1.7 Million Vietnamese Have Left The Mekong Delta In 10 Yrs; Rising Oceans Killing Rice Fields
Global sea level rise caused by fossil fuel burning is an issue that is creating worsening impacts to cities, nations, and civilization itself. And according to recent reports out of Vietnam, 1.7 million people have migrated from the low-lying Mekong Delta region over the past decade. Primary causes included climate change and poverty.
EDIT
Rising oceans have forced Vietnam to erect a system of dykes of up to 4 meters in height in an increasingly complex system of coastal defense barriers. These barriers have saved lands from inundation as the ocean off the low-lying Mekong Delta continues to rise year-after-year. However, the dykes have not prevented salt water from moving further and further up the Mekong River. And during recent years, this salt water has inundated soils used for rice production.
Such salt water inundation has wiped out crops for many farmers. For example, in the Soc Trang region, the farmers of Thang Dong saw their crops completely wiped out during 2013 as salt water seeped into the soil and killed off food-producing plants. In low-lying near coastal regions, the story has been much the same for Mekong farmers. And with less reliable crops come increasing poverty.

When crop production is no longer tenable due to climate change impacts, many farming families have been forced to move on. A majority cite poverty as the root cause. But 14.5 percent are more aware — noting that climate change was what ultimately forced them to leave.
