Satellite data shows major cities around the world are experiencing significant land subsidence.

The gradual sinking of ground levels can severely damage buildings and infrastructure, exacerbating flood risks. This issue is compounded by limited information on subsidence dynamics, making it challenging for policymakers to pinpoint areas needing urgent intervention. Previous assessments have varied in methodology and scope, hindering comprehensive global comparisons.

This land subsidence not only damages structures but also increases the likelihood of flooding, affecting millions of residents.

Without accurate data and consistent monitoring, long-term vulnerability to flooding and infrastructure damage will continue to rise.

Can local infrastructure withstand future compounding shocks?

The lack of standardized subsidence data hampers effective planning. Cities must invest in continuous monitoring systems to assess risks accurately. Immediate action is needed to prevent further degradation and potential collapse of critical infrastructure.

Immediate steps are necessary to avoid catastrophic failures.
