This was only in a small part of Spain, mostly turistic. Those places full of english expatriates are always overrepresented in english newspapers IMHO, giving a false impression. It can seem worst that it is also. Free water means literally free money fallen from the sky and of course those big companies have enough muscle and resources to replace the plastic greenhouses and restart quickly.

The winter was not particularly hard. I remember a bad couple of weeks. Not much more. A little chill is good for most fruits.

Casually, I has aubergines for dining today. It seems that the problem to find spanish vegetables in the market is solved.

Vegetables don't just magically appear in minutes - they take weeks or months to grow, so bad winter has an effect which can last for most of the year.
