Watch Bombuj. This project started with video from a three day workshop. The workshop covered the earthworks for building a pond without a liner, a swale, and a hugelkultur bed on a terrace. Then we added more footage by doing the same workshop over again in a colder climate. A year later, we returned to the first workshop site and added even more footage! We even had an evaluation by the Crown Prince of Permaculture, Geoff Lawton.
