Urban Sand Clears, but Sandstorms’ Impact on Herders Persists


Since 6 April, Damao Banner in Baotou City, Inner Mongolia, has been plagued by “blowing sand” almost every day. The worst was on the 10th, when a sandstorm lasted nearly five hours. Outside the window, the wind and sand blotted out the sun, and inside the house it was dim and lightless.
“We had to light the lamps even in broad daylight!” Brother Ma, who has been herding livestock in Damao Banner for decades, had rarely encountered such conditions. “I feel like this year has the most sandstorms—and the fiercest ones.”
On nearly 10,000 mu of grassland, Brother Ma’s family keeps over 400 sheep and more than 50 cattle. In ordinary circumstances, he would drive them out to graze and drink every day. But during a sandstorm, even people struggle to walk, so the animals eat fodder in their livestock sheds, and they have to wait until the next day for water.
Bordering Damao Banner is East Gobi Province, a major dust source area in Mongolia where the landscape is predominantly desert steppe. Yet Brother Ma pays little mind to the sand drifting in from his northern neighbours. What weighs on him far more is the state of his own grassland.

Grass roots anchor the soil and hold the sand in place. Once the grass is gone, the sand and soil beneath are stripped away.
I. Sand and Grass: “The Great Topsoil Migration”


It looked nothing like what I saw last September. How could a single winter have reduced it to bare ground?
The answer lies just nearby. Right beside the bare patch stand a motorised well and a water trough, and the herds come here to drink every day. The constant trampling has left the ground extremely loose, almost entirely devoid of vegetation.
Unlike the partially preserved nomadic traditions of the collectivisation era—when herders and their animals moved with the seasons through the year—after the grass–livestock dual contract system was gradually implemented in the 1990s, wire mesh fencing carved out individual households’ grazing ranges, and sedentary pastoralism had become the norm across the grassland. Although Dulan’s family owns 6,000 mu of grassland and has rented another 4,000 mu from a neighbour, the routes and distances their livestock can roam have been greatly curtailed.

Some of the wind-blown sand slows down when it reaches taller grass, settling and piling up at the base of the plants. If you walk along the bare ground, you will notice that on stretches where the vegetation cover is better, each clump of grass roots is slightly raised by the accumulating sand—higher in the middle, tapering at the edges—so that together they look like a field of miniature sand dunes.
Dulan has put this to practical use. For the past five years, he has fenced off more than 100 mu of grassland near his house, keeping his livestock out to both block further sand encroachment and anchor part of the topsoil.


The topsoil that the grass roots cannot intercept becomes a new source of sand during sandstorms and strong winds, and further alters the grassland’s original vegetation and environment. In The Logic of the Grassland: A Sequel, Han Nianyong, a researcher at the Chinese Academy of Sciences, calls this phenomenon “The Great Topsoil Migration”.
Through years of field research, Han Nianyong and his team found that topsoil migration has caused plant species once confined to the arid-zone grasslands of western Inner Mongolia to appear in the semi-arid eastern regions. Annual and biennial plants have proliferated explosively across wide areas; although vegetation cover has increased somewhat, forage quality and vegetation stability are declining…
This matches Dulan’s own observations. In the past, he could name over twenty different grass species on his land; now barely ten remain. The perennial standing-dead thatch layer—what survives the winter and lets livestock build up their condition on dry grass before the spring green-up—is dwindling too. Without that thatch layer to shield the ground, the grassland’s ability to absorb and permeate water has diminished, and the exposed area has grown enormously, leaving the land far more vulnerable when the spring winds and sand arrive.

II. Sand and Water: The Ever-Drier Grassland
“When did the sandstorms begin?” I asked Dulan.
“Since 2000,” he said. Almost in tandem, the flowing surface water sources on his family’s grassland vanished.
Looking at the grassland that has yet to show its spring green-up, with its patchy bald spots of bare ground, it is hard to imagine that thirty years ago several rivers—Jirengol, the Xilin River, and others—converged here, making the land rich with grass and water. People say that in summer, driving cattle down to the riverbank to drink, you had to watch every moment lest an animal sink into the silt of a river bend. But once a reservoir was built upstream, the flow downstream dropped sharply. Dulan remembers clearly: the river ceased to flow altogether from 1999.

Without surface water, livestock must rely on motorised wells to pump groundwater. Yet as water-hungry industrial and agricultural development on the grassland has steadily increased, the water table has been affected too.
Brother Ma in Damao Banner recalled that copper mining in the 2000s consumed vast quantities of groundwater; even the shallower wells on herders’ land stopped yielding water. Only after the government intervened and the mine’s deep wells were shut down did the water table gradually recover. Another deep well in the village is dedicated exclusively to irrigating the fodder cropland, which has left the surrounding grasslands even drier.
Dulan remembers that 2015 was another drought year, and the following spring the sandstorms in East Ujimqin Banner were especially fierce. Sand stung people’s and animals’ eyes and coated their bodies. When livestock grazed, they swallowed the sand clinging to the grass along with the grass itself. At the worst of the blowing sand, a sheep lying on the ground could be buried in sand before you blinked—you had to grab its legs in time, haul it out of the drift, then keep brushing the sand off its fleece.
The cascading loss of flowing surface water sources and the overdraw of groundwater have made the grassland’s condition worse by the year, deepening its reliance on rainfall that is unevenly spread in time and space and unpredictable. When drought strikes, herders are left all the more exposed to sandstorms.
Brother Ma’s family, battered by last summer’s drought, had been hoping for early rain this year so the grassland could green up sooner. But the rain never came—only the sand. Since late March, wind and dust in Damao Banner have dragged on for nearly a month. Dulan’s grassland, by contrast, escaped drought last summer, and his family baled several thousand bundles of hay for supplementary feeding of the sheep and cattle. Yet this winter and spring almost not a drop of rain fell—a situation enough to drive anyone to despair.
