We’ve heard from a few people this month who saw a story in the news about Cambodia unveiling a stone statue of Magawa – the world’s most successful landmine detection rat.

So now seems like a good time to share about the the African Giant Pouched Rats who are considered heroes for contributions to landmine detection in Cambodia. They are a major part of why Prey Veng was declared landmine free in 2022.

Known for their incredible sense of smell, the Tanzanian social enterprise APOPO trains these rats to detect explosives (in some contexts they are instead trained to detect tuberculous). The rats are much lighter than most canines and are too light to set off landmines. They are also more “discrete” in detecting explosives in contexts with heavy metal contamination and, being native to a tropical environment, perform well in high heat and humidity. The rats also much faster at detecting landmines than electronic sensors.

A rat can search an area roughly the size of a tennis court in about 30 minutes. A human deminer using traditional tools might take several days to clear the same space.

The rats work systematically, guided by handlers who care deeply for their well-being. They are trained using positive reinforcement, receiving food rewards for every successful detection. When they’re not working, the rats live comfortable lives with playtime, rest, and regular veterinary care.

If you are ever in Siem Reap (location of Angkor Wat) we would highly recommend visiting the APOPO to learn more. On our end, we will definitely look for the new statue next time we’re there.
