Food security has many facets. It is easy to see that we are generally over-dependant on food shipped in from all over the earth (grapes from South America in January; apples from New Zealand in July; dates from Iran and almost any kind of food from California). It is also easy to see that this makes us vulnerable to supply line disruption and extreme weather events in other places.

At the same time, having access to an incredibly diverse range of fresh and preserved foods at all times is one of the great luxuries of the modern industrial world. We are fortunate indeed to be able to buy the ingredients for a Greek Salad in February or pull a bag of frozen strawberries out of the freezer at any time of year.

We are now living in a world that will likely have more and more unusual weather events and where we must consciously reduce the amount of fossil fuels we burn. Simultaneously, more and more people are discovering the delicious and healthy reality of fresh-picked produce and the satisfaction of having nurtured their food from seed to table.

I am certainly not suggesting that we should stop shopping at supermarkets and only live on potatoes and kale grown in our back yards, although you are welcome to give it a try. What I advocate is becoming more aware of the history of our food (like Barbara Kingsolver documents in her terrific book Animal, Vegetable, Miracle). By becoming more intimately involved with where our food comes from, we gain an appreciation for the miraculous life-support network that we are all a part of.

It radically changes your view of food to shift from buying a sealed plastic bag of identical thumb-sized orange cylinders off the shelf at a supermarket, to pulling your first carrots of the year out of the damp earth, putting the green tops back in the compost, and immediately crunching on the roots.

Growing our own food, even just a few tomato plants, helps us share with growers around the world the uncertainties of pests and weather, and the joys of abundant harvest after days or weeks of patient waiting. If you grow fruit trees, it may even be a few years before your care and attention are rewarded with a sweet harvest. Planting trees and gardens is an exercise in optimism. Many perennial food plants take a long time to reach full production, but will continue to provide food for generations.

To pursue food security involves some insecurity. There is a chance that the crop will fail and then you won’t get to eat those delicious foods you were anticipating. (Thank goodness there’s still a supermarket to fall back on!) On the other hand, there is an equally good chance that the crop will be so abundant that you will have to study food preservation techniques or risk losing some friends due to an embarrassing need to give away excessive amounts of fresh produce.

Nature may be “red in tooth and claw” where carnivores are concerned, but it is also red in berry and fruit, and green in leaf and stem. Once you start growing food, you may never stop!

Here is the Biodome Revolution: Reloaded geodesic greenhouse test lab. Using our revolutionary hub system I built the above greenhouse three years ago and have been testing all kinds of things since then.

If you would like to learn more simply sign up for the Biodome Revolution Webinar using this link: Biodome Revolution Webinar: How to Become Food Secure, Make Money and Help Make a Better Planet

In the webinar my friend Kacper and I cover off a ton of amazing content including:

  • How to design and build your own geodesic greenhouse
  • What to watch for when dealing with nosy building inspectors
  • How to become food secure during these uncertain times
  • Using your Biodome Greenhouse to make money (without growing veggies)
  • Why having a backyard food factory is the best insurance policy you can get
  • What top scientists are not telling us about the impact of global climate change
  • and a ton more.

Geodesic Cabin Concept

Geodesic Cabin Concept

I just had to share this idea that I just got from Elliander in a comment.

“Thinking further ahead though: The world’s largest Geodesic domes are, if I recall correctly, in Singapore and measure 38 meters tall from ground level. They use water as the primary temperature control mechanism, but I would be very curious to see what would happen if you had a giant dome like that that also goes as deep as it goes tall. Imagine, for example, a mile wide dome set into the side of a mountain. If you used waterfalls on the perimeter and had the water go down a bit below ground level that would help as an energy store drawing the heat of the into the water while reflecting light back at the plants for better illumination and would also act as a cold sink. The total area would be just under 22 and a half acres and you would have a height of around 250 feet. The waterfalls would help catalyze cloud formation and it would be tall enough for the tallest trees in the world to thrive. You could easily have entrances to housing between waterfall segments and at that far down there would be no heating or cooling issues. Variations in day length could be adjusted for with LED lighting in the dome itself powered by wind systems. How cool would it be to have a tropical forest anywhere you could find wind and sun? (italics mine)”

The whole idea of a geodesic cabin combo got me so excited I whipped one up!

Here it is please let me know what you think and share comments.cabin_dome

The crafty Swedes have done this even more aggressively by wrapping the whole house in a greenhouse. Cuts heating costs by 50% and gives way more flex space. I thought the geodesic biodome backyard had more punch though!

Walipini or Geodesic Biodome Greenhouse?

Walipini or Geodesic Biodome Greenhouse?

Normally I focus on geodesic greenhouses but this old-yet-new design caught my eye recently. Its got a weird name but it works and its cheap to build too. Its know as the Walipini and it utilizes natural forces to provide  warmth, light and protection for year-round vegetable growing. Location, location location. In real estate and when building a greenhouse, even one 6’- 8’ underground, location is essential. Then capturing and storing daytime solar radiation as heat and plant growth comes next.


A Walipini, is a rectangle shaped hole cut into the ground (hire a backhoe!) then covered by greenhouse plastic. The long face of the rectangle aims to the winter sun while a thick wall of rammed earth at the back of the building soaks up any available solar gain. Then a much lower wall at the front provides the needed angle for supporting the plastic roof of the greenhouse. This roof seals the greenhouse, provides an insulating airspace, and allows the sun to create a warm, stable environment for plant growth.

Because the Walipini is an earth sheltered building it uses the thermal mass of the and seasonal temperature lag of the earth to keep the indoor climate stable, thus much less energy is needed to heat up the earth sheltered greenhouse vs. an above ground one. Of course, one must take care with waterproofing, drainage and ventilation, as well as solar alignment, just as you would when building any kind of greenhouse.

Best of all, a 20ft x 60ft can be build for a total cost of around $300, if you use free or your own labor of course! Cheap but effective, the Walipini underground greenhouse is a great way for growers to produce food all year round.

But, if you have high water table, are on bedrock, just love domes and or don’t have soil suitable for earth sheltered building, go with the biodome greenhouse. But if you have less money and lots of friends who like to dig, then the Walipini might be a great option!
