food and commodities

Leave a reply

Articles about the “commodities market” are a bit brain twisting if you’re not in that biz. For example:

When you buy or sell a financial commodity product by a future on the exchange like the London Metal Exchange, you just pay a fee, an initiation margin call, and then your broker buys on your behalf the full position. If the market moves against you, you pay a bit more margin, and if the market goes in your favor, you get a bit more money from your broker. As the market was starting to go up, the Big Shot position was underwater and the brokers were demanding more money from this position. When the whole market is caught in that situation, we get a short squeeze, which forces everyone who was betting on the downside to buy back their positions because they are facing billions of dollars of margin calls. It got to a point where the market went up 250 percent in about thirty-six hours, with margin calls in the billions. The exchange had no option but to shut down trading. This is a very unusual situation; it only happens once every few decades that a major commodity market has to shut down.

What if a similar situation were to happen in the oil, wheat, or gas market? What would be the consequences for the global economy? Are the commodity traders and the commodity exchanges “too big to fail”? Their failure will bring chaos to the global economy not through the credit channel but through the real economy, perhaps through shortages or crippling high prices.

Phenomenal World (which I never heard of, but this is a transcript of an interview with a Bloomberg reporter)

So this is how the first warnings of a serious global food crisis could come out. So watch the digital equivalent of the business pages.

numbers on vegetarianism in the UK

Leave a reply

Our World in Data articles are always interesting to look at, partly just to see how they visualize data. We also know (at at least I think it is clear) that eating less meat is a key way to reduce our species’ ecological footprint. In the UK, which is probably a reasonable indicator for a range of Anglo-American and European countries, meat eating has declined over time and younger people tend to eat less meat. Around 80% of retirees eat a traditional amount of meat, but only about 50% of young adults (18-24) do.

country-specific warming trends and projections

Leave a reply

Berkeley Earth has country-specific warming trends to date and projections to 2100. The accelerated warming predicted from here on out is startling, particularly if emissions continue to increase. I figure we can use air conditioning, but the biggest issues are going to be loss of places where food can be grown, and massive migration pressure. It seems too late to stop this, but making it less bad than it could be is more urgent than ever.

2021: Year in Review

Leave a reply

As per usual, I’ll list out and link to the stories I chose as the most frightening, most hopeful, and most interesting each month in 2021. Then I’ll see if I have anything smart to say about how it all fits together.

Survey of the Year’s Stories and Themes

Most frightening and/or depressing stories:

  • JANUARY: A China-Taiwan military conflict is a potential start-of-World-War-III scenario. This could happen today, or this year, or never. Let’s hope for the latter. This is a near-term existential risk, but I have to break my own “rule of one” and give honorable mention to two longer-term scary things: crashing sperm counts and the climate change/fascism/genocide nexus.
  • FEBRUARY: For people who just don’t care that much about plants and animals, the elevator pitch on climate change is it is coming for our houses and it is coming for our food and water.
  • MARCH: In the U.S. upper Midwest (I don’t know if this region is better or worse than the country as a whole, or why they picked it), electric blackouts average 92 minutes per year, versus 4 minutes per year in Japan.
  • APRIL: One of the National Intelligence Council’s scenarios for 2040 involves “far-reaching changes designed to address climate change, resource depletion, and poverty following a global food catastrophe caused by climate events and environmental degradation”.
  • MAY: The Colorado River basin is drying out.
  • JUNE: For every 2 people who died of Covid-19 in the U.S. about 1 additional person died of indirect effects, such as our lack of a functioning health care system and safe streets compared to virtually all our peer countries.
  • JULY: The western-U.S. megadrought looks like it is settling in for the long haul.
  • AUGUST: The U.S. is not prepared for megadisasters. Pandemics, just to cite one example. War and climate change tipping points, just to cite two others. Solutions or at least risk mitigation measures exist, such as getting a health care system, joining the worldwide effort to deal with carbon emissions, and as for war, how about just try to avoid it?
  • SEPTEMBER: The most frightening climate change tipping points may not be the ones we hear the most about in the media (at least in my case, I was most aware of melting ice sheets in Greenland and Antarctica, collapse of ocean circulation patterns). The most damaging may be melting permafrost on land and methane hydrates underwater, both of which contain enormous amounts of methane which could set off a catastrophic and unstoppable feedback loop if released in large quantities.
  • OCTOBER: The technology (sometimes called “gain of function“) to make something like Covid-19 or something much worse in a laboratory clearly exists right now, and barriers to doing that are much lower than other types of weapons. Also, because I just couldn’t choose this month, asteroids can sneak up on us.
  • NOVEMBER: Freakonomics podcast explained that there is a strong connection between cars and violence in the United States. Because cars kill and injure people on a massive scale, they led to an expansion of police power. Police and ordinary citizens started coming into contact much more often than they had. We have no national ID system so the poor and disadvantaged often have no ID when they get stopped. Everyone has guns and everyone is jumpy. Known solutions (safe street design) and near term solutions (computer-controlled vehicles?) exist, but are we going to pursue them as a society? I guess I am feeling frightened and/or depressed today, hence my choice of category here.
  • DECEMBER: Mass migration driven by climate change-triggered disasters could be the emerging big issue for 2022 and beyond. Geopolitical instability is a likely result, not to mention enormous human suffering.

