Elephants roam in about 60% of the land area in Sri Lanka, and in about 70% of that, the rural communities also live and cultivate, creating the perfect grounds for a deadly conflict. A total of 407 elephants and 121 farmers died because of human-elephant conflict in Sri Lanka in 2019 recording the world’s highest death toll due to human-elephant conflict (HEC) in that year. Crop and property damage due to HEC is already overwhelming, and there is no remedy in sight. Electric fencing, elephant raids, and elephant tracking have been exercised for decades now with very limited success. Deforestation, ill-planned development projects, and human encroaching are often blamed as the causes of HEC, however, such causes are irreversible, therefore, it’s time to have a fresh look at the problem and device such solutions that are effective. The way the problem is twined indicates that the key to save elephants is to stop elephants from crop-raiding and killing people in the form of unexpected close encounters. This is only possible if people know at least few minutes in advance the whereabouts of approaching elephants, so that they could team up and deliver a safe response before it is too late. So, is it possible to localize elephants from a distance? Well, the rumbles- the low frequency (14-24Hz) elephant calls might help. Particularly the seismic component of rumbles that propagate long distances through soil could be detected by an array of geophones to triangulate and localize elephants.
