COP29 NOV 11--Blue Zone

review of the notes from my first day of the UN COP29 Climate Change Conference. Disclaimer I'm just a ~silly guy~ not a policy or geopolitical expert. My observations and opinions do not reflect AC or RINGOs. This is what I witnessed, overheard, remember, and (crucially) understand, and may not be representative of final policy decisions.

I was in the Blue Zone today (official UN ground, where negotiations occur). From the RINGO meeting, rumor was the night before COP29 officially began officials were up till 4 am arguing about the agenda. Article 6.4 of the Paris Agreement (mechanisms of carbon markets) was deeply contested in particular. Also arguments about unilateral and multilateral trade agreements. Also weather Global Stocktake (assessment of global progress on Paris Agreement) would be filed under general or financial sections. US/EU/Australia/smaller island nations were wanting it to be considered broader, with BASIC (Brazil, South Africa, India and China) wanting it under strictly Finance. More Paris Agreement stuff.

This resulted in the opening plenary beginning at 11 am, followed immediately by break for closed door discussions on the second item of the day, the agenda. This was a completely unprecedented delay, and the agenda was only resolved at 9pm.

This is the previous COP president Sultan Al Jaber, who did the opening address of plenary and handed over the presidency to Muhktar Babayev (photo below) with an embrace.

Notes of claims from Babayev's address to the plenary body:

We are set to break records on renewable energy and its investment.

There is a goal of low-carbon growth (as opposed to zero, which I think is an important distinction)

853 million put into the Loss and Damage fund

A call to increase climate financing ambitions. This is not charity, but in the self interest of all countries who with to mitigate the ethical and economical consequences of climate change.

A reinforcement of the call to transition away from fossil fuels (important, as last year is the first time such phrasing was used for the UNFCCC)

Emphasizing the cooperation required of everyone.

Genocide and the environment

Social justice is deeply tied into climate change efforts. Here in the Blue Zone we had a demonstration to end genocide (as relevant by its massive carbon emissions, if the human rights angle doesn't suffice), with particular emphasis on Palestine and reclaiming Indigenous lands. Demonstrations within the blue zone are allowed with permission, and can have a maximum of 20 people actively participating. Those in solidarity of the demonstration raised their fists in support. Also, this could not happen in the Green Zone (public conference) due to it being controlled by the host country, and Azerbaijan has strict laws against protests.

USAmerican election and its future climate policy

I proceeded to get rather lost trying to find a conference on USAmerican climate response to the Trump election, but got there too late because the Blue Zone is massive oof. Did catch the people coming out, and the strategy thus far is that the Biden administration's environmental policies were designed to endure regime shifts and should be difficult to undo without significant political effort. So, we'll be unfortunately testing that durability, particularly with how Trump likes to flout the rules and the Supreme Court deemed that legal.

Additionally, NDCs (Nationally Determined Contributions) are due in February but the US may potentially do theirs sooner before the regime shift. Effectiveness is questionable because the accountability of countries upholding their NDCs is already kinda honor code.

Subfederal action is going to be a main proponent of climate action from here on.

Conference: Transparency for transforming the agrifood system

I...must admit I was constantly blacking out and jerking back awake during this meeting because of jet lag. So the merit of these notes may be questionable particularly bc I'm having trouble reading them. However, notes from representatives from Mongolia, Pakistan, Georgia, UN, and others.

10% of global green house gas emissions are from agriculture (Technically this was from Babayev's speech but I think it's a useful reference point for this conversation. Production, manufacturing, distribution, and waste of food produces a lot of emissions).

Data quality is of large concern for transparency and effectiveness of implementation purposes. Countries have different methodologies and argue about which is superior, and the quality of others' methods. This can be particularly of note in the carbon markets. Data collection is a large logistical and technological challenge.

Everyone wants increased transparency. Or claim to. I think, aside from technical difficulties in data collection and funding thereof, the countries would actually prefer others are transparent and less themselves to be. As evidenced by things like high levels of methane unaccounted by the summation of all countries' submitted emission reports. But that's just my opinion.

