A commonly quoted defense of our livestock systems is/was an outcome from the Paris Climate Talks Agreement (2015) I.e. that GHG emission reductions should not come at the expense of food production as per Article 2. This can easily be argued as a correct interpretation as the two below segments extracted from the UNFCCC site state:
Recognizing the fundamental priority of safeguarding food security and ending hunger, and the particular vulnerabilities of food production systems to the adverse impacts of climate change, (p1)
(b) Increasing the ability to adapt to the adverse impacts of climate change and foster climate resilience and low greenhouse gas emissions development, in a manner that does not threaten food production; and ... (p3)
The document these quotes comes from, at 27 pages, appears to be a relatively summarised summary but a useful go-to resource.
Despite this, livestock agriculture in New Zealand in particular has received a lot of negative publicity and pressure to down-size. Much of this comes from groups who are committed to seeing animals removed from the food cycle for reasons other than climate change, but climate change fits their argument, so it is an opportunity not to be missed.
Perhaps, not surprisingly, given the amount of documentation that comes out of the UNFCCC and associated bodies it could be argued that all attitudes and arguments can find some sort of supporting statement, a little like groups can find supporting statements in the Old and/or New Testaments to support positions.
So, when a more detailed search is done the later published (Climate Change and Land. An IPCC Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems[2019] ) and far more comprehensive document is read (all 906 pages) then a different view may be extracted.
The difference between the two documents is that it was the Paris Climate Talks Agreement that the New Zealand government signed up to, not the latter. However, this shouldn’t be used as a reason to not recognise that within the latter there is plenty of relevant points raised that may and probably are influencing at least some (and likely our government's) actions and responses.
One poignant point that they raise is the ‘law of unintended consequences’ which can result from perverse outcomes when things done for one reason, often a ‘right’ reason, can end up with not achieving the result desired. New Zealand agriculture has a long and continuing history of trying to achieve better production and efficiency. This is largely to gain better economic returns by lowering inputs for a given output. DairyNZ in particular highlights the fact that New Zealand has one of if not the lowest cost of emissions for a given product output and Beef and LambNZ are not far behind in this view. At face value this is a credible result to be aimed for, however as the IPCC document points out;
Increases in economies of scale linked to increased efficiencies and decreased emission intensities may lead to more emissions, rather than less, an observed dynamic referred to by economists as a ‘rebound effect’. This is because increased efficiency allows production processes to be performed using fewer resources and often at lower cost. This in turn influences consumer behaviour and product use, increasing demand and leading to increased production. In this way, the expected gains from new technologies that increase the efficiency of resource use may be reduced (for example, increase in the total production of livestock despite increased efficiency of production due to increased demand for meat sold at lower prices). Thus, in order for the livestock sector to provide a contribution to GHG mitigation, reduction in emissions intensities need to be accompanied by appropriate governance and incentive mechanisms to avoid rebound effects, such as limits on total production.
One of the comments posted on Keith Woodford’s article alluded to this earlier this week , stating; “It all seems such a ridiculously futile exercise to me, when the solution to both water and atmospheric pollution is to apply a carrying capacity approach by limiting un-natural inputs to land. Farm/produce within the limits that the ecosystem of your property allows.” For most farmers the direct limitation approach would go down like the proverbial lead balloon, however, many analysts already are agreeing that the high price of dairy products is largely due to the fall in supply coming out of the northern hemisphere, so a win, win is potentially possible.
In addition, the argument that New Zealand farmers are providing the world a service in supplying the world in valuable food supplies is a disingenuous argument. If that was our driving motivation we would be farming much of our flat/suitable land in arable crops. More food per hectare and at lower inputs of costs and water (on irrigable land) and less of an environmental toll. There is still a place for livestock production but let us not defend it with using a supposed moral high ground, when it is profitability driving it.
Let’s face it, we all are in agriculture to primarily make a living, in a lifestyle we enjoy, working with the systems we enjoy most (some of my best friends are sheep). But it needs to be clarified that:
Article 2 of the Agreement makes clear the agreement is within ‘the context of sustainable development’ and states actions should be ‘in a manner that does not threaten food production’ to ensure food security.
It doesn’t state that things shouldn’t change. The Agreement was also made within the context that global warming would be kept under the +1.5% increase in temperature. It is now looking increasingly likely that this is going to be exceeded. Does this change our expectations of what should be done?
On a converse argument, the report mentions;
Price increases in turn lead to reduced consumption, especially by vulnerable groups, or to shifts towards cheaper food, which are often less nutritious. This leads to significant increases in the number of malnourished people.
On the positive side the report while strongly denounces deforestation, it does not advocate converting productive food producing land in forestry. For interests’ sake a ‘model’ of the report authors’ thinking is shown below. It does not show anything that has not been discussed at some point, but show points of intervention that may help in GHG emissions.

