In a village in central Nepal, growing conflict between farmers and rhesus macaques has prompted researchers to test artificial intelligence-based systems that can swiftly detect and deter the monkeys, reports contributor Praveen Kumar Yadav for Mongabay. A 2026 study that followed rhesus macaques (Macaca mulatta) in one central Nepal region, found that nearly half of their diet consists of cultivated crops. In villages like Birta Deurali, also in central Nepal, farmers take turns guarding fields every two hours, Yadav reported. To alleviate this burden, researchers in the country are developing AI-driven solutions. Progress Jung Thapa, a researcher at Madan Bhandari University of Science and Technology, has developed a system built on cameras and lightweight computing devices trained on more than 4,000 annotated images. It detects monkeys and interprets their behavior, such as whether the monkeys are moving, feeding, or being vigilant, with an 88% accuracy across 28 field trials. “If a monkey is still watching, the farmer has time,” Thapa said. “If it is already feeding, the response has to be immediate. A machine can detect. But a human decides.” Once a threat is identified, the system sends an alert straight to the farmer’s phone. Meanwhile, Santosh Giri, an assistant professor at Tribhuvan University, is developing a prototype that pairs AI detection with an ultrasonic deterrent to repel monkeys. The deterrent system is, however, yet to be tested in working farm environments. Both Thapa and Giri acknowledged that translating these technologies to field conditions is challenging.
