How to green the world's deserts and reverse climate change | Allan Savory

Оценок: 66328 | Просмотров: 2705914
"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And terrifyingly, it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes -- and his work so far shows -- that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

I have been seeing this happen on my own land for the last few years. When I try to talk to people about what is happening, they look at me like I'm crazy,,, but I've lived on my land for 50 yrs and I KNOW what my earth is suppose to look like. This is what is causing the flooding everywhere you look. This presentation is the ONLY thing that makes any kind of LOGICAL sense out of anything I've heard from ANYONE the last few decades from ANYONE. It also answers so many questions about what is going on today, in 2019, and the BS the UN tells everyone, as they have the Gov'ts take over ALL the privately owned land. I hope MORE people listen to this and WAKE UP, and the chemical Geo-engineering weather modification that is so RISKY to the people, the animals, the land, the oceans, rivers, etc., is STOPPED until FULL transparency is provided and the PEOPLE are told what they are doing, what they are spraying, and what all the RISKS are involved. There is a ethical moral obligation that SOME have decided to toss out the window at the expense of billions of people and wildlife.

Industrial hemp is an excellent plant to use in reforestation efforts. The hemp plant provides food for lives talk and humans alike, and the fallen leaves fertilize the soil. The roots of the hemp plant spread about 3 feet in diameter preventing erosion. Hemp also grows in poor soil conditions and detoxifies toxic soils.

I wonder if you guys missed it but this man killed 40,000 elephants. Imagine he did that to humans, I suspect he would be behind bars or killed. How can anyone calling themselves an environmentalist agree with what he's saying here. It is impossible to turn to grazing on grass because we simply don't have enough land to do that and match the demand for meat. Scientifically manufactured meat is the way forward.

+Lucas Johnson You said we are the only ones with a moral compass and intelligence to understand these concepts, and by extension of that logic this man should've known better. In society we punish people for such mistakes and there should be no exception for him. Secondly, I would encourage you to look at the UN study on global warming and the contributers and realise that what he's saying is bs. Funny how you ignored the second part of my comment. Was it too true to comment on?
Lucas Johnson (5 дней назад)
"Imagine if he did that to humans..." Why? Why should anyone compare animal deaths to human deaths? They are not the same. Animals are important of course, but they are ultimately just the means to the end of helping humanity to exist and grow. Only humans have abstract thought processes, high level communication, advanced consciousness, science, literature, and apreciation of beauty. Heck, only humans even have a sense of moral right and wrong; even if you could tell an elephant that someone killed 40000 of its kind, it would not care because it is not programmed to. Animals have no moral compass; only humans do. We are the culmination of evolutionary design, or if you are religious, children of God. Animals are not. They are useful to us, and therefore should be preserved wherever possible, but they do not and should not be treated as equals to humans as you seem to suggest.

This old man still hasn't given up on the mistakes he made as a young man. He believes strongly that nature needs to be managed by humans. The answer isn't animal agriculture, it's rewilding land with natural grazing animals and predators. I don't know what that looks like in Africa, but in North America it is buffalo and wolves.

In other words the loss of wildlife and the destruction of natural ecosystems by human expansion has lead to dessertification due the creation of human adapted lands. This would not redcude livestock emissions but it would atleast help dessertification and create a more free-moving/natural life for all livestock and other animals.

Any small-scale chicken farmer will attest to the significant re-grassing that occurs after moving their portable chicken coops (called tractors). This evidence further supports Allan's claim. It all makes sense now. Another cause of desertification can be soil salinity. Parts of Australia are experiencing this due to a rising water table which is the result of over-irrigation. Salt in the ground is being pushed up towards the tree root level just beneath the surface and the trees and grasses are dying. Once the ground cover has gone the top-soil then erodes and gets blown away in high winds, even causing dust storms. https://youtu.be/0TDQO-mxTb8

This was explained in another Savory video, when land degraded so badly that it wasn't holding any rain, as a last ditch effort, farmers got bulldosers & created makeshift dams to at least catch the rain as it poured off the hills. In this example, once holistic grazing was in use, another person saw the farmer who owned this land with a bulldozer again & asked him what the heck he was doing & he explained that he was filling in the holes so he didn't look like a complete moron in the future by leaving the scars of his stupidity present. The land was healing, it was absorbing water, so those makeshift dams were sitting empty because the water was now in the soil, so they weren't needed & he didn't want anyone in the future to know he had so badly mistreated the land that he had enough run off to create pools of water that size

How could we make co2 desolvable for the soil?
Lilac Lizard (14 дней назад)
CO2 is Carbon 1 & Oxygen 2 (carbon shortens to C & oxygen to O) Charcoal is 100% carbon in solid form. So when you burn a plant & create charcoal, what you're doing is removing all other parts of the plant except for the Carbon they've converted from gas form to solid form. In the same way you can burn it to obtain carbon, inside the soil, microbes will conduct special processes to convert the carbon in the roots into soil, permanent solid carbon. So to put it simply, plants will do all the work, we just need to provide the microbes with somewhere to live so they can then convert the plant material into soil carbon

