Welcome, Arturo!
I don't know of any zoning system for other parts of the world. I don't think much of the USDA system, myself, and rarely use it. We do have Sunset Western Garden zone maps that cover the western states, and is far more useful. They have many more zones that describe the effects the topography has on our weather like ocean influence, desert winds, mountains, basins, etc. It has large zone maps and you can look up your zone, then read up on that zone. Check it out on line. I live in zone 22 (the Los Angeles basin), in southern California for instance. It could concievably be adapted to other countries if one wanted to take the time. l tried, but couldn't get a link. Go to sunset.com if interested.
