The Iberian peninsula is slowly but surely desertifying. Part of it is due to climate change, sure, but it doesn’t help that governments aren’t willing to pass and enforce regulations against the mass cultivation of plants that require huge amounts of water, such as avocados, in regions that do not naturally receive as much rain. If we keep stupidly trying to use more water than we need and the local ecosystems can afford, it’s only logical sooner or later we’d have these issues with olives, amongst many other troubles.
