As the Syrian civil war enters its tenth year on March 15, the Signal Program on Human Security and Technology conducted satellite imagery analysis to capture the rapid expansion of displaced people’s camps and the widespread impact of aerial bombardment in Idlib, Syria. This work was completed in collaboration with Save the Children and World Vision International. On 1 March 2020, the UN estimated that 961,286 individuals have been displaced since December 1, 2019; this is the largest mass displacement and acute humanitarian crisis since the Syrian conflict began in 2012. Analyzing two internally displaced person (IDP) camps, the Signal team found that the camp areas analyzed increased by approximately 100% and 177% respectively between September 2017 and February 2020. Camp growth between December 2019 and 2020 revealed new structures and further construction, consistent with a significant influx of displaced persons. The UN Human Rights Council reports that between May 2019 and January 2020, aerial bombardment and a surge of ground-level assaults contributed to a wave of IDPs throughout Idlib as civilian areas were repeatedly targeted. Signal’s analysis of two areas in conflict-affected towns in southern Idlib found that approximately 30% of structures were damaged; this figure likely underestimates the total damage.
