Magawa has cleared more than 141,000 square meters of land, the equivalent of some 20 soccer fields, sniffing out 71 land mines and 38 items of unexploded ordnance, according to Apopo.
While many rodents can be trained to detect scents and will work at repetitive tasks for food rewards, Apopo decided African giant pouched rats were best suited to land mine clearance because their size allows them to walk across mine fields without triggering the explosives — and do it much more quickly than people. They also live up to eight years.
Magawa is part of a cohort of rats bred for this purpose. He was born in Tanzania in 2014, and in 2016, moved to Cambodia's northwestern city of Siem Reap, home of the famed Angkor temples, to begin his bomb-sniffing career.
In retirement, Magawa will live in his same cage as before and follow the same daily routine, but won't be going out to the minefields any more, said Lily Shallom, an Apopo spokeswoman, contacted by phone at the organisation's operational headquarters in Tanzania.
He'll be fed the same food, have playtime every day and get regular exercise and health checks. He eats mostly fresh fruit and vegetables, said Shallom, supplemented with small sun-dried fish for protein and imported pellets for vitamins and fibre. For 20 to 30 minutes a day, he is released into a larger cage with facilities such as a sandbox and a running wheel.
Apopo also works with programmes in Angola, Zimbabwe and Mozambique to clear millions of mines left behind from wars and conflicts.
More than 60 million people in 59 countries continue to be threatened by land mines and unexploded ordinance.
In 2018, landmines and other remnants of war killed or injured 6897 people, the group said.
