Mekong delta, Vietnam’s rice bowl, is sinking
The delta is facing an existential crisis as rising sea levels, salinisation, and prolonged droughts threaten to alter the landscape irreversibly.

The Mekong delta in Vietnam is a world in itself, where water and earth intertwine in a primeval dance, creating a region of incredible fecundity and profound beauty, a testament not only to nature’s bounty but also its relentlessness. Yet, beneath this surface of life and abundance, the Mekong delta is on the front lines of a deadly battle against climate change and environmental degradation.
A paper published in Sustainability 1 in 2020 pointed out that rising sea levels and erratic rainfall are causing more frequent and intense floods, even in urban areas. And a study in Agricultural Water Management2 in 2020 showed that salt-water intrusion had gone deep into the inland paddy fields as a consequence of rising sea levels, while prolonged droughts were turning fertile fields into barren wastelands.
Salinisation, in fact, threatens the very foundation of rice cultivation in the delta, thus jeopardising the livelihoods of millions. Modern industry, meanwhile, intrudes with machinery and concrete, cash crops and pesticides, factories and huge dams, which further disrupts the delta’s delicate ecological balance.
The delta's future is further complicated by socio-economic changes. Urbanisation and industrialisation have increased the encroachments on agricultural land. Younger people are increasingly leaving rice cultivation and the delta for opportunities in the cities. The demographic shift is reducing the labour force available for rice farming, which is challenging the sustainability of traditional agricultural practices.
