Lack of A Plan
Barrier number three is the lack of a plan.
This is where it all comes back down to design because design is the creation of a plan and permaculture is a design approach to arrive at solutions that have the diversity, stability, and resilience of natural ecosystems.
To design a system that is resilient (& sustainable!), the design must include redundancy and be efficient, productive, appropriate, and interconnected. In this excerpt, from our new book, Essential Rainwater Harvesting (New Society Publishers, 2018), we provide an an example of how to use these five simple words in the design of an offgrid homestead.
Resilient Systems & Properties
A system is a set of interacting or interdependent component parts forming a complex/intricate whole. The components that make up your rainwater supply are a system. The elements that are put together to provide for your shelter, water, waste and food needs can be thought of as a system, e.g. our homes are systems. Our neighbourhoods and our cities are also systems. Everywhere you look, systems are nested within systems and it’s really just a question of where you draw the boundary.
Resilience is the capacity for a system to adapt (and we would argue to continue to thrive) in the face of change or disruption. It’s an excellent compliment to sustainability, and arguably you can’t have resilience without sustainability. However, we like to present and think about systems in terms of their resilience because fundamentally, for many of our clients and students, their absolute primary motivation for taking action is to increase their personal resilience.
To expand on these resiliency characteristics, in the table below we present design choices and examples for each characteristic for a resilient property and contrast theses against design choices for most modest modern-day homes (i.e. a fragile property).
|CHARACTERISTIC||RESILIENT PROPERTY||MODERN DAY DESIGN|
|EFFICIENCY||Focus is on maximizing efficiency.
||Unlimited resource mentality.
|PRODUCTIVENESS||The home and occupants collect resources & produce abundantly.
||The home and occupants are merely consumers.
|APPROPRIATENESS||Energy and water appropriate for end use*.
||Energy and water not always appropriate for end use*.
|INTERCONNECTEDNESS||Design is cyclical and very connected.
||Design is linear and unconnected.
|REDUNDANCY||Redundancy is key
*Think of how inappropriate it is to cut butter with a chainsaw. The same idea applies to heating your home with natural gas, or using drinking quality water to flush a toilet. These are poor matches of energy density and water quality to end-use.
The property illustrated in the Figure shown below is an example of a resilient property located in a cold-climate. Note that you can apply the same resiliency characteristics to each individual sub-system for water, energy and food.
The Water Systems
- Efficient: All fixtures high efficiency/low volume, water re-use used to reduce irrigation and toilet flushing volumes. Gutters and roof designed to prevent rainwater losses. Water-wise landscaping.
- Productive: All water captured (building and landscape) and stored for use. Water employed to grow abundant biology.
- Appropriate: Highest quality filter located at drinking water tap. Greywater used for toilet flushing and irrigation. Rain used for irrigation.
- Interconnected: Wastewater is a resource and nutrients from wastewater are used to grow plants and soil both in the greenhouse and in the landscape. Monitoring in place for water usage, rain forecasts and storage volumes.
- Includes Redundancy: Water storage designed for appropriate low rainfall conditions. Back-up plan in place.
The Energy Systems
- Efficient: High insulation walls and windows and careful design of the building envelope. Energy efficient lighting and appliances.
- Productive: House orientated to capture passive solar energy. Careful design and selection of glazing. Attached greenhouse provides supplemental heating. Solar photovoltaics for electricity and solar thermal for hot water.
- Appropriate: Passive solar gain as primary heating source, biomass as back-up heating, photovoltaic electricity used for high energy density needs, solar thermal used for domestic hot water and ancillary space heat. Irrigation is provided passively (using gravity vs being pumped).
- Interconnected: Heat recovery ventilator use to pre-heat intake air. Warm stale air from the house cycled to the greenhouse. Excess heat energy from the greywater captured in greenhouse. Monitoring systems in place for energy production and storage.
- Includes Redundancy: Grid-tied power for back-up electricity. Heating provided by three sources: passive solar, active solar and biomass.
The Food Systems
- Efficient: Local food and seasonal food prioritized. Food grown onsite is harvested, preserved and stored for later use when in periods of abundance.
- Productive: Perennial forest gardening, annual vegetable production and four season production in the attached greenhouse. Micro-livestock systems (such as chickens) for eggs and meat. Biodiverse and abundant biology grown not only for the occupants but to support surrounding ecosystems.
- Appropriate: Food that supplies the occupants is grown with appropriate energy (human-scale vs large manufacturing-scale) and appropriate water (local & captured water vs imported water). Gardens designed for passive irrigation instead of pumped irrigation.
- Interconnected: Food scraps, plant and others wastes cycled to create compost, soil and/or to feed micro-livestock.
- Includes Redundancy: Not purely reliant on industrialized food system. Occupants grow some of their own food and support the local food economy as much as possible.
If your motivation is resilience, you’ll want to keep these characteristics in mind as you are designing your rainwater harvesting system, but also particularly as you consider your rainwater harvesting system in the context of full-property water security and overall property design.
Now don’t be intimidated by the scale at which we applied the principles of resilience, as you might not be ready to jump into designing fully offgrid homesteads. However, the beauty of using principles in design is that principles are universal, and can be applied at any scale. You can apply redundancy, efficiency, productiveness, appropriateness and interconnectedness to the design of a school garden, to be design of a food forest, or to the design of backyard composting system.
What we’ve found, over and over again, is that when folks regain hope, gain knowledge and learn how to plan / design they find more meaning and happiness in their life as well.
And so I’ll reiterate that humans are not inherently destructive. Simply start designing your sustainable future & meaningful life so that you (& your community) will thrive.
It’s time to start designing. Here are some suggestions:
- Read Part V, and Part VI of the the Permaculture Primer Notepack.
- Take one system in your life right now, preferably something simple. For instance it could be your front yard. Look at this system through the lens of redundancy, efficiency, appropriateness and interconnectedness. Are there simple actions you can take, or things you can change, elements you can add or elements you can remove that result in an improvement of these characteristics? Let me know what changes you make and the results that you get!
REALLY TAKE ACTION
How many times have you read good advice and not followed through? The truth is, the more complicated the challenge, the more we put it off.
If you want somebody to guide you through the process of creating a sustainable future & meaningful life, take action today.

Past Students Say…
If you ever thought that there had to be a better way of looking at the world, this course will not only offer one to you, but also give you the details on how to make it work. Life Changing!
Well worth the tuition fee. Learned so many options to use my life energy in a more sustainable way. Can’t wait to apply what I’ve learned!
If you’re interested in empowering yourself to build community and create a sustainable future for yourself and the world we live in, this is the PDC is for you. It’s inspiring and it’s skill building. I’m so excited to share what I’ve learned when I get home.
The sheer breadth and volume of content offered in the PDC made for incredible value. I feel like I now carry knowledge and perspective that are the seeds of true wisdom and a new confidence in the possibilities for living and working differently. Rob leaves you with no excuses for not becoming a positive force in the world!
