    Mr. Fang is now the owner of 36 greenhouses producing organic vegetables in the Gobi desert in Northwest China’s Gansu province. He is one of the beneficiaries of the Gobi Farming Program of Gansu province that is building rows of greenhouses in the desert to help transform local farming and alleviate poverty.

Grain production in Gansu is greatly affected by the climate and the output is unstable. Agricultural production there relies heavily on rivers, oases and groundwater irrigation. If traditional extensive agricultural production continued, it could gradually narrow the living space.

In 1995, a local entrepreneur ventured to use Israeli technologies to build greenhouses for vegetables growing in the desert. Such individual pilot projects encouraged the Gansu government to launch a provincial-level Gobi farming program in 2017 with a target to build up a controlled-environment agriculture of about 20,000 hectares by 2022. Some cities in the province, which include Fang’s village, have already been experimenting with Gobi farming for several years.

Despite the harsh environment, farming in the Gobi desert has its advantages: the extended amount of sunlight provides adequate energy for crops, a significant temperature difference between day and night helps crops accumulate nutrients and the Gobi’s hot and dry air means fewer pests and crop diseases. The Gobi greenhouses popping up in Gansu use drip and spray irrigation, which can cut water consumption by almost 50 percent compared to a normal farm. The greenhouses are also eco-friendly, as they use substrates for soilless cultivation recycled from rotten leaves, straw and cow and sheep feces.

With the greenhouses, Fang earns around 70,000 yuan annually. Data from Suzhou. district of Jiuquan showed the greenhouse program has helped bring an average revenue of about $ 72,300 per hectare to local farmers. Large scale greenhouse farming is an investment-intensive project and cannot be sustained only by government financial support. Therefore, the local government has been encouraging villagers such as Fang to take the lead to rent greenhouses or build their own.

It is not an easy task, and many villagers still want to wait and see. However, more and more are starting to join in,either to rum their own greenhouses or work as hired workers for greenhouse owners. Starting from managing four greenhouses in 2009, Fang now is also a partner of a greenhouse farming cooperative running 120 greenhouses.

The relatively low cost of large-scale land use in the Gobi desert have also encouraged large firms to start their Gobi farming pilot projects in Gansu. If the Gobi farming proves successful, it could provide experiences for countries in Central Asia linked with Gansu both by the ancient Silk Road as well as its modern version of the Belt and Road Initiative.
