*Global CA-CoP* *CONSERVATION AGRICULTURE COMMUNITY OF PRACTICE* *for sustainable agriculture and land management* Dear Subscribers, Please see herebelow a link to a twelve minute video of Walter Jehne discussing the soil carbon sponge produced by Seth Itzkan of Soils4Climate. The link to more lectures by Water Jehne is also provides herebelow. Thank you Seth for sharing. *Amir Kassam * *Moderator* e-mail: [log in to unmask] URL: www.fao.org/ag/ca *Conservation Agriculture is an ecosystem approach to sustainable agriculture and land management based on the practical application of locally adapted three interlinked principles of: (i) Continuous no or minimum mechanical soil disturbance (no-till seeding/planting and weeding, and minimum soil disturbance with all other farm operations including harvesting); (ii) permanent maintenance of soil much cover (crop biomass, stubble and cover crops); and (iii) diversification of cropping system (environmentally, environmentally and socially adapted rotations and/or sequences and/or associations involving annuals and perennials, including legumes and cover crops), along with other complementary good agricultural production and land management practices. Conservation Agriculture systems are present in all continents, involving rainfed and irrigated systems including annual cropland systems, perennial systems, orchards and plantation systems, agroforestry systems, crop-livestock systems, organic production systems and rice-based systems *(more at: www.fao.org/ag/ca). ---------- Forwarded message --------- From: Seth Itzkan <[log in to unmask]> Date: Sun, Aug 19, 2018 at 11:32 PM Subject: Re: Really, really important... Walter Jehne - The Soil Carbon Sponge, Climate Solutions and Healthy Water To: Amir Kassam <[log in to unmask]> Hi Amir, Please also forward to your list this shorter video of Walter Jehne that I produced. It is only twelve minutes that might be a bit more viewable. It is available on YouTube and Facebook at the links below, as well as some highlight quotes. Thank you, Seth Walter Jehne Discussing the "Soil Carbon Sponge" https://www.youtube.com/watch?v=rAbAf-GbRHc https://www.facebook.com/groups/Soil4Climate/permalink/2116850458586697 Walter Jehne of Healthy Soils Australia discussing #methane and carbon markets at the Soil Carbon Sponge Seminar in Vermont, organized by Didi Pershouse. Interviewed by Seth Itzkan of Soil4Climate Inc., https://www.soil4climate.org/ https://www.facebook.com/groups/Soil4Climate/ More info on Walter's lectures are available here https://www.didipershouse.com/soil-carbon-sponge-seminars.html Note: Walter accidentally said in the first few minutes "20 billion tons of carbon per annum per hectare." He meant to say "20 billion tons of carbon per annum (for all land)," and not per hectare. "It’s water that governs 95% of the heat dynamics of the blue planet, and it’s really only the water that can now safely cool the planet naturally. So, now we’re really saying, how do we rebuild that sponge to rebuild the hydrology to rebuild the natural, safe cooling, because only that can offset global warming and give us the safe future we need. " Regarding Cows & Methane: "The photo-oxidation rate above a healthy green pasture is 100 times the rate of the methane production of the cows grazing that pasture. A healthy green pasture transpiring water will result in the production of these hydroxyl radicals from this photo oxidation more than able to breakdown all the methane that the cattle grazing it might produce. In fact, 100 times the rate. This is the punch line, you see, because grasslands can not exist anywhere on the planet without their natural symbionts, without their natural herbivores, It is the cows managing healthy green pastures that are really the earth’s only critical means to keep this methane level down. Methane levels have gone up abnormally in the last decades, largely because of fugitive emissions from leaking gas wells. And now from fracking, they’ve gone up three, four fold, but it has nothing to do with cows. It’s all about these gas, fugitive emissions, but cows have become the very very simple patsies or scape goats to blame for this effect." - Walter Jehne, Healthy Soils Australia. -- Seth J.
