Climate change poses new risks to human security and causes a
new context for migration (CARE, 2009). Sang and Long (2012)
showed that the largest source of migrants in Ho Chi Minh City
(HCMC) originates from Mekong Delta while (Dun, 2009)
demonstrated that environmental issues are important factors
promoting migration in this region. To further study the impact
of climate change on migration, the study aims at investigating a
correlation between the environmental impacts of climate change
and migration decisions. Based on 400 interviews with local
people in Ben Tre and Dong Thap provinces (highest sources of
immigrants in HCMC), statistical analysis (reliability analysis –
Cronbach’s alpha and factor analysis – EFA) proves that (1) the
impacts of climate change on production activities; (2) the
impacts of climate change on the quality of life; (3) the impacts
of climate change on environmental quality are factors which
have contributed to migration decisions of those suffering from
climate change. Correlation analysis results showed that there is a
correlation between the impacts of climate change and migration
decisions (p <0.05), and the decision to migrate directly
proportional to the increase in the influence of climate change.