BTRs (Biennial transparency reports) are difficult, and the country representatives present were apologizing for delays.

Calls for increase of human capacity. Imma be level that seems like a vague ideal to me, but I think it might mean carrying capacity (kinda a deeply flawed concept already, sustainability is extremely difficult to ascertain without prolonged unsustainability to confirm it)

Double counting is a problem for carbon removals

Efforts to work with farmers in data collection and to better improve their methods

A claim on carbon neutral livestock farming to balance cattle methane emissions with soil carbon sequestering through grazingland ecosystem management.

Conversion of carbon sink ecosystems into farmland. From personal research: In 2019, 17% of global cropland was newly converted since 2003, and the rate of yearly conversion is accelerating.

Potentially using IPCC software for consistency in data collection and analysis

Ecocide as a tool of war

Lastly, there are country pavilions in the Blue Zone where they raise issues. I did not particularly look too much into most of them, but would like to share Ukraine's because it was amazing imo.

One, the walls are literally full of seeds, and I think it will be really cool seeing them begin to sprout by the end of the conference

Two, how destroying the environment is a concentrated effort to destroy its people. Because again, protecting the environment/climate is protecting the people.

Lastly, these solar panels damaged in the war. A large emphasis in this pavilion was rebuilding from the bombing and coming back greener, which I found particularly admirable. The bravery to forge something new while grieving the comfort of what was lost. The circumstances presenting the opportunity to reinvent their infrastructure is obviously horrendous, but seizing said opportunity nonetheless is inspiring. Renewable energy is also a way to be energy independent, which is particularly important if you’re say Ukraine and the closest major oil exporter is Russia.

Now, I had left the Blue Zone by then (needed dinner where there isn't price gouging! Yikes!) but plenary did eventually assume very late, and massive progress on Article 6 was made!

This is about Carbon Markets, some people are happy others aren't, etc. Also the agenda was implement as the original plan (GST under finance) with acknowledgements made that it was broader consideration. And now plenary can actually continue instead of being stymied! In consideration for the day of lost time, sessions will run later than usual. After today it's going to get busy!

Having a thought about how the amount of wealth Bruce comes into and then amasses for himself changed over the decades of Batman media, and the reason he's beeen scaled up to be so impossibly wealthy is probably because cities and companies in DC lore are analogs to real life places and companies.

Wayne Enterprises probably reflects how homogenous American multinational corporations are now, where a single company can make and distribute almost all consumer goods because it has bought out/merged hundreds of smaller companies + purchased everything it needed from the ground up so it does not depend on many others besides itself.

Just something that crossed my mind when I was looking up what WE actually does and the Fandom (bleh) wiki listed so many branches. Wayne Shipping? Wayne Foods? Like...is this Amazon and Bruce is now Bezos? Wayne Entertainment? He's also Disney? Wayne Electronics? This is Apple? Wayne Aerospace? Boeing??? Bruce is trying to be in control of and monitor every single means of production and every production line fr

Feel like that should influence how people view Wayne Enterprises and Bruce himself. Steadily creeping in and taking root in every industry. People get curious about a new construction project in the city, but once it's revealed to be a Wayne Tower it's filling people with dread. Though, it was a long time coming...everything you order online comes in a box with a W on the tape delivered to your address in a black as night truck with a giant W emblazoned on the side. The meds in your cabinet were produced under Wayne Pharmaceuticals. The cable and streaming services were recently bought by Wayne Entertainment. The Wayne Foundation started offering scholarships at the major college campuses. Your phone is Wayne tech. Your car was built with Wayne Steel. Soon the hospitals will be all Wayne Medical, your insurance company bought out. The local newspapers and stations will be bought up. The libraries. The clinics. The orphanages. The schools. The grocery store. You're never going to scrub that b ig soulless W out of your head. The way the logo looks like the head of a pitchfork, ready to stab and capture the intended prey.

Thinking about how Wayne Medical seems so innocuous in what it does except for the bit on how Bruce has access to every person in Gotham's medical records, because he can access the Wayne Medical databases and use that information to track suspects. And the thing is WE does not just exist in Gotham, it's a multinational corporation with bases in major cities not just in the U.S. but around the world. This man has millions of people's medical records easily accessible to him which feels both extremely unethical and extremely illegal. Not that civilians can prove he can and does access those records though.

