Researchers suggest repurposing old mine shafts for climate-resilient farming
A team in Shanxi has proposed using abandoned coal mine tunnels for underground agriculture, citing insulation from surface weather and disasters. An estimated 15,000 mines in China are expected to close by 2030, and existing infrastructure like power grids and ventilation could be repurposed. The scientists argue that closed-environment farming offers stability as climate change threatens traditional agriculture.
The proposal originates from a research center in Shanxi, a key coal-producing region. Their findings appeared in a specialized mining journal. The concept leverages the existing infrastructure of these sites—such as power lines, ventilation, and water sources—to create controlled agricultural environments.
With roughly 15,000 mines slated for closure by 2030, the researchers evaluated the feasibility of essential growth factors like light, temperature, and water within these subterranean spaces. They argue that the inherent insulation from surface weather events makes such closed systems a viable response to climate-related agricultural instability.
This concept could offer a new economic lifeline for coal-dependent regions facing mine closures, potentially preserving local jobs in engineering and maintenance. For broader society, it may contribute to food security by providing a stable supply of produce unaffected by extreme weather. However, the high energy demands for artificial lighting and the logistical complexity of underground operations could limit its scalability, meaning it may serve as a niche supplement rather than a mainstream agricultural solution.
