As a follow up to an earlier blog post addressing an article in the Phnom Penh Post claiming that the Kingdom’s arable land is “all but gone”, I thought I’d delve into this issue a little further and look beyond some of the obviously inaccurate numbers quoted in the article. Based on data obtained from Open Development Cambodia and other sources, I’ve put together this map, which gives a more comprehensive picture of land use and land use potential.
