Building an Edible Floating Island
Aquaculture, Dams, Fish, Land, Plant Systems — by Erik Klockemann May 30, 2013
Here we are! We are underway with our Ten Week Internship with Geoff Lawton at the Permaculture Research Institute, Zaytuna Farm, in The Channon, New South Wales, Australia. We are a small group of only six interns, two teacher assistants and Mr. Geoff Lawton. The team has really formed a synergy and we feel great with some of the projects we have been able to complete.
Comments (24)Where Hope Flows
Conservation, Fish — by George Monbiot May 8, 2013
If the “hardest-worked river in the world” can recover to this extent, almost anything is possible.

Warning: this article begins with a spoiler. If you have not read The Road already and intend to do so, please skip the first three paragraphs.
Cormac McCarthy’s novel The Road, which I still believe is the greatest environmental work ever written, ends with the shock and beauty that runs through so much of the book:
Once there were brook trout in the streams in the mountains. You could see them standing in the amber current where the white edges of their fins wimpled softly in the flow. They smelled of moss in your hand. Polished and muscular and torsional. On their backs were vermiculate patterns that were maps of the world in its becoming. Maps and mazes. Of a thing which could not be put back. Not to be made right again. In the deep glens where they lived all things were older than man and they hummed of mystery.
The trout are a cipher for all that has gone, in this novel about a world that has lost its biosphere. I think I know why McCarthy chooses to invest them with this role: in a way that is hard to explain, trout seem to be more alive than most other animals. Perhaps it has something to do with their flickering changes of mood – extreme caution, then bold display, skulking in the shadows, then splashing on the surface of the river, sometimes leaping clear of the water – their great speed, their extraordinary beauty, their ability to disappear then flash back into sight, their remarkable range of colour and pattern and shape. And the presence of trout means that other things are alive: they cannot survive and breed without clean, clear water, clean gravel beds and an abundant supply of insect life.

Biodiversity, Consumerism, Economics, Fish, Food Shortages — by Earth Policy Institute February 4, 2013
by J. Matthew Roney, Earth Policy Institute
The fish near the bottom of the aquatic food chain are often overlooked, but they are vital to healthy oceans and estuaries. Collectively known as forage fish, these species—including sardines, anchovies, herrings, and shrimp-like crustaceans called krill—feed on plankton and become food themselves for larger fish, seabirds, and marine mammals. Historically, people have eaten many of these fish, too, of course. But as demand for animal protein has soared over the last half-century, more and more forage fish have been caught to feed livestock and farmed fish instead of being eaten by people directly. A growing body of scientific evidence suggests that current fishing levels are dangerously high—both for the forage fish themselves and for the predators and industries that depend on them.
Comments (1)Betting on Extinction
Biodiversity, Consumerism, Economics, Fish, Food Shortages — by George Monbiot
Ladbroke’s is offering odds on fish populations collapsing; the government is shortening them.
I’ve come across some odd ways to make a living, but few as strange as this. The gambling company Ladbrokes has been offering odds on the conservation status of various fish species. Until last night it was taking bets on mackerel; recently it has encouraged people to punt on the survival prospects of stocks of yellow fin tuna, swordfish and haddock. You can, if you wish, gamble on extinction.
It’ll be a while before I put my money on the recovery of any species in British waters.
Comments (2)Taking Stock: World Fish Catch Falls to 90 Million Tons in 2012
Biodiversity, Fish — by Earth Policy Institute November 21, 2012
by J. Matthew Roney, Earth Policy Institute
The U.N. Food and Agriculture Organization (FAO) projects that the world’s wild fish harvest will fall to 90 million tons in 2012, down 2 percent from 2011. This is close to 4 percent below the all-time peak haul of nearly 94 million tons in 1996. The wild fish catch per person has dropped even more dramatically, from 17 kilograms (37.5 pounds) per person at its height in 1988 to 13 kilograms in 2012—a 37-year low. While wild fish harvests have flattened out during this time, the output from fish farming has soared from 24 million tons in the mid-1990s to a projected 67 million tons in 2012.
Over the last several decades, as demand for fish and shellfish for food, feed, and other products rose dramatically, fishing operations have used increasingly sophisticated technologies—such as on-vessel refrigeration and processing facilities, spotter planes, and GPS satellites. Industrial fishing fleets initially targeted the northern hemisphere’s coastal fish stocks, then as stocks were depleted they expanded progressively southward on average close to one degree of latitude annually since 1950. The fastest expansion was during the 1980s and early 1990s. Thereafter, the only frontiers remaining were the high seas, the hard-to-reach waters near Antarctica and in the Arctic, and the depths of the oceans.

