extremely snowy winter in which livestock are unable to find fodder through the snow cover, and large numbers of animals die due to starvation and the cold. The term is also used for other meteorological conditions, especially in winter, that make livestock grazing impossible. The economy of Mongolia has long been heavily dependent on pastoral farming, and harsh zuds can cause economic crises and food security issues in the country.
