An Accidental Refuge
The Sri Lankan Civil War, which lasted from 1983 to 2009, had an unintentional ecological consequence. As people fled their homes and abandoned farms in the northern and eastern parts of the country, these areas became depopulated. With human activity drastically reduced, a de facto refuge for wildlife emerged. Sri Lankan elephants (Elephas maximus maximus), the largest subspecies of Asian elephant, began to move into and utilize these former human landscapes. The abandoned agricultural fields provided a ready food source, and the absence of people removed a major threat.
This process demonstrated how quickly large and intelligent animals adapt and expand their territory when human pressure is removed. The conflict zones, dangerous for people, became areas where elephant populations could stabilize and even grow. However, this period of quiet coexistence was temporary. When the war ended in 2009, the conditions were ready for a new kind of conflict.
A Post-War Collision
The end of the civil war allowed displaced communities to return to their ancestral lands. They arrived to find a changed landscape, one now occupied by elephants who had come to see the area as part of their home range. The result was a dramatic and immediate spike in Human-Elephant Conflict (HEC). Sri Lanka now has one of the highest rates of such conflict in the world, with hundreds of elephants and dozens of people killed annually. In 2023, a record 470 elephants and 176 people were killed in these encounters.
The elephants, particularly solitary adult males, venture into villages and farms at night in search of food, raiding crops and sometimes destroying homes. Researchers using GPS collars found that more than 70% of Sri Lanka's elephants live outside of officially protected areas, sharing landscapes directly with people. The conflict is caused by habitat loss and the collision of two populations—human and elephant—reclaiming the same space simultaneously. Farmers, facing major economic losses, have resorted to using illegal electric fences, firearms, and explosive bait known as "jaw bombs" to protect their livelihoods, leading to slow, painful deaths for the elephants. This intense post-war conflict provides a clear example of how wildlife reclamation of an area can lead to severe challenges when humans return.
