The Qingtu Lake, suffered from drought for over 50 years, witnessed three square kilometers of water surface again after 8.6 million cubic meters of water from Shiyang River were infused into the lake by the end of October this year. Extensive farming since the 1950s sapped underground water in Minqin and destroyed the local ecology.
The 400-sq-km, 60-meter-deep Qingtu Lake dried up in the 30 years since the 1960s, and by the early 1990s, the lake had been smothered by creeping yellow sand. The newly revived lake plays a vital role in preventing desertification in Minqin County, which is one of China's three major sandstorm originations due to its lying between the two deserts of Tengger and Badain Jaran.
In north-west China, desert sands are swallowing up farmland and towns. Mingqin is a shrinking oasis area that government advisers privately describe as an "ecological disaster area", and yet eco-refugees have been resettled here because their home environments became no longer fit for habitation. Villagers must battle the encroaching desert that is destroying their homes and their crops