The "MEGGA-watt" Project (Micro-Energy Generating Garage Assembly) is a demonstration / prototype to turn everyday detached garages from simple storage units (aka ‘car-holes’) into food-growing and energy-generating systems using permaculture design.
The basic concept is to partner a garage with an attached greenhouse and renewable energy to create sustainable 4-season growing systems with minimal fossil fuel input that serves both practical and recreational purposes.
Owners of a MEGGA can then customize how they want the system to function — what they want to grow and how they want to grow it.

Biodiversity, Fish, Global Warming/Climate Change, Water Contaminaton & Loss — by Craig Mackintosh PRI Editor June 13, 2012
Take a fish’s eye view of the world. It’s both beautiful and fascinating. You’ll be peering under the waves to look at the least understood part of our world, the ocean and its hidden mysteries. In this video, you’re looking at the basis of your own existence….
Of course, not all is well in the plankton department. Climate change and its associated ocean acidification, along with widespread pollution, are threatening the building blocks of life….

The UK’s marine reserves offer no meaningful protection to the life of the sea.
by George Monbiot: journalist, author, academic and environmental and political activist, United Kingdom.
What do the terms “marine reserve” and “marine protected area” conjure up for you? Places in which, perhaps, wildlife is protected? In which the damaging activities permitted in other parts of the sea – such as trawling and dredging – are banned? Wrong.
A marine protected area in the United Kingdom is an area inside a line drawn on a map – and that’s about it. In most cases, the fishing industry can continue to rip up the seabed, overharvest the fish and shellfish, and cause all the other kinds of damage it is permitted to inflict in the rest of this country’s territorial waters. With three tiny exceptions, our marine reserves are nothing but paper parks.
Comments (0)A Small-scale, Traditional, Sustainable Way to Fish
Fish — by Claudette Fleming March 24, 2012
Indigenous peoples have employed various sustainable ways of obtaining food. Using a fish trap is just one of them.
The Kingfisher and indigenous people methods of fishing have one commonality — they are sustainable. No fish is wasted and there is always fish for tomorrow.
Traditional lowland indigenous peoples of South America most often fish daily and tend to fish only for the family and maybe other vulnerable members of the community, e.g. the elderly. Sometimes fish is preserved for future use, but fresh fish is always preferred. An advantage of daily fishing is that the catch is at its freshest. One important sustainable way to fish is to use a cell-type fish trap.
Comments (1)Urban Pool-to-Pond Conversion – Two-Year Progress Report

