Could an app help protect Vietnam’s paddy fields?

Vietnam is one of the biggest producers and exporters of rice in the world, but the livelihood of some farmers is under threat.

Seawater intrusion has long been a problem in the low-lying Mekong Delta, where more than half of the country’s rice is grown. During the dry season, the salty water can leach into fields and ruin crops. It’s thought rising sea levels are exacerbating the problem.

The International Fund for Agricultural Development (IFAD) and the government of Vietnam have launched a smartphone app, which monitors the saltiness of the water. The data helps rice farmers decide when to flush out the paddy fields with freshwater to protect their crops.
