Only one more sleep before the course is over…

Today there was excited buzz in the air, and it seemed like the group was slightly less focused on the lecture. The reason, I am guessing, is this afternoon’s session when we got to present our designs to the group. Many (most) of the people haven’t done a group assignment since school days, let alone stand up and talk about it. The pressure was on.

If this wasn’t enough, today is the last full day of the course, and it is set to conclude with a party at which everyone will have to present a talent, otherwise we don’t get our PC certificate! All of a sudden, the classroom and the lunch break were enlivened with people sitting in circles and sketching to prepare for their presentations. Music instruments made an appearance, women spinning Hoola Hoops on the lawn, didgeridoo and guitars. It was great! So cheerful, energetic and…very human.

The morning lecture discussed the risks of bush fires and how to survive them. If you are designing for a region with dry hot spells (like Melbourne region, for example), you will need to have a plan for bush fire shelter.

Design Research

This is a photo of the paddock we are working with. As you can see, it’s mostly an open field sheltered by the surrounding buildings and a tiny amount of slope.

land maps, research, surrounding structures

We did some homework and found an aerial view of the property on Google Maps and a campus map, which accurately outlines the surrounding structures.

Equipped with these tools, we set to work.

Group Dynamics

We set outside at the highest point of the paddock with a blackboard and a box of chalk, trying to fit in all the elements, but it was obvious that our design process was not very efficient…too many drivers and not enough focus…

9 Comments on DAY 9: Community Finances or How To Never Pay Income Tax Again (PDC 2010 with Bill Mollison and Geoff Lawton)

Today Bill and Geoff shared information about what may be the main questions we all have. How do we fund all these wonderful ideas we’ve learned. How do we navigate community and government structures; how do we organize people for action. It was not a topic we expected from a Permaculture course, but it’s a very important one. It stirred up questions and lengthy discussions, skeptical gazes and hopeful eyes.

Community Finances

There are two types of community economies: formal economy and informal economy.

Water Duties

Water has to perform 3 main duties before it runs off to the sea. If rain water lands (of flows) straight into the river and is carried out to the sea, it hasn’t performed its duties, and thus it hasn’t been most beneficial to the Earth and its inhabitants.

Pro-create life (human included)
Aquaculture
Energy (deliver and carry out)

It is to our benefit and benefit of the system to re-cycle water was mush as possible before allowing it to leave the system.

House sewage water can be completely cleaned up and become suitable for putting back into house by using a long trench filled with gravel and Typha reeds. The roots of the reeds have little trap doors that catch any organisms that pass next to them and digest them. Typhas can even take out E. coli bacteria to safe levels.

Water Arithmetics

97% of all water on Earth is salt water
of remaining 3%:
- 14% is deep ground water (below 800ft) – this is fossil water that took thousands of years to travel from the surface. It cannot be renewed in our lifetime, and it can only be accessed using heavy-duty pumps. This is the water that modern monoculture farming is sucking up…
- 11% is shallow ground water (less than 800ft deep)
- 74% trapped in snow and ice caps
- ONE PERCENT is lakes/ponds, forests, living systems, soils, rivers and atmosphere
There is a constant amount of water in the Earth system. Like energy, it doesn’t come from anywhere and it doesn’t go anywhere; it only changes its position and state. Hence, the water in my body right now could’ve in a dinosaur at some stage :).
