Changes in agriculture could cut sector non-CO2 greenhouse gas emissions by up to 50 percent

From Eurekalert

Public Release: 17-Dec-2018

International Institute for Applied Systems Analysis

The agricultural sector is the world’s largest source of non-CO2 greenhouse gas emissions, and IIASA-led research has found that changing agricultural practices and a shift in diet away from meat and dairy products could reduce the sector’s emissions by up to 50% by 2050 compared to a situation without mitigation efforts.

IIASA researcher Stefan Frank led the team which carried out the first detailed analysis of agricultural non-CO2 mitigation using a combination of four different global economic models and assessed the reduction potential. They used the carbon price in the models to estimate the mitigation potential of each option, although Frank stresses that carbon taxes are not considered a likely policy instrument for the agricultural sector in reality.

“We gain insights on the contribution of different mitigation options across regions and identify robust emission reduction strategies both on the supply and demand side,” he says.

Efforts in the agricultural sector alone could reduce up to 15% of agricultural methane and nitrous oxide emissions by 2050, a total of 0.8-1.4 gigatonnes of carbon dioxide equivalent per year (GtCO2e/y), at an already low cost of US$20/t CO2e. Dietary changes in overconsuming countries could contribute additional reductions of 0.6 Gt CO2e/y, a total emissions reduction of 23%.

The researchers used the Global Biosphere Management Model (GLOBIOM), developed at IIASA, and CAPRI, IMAGE, and MAGNET, developed by the University of Bonn, PBL Netherlands Environmental Assessment Agency, and Wageningen University, respectively, to model eight carbon price trajectories ranging from US$20/t CO2e emitted, to US$950/t CO2e by 2050 to estimate the economic emission reduction potential from the sector. This highest figure is thought to be the price needed to meet the 1.5°C climate stabilization target across all sectors of the economy.

At the highest carbon prices of US$950/t CO2e, agriculture could achieve emissions reductions of 3.9 Gt CO2e/y by 2050, 50% lower than the baseline scenario without climate change mitigation efforts.

Methane and nitrous oxide emissions from agriculture currently make up 10-12% of anthropogenic greenhouse gas emissions, and the percentage is growing, largely thanks to the increased use of synthetic fertilizers and growing ruminant herds. Since 1990, emissions have increased by a third, but the data shows that production is up by 70%, so agriculture is becoming more efficient over time. If the world is to meet the 1.5°C climate stabilization target set out under the Paris Agreement, however, these emissions will need to fall.

The beef and dairy industries are highly greenhouse gas intensive, and across all models and carbon price scenarios, had the potential to contribute more than two thirds of the total mitigation potential in agriculture.

Frank and his colleagues identified three areas for mitigation on the supply side – technical options such as animal feed supplements to improve feed digestibility or anaerobic digesters, structural options, which are more fundamental changes to agriculture such as changes to crop and livestock portfolios, and production effects such as changes in production levels. Demand side options involved consumers in developed and emerging countries switching to diets with fewer animal products.

“Steering mitigation action towards a limited number of regions, such as Africa, China, India, and Latin America, and commodities such as beef and milk, which are characterized by relatively high emission intensities, would allow for the realization of substantial emissions savings on the supply side,” says Frank.

The models show that as carbon prices rise, technical and structural options become exhausted, after which emissions reductions can be achieved through reducing production and consumption of greenhouse gas intensive products, such as meat and dairy. Such dietary changes would have an added benefit. As demand drops in overconsuming countries, less nitrous oxides and methane is emitted while at the same time it would also yield a more balanced distribution of the calorie intake from meat and dairy across more world regions with benefits for food security.

“The models agree that diet change can contribute only part of the efforts needed to achieve the 1.5°C climate stabilization target and policymakers should not forget about the production side measures which in this study provide the large majority of the mitigation potential.” says IIASA researcher and coauthor Petr Havlík. “The comparison across multiple models also shows that there are still substantial uncertainties in the reference level non-CO2 emissions development and the related mitigation potential. Unless these uncertainties are reduced, they will need to be factored in the plans of deployment of negative emissions technologies”.

As countries will have to periodically monitor progress and take stock of the implementation of the Paris Agreement, the insights provided in the study could help policymakers to identify regional mitigation priorities in the sector and have a better understanding of the potential contribution of agriculture.

