Iceland seems the country with the smallest quantity of primary crops per square metre: 7 grams per year. Who wants more vegetal food for themselves and for their cattle, lives anywhere else; almost everybody does. The global average production seems to be around 900 grams.
The global production of primary crop commodities reached 9.5 billion tonnes in 2021: 1,200 kg per person. Cereals were the leading group of crops, representing 32% (3 Gt), followed by sugar crops (22%: 2 Gt), vegetables and oil crops (12% or 1.14 Gt each), fruit (10%), and roots and tubers (9%: 0.85 Gt).
I think one can live on less than 3.28 kg of primary crops per day. We can estimate what amount of plants needs to be harvested for several diets.
It seems we use 40 million km2 for animal husbandry and 11 million km2 for crops. Crops provide 82% of our calories and 63% of our proteins. Could we get all our proteins from 14 million km2 of farmland? How much land do we need for healthy diets? If we’re wasting a third of our food, were 10 million km2 enough?
We’re degrading (gradually losing) soil through overgrazing (34.5%), deforestation (29.5%), and the mismanagement of arable land. We can help reduce grazing and deforestation, and improve land management.
Any increase in the area used for agriculture costs a lot. The number of square metres of agricultural land per person dropped 56% from 14,500 to 6,300 between 1961 and 2018. It seems useful to avoid reducing this average area.
The worst ecological densities of people (the product of their density and of their ecological footprint) are on the luxury islands of Singapore and Bahrain. Israel ranks 9th with the index of 1245; Palestine: 351. Global average: 400; it seems that 200 people live in an area of 1 square kilometre as if 2 square kilometres were available.
It seems that only 104 million square kilometres are habitable: 12,876 square metres per person; a raw density of 77 people per 1,000,000 square metres.
There are some 5,000 square metres of forest per person. It seems that we haven’t used all forest land and that we are using some of it indirectly.
These things can mean that a human being could use between 11,000 and 12,000 square metres of land, or at least one hectare, for everything: housing, food, clothing, energy, etc.
What resources do you want to use?
How much land are you going to use? We can help you use it efficiently.