We’re writing on-going articles about the many aspects of this urban permaculture project in a Mediterranean climate, here in California, now two years underway. Today’s article: pool-to-pond conversion — complete!
My husband and I have been actively working on an urban 2/3 acre permaculture project for two years this month. We began the design and subsequent installation at a residence in October of 2009 and it continues in multiple phases today. As we complete the swimming pool to aquaculture pond conversion, and reflect upon our progress thus far, we would like to share our experiences — the trials, corrections and successes made along the way and to basically let more people know about this Mediterranean climate permaculture project.
Comments (10)A Look at Hawaiian Aquaculture – and How You Can Learn More About It at the Keawanui Fish Pond, Molokai
Aquaculture, Courses/Workshops, Fish, Land — by Nichole Ross October 6, 2011
It was a typical October day on Molokai — 82 degrees, sunny and breezy. I had just arrived at my favorite tiny airport on a nine-passenger Cessna turbo prop-plane from Honolulu. I came from the Big Island to help my Permaculture Research Institute (PRI) USA colleagues facilitate a Permaculture Design Course (PDC) already in progress. The PDC was part of a four-course series we were doing to train a local group made up of key players working to promote sustainability on the Island.
When my ride told me that the class would be starting the day at the Keawanui fish pond, I was both excited and nervous. Much like the time I had gotten an All-Access V.I.P. Guest Pass to the Red Hot Chili Peppers concert, I would soon be in the presence of celebrities I admired. I was not only about to meet the Rittes, but they were students in our PDC.
Comments (0)Mutually Assured Depletion
Biodiversity, Consumerism, Economics, Fish — by George Monbiot August 9, 2011
The EU, Norway, Iceland and the Faroes all blame each other for smashing the last great fish stock. All are wrong.
by George Monbiot: journalist, author, academic and environmental and political activist, United Kingdom.
Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a year, after which no one will ever eat fish again. Almost everywhere, fish stocks are collapsing through catastrophic mismanagement. But no one in the rich world has managed them as badly as the European Union.
So when the EU tells Iceland and the Faroes that they should engage in “responsible, modern fisheries management”(1), it’s like being lectured by Atilla the Hun on human rights. They could be forgiven for telling us to sod off until we’ve cleaned up our own mess. Unfortunately, this is just what they’ve done, with catastrophic results.

Have I just witnessed the beginning of the end of vertebrate ecology?
by George Monbiot: journalist, author, academic and environmental and political activist, United Kingdom
Last year I began to wonder, this year doubt is seeping away, to be replaced with a rising fear. Could they really have done it? Could the fishing industry have achieved the remarkable feat of destroying the last great stock?
Comments (14)Animal Systems at HEPA, Vietnam
Aid Projects, Animal Housing, Bird Life, Breeds, Community Projects, Demonstration Sites, Education Centres, Fencing, Fish, Livestock, Working Animals — by Marty Miller-Crispe May 19, 2011
At SPERI’s Human Ecology Project Area we have a number of Farmer Field Schools (HEPA FFS) which are host to students from a variety of indigenous minority groups from Vietnam and Laos. The students are here to learn about eco-farming and permaculture whilst respecting traditional laws and customs.
The main focus of the farms isn’t to be productive, but rather to provide an environment where the students can experiment with various farming methods of growing crops and raising animals. So, although we do obtain a yield from the farms, the greater yield is the knowledge the students gain from trial and error.
HEPA FFS is in lush rainforest near the Laos border south-west of Ha Noi. The weather here varies from very cold winters (no snow but feels like it could!), to hot dry summers toasted with hot winds from Laos, and moving into cold monsoons and flooding at other times of the year. As such it is a challenge for the students to obtain a yield from the crops year round, and even more of a challenge to keep healthy animals.
Comments (7)Sea Water Farming
Aquaculture, Community Projects, Fish, Food Plants - Annual, Food Plants - Perennial, Land, Plant Systems — by Oyvind Holmstad March 30, 2011
The two videos below are much about scaling up mangrove systems for sustainable sea water farming, done in a true permaculture spirit from which both people and nature benefit. Sadly this is in stark contrast to industrial aquaculture, where they throw cheap energy on unsustainable systems to maximize profit.
Today mangroves are disappearing fast. Thirty-five percent of mangrove ecosystems disappeared between 1980 and 2000, according to the Millennium Ecosystem Assessment. Shrimp farms have been a primary cause of mangrove loss, as well as urbanization and agriculture. This is why the message from The Seawater Foundation is of such an importance, as they show how to change and provide hope for the future.
