Mine Detection Rats: The Four-Legged Heroes
Rats are not always seen in their best light, but they play a remarkable role in landmine detection. Yes, you read that right, rats are used for demining! These incredible creatures have the unique ability to detect landmines without risking triggering them, which helps to protect and save countless human lives.
How are these rats trained?
Mine detection rats, also known as HeroRATs, are trained by an organization called APOPO. The rats undergo intense and rigorous training before they can be deployed in the field.
First step: socialization
From a young age, the rats are exposed to various sensory stimuli to acclimate them to the noises, textures, and smells of the environment in which they will work.
Second step: learning signals
The rats are then trained to associate a sound click with a food reward, creating a positive association that will be used to teach them to detect mines.
Third step: target searching
Once this association is well established, the rats are trained to search for targets, in this case, TNT samples, which is the most commonly used explosive in landmines.
Final step: testing
After successfully completing their training, the rats take a final test to ensure they can locate landmines effectively and reliably.
The advantages of mine detection rats
There are many advantages to using rats for mine detection. Here are some of the most significant ones:
- They are lightweight: Due to their light weight, rats do not risk triggering the mines when they walk over them.
- They are efficient: A rat can cover a larger area in less time than a human deminer.
- They have an excellent sense of smell: Rats can detect the presence of TNT even if it is buried underground.
- They are smart and easy to train: Rats are intelligent animals that can be trained to perform complex tasks.
Magawa: an exceptional mine detection rat
Magawa, a giant African pouch rat, received international recognition for his demining efforts in Cambodia. He was trained by APOPO, a Belgian charity, and left an undeniable legacy in his field.
Magawa was robust, weighing 1.2 kg and measuring 70 cm from the tip of his nose to the tip of his tail (this light weight allowed him to walk over mines without risking triggering the detonation). But it was not his size that made him a hero; it was his nose. Magawa was trained to detect TNT, a component commonly used in landmines. His ability to detect mines was unmatched.
During his five-year career, Magawa covered more than 225,000 square meters of land, equivalent to 42 football fields, helping to discover over 100 landmines and other explosives. These efforts helped save countless lives and significantly reduced the risk posed by landmines in Cambodian communities. In total, this mine detection rat helped to restore over 141,000 square meters.
In recognition of his incredible work, Magawa was honored by the People’s Dispensary for Sick Animals (PDSA) in the UK. In September 2020, he received the PDSA Gold Medal, becoming the first rat to receive such an honor.
Magawa’s career highlights the importance and effectiveness of mine detection rats. These remarkable animals continue to save lives and make the world a safer place. Magawa may be a four-legged hero, but he is a true inspiration to us all. Unfortunately, Magawa passed away in 2023, at the age of eight, after a successful career and a well-deserved retirement.
