20,000 square meters has been declared mine-free around this village where more than 15 people have been killed or wounded by the explosives, forcing some to abandon their homes and rice fields and seek jobs elsewhere. One villager, Khun Mao, says the rats have been sniffing for suspected mines in a rice field he had been afraid to plant for years. He says, “While it is too soon to say whether the rodents(啮齿动物) can remove every mine. To me, these rats are wonderful.” “The villagers have started to get excited about farming their land again. You can see the light on their faces,” says Paul McCarthy, Cambodia program manager for the Belgian nonprofit organization APOPO.
Two-year-old Victoria proved particularly swift — “very active,” one team member calls her. At another field, Merry and Meynard were completing three hours of effort as a midday sun beat down on the earth. The pair had earlier nosed around on an explosive, stopping moving just above it and scratching the ground — the learned response when a rodent detects TNT(黄色炸药) inside a land mine. Unlike standard mine detectors, the super-sniffers pick up only TNT and not other metal objects. And unlike wage-earning humans, the rats work for peanuts — and their other favorite, bananas. Theap Bunthourn, a member of the 34-member team, tells other advantages of using rats: They are cheaper to acquire and train than mine-sniffing dogs and easier to transport.
