Satellite and Mobile Phone Data Reveal How Violence Affects Seasonal Migration in Afghanistan
Xiao Hui Tai, Suraj R. Nair, Shikhar Mehra, and Joshua E. Blumenstock

TL;DR
This study uses satellite imagery and mobile phone data to analyze how violence and conflict influence seasonal migration patterns in Afghanistan, revealing resilience to violence but sensitivity to long-term conflict dynamics.
Contribution
It introduces a novel approach combining satellite and mobile data to study migration in conflict zones, specifically assessing violence's impact on seasonal labor flows in Afghanistan.
Findings
High poppy cultivation districts attract more seasonal migrants.
Migration flows are resilient to violent events causing fatalities.
Long-term conflict patterns influence seasonal migration more than immediate violence.
Abstract
Seasonal migration plays a critical role in stabilizing rural economies and sustaining the livelihoods of agricultural households. Violence and civil conflict have long been thought to disrupt these labor flows, but this hypothesis has historically been hard to test given the lack of reliable data on migration in conflict zones. Focusing on Afghanistan in the 8-year period prior to the Taliban's takeover in 2021, we first demonstrate how satellite imagery can be used to infer the timing of the opium harvest, which employs a large number of seasonal workers in relatively well-paid jobs. We then use a dataset of nationwide mobile phone records to characterize the migration response to this harvest, and examine whether and how violence and civil conflict disrupt this migration. We find that, on average, districts with high levels of poppy cultivation receive significantly more seasonal…