If all goes as proper ALBERTA will be the start of great CANADIAN protectionism against UNs destruction, after 1992 UN Climate Summit as you can see it is well on its way if we don't stop it & BAN THE UN from all of CANADA! Not rocket science ladies & gentlemen, it is always about the economy. Whos at fault? Federal & Provincial acceptance of UNs 1992 CLIMATE SUMMIT, when 192 countries allowed UN control to destroy every country from the inside out. UNs unelected control to socially engineer society to destroy its own industries & its own economies, all with diabolically planned ENVIRONMENTALISM & CLIMATE CHANGE. https://www.youtube.com/watch?v=gJ8f4RxGbP8 ------------------------------------------------------------------------------------With UN control of education (dumb down) to 24/7/365 UN media control it has claimed 2 generations in 26 years. Under 40 +- & a retired portion of retired baby boomers that now have time to watch the UN propaganda on their TV, the radio & read the newspapers. GEORGE Orwell's BOOK & MOVIE was & is the plan of our futures if we don't wake up & snap out of it. Some say we are living in BIBLICAL END TIMES another diabolical manual to accept our own destruction by the UNITED NATIONS ELITE 13 FAMILIES. This is coming from the UN control to streamline everything in the world for control to destroy. 🤦‍♂️ https://www.youtube.com/watch?v=qX86OnqAxBs&t=325s https://www.youtube.com/watch?v=GQxOKXEff4I https://www.youtube.com/watch?v=KSEGfei_7Ic&t=517s --------------------------------------------------------------------------------I knew of this years ago but believed Canada would not fall for this trick. Unfortunately, I wasn't paying my now graduated children are dumber than sacks of hammers not knowing MATH, SCIENCE, SOCIAL like we were taught. So now we have a generation of non-thinkers & only follow, easy to control & destroy. As far as the retired, they seem to forget their past & have no vision for the future of their childrens children & beyond. This I sadly witness from my own mother, friends & foe alike. What do you think? Do you think? Can you think? https://www.youtube.com/watch?v=o0UGWNpRBdY --------------------------------------------------------------------------------We now have to reverse the generational deterioration of society. NOW, if we do not it doesn't matter who we vote for or where we go. We separate the mainstream globalist UN DESTRUCTION parties (LIBERAL, PC, UCP, NDP) from the only made in ALBERTA for ALBERTA "ALBERTA ADVANTAGE PARTY!

When do we re-introduce the original animals? Is that even possible?
Lilac Lizard (14 дней назад)
Any large grazers must be kept in a tight herd & constantly moving for this to work, so if you want the original animals, you can find the funds for human herders to move them instead of livestock, or reintroduce predators to follow them & keep them in a herd & constantly moving. Alternatively, look at the doco "running out of time" about Savory's ranch, they're using the livestock to manage the land & the native animals are naturally returning & herd sizes getting bigger & bigger as the land improves due to livestock management, but they're not really herding in the traditional sense, so livestock will always be needed to maintain the conditions in that setting

