PDC Principles & Ethics of Permaculture 4 â Questions and Answers
Question 1: Mollison's principle 'Work with nature, not against it' is most directly violated by which practice?
- Sheet mulching to suppress weeds
- Tilling soil annually to control compaction (Correct answer)
- Using companion planting to deter pests
- Designing swales along contour to slow water
Correct answer: Tilling soil annually to control compaction
Annual tillage disrupts soil structure, destroys fungal networks, and accelerates oxidation of organic matterâworking against natural soil-building processes.
Question 2: The principle 'Make the least change for the greatest possible effect' emphasizes which design quality?
- Complexity
- Elegance and leverage (Correct answer)
- Speed of implementation
- Maximum output volume
Correct answer: Elegance and leverage
Elegant design identifies keystone interventionsâlike a single swale that rehydrates an entire hillsideâthat produce outsized positive results with minimal disturbance.
Question 3: Which design strategy best reflects Holmgren's principle 'Integrate rather than segregate'?
- Growing fruit trees in one zone and vegetables in another to simplify management
- Combining chickens, fruit trees, and annual beds so each benefits the others (Correct answer)
- Separating water catchment areas from planting zones to prevent flooding
- Using monocultures to streamline harvest logistics
Correct answer: Combining chickens, fruit trees, and annual beds so each benefits the others
Integration means placing elements so their relationships are mutually beneficial, such as chickens fertilizing the orchard while controlling pests beneath fruit trees.
Question 4: According to permaculture ethics, the concept of 'yield' extends beyond food production to include which other types of output?
- Only marketable commodities that generate income
- Information, energy, community, and ecological services (Correct answer)
- Raw materials harvested for manufacturing
- Tax-deductible agricultural expenses
Correct answer: Information, energy, community, and ecological services
Permaculture yield includes any surplus that can be reinvested into the system, such as saved seeds, knowledge gained, community bonds formed, or ecosystem services generated.
Question 5: The phrase 'The yield of a system is theoretically unlimited' was coined by Mollison to convey which idea?
- There is no physical limit to how much food a farm can produce
- The only limit on a system's output is the designer's imagination and knowledge (Correct answer)
- Industrial inputs can infinitely scale any agricultural operation
- Permaculture sites never need rest or fallowing
Correct answer: The only limit on a system's output is the designer's imagination and knowledge
Mollison meant that creative, observant designers who work with natural processes can always find new yieldsâinformation, energy, biodiversityâbeyond obvious material outputs.
Question 6: Which of the following actions most violates the permaculture ethic of Earth Care?
- Harvesting rainwater from rooftops for garden irrigation
- Draining and developing a wetland to create agricultural land (Correct answer)
- Planting a diverse hedgerow along a field boundary
- Composting kitchen scraps to build soil fertility
Correct answer: Draining and developing a wetland to create agricultural land
Wetlands are critical ecosystems providing water filtration, flood control, and biodiversity habitat; draining them destroys these irreplaceable services.
Question 7: Holmgren's principle 'Observe and interact' recommends spending at least how long observing a site before major interventions?
- One week in each season
- One full year through all seasons (Correct answer)
- Three months during the growing season
- One month before planting begins
Correct answer: One full year through all seasons
A full year of observation captures seasonal water flow, sun angles, frost pockets, wind patterns, and existing biodiversity that shorter observation periods would miss.
