In Fuyuan County, Yunnan, a groundbreaking initiative is turning thousands of acres of dormant winter fields into productive potato farmland, boosting farmer incomes and enhancing regional food security. This pilot project demonstrates how technological support and market-driven crop selection can unlock the vast potential of underutilized arable land.
The project, spearheaded by the Fuyuan County Agriculture and Rural Affairs Bureau, targets over 10,000 acres of prime farmland along the Jia River basin in Housuo Town. Traditionally, after the autumn harvest, these fields lay fallow throughout the winter due to climate conditions and customary practices. Launched as a pilot in 2023, the program focuses on cultivating suitable winter crops, primarily potatoes and fava beans. Key to its success is the selection of the popular “Laomila” potato variety, prized for its soft, fluffy texture and flavor. Under the hands-on guidance of county agronomists, farmers have adopted an integrated technology package featuring mulch drip irrigation, integrated water and fertilizer management, and green pest control. As agronomist Zhang Benqiang noted, after two to three years of refinement, this tailored set of practices has successfully increased the land’s multiple cropping index.
This local success aligns with a major national priority. The Chinese government has consistently emphasized increasing the utilization rate of arable land and boosting the multiple cropping index as critical strategies for food security. According to a 2023 report from the Ministry of Agriculture and Rural Affairs, initiatives to develop “winter idle fields” are actively promoted across southern regions to increase grain and vegetable output. The Fuyuan model exemplifies this policy in action. By creating a high-value winter crop that meets market demand—with plans for green food certification—the project ensures economic viability. This market pull, combined with scientific push, has transformed “sleeping fields” into “golden fields.” The local Haoyun Farmer Cooperative, having seen excellent market reception, has expanded its planting area, demonstrating the model’s scalability and farmer confidence.
The Fuyuan County winter potato initiative is a compelling case study in sustainable agricultural intensification. It successfully addresses the dual challenge of low land-use efficiency and the need for farmer income growth. By combining targeted agronomic research, the extension of integrated technologies like drip irrigation, and a focus on market-preferred varieties, the project has created a replicable blueprint. For agricultural professionals globally, it underscores a vital principle: enhancing productivity isn’t always about claiming new land; it can be about innovatively and scientifically unlocking the full potential of existing farmland, turning seasonal downtime into a period of growth and prosperity.
