China takes stock of groundwater resources for first time
China's total storage of groundwater resources stands at about 52.1 trillion cubic meters, the China Geological Survey announced on Thursday.
The country's total storage of underground freshwater is about 37.4 trillion cubic meters, and underground saltwater is about 14.7 trillion cubic meters.
China's groundwater storage increased by 36.3 billion cubic meters in 2021, noted the China Geological Survey, including a net increase of 35.7 billion cubic meters of shallow groundwater storage and a net increase of 600 million cubic meters of deep groundwater storage, compared with the previous year.
In 2021, the China Geological Survey organized 25 surveys with the help of 31 provincial-level geological environment monitoring agencies to complete the first national groundwater storage evaluation.
