As climate changes causes seawater to flood land and increase the salt content in soil, farms in Scotland and the Netherlands are experimenting with using the saltwater to grow food.

And the Salt Farm Foundation has shown that potatoes, cabbage, and tomatoes can grow in saltwater. These projects can labor intensive, but seawater irrigation could be a viable climate adaptation solution.

In Kenya, like other countries in the world, deforestation is the major driver of tree cover loss.
