Update on Permaculture Pygmies – Introducing Solar Ovens, Water Filter and SODIS
Aid Projects, Biological Cleaning, Community Projects, Energy Systems, Potable Water — by Xavier Fux February 1, 2012
We built a solar oven made out of cardboard, and showed the pygmies how to purify water through a solar disinfection unit (the SODIS System). We also showed them how to make a filter with a bucket full of sand, gravel and active carbon.

Who said last days weren’t productive? Before leaving, we wanted to provide the pygmies with some very useful tools that can greatly simplify things for them:
- Simple, easy-to-build solar ovens (to reduce the need for firewood and all the negative implications that come with it)
- Sand-gravel-charcoal water filter (to clean the water from the 20,000L pond in order to use it for washing and other uses)
- Solar disinfection system for water (to purify water from the 1000L tank)
Urban Pool-to-Pond Conversion – Two-Year Progress Report
Aquaculture, Biological Cleaning, Conservation, Fish, Irrigation, Natural Swimming, Plant Systems, Urban Projects, Water Harvesting — by Stephanie Ladwig-Cooper October 28, 2011
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.

Nyumbani Village, which is a program of the Children of God Relief Institute (COGRI) caring for both HIV infected and affected children, aims to establish a self-sustaining, community-based residential village serving children orphaned as a result of HIV/AIDS. This is being achieved through providing a family like settling where the orphans are under stewardship of destitute elderly grandparents in a family like structure and are provided with adequate social support, high quality clinical nursing and counseling, and both educational support and vocational training.

Roving, roving. I’m now staying in Central Tokyo, at my usual home with the Ota family.
This morning I reached for the broom, I got a surprise. Professor Ota came running out "No No!"
He bent down, fiddled with something on the floor, and out it sprang — the floor-sweeping robot.
Comments (3)Hemp for Victory?
Biological Cleaning, Food Plants - Annual, Plant Systems, Seeds, Village Development — by Craig Mackintosh PRI Editor June 23, 2011
I figure this video will stimulate some potentially useful discussion. It features portions of an interesting WWII-era production, titled Hemp for Victory, made by the U.S. government to encourage U.S. farmers into the cultivation of hemp to fill the escalating demand for industrial fibre during the war. This was not too long after the U.S. had introduced, during the height of the Great Depression, the 1937 Marihuana tax, which had had the opposite effect. (It goes to show the power that government policies can wield in rapidly influencing social priorities.)
Some of you will know, and some of you will not, that hemp has been used since ancient times. Sails were made of it, ropes were made of it, clothes were made of it. People ate it (seed), wrote on it (paper), lit their homes with it (oil), and fed their animals with it (what was left!). Indeed, some say there’s very little you can’t make from it. As the video shows, Henry Ford even made cars and car parts out of it. Not only were they stronger and lighter than metal parts, but they were biodegradable too!

Comments (3)Permaculture in Public Spaces
Alternatives to Political Systems, Aquaculture, Biological Cleaning, Community Projects, Conservation, Courses/Workshops, Land, People Systems, Village Development — by Lindsay Dailey March 19, 2011
Lake County, California, is a rural area on the edge of the San Francisco Bay Area. Though it’s surrounded by extremely wealthy areas, Lake County is unique; it is one of the least densely populated counties in the state of California, with one of the highest rates of poverty and unemployment. The agricultural industries that once thrived in the area are mostly gone, and most people struggle to earn a livelihood.
Leave it to the permaculturalists to find opportunity in this seemingly barren edge! And there is indeed permaculture activity on the rise, in the most unlikely of places… the county government.

“I don’t know. It’s really familiar. It smells like… cat food,” I reply.
“It smells like shit,” he says.