The Impacts of Agricultural Practices on Arbuscular Mycorrhizal Fungi

By popular demand (one single person) I present a semster's worth of research into the scientific uncertainty surrounding Arbuscular mycorrhizal fungi as pertaining to agriculture because oh boy. is there some uncertainty. Which is a boring way of saying the world is ripe with potential and the mycology is a blossoming field of research! Yippee!

Arbuscular mycorrhizal fungi (AMF) have potential to increase the efficiency of modern agricultural practices due to its beneficial impacts on crops. AMF are a broad category of fungi species that live in the soil and connect to the roots of plants, forming symbiotic relationships between them and other plants connected through the mycelium network. Due to their fine mycelium and ability to extract nutrients from inorganic compounds, AMF can access nitrogen and phosphorus from the soil and exchange it with for carbon compounds generated in photosynthesis by their plant hosts (Hodge and Storer 2014). This can provide crucial, often limiting nutrients to crops which otherwise deplete the nutrients in the soil with each harvest. AMF have also been found to increase plant resistance to pathogens, drought, or salinity (Cheng et al. 2023; Buysens, de Boulois, and Declerck 2014). However, the benefits of AMF to crops vary wildly, and in the wrong conditions AMF can become parasitic to their hosts (Hodge and Storer 2014). The complexity of AMF networks makes it difficult to ascertain their impacts, with variables such as available nutrients, soil conditions, or species involved in the symbiosis changing the results of studies. One component of addressing its potential use comes from examining how current farming practices impact the effectiveness of AMF for agriculture and the uncertainty obfuscating it.

Nutrients

Modern agriculture depends on ample fertilizer use to maintain yield output, which has heavy environmental costs, from excess nutrients causing eutrophication, to being carcinogenic and potentially radioactive, to the damage from mining and processing phosphate (Lubkowski 2016). One of the main advantages of AMF symbiosis is increased access to nutrients for the crop hosts, thus positioning it as a potential alternate source of nutrients. Understanding both the impact of fertilizers on AMF networks and how they compare in enriching crops is crucial when considering the potential of AMF in agriculture.

Over time, conventional fertilizers' usage greatly decreased the diversity of AMF species and their impact on crops (Oehl et al. 2004; Wang et al. 2018; Peng et al. 2023). Organic fertilizers resulted in nearly double the amount of AMF species compared to the plots using artificial fertilizers (Oehl et al. 2004). The composition of the fungal species was also different, with the species prevalent under organic farming more closely resembling those of a natural ecosystem. Furthermore, the dominant AMF species under long term, high intensity artificial fertilizer were less beneficial to crops (Peng et al. 2023). Potentially less efficient AMF species were selected for by high input farming as the crop would trade for phosphorous less readily due to the abundance from the fertilizer (Oehl et al. 2004). Less diversity in AMF resulted in decreased benefits to crops, suggesting that farming techniques that increase the diversity of AMF will be more beneficial to farmers (Oehl et al. 2004; Wang et al. 2018). However, Peng et al. found that the lower AMF diversity in fertilized fields did not cause lower crop yield, but did find increased soil stability and nutrient cycling (2023). As it was the diversity of the AMF being measured, the diverse and partially conflicting results are logical because of the different AMF species and dynamics present in each study. AMF diversity appeared to relate to multiple but inconsistent positive effects for agriculture and was clearly harmed by the use of conventional fertilizers.

Fertilizer negatively impacted the root colonization of AMF (Oehl et al. 2004; Sheng et al. 2012; Peng et al. 2023). Cultures taken from organic farming plots had a higher chance of inoculation and faster root colonization compared to traditional fertilizer use (Oehl et al. 2004). AMF species that quickly and more fully colonize roots would be highly valuable in modern agriculture, which prioritizes annual plants and thus would need to quickly renew relationships with AMF networks in order to benefit from the symbiosis. Potentially the particular species predominate under organic farming was well suited to swift colonization of the crops used. Alternatively, the diversity of the AMF species may have been the cause due to an increased chance of having a fungal species suited to the crop species. More testing is necessary to ascertain which variable has the greatest impact on root colonization.

