Can Lemongrass Help Reduce Human-Elephant Conflict in Sri Lanka?

So-called human-elephant conflict has been a recurring issue in Sri Lanka for years. With no viable and permanent solution, different organizations and groups come up with their own plan and methods of dealing with this dilemma. Some, of course, favor humanity at the cost of the wildlife.

With farmers constantly suffering from crop raids and elephants being subjected to agonizing forms of repellents, Trunks & Leaves dedicated our energy and resources to finding a suitable solution to this issue.

This project has been set back due to the pandemic but is still ongoing. But we are now exploring ways to develop alternate sources of income for farmers who lose crops to elephants.

The climate and landscape of the Udawalawe region are fertile for plants like lemongrass, and the value of this plant has increased due to the commercial importance of aromatic oil.
