Integrating multilingualism and permaculture/farming

My two passions are the land and languages. I'm currently studying Mandarin, Spanish, Taiwanese, and German. I am pretty comfortable with my Mandarin and Spanish, i just started Taiwanese and German within the last month though. Learning language is definitely what I know the most about, and spend most of my time doing. Any suggestions on combining languages and permaculture into some way for me to contribute to people? Many of the languages on my hit list are used in third world countries.
