Applying permaculture principle No 4;Obtain a yield - Bill Mollison says: "The yield of a system is theoretically unlimited (or only limited by the information and imagination of the designer)." So 'obtain a yield' is not something we do once, but is a design approach to how we farm, garden, run our homes and communities. Again, the possible number of uses of a resource within a system is mostly limited by the knowledge and imagination of the designer. You will see how this principle is similar, and different, to others concerning waste and energy.
Think of yields broadly. A yield does not have to be edible and does not even have to be tangible. Therefore, observing and recognizing potential yields is key. A chicken does not yield just eggs (and meat), but fertilizer and insulation, perhaps CO2 for plants, and even companionship, warmth, and love. Compost does not just yield fertile organic matter; it can also yield heat for a hot bed or a greenhouse
