As quickly as Mongolia opened its borders following a interval of COVID-19 isolation, Taiwanese nationwide Cheng Li-yi boarded a aircraft and flew 3,000 kilometers to the grasslands. Her mission? To plant bushes.
Cheng’s Compassion Basis has an bold goal: to plant one billion bushes.
“We wish to make extra environmental contributions to the worldwide village,” biology main Cheng instructed RFA from Mongolia, the place sandstorms often flip the sky orange amid the environmental scourge of desertification.
“Seventy % of land in Mongolia has succumbed to desertification,” Cheng mentioned, citing rising swathes of land denuded of forests, with the delicate steppe ecosystems collapsing below unsustainable strain.
“Again then, there have been bushes all over the place, however now they’re all gone,” she recalled of a visit she made to mountains close to Ulaanbaatar again in 1990.
Deforestation signifies that when torrential rains fall, floods collect rapidly, washing a lot of the topsoil with it. A current flash flood wrought havoc with Cheng’s tree-planting mission.
“The torrential rain fell for about two hours continuous, and flash floods got here instantly, breaking by the [perimeter] wall in a number of locations,” Cheng mentioned.
“It seems that there was once a river passing by the world,” she mentioned. “When it rains, as a result of there aren’t any extra bushes within the higher valleys, the water instantly will get funneled down the previous river mattress.”
“When it does not rain, there is no water — these are the implications of an absence of forest regulation,” Cheng mentioned.

Overgrazing
The land has additionally come below relentless strain from overgrazing by 60 million head of livestock and extractive industries like mining.
Nevertheless it’s not sufficient simply to dig some holes and put saplings in them.
Tree-planting is a exact artwork that wants a localized technique in tune with native situations, because the authorities within the Chinese language area of Inside Mongolia discovered to their price after sinking large sums into planting poplars, solely to seek out the species did not thrive there.
“There are lots of strains within the wilderness, which have each financial and well being advantages, that may propagate from underground stems — these are good species for afforestation,” Cheng mentioned.
Among the many native species Cheng’s mission favors are sea buckthorn and Siberian elm, which already cowl an space equal to 10 soccer pitches on the mission, the place water towers, wells, irrigation pipelines, yurts and different services have sprung up alongside the saplings.
Cheng’s bushes are planted in biodegradable reservoirs soaked in water, conserving the seedlings watered for round a month, cooling the basis ball, and defending the susceptible seedlings from wind and sandstorms.
“The [reservoirs] regularly decompose, caring for the bushes within the course of,” Cheng mentioned, noting that present hose watering strategies utilized in China generate an excessive amount of plastic waste to be sustainable.
Livestock eat bushes
However there’s one other hazard — livestock.
“It is fairly regular for livestock to roam freely and eat bushes in Mongolia,” Cheng mentioned. “So we’re working with Renzhou Social Enterprise to develop a tree sleeve fabricated from the identical materials because the water reservoirs, defending [the seedlings] from being eaten by animals.”
Whereas the Mongolian authorities is urgent forward with its personal tree-planting plan, which goals to plant one billion bushes by 2030, Cheng mentioned most of the plantations are in mining districts, and that many fail to thrive within the absence of adequate watering after planting.
Cheng herself is flourishing on the work, nevertheless.
“We’re taking the initiative to vary the atmosphere by arduous work, somewhat than passively enduring extremes,” Cheng mentioned. “We have now to work arduous, take this chance; there is no different possibility.”
“I feel it is higher than turning into a local weather refugee.”
