an integrative design science for sustainable human communities


Permaculture Design allows us to integrate all the complexities involved in sustainability; Water, energy, construction, primary production, spatial planning, land management, resource management, pest control, waste management, nature conservation and all the other elements that raise issues for our survival, and our need to achieve true sustainability.
