Here's a basic description on the site of a permaculture center managed by Cooperativa Las Cañadas in Huatusco, Veracruz, México:

The Spanish videos on this page might also help;

Wikipedia Spanish page on permacultura:

Principios de Permacultura en Español:

Also, you could do a Google search on permacultura (which is how I found the Wikipedia site

):
https://www.google.com/search?q=permacultura&nirf=permaculture&sa=X&ved=0ahUKEwj9t8GLoYfWAhWI8YMKHZuqBZYQ8BYIJigB&biw=1920&bih=929. If you're regional settings are for English, Google will try to be helpful and search for permaculture instead. However, you should have a link to "force" it to permacultura. I think the link I gave will already be "forced" to permacultura.
I don't speak much Spanish, but I knew about the Las Cañadas food forest and Google translate let me at least check that the basic information was what I was looking for.
