Genuine question, why is it very difficult even with our 21st century technology to accurately detect landmines for the purpose of destroying them after the war?

In order to be effective landmines need to be very close to the land surface thus should be easier enough to detect. Researcher in Japan has succesfully detect using low power radar sub-surface bamboo shoots since they are more expensive than bamboo shoots that are already grown over land surface.

For safe and fast detection mechanism close to the ground aerial UAV can be deploy to scan the the suspected land mine area.

Something is missing and don't add up here, perhaps someone can help explain the situations?
