Recent geopolitical upheaval in Syria is driving regional growth by returning populations, which increases demands on water resources. In northwest Syria, widespread cropland abandonment during the Syrian War starting in 2011 drastically changed the hydrological regime of the region. Here, we show how this situation, which constitutes an uncoordinated, large‐scale "reverse pump test", has resulted in regional groundwater recovery. River discharge has increased, springs have re‐emerged, and regions are now episodically uplifting up to 4 cm/year in wet years. By combining conflict event databases and remote sensing techniques, including Interferometric Synthetic Aperture Radar, we identify a strong correlation between conflict‐induced cropland abandonment and land surface uplift, indicating spatially‐variable groundwater recovery. Conversely, in areas where groundwater abstraction persisted, subsidence has continued unabated. As ground‐based data are nearly non‐existent in war‐afflicted Syria, this remote sensing‐based approach enables a unique assessment of water storage dynamics and reveals the risk of unsustainable groundwater exploitation in the future. Plain Language Summary: The war in Syria damaged much of the country's irrigation systems and forced many farmers to leave their lands, thus considerably decreasing groundwater irrigation. Using satellite data, we found that this sudden drop in water use allowed groundwater levels to recover, causing the land to rise—up to 4 cm/year in wet years. Rivers are flowing stronger, and springs have reappeared. However, in areas where pumping continued, the land is still subsiding. These findings show how conflict can unexpectedly influence water resources and highlight the risk of future overuse once groundwater irrigation resumes. Key Points: War‐driven cropland abandonment in Syria caused a large‐scale "reverse pump test," revealing widespread groundwater recoveryInterferometric Synthetic Aperture Radar shows episodic land uplift up to 4 cm/yr linked to cropland abandonment in wet yearsPersistent pumping areas still subside, warning of future groundwater stress [ABSTRACT FROM AUTHOR] |