Most hopeful stories:

  • JANUARY: Computer modeling, done well, can inform decisions better than data analysis alone. An obvious statement? Well, maybe to some but it is disputed every day by others, especially staff at some government regulatory agencies I interact with.
  • FEBRUARY: It is possible that mRNA technology could cure or prevent herpes, malaria, flu, sickle cell anemia, cancer, HIV, Zika and Ebola (and obviously coronavirus). With flu and coronavirus, it may become possible to design a single shot that would protect against thousands of strains. It could also be used for nefarious purposes, and to protect against that are ideas about what a biological threat surveillance system could look like.
  • MARCH: I officially released my infrastructure plan for America, a few weeks before Joe Biden released his. None of the Sunday morning talk shows has called me to discuss so far. Unfortunately, I do not have the resources of the U.S. Treasury or Federal Reserve available to me. Of course, neither does he unless he can convince Congress to go along with at least some portion of his plans. Looking at his proposal, I think he is proposing to direct the fire hoses at the right fires (children, education, research, water, the electric grid and electric vehicles, maintenance of highways and roads, housing, and ecosystems. There is still no real planning involved, because planning needs to be done in between crises and it never is. Still, I think it is a good proposal that will pay off economically while helping real people, and I hope a substantial portion of it survives.
  • APRIL: Giant tortoises reach a state of “negligible senescense” where they simply don’t age for a long time. Humans are distant relatives of giant tortoises, so maybe we can aspire to this some day. They are not invulnerable to injury and disease.
  • MAY: An effective vaccine for malaria may be on the way. Malaria kills more children in Africa every year than Covid-19 killed people of all ages in Africa during the worst year of the pandemic. And malaria has been killing children every year for centuries and will continue long after Covid-19 is gone unless something is done.
  • JUNE: Masks, ventilation, and filtration work pretty well to prevent Covid transmission in schools. We should learn something from this and start designing much healthier schools and offices going forward. Design good ventilation and filtration into all buildings with lots of people in them. We will be healthier all the time and readier for the next pandemic. Then masks can be slapped on as a last layer of defense. Enough with the plexiglass, it’s just stupid and it’s time for it to go.
  • JULY: A new Lyme disease vaccine may be on the horizon (if you’re a human – if you are a dog, talk to your owner about getting the approved vaccine today.) I admit, I had to stretch a bit to find a positive story this month.
  • AUGUST: The Nordic welfare model works by providing excellent benefits to the middle class, which builds the public and political support to collect sufficient taxes to provide the benefits, and so on in a virtuous cycle. This is not a hopeful story for the U.S., where wealthy and powerful interests easily break the cycle with anti-tax propaganda, which ensure benefits are underfunded, inadequate, available only to the poor, and resented by middle class tax payers.
  • SEPTEMBER: Space-based solar power could finally be in our realistic near-term future. I would probably put this in the “interesting” rather than “hopeful” category most months, but I really struggled to come up with a hopeful story this month. I am at least a tiny bit hopeful this could be the “killer app” that gets humanity over the “dirty and scarce” energy hump once and for all, and lets us move on to the next layer of problems.
  • OCTOBER: The situation with fish and overfishing is actually much better than I thought.
  • NOVEMBER: Urban areas may have some ecological value after all.
  • DECEMBER: Covid-19 seems to be “disappearing” in Japan, or at least was before the Omicron wave. Maybe lessons could be learned. It seems possible that East Asian people have at least some genetic defenses over what other ethnic groups have, but I would put my money on tight border screening and an excellent public health care system. Okay, now I’m starting to feel a bit depressed again, sitting here in the U.S. where we can’t have these nice things thanks to our ignorant politicians.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

