Build a Banana Circle
A banana-paw paw circle is an excellent way to grow fine fruit and root vegetable crops whilst using up excess water and organic wastes.
by Jan Buckley
Why it works so well
The design is basically a circular swale, and it works well because there’s only one place to mulch, feed and water, which serves many plants. It’s a good spot to put all your kitchen scraps, to use as a handy compost heap, and it can also take cardboard, paper and tin cans. It can make use of excess water run-off, or if water is scarce, greywater can be directed to the circle so water is reused.
On top of that, bananas grow well in a circle, and bear bunches on the outside. Both bananas and paw paws are gross feeders and thrive on nutrients from the decaying organic matter in the central hole.
So you get ample production of fruit, and root crops. You can also plant climbing plants like beans to grow up the banana stalks once they are tall. Volunteer plants like pumpkins and tomatoes are likely to spring up from vegetable scraps in the compost.
Harvesting Water DVD released
Harvesting Water the Permaculture Way
Geoff Lawton’s new permaculture DVD Harvesting Water is selling well after a few weeks delay in January because of the foreign language subtitles that producer Frank Gapinski was waiting to incorporate into the DVD.
The excavator and the forest
Last training camp we were fortunate in having an excavator in operation on the farm. Earthworks were a go and water harvesting / tree growing systems were carved out harmonically into the landscape. Three new swale systems and a small dam were introduced, extending the productive edges on the farm.

First big rain at SouthWoods
Following up on Testing the Dam in SouthWoods in Minnesota, here’s a series of pics showing how the new swales handled a decent storm.
Testing the dam
Following on from yesterday’s post on dams and swales in Minnesota, here are some pics of the system in action with the addition of the most important element: water.

Dams and swales in Minnesota
Hi folks! — we have been busy digging up Minnesota with dams and swales. This is just the beginning of the “Permaculture Research Institute for Cold Climates”. We’re now on route to California, hopefully to do some more serious digging. 
Here’s how we started:

Backyard Aquaponics
This just in, from Christopher Nesbitt:
“Backyard Aquaponics” is a new book by Joel Malcolm, an innovator in Perth, Australia and is well worth a look.
Aquaponics is a very simple and efficient system involving aquaculture and hydroponics. The system is dependent on plants in grow beds, generally pea gravel, being used to filter out fish manure and other material while aerating the water to maintain oxygen levels.
Joel’s book is substantial, with plenty of information and is broken down into several chapters, spread out over 113 pages of text, photos, graphs and diagrams. In it he does a good job in pulling the reader into the wonderful world of aquaponics by creating a seductive and idyllic picture of the productive system in his backyard.
Use of permaculture under salinity and drought conditions
Jordan is an arid country with limited water resources. The available renewable fresh water resources dropped drastically to an annual per capita share of 155 m3 in recent years compared to 3400 m3/cap/year in 1946. It is considered also as one of the 10 poorest countries worldwide in water resources (Countries with less than 500 m3/capita/year are regarded as having “absolute scarcity”).
In 2004, the total water use in Jordan was 866 million cubic meters (MCM) at the total population of about 5 million people. The total renewable resources in Jordan is estimated at 780 MCM include ground water at 275 MCM/year and surface water at 505 MCM/year of which only 70% is of economic use. An additional 143 MCM/year is estimated to be available from fossil aquifers. Brackish aquifers are not yet fully explored but at least 25 MCM/year is expected to be accessible for urban uses after desalination.
The demand on water use has been increased with increasing the socioeconomic development in the country. Agriculture consumes the major parts of water resources of about 62.5% of the available resources, domestic use consumes about 32.5% while industry about 4.3% and rural uses is 0.8% of the available water resources.
Ground-based action funding
Due to an inspiring collaboration between Rainforest Information Centre and Permaculture Research Institute teaching a permaculture design certificate course in Australia, a surplus profit of $AUS1, 500 we have been able to direct towards permaculture extension in Jordan. The same amount was also directed to a Rainforest Information Centre in Ecuador.

Water in the Mexican landscape
Water gives life and can also destroy life.
When we allow rain water to flow gently over the landscape taking the most time making the most contact with earth water is most fertile. But, when running uncontrolled it can cause erosion and death. No food can grow on land which is eroded and farming can only flourish on fertile soil. But only eco-systemic farming systems can create soil.
At ITT we believe in eco-systemic production systems which allow interactive diversity to develop and to become stable and fertile. To achieve it, we must create a great number of useful connections between the diverse elements on our land.
Two weeks ago we initiated the development of our training centre in permaculture here in the dry tropics. On our site in the municipality of Ejutla, Oaxaca, Mexico, we get approximately 800 milimeters of rain per year. Before the rain gods open the water gates, we invited the water harvesting an earth works specialist Geoff Lawton from the Permaculture Research Institute in Australia to assist us in the construction of an efficient rain catchment and water administration system. Geoff an expert consultant in water harvesting and management with great earth dam and swale building experience in over 17 countries.
These are the basic principles our experts recommend:
