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.

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)

Last week Permaculture consultant Nick Huggins spoke to Anne Delaney from the ABC Riverina Breakfast radio program in Wagga Wagga, NSW. Listen here:
A backgrounder: Two Permaculture consultants, currently drought proofing a property in Livingstone, are calling for an end to the Australian Government’s water buy-back scheme, saying turning off the taps rather than helping farmers repair degraded landscape is selling the Riverina’s future short.Comments (9)

‘Soil, Water & Carbon for Every Farm’ – Building Soils, Harvesting Rainwater, Storing Carbon
by Abe Collins & Darren Doherty
Keyline Design was first developed by the great Australian, P.A. Yeomans (1904-1984), in the late 1940s & 50s initially as a practical response to the unpredictable rainfall regime he found on his new property, ‘Nevallan’, to the west of Sydney, New South Wales, Australia. Soil Conservation, as developed by the US Army Corp of Engineers was the predominant practice of the time and for a time Yeomans was influenced by this, though soon found some deficiencies with the pattern of water flow its application expressed. Yeomans went on to devote the rest of his life to the promotion, research and development of Keyline Design and in doing so was labelled by Permaculture co-originator Bill Mollison as "…one of Australia’s greatest patriots… ".
Influenced by the likes of prominent organic agriculture figures in Andre Voison, Friend Sykes, Newman Turner & Louis Bromfield (among many others!) Yeomans has been attributed with being the 1st person to accelerate soil formation through the stacking of methods, overturning the myth that it took 1,000 years to create an inch of topsoil. Yeomans proclaimed that "…the landman’s job is not so much to conserve soil as it is to develop soil, to improve his soil and to make it more fertile than it ever was…".Comments (0)