Think the human race has hit Peak Stupid, you ain’t seen NOTHIN’ yet! Anyone who thinks eating nasty, watery vegetables and sugar-bomb fruits is “good” for you needs to read, cover-to-cover, the seminal work of Dr. Weston A. Price, “Nutrition and Physical Degeneration.” Take a GOOD look at the before and after pix of tribesmen the world over who switched from their traditional diets, high in animal products and devoid of refined grains and sugars, and the trainwreck their health became.
Especially their kids. Horrendous!

People talk about lowering sperm counts, the sudden fashion for sexual confusion, and birth rates below replacement. These things all can be 100% correlated with decreased consumption of the core building blocks of the human brain and body–red meat and butter from pastured cattle, wild caught oily fish, and their replacement with SAD-CRAP: “Standard American Diet, Carbohydrates Refined And Processed.” The vegans will just plain take themselves out of the gene pool.

Many anthropologists think it was a meat heavy diet after the invention of fire that caused mankind’s brain to rapidly expand over a relatively few number of generations. The desire to restrict meat is part of the effort by elites to dumb down the people and make them more compliant for being manipulated. If these idiots had their way, meat would get so expensive that only the elites will be able to eat meat.

Yes, apparently they want to ‘stabilize’ seasonal variability and equalize the climate from the poles to the equator.

It’s beyond comprehension that these idiots consider the ‘natural’ state of the climate system to be static. If the climate wasn’t always changing, it would be broken.

The only time the climate will ever be static is long after the Sun dies, leaving a cinder of Earth behind cooled to a constant few degrees K.

I have yet to see an analysis of the climate sensitivity of Methane and/or nitrous oxide such as that done by Moncton of Brenchly for the court filing in California re CO2. His filing showed the science was WRONG regarding the feedback calculations. I suspect the same error may have occurred regarding methane and nitrous oxide. It may be possible that no amount of reduction of those molecules would have any real affect on the global temperature for thousands of years.

The climate sensitivity has one and only one value which is independent of the origin of the W/m^2 of forcing. The IPCC and its cohorts try to obfuscate this by claiming the sensitivity is 3C for doubling CO2. There are so many levels of indirection and misdirection between a testable sensitivity metric quantified as W/m^2 of surface emissions per W/m^2 of forcing and an unverifable sensitivity metric of 3C from doubling CO2 that it leads alarmists and many skeptics down a rat hole of illogical reasoning, mostly involving impossibly large amounts of ‘feedback’. But then again, this is the point of all the obfuscation.

The ONLY sensitivity metric that matters is 1.62 W/m^2 of surface emissions per W/m^2 of forcing and that each W/m^2 of forcing has the same effect on the surface. Any other metric is unmitigated BS, unquantifiable with theory, unmeasurable from the data, contradicted by the laws of physics and its only purpose is to provide a false justification for the repressive agenda of the UNFCCC.

The actual sensitivity is the Planck sensitivity metric corresponding to a gray body with an emissivity of 0.62. The fundamental error made is that feedback can somehow amplify the Planck sensitivity by a factor of 3-4, which the laws of physics tell us can only occur by changing the effective emissivity (0.62 for the Earth) and not by modifying the 4 in the T^4 relationship between degrees and W/m^2 which is otherwise required to support the IPCC’s bogus sensitivity. To increase the Planck sensitivity by a factor of 3 requires reducing the effective emissivity from 0.62 down to about 0.23 which would require the surface emissions to be 1039 W/m^2 corresponding to a surface temperature of 368K, which is close to the boiling point of water and an obvious falsification of the claimed sensitivity.

With having a half life of only 7 years, methane from farm life could be quickly reduced if global temperatures started to rise rapidly (which isn’t happening).

” … a more balanced distribution … meat & dairy across more world regions …” the authors actually say. I guess the danger from animal husbandry is not absolute, but relative to who the authors deem suitable beneficiaries of CO2 equivalent emissions.

And, as someone asked in a prior WUWT post comment thread, what is the shared sacrifice that rice consumers should make to reduce methane emissions associated with rice production? Maybe the authors should get on the old cocconut wireless & learn the vaunted Paris Agreement is already a non-performing relic.

