The map above outlines the borders of Mauritania and Saudi Arabia but is not accurate for size comparison because it's a 2d map with Mercator projection that distorts territories near the poles. The farther a country is from the equator, the more magnified it appears. More about country size projections.

Total agricultural land encompasses all areas used for agriculture: territories under permanent and temporary crops and pastures. It includes land under flowering shrubs, fruit and nut trees, and vineyards, but excludes sites utilized for timber production.
Arable land encompasses fields utilized for temporary crop production, pastures, market or kitchen gardens, and temporarily fallowed land. Land abandoned due to shifting cultivation practices is not included.
Permanent cropland refers to farmland for the long-term cultivation of crops, such as coffee, cocoa, and rubber, which do not require replanting after each harvest. This category encompasses land with permanent crops like flowering shrubs, fruit and nut trees, and vines, but does not include land under trees for timber production.
Inland areas under water, such as large rivers, lakes, and some coastal waterways.
