Scale of Permanence
How does the Scale of Permanence categorize elements in permaculture design based on their level of changeability?
There are three categories that elements of a design can fall into; those changeable, those that should remain unchanged, and those unchangeable. Scale of Permanence prioritizes the most permanent elements of a design. We are guided to observe the elements of a site starting with the larger, more permanent elements, then narrow down to the finer detail elements from there which will be the least time and resource consuming to change.
Why is understanding the permanence of climate, topography, and water flow crucial in permaculture design?
These are the Immutable (unchangeable) elements in any design. By observing and understanding these elements first, they can guide our decisions on the less permanent features ensuring a holistic, resilient design. For example, when building a livable structure on site understanding these elements first will guide us in choosing the structures most appropriate materials, location, layout, ect.
How do immutable elements like topography and climate influence the overall design decisions for a site?
By observing and understanding these elements first, they can guide our decisions on the less permanent features ensuring a holistic, resilient design.
Discuss an example of a semi-permanent element and how it impacts design decisions.
There is the structure of a cabin on my site I plan to finish renovating. Because I intend to keep as much of the existing structure as possible, I will have to design the elements of the cabin in a way that compliments the existing layout while also incorporating elements that connect the cabin to the rest of my design as harmoniously as possible.
How can the Scale of Permanence guide the selection and placement of plant species in a permaculture design?
First, gain an understanding of the immutable elements of a site, like climate and natural water flow. Allow these observations to guide plant selection and placement. This ensures that the plants you select to grow will have the greatest chance of surviving and thriving with minimal outside input.
Share an example of how recognizing permanent infrastructure elements influences water management strategies.
The barn is a permanent structure on my site. It has a large roof and is in an elevated position from the future garden site. I can harvest the watershed from the roof and channel the overflow down the steep hillside towards the garden site.
How does the Scale of Permanence contribute to resource allocation and efficient resource use in a design?
Scale of permanence encourages us to allocate the most permanent resources to the most permanent elements, and less permanent resources to less permanent elements.
How might the permanence of soil structure affect your choice of plants and their location in a garden?
My site is located on land the was strip mined years ago. The soil structure varies from one area to another. In some areas the soil is very dry/rocky while other areas of soil are easily waterlogged and there’s a section of soil that’s almost completely clay. By understanding the permanence of soil composition compared to that of the plants, the time and resource investment would be significantly less by placing plants in the soil that is most suited to them vs trying to adjust the soil to best suite the plants.
In what ways does the Scale of Permanence promote biodiversity enhancement in a permaculture design?
Scale of permanence guides us to observe our site from the most to least permanent elements that make up our site. With climate, typography, and natural water flow being among the immutable elements of a site they will dictate what plants will and will not thrive there. This guides us to selecting more native plants, leading to more biodiversity in our garden designs.
How does considering the permanence of climate and environmental conditions help in creating resilient permaculture designs that can adapt to changing circumstances?
By considering how nature is in a permanent state of change over time, including environmental conditions, we can design our site to be able to withstand future changes as well. By observing and researching the environmental conditions of a site overtime we can make educated guesses as to where the changes will lead and design our site in a way to mitigate future predicted environmental patterns.
