Bali’s fireflies return with community-based conservation

In Bali, Indonesia, Wayan Wardika launched Bring Back the Light in 2020 after noticing a drastic decline in the local firefly population.
Forty years ago, he remembered seeing large numbers of fireflies, but development, habitat loss, light pollution, and pesticide use have threatened their existence. Wayan and a team of scientists now breed fireflies and release them into the wild, having released nearly 20,000 larva and adults to date. However, Wayan discovered that breeding alone wasn’t enough.
He expanded his initiative to focus on ecosystem regeneration, encouraging local farmers to switch from chemical fertilizers and pesticides to organic alternatives like compost made from cow manure and eco-enzymes created from food waste. He provides these materials to farmers for free and compensates them for any initial losses, aiming to create a sustainable, pesticide-free zone.
Currently, four farmers participate in the program, and Wayan funds the effort through firefly conservation tours and the sale of organic produce from his farm. He believes that improving soil health will benefit both crops and the fireflies, creating a circular ecosystem that supports both human livelihoods and biodiversity for future generations. The project faces the challenge of shifting established farming practices, but Wayan hopes to expand the program to include 35 farmers in the area.
