Climate change and impacts in Viet Nam

Viet Nam is considered as one of the most vulnerable countries due to CC and sea level rise. If sea level rise of 1 m, Viet Nam will loose about 12% of land, 23% of population will be affected. Typhoons occur more frequently with higher intensity. Temperature increases and change in rainfall pattern will affect agriculture and water resources.

This is the largest percentage of 2m 4m impacted population among all 84 countries. Vietnam impacted population would 1m reach 35% with a 5m SLR.
