Greg Asner: Ecology from the air
Вставка
- Опубліковано 28 чер 2024
- What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail -- what he calls "a very high-tech accounting system" of carbon. In this fascinating talk, Asner gives a clear message: To save our ecosystems, we need more data, gathered in new ways.

Who cares about Ironman and Thor and Superman, this guy is the kind of superhero we really need!
...or both
This is one of the finest technologies ever applied in the area of mapping our environment. Most probably this is easiest and cost-effective solution which gives in-depth info. Kudos to Greg Asner's mission of mapping the world. I hope the world leaders sit and take notice of this kind of technologies to save our lonely planet. Highly recommended.
Greg,
Congratulations on TEDtalking your work. From lions and elephants to 3D mapping the carbon stock of vast regions of the planet, your talk is fascinating and brings the value of science into context for all. Your point about the fundamental flaw of designing conservation plans without specific geographically explicit data makes total sense. I share your vision of getting the Carnegie Airborne Observatory's imaging spectrometer and lasers into orbit. Good luck on your work.
Amazing analysis techniques. Keep up the great work :)
Thank you for sharing your work and highlighting the importance of technology in ecological conservation.

as a geographer and recent student,I would love to see this technology in orbit and it be available to us. The possibility of projects on the local scale would be endless and bring great results I am sure of it!
A very interesting video, highlighting a technique with a great potential as a tool for understanding. The only thing that made me wince was the idea that wildlife should centred on "nature reserves". Whilst I get that this is a short-term "bank" for biodiversity, there are still those stubborn island bio-geographic issues that mean sooner or later we have to look at biodiversity in the wider landscape. Ultimately, we need to look closely at our own human numbers, that threaten to overwhelm even the nature reserve areas that we do designate. For example, in the UK, such designated areas are under threat from a government that sees them as getting in the way of economic recovery. There are a plethora of "initiatives" under way that aim to loosen their protection.
Many UK bird species are not habitat-specific, and therefore are not potentially nature reserve specific. They rely on the wider landscape. Consequently such birds are often in decline, especially if they are specialists in that wider landscape. The decline in arable landscape bird species here, is steep and dramatic.
wow, that's amazing
I haven't see imaging spectrometer before and thats an amazing technology than handheld spectrometer👍
It is amazing.I can't Image the research has realized 5 years ago.
Fascinating.
Very impressive!
Hi, I'm in your son's pledge class. I like your talk.
Great to see. I wish I could go in your observatory especially over the Amazon. I think other people would like to, too. It is always good to remember the mass of folks that miss out from a living because some use the laws put. Lets rather work to make it possible for all to make a living but this can only be achieved with a specific type of 'Recognised Communication System' world wide for each area - no I have not been able to tell everyone about this, or get make this yet. But I enjoyed seeing what you have made.
Maybe a company like Google could be interested in putting this technology into our atmosphere, and map the entire world?
Or the military?
Ethan Glover Private ownership only works if preserving the area is beneficial to the owner. What do you think private companies would want to do with the Amazon? They would want to strip it clean.
The area should be depopulated.
Not if I had it.
yeah until they see the effects of that, like flooding, erosion, loss of productivity, soil nutrient loss, well less oxygen of course, rise in CO2 etc. That's what policy makers don't see: the effects of their decisions
B Bernal Not even then. They'd move on to the next area and proceed to strip it clean. They're like locusts.
Awesome technology! :o
Thank you so much for presenting this wonderful research. here It's eye opening indeed. Thanks again.
Kindly bring your shuttle sometime over in Bihar, the place where I work. Maybe we can work collectively.
Thanks
Does he share this data somewhere?
Love what it's being used for here - scared of what it's being used for elsewhere.
in min 9:47, when he mentions illegal mining he says "dont worry, we are working with the authorities to deal with this and many other problems" ... dont worry?? i guess all humans should worry about this, otherwise forest destruction will continue! i dont believe that the authorities make much! i made my PhD with the topic of intentional fires in Amazon rain forest and the authorities used to say, we have it now under control.. however, the satellite images showed the oposite, Brazilian Amazon has more fires now than ever and the size of the fires are bigger than before. If we keep trusting local authorities our Amazon rain forest will soon disapear, so... please let us worry about it and think of strategies to stop illegal fires and mining.
2020 called, the authorities were not working with them.
Excellent.
Chemistry, Physics, Biology.... boring subjects? What!?
what
especially saying that to a room full of chemists, physicists and biologists...
we all have it backwards; we (are forced to) manage the small remaining wilderness areas for biodiversity - instead of managing everything else for biodiversity.
Is this tech of any help for ecosystem restoration ?
Amazing new views of the planet's rainforests, showing both how climate change is affecting them and their inhabitants, and how deforestation is causing climate change. Shame he felt the need to encourage everyone watching his talk to fly to the Amazon and look at it from a boat rather than explore his amazing maps on Google Earth :( Amazing how even scientists in this field don't make the link between the carbon pollution we each create and climate change!
a brilliant idea could convey in interesting Spanish
good good good
Thanks to technology we don't need autumn any more because computers can change the color of tree!
Fund this
We can hopefully infertile using inject able solution for sterilization, if some animal is overpopulated like elephant which might have adverse effect on the ecosystem. But at this moment human overpopulation is the concern. This beast is very difficult to control.
like si hablas español
manage the planet... George Carlin would have something to say about this.
Tadas K. George Carlin was a comedian not a scientist.
oh yeah yeah
I know you hate Farmers for their deplition of ground water but do you know how much the farm backs down on killing old oaks.
He totally had me until he started to jabber about global warming and carbon dioxide. It's a shame such bright and talented people have to say such stupid things in order to get their research funded.
so you don't think climate change is real? or just that his factoid was not accurate?
leo hood Climate change is real , just the fact that us humans are the main reason is wrong .
do you have any evidence to back that up? papers? journals that have printed that anthropogenic climate change isn't fact?
That's the wrong way around. If you say climate change is caused by mankind, you probably have proof for that. Do you have any evidence this is caused by CO2? That the greenhouse effect is real? Is there any global warming at all?
i have a lot of work on at the moment but keep it coming and I'll give you some papers to read over? i'm not a climate scientist I study forestry.