Before you get too excited by this seductive talk, please read this rebuttal from the Sierra Club: https://www.sierraclub.org/sierra/2017-2-march-april/feature/allan-savory-says-more-cows-land-will-reverse-climate-change . Careful investigations have not confirmed the claims he makes for the effectiveness of his techniques, while his claim that grazing reduction is damaging are not shared by most grassland experts - he simply misrepresents the evidence. And even if his techniques did work, his claim that the resulting carbon sequestration would reverse climate change is quite simply not supported by the facts - he overestimates the potential impact by almost an order of magnitude.
Tullochgorum (20 дней назад)
+Lilac Lizard Many thanks for all your links - I'll read them with care. Though your claim that the Sierra Club is driven by some kind of extreme vegan agenda is decidedly odd. There is a vegan community group, amongst dozens of other groups, but they have no official standing. The Club itself is open to all views - see this, for example: https://www.sierraclub.org/sierra/green-life/toward-moral-case-for-meat-eating
Lilac Lizard (20 дней назад)
+Tullochgorum _"Well, your rebuttal comes from"_ and yours comes from a pro-vegan site hellbent on destroying Savory at all costs because it completely discredits everything vegans are trying to claim, so both are on par. I never said that rebuttal was highly credible, it's just a dam good match to the sierra club on credibility level If you want genuine evidence to support holistic grazing, as opposed to just a counter to the vegan agenda, then sure, here you go https://www.tropicalgrasslands.asn.au/Tropical%20Grasslands%20Journal%20archive/PDFs/Vol_34_2000/Vol_34_03-04_00_pp207_218.pdf http://www.regenerateland.com/evidence-supporting-holistic-management/ https://www.sciencedirect.com/science/article/pii/S1470160X15006299 http://www.grazingbestprac.com.au/research/grazing/AGEE3851%20Grazing%20management%20impacts%20in%20north%20Texas%20v12011.pdf & if you want anecdotal evidence it works, here you go https://www.farmonline.com.au/story/3575172/danes-in-60m-qld-cattle-play/ http://www.abc.net.au/news/rural/2018-08-12/defying-and-overcoming-the-nsw-qld-drought/10084358 You might also want to look at the results of the Australian government funding the fencing & water for cattle in each paddock infrastructure in 1 million hectares of land that was running off waste onto the Great Barrier Reef https://youtu.be/oPLXsqS9SSc?list=PL1mdVN1WPaRkJ7K-1vi2VTLfyL2Z9W7zF compared to the results of actions taken to deal with sugarcane run off in the same area. http://www.abc.net.au/news/2018-10-11/laws-not-stopping-fertilser-runoff-to-reef/10348718 Holistic grazing has worked & stopped all cattle farm run off (and increased efficiency & profit for all the farmers involved), but sugarcane is still polluting the reef & strategies completely failed. _"Savory's hostility to mainstream research "_ He's not hostile to mainstream research, he's hostile to non-scientific research designed to make his system fail. The sources saying as you do here are claiming the process is unscientific because it cannot be replicated in all areas & all conditions, but no legitimate research would EVER try to do something so unscientific! If weather conditions change, properly conducted scientific research takes that into account! The "research" you are talking about that he is "hostile" to expects to be able to take a patch of 10 hectares of land in 10 different locations in the world & put a set number of cows onto that land in a set number of paddocks & move them at pre-decided intervals, such as every day at 8am, for a 1 year period & says that if his system does not work under those conditions, then it is proven to be anecdotal & unscientific. I challenge you to put a group of cows into a standard grazing system under those conditions & show it works! It will fail miserably! You cannot take a 10 hectare area of land in New Mexico, Siberia, Brazil, Scotland, Spain, the Gobi desert, New Zealand etc etc & leave them there for a year, ignoring changes in temperature, rain, wind etc & expect to see results as to how many cows can be grazed in that block of land replicated in all those test plots! It's ridiculous to suggest & Savory has every right to get angry when people try to claim his system is a failure because it can't perform consistently between Siberia's winter & New Mexico's summer! the reality is that holistic grazing IS restoring land & it can scale up & match weight gain per hectare seen in factory farm settings when the same quality of land used to grow the crops to feed those animals is used for holistic grazing. That makes him very powerful enemies on BOTH sides! All those that benefit from factory farming systems stand to lose everything! The big chemical companies & big phama lose the lot! & the vegans lose teh vast majority of the public, as it's only factory farming that gets them support! The style of farming seen in the "running out of time" documentary on Savory does NOT outrage people enough to go vegan, they are very happy to eat meat from that type of system, happier to eat that than monoculture crops! So there IS a lot of money involved in crushing belief in this system, that's reality! Despite that, farmers are hearing about it more & more & are adopting it, because like it or not, admit it or not, it simply does work! It's impossible to ignore that the Serengeti IS a functional eco-system with a million large ruminants in it & plenty of grass to feed them all year round. There's no "unproven" in this. _"no single approach is going to work in all conditions."_ This is being recommended for the world's natural grasslands, all 5 billion hectares of them, that's ample land for all the meat we could possibly want to eat now & well into the future. There's no need for it to work beyond that eco-system, there's no need, other than politics, for us to be raising beef cattle in particular anywhere else in the world. Dairy may have some needs in other locations, but beef, lamb, goat etc don't, so it doesn't matter if it doesn't work anywhere else. Now yes it does work so well that people are taking it beyond that eco-system & are also making modification to it to make it work even better in a wider range of environments, but he's only recommending it for the restoration of natural grasslands, he shows that on his map. _"For example in Scotland"_ not a grassland, so not covered by this. Now yes, a variation of this is going to be more effective than traditional grazing if people decide they want to use that land for food production & clearly cannot use it for crop production, but this system cannot make grass grow through snow or sub-zero temperatures, so it's always going to be seriously limited in that environment, as that is not the native environment of cattle. It's effectiveness there is irrelevant as to if holistic grazing works as Savory claims, as he does not claim it is suited to those conditions _"And despite your claim - the article contains no evidence"_ I never said it did! I said there IS ample evidence, not that it was located in that particular article! I suggest looking at some of the research of people like Dr Christine Jones, a soil scientist that has investigated the effectiveness of holistic grazing in soil carbon sequestration, or even just look at the figures on the wiki page for C4 plants (grasses) to start to get an idea of the amount of sequestration potential possible here. 23% of terrestrial carbon sequestration comes from just 5% of terrestrial bio-mass - C4 plants, which are predominately grasses in the grassland eco-systems we are talking about here. C3 plants (including ALL trees) make up the other 95% of the earth's terrestrial bio-mass, but are only responsible for 77% of the carbon sequestration. Savory is saying grasslands can sequester an additional 0.5% carbon into the soil each year. Science says that 1% soil carbon in the top 30cms of soil is 100 tonnes of CO2 per hectare (holistic grazing btw is proven to be sequestering down to 1 metre into the soil, although most is still within that top 30cms that's tested when testing is done). These numbers, when you calculate them out further come in at only a couple of tablespoons of carbon per square metre needing to be added to the soil each year to result in well over the numbers he claims are possible when 2.5 billion hectares are put into play for 10 years like he claims is needed to reverse climate change. Are you really questioning that even just in manure coming out of the animal & being transported into the soil by dungbeetles, that there is not enough carbon in play to provide a couple of tablespoons carbon per metre each year? That's even before we talk about roots & decaying grass. We're not counting the growing grass, as that is not properly stored & is not in serious discussion in terms of carbon numbers, it must make it into the soil before it can be considered as sequestered & removed from the active carbon cycle. Anyway I can give you more links for evidence on this one if you want them, but it's actually a wide discussion, with lots of elements to be considered, so you'll need to give me more details on exactly which part you are questioning if you want me to link you to appropriate sources to address your concerns, but probably better if you do the base research yourself first anyway because I doubt you will just blindly believe anything I tell you, which is good, people should question. That's how I became such a believer in & supporter of this system, I saw this video & thought scam! & went about debunking it & the more I tried, the more convinced I became that it really did work. I did steer clear of pro-vegan propaganda in my research though. If you want an overview of carbon in this system, Tony Lovell's Dubbo TedX talk has a lot of interesting carbon info in it, both for this system & also how it works in the world in general, eg did you know the deciduous boreal forests cycle 7ppm carbon per year? Lots of interesting stuff in that talk
Tullochgorum (20 дней назад)
+Lilac Lizard Well, your rebuttal comes from a site devoted to promoting libertarian approaches to the environment and is pretty long on political invective and pretty short on evidence. It's also by an author who believes that anthropogenic climate change is a trumped up liberal Trojan Horse, so I'm not going to take him too seriously. But the article does contain some anecdotal reports that suggest Savory's approach may work in certain conditions. Savory's hostility to mainstream research does him no favours, and the best you can say is that the benefits are currently unproven. I suspect that the real answer is complex, and no single approach is going to work in all conditions. What is clearly needed is far more research to determine what works best in what environment. For example in Scotland, where great tracts of the Highlands have been desertified by overgrazing, simply putting up fencing to exclude ungulates leads to rapid and dramatic regeneration. http://wild10.org/wp-content/uploads/2013/12/FeatherstoneAlanWatson_WILD10_5Oct_Session2-7.pdf So it's clearly a question of horses (or cows?) for courses. And despite your claim - the article contains no evidence to rebut the accusation that Savory is hugely overestimating the potential contribution of grassland to sequester CO2 and reverse climate change.