  • JANUARY: There have been fabulous advances in note taking techniques! Well, not really, but there are some time honored techniques out there that could be new and beneficial for many people to learn, and I think this is an underappreciated productivity and innovation skill that could benefit people in a lot of areas, not just students.
  • FEBRUARY: At least one serious scientist is arguing that Oumuamua was only the tip of an iceberg of extraterrestrial objects we should expect to see going forward.
  • MARCH: One study says 1-2 days per week is a sweet spot for working from home in terms of a positive economic contribution at the national scale. I think it is about right psychologically for many people too. However, this was a very theoretical simulation, and other studies attempting to measure this at the individual or firm scale have come up with a 20-50% loss in productivity. I think the jury is still out on this one, but I know from personal experience that people need to interact and communicate regularly for teams to be productive, and some people require more supervision than others, and I don’t think technology is a perfect substitute for doing these things in person so far.
  • APRIL: Hydrogen fuel cells may finally be arriving. Not so much in the U.S., where we can’t have nice things.
  • MAY: I learned about Lawrence Kohlberg, who had some ideas on the use of moral dilemmas in education.
  • JUNE: The big U.S. government UFO report was a dud. But what’s interesting about it is that we have all quietly seemed to have accepted that something is going on, even if we have no idea what it is, and this is new.
  • JULY: “Cliodynamics” is an attempt at a structured, evidence-based way to test hypotheses about history.
  • AUGUST: Ectogenesis is an idea for colonizing other planets that involves freezing embryos and putting them on a spaceship along with robots to thaw them out and raise them. Fungi could also be very useful in space, providing food, medicine, and building materials.
  • SEPTEMBER: Philip K. Dick was not only a prolific science fiction author, he also developed a comprehensive theory of religion which could possibly even be the right one. Also, possibly related but not really, if there are aliens out there they might live in creepy colonies or super-organisms like ants or termites.
  • OCTOBER: I thought about how to accelerate scientific progress: “[F]irst a round of automated numerical/computational experiments on a huge number of permutations, then a round of automated physical experiments on a subset of promising alternatives, then rounds of human-guided and/or human-performed experiments on additional subsets until you hone in on a new solution… [C]ommit resources and brains to making additional passes through the dustbin of rejected results periodically…” and finally “educating the next generation of brains now so they are online 20 years from now when you need them to take over.” Easy, right?
  • NOVEMBER: Peter Turchin continues his project to empirically test history. In this article, he says the evidence points to innovation in military technologies being driven by “world population size, connectivity between geographical areas of innovation and adoption, and critical enabling technological advances, such as iron metallurgy and horse riding“. What does not drive innovation? “state-level factors such as polity population, territorial size, or governance sophistication“. As far as the technologies coming down the pike in 2022, one “horizon scan” has identified “satellite megaconstellations, deep sea mining, floating photovoltaics, long-distance wireless energy, and ammonia as a fuel source”.
  • DECEMBER: Time reminded us of all the industries Elon Musk has disrupted so far: human-controlled, internal-combustion-fueled automobiles; spaceflight; infrastructure construction (I don’t know that he has really achieved any paradigm shifts here, but not for lack of trying), “artificial intelligence, neurotechnology, payment systems and cryptocurrency.” I’m not sure I follow a couple of these, but I think they missed satellites.

Continuing Signs of U.S. Relative Decline

Signs of U.S. decline relative to our peer group of advanced nations are all around us. I don’t know that we are in absolute decline, but I think we are now below average among the most advanced countries in the world. We are not investing in the infrastructure needed in a modern economy just to reduce friction and let the economy function. The annual length of electric blackouts in the U.S. (hours) compared to leading peers like Japan (minutes) is just one telling indicator. In March, I looked at the Build Back Better proposal and concluded that it was more like directing a firehose of money at a range of problems than an actual plan, but I hoped at least some of it would happen. My rather low but not zero expectations were met, as some limited funding was provided for “hard infrastructure” and energy/emissions projects, but little or nothing (so far, as I write this) to address our systemic failures in health care, child care, or education. The crazy violence on our streets, both gun-related and motor vehicle-related, is another indicator. Known solutions to all these problems exist and are being implemented to various extents by peer countries. Meanwhile our toxic politics and general ignorance continue to hold us back. Biden really gave it his best shot – but if this is our “once in a generation” attempt, we are headed down a road where we will no longer qualify as a member of the pack of elite countries, let alone its leader.

