Subsidence areas can be turned into farmlands

Since food security plays an important role in China's social stability and development, the government has implemented a strict arable land protection policy, which includes improving land quality, balancing the use and replenishment of arable land, securing grain production, and enforcing accountability for arable land protection.
Transforming land that has subsided due to mining into water-surface farmland will contribute to not only food production but also environmental protection. Mining produces minerals and creates employment and wealth, but it also generates pollution and causes land subsidence.
In China, coal reserves and arable land largely overlap. Land subsidence in coal mining areas is usually deep and wide, and it usually takes a long time for such land to stop sinking and become stable.
