Mongolia’s dzud risk is a coupled climate–rangeland–market problem, not a winter-weather problem alone
WHAT THE EVIDENCE SAYS
An integrated climate–rangeland–society model reproduced historical livestock mortality, hay production and herd size reasonably well, then projected intensifying dzud risk into the 2030s under baseline pathways. In the modeled export-enhanced pathways, herd pressure falls and annual livestock mortality is reduced from roughly 8–11 million sheep units to about 1–3 million.
WHY IT MATTERS / OUR READ
The important mechanism is coupled vulnerability: summer drought, winter exposure, forage reserves, stocking pressure, markets and governance interact. Adaptation therefore cannot be reduced to better weather forecasting or emergency hay alone; the herd and market system changes the ecological risk.
CAVEATS / UNCERTAINTY
This is a national scenario model, not a field trial of export policy. Household heterogeneity, market access, infrastructure, prices and distributional effects remain consequential, and the modeled pathway should not be read as a universal prescription for pastoral systems.

A national model projects sharply higher livestock losses under baseline pathways, while scenarios that constrain overstocking through stronger export pathways substantially reduce modeled mortality.
