The Takeaway
Exposure to a specific type of mountain flood causes permanent damage to a child's life path. These events in High Mountain Asia result in significantly lower body mass index for survivors once they reach adulthood. The trauma and economic loss from a single day of flooding create a physical and intellectual scar. We often view climate disasters as temporary setbacks that communities eventually overcome. This data proves that the effects of a flood follow a person for decades. A child's potential is physically altered by the environment long after the water recedes.
From the abstract
This study examines the long-term impact of childhood exposure to Glacier Lake Outburst Floods (GLOFs) on adult human capital in High Mountain Asia. Using historical GLOF data and geospatial mapping, we identify treatment and control groups based on geographic proximity. Exposed children attain 1.4–1.7 fewer years of schooling and have 1.9–2.2 kg/m2 lower adultBMI. Rural adolescents face greater educational losses, whereas urban residents experience more pronounced health impacts. Our findings hi
