More than boots and bullets: This app could help turn the tide on poaching

The newest weapon in the fight against wildlife poaching and illegal logging doesn't rely solely on boots or bullets, but on a computer software application driven by artificial intelligence. Called Protection Assistant for Wildlife Security, or PAWS, the app uses algorithms – similar to the mathematical models used to power computer games – to devise strategies for defeating those who seek to destroy nature. Thousands of animals are illegally slaughtered each year for their ivory, skin and bones for use in traditional medicines and feeding black market demand, while others meet their death at the hands of illicit trophy hunters, in what the World Wildlife Fund refers to as "a global poaching crisis." Last year alone, around 30,000 elephants and a record 1,338 rhinos were killed in Africa, while tens of thousands of other animals were poached and trafficked, "feeding an illegal wildlife trade that is increasingly being driven by international organized crime," the international conservation group said in a recent statement. Developed in 2013 and still in the test phase, the PAWS software analyzes data on terrain, topography, routes most frequently used by animals and paths traveled by poachers, said Milind Tambe, a computer scientist and professor of industrial systems engineering at USC who developed the technology with his doctoral students, including Fei Fang and Thanh Nguyen.
