奢侈羊绒背后的生态危机与蒙古牧民的自救之路
In the hushed showrooms of Milan and Paris, cashmere is marketed as the pinnacle of effortless luxury — whisper-soft, timeless, and ethically opaque. Yet the journey of that fibre begins on the wind-scoured steppes of Mongolia, where intensifying global demand has fundamentally reshaped both a nomadic economy and an ancient ecosystem. The country now supplies roughly 40% of the world’s raw cashmere, a figure that has nearly tripled over the past two decades as mid-market retailers and fast-fashion cycles have democratised what was once a niche product. This surge, however, carries a heavy environmental ledger, forcing a reckoning between international supply chains and the carrying capacity of one of the planet’s most fragile grasslands.
Cashmere goats are extraordinarily efficient browsers; their cloven hooves churn the thin topsoil while their sharp teeth graze plants far closer to the root than sheep or cattle. A three-decade study by the Mongolian government’s rangeland monitoring programme — which researchers discreetly acknowledge as underreported — has documented that goat numbers have swollen from 5.5 million in 1990 to over 27 million today. The consequence is not simply overgrazing but a self-reinforcing spiral of desertification: as vegetation cover declines, soil moisture evaporates more rapidly, spring dust storms intensify, and winter cold snaps kill weakened livestock, compelling herders to increase herd sizes further in a desperate hedge against mortality. Remote sensing data from the National University of Mongolia indicates that nearly 70% of pastures in the central and desert-steppe zones now show symptoms of moderate to severe degradation, a threshold beyond which natural recovery becomes improbable without decades of rest.
