Yes, this is close enough. It’s percent of land area used for arable agriculture.
The first map included other types of agriculture (like pasture land). This led to the weird situation where Saudi Arabia was number 1, because apparently they’re classifying 80% of their land as pasture land to the UN. That seemed kind of arbitrary (I know there are rural people there with sheep/goats/cows, but is 80% of the land really being grazed, consistently?), so I switched to this one (arable agriculture is pretty objective - a farm is a farm).