Other indicators of fertilizer impact on AMF growth were not so clear-cut, as hyphal and spore density had conflicting responses to long-term fertilizer use. Sheng et al. posited that the limited benefits of AMF in fertilized fields could be attributed to added phosphorus causing limited hyphal growth in the top layers of soil, reducing the amount of root connections with crops (2012). However, Peng et al. found that hyphal length density increased with the addition of nitrogen and phosphorus in tandem but having neutral impact separately (2023). Potentially the negative impact Sheng et al. noted was influenced by a lack of nitrogen, but that would not fully explain the anathema results. Additionally, in two experiments fertilizer increased the spore density, potentially due to the fungi being in unfavorable conditions and consequently switching from an emphasis on hyphal growth to spores to increase their long-term survival (Sheng et al. 2012; Peng et al. 2023). In contrast, Oehl et al. found a decreased abundance of spores in fertilized fields (2004). The reason for the stark contrast in results is unclear, and could be contributed to different crop species, duration of studies, soil characteristics, or any other plethora of variables that without further study will not be elucidated.

Soil Organic Matter (OM) also influenced the relationship between AMF, fertilizer, and harvest due to influencing the amount of nutrients available to plants. The benefit of fertilizer on inoculated raspberries was significantly less pronounced in high OM environments, where the weight of berries had a negative relation to the amount of fertilizer (Chen et al. 2022). In low nutrient conditions with low OM and fertilizer usage, inoculated raspberries had small berries, potentially due to the host and fungi competing for limited nutrients. A similar trend was found with the fruit set, or percentage of flowers that produced berries. In an inoculated field with low OM, fertilizer increased the fruit set but in high OM it decreased (Chen et al. 2022). Furthermore, the highest fruit set belonged to an inoculated field with high OM and no fertilizer. Therefore, there is likely a limited range of available nutrients (whether from OM or fertilizers) wherein AMF are beneficial to crops, suggesting that future experiments concerning AMF and fertilizer must take pre-existing soil nutrients into consideration. Further testing is required to determine the optimal combination of OM and fertilizers to achieve the benefits of AMF, because as of yet the impact of nutrients on AMF networks is still not fully understood.

Crops

The AMF represent only one half of the symbiotic relationship, and so the hosts available to them greatly determine the impact of AMF. The harmful effects of annual monocultures are well established, resulting in decreased biodiversity and nutrient loss that could negatively impact AMF networks (Crews, Carton, and Olsson 2018). The prevalence of monocultures in modern agriculture raises the question of how the limited selection of hosts impacts AMF networks.

Crop diversity is clearly linked to AMF diversity. Oehl et al. suggested that the seven- year crop rotation method used in their experiment contributed to the high diversity of species, as they had more similar numbers of species in wild grasslands than is found in cropland that utilizes the same monoculture every year (2004). Intercropping systems were likewise found to sustain richer and more diverse AMF communities than monocultures (Lu 2018; Cheng et al. 2023). It is likely that the variety of the hosts provides a variety of symbiosis opportunities for differently adapted AMF species to bond with, thus increasing the AMF diversity and richness.

But as previously discussed, AMF diversity is not a clear indicator of benefit. Crop diversity may benefit AMF networks, but farmers are more interested in how that impacts crops. Intercropping results in a significant increase in yield compared to monocultures, known as over yielding. Cheng et al. found a positive correlation between intercrop yield and AMF diversity, though Wang et al. clarified that not all inoculated crop species in an intercrop system experienced an increased yield, further cementing how varied AMF-crop interactions are (2023; 2018). Lu hypothesized that the AMF nutrient transfers explained over yielding in intercropping system but due to confounding variables it was difficult to ascertain (2018). Notably, the yield benefits of intercropping were diminished in fields with high amounts of phosphorus from added fertilizer (Wang et al. 2018). Combined with the theory that less beneficial AMF were selected for in fertilized fields, the success of intercropping beneath conditions favorable to AMF suggests AMF could be a contributing factor to the over yielding phenomena found in intercropping and thus practice that support AMF are vital to intercrop systems (Oehl et al. 2004; Peng et al. 2023).

