Natural building,
compost, swales, hugel, and finding land seem to be biggies. I am a newbie, but i would like to see a separation between food forests and forest farming - agroforestry. Thats it.
Oh oh. Edit. Every gathering and convergence i go to has NO idea how to approach financial aspects of starting or substaining and income from permaculture. I realize there is no soild answer, but it is a huge question and never goes further than just a few income stream ideas. Most permaculutists that i know, who dont have a second job, only teach.
