AUTHOR'S INTERLUDE: Agriculture

Hi. Teeny tiny author's interlude here.

As I've been writing this fic, I've found myself thinking about a lot of things. Mostly, the logistical practicalities of trying to grow enough to eat in the wasteland, and the culture surrounding those practicalities. If that doesn't sound interesting to you, you don't have to read this little interlude. Just skip ahead to the next section.

Let's start with the napkin maths.

We're going to be working out a couple things. First, the thing I'm sure we've all wondered: can you really feed that many people with what space they give you in the canon settlements?

To do this we need to find: A) the amount of energy people need, yearly, B) the amount of energy the crops give you depending on the space they take up, C) how many nutrients you need, and what kinds of crops give those nutrients, D) how much space those crops take up, and E) the equivalent amount of space in-game available at the settlements.

Also since we're limited to averages, our results can only be considered an estimate.

A) Population

Vanilla game, maxed out Charisma, you have 23 settlements with up to 20 settlers each. So 460 people - call that the realistic average, because Starlight could almost certainly fit more, and Hangman's would be lucky to squeeze in 10.

Here's our process:

  1. Find the recommended average adult daily intake*. In Australia, that's 8700kj.
  2. Find the yearly intake for the average adult. 8700 x 365 = 3175500kj
  3. Multiply that by 460 to find the needed kj for our maximum population. 460 x 3175500 = 1460730000kj

*Some of these people will be robots, who do not need to eat. We're counting them anyway because they still cost resources and energy to maintain, and we can say the allotted food to them is instead being traded for fuel or spare parts.

B) Energy

Then we go over the crops in-game, to find out what we're working with to hit that energy goal. Essentially, what energy do our available crops actually give us?

To do this, we're going to try to find the energy output in kj per square metre of each crop, per year, because that will help us with the next section.

Here's our process:

  1. Find out how many of each crop grow in a square metre of soil, per yearly harvest.
  2. Find out how many grams per individual unit of crop.
  3. Use (1) and (2) to determine how many grams produced per square metre.
  4. Find out how many kj per 100g.
  5. Use (3) and (4) to determine the total # of kj produced by square metre of crop, per year. (Divide the kj by 100 to get the 'per gram' #, and times that by (3)).
  6. The final number SHOULD BE the yearly energy output in kj for that particular crop, in one square metre of soil.

Because this is messy, we're gonna do it as a table. For space reasons, we're shortening 'per square metre of soil' to '*sqm/s'.

Carrots Corn* Gourd Melon Mutfruit Razorgrain Tarberry Tato
# Crop harvested *sqm/s 40 1 plant / 1-3 ears at ~ 1/2 cup corn / ear. 1 1 1 tree / 20 fruit * * 1-2 plants / ~20 fruit per plant (~15 fruit total)
Grams per crop: 60g (1 carrot) ~140g (per cup of kernels) / 70g - 210g (per plant) 1000g 1000g 60g (1 fruit) * * 125g (1 fruit)
Grams harvested *sqm/s 2400g *sqm/s ~140g *sqm/s 1000g *sqm/s 1000g *sqm/s 1200g *sqm/s ~18.1g *sqm/s 1500g *sqm/s 1875g *sqm/s
kj per 100g ~112kj / 100g ~370kj / 100g ~155kj / 100g ~91kj / 100g ~156kj / 100g ~1269kj / 100g ~1288kj / 100g ~76kj / 100g
Total kj *sqm/s per year. 2688 kj 518 kj 1550 kj 910 kj 1872 kj 229 kj 19320 kj 1425 kj

*I don't have the resources to find this for bulk crops, so I'm using other ppl's research. It's for a fanfic. It's okay.

C) Nutrients

Now for nutrients. Let's have a look at that.

Carbohydrates

Sugars

Fats

Protein

Salt/sodium and potassium

Vitamins and minerals (micronutrients)

Now, because I'm insane, I can't help but notice we're missing some crop staples. To make up for this, we're going to invent some new, fake seeds for Ozzie to grow to help fill these gaps in nutrition.

Animal-wise, we're also missing honey (bee-hives) (sugar), fish (fat, protein), chickens (fat, protein, nutrients), game (hunting)(protein, nutrients), and some larger source of protein, like deer or cows. And if you thought that plants were complex, animal husbandry is a whole other beast. For animals, we'll say 'Fire bees' (guess what the sting feels like), 'Rad-fin' (fish lol), 'Rad-chickens' (basic is best), and maybe 'Geep' (goat / sheep hybrid).

From here we're gonna do two things: we're gonna do the same calculations we did for the canon crops for these new additions. Canon explanation for the fic is that Ozzie's been prepping for years. We'll do that on another page, maybe, to save space... nah, what am I saying, you've scrolled this far. You'll keep scrolling. You're in this with me, now.

Come, take my hand. Let's be insane together.

