Generally, there are no exact maps or land registers of mine fields so that the approximate scope of the contamination with mines can only be estimated. One differentiates between four types of contamination: very heavy (surfaces > 100km2), heavy (surfaces 99km2 - 20km2), medium (surfaces 19km2 - 5km2) and light (surfaces < 5km2).
Example of how to read the map:
In 2017, Sudan was heavily contaminated with landmines.
