Is landsmanship an Aussie term? It sounds like what we call stewardship in the states. Also, it looks like it all goes to one guy.

I came across the linked pdf when I was looking up Natural Sequence Farming by Peter Andrews which was/is an alternative agricultural method invented in Australia in the 70's.
Peter Andrews has a couple of well-known videos by "Australian Story", a documentary show on the ABC (a government subsidised broadcaster). It's probably worth a post of its own: https://www.youtube.com/watch?v=-4OBcRHX1Bc
All the links go to one guy cause I threw them in at the end for education purposes and to expand the reading for anyone that wanted to follow up, the linked pdf was written by both of them. I assume the term was coined by them, I've never heard it used in conversation. Stewardship is of the same ilk, except that would be a far more popular and well-known word.
