Of the total area that is used by humans (Agriculture, Urban and Built-up Land),
- urban and built-up land is 1m km²,
- agriculture is 48m km²,
so agriculture is 48 of 49 millions km² used, that’s 98%. The remaining 2% are all streets and housing and other infrastructure together.
It’s close, I worked on a paper pretty much doing exactly this a while back and we had included all of this, metal and oil extraction, all roads, railways, even golf courses on top of your housing. We were at 1.2% of world’s land usage. So I’m sure whatever they got is sensible.
Logging might be missing, but in our data logging was part of forests. So it ties in that regard.
