PDC Design & Implementation Strategies 3 — Questions and Answers
Question 1: A permaculture designer uses a scale model of a site during client consultations. This tool primarily serves to:
- Replace the need for site visits
- Help clients visualize spatial relationships and design decisions (Correct answer)
- Calculate precise water volumes for earthworks
- Determine soil chemistry requirements
Correct answer: Help clients visualize spatial relationships and design decisions
Physical or digital models help clients and designers visualize how elements relate spatially, improving communication and design accuracy.
Question 2: What is 'guilds' in the context of permaculture design implementation?
- Organizations of certified permaculture designers
- Legal cooperative structures for land ownership
- Groups of plants that mutually support each other's growth and productivity (Correct answer)
- Layers of the forest garden hierarchy
Correct answer: Groups of plants that mutually support each other's growth and productivity
A guild is an assemblage of plants (and sometimes animals) selected because their combined interactions create a more productive and resilient system than any plant alone.
Question 3: When implementing water harvesting on a slope, which earthwork is designed to slow, spread, and sink water along the contour?
- Keyline channel
- French drain
- Swale (Correct answer)
- Bermed berm
Correct answer: Swale
Swales are on-contour ditches that intercept runoff, allow it to spread horizontally, and infiltrate into the soil rather than flowing downhill.
Question 4: In permaculture, the 'problem is the solution' approach encourages designers to:
- Ignore site challenges and work around them
- See existing site problems as resources or opportunities (Correct answer)
- Document problems for future designers to solve
- Report site problems to local authorities
Correct answer: See existing site problems as resources or opportunities
Reframing problems as solutions means that a wet boggy area, for example, can be embraced as a water feature or wetland habitat rather than a drainage problem.
Question 5: Which of the following best describes a 'sector' in permaculture design?
- A zone determined by distance from the house
- An area of the site with uniform soil type
- An external energy or influence that passes through the site, such as sun, wind, or fire risk (Correct answer)
- A division of the site for different family members
Correct answer: An external energy or influence that passes through the site, such as sun, wind, or fire risk
Sectors map external energies — sun angles, prevailing winds, flood paths, fire risk — that enter the site and must be managed or utilized by the design.
Question 6: A designer is creating a market garden and wants to maximize edge between different crop areas to increase biodiversity and yield. Which design shape best achieves this?
- Long rectangular strips of uniform width
- Circular beds with no pathways
- Curved or crenellated bed edges with integrated pathways (Correct answer)
- A single large square bed
Correct answer: Curved or crenellated bed edges with integrated pathways
Curved and crenellated edges increase the total length of the boundary between different areas, creating more microhabitats and interaction zones.
Question 7: What is the role of 'pattern understanding' in the permaculture design process?
- Applying nature's repeating forms and patterns to design efficient, productive systems (Correct answer)
- Following standardized templates from permaculture textbooks
- Replicating patterns observed in tropical ecosystems globally
- Using geometric shapes for aesthetic garden design
Correct answer: Applying nature's repeating forms and patterns to design efficient, productive systems
Pattern understanding involves recognizing recurring forms in nature — branching, spirals, waves — and applying these to design efficient structures and relationships.
