Reclaiming the desert

Herdsmen work to plant the vital seeds that will help hold back the encroaching sands

In May, everything comes to life on the Ruo'ergai prairie in Sichuan province. Tibetan herdsmen transport organic fertilizer and protective screens, sowing grass seeds to prevent desertification. Soon, the bare sand dunes are covered with a patchwork of green. Desertification is caused by multiple factors - climate warming, rainfall reduction, rodents and excessive grazing. Early April to the end of May is a vital time for sand control, because highland willow and grass have a higher chance of survival if sown at this time of year. Ruo'ergai county has a total of 128 sand control spots, where people set up tents and live during the two months. According to the county's environmental protection and forestry bureau, from 2007 to date, 23,619.79 hectares of sandy grassland have been harnessed for sand control, accounting for 29 percent of the total desert in the region. By 2020, the county is expected to harness 42,984.5 hectares.