The Climate Change, Drought, Food, Natural Disaster, Migration and Geopolitical Instability Nexus

2021 was a pretty bad year for storms, fires, floods, and droughts. All these things affect our homes, our infrastructure, our food supply, and our water supply. Drought in particular can trigger mass migration. Mass migration can be a disaster for human rights and human dignity in and of itself, and managing it effectively is difficult even for well-intentioned governments. But an insidious related problem is that migration pressure can tend to fuel right wing populist and racist political movements. We see this happening all over the world, and the situation seems likely to get worse.

Tipping Points and other Really Bad Things We Aren’t Prepared For

We can be thankful that nothing really big and new and bad happened in 2021. My apologies to anyone reading this who lost someone or had a tough year. Of course, plenty of bad things happened to good people, and plenty of bad things happened on a regional or local scale. But while Covid-19 ground on and plenty of local and regional-scale natural disasters and conflicts occurred, there were no new planetary-scale disasters. This is good because humanity has had enough trouble dealing with Covid-19, and another major disaster hitting at the same time could be the one that brings our civilization to the breaking point.

So we have a trend of food insecurity and migration pressure creeping up on us over time, and we are not handling it well even given time to do so. Maybe we can hope that some adjustments will be made there to get the world on a sustainable track. Even if we do that, there are some really bad things that could happen suddenly. Catastrophic war is an obvious one. A truly catastrophic pandemic is another (as opposed to the moderately disastrous pandemic we have just gone through.) Creeping loss of human fertility is one that is not getting much attention, but this seems like an existential risk if it were to cross some threshold where suddenly the global population starts to drop quickly and we can’t do anything about it. Asteroids were one thing I really thought we didn’t have to worry much about on the time scale of any human alive today, but I may have been wrong about that. And finally, the most horrifying risk to me in the list above is the idea of an accelerating, runaway feedback loop of methane release from thawing permafrost or underwater methane hydrates.

We are almost certainly not managing these risks. These risks are probably not 100% avoidable, but since they are existential we should be actively working to minimize the chance of them happening, preparing to respond in real time, and preparing to recover afterward if they happen. Covid-19 was a dress rehearsal for dealing with a big global risk event, and humanity mostly failed to prepare or respond effectively. We are lucky it was one we should be able to recover from as long as we get some time before the next body blow. We not only need to prepare for much, much worse events that could happen, we need to match our preparations to the likelihood of more than one of them happening at the same time or in quick succession.

Technological Progress

Enough doom and gloom. We humans are here, alive, and many of us are physically comfortable and have much more leisure time than our ancestors. Our social, economic, and technological systems seem to be muddling through from day to day for the time being. We have intelligence, science, creativity, and problem solving abilities available to us if we choose to make use of them. Let’s see what’s going on with technology.

Biotechnology: The new mRNA technology accelerated by the pandemic opens up potential cures for a range of diseases. We need an effective biological surveillance system akin to nuclear weapons inspections (which we also need) to make sure it is not misused (oops, doom and gloom trying to creep in, but there are some ideas for this.) We have vaccines on the horizon for diseases that have been plaguing us for decades or longer, like malaria and Lyme disease. Malaria kills more children worldwide, year in and year out, than coronavirus has killed per year at its peak.

Promising energy technologies: Space based solar power may finally be getting closer to reality. Ditto for hydrogen fuel cells in vehicles, although not particularly in the U.S. (I’m not sure this is preferable to electric vehicles for everyday transportation, but it seems like a cleaner alternative to diesel and jet fuel when large amounts of power are needed in trucking, construction, and aviation, for example.)

Other technologies: We are actually using technology to catch fish in more sustainable ways, and to grow fish on farms in more sustainable ways. We are getting better at looking for extraterrestrial objects, and the more we look, the more of them we expect to see (this one is exciting and scary at the same time). We are putting satellites in orbit on an unprecedented scale. We have computers, robots, artificial intelligence of a sort, and approaches to use them to potentially accelerate scientific advancements going forward.