The purpose of this article is not the decry our livestock system and try to replace them with arable or other ‘higher producing’ systems but to highlight the issue of putting up the argument of “safeguarding food security” by itself as a reason for continuing what we do will increasingly come under pressure and using the argument of “there are no workable solutions” may not cut it in the future.
Or market forces for higher producing land uses may create change by itself.

Excellent article Guy , I have often seen the point raised "not at the expense of food production " as you pointed out this is used as a defence of existing production without taking into account alternative foods that could be produced on the land . Another point is in the production of the likes of dairy externalities are not costed in eg pollution. If these were priced in the metrics of the profit would be quite different.
A key question is what should those alternatives be?
The staple crops we can grow are wheat, barley and oats. However, the costs are high linked to the resources needed to grow those crops in a maritime environment that is very different to the continental climates where those crops evolved. To think of these crops as an ecological solution is greatly flawed.
Rice and soy are not possible because of climate.
Corn is feasible in some parts of NZ but definitely not economic on world markets - it is only an option for local consumption.
Very little of NZ's pastoral land is suitable for arable crops owing to the combination of topography, maritime climate and low fertility.

Indeed. I made a similar 'Paris Agreement does not mandate status quo food production' comment on Keith's article. Meat production and consumption are simply too high for our natural environment and our health. We did not 'evolve' to eat 126kg of meat per head per year.
The 27 page Paris Agreement is not a summarised document. It is the full document that was signed up to under the UNFCCC.
In contrast, the IPCC documents over the last 30 years add up to many thousands of pages. The purpose of the IPCC is to present and discuss the science - what is known and what is not known. But it is not a policy organisation. And in presenting the science, with all of its uncertainties, it is not tasked with evaluating the trade-offs between objectives.

DairyNZ in particular highlights the fact that New Zealand has one of if not the lowest cost of emissions for a given product output and Beef and LambNZ are not far behind in this view.
I think that's a point that often gets lost when we only look at the local situation rather than the global one. If we stopped dairy and meat production here to "save OUR environment" (and they do have very real and significant impacts locally) the global consequences would be that those products would simply be produced somewhere else with even worse environmental outcomes (local and global).
The law of unintended consequences is a real killer. The road to hell is paved... etc
Worldwide, there is a significant movement towards eating less meat, possibly less so for dairy. Similar movements following food miles, which has morphed into carbon footprint. A better overall picture. Both represent opportunity and challenge for nz. Do we continue to pump out wmp and mutton flaps for auction to highest bidder, or do we concentrate on lower amount of high value, hopefully value added products. The Chinese export virtually no raw product, in some cases exporting components is controlled, if they think value can be added in China. But that product needs to be clean green,and animal friendly. Just look at free range eggs.the market premium is there for a product conceived to be carbon neutral, etc, but it need s to be certified, and above scrutiny.
The problem is that those premiums are rather modest, and essentially zero in the ingredients business. The key premiums relate to food safety and we already get those. When it comes to green premiums, what people say they will pay and what they actually pay ('revealed preferences") are very different.

