- World Scientists Urge Key Actions for Achieving Food Security in a Changing Climate ccafs.cgiar.org/commission/rep...
To achieve food security in a changing climate, the global community must operate within three limits: the quantity of food that can be produced under a given climate; the quantity needed by a growing and changing population; and the effect of food production on the climate. At present the planet operates outside that safe space, as witnessed by the enormous number of people who are undernourished. If current trends in population growth, diets, crop yields and climate change continue, the world will still be outside this 'safe operating space' in 2050. Humanity must urgently work to enlarge the safe space and also move the planet into the safe space. The Commission on Sustainable Agriculture and Climate Change has a produced a set of concrete policy actions to transform the food system.

why don't we focus on educating everyone to grow food in their own backyard? More self-reliant communities?
max some lit content man
Not efficient. And as a consequence cause for walls and wars.
This is one of the most important challenger that every human has on the planet. Pay attention.
In developing countries like mine, climate change remains the major threat for small scales farmers. By 2050, I don't think if they will be able to produced food to meet their needs.
It's basically a production possibilities frontier, a basic economic model used to show the possible combinations of factors of production that can be achieved in an economy.
Nice
try to share with me for the worldwide media focus
yo this is so true and its scary to think about. love the video by the way
How to download food security data and draw graphs like this...
Any weblinks ...
This is really good and so true, but there is a big obstacle about how people changing their diets and important crop yields could happen in some area not for all. It is not easy to just change diets without nutrition researching.
Thanks for the reply. I know we have been tampering with the genetics of our food crops since the "beginning" but within the bounds of natural biology. the socalled frankencrops is what scares the crap out of me. If what Mendel meant was crop improvement by selective "breeding" while maintaining genetic diversity then that is ok by me.
Lots of information to think about. Talks about problems and solutions. I'm not sure what I can do to fix this situation. Grow my own garden veggies? Last summer's garden was eaten my moles. I wish our leaders will take notice before its too late to fix the problems.
We can change our agriculture by decentralising it.
This video it's an other green revulution, this is not the solution, there is lot of solution the problem is that they make the life hard for small growers to start their own farm. By the way they could grow locally and feed their community, relieving the burden of big mega farms to want to feed the world. Their is not one solution but hundreds of them. The scientist will save the world hunger, I do believe that the scientist have good intention, but in their laboratory they are far from the big picture. Trying to make seeds that resist to pest will never cunterbalance the problems, that will only increase overtime a worst negative feedback. Anyway hopefully we will keep on going and improve our way to relate to nature.
Great info, I would add industry pollution, fuel consumption and some other pollution sources... human must learn to use efficiently natural resources and diminish the overuse of other resources...
Why not put population awareness and birth control here as another very important way to expand the "safe space"?
wow, this is inspiring.
Good video. I particularly like acknowledgement that dietary habits need to change, rather than seeing just a response to demands (e.g more meat) as presently. I'm glad this purely demand driven obsession is now being questioned. I suggest managing populations of plants (or animals) hosts, pathogens, pests be more emphasised rather than 'improved' germplasm strategies that displace remaining diversity in highly variable climates to come. And that traditional systems be studied for solutions.
Safe-space? or existing-space?. I think we nust be stay in the left-down corner of the area as much as possible. Is it?
True I was wondering that, what about all that food waste, if we used that and had better redistribution of the food we already have we could be feeding a lot more people.
Correct. The issue is capitalism
Christian Brothers University natural science major
not every crop genetics refer to transgenic biotechnology... What Mendel did is crop genetics and that is not bad... traditional crop improvement IS crop genetic manipulation... It all depends on how you transform the crop by what means and what purposes you intend... please stop considering crop genetics the same as frankencrops
This gives me hope for humanity.
This is informative. Thank you!
This is a Wonderful video. Thank You. Sadly it's going to take some time still before the masses agree that we human's are the problem, and we all start working together to be the solution. I wonder how the history books will view us. Right now we have at our finger tip access to everything we need to make an informed decision based on facts not and opinion, and yet so many are so terribly uninformed.
Really inspirational. This makes me believe that there is future for humanity.
population is an issue
@sonicmatt93 I believe the same
This video addresses consequences not causes!!!!! A recent United Nations report on how to feed the world in 2050 stated that we would need to invest US$83 billion a year in agriculture to feed the growing population in 2050. The cheapest alternative to this is simple.... voluntary contraception. Fully meeting the need for modern contraceptive services worldwide would cost $9.4 billion and this would include the estimated 225 million women who want to avoid a pregnancy who are not using an effective contraceptive method.. Providing full contraceptive access worldwide would mean unintended pregnancies would drop by 70%, from 74 million to 22 million per year and avoid more of the consequences of an overpopulated Earth including the need for more food and climate change.
