Just farming in sunny places is also expensive and complicated. It's also vulnerable to drought, flooding, frost damage, pests, blockades, tailbacks at ports etc. I'm lucky enough to live in one of the most food secure countries in the world, but not everyone is in the same position. There's value in having a food source near big population centres.
