In the mountainous areas of western Hubei, where the Yangtze and Qingjiang rivers converge, and deep within the misty peaks of the Wuling Mountains in Chongqing, the term 'Youyou Grass' is evolving from local slang into a digital calling card. It is not the name of a specific medicinal herb, but a general term used by farmers in both Hubei and Chongqing for a wild herbaceous plant—one that thrives in poor soil, grows quickly, was once burned as firewood, and has now become a sought-after commodity on big data platforms.
Earlier this year, the 'Youyou Grass Industry Big Data Project,' jointly initiated by the agricultural and rural departments of Hubei and Chongqing, was quietly launched. The project team has set up over 200 monitoring points across eight counties and cities, including Enshi, Yichang, Wanzhou, and Qianjiang. Using satellite remote sensing and IoT sensors, they are collecting real-time data on Youyou Grass's distribution density, growth cycles, soil moisture, and market circulation. This marks the first-ever full-chain digital survey of such a non-staple agricultural product in China.
'Previously, we relied on the experience of veteran farmers to decide where to harvest and where not to. Now, it's all clear on the screen,' said the head of a cooperative in Lichuan City, Enshi Prefecture, pointing to a data display. On the screen, a heat map indicates the reserves of wild Youyou Grass, with darker colors representing higher density. Beside it, real-time price inquiries from traditional Chinese medicine markets and bio-extraction companies scroll by.
Behind this 'data breakthrough' lies a long-standing industrial dilemma for both Hubei and Chongqing: Youyou Grass is rich in flavonoids, making it a high-quality source of natural antioxidants, but it has long been harvested in a 'scattered, chaotic, and small-scale' manner from the wild. Due to a lack of precise origin information and quality standards, buyers压低 prices, and farmers engage in blind harvesting, leading to resource waste and ecological damage.
The intervention of big data is changing the rules of the game. In Wanzhou, Chongqing, a biotechnology company successfully screened three high-quality seed sources by analyzing historical meteorological data and soil samples, using algorithms to predict the optimal transplantation window. The company's head revealed that the effective compound content in Youyou Grass from the 200 mu (approx. 13.3 hectares) of standardized pilot fields planted this year is over 30% higher than that of wild individuals. 'Data tells us where to plant, what to plant, and how to manage—no more guesswork.'
An even more profound change is occurring on the distribution side. A WeChat mini-program called 'Youyou Grass Hubei-Chongqing' has been launched. Farmers can upload photos and GPS coordinates of their collection points. The system automatically identifies the variety and provides a reference purchase price. If the data is verified via blockchain, they can also receive a 'Digital Origin Certificate,' allowing them to sell at a premium of 5% to 10% in transactions.
However, challenges remain. During field visits, reporters found that network coverage in some remote mountainous areas is still weak, and elderly farmers have low acceptance of smart devices. Furthermore, the boundaries of data-sharing rights and responsibilities have not been fully clarified—what data constitutes public resources, what involves trade secrets, and how to unify data standards between Hubei and Chongqing all require more detailed institutional design.
'Youyou Grass may be small, but behind it lies the livelihoods of hundreds of thousands of farmers and the ecological red lines along the border of two provinces,' said a researcher from the Hubei Academy of Agricultural Sciences, who leads the project. 'Big data is not a panacea, but at least it gives us the capability for "precision strikes" for the first time.'
Currently, Hubei and Chongqing have jointly released the 'Youyou Grass Industry Big Data White Paper,' planning to complete a comprehensive resource survey across the entire region by the end of the year and open some data interfaces to research institutions and small-to-medium-sized enterprises. A data-driven battle for an ecological industry breakthrough is quietly unfolding amid the mountains and fields.
