Technology helps reduce human-lion conflict
Kenyan wildlife authorities have attached special tracking collars to lions that have been known to attack livestock.
The 10 offending animals were fitted with Global Positioning System (GPS) collars that alert rangers as soon as the lions leave Nairobi National Park on the outskirts of the capital.
Rangers from the Kenya Wildlife Service (KWS) use the coordinates sent by the collars to their mobile phones to track the wandering lions and return the wild animals to the 12,000-hectare park.
When the lions venture near the city and kill livestock they are often hunted down by farmers, particularly Maasai herdsmen, and killed in revenge for the loss of the farmers' animals.
In recent years Nairobi's rising population has seen the city consume more and more of the surrounding countryside, resulting in increasing clashes between humans and wildlife.
