Thank you for the answers guys. I love lists lol, so I went first to the "List of..." link. I was astounded by them saying that Brasil has only 6.93% of arable land. So I looked what arable land means, and learned that the "able" in the expression is fallacious. It is land actually being used, not potential land. As per the FAO definition: "Arable land includes land defined by the FAO as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land temporarily fallow. Land abandoned as a result of shifting cultivation is excluded". Phew!

I have not checked the other links yet, but will soon and give feedback.

Thanks again,