There are plenty of people in fly-over-country whose primary source of protein is what they hunt.

Agriculture just makes obtaining a reliable source of protein more efficient while profiting those who provide the service.

Instead of cattle, poultry and swine, there will be a growing market for “wild” game (wild both in nature of the animal and the lack of inspection and processing standards) and the quality of life takes another step backwards.

WR: Totally wrong: the oceans are the largest source of non-CO2 greenhouse gases emissions: water vapor H2O. The number of H2O molecules in the atmosphere is around 25 times the number of CO2 molecules. As water stays around 10 days in the air ( every day (!) two and a half times the total number of atmospheric CO2 molecules is emitted by oceans and plants/trees. Too significant a number to overlook.

Except that these flows are in the current account of the carbon cycle and not a perturbation of the carbon cycle by external carbon that was previously sequesteted under the ground and then dug up by humans (the AGW issue). Also the attribution of increases in atmospheric methane to human activity overlooks natural flows. Please see

The study is bogus because they forgot to include consideration of the primary greenhouse gas, H2O. Considering that H2O accounts for most of the radiant greenhouse effect I doubt that changing our diet will have any significant effect on the overall radiant greenhouse effect if there actually is such a thing.

Reply to  Wiliam Haas
December 19, 2018 9:04 am

The radiant GHG effect is the only effect they have and when combined with a similar effect from the liquid and solid water in clouds results in increasing surface emissions beyond the forcing by 600 mw per Watt of forcing. The foundational error made by the IPCC is applying nebulous positive feedback to amplify the 600 mw up to 3.3 Watts of additional surface emissions per Watt of forcing.

This error is so obvious, but also so large, that many on both sides have a hard time accepting that an error this big is even possible as the result from ostensibly intelligent scientists. They don’t account for the fact that political bias, much like a lack or protein in the diet, makes people stupid, and this also applies to those ostensibly intelligent scientists.

Does the model determine how much new farmland is needed to grow the protein-containing crops that will be needed if meat is no longer produced? Is that much land available? Does it include the emissions from this added farming? Does it include the added greenhouse gas emissions from management of farm waste that is no longer consumed by farm animals?

Not any more.
Science is going backwards, millions of deaths per annum.
Deaths from ‘diseases’ and causes that were unknown barely 80 years ago.
40% (at least) of everyone who passes away today, tomorrow etc etc will have died through one of those ‘Modern Day Diseases’

Yet it was known, two hundred years ago that a diet high in animal fat was the key to being tall, svelte & elegant, alert & intelligent, good humoured & empathic plus- relative immunity to common ailments.
Generally, a diet including animal fat was the key to good physical and mental health.

Take a walk through a shopping mall, a busy supermarket, glance at ‘science’, ‘education’ and ‘politics’.
Do you see people displaying (m)any more than even just one of the above characteristics.?

And even the Lead Picture into this article is ‘less than correct’ – I don’t see a lot of fat on that lump of meat.
And what does the wine represent if not a symbol of ‘animal blood’
The drinking of same being held in a small, intimate and deeply reverential ceremony that hunters would hold after catching/killing their prey to give thanks to ‘raise a toast’ and say Thank You to the animal they’d just caught.
Thank you for giving *your* life that we may have ours.

And alcohol drinking now?
One Big Phat Joke, a Flat Out Lie about ‘being social’ and an opportunity to get even more dumb & stupid than the lack of fat in our diet brings on.
Even before (how) many of us were inflicted with Kwashkior in the first 3 years of our lives through being bottle-fed babies.

How do you, how does anyone, even start to turn that one around?

How many will die before that science progresses?
It has to progress, because Climate Science is a direct consequence of our current low standard of nutrition.
Simply, the lack of fat.

December 19, 2018 3:02 am

70% of the earth’s land surface is classified as “rangeland”. It is only suitable for grazing.

Remove livestock from it and vegetation will still grow, and it will be eaten by methane-article g animals, methane-farting termites, or smoke and co2-producing fires.

This doesn’t include the montane, forested and wetland areas that are also unfit for crop-farming. They certainly aren’t thinking too hard about what happens to those remaining acres that are supposed to grow all of our food.

Then there is the question of what we do with the products of cropping that are not fit for human consumption and which are currently fed to livestock.
