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.

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.

This year I have been in Haiti after a downgraded hurricane, and then in New Jersey a week after Sandy. While in New Jersey two tornadoes passed by my old house. What do they have in common?
In each case water was being limited in its flow by developement or the removal of natural structures that diffuse its energy. While working in Haiti and trying to build large enough swales to catch water, it was instantly apparent after the first five-inch rain that what we needed to do was slow it down and catch the sediment.

I’m not sure it’s possible, looking back now, to say exactly what I was expecting when I hopped on that plane and flew to Ethiopia for an internship at Strawberry Fields, but one thing I am sure of is that it’s been one of the most transformative, edifying experiences I’ve had in my life.

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 (0)Let the Water Do the Work: Induced Meandering, an Evolving Method for Restoring Incised Channels

The volume reviewed below comes highly recommended for all Permaculturists working in or around any water channels, and particularly on the broad-acre. While the methods happen to apply most immediately in drylands, they will apply directly anywhere that erosion, down-cutting, rapid gully formation, and other forms of channel incision occur. Keep in mind that these techniques will also apply in ephemeral channels that only carry water during rare rain storms, and are otherwise ‘dry.’
Importantly, even if you are working more within mesic environments and do not see a lot of actively incising channels, just the knowledge you will gain about stream dynamics and working with various stream powers and flood-regimes will be applicable and invaluable to your work. These factors, such as the ‘bankfull’ flood, and the specific inter-relations and ratios of multiple stream variables remain the same as basic physics of water flow no matter what the environment. These physics will dictate exactly where and where not to place any kind of built structure within an active water channel, and enable you to predict results of your efforts with much greater precision. How many of us doing this kind of work have lost stream structures to a “gully-washer”? The knowledge and approach in this book could have saved many a headache, cash outlay, and enabled construction of more durable, persistent, and ultimately useful work.
Positive Examples of Agricultural and Community Transformation in Kenya

I’m adding the following clips as a positive supplement to the preceding post. I think it’s important to see that positive work is happening, and that GMOs are not only not needed, but they are a definite threat to these excellent efforts. Permaculturists working, or intending to work, in Kenya could potentially find ways to network with organisations like these, and to offer extra design tools to further strengthen their efforts.
The first video is from the Grow Biointensive Agricultural Center of Kenya (G-BIACK), who look to be doing some great on-the-ground work to educate and transform Kenyan communities and help them return to more resilient, affordable and healthy agricultural and community systems.
This second clip, from The Haller Foundation, will be especially appreciated by permaculturists — it’s a fantastic video show-casing some excellent permaculture action, also in Kenya:
Comments (4)Earthworks Course – Zaytuna Farm, The Channon, May 2011

The sun works on an 11 year cycle over which it radiates heat at varying levels upon the earth. The cycle is observed by counting the frequency and placement of sunspots visible on the sun. Currently we are at a peak of the cycle whereby the sun is radiating a maximum amount of heat and energy. This means increased evaporation off the oceans’ waters and therefore increased precipitation over our lands. When the sun moves towards its less generative stage of the cycle, less evaporation occurs, which means less precipitation and impending dry conditions.
And so the rains have come down upon Zaytuna farm — 111mm in 5 days. The dams are full to the freeboard, the swales are soaking in the sediment, the spillways are spilling, the swivel pipes are swivelling, the soil is having a regeneration party, and the plants are just hangin’ out doing their thing.
And the earthworks have been stopped in their tracks….
Comments (2)Al Baydha Project, Saudi Arabia: Fence vs. Earth Berm
Demonstration Sites, Earth Banks, Fencing, Gabions, Land — by Neal Spackman May 9, 2011
Editor’s Note: This is an update on the Al Baydha project we introduced here.
In order to demonstrate our agricultural system, we need to keep goats, camels, and sheep off the site. Initially we were planning to build a standard chain-link fence, but decided we could do better. Instead, we are putting up a big earth berm — about 2.5 meters tall and between 4 and 5 meters wide, with a layer of large stones securing razor wire on top .
PRI Ridge Point Dam Earthworks
Conservation, Dams, Earth Banks, Irrigation, Land, Material, Natural Swimming, Swales, Water Harvesting — by Gordon Williams April 7, 2011
On the 31st of January the Permaculture Earthworks course at Zaytuna Farm began with good weather and a group of enthusiastic students ready to see the process of laying the groundwork for functional rainwater harvesting features in landscapes. During the week a variety of works were conducted across the property, including a new dam and swale, swale pipe crossings, building site levelling and, to make everyone’s life a little bit easier, the excavator divided some clumping bamboo.
The first task for the 25-ton excavator was to construct a ridge point dam connected to the end of an existing swale, so as to increase catchment. If the dam were to be built independent of the swale it would not naturally fill. The primary purpose of this dam is to increase the volume of water stored on the property at a height where it can be gravity fed to areas below for use.

Is it any wonder with daily reminders of the widening disparity between exponential population growth and water and food scarcity, so many of us begin to question the possibility of long term sustainable human habitation on the planet? Being a constant witness to damage caused by modern agricultural practices — motivated and driven largely by corporate greed — is proof enough that our ineffective systems have to change and come back into balance. My recent post in Jordan opened my eyes to this reality more than ever before.

Permaculture at the Al-Baydha Project in Saudi Arabia – Neal Spackman, Video 1
Community Projects, Demonstration Sites, Earth Banks, Gabions, Land, Swales, Terraces — by Craig Mackintosh PRI Editor January 14, 2011
Do you remember Geoff’s recent Saudi Arabia consultation? Well, left behind in the Kingdom as project manager to implement the work is Neal Spackman. Neal has kindly followed up on my request for reports, providing the video and images below. After the video I’ll give you a little more swivel-chair commentary based on info I’ve had via email.
The new site recently sustained heavy rainfalls. Older locals said it was the biggest storm the area has seen in more than twenty years. It was great timing for the fledgling project, as it gave opportunity to show exactly where the incomplete system required more work, and where it was working well.
The following image of a road busted up by one of the flash floods gives a decent concept of how much rainfall suddenly descended down hillsides largely devoid of any vegetation that would otherwise slowed its progress and reduced its destructive force:
Comments (17)Piped Swale Crossings
Conservation, Earth Banks, Irrigation, Land, Soil Conservation, Storm Water, Swales, Waste Water, Water Harvesting — by Geoff Lawton November 13, 2010
Permaculture is a connecting system between disciplines and elements in a matrix of design, and swales are a mainframe element. The efficiency of swales is that they can interrupt water surface flow high in a landscape where it is then infiltrated relatively quickly, on contour, and moves incredibly slowly through the landscape soil and subsoil profiles. This becomes a great advantage to the potential productivity of any property, especially a property that is designed to be diverse and interactive with many ecosystem elements. When you design a property this way, a mainframe approach as a consultant designer is:
