"The purpose of Keyline tech-niques and the keyline scale ofpermanence in relation to cli-mate is the take completeadvantage of all weatherand climatic phases thatwill enhance soil climatethrough maintenance in the soilof improved relationships be-tween the factors of moisture,warmth, and air , and, by con-trast, minimise to the fullthe disadvantages of thoseclimatic elements that de-stroy , namely, flood rains,drought and fire."

“The most significant aspect ofthis analysis is that it involvesa pattern, a recognition thatsmaller shapes are integratedto form a larger whole, and thatthis pattern might be repeatedseveral times on a singlemedium-sized property.”

Before and After KeylinePlough Intervention

Before

● deeply biologically degraded

● climatic forces destructive/ degenerative

After

● the beginning of regenerativeprocesses

● water and sun movefrom destructive toconstructive processes / forces

Earthworks - Storage for People / Stock

24 / 27

● controlled water distribution

● put water through its ’duties’