Annual crops dominate modern agriculture and thus their relationships with AMF are valuable to examine. The disruption of the soil from the tillage necessary for annual crops results in severe soil and nutrient erosion in a way that is unsustainable (Crews, Carton, and Olsson 2018). Tillage has a harmful impact on AMF due to severing the mycelium networks, so the practices associated with annual crops are already known to harm AMF communities due to severing mycelial networks and causing changes in nutrients (Peng et al. 2023; Sheng et al. 2012). Periods of bare soil between yearly annuals and destruction of weeds result in stretches of time when AMF have reduced host possibilities. Overall, the associated farming techniques used for annuals are not beneficial to AMF.

Annual crops also face the added complication of new plants having to re-establish their symbiosis with AMF. Due to the lag in benefit from AMF, short-lived plants may be less likely to invest in a symbiotic relationship with them. Perennial legumes with AMF networks had more growth than annual species, with increased nitrogen and phosphorous given to the crops (Primieri et al. 2021). It was possible the AMF reinvested in perennials over and over because they have proven to be good symbionts, whereas there was a time lag in reinvesting in a new year of annuals. Therefor agriculturalists using perennials may have even more investment in using practices that compliment AMF as they have an increased impact. However, the study’s results should be treated with caution as the perennial crop was an undomesticated crop species due to farming crops being mostly annuals and comparisons show that domesticated species can be less able to support AMF (Primieri et al. 2021). Because species react differently to AMF symbiosis, studies between annual and perennials were difficult to construct. However, combined with the associated practices of tilling and periods with decreased access to hosts, it is likely that AMF is more helpful to farmers in perennial systems. Though there is some uncertainty, the consensus of research is that perennial and diverse crops have more beneficial symbiotic relationships with AMF.

Pesticides, Herbicides, and Fungicides oh my!

Conventional farming heavily relies on utilization of hazardous chemicals to kill organisms that pose threats to crops, be they rivalrous weeds, hungry herbivores, or fungi plagues. While pesticides seek to target specific species or groups, the introduction of toxins in the environment often has unintended side effects that could be influencing mycorrhizal networks. Studies conflict greatly whether pesticides help or hinder AMF, in part thanks to the plethora of confounding variables involved.

The species involved in the system are a large factor in the effect pesticides have on AMF. Different AMF species have various methods of dealing with toxins in their environment, such as compartmentalization, producing protective molecules, and transporting pollutants (Hage-Ahmed, Rosner, and Steinkellner 2018). Therefore, the response an AMF network has to pesticides will depend on the predominant fungal strains. As AMF are in symbiosis with plants, their species are also relevant. The application of herbicides to weeds limits the number of hosts the AMF are able to rely on. However, in some studies the AMF were able to recover after a few weeks, though their ability to do so was dependent on the crop species they were partnered with (Hage-Ahmed, Rosner, and Steinkellner 2018). Other studies even found herbicides had a neutral or positive impact on AMF. Soil bacteria that associate with AMF can also vary in quantity and quality within the same field, especially species that biodegrade pesticides and influence their persistence (Hage-Ahmed, Rosner, and Steinkellner 2018). Due to AMF being symbiotic networks, the species at play, be they fungal, plant, or bacteria, can all highly influence how the system responds to pesticide disturbances.

