There are two basic steps to good permaculture design. The first deals with laws and principles, while the second is more closely associated with practical techniques.
The principles are inherent in any permaculture design, in any climate, and at any scale. They are, briefly:
Relative location: every element is placed in relationship to another so that they assist each other
Each element performs many functions.
Each important function is supported by many elements.
Efficient energy planning for house and settlement.
Emphasis on the use of biological resources over fossil fuel resources.
Energy recycling on site.
Using and accelerating natural plant succession to establish favourable sites and soils.
Polyculture and diversity of beneficial species for a productive, interactive system.
Of all the principles of software engineering which has fallen by the wayside in the modern “move fast and break things” mentality of assholes modern software developers, reliability is perhaps the most neglected, along with its cousin, robustness. Almost all software that users encounter in $CURRENTYEAR is straight-up broken, and often badly.
It is not evident, though many people, from the early Greeks on, implicitly act as if it were true, that all things, whatsoever they may be, can be put into words—you could talk about anything: the gods, truth, beauty, and justice. But if you consider what happens in a music concert, then it is obvious that what is transmitted to the audience cannot be put into words—if it could, then the composer and musicians would probably have used words. All the music critics to the contrary, what music communicates cannot (apparently) be put into words. Similarly, but to a lesser extent, for painting. Poetry is a curious field where words are used but the true content of the poem is not in the words!
