Permaculture Design for Slope

CORRECTION: There is an error in this diagram. The 30% slope section is drawn too gently. That section should be drawn slightly steeper then the 25% slope section, but it is instead drawn more gently than that section. The corrected drawing would show that the slope that Mollison recommends for permanent forest is steeper than what is drawn.
CLARIFICATION:
The way that the percentage of slope is represented in this video is different from conventional civil engineering. Civil engineers represent the percentage of slope as simple rise / run, so a 100% slope is 45 degrees. In the Permaculture Designer's Manual, Bill Mollison represents slope like it is shown in this video. We are not sure where Moillison's method of representing slope percentage is derived from, but it differs from the engineering representation.
Designing for slope in a permaculture system is a key aspect for being in beneficial relationships with water, soil, warm and cold air flows, forests, gardens, and the appropriate placement of all elements. This video is an animated summary of much of the information on slope provided by Bill Mollison in the 'Permaculture Designer's Manual'. This presentation is by Andrew Millison and is part of Oregon State University's Permaculture Design Certificate Course.

    I'm in Colorado at 7000 feet where it's dry as a desert at times. Took almost 10 years to dig my well, but last fall I finally got water flowing. It goes from my well up about 150 feet so it gravity feeds everything below it. I'm working on my degree in permaculture design myself, and my land project is my masters piece. Thanks for this refresher, my BM PDC book disappeared 25 years ago.

    This is fantastic for understanding good use of a LARGE area. But since I don't own a hill/forrest and the valley below it (I mean, let's be honest, only a tiny fraction of the population does), I'm having a hard time extrapolating this down to MY size (1/4 to 1/2 acre slightly sloped plot in Italy). I REALLY like your explanation and the drawings and genius presentation method, but could you direct me to a video that does the same thing but for a small plot of land? So....instead of the uphill "forest" there is the blackberry/small trees/bushes uphill boundary against the steep terrace wall coming down from adjacent property, then our narrow terrace with Olive trees.

    Oh, weird. Apparently, Mollison's mathematical definition of %slope is different from everyone else's. I (an engineer-like person) just thought that rise:run = 3 :10 = 3/10 = 30%. So, 1:2 = 50% and 1:1 = 100% and 2:1 = 200%. The steepness of the lines drawn was perfectly fine, but someone needs to ask Bill Mollison what numbers he uses.

Going to try to make lemonade out of a lemon and collect all that incoming water in a cistern.

    From one Andrew to another, thank you for putting together a fantastic course. A question or two if I may - could I understand why there is such concentrated focus on Mollison's work? I'm guessing permaculture is too broad for Mollison to have been the originator of much of his work? I also get the sense that Masanobu Fukuoka, e.g. 'one straw revolution' has been at least somewhat overlooked in the west. What's your view?

  • @amillison

    @amillison

    3 жыл бұрын

    Mollison and David Holmgren originated the word "Permaculture", and he wrote the "Permaculture Designers Manual", so Mollison really laid out the permaculture design system as a land assessment and design protocol more than any others. Fukuoka is more of a philosopher. He had a method, but it was not as clearly spelled out and universally applicable as what Mollison laid out. Another person who clearly laid out a design system that serves a lot as foundational material for permaculture is P.A.Yeomans with the Keyline Plan.
