0:00There are a multitude of videos on
0:02YouTube calculating how much land you
0:04need to be self-sufficient. There are
0:05many people who say that it's simply
0:07one hectare. There are people who say
0:09that with less than five, you can't do
0:10anything. But do you know what I've
0:12seen is missing in those videos? A real
0:14calculation of the calories a person
0:16consumes, broken down by macro and
0:18micronutrients, so that it's not just
0:21survival self-sufficiency, but allows
0:23us to maintain a balanced diet. So I
0:25got to work on it. It took me quite a
0:27long time to do it, to manage to
0:29balance all the foods and
0:31macronutrients necessary for a diet.
0:33But finally, here I bring you the
0:35definitive self-sufficiency video. We
0:37are not only going to calculate these
0:39products that we need, but we are going
0:41to take into account how much land,
0:43which crops, and above all, which
0:45animals. And not only that, but what
0:47feed we need to give those animals that
0:50later will provide food for us.
0:52Everything calculated in a single video
0:54. I put in a lot of hard work. So
0:55before continuing, please, I ask you to
0:58leave a like if you are enjoying the
1:00video. Just minimize it for a moment,
1:02hit the arrow, and with that, I'll feel
1:04happy and content after all the work
1:06I've put in. Let's get started. I've
1:08set this as self-sufficiency for one
1:10person, okay? 2,500 kilocalories. Some
1:12people need more, some people need less
1:15. This is calculated more or less for
1:16me. With this figure, I stay, let's say
1:18, on a normocaloric diet where I
1:20neither gain nor lose weight. And also,
1:22you have to keep in mind that it's
1:23quite a lot of calories, since country
1:25life and self-sufficiency require a
1:27certain amount of physical work, which
1:29means you have to eat more. And as I
1:30told you, I wanted to take it to the
1:32extreme, since we want a balanced diet,
1:35so I have calculated the necessary
1:37grams of protein, fats, and
1:38carbohydrates. We are going to go with
1:41105 g of protein per day, calculated
1:43because I weigh more or less around 70
1:46kg, at more or less 1.5 g of protein
1:48per kilo of body weight. Fats, about
1:51one point something per body weight
1:53would be 75 g, and we fill in the rest
1:55with what I consider the best energy
1:58source, although those on keto will
2:00probably get nervous with this video.
2:02Long live carbohydrates, 350 g per day.
2:06And down here I have broken down all
2:08the foods, always starting from my
2:10personal preferences, both in the food
2:12itself and the animals that I like and
2:14know how to take care of. This may vary
2:16depending on each person, and you also
2:18have to keep in mind that it's
2:19difficult to balance the macronutrients
2:21, because if you add a food with
2:22protein and fat, one goes up and others
2:24go down; in short, I've really racked
2:26my brain over this. Okay, so for daily
2:28consumption, we'd have four eggs from
2:31our hens, 150 ml of milk, which in this
2:33case will be goat's milk, 20 g of
2:35cheese, which we'll also make with our
2:38goats 'milk, and 100 g of meat; in this
2:40case, it will be a mix of the kids the
2:43goats give birth to, as well as some
2:45broiler chickens and our laying hens
2:47when they get older. We have 80 g of
2:50legumes, 500 g of potatoes, and 175 g
2:53of grains. Here we have our two main
2:56sources of carbohydrates along with 600
2:59g of fruit, which will provide all
3:01those essential micronutrients and
3:04vitamins that we can't get elsewhere.
3:07We also have 300 g of vegetables,
3:09adding a bit of fiber to our diet and
3:11bringing in more micronutrients. And
3:13finally, liquid gold: olive oil from
3:15our own olive trees. Here you can see
3:17that I've scaled it up to annual
3:18consumption. I'm not going to read it
3:20all so as not to make it too long. I
3:22simply multiplied this daily amount by
3:24365. What I will mention, because it's
3:28surprising to see everything a human
3:31being has to eat, is that this would be
3:35912,500 calories per year, 38.3 kg of
3:38protein, 27.3 kg of fat, and 127.75 kg
3:41of carbohydrates. As I said, if you
3:43want to know the annual figures, pause
3:45the video and you can read them here.
