Are there different regional or international practices in permaculture that folks need to understand?
Every region has its unique culture, and unique needs and resources. So yes, there are differences. There is a lot of cultural diversity within many regions as well. I say,"Vive le difference!"
Let's embrace the diversity, and welcome it as something that is healthy for the system, rather than resisting it. What do we really need to agree on? I would say that we need to agree to use what works, not what doesn't, and to keep observing to make sure we notice when it's not working. Beyond that? Let's discuss!