The State of Earth’s Ecosystems

The state and trends of the Earth’s ecosystems continue to be concerning. Climate change continues to churn through the public consciousness and our political systems, and painful as the process is I think our civilization is slowly coming to a consensus that something is happening and something needs to be done about it (decades after we should have been able to do this based on the evidence and knowledge available.) When it comes to our ecosystems, however, I think we are in the very early stages of this process. This is something I would like to focus on in this blog in the coming year. My work and family life are busy, and I have decided to take on an additional challenge of becoming a student again for the first time in the 21st century, but somehow I will persevere. If you are reading this shortly after I write it in January 2022, here’s to good luck and prosperity in the new year!

water, energy, and food in macroeconomic models

Leave a reply

Here’s an article on how water, energy, and food fit into macroeconomic models. My basic understanding is that traditionally, they don’t. Production functions focus on labor and capital because these are assumed to explain most of the output, and including water, energy, raw material, and even land prices does not make enough difference to bother with. So the methods exist, but economists generally don’t bother because historical data shows these things don’t make a difference. We have certainly seen short-term and regional price shocks in food and energy that have affected economies. We haven’t really seen a sustained, long-term rise in prices of water, energy, or food, in fact the long term trend has been clearly the opposite. Will climate change begin to reverse this at some point? Or is it already happening but our technology is keeping up? Or is it happening slowly, we are adjusting, but the system is becoming more fragile and we are headed for a sudden panic at some point? Like dead wood building up in a forest – the forest may look okay for a long time, and then one day there is a spark, followed by an intense crisis, and then you are left with ashes…

Critical Reflections on Water-Energy-Food Nexus in Computable General Equilibrium Models: A Systematic Literature Review

The paper analyses how the Water-Energy-Food Nexus is treated in Computable General Equilibrium (CGE) models, discussing their design, importance and possible ways of improvement. The analysis of their structure is critical for evaluating their potential efficiency in understanding the Nexus, which will be particularly effective for gauging the importance of the topic, the reciprocal dependency of its elements and the expected macroeconomic, demographic and climatic pressures that will act on its components. General equilibrium models can be useful devices to this end, as they are specifically built to track interdependencies and transmission effects across sectors and countries. Nevertheless, the review showed that most CGEs in the literature struggle to represent the competing water uses across sectors and, in particular, those concerning the energy sector. Therefore, it highlights the need to resolve this issue as a necessary step toward improving future research.

U.S. topsoil

Leave a reply

A study published in Nature says the U.S. “corn belt” has lost something like 35% of its topsoil. Sounds concerning, and I have heard dramatic claims like “the world only has 50 years of topsoil left. I also just find it sad to think that the topsoil was built up by the prairies over the millennia, and we have mined much of it into oblivion in a few short industrial generations. But this article also puts the loss in terms of crop yields at around 6%, which doesn’t sound so dramatic. This makes me think we are relying largely on agricultural chemicals rather than nutrients in the soil itself. Maybe it would actually make more sense to intensify industrial agricultural in some areas or even indoors, contain the impacts, and restore some of those prairies.

April 2021 in Review

Most frightening and/or depressing story: One of the National Intelligence Council’s scenarios for 2040 involves “far-reaching changes designed to address climate change, resource depletion, and poverty following a global food catastrophe caused by climate events and environmental degradation”.

Most hopeful story: Giant tortoises reach a state of “negligible senescense” where they simply don’t age for a long time. Humans are distant relatives of giant tortoises, so maybe we can aspire to this some day. They are not invulnerable to injury and disease.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: Hydrogen fuel cells may finally be arriving. Not so much in the U.S., where we can’t have nice things.

The National Intelligence Council’s Global Trends 2040

Leave a reply

Every four years, or early in each U.S. presidential administration, the National Intelligence Council publishes a scenario report. I had to look up what the council actually is, and basically it is an organization reporting to the Director of National Intelligence, who reports to the President and is sort of but not really in charge of the U.S. “intelligence community”, which sprawls across various military and civilian agencies with their own organizational structures.

Since this is a U.S. government report and not copyrighted, I can copy and paste as much of it as I want. Here are the five scenarios they came up with:

RENAISSANCE OF DEMOCRACIES: The world is in the midst of a resurgence of open democracies led by the United States and its allies. Rapid technological advancements fostered by public-private partnerships in the United States and other democratic societies are transforming the global economy, raising incomes, and improving the quality of life for millions around the globe. In contrast, years of increasing societal controls and monitoring in China and Russia have stifled innovation.

A WORLD ADRIFT: The international system is directionless, chaotic, and volatile as international rules and institutions are largely ignored. OECD countries are plagued by slower economic growth, widening societal divisions, and political paralysis. China is taking advantage of the West’s troubles to expand its international influence. Many global challenges are unaddressed.

COMPETITIVE COEXISTENCE: The United States and China have prioritized economic growth and restored a robust trading relationship, but this economic interdependence exists alongside competition over political influence, governance models, technological dominance, and strategic advantage. The risk of major war is low, and international cooperation and technological innovation make global problems manageable.