3:471,460 eggs, 55 L of milk, anyway, here
3:50you have the whole list. I'm going to
3:52erase the board and we're going to
3:54delve deeply into all of this. How can
3:56we actually produce it? How much land
3:58do we need? And as I told you, not just
4:01that, what animals we will need and
4:03what food those animals will also need
4:05to eat so we don't even have to go buy
4:08feed, but rather produce everything at
4:10home. Let's continue calculating the
4:13next steps of this total
4:14self-sufficiency, okay? We're now going
4:17to talk about the animals needed to
4:19reach those production levels.
4:21Specifically, I've added eight laying
4:23hens that will provide us with those
4:25wonderful eggs, and to have a variety
4:27of meat, I've included about 23 broiler
4:29chickens per year. We would also
4:32include, to satisfy our consumption of
4:34both meat and, above all, milk and
4:36cheese, two female goats, and we'd also
4:38have a male so they could produce kids
4:40and so we could also milk them and get
4:43that milk ourselves. Uh, later on,
4:45we'll also move on to calculating what
4:47they eat. And here I have been noting
4:49down the total area of all these crops,
4:52which are the crops dedicated to human
4:54consumption, adding them one by one
4:57until reaching the surface area of
4:592,000 m², okay? 2,000 m² is what we
5:01need for human crops, to which I will
5:03later add the animals. Where do those
5:052,000 m² come from? Well, from the 240
5:09kg of potatoes we need, approximately
5:12350 m². These are approximate figures;
5:14it will depend on each person's land
5:16and what they are better or worse at
5:18growing. Anyway, in the end, this is
5:20all very approximate and a bit based on
5:23my own experience and the calculations
5:25I've made, right? Then we would need 80
5:28kg of cereal for human consumption,
5:31which would require about 400 m², 19
5:34kg of legumes in 300 m², and 140 kg of
5:37vegetables in 150 m² of garden. Then
5:40we would have 270 kilos of fruit, which
5:43would be more or less about 500 m²,
5:46filled with different fruit trees.
5:48Regarding fruit trees, it would be
5:51important—something I always say—
5:53that to avoid having all the fruit
5:55during the same time of year, since
5:57summer or late spring is usually when
5:59most fruit trees start producing, it
6:02would be important to stagger
6:04production, okay? Some, for example,
6:06like strawberries that start producing
6:08early, then perhaps we would move on to
6:10loquats, then we would have apricots,
6:12then apples, pears, grapes, plums, and
6:15all these types of products would
6:16arrive. Then we would also give quite a
6:18lot of importance to pomegranate trees,
6:20which would produce from November and
6:22could last us until January, something
6:23like that. And then we should also
6:25include some citrus crops that would
6:28provide a harvest until those
6:29strawberries come back again. This is
6:32based a bit on my experience and what
6:34grows in my area, but as I tell you, in
6:35other areas perhaps other fruit trees
6:37would be more interesting. And then, to
6:39get 14 liters of olive oil, we would
6:42need about 300 m² more or less of
6:45olive grove. I must also say that this
6:47is calculated to the millimeter for the
6:49figures I gave you before, but you know
6:51how the countryside is, how agriculture
6:53and livestock farming are, and that
6:55sometimes uncertainty is what reigns in
6:57these things. So I would add at least
7:0010%or 20%to the final figure we see,
7:03just in case at some point we have a
7:06pest that causes a smaller harvest. Uh,
7:09if the olive trees don't yield a good
7:11harvest that year, to be safe and
7:13ensure a higher production—and
7:15perhaps even make preserves in case
7:17things go wrong at some point. But
7:20anyway, we'll take that into account at
7:21the end. For now, we have the human
7:23crops and the necessary animals, and
7:25we're going to break down the feed for
7:28those animals to keep adding land to
7:30this figure here. And we continue, as I
7:33mentioned, with the necessary crops for
7:35the goats as well as for those hens and
7:37chickens that will primarily supply our
7:40daily protein, and, well, our daily fat
7:42intake as well. I have to confess
7:44something to you. While I really like
7:46nutrition, and all the previous data,
7:48with a bit of work it wasn't too
7:50difficult for me to figure it out.
