    Abstract Subsidence, the lowering of Earth’s land surface, is a widespread and sometimes dramatic process. Potentially 19% of the global population is at high risk of being affected by this process (1). Such sinking is caused by a range of natural or anthropogenic factors, including human-induced underground fluid withdrawal, which is generally considered the most important driver. However, present understanding of subsidence is fragmented and qualitative, including measurements, attribution to drivers, prognosis, and appropriate responses. On page 301 of this issue, Ao et al. (2) report using a radar technique called interferometric synthetic aperture radar (InSAR) to map consistent large-scale measurements of vertical land motion across all the major urban areas of China. Its successful application to quantify subsidence points the way to a systematic approach for assessing its causes as well as potential responses in real time and in the future.
