HWANGE, Zimbabwe — When GPS-triggered alerts show an elephant herd heading toward villages near Zimbabwe's Hwange National Park, Capon Sibanda springs into action. He posts warnings in WhatsApp groups before speeding off on his bicycle to inform nearby residents without phones or network access.
The new system of tracking elephants wearing GPS collars was launched last year by the Zimbabwe Parks and Wildlife Management Authority and the International Fund for Animal Welfare. It aims to prevent dangerous encounters between people and elephants, which are more frequent as climate change worsens competition for food and water.
''When we started it was more of a challenge, but it's becoming phenomenal,'' said Sibanda, 29, one of the local volunteers trained to be community guardians.
For generations, villagers banged pots, shouted or burned dung to drive away elephants. But worsening droughts and shrinking resources have pushed the animals to raid villages more often, destroying crops and infrastructure and sometimes injuring or killing people.
Zimbabwe's elephant population is estimated at around 100,000, nearly double the land's capacity. The country hasn't culled elephants in close to four decades. That's because of pressure from wildlife conservation activists, and because the process is expensive, according to parks spokesman Tinashe Farawo.
Conflicts between humans and wildlife such as elephants, lions and hyenas killed 18 people across the southern African country between January and April this year, forcing park authorities to kill 158 ''trouble'' animals during that period.
''Droughts are getting worse. The elephants devour the little that we harvest,'' said Senzeni Sibanda, a local councilor and farmer, tending her tomato crop with cow dung manure in a community garden that also supports a school feeding program.
Technology now supports the traditional tactics. Through the EarthRanger platform introduced by IFAW, authorities track collared elephants in real time. Maps show their proximity to the buffer zone — delineated on digital maps, not by fences — that separate the park and hunting concessions from community land.
