We investigated if radar data from the Sentinel-1 satellite can be used to assess displacements in permafrost areas in the Swiss alps. We discovered that 92 % of the permafrost areas can be visible with Sentinel-1. Next, based on displacement times series derived from radar data we revealed that the ground movements in permafrost areas are 2–3 times as large than in permafrost without areas. This result can help in monitoring permafrost areas and update current permafrost maps.

Ongoing subsidence is a complex problem for the Netherlands. Old strategies for coping have limits. In the Dutch National Scientific Research Program on Land Subsidence (2020–2025), we will develop an integrative approach to achieve feasible, legitimate and sustainable solutions for managing the negative societal effects of land subsidence, connecting fundamental research on subsidence processes to socio-economic impact of subsidence and to governance and legal framework design.
