Holmgren's RetroSuburbia: Downshifting for a Resilient Future

In this interview, David Holmgren defines permaculture as a design system for sustainable living and land use, addressing both production from nature and consumption patterns from household organization to societal structures. He details his 12 permaculture design principles: observe and interact, catch and store energy, obtain a yield, self-regulation and accept feedback, use renewable resources, produce no waste, design from patterns to details, integrate rather than segregate, small and slow solutions, use and value diversity, use edges and value the marginal, and creatively use and respond to change. These form a framework for redesigning systems based on natural patterns, bridging abstract concepts to concrete solutions people demand. Applying to retrofitting, Holmgren discusses built environment changes like insulating houses, weatherstripping doors, installing solar panels, double glazing, and wood heaters for heating, water, and cooking to reduce electricity dependence. The conversation emphasizes permaculture's practical essence over theory, showing how principles translate to tangible retrofitting for energy descent. Holmgren highlights household-level actions as foundational for broader resilience, using RetroSuburbia to guide downshifting in everyday suburban life. Strategies focus on making homes fit new purposes amid declining energy availability, promoting yields from gardens, resource storage, and integrated systems that mimic nature's efficiency. This provides actionable insights for practitioners to implement permaculture in urban contexts, fostering self-reliance through specific retrofitting techniques and principle-driven design.
