Community Projects, Conservation, Irrigation, Storm Water, Urban Projects, Water Harvesting — by Jennifer Wadsworth May 18, 2013
At 7:30 Sunday morning, April 21, 2013, people began to gather on a barren lot in downtown Phoenix, Arizona. The temperature was already climbing into the 80s and the lot’s bare dirt reflected both heat and light, making lingering uncomfortable. By 8:00 AM, more than 30 neighborhood volunteers, Youth Hostel guests, Green Living Co-op members, PDC and university students were on-site, eager to start the day’s activities. They were here to celebrate Earth Day by installing a green infrastructure retrofit project in the Garfield Historic District; an eclectic neighborhood that is part of the larger Arts District.Comments (2)
Strawberry Fields Eco Lodge: Kitchen Grey-Water System Report of Implementation and Design Update (Ethiopia)

As most of us know, grey water is a term used to refer to “waste” water that has been used once in any domestic system except for toilets (which is referred to as black water). However grey water from the kitchen may be considered as “dark grey” water on account of the fact that it tends to contain a lot more fats and protein from the grease and grime that comes off pots and pans than say shower outflow water which is quite dilute. If you let kitchen grey water sit around it quickly goes rancid and doesn’t smell a lot different from sewage. The grey water coming out of our kitchen also has some pretty nasty detergents in it (Ajax) and we can’t really get hold of anything more eco out here in Ethiopia. Initially we tried putting this grey water directly into an infiltration pit, but that didn’t work very well as it tended to fill up and start to reek and kill the surrounding plants, especially in the rainy season.Comments (3)

Plan the work then work the plan. — P.A. Yeomans
In the mid 1950s, Australian engineer P.A. Yeomans demonstrated a new system of land management he called the Keyline system. The consensus of the time, championed by people like Dr H.H. Bennett, was that soil was a finite resource and that once depleted “it was irretrievably lost as if consumed by fire”. P.A. understood that long natural carbon cycles create soil, but also knew that this process takes hundreds or thousands of years. By adjusting the conditions in the soil with his plowing and management techniques, P.A. was able to speed this process and create dozens of millimeters of fertile topsoil in just one year.Comments (5)

This excellent little 20-minute video does a great job of covering the basics of watershed management and landscape rehydration. You won’t hear the words ‘permaculture’ or ’swales’ once, but it’s clear that both are in use here, to great effect. If we can get these simple but profound concepts driven into social consciousness, and applied broadscale, we would see that investment in labour pay dividends, as many of our increasingly expensive natural disasters and resource limitations would simply disappear, as we reinstate nature’s own moderating capabilities.Comments (7)
Demonstration Sites, Food Forests, Food Plants - Annual, Food Plants - Perennial, Global Warming/Climate Change, Irrigation, Regional Water Cycle, Trees — by Chris McLeod January 15, 2013
What a difference six weeks has made to the food forest here! The change in climate between cool and wet to hot and dry happened in less than a week during early October and since that time there has been no significant rainfall. The rain probably won’t fall here now until about April based on past experience and records.
The abrupt change surprised me and I took a while to come to accept that the climate had altered here that quickly, but after this realisation I undertook to heavily mulch all 300+ fruit trees. The purpose of this is to keep the plants’ root systems cool and reduce the evaporation of ground water. The mulch does have the adverse effect of scavenging nitrogen from the top soil which causes further stress to the fruit trees, but this is only temporary and the impact is much less than the stress caused by the loss of ground water due to evaporation.Comments (13)

Our one month long internship at the Greening the Desert Project (the ‘Sequel site’) just ended. Ten students arriving from seven different countries were part of the first internship to take place at the project site in the Dead Sea Valley in Jordan. This will be a journey through pictures on what Geoff, Nadia, the interns and the WWOOFers were up to.Comments (7)

Someone remarked to me yesterday that the fruit trees in the food forests here at the farm must require an extensive irrigation system. But, in fact, the fruit trees in the food forest here have to survive on rainwater alone, as I only have enough water for the vegetables and herbs.Comments (4)

Shibam: UNESCO World Heritage site
I was recently privileged to be part of the team that accompanied Geoff and Nadia Lawton along with Mr. Tashi Dawa in a very interesting consultancy in the Southern Yemen, specifically The Hadhramaut Valley, or Wadi Hadhramaut.
Geoff was invited by the “Reconstruction Fund of Hadhramaut and Al-Mahra” to give his opinion on what could be done in the valley in terms of flood mitigation and water harvesting from a permaculture point of view.Comments (10)

