12. Connecting the Dots with
Permaculture
Permaculture is an ecological design system
for sustainability in all aspects of human
endeavor
www.permaculture.org
Permacultural systems tend toward creation
of forest ecosystems that sustain humans
in a multiplicity of ways
13. Principles to look at
1) Design elements are put in the right place
2) Each element serves many functions
3) Each function is served by many elements
4) Put often-managed elements near the house
5) Put rarely-managed elements farther away
6) Pay attention to sun, wind, and fire directions
7) Stack plants vertically
8) Use time stacking
14. Primary Tenets
1)Earth Care – Earth as home – it's the only one we
have
2)People Care – Helping each other in a way that
develops healthy societies
3)Fair Share – Limit consumption so that others
have their share
