Sustainable Ecosystem Basics

The idea behind permaculture is simple: take care of the earth, and the earth will take care of you.

Practical Permaculture: for Home Landscapes, Your Community, and the Whole Earth by Jessi Bloom and Dave Boehnlein introduces readers to permaculture, offering the tools needed to live a life rich in healthy food, safe housing, and renewable resources. Beyond providing tips for embracing permaculture design in personal gardens and community spaces, Bloom and Boehnlein answer some of the most-asked permaculture questions:

So, what is permaculture?  

Permaculture is the development of ecological systems that are sustainable and self-sufficient. 

In permaculture, design decisions are first based on ethics and then incorporate the logic of natural systems. Mimicking nature’s patterns makes our lives more sustainable and less reliant on resources outside of our control. In contrast to living in a wasteful, consumerist manner that depletes our resources and doesn’t leave future generations that much to work with, permaculture is about building resilience and using only what we need and what we have access to—in other words, living within our ecological means… 

In a nutshell, permaculture can be defined as meeting human needs through ecological and regenerative design” (Bloom and Boehnlein 11).  

Who first coined the term permaculture?  

Bill Mollison, an Australian biologist, educator, and author; and David Holmgren, an Australian environmental designer and educator, are credited with coming up with the term “permaculture.”  

“Permaculture is a term first coined by Bill Mollison and David Holmgren in the mid-1970s. It has been defined in a huge variety of ways, with the most common being a contraction of the words permanent and culture” (Bloom and Boehnlein 11). 

What are the principles of permaculture? 

Why is biodiversity important?  

Biodiversity is a backbone of permaculture, helping ecosystems stay healthy and resilient.  

“The diversity of species is usually an indication of ecosystem health. Natural ecosystems contain a wide variety of organisms—humans, plants, animals, fungi, bacteria, and so forth—that interact in the web of life. The more species within an ecosystem, the more potential for beneficial interaction.

Species may come and species may go. The same goes for individuals, but if there are many species and genetically different individual present, the whole system will not collapse with those changes. This means the ecosystem, on a whole, is more adaptable” (Bloom and Boehnlein 36).
