Radar interferometry offers new insights into threats to the Angkor site

A groundbreaking study leverages radar interferometry to uncover critical threats facing the Angkor site, offering new insights that could inform sustainable conservation strategies for other UNESCO World Heritage Sites. By analyzing subtle ground deformations over time, researchers identified patterns of subsidence and structural instability, which are not easily detectable through conventional methods. This approach provides a more precise understanding of environmental and anthropogenic pressures affecting the site, such as groundwater extraction and urban development. The findings underscore the importance of integrating advanced remote sensing techniques into conservation planning to mitigate risks and ensure long-term preservation.
