Land subsidence severely threatens most of the coastal plains around the world where high productive industrial and agricultural activities and urban centers are concentrated. Coastal subsidence damages infrastructures and exacerbates the effect of the sea‐level rise at regional scale. Although it is a well‐known process, there is still much more to be improved on the monitoring, mapping and modeling of ground movements, as well as the understanding of controlling mechanisms.   

The International Geoscience Programme approved the project IGCP 663 “Impact, Mechanism, Monitoring of Land Subsidence in Coastal cities (IM2LSC)” aiming to bring together worldwide researchers to share expertise on subsidence processes typically occurring in coastal areas and cities. IGCP 663 plans to research the impacts of human activities and sea-level rise, hydro-mechanism and monitoring methods of land subsidence in coastlands with special focus on coastal cities of the less developed countries in Asia, Africa and Latin America.
