In this guide, we're going to talk about why food self sufficiency is 100% possible for you, even if you don't have much land.

The commonly held belief is that you need at least one acre to become fully self sufficient. That may be true if you're planning to grow all of your own food.
But, what if the idea of self sufficiency was flipped on its head so that becoming self sufficient was not just about how much food you grow on your own land, but about how much food you can forage, hunt or store independent of external inputs in the event of an emergency?
If you start to view self sufficiency from this viewpoint, you will soon realise that the amount of land you own does not necessarily mean you can't be self sufficient. It does, however, mean you need to be extraordinarily good at planning what you need to survive in the event you can't get access to the things that you need through the usual channels.
This is exactly what the bournebright method of self sufficiency is all about. It's about taking the things you have, in the situation you exist within, to create the future you want. This extends outward to all the seven elements of self sufficiency including food, shelter, income, energy, health, wealth and people.
In this guide, we’re specifically going to look at how you can achieve 100% food self sufficiency without much land.
What is food self sufficiency?
The ideal scenario is that you can grow all of your own food on your own land to sustain yourself and your family independent of the state or the supermarkets.
At first glance, it sounds impossible for most people. However, if we unpack that statement, what we are actually saying is that we want to be able to survive and feed our families without having to shop at the main supermarkets or use any income from the state to purchase the things we need to survive.
This leaves us with a few options:
- Grow enough food on our own land to sustain our family.
- Forage for food in the area around us.
- Hunt or fish for food.
- Purchase our food directly from the people who DO grow it.
- Buy in bulk now and store for use later.
As you can see, growing your own is not the only path to food self sufficiency.
In any event, understanding how much food you need to be self sufficient is absolutely key.

How much food do you need to be self sufficient?
Before you can figure out how you are going to become self sufficient in food, you are going to have to calculate how much food you need.
Modern dietary advice suggests that an adult male needs at least 2200 calories per day to survive, with around 2000 calories for adult females.
These numbers are indicated to ‘maintain a healthy diet,’ they aren't necessarily specific to the minimum a person might need just for basic survival.
When you start to look at the minimum daily calorie requirement to survive; the human body needs around 1000 to 1500 calories per day to stop the body from entering starvation mode.
When your body enters starvation mode it will use muscle mass and fat as a source of energy to keep your basic functions working.
If you maintain a diet with a calorie intake of under 1000 calories per day for a prolonged period, whilst also continuing to carry out physical daily activity, you can expect your body to become nutritionally deficient.
Nutritional deficiency will lead to decreasing muscle mass, slow or sluggish energy levels, unpredictable moods, depression and eventually starvation (where your body will begin to shut down its organs).
How many calories do you need to survive per day?
In order to remain functional, your basic daily calorie intake must be at least 1000 calories per day.
If you are thinking about food self sufficiency for yourself, it's an easy calculation. But, if you are part of a family, remember that each person in the family will need at least 1000 calories per day.
Now that you know how many calories you need to take in on a daily basis just for basic survival, it's time to look at where you can get those calories from.
In the tables below, I've used data from over at Calories.info to compile several lists of foods with their calorific values.
- Top 50 Foods With The Highest Calorific Value
- Calories In Vegetables
- Calories In Fruits
- Calories In Meat
- Calories In Nuts
- Calories In Beans & Legumes
- Calories In Fish
Using this information, you can work your way backwards from the numbers to figure out what you and your family will need on a daily basis.
With this knowledge you can then work out exactly what you're capable of growing in your current location and create a plan to make up any shortfall (forage, hunt or buy) for the rest.

Now that you know how many calories are in different types of foods, you can start to apply that to your own situation and work out how much of it you can grow yourself and how much of it you're going to need to supplement from other sources.
Food Self Sufficiency: A Working Example
To make this contextual, let's run through a working example assuming a family of four.
For basic survival we know that the family is going to need 4000 calories per day, 1000 calories for each person.
If we start with what we can grow in our own garden, say, for example, we have enough space to grow 30 bags of potatoes. We know if we look after the bags of potatoes, we are going to get about 10 pounds of potatoes from each bag; that's approx. 25 potatoes at an average weight of about 150g each.
We can see from this simple example that we are still 850g short in calories to meet our basic survival needs.
If we have no more space left in our garden then we know we need to make up the shortfall by buying supplemental food and storing it, foraging or hunting.
Foraging and hunting are separate skill sets in their own right and will be covered in their own guides so for now, let's just get you up and running as quickly as possible with the buy and store method.
Jacket Potato & Beans Will Keep You Alive
Using our tables to find navy beans in tomato sauce (the kind you buy from the supermarket) we can see that a typical tin of 415g will provide about 300 calories per 100g.
Thus, if we supplement our single potato with a full tin of beans, we will actually meet our minimum daily requirement for food self sufficiency – survival.
What I'm saying then, is a jacket potato and beans will keep you alive.
In practical terms, this means you need one baking potato and a tin of beans for every person in your family for every day you want to keep them from starving.
So, for a three month supply of food, you're going to need 90 tins of beans and 90 potatoes per person. This would be a great time to learn how you can buy and store potatoes for months after you buy them. Whilst not permanently self sufficient, this does meet the goal of not needing to use the existing infrastructure for 3 months in an emergency.
Of course, this is a very simple example of how you can apply the information in this guide to work out how much food you need to grow and how much food you need to supplement in your quest for food self sufficiency.
I'm not for one second suggesting that you can actually live on jacket potato and beans for the rest of your life, I'm just using this as an example to show you the bare minimum of what is required, but also to show you that the bournebright idea of food self sufficiency is achievable for anyone.
This is the baseline. You now need to learn how to forage, hunt and grow more as you continue your journey towards food self sufficiency.
