*5.4.4 Population movement*

Climate change by creating unsuitable living conditions (e.g., desertification, sea-level rise, decline in freshwater availability, food shortage, health issues) will move many people (forced displacement, planned resettlement, migration). Poor communities are particularly impacted by the human movement. It is estimated that by 2050, up to several hundred million persons will be moved (**Figure 18**) [32]. Population movement will expose countries to multiple challenges (e.g., social, health, and financial consequences and violent conflicts).