Filmmaker and environmentalist, John D. Liu from the Environmental Education Media Project team, takes us to Rwanda again (last time was here), showing us how the country is seeking to leapfrog the disastrous ‘development‘ route most of the countries of the North have gone down, to instead head more directly towards sustainability. Given the horrors this country were awash with during the 1990s, it’s certainly encouraging to see the nation making some good truly forward steps on several fronts.Comments (2)

At time of writing, our Zaytuna Farm Video Tour video has had almost 11,000 views, after only six months. A lot of people expressed their appreciation for this video, with some describing it as a "free DVD". Where we can, we want to provide more inspirational/instructional material for free, and today I’m writing to let you know about our latest effort towards fulfilling this goal.

This week the project started planting the swales with 1000 very hardy desert trees. The team is working in shifts of laying drip line, digging holes, manuring and mulching swales, putting in compost, planting, mulching again, and then adjusting the drip emitter.Comments (7)

PDCs are tricky. For two weeks we tumble into this community of unfamiliarly familiar, curious strangers. The constant whirlwind of habits, obligations, and distractions that composes our lives momentarily dissipates and we are thrust into this world where our main responsibility is to be open-minded, observe, think, learn, and connect. Yet, at the end of the day, we are singular beings and we all have our lives that we will return to. As PDC participants, we are exposed to this new paradigm together, share bemusement at fractal patterns and individual inspirations, and then suddenly depart the entropy we fell into and hopefully go off with the intent to use permaculture as a framework for making society and the environment more resilient.
However, after I was formally introduced to permaculture, as a nomadic recent college graduate, I was not sure how permaculture could be a tangible part of my life. The fulfillment from a sense of belonging and purpose I experienced during the PDC instilled within me a restless need to contribute to a project and/or community. So, I found myself asking, “Now what?”.Comments (4)

Editor’s Note: Regular readers will have appreciated Alex McCausland’s regular and comprehensive reports from precariously positioned Ethiopia, and the great work he and his team have been doing on the ground. If you want to learn practical permaculture and gain real-world permaculture aid work experience in a location rich in agricultural history, then please consider taking Alex’s next PDC, to be held in southern Ethiopia between December 10 — 22, 2012. Your tuition fees directly support this important educational aid work.
The Hafto Solar Community Water Project site project is a solar powered water supply facility for the surrounding community of Hafto in the Hadiya Zone, South Ethiopia. The project was planned and implemented by a German NGO called DWC and is owned and run by a local NGO called SMART. The facility supplies water to about 1500 surrounding community members within an approximate 1km radius. There is a small charge for the water of about 0.01 Ethiopian Birr per liter (1$=18Birr) which covers the running costs of the project. The community members currently come to the site with donkeys to collect the water in jerry-cans which they take home for use.Comments (3)

At the top end of the Marshalls’ property on the Southern Tablelands, NSW, Australia, the creek is bone dry. This spot, fed by 1250 Ha of native forest, has been that way for 10 weeks now.
Meanwhile, 1.2 km downstream at the base of their property, flowing past the fodder poplars, the bamboo and the ferns and dense native revegetation (where only blackberry stood twelve years ago), is one and a half megalitres of the crystal clear water you see in the photo above; every day. Since the creek dried up at the top of their property, 120 megalitres is a conservative estimate of the base flow that ‘the sponge’ that is ‘Sunningdale’ has continued to release to the landscape below. This is despite a catchment increase between the two sites of only 8% and five out of the last six months of rainfall being well below the average.
What’s the catch? If you’d like a bit of background on how a property like Peter and Kate Marshall’s, which has reinstated the original floodplain hydrological processes, is able to store and then slowly release water, check out the simple diagrams below.Comments (4)

I always thought that rain was a nurturing and gentle aspect of nature. You know how it is, you get a bit of rain and it helps all of the plants to grow, provides water for us and the animals and generally stops the place from drying out. That was my thinking back in an urban environment. In that area, the drainage infrastructure had been developed and maintained over the past 120 years and it just worked. In fact, the infrastructure was so good you never really thought about it.
In a rural location however, there is usually little to no infrastructure, so any change you make to the landscape will change the way water interacts with that landscape. Winter rain here is usually quite gentle with many hours of sustained drizzle and relatively high humidity. These conditions generally don’t present too many challenges. Or so I thought.Comments (0)
