We all know the old saying: “give a man a fish, you feed him for a day. teach a man to fish, you feed him for a lifetime.” But what happens when the corporations take that one step too far, fishing the oceans and rivers to near extinction? And what does any of it have to do with gardening?
Two things, actually. The first, is that the big fishing question is just one more component of a much larger food security coin that growing our own food at home can help to address. The second, is the growing movement known as aquaponics.
Aquaponics is basically a hybrid of aquaculture and hydroponics, comprised of fish tanks and garden troughs. The waste from the fish fertilizes the plants. The plants purify the water for the fish. And because it all happens in a closed, water-conserving system, aquaponics is especially interesting for low-rain areas such as our high-desert. I hope to be learning and posting a lot more about aquaponics in the near future, but in the mean time, check out these videos from two companies dedicated to growing aquaponic culture, Friendly Aquaponics in Hawaii and Colorado Aquaponics in Denver.
The bulk of the work focuses on ancient gardening techniques and includes an entire section of methods of taro farming which I found myself longing to try, if only Northern California had the right climate. Ironically, another section of the book discusses what the author considers the top ten most nutritious vegetables, most of which he was sad to say he couldn’t grow because they required much cooler and less humid conditions, which made it the perfect list of what to grow in my garden.
It’s true that most everything in there is pretty basic, and that the author, who’s from the mainland, may not be the most immediately or obviously credible source of old Hawaiian knowledge and lore (gardening or otherwise). Still, he brings a joy and reverence to his topic that both charms and enlightens. And the appendices include pages of sobering statistics, inspirational quotes, footnotes galore, a glossary of terms, and, most importantly, a list of references and resources including the University of Hawaii’s Tropical Agriculture program.