'Radyams' 'Mungoss Beans' 'Zuch-fruit' 'Applecherries' 'Wazelnuts' 'Sunflowers' 'Oilberries' 'Brassica'
Crop yeild *sqm/s 4000g ~350g 1500g 1700 300g (low end) 200g 1000g 1200g
kj per 100g ~400kj / 100g ~108kj / 100g ~72kj / 100g ~296kj / 100g ~2605kj / 100g ~2258kj / 100g ~842kj / 100g ~101kj / 100g
Total kj *sqm/s per year. 16000 kj 378 kj 1080 kj 5032 kj 7815 kj 4516 kj 8420 kj 1212 kj

So now we can find out how much space we need to feed a single person for a year on a balanced diet.

We'll do this using the solution from section A. The amount of kj needed (ballpark) to feed the average adult for a year, 8,700kj daily, x 365 = 3,175,500kj.

More graphs: this time we're trying to work out how much of this amount is generally comprised of each of the food groups. So:

Percentage of yearly kj Crops Available
Carbohydrates: 45-75% 1,428,975kj - 2,381,625kj Radyams, corn, razorgrain, tarberries, mungoss beans, zuchfrut, brassicas.
Sugars: 0-10% 0kj - 317,550kj Mutfruit, tarberries, applecherries, brassicas.
Fats: 15-30% 476,325kj - 952,650kj (max saturated: 317,550kj; max trans 31,755kj) Unsaturated(any%): rad-fin, wazel nuts, sunflower and olive oils. / Saturated: fatty meat, butter, cream, cheese, lard. / Trans: Brahmin/geep meat and dairy.
Protein: 10-15% 317,550kj - 476,325kj Crickets/grasshoppers, wazelnuts, rad-fin, rad-chickens + eggs, radstags, lizards (iguanas), squirrels (and other game), radscorpions, deathclaws.
Vitamins/minerals: Unspecified (1%) ~31,755kj Carrots, gourd, melons, mutfruit, tarberry, tato, radyams, mungoss beans, zuch-fruit, applecherries, wazelnuts, brassica.

Note: skipping over salt and potassium because those don't factor into crop space right now. Going to try to remember to do maths seperate for animals and byproducts.

D) Crop space

Now we're going to split the food into it's various nutritionary groups, and then determine the space needed to grow enough crops to feed one person on a balanced diet. That way the system is modular, and can be expanded to theoretically any population size.

Below, we're going to work out how much of each crop would be needed to fit the maximum kj for that food group. In other words, if you were eating radyams alone, how many square metres of radyams you'd need.

Carbohydrates Radyams Corn Razorgrain Tarberries Mungos beans Zuchfruit Brassicas
1,428,975kj total 89.31 2758.63 6240 73.96 3780.35 1323.125 1179.02
2,381,625kj total 148.85 4597.73 10400.10 123.27 6300.59 2205.20 1965.03

Sugars Mutfruit Tarberries Applecherries Brassicas
317,550kj total 169.63 16.43 63.10 262

Unsaturated Fats Wazelnuts Sunflowers Oilberries
476,325kj total 60.95 105.47 56.57
952,650kj total 121.90 210.94 113.14

Note: Remember to work out fish + saturated fats seperately.

Vitamins / Minerals Car. Gourd Mel. Mutfr. T.brry Tat. R.yams M. bean Zuchfr. Ap.cherr. W.nuts Bras.
31,755 kj total 11.81 20.48 34.89 16.96 1.64 22.28 1.98 84 29.4 6.31 4.06 26.2

Now let's knock that down into minimum, average, and maximum because I'm lazy. These final numbers are 'per person' for the record. Minimum is a very unhealthy and unpleasant existence - but you wont die. You'll just want to. The maximum is a preposterous luxury no-one needs.

Minimum Absolute Average Maximum
Carbs (Radyams) 89.31 2941.79 (Razorgrain) 10400.10
Sugars (None) 127.79 (Brassicas) 262
Unsaturated Fats (Oilberries) 56.57 111.49 (Sunflowers) 210.94
Vitamins (None) 21.66 (Melons) 34.89
Total 146.38 3202.73 10907.93

So the average is about 8 basketball courts / person, give or take.

For 20 people, that comes out (64054.6) square metres - or about four of these bad boys.

E) Game - Real Life Equivalents

Now is the part where I kill Todd Howard.

You see, in order for these numbers to be meaningful, we need to work out how in-game space translates to real-world measurements. Unfortunately, Fallout 4 has an inaccurate map! There is no single measurement that was used for all locations!

I could tie myself into knots trying to find a universal measurement anyway, but I think a better solution is to just use Fenwick park (Diamond City) as the scale of reference. It's an in-game equivalent to a real world place, it has easily referenced dimensions, it'll do. (If anyone wants to use something else as reference, you're more than welcome to plug the numbers into that instead. If you do, email me! I'd like to see if there's any difference, at the end of the day.)

A bit of very clumsy maths tells me the field is... (94.5m x 92m = 8694 metres squared, or 93,581 square ft)! The original Fenway park, like the area of the block and the stands and the building, that's apparently 365,000 square feet (or 33,900 square meters), so it's very possible.

