Dutch scientists have found a method for growing certain crops on salinized, non-arable farmland. This is truly an innovation, since food production on salinized soil has always been considered impossible. It was discovered that specific varieties of potatoes, carrots, red onions, white cabbage and broccoli actually thrive when irrigated in a special way, with salt water at the roots.
Salinization worldwide problem
Salinization is a worldwide problem, affecting approximately one billion hectares of farmland. In the Netherlands, around 125.000 hectares will be salinized in 2030, due to rising sea levels, land subsidence and dry summers, which cause a shortage of fresh water. As a result, salinity increases and farmland is rendered useless. Worldwide attempts have been made to halt this threat to food production, for instance by crop improvement and desalinizing land. So far, these attempts have been unsuccessful.
