How to green the world's deserts and reverse climate change | Allan Savory
A climate change talk you dont want to miss

Follow by Email
"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.

JaiUneGuruDeja : Makes me want to buy some dry land and fix it

Light Bulb : terraforming deserts would be 1000x easier than terraforming mars

DiyCraftProject : how am i only hearing this in 2019

Rod Alan Richardson : In the ranching community, I learned about Intensive, rotational grazing since the 1980's. I spent time on several ranches that had experienced similar, land-healing results after implementing these practices.

Sebastian Fernandez : Well now it makes sense why the American Great Plains are desertifying, because we killed all the buffalo which kept the land in shape.

Carlos Ferez : Allan Savory is an admirable genius. A person who recognizes his past mistake, now discovers what can save the world.

M T : I have been making this argument for over a decade. My professors did not want to entertain any idea that was not fossil fuel and carbon commodities centric. Monoculture farming and government controlled eco management is causing far more harm than all the fossil fuels for the past 100 years

Anthony Beers : God Bless you Sir. I'll be looking up your research. -Tony from Zambia.

Alex Polacco : Take this to ELON MUSK. So he can start Terra-forming Planet Earth before he starts on MARS!!!!! Cause we need it HERE 1st..,DONT WE?????

Damion Copeland : In others words nature was doing perfectly fine before we messed with it. Excellent presentation, let's hope we take heed.

Scottish John : I was feeling pretty miserable today until i watched this. What a change from all the misinformation we're usually fed.!!!

Brian Barrow : to admit your wrong is powerful enough to give your life meaning.

Steven Coffey : This was published in 2013. Where do we find an update/progress report?

TeatimeAndy : Amazing presentation, this needs to be shared worldwide!

stephan W : Basically add organic matter To the soil, seems very obvious.

Matty OD : every elected official needs to watch this talk

John Will : When we mix pragmatism, with industriousness and intelligence - we get outcomes like this. Great work. meaningful work.

natureboy tom : I actually did this in high desert. I ended up with 8 feet tomato plants. The place turned tropical highland.

Will Lockwood : Reminds me of the work started by Sir Albert Howard where he recognized how the Indian farmers were able to farm the same land over a millenia.

Malky24 : I'm the US would it not be better to reintroduce bison? They're adapted to the environment, bigger and produce more meat.

南有乔木 : Ant Forest converts sand into green land again by mapping foot step to real trees. I have planted 9 trees in the northwest of China. Every step is a future big step.

tenj00 : Let's spend the future turning deserts into woods instead of bombing the crap out of everything, like we did in the past 100 years!

jn846 : I just saw this today, it's May 17, 2019 - 6 years after this was posted. I'm surprised we have not heard more about this as it seems like it could be a real solution to many of the earth's problems - climate change and food shortage to name the top 2. Seems like it should be required viewing for all climatologists.

mark emilio : Not so fast matey! Water has a flat surface and that's over 70% of the Earth's surface making the globe model an impossibility. Check your facts!

Kat Jasper : It's all fine until they bring up that bogus climate change crap.......that's why they are changing the signs in Americas national parks because their "amazing" predictions of "no glaciers in 2020" were BS -

Joseph Duncun : OMG .......... this is awesome.... WOW ITS ALWAYS THE MOST SIMPLE THING

Random User : This is the kind of person who deserves a Nobel Peace Prize not your presidents and political leaders.

Robert Orrom : Hey Al Gore, please give your Nobel prize to this gentleman

oranges : I'm shocked how many people are responding positively to this lying sociopath.

Find Manny : this is nothing, the real method and most ignored, but well studied, is use of the desi cow in india.The method is just really methods of spreading of manure. ITs like DUHHH to a farmer

RVStudio : Doesn't seems like meat industry lobby?, to promote it own business and the monopoly (concentration) of the production.

TLZ Inc. : I think the Native Americans had it right.

Raze Havoc : Fascinating! The secret is to mimic the herd/predator relationship that kept the herd animals tightly packed together and moving constantly. High numbers of herd animals break up the ground, fertilize the grasses and quickly move on to fresh food allowing the grasses to rebound thicker and more dense. The grasses and the root systems act like a giant sponge holding rainwater long enough for it to soak into the water-table not running off into rivers washing top soil away! This allows a dramatic change to the environment, the water table fills up feeding springs, streams and lakes. The key to restore the grasslands is using natures natural processes of massive moving herds hunted by predators.

Spaghetti man : Wow, this reminds me of liberalism

Mouse Killaz : Science proved that scientists are the main causes of climate change science.

Owen Xu : wait... HE KILLED 40,000 ELEPHANTS?!

Dahvon Colon : Wow this needs to be taught is schools.

Hermanto Dharma Putra : im sory Mr Allan...the chinese have been ahead of you decades in term of desertification and the only nation first to succesfully turning deserts to green pastures...

Jack Flash : Kill two birds with one stone, bring back the land and grow more livestock.. grass fed too. Sounds like a win / win to me.

Martin Sigley : Absolutely amazing.

Andrew Pattison : The UN wants drought struck land

ХОРОШО : Why there is no global program to implement all these findings? Why so many talks about global warming and not doing what this man said?

Marley Butler : Climate change is an oxymoron

MsArgentana : now we are on 2019 but nobody listened to Savory

stephan W : We haven't got a CO2 problem.

BUNTY : Make a macro plan sir it's barely needed otherwise the planet will vanish

Samwisegamgee The Brave : omg what a hero. yay. super doooper.#

David Carbonnel : Why am I not convinced...? Oh and New Zealand is missing from the map... again...

GlassyEyed : I cried at the before and after pictures
