SDG 13: Climate Action

  • Water resources are threatened by climate change and population growth
  • Scottish startup Seawater Solutions is helping the country's farmers grow salt-resistant plants using seawater
  • Plants like samphire and sea blite are growing in popularity

A British startup is teaching farmers how to grow crops using water from a source which won’t run out – the sea.

Seawater Solutions is helping farmers on Scotland’s west coast adapt to the reality of less rain by choosing salt-resistant plants and developing saltmarshes - land flooded by tidal waters - for them to grow in.

“These plants can create eco-systems and promote wildlife, but they can also feed us in a sustainable way and return health to the soil,” said Seawater Solutions founder Yanik Nyberg, as he planted sea aster – a flavoursome, wild plant.

The company is working with Jay Crawford, a potato and carrot farmer, to farm an acre of his land previously underused because of its exposure to the sea wind and salt spray.

“We’ve taken a piece of land here that was maybe only going to yield a couple of hundred pounds per year into something that could maybe yield a couple of thousand pounds per year,” he said.

Pipelines running from the sea bring water that recreates the tide and irrigates crops of bright green samphire stalks and sea blite, a herb-like plant that looks like rosemary, as well as aster.

Typically used as gourmet garnishes, the plants are becoming more mainstream and demand is growing by 10% per year, according to Seawater Solutions.

George Chubb of Glasgow greengrocer Roots and Fruits said the plants were really popular because of their “extreme taste” and “eco credentials”.

Growing populations, intensive farming and climate change are putting pressure on the world’s limited water supplies, researchers say. United Nations data shows two billion people – a quarter of the world’s population – are now using water much faster than natural sources can be replenished.