Editor’s Note: This article was written in mid-December, when Queensland’s rains were nothing like that witnessed of late, and which have caused the catastrophic flooding in many towns and cities across the state. I mention this to ensure people realise Nicola was not being insensitive with timing of a Queensland- and water-based article. Our thoughts go out to all who have suffered in the recent deluges.
Pit-falls, projects and laughs from our Permaculture journey
If women knew diggers looked this good I think swales would pop up like weeds
around the globe. Gee whiz. Beats a four-tonne excavator in my books
– even if it had a swivel bucket.
Chris woke up the other day and declared, “I think I can dig those swales by hand.”
“Super,” I said, “go for it!”
Comments (13)Constructing a Fishpond Dam
Aquaculture, Biological Cleaning, Dams, Fish, Land, Natural Swimming, Plant Systems, Water Harvesting — by Geoff Lawton November 26, 2010
The spillway that sets the height of the water and allows for passive
discharge of surplus water during large rainfall events
We can build a dam to serve specifically as a fish pond and which can be designed to be more productive for aquaculture systems generally, compared with stocking an existing farm dam with fish. As most of the production occurs in the upper levels of water, a depth of under 2 metres allows you to feed and harvest the fish easily and bring them to a desirable size as quickly as possible. Using an example of the chicken tractor, infrastructure design can also be applied to fish to create a more intensive system where resources such as the animals’ manure are cycled and productivity is increased whilst benefiting the surrounding systems. The ideal style of dam for the purpose of fish production is the contour dam, which is dug into the side of a shallow sloping hill (on a reasonable flat landscape) with a dam wall of a semi-circular curve or a semi-square shape. The profile of the dam floor can be easily constructed so that it is flat, and the inner walls and back-cut of the dam can be reasonably steep, maximising the volume and minimising the challenges of harvest, whilst maintaining a consistent temperature.
Comments (16)Jordan Valley Permaculture Project – November 2010 Update
Aid Projects, Biological Cleaning, Building, Community Projects, Conservation, Demonstration Sites, Education Centres, Irrigation, Urban Projects, Waste Systems & Recycling — by Geoff Lawton November 17, 2010
The Jordan Valley Permaculture Project (aka ‘Greening the Desert – the Sequel’) in Al Jawaseri in the Dead Sea Valley (lowest place on earth), continues to develop as we gradually fund the project into action with our own permaculture education programs, volunteers and funding from Muslim Aid Australia and Kids are Sweet of Wisconsin, USA. The male and female shower and compost toilet block is now reaching completion using a basic faralone design system (PDF, with others composting toilet resources here, here, here, here and here). A reed bed has just been built as part of the shower block waste water system so that we can demonstrate grey-water reuse for garden crops. A small nursery has been funded by one of the volunteers involved in this project, Damien McAnany, and it is now producing a selection of vegetable, fruit and tree seedlings. Damien organized his own fund-raising initiatives in the USA then volunteered for a few weeks on site. Other volunteers Jesse and Tanya Lemieux, Eric Seider, Wade Tait, Dave Spicer have all put in time and work to help push the project along. The trees planted on the site have just survived one of the hottest summers on record and are still growing well. The lower areas of the site now have quite extensive vegetable gardens which are coming into their first winter production.
Comments (8)Reducing Urban Water Use
Biological Cleaning, Compost, Conservation, Potable Water, Rehabilitation, Soil Conservation, Soil Erosion & Contamination, Storm Water, Waste Systems & Recycling, Waste Water, Water Contaminaton & Loss — by Earth Policy Institute November 4, 2010
by Lester R. Brown, Earth Policy Institute
U.S. President Theodore Roosevelt once noted that "civilized people ought to know how to dispose of the sewage in some other way than putting it into the drinking water."
The one-time use of water to disperse human and industrial wastes is an outmoded practice, made obsolete by new technologies and water shortages. Yet it is still common around much of the world. Water enters a city, becomes contaminated with human and industrial wastes, and leaves the city dangerously polluted. Toxic industrial wastes discharged into rivers and lakes or into wells also permeate aquifers, making water—both surface and underground—unsafe for drinking.
Comments (3)How to Handle Biomass in Dry Tropical Systems: Mulch Pit Gardens
Biological Cleaning, Compost, Courses/Workshops, Food Plants - Perennial, Fungi, Irrigation, Land, Plant Systems, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation, Structure, Waste Systems & Recycling, Waste Water, Water Harvesting — by Andrew Jones October 29, 2010
The dry tropics cover a significant land area of the planet, particularly around the regions of the tropics of Cancer and Capricorn. Characterized by a majority of the year when evaporation potential is greater than rainfall, they also support rapid biomass growth during and following the rainy season. Legume species normally form a significant portion of the species present, and provide for rapid biomass production.
Management of this biomass can be tricky, particularly when left above ground in dry mulch piles, as it normally stays dry, inhibiting both fungal and bacterial breakdown. On the flip side, dry tropics soils, whether sandy or clay-based are in need of organic matter to balance structure, enhance water retention or drainage and build humus. One approach for creating such conditions are mulch pit gardens.
Papaya, banana, and coconut circles are developed by digging pits up to two meters in diameter (for papaya or banana – up to three meters for coconuts) and about 1 meter deep. These are then filled with dampened, compacted organic material to a height of 1 meter above ground. Up to seven plants of the appropriate type are then planted in the rim of the pit. Taro or other moisture loving plants may be planted on the inside edge, and sweet potato along the outside edge to provide a living mulch as well as extra production.

Strawberry Fields Eco Lodge, Ethiopia: Black Water Filtration System
Aid Projects, Biological Cleaning, Community Projects, Demonstration Sites, Education Centres, Land, Waste Systems & Recycling, Waste Water — by Alex McCausland October 26, 2010
Black water is the term applied to domestic waste water which carries solid organic waste materials and has a high level of nitrogen and phosphate containing compounds which may be in soluble and non soluble forms. Black water is generally assumed to refer to discharge from flush toilets, while grey water refers to outflow from showers, baths and hand basins, which contains no solid material and generally lower levels of nitrates and phosphates. Since all our toilets at Strawberry Fields are dry composting toilets our black water system does not have to deal with human waste at all. However, what we are dealing with is the waste water from the kitchen. Kitchen water can be considered as black water because dirty plates, frying pans and utensils carry a lot of fats, starches and protein. As well as this, the detergents which are necessary to remove all those from the surfaces of the utensils are stronger than body soap and carry a lot of phosphates which need some breaking down. The resulting mixture of soapy water, fat, protein and starch will quickly become very rancid if bacteria begin breeding in it, as it will go anaerobic and start producing swampy smelling gasses like nitrites which are poisonous to most plants (except for swamp plants which are adapted to deal with them).
