When dawn rose one chilly morning last July in Kitengela, a dusty savannah on the outskirts of Nairobi, Kenya, six lions lay dead in the dim headlights of an old land cruiser. Just hours earlier, dozens of Maasai men had descended upon them with sharpened spears in a fit of anger and frustration.
“We killed them because we had no other option,” claimed Charity Mutunkei, whose four goats had been killed by the lions. “The lions come again and again.”
Over the past several years, residents of the Kitengela plains have had an enormous problem. The area lies on the edge of popular tourist destination Nairobi National Park, a beautiful game park just 7 kilometres (4.6 miles) from Nairobi’s City Centre, brimming with lions, rhinos, giraffes, cheetahs, and other wildlife. While the park is secured by an electric fence on three sides – those that border the city – the open end allows wildlife to spill out into Kintengela, once a vast wildlife corridor that is now quickly becoming filled with housing estates. Lions have been straying outside the park at night and snacking on their form of convenience food – local residents’ cattle, goat, and other animals.
For many of the residents, livestock is their only livelihood, and they will go to any lengths to protect them – including poisoning or killing the hungry beasts. As a result of conflicts like this, Kenya has been losing on average 100 lions a year, and there are now just 2,000 remaining in the country.
Richard Turere, a Maasai who lives not far from Kitengela, is scared of the lions – and for good reason. He’s only 13, and small for his age – no match for a hungry feline on the prowl. But that didn’t stop him at the age of 11 from wanting to find a way of protecting his family’s livestock.
With absolutely no mechanical or technical training - aside from having the best marks in his science and maths class – Richard cleverly invented a completely hacked yet remarkably effective system to keep the lions away, with little idea that it would eventually allow him to share the stage at TED2013 alongside the likes of Sergey Brin, Peter Gabriel and Elon Musk. When asked about his favourite part of the conference, he immediately remarked “petting the sharks at the aquarium,” then, after a pause, “oh, and seeing Bono!”
Richard’s device costs less then ten dollars, is made from nothing more than basically spare parts, and works because of one simple yet astute observation: he noticed that lions would stay away when he walked around with a flashlight.
The system, called “Lion Lights” is about as basic as you can get, constructed from LED bulbs from broken flashlights, an old car battery, a solar panel, and a motorcycle turning light indicator box. By rigging the LED bulbs to the motorcycle indicator box, powered by the battery and solar panel, Richard was able to give the lights their distinctive flashing effect.
According to Dr Charles Musyoki, a senior scientist in carnivore issues for Kenya Wildlife Service, the flickering lights is an ingenious applied design intervention that introduces a “serious risk consideration” for the lions. While a steady light will not scare lions, flickering lights from multiple sources confuses them, and indicates the presence of something larger than them, making it a risk “not worth taking”.
Musyoki says that although Lion Lights may seem simple, “no one else in Kenya had imagined putting the lights in this context.” They have also reduced tension between the Kenya Wildlife Service and local communities, by reducing the number of attacks on livestock in areas with the lights, he says.
