A better way to clear landmines

A few years ago I wrote an article on this blog on Creative methods to clear landmines. It included plants that change color when the roots touch a landmine, rats that can smell landmines, and a gigantic ball that explodes when rolling over a landmine. Neither of these solutions have really solved the problem. With the current clearing speed, it will take more than 1000 years before all landmines have been cleared.
Today, while researching how to calculate the mass moment of inertia, I found a YouTube channel called Physics World. Their latest video is about landmines and a better way to detect them.

According to the video, the problem with landmines is not to find them - the real problem with landmines is to figure out what is a landmine and what is not a landmine that could have been a landmine. What the world needs is a way to detect if what could be a landmine is really a piece of scrap. Because clearing a piece of scrap that you think is a landmine takes as long time as it takes to clear a real landmine. The organization Find a better way aims to find a solution to this new problem.
