Basics

A Book by David Denkenberger and Joshua M. Pearce
Essentially Can Humanity Feed The Survivors After Some Sort of Event That Blocks Out The Sun
So Asteroid/Comet Impact, Volcano/Supervolcano, or even Nuclear Fall/Winter
It mainly suggested:
- Power-to-Food
- Methane-to-Food (Via "Natural Gas" )
- Feeding Various Livestock the Products of the Above Two Processes and/or Dead Biomass From What Once Were Forests etc
  - Cattle (Can turn cellulose into meat and dairy)
  - Insects (Produce High Protein From the Above, and even Waste)
  - Rats
  - Mushrooms
These novel solutions are required because, unlike a Hurricane or other typical natural disaster, the whole globe is effected, so other regions can not be counted on for Aid. Also the resulting food shortages will last for years to decades; far too long to make Food Storage (Humanity's Primacy Method Since the Early River Valley Civilizations/The Invention of Agriculture) not reasonably viable
- Also unlike food storage, it is meant to feed all the population, not those in some bunker with supplies
All in all it seems like a really interesting read, and honestly not too bad of something for various Government/NGO groups to invest in setting up!
Also even outside the obscenely unlikely events, i think it's points may be of use for application to Power-to-Foods / permaculture theory and practice as well

- This was especially interesting, because we could be eating *only* Chicken Deep Fried in Algae Oil, and Natural Gas Beer or some shit, but this paper is going into how you would go about making it actually a sustainable long term diet, not just something that can keep you alive (I remember in my AP Human Geography Class, we discussed how Protein–Energy Malnutrition due to consumption of mainly just Grain Staple Crops / Bread due to poverty/what's locally available is a larger issue in some less developed economies moreso than actual starvation) so i'd imagine something like that or maybe something like Protein poisoning in this case due to piles of Microbial Protein and Animal Protein but not many grains so perhaps carbs would become scarce! All in all really neat stuff - Eric

(The Appropedia Page for) "Nutrition in Abrupt Sunlight Reduction Scenarios: Envisioning Feasible Balanced Diets on Resilient Foods" has a Great Diagram.
- It was ~14mb if i remember correctly, i compressed it to ~1.25 mb or so but that still seems above the limit
- I'll just provide the link Here
  - If anyone feels like and is capable of embeding it, feel free!
The articles for the original book have a diagram, but it's web is a bit hard to follow and the design isn't too aesthetically pleasing (at least in my opinion)