I sugest you research Koppen climate classifications & C3 & C4 plants. Trees are ALL c3 & c3 photosynthesis cannot occur in hot areas with little water. No-one is growing forests in deserts or semi-desert land, there is a reason those areas are natural grasslands with C4 grasses as their primary cover - they are the only plants capable of growing in those conditions! C4 plants (grasses) also sequester far more carbon than C3 plants, so even if it worked it would be inferior in that regard, not to mention it would destroy the habitat of thousands of grassland species! Where are you going to send the zebras when you kill all their grasses with forests? You also might want to not so blindly believe Chinese propaganda videos! https://theconversation.com/chinas-desertification-is-causing-trouble-across-asia-59417 "Despite extraordinary efforts by the government to reduce the rate of erosion, culminating in the largest reforestation project ever undertaken, the government itself conceded in 2011 that the “desertification trend has not fundamentally reversed”."

"We know that desertification is caused by livestock." "Almost everybody knows this, from nobel laureats to golf caddies." I hate when global warmers do this. There are other causes of desertification. I have a B,Sc. with majors in physics, geophysics, and math and I am not a nobel laureate or a golf caddy, however I know there are many other factors that cause desertification. It would have been much more honest to say livestock can cause desertification. I like my meat. He then goes on to state that we don't know what causes desertification. I like this talk though since he says we need to be smarter about things that we do, such as husbandry, and he does present solutions. China is now reclaiming deserts also.

I really wish China would use this, especially since they have a growing appetite for beef, it would fit with that perfectly! However their desert management is far more about politics than real management, they want the local herder cultures destroyed & everyone assimilated into government serving sheep status. Maybe once they've done that they might replace the local herders with some mega-farms of livestock & use this

Percibo que estamos en un mometo de transición importante, estan cambiando cosas. Me resulta inquietante del video, que al parecer el sistema que promociona savory, favorece o requiere tambien, la concentración de la producción animal.

So what he said is, each year in Africa alone, the burning is emitting more harmful carbon emissions than 6,000,000,000,000 cars per year. There are only 1,200,000,000 car drivers on the planet, and only a portion of them are driving at any given time. Yet "they" will still try to tell you that my V8 is responsible for "global warming".

such brilliant ideas...is anyone who can actually take concrete steps (governments and other powerful people) even listening?
Lilac Lizard (21 день назад)
Yes. Not enough, but in Australia it's had quite a lot of support in the form of government subsidies to convert in eco-sensitive areas, fingers crossed when we get a drought recovery package to farmers that it's going to include significant increases to support expansion of this to far more farmers. Most organic certifiers are also incorporating into their rules stocking densities that give large bonuses to anyone using rotational grazing, in order to apply pressure to all their producers to switch. The most effective concrete steps possible right now are increased demand for grass fed meat. When that happens, switches follow, as this is just the most profitable way to produce grass fed meat, as well as increasing production possible on any given land space & therefore meeting increased consumer demand for grass fed most efficiently & profitably

So someone should take cows from all the factories. Instead of eating them. Let then go be wild and heal the land.
Lilac Lizard (21 день назад)
Someone should take all the cows from the factories & put them into this without question, but they can't just be left to go wild or they just overgraze & make it worse! They must be forced to remain in a tight herd at all times, so that they manure everything & must keep moving. That can be done with human herders, with fences & daily moves, or with natural predators on the land that grab babies from the outside of the herd for dinner regularly. Which option do you like most?

Lilac Lizard (21 день назад)
Your petition address has gone missing. Are you trying to stop it because you're vegan & want to stop everything, or are you good with replacing chickens with cows raised in holistic grazing & filling those chicken barns with free ranging crickets & other non-sentient insects for food instead? If the latter I'll sign & wish you all the best & think it's an important cause that's lost in vegan extremism, if the former, count me out. If you don't know, in less extreme weather conditions, layer chickens can be incorperated into this system too. The chickens can be housed in a chicken trailer, with nest boxes & perches & each night when they go to sleep, the doors get locked to keep them safe, then the trailer is moved to the next paddock, 3-4 days behind the cows at all times. Come morning, the doors are opened & the chickens can go out & enjoy a new location, with fresh bugs & maggots in the manure to feed on, along with sprouting seeds from the earlier cows. It's a genuinely viable way to produce massive numbers of eggs in genuine free range settings, since it's using the same space as cows, so they can have huge areas each without cost issues to raise them. Would match perfectly with a dairy set up designed to operate to holistic grazing, with a roadway down the middle & long thin paddocks on either side of it & the milking shed in the middle. Add an egg sorting shed into that & not much else is needed. Could easily operate at the organic standard stocking ratios of 2,500 chickens per hectare while mass producing eggs for humans, just by doing the same thing on all dairy farms. Won't work with meat chickens, because as I'm sure you know, they're forced to grow so fast that their poor bodies can't cope & they can barely move around :(

The emissions are actually part of the natural carbon cycle, methane & CO2 are emitted as organic matte decomposes, doesn't matter if that's in a cow's rumen, landfill, or by burning, the same gasses are released & they're just the gasses that were absorbed from the air by the plants a few weeks earlier. Only fossil fuel related methane actually registers in ice cores or other testing, ruminant numbers don't It's also possible to work in from the edges so that extra feed isn't needed to get started & obviously once in operation no extra feed is needed :)

