✍️ Sample PDC Questions & Answers

1. Which documentation practice BEST demonstrates regulatory compliance for PDC certified professionals?
Maintaining organized, dated, and signed records of all activities

Organized, dated, and signed records demonstrate systematic regulatory compliance.

2. In PDC design, what is the purpose of a 'stakeholder consultation' process?
To gather input from all people affected by a design so decisions reflect community needs

Stakeholder consultation ensures that those who will live with or be affected by a design are heard, increasing both the quality of the design and community ownership of outcomes.

3. What is the ethic of 'Fair Share' in permaculture?
Share surplus and limit consumption

Fair Share, also known as Return of Surplus, is the third core ethic of permaculture. It encourages individuals and communities to distribute any surplus resources or yields equitably and to limit their own consumption to what is truly needed. This ethic aims to ensure that everyone has access to resources and that the planet's capacity is not overexploited, promoting social and ecological justice.

4. How does permaculture design address conflict within intentional communities?
By establishing clear communication agreements, roles, and restorative processes before conflicts arise

Social permaculture designs proactive conflict resolution and communication systems (like nonviolent communication and regular community meetings) as infrastructure just as important as water systems.

5. In agroforestry, what does the term 'alley cropping' refer to?
Growing crops in rows between lines of trees or shrubs

Alley cropping places rows of trees or shrubs with crops grown in the alleys between them, benefiting from tree shade, leaf mulch, and root interactions.

6. Earthship buildings pioneered by architect Michael Reynolds are primarily characterized by which construction feature?
Used automobile tires rammed with earth as the primary structural wall element

Earthships use discarded automobile tires packed tightly with rammed earth as their primary structural wall, and often integrate rainwater catchment, greywater treatment, and food production systems.