7:52Despite having had goats, I am not an
7:54expert in goat nutrition. I haven't
7:56planted grain either, so for all the
7:58figures and types of food you'll see in
8:00this part, I had to rely on information
8:02from the internet; but I think, by eye,
8:04they are quite accurate, although there
8:06can always be a small margin of error
8:08and I like to warn about that. We will
8:11start with the crops for the goats.
8:12Here we have included alfalfa and vetch
8:15. Basically, goats feed on plant matter
8:18, whether fresh or dry, and we would
8:21need about 2,500 kg per year to feed
8:23these three. And this would take up
8:263,000 square meters. It's a huge amount
8:29of space that we will now add up here
8:31to the top area of the total surface. I
8:33should say that if we were to take
8:35these goats out to graze off our own
8:37land, to public land or somewhere like
8:39that, we could save all this amount of
8:41land and thus be self-sufficient with
8:43less. But as I said, in this video I
8:46wanted to propose complete
8:47self-sufficiency without leaving our
8:49plot or our enclosure. We also have a
8:51bit of grain cereal as a supplement,
8:53which would be 200 kg per year, for
8:55which we would need about 600 square
8:57meters of crop. And then, this is
8:59something I only asked artificial
9:01intelligence about regarding the
9:02feeding of these animals. It also
9:04recommended that to have a complete
9:06diet, we should include fava beans,
9:08peas, or some type of legume, about 120
9:10kg per year, which would take us to 500
9:12square meters. In total, you can see
9:15that this adds a good portion of land
9:18to our needs, because in total it would
9:20be 4,100 square meters, and we are
9:22talking about just three animals. As
9:25you can see, I have added it up here at
9:26the top, and later we will get into the
9:28final figure. Here we have the crops
9:30for the hens and the chickens. It is
9:33worth noting that we usually think
9:35directly of grain, but I thought it was
9:37interesting, because in the end I’ve
9:40made layer feed so they lay more eggs
9:42and have a balanced diet, and there are
9:44certain things that, just with grain or
9:47garden waste which would also help us
9:49supplement, uh, the food for both the
9:51goats and the hens, could be missing.
9:54So, to create a balanced diet, in
9:56addition to the grain (which would be
9:59360 kg and we would need about 1,000
10:01m²), we have also added a few fava
10:03beans, peas, and legumes here, which,
10:06since we also grow them for the goats,
10:08we will also give about 120 kg to our
10:11hens and chickens, covering an area of
10:14500 m². We will also plant some
10:17sunflowers to include some fat in our
10:19hens' diet, although, well, we could
10:21perhaps also add olive oil, that could
10:24be a healthy fat for our hens, right?
10:26But in any case, with 30 kg of
10:28sunflower seeds and 300 m², we would
10:30have a completely balanced diet there
10:33that, as I tell you, would be
10:34complemented by garden surpluses and
10:37things like that. For the hens 'feed,
10:39we need a bit less than for the goats,
10:42and that would come out to 100 m². In
10:45total, adding these three things up, we
10:48would be at 7,900 m². And you might
10:51say, "We’re done now, right? We’ve
10:53calculated the square meters we need
10:55for human food and, in turn, for the
10:58food of the animals that are going to
11:00feed us." But of course, we have to
11:02take several things into account, okay?
