There is some evidence of an association between climate-related rural-to-urban migration and the risk of civil unrest . Petrova  found that while migration in general was associated with increased protests in urban receiving areas, the relationship did not hold for hazard-related migration. In other settings, the association of civil unrest with in-migration was found to depend on the political alignment of the host state with the capital , previous experience of extreme climate hazards  and previous experience of violence among migrants . Climate-related migrants have reported higher levels of perception and experience of violence in their destination . There has been no association established between international migration and conflict. The literature highlights how unjust racial logics may generate spurious links between climate migration and security .
