Edit:
This is not intended as "how to grow all your food you ever need at home".
It merely provides the vegetables.
You still have to get your grains (and therefore the majority of your calories) from somewhere else.

That is not enough food to sustain a person, but a great way to cut down on grocery needs!
Is it efficient land use, though?
Keep in mind, we have to be able to feed 10 billion people. Homesteads like this are of course better than just plain grass, but compared to a farm, the output per area is probably really low. So there's still land being "wasted".
