About Permaculture Design: an ethical approach to earth care and people care

Permaculture Design is a field of ecological design, drawing lessons from natural systems and utilizing the latest “green technologies” to create sustainable and regenerative systems.

Permaculture encompasses many aspects of our lives: how we generate and use energy, build our buildings and landscapes, grow or obtain our food, use water, manage resources and how we impact the earth’s ecosystems.

Permaculture principles provide a framework to inform the design process.  Some of these principles include energy efficient planning, integrated systems design, small scale intensive systems, use of biological resources, use of appropriate technology, and planning systems that care for people and the earth.