Fungicides potentially pose a threat to AMF due to being designed to target fungi. At IC50 threshold to control a fungal pest, three fungicides had no impact on AMF except for flutolanil decreasing root colonization (Buysens, de Boulois, and Declerck 2014). Pencycuron had no effect on AMF at threshold concentrations and was contact based compared to the other tested fungicides, which were systemic and infiltrated the body of the plant (Buysens, de Boulois, and Declerck 2014; McGrath 2004). Potentially the integration of flurolanil in the host plant made it more hazardous for AMF. Alternatively, contact fungicides applied through foliar spray could be less likely to contaminate the soil (Hage-Ahmed, Rosner, and Steinkellner 2018). Azoxystrobin, like flurolanil, was a systemic fungicide but had lower systemic activity, which could be why it did not have adverse effects on AMF at the threshold level. Pencycuron and flutolanil were species specific fungicides, so the difference in impact could be attributed to increased effectiveness against a fungus similar to AMF species (Buysens, de Boulois, and Declerck 2014). At levels exceeding the threshold all three fungicides had significant negative impact on spore production, mycelium and root growth, and germination. Therefore, carefully choosing the type and quantity of fungicide is crucial to not harm beneficial fungal species.

When the pesticide is applied also greatly impacts the AMF as certain stages of its life cycle are more vulnerable to interference than others. Certain pesticides impeded germination, but multiple studies found that germination was not completely terminated, and that once the pesticide was removed germination was no longer impeded and AMF were able to establish (Buysens, de Boulois, and Declerck 2014; Hage-Ahmed, Rosner, and Steinkellner 2018). In early stages of its lifecycle, AMF had a limited time to find a host and will die if one is not found. Pesticide interference should be avoided in this stage so the AMF and crops can form symbiosis (Hage-Ahmed, Rosner, and Steinkellner 2018). Once established, AMF will be harmed if most of its plant hosts die, so non-selective herbicides can threaten them. They could depend on spores and colonized root fragments should they lack a host, however.

Pesticides vary in effectiveness based on environmental and agricultural conditions, confounding their impact on AMF. The history of the field being tested could greatly affect AMF networks. Practices like tilling and other soil disturbance made AMF colonies more vulnerable to being negatively impacted by pesticides, possibly due to not being as well established as an undisturbed network and thus less resilient. The sheer number of variables involved in studying pesticide’s impact on fungi deeply confound the results of studies.

The amount of exposure to the pesticide impacts to what degree AMF are affected, but it is highly influenced by confounding factors that make it difficult to assess its impact. Practices like tilling and other soil disturbance made AMF colonies more vulnerable to being negatively impacted by pesticides, possibly due to not being as well established as an undisturbed network and thus less resilient (Hage-Ahmed, Rosner, and Steinkellner 2018). The persistence of the pesticide depended greatly on soil condition, including type, pH, moisture, organic matter, and the ability for microflora to degrade substances, all influencing how much exposure the AMF had long-term (Hage-Ahmed, Rosner, and Steinkellner 2018). Furthermore, the type, dose, and application method of pesticide was dependent on the crop being grown, creating even more variation in AMF reaction, and thus confounding studies. In one experiment, going over the recommended dose of a pesticide could either impact the AMF negatively, positively, or not at all, but in another it reduced the effectiveness of symbiosis and the amount of phosphorus transported to the plant (Hage-Ahmed, Rosner, and Steinkellner 2018). Due to the variety of conditions impacting AMF exposure to pesticides, it was difficult to gauge their impact on AMF, and uncertainty in this aspect of studying agricultural AMF held great uncertainty.

Conclusions

The intense networks of factors involved in agriculture systems mean measuring the impact of farming techniques on arbuscular mycorrhizal fungi is difficult. Given the variety of the fungal species involved in AMF networks, it may not be fully possible to have fully accurate generalizations about the impact of farming. With each system of unique combinations of hosts, fungi, and other soil microbiota comes new dynamics to be studied. This is further compounded by soil conditions, nutrient availability, tilling, and potentially many other variables not discussed in this paper. Uncertainty is rampant in this area, particularly as the usefulness of AMF have been discovered only relatively recently. The most evident example is in the realm of pesticides, where the intensity of the variability of results obfuscates broader patterns. However, there is growing evidence that many conventional farming practices such as fertilizers, monocultures, and annuals are damaging to AMF colonies and potentially diminish the benefits they can offer crops. If farming is to become sustainable while still providing enough food for the growing human population, healthier farming practices must be utilized. Though there is uncertainty, there is also great potential once we understand the factors influencing successful AMF symbiosis.