Good talk but a bit deliberately deceitful really Most crops are literally "starving" for more CO2 as the current levels are some of the lowest in the planets history Even NASA who relies on perpetuating the myth of anthropological global warming has from its own data shown that as CO2 increases the amount of greenery on earth INCREASES despite urbanisation and deforestation  at increasing rates The more CO2 in the air the more plants and animals thrive, that's a fact these climate alarmists "conveniently" (Read deliberately) omit from their lies If we want to slow down "natural" desertification we need to firstly stop building dams as they are one of the main caused of land becoming barren and water running off into the sea instead of sinking into the water table Then we need MORE CO2 in the air so that plant life growth increases, crop yields increase and crop durations decrease Less Co2 will speed up desertification nor slow it down, and I am pretty much sure 100% this lying SOS knows that full well but is putting his bank balance above telling the truth
Lilac Lizard (20 дней назад)
​+Mike Mckay _"CO2 being pumped into greenhouses causing crops to mature not only faster but with much higher yields"_ and how did I know that was what you were really referring to lol the pumping CO2 into climate controlled greenhouses during the day, then back out again at night & when the crop is ready to fruit/flower, since keeping the levels high during fruiting/flowering delays the time until they mature & causes mutations. Yeh, not really the same as the real world when you can pump it in & OUT is it! They also pump the extra heat retained by the CO2 OUT! That is the problem in farmcrops on earth! They have no-where to pump the heat out & a couple of degrees temperature increase has FAR more impact on growth rate than any amount of CO2 does! You should know that with all your cannabis research that you're pretending applies to the real world! You should know that CO2 should ONLY be added AFTER temperature, nutrient & lighting have been achieved at optimum & otherwise, the above 3 will have FAR more impact on growth than CO2 will! I guess you're just reading the weed boards but not actually trying it or achieving any practical experience yourself to actually understand it aren't you! _"why isn't that magical wonderful technology working in Australia when it seems to be working in some of the most deserlet areas of the world"_ because Australia was already hot & only growing winter crops. The areas of the world you are talking about were growing only summer crops & too cold to grow crops in winter, so they have space to expand as the planet heats, Australia does not. In fact most of the areas you are talking about that are naturally greening were too cold to grow anything year round, while areas just below them that had good summer growth & winter dormancy are now dying due to no winter dormancy & so bug attacks. The limited areas of Australia that have irrigation are yielding higher per hectare, same as the rest of the world, but the total usable hectares of farmland decreases every year as climate change occurs & prime cropland becomes more & more marginal as less & less rain falls & temperature records break every single month _"Monsanto, they present a far greater threat to planetary food yields"_ and yet you act in a way that allows them to thrive :S _"(assuming they have water)"_ and that's the issue you are ignoring! Outside your climate controlled greenhouses filled with their CO2, climate change is causing less rain & more evaporation over most of the world's farmland. It is also causing more erratic weather patterns, so when that rain does fall, it's in the form of hurricanes or other mass rain events that flood the land instead of intermittent moderate level & therefore useful rain _" tree planting projects"_ You didn't read Sir Sydney Camm's great link did you! It's C4 grasses we need to be planting not trees, trees cannot cope with higher temperatures that are coming with climate change & they barely sequester any carbon anyway. Quite funny teh way you're in such denial of climate change, yet spouting the talking points of those most supportive of it. What exactly is your problem with the system being promoted in this video? Did you even watch it? I'm thinking probably not, you probably just typed "climate change" into youtube's search function & starting ranting on every video that came up without even watching! Jump to 15:00 in this video & see what's actually being proposed here. Even if you don't want to support climate change, this video is still saying things you SHOULD want to support! _"we live in a closed ecosystem"_ same as Venus, which is believed to have once been very earth like, possibly even the origins of multi-celled life on earth & look what happened to it when too much of that CO2 was pulled out of the ground at once! It has the same quantities of carbon & oxygen as earth has in it's "closed eco-system" which isn't very eco-system like anymore due to climate change is it! _"we would be far better off just creating forests"_ no, you would be better off watching this video! Alan Savory is saying that by increasing the number of cows on the planet, but pulling them out of feedlots & instead putting them onto desertifying land & managing them properly, by moving them each day, like they did in the time you are talking about, that if we do that, pull millions of people off food aid, by providing them with a viable source of food through the raising of cattle so they can be self-sufficent, that without changing fossil fuel use in anyway, we can return CO2 levels to pre-industrial within 10 years with only 50% of the world's natural grasslands put into proper grazing management & food production. So how about you stop with the vegans "plant trees" rantings & look at the genuine option being presented here, that can completely solve this problem with no taxes of funding for left wing groups Here's a link I think you'll love www.rightwaytobegreen.com/2017/07/06/fake-green-fake-science-the-sierra-club-doesnt-add-up/ it doesn't believe in man-made climate change either, but it is supporting the system this video is about & it's discussing why the environmental groups won't, due to all the funding they get, with lots of numbers as to just how much the climate change mitigation industry is worth, with billions & billions of dollars in assets & annual donations to many of the not for profits planting trees & locking up valuable land & actually destroying it instead of using it for food production. The solution to climate change is to eat more beef. That's the truth! That's all that's needed to turn it around! The rest of the money is being wasted! (only other project that would be worth considering is mass bio-char of dead organic matter such as forest leaf litter. Turning dead bio-matter into charcoal & dumping it into the ground locks the carbon into solid form for 1000+ years & the soil currently holds more than double the carbon in the atmosphere & every living plant & animal on the planet combined & has the ability to hold FAR more! Savory wants to achieve just a 5% increase in soil carbon in half the world's grasslands. That's all that's needed to fully replace all the fossil fuel carbon we've extracted from the planet in the last 200 years
Mike Mckay (20 дней назад)
Its a bit disingenuous to try and claim that despite CO2 being pumped into greenhouses causing crops to mature not only faster but with much higher yields that it somehow magically doesn't have any effect when a crop is outside of a greenhouse lol Yes farming practises have improved, but so have Co2 levels. So the far more logical conclusion is that both factors are increasing crop yields to varying amounts dependant on how much farming techniques and technology has improved per area on a case by case basis Trying to claim that a country plagued by droughts somehow "proves" CO2 increases don't affect crop yields is similarly disingenuous as NOTHING grows without water irrespective of the CO2 levels in the same way that prehistoric levels of CO2 in the air above a desert wont create trees that are 5 times thicker around the trunk than found elsewhere on earth with the current CO2 levels In fact if the increase is purely die to farming techniques with Co2 making no difference despite empirical evidence to the contrary why isn't that magical wonderful technology working in Australia when it seems to be working in some of the most deserlet areas of the world EXCEPT there? Doesn't the scientific community like Australians or something? That they would be helping some of the driest areas on earth to increase crop yields yet are apparently it seems denying such advances to Australia? Although based on some Australians I have met that's not beyond the scope of possibilities :)  As for the demon spawn company Monsanto, they present a far greater threat to planetary food yields than any miniscule increase in CO2 levels for a variety of reasons and left unchecked will eventually lead to the eradication of all non GM plant strains The fact remains that plants (assuming they have water) do better with HIGHER levels of CO2, same applies to animals too but to a lesser extent, and even NASA who is one of the biggest AGW propaganda sources out there due to their survival being quite closely tied to the AGW scaremongering have had to admit that from satellite data the planet has been steadily greening overall despite the opposite occurring in "some" areas which is at the end of the day "weather" not climate otherwise we would see greenery reducing GLOBALLY not just locally and would therefore see a net reduction in greenery overall not an increase More than enough "actual "climatologists (real ones, not the interns and office workers who make up the bulk of the IPCC signatories) have stated the claims being made by the scaremongers are baseless and exaggerated, which has been proven decade after decade by reality not even closely resembling the doom and gloom predictions we have been duped with to justify erroneous taxation that doesn't even have the slightest chance of making a difference even if the alarmists are correct In fact the absolute best option by far, but one that barely gets a mention or any global governmental impetus would be massive irrigation and tree planting projects globally allowing the planet to sink as much carbon as it could in prehistoric periods when most of the planet was covered in forest and which is where the NATURAL CO2 being released now from fossil fuels originated from Because that's the snippet often missed or deliberately avoided in such discussions, we live in a closed ecosystem, CO2 doesn't magically fall from space and form into oil. Most of the CO2 we "can" release into the carbon cycle was originally part OF the planets carbon cycle and was locked in plants and animals which were present in far higher quantities than we have today So rather than causing immense levels of global poverty and immense amounts of death as a result of said poverty to squeeze ridiculous amounts of tax from populations that doesn't even have any real chance of changing the temperature by more than a fraction of a degree over 100 years whether mankind contributes to the natural warming that is underway or not we would be far better off just creating forests in far greater amounts than we chop them down and stopping dam building projects in favour of irrigation projects to reverse the effects of dams on the surface soil and underground aquafers and water table levels thereby reducing rainwater run off But governments prefer taking money to spending it as the later doesn't fund fancy hotel stays and champagne breakfasts for the ever growing army of bureaucrats the AGW gravy train is creating

