The production is at risk because everything is manual and not very profitable anymore for the small local producers.
In Puglia, to have fresh tomatoes when it is not the season we prepare the so called Pendola tomatoes. In the summer we pick the tomatoes with the vine. We hang the tomatoes with the vine on a rope and store them in a cool environment. The skin turns hard but the juice stays inside! Then in the winter, we simply roast them: the skin breaks down and the tomatoes release all the juice and the taste of the sun!
Do you have any other way to suggest to preserve vegetables and tomatoes?
