Vietnam province declares state of emergency over drought

A weeks-long heatwave has brought drought and saline intrusion to an area of Tien Giang Province, 60 km (37 miles) south of business hub Ho Chi Minh City.

The province's Tan Phu Dong area -- with 12 kilometers of coastline along the East Sea, crisscrossed by waterways -- has been particularly badly hit.

Salinization -- the intrusion of salt water from the sea -- has severely affected crops and thousands of households among the 44,000 people living in the area.

During this dry season, prolonged drought and deeper saline intrusion in the upper Tien river have surrounded communities with salty water.

The Mekong Delta faces saltwater intrusion every year, but more intense hot weather and rising sea levels -- both driven by climate change -- are increasing the risk.

Research published last month said Vietnam's Mekong delta, which provides food and livelihoods for tens of millions of people, faces nearly $3 billion a year in crop losses as more saltwater seeps into arable land.

Around 80,000 hectares of rice and fruit farms could be impacted by salinisation, according to the study from the Water Resources Science Institute under the environment ministry.

In 2016, which saw the worst drought in 100 years, 160,000 hectares of soil were impacted by salinization.
