Climate change is projected to convert existing risks in the region into severe key risks . Key risks are assessed as follows: 1. Risk of food insecurity due to droughts; 2. Risk to people and infrastructure due to floods and landslides; 3. Risk of water insecurity due to declining snow cover, shrinking glaciers and rainfall variability; 4. Risk of increasing epidemics, particularly of vector-borne diseases; 5. Cascading risks surpassing public service systems; 6. Risk of large-scale changes and biome shifts in the Amazon; 7. Risks to coral reef ecosystems; and 8. Risks to coastal socioecological systems due to sea level rise , storm surges and coastal erosion.