+Mike Mckay _"crop yields per hectare have increased "_ This has nothing to do with CO2, it's to do with improved farming methods _" even in more backwards areas where farming methods haven't changed in centuries"_ sorry to disappoint you, but some of those "backward" areas have some of the most advancements happening. If the area is being studied, it's because someone's going in to measure it & those people are generally the NGO's, who are going in & teaching illiterate farmers techniques to improve yields, often also giving them access to better seeds & fertilisers & equipment like bulldozers to better prep land for farming. The stats you are trying to use monsanto also tried to use to prove that GMO was increasing yield. This was countered by stats from Europe showing increases there, along with discussions as to what the changes that lead to the increased yield had been. If you want to see climate change related yields, look at Australia, as Australia, being a dry country is on the forefront. You will see that as a general rule, yields are dropping & land being cultivated is also dropping, due to climate change related drought destroying farm land _"the amount of land with vegetation on it has been increasing"_ it's increasing in permafrost areas (which is NOT a good thing) & like I said, decreasing in areas like Australia & Africa too _"Dams create a stagnant pool of water"_ or what depth you need to explain before you go on _"which the suns UV then blasts killing off vital micro organisms that feed the soil."_ how deep does that UV radiation penetrate into that water? Yeh you're theory gets crushed at that point doesn't it! _"Which is why much of the desertification that is observed happens down river from dams."_ um no, desertification, if it happens down river of dams is because water is no longer flowing down the river at the required amounts, also because it's no longer spilling out onto flood plains to give them the nutrients picked up upriver. Nothing to do with microbes being killed by sunlight _"paving the way for even more dams to need to be built"_ Pumped Hydroelectric Storage maybe, but that's not the same as the dams you are talking about

+Sir Sydney Camm You're patient lol to type all that in response to the comment that was made :) That link you gave is awesome though! Is the simplest explanation I've ever seen for C3 & C4. Pity it leaves out sorghum & millet when listing c4 plants though, those are 2 very drought tolerant plants that make up major parts of diets in a lot of the world & that we should be looking at more as far as increasing, even to replace corn potentially, due to it's water hungry needs compared to them (edit, I wrote the below, having misread & thinking you were against dams, but if you don't know about it, what I wrote is probably still relevant anyway, but reading right, I think more than likely you already know about this stuff) On the dams, you seem like the sort of person genuinely interested in learning on these subjects, so may I suggest having a look at this system https://www.youtube.com/watch?v=-4OBcRHX1Bc&index=10&list=PL1mdVN1WPaRkJ7K-1vi2VTLfyL2Z9W7zF&t=276s similar to what beavers do, basicly making low level leaky dams & has the complete opposite effect to traditional ones, especially since that system isn't for draining water from the river system to take to other locations, just slowing it entering the river, so it keeps the surrounding soil in better condition. holistic grazing alone has a big impact on that, making the soil "soggy" as all those roots & mulch retain the water & slow it's flow, but coupled with NSF, it can do even more for the environment :)

