I just watched an episode of a show called Jose Andres in Spain on Max. Famous chef Jose Andres and his daughters go around to different Spanish cities/regions sampling food and wines.
The episode I watched was on Lanzarote, which is not very green, covered in volcanic ash.
However, they managed to grow all kinds of produce and of course harvest a lot from the sea.
They grow a blanc wine from green grapes which are watered only by condensation at night.
But instead of planting traditional rows of vineyards, they have these circular stone or brick structures around each vine.