Intially it might be 5 or 10% per year, but it would grow. The opposite is also possible, nz becomes the bad boy , pointing out our emissions per capita , and pictures of cow in mud. Yes, I know it's not true or fair, but little in politics or business is. Especially when your the small player.
Look at the criticism China gets, (even on here, where you'd think most posters are well informed), for its coal use, despite it doing most of the world's dirty manufacturing, and it's domestic carbon use per capita been very low.of course it must improve, or shift that manufacturing to Brazil, or similar trump like arrogant country.

That's kinda my point. If we're the most efficient at producing WMP and mutton then that is what we should be doing. As long as there is demand (which is certainly falling, and that is probably a good thing for our health and the environment) then globally speaking we should be encouraging the most efficient systems to pump out more than the inefficient ones. A bit like, as Keith pointed out to me yesterday, our wheat growing is not very efficient, so we should be getting it from somewhere else. Of course current geopolitics have made global trade a bit more complicated.
Food miles was a bit of a red herring IMO, as transport is often just a tiny proportion of energy/water/CO2 usage/production. NZ lamb makes more sense in the UK than Welsh because of the different growing systems. Sounds mad, but that doesn't make it untrue...
Overall global demand for dairy is increasing. It is milk, rather than total dairy that is decreasing, with this more than compensated by other dairy products such as cheese and to a lesser extent yoghurt. As for global meat demand, that too is increasing. Unfortunately, those people who rely on mainstream media would not know either of those facts.

ha! I did exactly what I was talking about earlier, thinking local (nz meat consumption has come down abit, red meat in particular ) and forgetting about the global
https://ourworldindata.org/grapher/daily-meat-consumption-per-person?tab=chart&country=NZL~OWID_WRL
I'm thinking less about overall meat consumption, more about growing the high end of the market , which may require change s that limit production. I know it is trotted out at every election, usually with no detail about how to do it. I believe silver fern farms is attempting to market this advantage.
I also think it is a much bigger factor overseas than here. I remember working in London in the late 80's, boycotting food from South Africa was a huge movement, whereas the only thought here was rugby. Though England probably imported a lot more food from S.A than we did.
Oh dear. This is all predicated on enteric methane being the major source of biogenic methane. This is akin to saying all smarties are green. Why? Because we only count the green ones. All living systems produce methane as the bugs responsibles exist in every environment. Here in NZ we have no idea what % of biogenic methane is attributable to livestock because we have never measured the total. Livestock as a compact unit can be placed in a chamber and measured, but how do you compile a figure for the temperate rainforest of the WEst Coast? Bear in mind that the largest source of biogenic methane is the Amazon rainforest (It's still quite big admittedly). The point is that changing land use will not give as large a methane dividend as people might think.
Atmospheric levels of methane are measuired by satellite, which can also distinguish between biogenic, fossil fuel leakages and burning sources. Simply stopping pipeline gas leaks and fracking escapes will more than bring global methane back to a net zero balance.
Also never mentioned is that the hydroxyl ions responsible for methane oxidation come from transpiration from green plants. Yonks ago scientists showed how these hydroxyl ions from grassland could oxidise 10 times the enteric methane from graziers.
Feedlots are a different story.

I think you might be conflating hydroxyl radicals with hyroxide ions.
Hydroxyl radicals are what oxidises methane, but these radicals have a lifetime in the atmosphere of less than one second.
This links to why methane is assessed to have an atmospheric residency of about 12 years - there are not enough hydroxyl radicals to do it any faster.
KeithW
I accept hydroxyl radicle in place of hydroxide ion. However there must be a somewhat more resilient oxidation process to prevent methane levels from for ever increasing, given the numerous sources. The 12 years average is also confusing as surely there is a constant atmospheric pool which is continuously in a state of flux. It's this pool we do not want to see increased. I wish I could lay my hands on the recent estimates regarding the state of methane flux, but from memory the imbalance (additional methane) is less than fugitive emissions from the gas industry.
Here is a graph from NOAA
Currently increasing exponentially.
The explanation could well be that the oxidation potential from hydroxyl radicals has maxed out.
Have a read of this paper.