So what is the climate changing too?
I'm confused about the definition of safe space. Could someone please explain?
well the safe space is the amount of food versus the growing damand
Wow, these are great. Let's share this video.
Inspiring. :)
I believe it. Smart people have the fewest kids.
This is a good video. Informative and I hope all of us especially the government will watch this.
how can l get this video l have presentation on Argi CC& food sécurity and l wana use it
Don't just adjust SAFE SPACE - round it to unlimited :)
Shared and tweeted.
I enjoyed and I agree. Several actions has to be done in that directions and the NGOs can make the differences. People has to believe they have to make the change not only wait the gov.
Wow, this is inspiring.
Thank you for this education - I didn't realise. My son and I have been vegetarian for 6 weeks now and thriving on our new diet regime :)
Gageons oum walid
wow, this is informative.
Dr Richard Demond Broussard professionally certified SDG academy feed a hungry planet and early childhood development foe sustainable development
I’m glad I won’t be here in 2100 let alone 2060
This is so true.
And a chicken every hour
wow, this is true.
increase crop genetics. okay fine
I whip for humanity
Hope we can make this a reality.
Let us share the vid to make it happen.
Thanks to corporations and corrupt politicians and judges, the political will to do what is necessary before devastation will occurs is too lacking. The only remedy I can see is that people need to take the necessary steps themselves to secure their futures. Our solution is at HORTAQUA.com .
This video inspired me not to eat a moo moo once a week. It inspired me to eat one every day
Or.. we could have less people? Why are we catering for an evergrowing population. Realistically we won't need to make drastic changes to the way we produce, (not that it's not a good idea.) A control of our curve of growth would solve many problems on it own. Not a very popular idea, as most people believe in ther right to have as many children as they please, even if they do not have the means to care for them. In the long run even if all the big corporations of the earth, decided to get all goodie two shoes, evetually the graph will be people... vs the amount of food we can produce to FEED them. Just a thought.
Makes good sense that a finite world supports a finite population. Fortunately, several measures that would reduce future population growth are also good for the people of today, such as education for women in the developing world. If only there were more funding for it...
We can have as many children as we want! We have the technological innovations to grow as much food as we want, and the States are holding on to ALL of them! This includes the air-to-water maker, canned or bottled oxygen, good cleaning aids for the soil, such as gold manna or ormus monoatomic gold and liquid ionic minerals, and even the cleanest soil on earth--the diatomaceous earth.
@Alex Delashmit I'm not thinking about myself. I'm thinking about my country and the world!
THANOS WAS RIGHT
Some countries have already started witnessing a population decline, heck... even China is slowing down rapidly (thanks to the one-child policy era). In about 60-70 years, I think even India will start declining. People not wanting to have kids will be a huge relief for our planet!
And search weird Russian guy dancing for laughs
Lol
I was with him until he mentioned improved crop genetics, which sounds conspicously like genetic manipulation (GM crops) which I am 100% against
Wisful thinking, as long as we don't stop population growth and economic growth. Humanity is in a horrendous overshoot situation. We need to stop growth and start organised contraction, slowing down, demechanisation, relocalisation of production and consumption and return to wortk in the primary sector of food and fibre production, if we want to have a chance to survive on the Post Abundance Downslope. ecoglobe.ch
this video tries to be inspiring and i like that it shows some of the things we need to work on. but the content doesn't make sense on the chart what so ever.
the population increasing to 9 billion when it could be going in the other direction.
All of the answers to those dilemmas the States has in the form of advanced technological innovations, such as the air-to-water maker, the bottled and canned oxygen and UV disinfection robots. They have all the cleaning aids to grow crops, but they're holding them back. Why? Because they don't have any food, which happens because they shit everywhere and allow Ebola to be in the land, sea, and air, which I believe is contributing to climate change. When they hold those technologies back then countries respond likewise by holding on to food stables, such as glass gem corn, palm tree kale, butter coconuts, yams, pink velvet bananas, etc. They're the cause of the food insecurity in the world and for themselves.
Check out tai Lopez on RUclips he inspires me lol
What if u hate vegetables! Sorry world but vegetables are nasty