11:04First, that percentage I mentioned
11:06about the uncertainty of the field, the
11:08weather, a bad harvest, or whatever;
11:11that would be 7,900 m², how much
11:13should we add here? I would say at
11:15least have 10%more crops, more land, in
11:18case something goes wrong. So, I’m
11:21going to crouch down here. That would
11:23be 7,900 plus that 10%, which would be
11:26about 800. Look, let’s go directly to
11:309,000 m², okay? to reduce that margin
11:33of uncertainty. But of course, another
11:35thing is missing here, and that is that
11:36we will have to live somewhere. Also,
11:38perhaps have a shed for implements to
11:40be able to store tools and all sorts of
11:42things to be able to store, for example
11:45, all this alfalfa that we will harvest
11:47, and we will make dry bales out of
11:49some of it to store all this grain. So,
11:52of course, if we add those things, and
11:54add in the aisles so everything isn't
11:57packed together—the orchard with the
11:59olive trees and so on—I think we
12:01should add another 100 m², right? So
12:04we cross out this figure again and
12:07arrive here at 10,500 m². Remember,
12:11this is for a person consuming 2,500
12:14calories. And this seems like a fairly
12:17realistic figure, honestly, because
12:19I've seen many videos claiming that one
12:22hectare could make three people
12:24completely self-sufficient, but if you
12:26have to feed all the animals, I don't
12:28think so. I think you would need quite
12:31a bit more. Also, I wanted to aim for a
12:33balanced diet here. I am a person who,
12:36for example, relies mostly on dairy and
12:39eggs for protein. Hm. And maybe I don't
12:42eat as much meat as other people. I
12:44decided to include a bit more here, but
12:47you could even live with just one of
12:49the two goats to at least have some
12:52milk supply to make cheese and increase
12:55the number of chickens. For someone
12:57more carnivorous or who prefers goat
12:59meat, you could eliminate a few
13:01chickens and add more goats. In other
13:03words, the combinations are endless and
13:05ultimately it depends on everyone's
13:07personal tastes. But I think it’s
13:09been a fairly complete analysis; with
13:12these 10,500 m², we don't just meet
13:14our necessary calories, but we would
13:17have a completely balanced diet and a
13:19realistic estimate of how complicated
13:22it really is to be self-sufficient,
13:24right? Then, in the real world, in
13:27everyday life, we probably wouldn't
13:30care to have so much land for our goats
13:32or so much land to plant cereal for our
13:35chickens, and it would simply be easier
13:37to go to any store to buy it and save
13:40the trouble. In that case, if we
13:42consider self-sufficiency simply as the
13:45space needed to grow our own food while
13:47buying animal feed, you can see that we
13:50would end up with a much smaller figure
13:53of about 2,000 m². Which, added to
13:56that uncertainty margin and the land
13:58for the house, the barn, and so on,
14:01might bring us to about 3,500 or 4,000
14:04m². In that case, I would say that one
14:06hectare is enough for the whole family.
14:08What did you think of this calculation?
14:10Do you see these as correct estimates?
14:12Would you have added more of one thing
14:14and more of another? It pained me to
14:17leave out nuts, which are also a fairly
14:19productive crop, like planting a few
14:22almond trees and such. The thing is,
14:24because they contain so much fat, when
14:26I tried to balance the protein, the fat
14:28count went way up, but it could still
14:30be an interesting crop that might allow
14:32us to have fewer animals or less of
14:34other things. Anyway, I think this
14:37turned out to be a pretty interesting
14:39guide and we’ve reached a fairly
14:40approximate figure. I’ll repeat that
14:42if you liked the video, hit the like
14:44button, and especially check that
14:45you're following me, because many of
14:47you watching my videos don't know it
14:49because the algorithm recommends them,
14:50but you aren't even following me. So if
14:52you liked the video, hit the little
14:54button, the bell, and all those things
14:56we YouTubers always talk about. And
14:58that’s all, I’ll say goodbye for
14:59now. Thank you so much as always for
15:00watching, and I’ll see you in the
15:02next one.
