A Belgian de-mining organisation has
managed to clear more than 130 000 square kilometres of
landmine-infested areas in the Mozambican southern province of Gaza
with the help of giant pouched rats.
The intelligent rodents are too light to detonate the mines they find by sniffing, so they are not disposable.
Their trainers at Sokoine University of Agriculture in Tanzania say that for the reward of a bit of banana the rats can do a much better job than dogs.
