A community near the famed Serengeti National Park in Tanzania is enlisting the help of bees to reduce escalating tensions with elephants that enrage locals by trampling upon their crops.
A fence made of beehives is being constructed around a 0.4 hectare farm close to the Ngorongoro conservation area as part of the pilot project to see if the buzzing bees deter elephants that stroll on to cropland.
It is hoped that the “bee fence” concept, which has already been deployed in Kenya and Botswana, can help reduce conflict in northern Tanzania, which has become a hotspot for clashes between humans and elephants.
As habitat is converted into farmland by people, elephants are increasingly wandering on to farmed land, either to munch on crops or simply because their traditional migratory routes passed through the area. People who attempt to scare elephants off with firecrackers or gunshots into the air can provoke an aggressive reaction from startled elephants, leading to deaths on both sides.
Conservationists have searched for non-violent remedies to such conflicts, which also exist in India and Sri Lanka, such as planting chilli near crops or using drones to scare elephants away.
However, the bee fence could be the most promising idea of all with a coalition of groups looking to roll out the concept in the tourist haven of northern Tanzania, which includes the Serengeti, site of the famous 1.5 million-strong wildebeest annual migration and the spectacular Ngorongoro crater, which teems with wildlife including the “big five” — lions, leopards, elephants, rhinos and buffaloes.
A farm near these neighboring World Heritage sites is to be surrounded by a wire strung between tall wooden polls. Beehives are to be hung on the wires, with the bees alerted to the presence of elephants when the wires are disturbed.
The idea was conceived by zoologist Lucy King, who was brought up in east Africa, with the Tanzanian pilot funded via a US$6,000 grant from the Ian Somerhalder Foundation.
“Once the bees vocalize, the elephants will be alerted and run away,” said Hayley Adams, a US veterinarian who is working on the project. “Elephants are highly cognitive so if they have been stung before, you’ll see an extreme reaction to the sound of bees. It’s a cliche, but elephants have good memories. Some of the younger elephants don’t realize and get stung on their ears, which are very sensitive, so they remember to not go near there again.”
Adams said the year-long trial, if successful, could be expanded across the region and prove beneficial to the local community by reducing altercations with elephants while supplying people with honey for consumption or sale.
“This is far better than firing in the air or using sticks to hit elephants, which just makes them aggressive,” she said. “We need an holistic approach that benefits both people and elephants.”
Adams’ non-profit group, the Silent Heroes, which supports wildlife conservation in 13 nations, is also to be involved in the launch of Tanzania’s first elephant orphanage, which is set to open this month.
The Ivory Orphans Project, located near the Tanzanian town of Arusha, expects to be able to care for up to 40 young elephants slaughtered by the worsening poaching crisis in Africa.
About 30,000 African elephants are slaughtered each year by poachers for their ivory. In Tanzania, elephants are being lost at a rate of about 60 a day.
“There are a lot of gaps in the system in looking after orphaned elephants,” Adams said. “I’ve seen a lot of orphans suffer a lot of behavioral issues, there are a lot of parallels with veterans suffering post traumatic stress disorder. We need to step up the care, not just medically, but socially and emotionally as well.”
OFF BORDER ISLAND: The fisheries official disappeared from a patrol vessel wearing a life jacket and leaving behind his shoes, indicating an intentional move, Seoul said North Korean soldiers shot dead a suspected South Korean defector at sea and burned his body as a COVID-19 precaution after he was interrogated in the water over several hours, Seoul military officials said yesterday. It is the first killing of a South Korean citizen by North Korean forces for a decade, and comes with Pyongyang at high alert over the COVID-19 pandemic and inter-Korean relations at a standstill. The fisheries official disappeared from a patrol vessel near the western border island of Yeonpyeong on Monday, the official said. More than 24 hours later, North Korean forces located him in their waters and
ACADEMIC FREEDOM: One professor told her students to submit anonymized papers and not to record any online classes. Some US schools have announced similar steps Students at Oxford University specializing in the study of China are being asked to submit some papers anonymously to protect them from the possibility of retribution under the sweeping new security law introduced three months ago in Hong Kong. The anonymity ruling is to be applied in classes, and group tutorials are to be replaced by one-to-ones. Students are also to be warned that it will be viewed as a disciplinary offence if they tape classes or share them with outside groups. The Hong Kong National Security Law was imposed on June 30 by Beijing after more than a year of pro-democracy
Japan’s government yesterday urged people to seek help if they were struggling to cope, following Sunday’s death of the popular actress and Miss Sherlock star Yuko Takeuchi, 40. News of her death shocked the nation and follows other recent cases of Japanese celebrities taking their lives, with figures showing a recent rise in suicides. Takeuchi was a household name in Japan and had given birth to her second child in January. Japanese Chief Cabinet Secretary Katsunobu Kato did not mention a particular case, but said that some people were struggling to cope during the COVID-19 pandemic. “There has been an uptick in the number
China on Thursday lashed out at the US at a high-level UN meeting over its criticism on the COVID-19 pandemic, with its envoy declaring, “Enough is enough.” Two days after US President Donald Trump used his annual address to the General Assembly to attack China’s record, US Ambassador to the UN Kelly Craft, also took an outraged tone — after which her Chinese counterpart showed palpable anger. “I must say, enough is enough. You have created enough troubles for the world already,” Chinese Ambassador to the UN Zhang Jun (張軍) told a Security Council meeting on global governance attended through videoconference