Thank you Lilac Lizard for your eye opening criticism of my post. I will have to take a good look at the material you have given me. Patrick
Lilac Lizard (21 день назад)
+Patrick Lincoln _""Holistic management does not permit replication,""_ This is an oversimplification. What he should have said is that nature isn't replicable, therefore systems must adjust to nature's lack of replicability. If you set up a holistic grazing area in biosphere 2, you could run it year after year after year with an identical system (except that over time you would still end up with more carbon in the soil & this would increase the number of animals needed to eat all the grass, but it would be pretty close to the same & you could get clear scientific results from it) The reality is that no farmer grazes in an identical way year after year & that no 2 locations use identical grazing numbers. You cannot fence off a scientific test 1 hectare area & put the same number of cows in each one year round for 10 years in England, Siberia, New Mexico, Canada, Saudi Arabia, Syria, Brazil, South Africa, Fiji, the Australian outback & New Zealand. That's not how science works! Anyone who proposed such a study would be laughed out of any scientific establishment, yet all the criticism you are finding directed at Savory is asking him to do exactly as above. It's not surprising he would get angry being asked to do this, ANYONE familiar with scientific processes would! Here's a discussion about what the key principals that must be followed are & how the studies that showed the system not to work failed to follow them. Note that there are PLENTY of real world science experiments going on out there & the rules here are quite consistent with how countless studies operate, when faced with uncontrollable variables impacting the tests https://www.tropicalgrasslands.asn.au/Tropical%20Grasslands%20Journal%20archive/PDFs/Vol_34_2000/Vol_34_03-04_00_pp207_218.pdf _"All you have to do is perform the experiment on random plots of land in a double blind study with rules of thumb for holistic grazing and see how the results turn out."_ could you please clarify how you're going to run that double blind part here. I know that double blind is good, but in some cases it's just not possible to use. A good example of that would be diets. There's some studies in progress at the moment as to whether fast or slow weight loss is best. You can't double blind study that can you! Therefore, the appropriate scientific strategy for that scenario is NOT double blind, but rather "randomly selected" where participants volunteer for the study & are then randomly chosen to be put onto either a fast weight loss program or a slow weight loss program. I would suggest that that model could be used here, but double blind could not. If you think double blind could be used, please detail how. There are large numbers of farmers out there that have chosen to convert a part of their farm to this, while retaining the rest as is, converting say 1/3rd that is either randomly selected, or is selected because it is the worst land & therefore least problematic if it doesn't work. These are generational farmers, so they know the conditions well & know well what will happen to said land if it remains in the same system as the rest of the farm, but it's also run as a separate area next to the rest of the land, so all round I would say that provides easy high quality testing wouldn't you? If not, what would you change to make it better? Farmers who have done this, consistently switch their entire farm, normally much earlier than they intended to stop the testing. In many cases they need funding to add new fences & water for cattle in each new paddock & this has been one of the reasons they didn't do the whole farm at once anyway, but commonly they then take photos to the bank & take out a loan to obtain the infrastructure for full conversion because they are SO impressed with the results they have seen, as are their bank managers! There's also other measures of success that can be used, such as water quality measurements downstream of this system's application. The Australian government funded the infrastructure to switch over 1 million hectares of land in the Great Barrier Reef run off zone, due to consistent evidence from other river systems showing that switching to holistic grazing was resolving issues. The Great Barrier Reef is now free of manure & cattle farm run off, but still dealing with serious chemical fertiliser run off issues, due to the different measures used there to try to curb that failing after years of implementation. There has been no failing of any holistic grazing system a decade later, no farmers have converted back or found it to not work, all are VERY happy with their increased productivity. There's no new people in to test if they will continue applying it/have the ability to use this system, because the results have been so positive that it has stopped the farm exodus that has been happening in much of the country & much of the world. In fact many of the farmers in that system have purchased additional farms outside that region & converted them to holistic grazing with the profits made from their original farms. If a farm did become available in that area, it would be instantly snapped up by the neighbour, so we're never going to see new person in testing Here's a rebuttal to that sierra club article you are using www.rightwaytobegreen.com/2017/07/06/fake-green-fake-science-the-sierra-club-doesnt-add-up/ there's a link on it as well to a test carried out on a mine tailing site. I would have liked to have seen them do that as a scientific control, leaving half with no cattle, but I guess it had already been sitting there like that for so many years anyway that they probably felt there really wasn't a need, so that's another variation for you, instead of using standard paddock systems v holistic grazing, that's using no livestock v holistic grazing. Elements of the system can be extracted & tested separately too, as was done here https://www.sciencedirect.com/science/article/pii/S1470160X15006299 "High impact grazing as a management tool to optimize biomass growth in northern Argentinean grassland" & as you can see, what they found supports savory's claim that holistic grazing will reduce old, dead matter & crush it into mulch. You'll find that for most scientific testing, they won't use the term "holistic grazing" but rather "intensive managed rotational grazing", "mob grazing" or a range of others, like above, but mostly the first above, sometimes with a word missing or changed in order, all the same thing though & shown over & over again that if the principals of 1 Control rest to suit growth rate of plants 2.STOCKING RATE is adjusted to match CARRYING CAPACITY. 3. PLAN, MONITOR and MANAGE GRAZING. 4.Use short graze periods to increase animal performance 5.APPLY MAXIMUM STOCK DENSITY for minimum time. 6.MANAGE FOR BIODIVERSITY TO IMPROVE ECOSYSTEM SERVICES. 7. Use large mob size to encourage herding (sorry about the caps, copy & paste) are followed, then results are consistently better than stagnant paddock systems ie more diversity & bio-mass & more weight gain or more animals able to be housed on the same land area as in stagnant systems Here's some more evidence supporting it for you too http://www.regenerateland.com/evidence-supporting-holistic-management/