SEPARATE SILOS: The world is fragmented into several economic and security blocs of varying size and strength, centered on the United States, China, the EU, Russia, and a few regional powers, and focused on self-sufficiency, resiliency, and defense. Information flows within separate cyber-sovereign enclaves, supply chains are reoriented, and international trade is disrupted. Vulnerable developing countries are caught in the middle.

TRAGEDY AND MOBILIZATION: A global coalition, led by the EU and China working with NGOs and revitalized multilateral institutions, is implementing far-reaching changes designed to address climate change, resource depletion, and poverty following a global food catastrophe caused by climate events and environmental degradation. Richer countries shift to help poorer ones manage the crisis and then transition to low carbon economies through broad aid programs and transfers of advanced energy technologies.

Everything above is a quote by the way. I couldn’t get horrible, terrible, no good very bad WordPress editor to make them look like quotes, even using the HTML editor.

Anyway, there is a lot of doom and gloom here. I am oftentimes all about doom and gloom, especially when others are feeling optimistic, but the contrarian in me wants to think that now that almost everyone is feeling doomy gloomy, maybe the reality will not be so bad. Certainly the major food crisis above gets my attention. A major war, terrorist attack, major natural or industrial disaster, or combination of these could obviously be devastating. Smaller-scale disasters and conflicts are pretty much guaranteed, and refugee flows from poorer to richer nations are going to become an issue more and more. It is hard to see our natural environment coming under less pressure in the coming 20 years, and hard to imagine much progress toward a peaceful world government and equality on a global scale.

On the other hand, much of Europe and Asia have the managed economy thing reasonably figured out, where the capitalist economy is able to grow while the government collects taxes and provides services people need, like health care, education, and retirement. Cynical politicians in Europe and North America may figure out that the refugee pressure they are going to face will be catastrophic and that helping potential refugees in their home countries is a win-win for everyone. The world really has done pretty well with the food situation so far, and let’s assume this will continue to be a priority and that competent visionary people will remain in charge of that. Medical breakthroughs seem very likely over the next 20 years – for example, widespread cures for cancer, diabetes, HIV, and other dread diseases seem like they might be on the horizon. The population explosion will start to slow down. And let’s just say we avoid major war, plagues, or famines through a combination of competence and luck. Things really could be okay, and a generation of children could grow up in a relatively stable, sheltered, prosperous situation much as the majority of today’s middle-aged adults in developed countries did. Some of those children will be the problem solvers of tomorrow who come up with additional breakthroughs and incremental progress.

There, I just talked myself into not being quite so doomy gloomy.

yes, you can eat Cicadas

Leave a reply

The bulk of the Brood X cicadas are likely to come out in May (if 2004 is a good guide to what to expect) and be centered around D.C. and Baltimore. The edge of the blob just touches Philadelphia, and there are scatterings in southern and Central Pennsylvania, Ohio, Indiana, Tennessee and Georgia. I wonder how they get scattered the way they do – do they start out everywhere and then local populations gradually go extinct over time? Besides a clear map and an empirical probability density function (but they don’t call it that, not wanting to scare readers!), this Washington Post article reminded me that the Cicada swarm is actually made up of three similar but different species. That also is weird and interesting.

Also, here is a cicada cookbook from the University of Maryland. I have tried fried crickets in Asia but I don’t think I can bring myself to try Cicadas. As the into to the cookbook points out though, shrimp and crayfish are basically bugs that we westerners eat, so your ick factor is mostly just a matter of cultural conditioning. The cookbook also has this interesting comparison of protein in insects vs. other animals we humans like to eat:

Many people all over the world eat insects and other arthropods both as a delicacy and staple. This is sensible because insects are nutritious. Insects provide as much protein pound per pound as lean beef. For example, every 100 gram serving of each, termites provide 617 calories of energy while lean ground beef gives 219 and cod gives 170 (3). Although their amino acid content is not as well-balanced for human nutrition, this can be easily corrected by including fiber and other plant proteins into your diet. Insects are also a good source of minerals and some vitamins, especially for people who have limited access to other animal proteins.

University of Maryland

So termites sound like a pretty good survival food. Even if you live in some wasteland where nothing else will grow, there is likely some wood around that you could feed to them. You can then feed them to chickens or rats if you want, but it may be most efficient to just eat them if you can handle it. I don’t think I handle it – termites are in the cockroach family, I while I can handle the crickets for sale in Asian street markets, I cannot handle the “water bugs” which are basically cockroaches. But maybe if someone can grind them into a flour or paste I can use to thicken my soup, it could be a nutritious supplement and I might not have to think about it so much.
