Sietz A. Leeflang

From 1971 to 1977 Mr. Leeflang, as founder of the "Small Earth" project (De Kleine Aarde") in Holland, stimulated many to practice ways of life, agriculture and technical method that preserve the environment and are on a human scale.

In 1977 Mr. Leeflang and his wife left the project and started a small experimental centre for alternative techniques and working methods, called "The Twelve Trades" ("De Twaalf Ambachten"). In this centre several new techniques have been developed in the fields of water and energy saving, heating and house building.