+Sir Sydney Camm: No, I have not read his website. Are you on the fences with respect to Savory's claims at this point? Look. The way I see it the matter is simple. When scientists go to ask the man to document his work, explain how to make it replicable, he doesn't help on this regard, instead he insists that holistic grazing is by nature not replicable. That is a total copout and a good way to hide non results or bad results. I would be more inclined to give Savory the benefit of the doubt if he instead cooperated and said. "I need help making this well defined so that we can see if replicability is possible". Everything does not need to turn out exactly the same everytime. All you have to do is perform the experiment on random plots of land in a double blind study with rules of thumb for holistic grazing and see how the results turn out. Even if it is not identical everytime and dependent on the circumstances, there must exist some way of putting in writing what is expected and that which is expected makes it well defined enough for a scientific study/test. This is so far from science that I don't need to look further to Sierra Club investigations. Savory is anti science to the core.

+Patrick Lincoln He may well have a good reputation, he may well report well on other topics, he may well be vegan, but fulfilling your claim Savory is bullshit, he does not. The Sierra Club looks a promising counter. Monbiot could have just said 'Sierra Club investigations' but he didn't. It is full of the problem of defining what is overgrazing, holistic or planned grazing, etc and it indicates he and Savory don't really know the words the other is using. I wouldn't read too much into the direct quote you used. The surrounding text shows Savory is tired of scientists trying to gainsay by demanding precision on one place to find fault it can't be exactly replicated on another and therefore dismiss the entire approach and the quote is more the day has dragged and time for the Sierra Club to take a break. Looking at Savory's other videos talking to ranchers, he's not an easy guy to talk to, bit blunt and brusque, old soldier manners type, like a lot of white folk from Southern Africa. It's probably rubbed the Sierra Club up the wrong way. SC quotes the idea has failed everywhere but it hinges on what is 'overgrazing' and 'rest' meaning to either side. And then with the usual power of he who writes the article, he concludes that all the world's experts say and claim Savory is wrong. End of. Tad unfair...why not name another institution or two of Sierra Club stature and finish Savory off? Anyway, the world's always sceptical of new things and usefully so but Monbiot as the nail in Savory's coffin? Nah. Note that I haven't claimed to be an acolyte. Have you read Savory's website?

George Manbiot has a very good reputation as a reporter. I can understand that you are skeptical because he has turned near vegan. But maybe you should preach what you are asking me to do "find Manbiots sources"...or maybe something else that is just as good...other sources. I found this text in an article by someone who went out to interview the Allan Savory.... "The telephone rang, and Savory stood to take the call. I studied an informational sheet he had handed me when we met. It explained why he couldn't talk about the science behind his methodology. "Holistic management does not permit replication," said the document, which Savory had authored. "This point is critical to understanding the great difficulty reductionist scientists are experiencing trying to comprehend holistic planned grazing—because no two plans are ever the same even on the same property two years running." A stunning admission appeared a few lines lower: "Every study of holistic planned grazing that has been done has provided results that are rejected by range scientists because there was no replication!" And with that I rest my case. Here is the source https://www.sierraclub.org/sierra/2017-2-march-april/feature/allan-savory-says-more-cows-land-will-reverse-climate-change. Replication is how you verify in science, and when statements like that are espoused by Mr. Savory, you can bet that it makes a lot more sense to take Mr. Manbiot at his word for the things he said. This means that Mr. Savory's claims are very likely bogus and that Mr. Manbiot was on good grounds when he said what he said at 16:00. This was not a misunderstanding on Mr. Manbiots part. Savory is just wrong. If results are not replicable, then he could just as well be making up stories with fake before and after pictures to protect the beef industry (I really don't know what his motivations are though).

Human beings produce Carbon Dioxide every single time they EXHALE ( which plants surely appreciate since they build their food from  it ). I think that in order to be consistent with their warped ideology Bernie Sanders,  Al Gore, Arnold Schwarzenegger  and other Climate Changers like them should stop the  practice of BREATHING immediately. At the very least,  Leftist politicians and celebrities should limit their flights to once per year to avoid looking like hypocrites. I've only flown in a jet twice in the last 10 years, and I'm a Global Warming SKEPTIC .  Guess what? There's this great new technology called TELE-CONFERENCING which doesn't produce any plant-food  ( I mean CO2) at all. Look into it, Bernie.

this is basic knowledge. that animals must live with vegetation to live in harmony sustains life. its greed that have created the destruction of life. we have always known that forests sustained themseves as long as we did not burn down the forest even if we didn't understand the connection between animal and plant. algea actually break down organic material like meat and use it to grow more algea that turns into soil when the algea dies. if you feed a dead chicken to algea, the organism will slowly eat the dead chicken by growing on it but need water. animals also need water. we have seen in rain seasons of some places in africa in many examples that show massive regrowt of land by heavy rainfall. this have worked in conditions of little lifestock to support it. seeds only need minerals, water and sand and light to grow grass as carbon is taken out of the air. the efficient way to reclaim land with vegitation is not lifestock but machines that takes vapor out of the air and collect water. in order to run these machines we need a energy soruce like solar panels. the soil of the land is often to hot to sustain plant life and will make collected water evaporate back into the atmosphere. to prevent this we could for example use solar panels as energy collectors and water the land underneath them so that they can cast a shadow on the land and keep the temperature down. by making solar humidity collector crops like im saying, we can give the land the water it needs to sustain grass growt and trees or just crops. eventually the water collectors will have exess water left as the soil can not absorb any more water and water can this way be distributed to people as water supply as a addition to supply the soil.

A person who can "research" and say that we suddenly have too many elephants after thousands of years of their existence is a moron - no matter how humbly he puts it to accept his unforgivable mistake. He does not belong in the world of science any longer. He should be in jail, 1 year for each elephant he caused to die.
