The animal trainers ‘found that a kind of rats from Africa were clever and had.a sharp* sense of smell. The rats were about 75 cm long and.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.
In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana. The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu. “You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals.”
After nine months’ training, the rats were taken to a minefiel山 They’ran across the minefield, stopped, sat and scratched the ground to tell the deminers* that they smelt out’a mine. Then the mine was cleared. It had taken two ‘deminers a day to clear a 200㎡ . minefield, but with the help of two rats ‘they could finish it in two hours.
The rats and ~he deminers saved thousands of lives, “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.
