Assessing the impacts of climate changeon population fluctuations in Ho Chi Minh City

Abstract

Climate change affects the economy, society, life, and human health. However, the effects of climate change are expected to vary by country and locality. The article clarifies the impacts of climate change on population fluctuations in Ho Chi Minh city based on climate change and population development scenarios. The results of the climate vulnerability assessments show that: (i) Climate change is negatively related to the human development index (HDI); (ii) Rainfall exposure index and population growth rate have a positive relationship; (iii) A statistically significant association was found between climate vulnerability index and sex ratio at birth; (iv) The effects of climate change on population distribution will be not obvious in the near future (year of 2030), but will be more visible in the distant future (to 2050) with high climate change scenario; (v) The influence tends to increase gradually from the old inner city to the new inner city which is highest in the sub-urban area. Therefore, recommendations are proposed to mitigate the impacts of climate change on population fluctuations in Ho Chi Minh city.
