WhatisPermaculture?
• OriginatedinAustraliainmid1970s.
• DevelopedbyBillMollisonandDavidHolmgrenaroundideasofstableagriculture.
• “PermacultureOne”publishedin1978.
• Permaculturecombinesthreekeyaspects:
• 1.anethicalframework.
• 2.understandingsofhownatureworks.
• 3.adesignapproach.

CareofEarth

• Workswithnaturalsystems,ratheragainstthem.
• Usesmethodsthathaveminimalnega1veimpactontheEarth’snaturalenvironment.
• Designingandcrea1nghealthysystemsthatmeetourneedswithoutdamagingtheplanet.
CareofPeople
