Nepal is demonstrating that technology is not just a modern tool but also a protector of nature. The use of drones not only helps protect wildlife but also creates a sustainable conservation model that can be replicated in other countries.

Drones – the "all-seeing eyes" in the jungle skies.
According to Gokarna Jung Thapa, head of technology at WWF Nepal, drones have become an indispensable tool in conservation efforts. Specifically, drones help monitor species such as Bengal tigers, one-horned rhinos, and Asian elephants without disrupting their natural behavior.
With their long-range flight capabilities and thermal cameras, drones can detect unusual activity at night – the time when poaching often occurs. Drones also help capture aerial images, supporting more accurate population counts, especially for species living in hard-to-reach areas.
Additionally, drones are used for early detection of "troublesome" animals such as elephants or rhinos approaching populated areas, thereby warning residents and directing the animals back to the forest.
“Drones help us monitor large areas, save time, and provide visual evidence for law enforcement agencies,” said Gokarna Jung Thapa.

From experimentation to modernization
Nepal began testing drones in 2012 with a device that had a 2-meter wingspan and integrated cameras and GPS.
To date, the technology has been significantly upgraded with high-resolution thermal cameras supporting night vision, precise geo-tagging capabilities, flight times exceeding 1 hour, and monitoring ranges up to 30 km. In particular, vertical take-off and landing (VTOL) capabilities enable drones to operate effectively in rugged mountainous and forested terrain.
These advanced drones are replacing traditional patrol methods such as walking, cycling, motorboats, and even elephants – which are costly and dangerous.

In Bardia, local volunteer groups – especially young people – are trained to use drones to support conservation efforts. They can remotely detect "troublesome" animals, alert residents, and share data with the national park management.
“The drone’s sound is like the buzzing of bees, scaring the wild elephants and causing them to turn around.” – Manju Mahatara, guide and member of the anti-poaching team.
Thanks to conservation efforts, the Bengal tiger population in Nepal has nearly tripled from 2010 to 2022, reaching 355 individuals. The one-horned rhinoceros population also increased from 645 in 2015 to 752 in 2021.
