A lot of the people who live there grow a lot of their own food. It is harvested and then eaten, without ever having been bought or sold, so it never shows up in GDP or suchlike figures.
Labour-wise this is not a very efficient process, but if your limiting factor is land are, it suddenly looks like a lot more of a goer.
Yes I'm aware of that, but with American Family owned farms producing that large a percentage of the worlds food this "Evil corporate big AG" mantra is quite exaggerated.
What parts of that report I have had time to read are often contradictory to other parts. In one place they state a goal of reducing the number of animals raised on farms. OK if you don't mind eating chicken feed instead of chicken mind you but in another they talk of adding manure to improve the soil. now if you get rid of the animals where is your manure coming from? In yet another place they are promoting close grazing a plot of land just prior to 'no till' planting a grain crop on it and counting the value of the feed grazed off in their profit accounting. Nothing wrong with that but again with what animals and where did they graze while the crop was growing?
Things like deep double digging sound great but really are no different then deep subsoil plowing done by tractor only much slower and more expensively done. Anything a man with shovel and hoe can do to the soil a tractor with the right implement can do as well and cheaper. Anything you want to add to the soil can be added by machine.
They pretend that modern mechanized farming does not already make use of available organic biomass as fertilizer and soil amendment when in fact farmers use all they can get. The same with erosion control and water management. Sure you can do it better then people that have been doing it for decades. NOT!
Did your report account for the vast numbers of people who grow and live on rice, sorghum, millet, manioc and other non grain products? Or they would do if the US and EU weren't dumping subsidised food into their countries and putting their farmers out of business. If US and EU farming is so efficient why are huge subsidies pumped into the agriculture of those nations?
Although it is not quite as efficient as using manure you can grow food using green manures so animals aren't essential and artificial fertilisers are even less efficient than green manures.
Mechanised farming is only cheaper if you have high wage levels and cheap tractors and fuel. If you can't afford a tractor, let alone the fuel to run it, it is not cheaper. Industrialised farming is the most efficient way of turning oil into food while gardening, which is what the majority of the world's farmers do, is the most efficient way of producing food from a given area of land. The output is about twice that of an industrialised farm.
Meanwhile
this report says that industrialised farming has reached peak output and
this one from the UN confirms that small scale organic farming is the way to feed the world.
It has been proved in the UK that one person can get all their vegetable requirements off a 3 metre by 3 metre plot (10 ft x 10 ft). No, that doesn't give you your protein or calories but the area to provide vegetable protein on top of that would be very much larger. The calories would depend on how you provided them and animal protein would need a fair bit more: up to ten times more for cattle, three times more for poultry and pigs and something in between for sheep.
