DECCMA and ESPA Deltas researcher Dr Alex Chapman’s piece “Climate change is triggering a migrant crisis in Vietnam” has just been published on The Conversation UK. The article outlines how net out-migration of one million people from the delta – over double the national average – relates to a reduction in agricultural productivity and the effects of repeated exposure to cyclones that cause erosion of land and infrastructure.
Crucially, the article highlights that the creation of embankments, intended by the government to support in situ adaptation, actually often have the opposite effect. This is because in protecting the land, the embankments prevent “normal” flooding that replenishes soil nutrients and supports fishery-based livelihoods. Dr Chapman concludes by highlighting the importance of ensuring economic growth and adaptation supports all groups of the population to reduce a potential migrant crisis.