I'm not measuring the full 'accurate' area of the field for two reasons. First, the most accurate way of measuring with those irregular boundaries... is, uh. Calculus.

Which I can't do.

Believe me, if I could, I would. The need to know is a terrifying thing. Second reason: I'm planning to use the in-game distances of the bases as a reference anyway, so it'll come to the same thing if I just do it like a square. However, the only way I can think of to do it is...

...walk that distance in-game, and count the steps.

Simple enough, right? Hahahahaha... if that's my only recourse, that means I would need to do that... for every settlement. But I've looked and looked, and I can't find another way to measure that works. God, it's going to take so long. That's 23 settlements. Some have really weird boundaries! I can't do calculus - I'm just gonna have to walk in a straight line, and do my best to be as accurate as I can!

Maths time. For Diamond City, we're going to assume (perhaps optimistically) that the distance is accurate to the pre-war park. If you didn't know, Diamond City has the bases scattered around its city plan, and if you run through all of them in a certain time, you get an achievement. I walked the distances multiple times to make sure I got an accurate average. I also tried to take as direct a route as possible.

In Power Armor steps, it is:

The distance from home to third is just ever so slightly longer. Still 18 steps, but just... almost that little bit more. As we look at the real life measurements, we get:

Putting that together (real life divided by in-game measurements, to see equivalent of one step to real life distance), we get:

Given those come out to about the same, we can call that a pretty accurate measurement.

Thus, to find the area equivalent, we only need to times steps to see how it measures up.

That's some super-compressed dimensions. These measurements seem like a lot. The actual question is... will they be enough?

You know what this means now, don't you. We need to find the area in steps of all the settlements, from Hangman's to Spectacle. We're going to do this as accurately as we can, using the method for irregular shapes where you break it down into rectangles or triangles, and use the formulas seperately, and add it all together. It's not going to be perfect, but it's going to give us a basic idea of the space we're working with, since once again, I can't do calculus.

Welp, it won't get any more done by avoiding it. I might just do the Sector 1 settlements, right now, and fill in the rest as I get time.

Basic dimensions in 'steps' Area in 'steps' squared Area equivalent in real life metres squared Notes
Abernathy Farm (19 x 55) 1045 27,170 Big rectangle.
Outpost Zimonja (13 x 21) + half(22 x 6) + (8 x 7) 395 10,270 Main rectangle + back field triangle + little entrance rectangle.
Red Rocket Truck Stop (21 x 37) + (19 x 3) + half(20 x 5) 884 22,984 Main rectangle + Concord side hill + road area.
Sanctuary Hills (90 x 80) 7200 187,200 Kept getting stuck on trees and shit. Given the size of the 'island' it's fair to assume bigger rather than smaller, so I got a bit sloppy measuring it out. It's good enough to know what we're working with.
Starlight Drive-in (31 x 47) 1457 37,882 I love when the build area is basically a rectangle.
Sunshine Tidings Co-op (44 x 38) 1672 43,472 Once again getting lazy with it. It's not like they'd be limited by boundaries in real life - those exist in the game so cells are loaded properly.
Tenpines Bluff (28 x 16) 448 11,684 More than you'd think, but still small, right?

Conclusion

Now we can finally work out the actual population limits for available space, based on how much food those people would need, and how much it's possible to grow. For reference, 20 ppls worth of food on minimum rations is 2927.6 square metres, average is 63,621.4, and maximum is 217,460.8 square metres. Check the table in section E for how much space is available at each.

20 Settlers Min Rations Avg Rations Max Rations Comfortable Average # People
Abernathy Farm Yes. No. No. 8
Outpost Zimonja Yes. No. No. 3
Red Rocket Truck Stop Yes. No. No. 7
Sanctuary Hills Yes. Yes. No. 58
Starlight Drive-in Yes. No. No. 11
Sunshine Tidings Co-op Yes. No. No. 13
Tenpines Bluff Yes. No. No. 3

Fuck me, someone check my maths on Sanctuary. Surely it's not actually that big, that can't be right.

But wait, have I... have I done it? Is the maths part done - at least for now? Fuck me, I think it is.

And if we say supply lines are a thing, this means the comfortable average of all sector one settlements is... 14 people each. Cool.


What's the point?

By working out the actual space needed for people to live - or at least realistic estimates - the fic feels more grounded for me, and hopefully for anyone reading it too. But mostly for me.

The real answer is that the Question wouldn't leave me alone. The Question is 80% of my writing motivation, sometimes. It took hold of my mind. My skull was a cave with great burning letters on the wall spelling out the Question, in all caps - and I just couldn't stop until I had the answer: 'HOW DOES IT WORK?'

So this definitely won't be the only interlude where I go into detail to try and answer it - it was agriculture, this time, but it might be irrigation or culture or economy next time. Thanks for reading, you absolutely didn't have to. Hope to see you for the next time.
