Singapore’s position as an air cargo hub makes it a critical transit point in the illegal rhino horn trade from South Africa to Southeast Asia.
When Singapore customs officers investigated a suspicious shipment of furniture fittings at Changi Airport last month, a pungent smell led them to something far more sinister.
Inside the cargo from South Africa were 20 rhino horns weighing 35.7kg and worth around S$1.13 million (US$870,000), along with 150kg of other animal parts including bones, teeth and claws.
The Nov 8 seizure marked Singapore’s largest rhino horn haul to date, surpassing a 34.7kg cache intercepted in 2022. Both shipments followed the same 9,000km route from South Africa to Laos, a known destination for trafficked wildlife products.
Wildlife experts say Singapore has become a transit hub in a smuggling pipeline that begins in South Africa’s rhinoceros-rich grasslands and terminates in Asian markets where the horns – despite being composed simply of keratin, like human fingernails – command high prices as supposed medicine and status symbols.
The trading of rhino horns is prohibited under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which lists all rhino species as endangered or critically endangered.
THE AFRICAN SOURCE
South Africa dominates global rhino horn seizures for one simple reason: it’s home to most of the world’s remaining rhinos.
The country has around 12,000 white rhinos – 76 per cent of the global population – and 2,300 black rhinos, representing 34 per cent of that species, according to WWF South Africa’s rhino conservation manager Jeff Cooke.
“In essence, there are more populations of animals to poach, or it’s easier to find poachable herds in South Africa than in other parts of the world,” said Professor James Larkin, director of the radiation and health physics unit at the University of the Witwatersrand in Johannesburg.
Poaching is concentrated in areas with the densest rhino populations, such as the Greater Kruger National Park and Hluhluwe-Imfolozi Park in KwaZulu-Natal province, Mr Cooke said.
MAFIA-STYLE SYNDICATES
The fight against rhino poaching has become what Prof Larkin calls an “ongoing arms race” between increasingly sophisticated networks and conservation authorities.
Modern poaching operations function as “highly organised, syndicated crime”, Mr Cooke said, with networks constantly adapting to exploit weaknesses in security measures.
A typical poaching gang consists of three people – a shooter, an axeman to remove the horn and a logistics coordinator – who may spend up to three weeks living in the bush, tracking rhinos while evading anti-poaching patrols, said Prof Larkin.
These teams use helicopters, dart guns, snares, silenced high-powered rifles, night vision goggles, GPS devices and mobile phones. Rhino owners and authorities counter with intelligence sources, vehicle recognition systems, radar, infrared cameras and drones.
Financial desperation and coercion drive many poachers, who often live in the same communities as anti-poaching patrol members.
“Do they know it’s wrong? Mostly yes, but hunger or money can make people put their conscience aside,” said Prof Larkin.
The poachers “aren’t averse to using violence to get their way”, he said, adding that the syndicates typically engage in human trafficking and drug and arms dealings alongside wildlife smuggling.
The criminal networks operate in tiers, from poachers on the ground to mid-level dealers to international traffickers who move the horns to end-user markets, primarily in Asia.
“Some of the criminal network leaders are known but, as with all organised crime, it is very difficult to obtain solid evidence against the ring leaders as they are always removed from the actual poaching events,” said Mr Cooke, likening them to “mafia-type enterprises”.
Conservation efforts have shown some success. The mass dehorning of rhinos in Hluhluwe-Imfolozi Park last year – a painless but expensive procedure that must be redone every 18 to 24 months – resulted in an 80 per cent drop in poaching, saving an estimated 120 rhino lives.
SINGAPORE’S GEOGRAPHY PROBLEM
Singapore’s emergence as a transit hub stems from geography and connectivity rather than intent.
“There are very few direct flights from Southern Africa to the Far East, so passengers are routed via these transit nodes,” Prof Larkin said, citing Singapore alongside Hong Kong and Dubai as transit points for smugglers.
Ms Priya Kannan, senior investigation officer at local wildlife non-governmental organisation Animal Concerns Research and Education Society (ACRES), said that Singapore sits “at the heart of our region’s shipping route”, making it a hotspot for illegal wildlife trafficking through both air and sea cargo.
Recent cases underscore the challenge. In January 2024, South African national Gumede Sthembiso Joel was jailed for 24 months – Singapore’s heaviest sentence for wildlife smuggling to date – after pleading guilty to transiting through Singapore with 20 rhino horns destined for Laos.
Ms Kannan said increased post-pandemic air traffic demands more resources at checkpoints. “This should also be paired with innovations in how we can better detect illegal wildlife,” she added. “Singapore has been progressive by having wildlife sniffer dogs and this is a great initiative.”
SINGAPORE’S MULTI-PRONGED DEFENCE
The National Parks Board (NParks) deploys the dogs at the borders, specially trained to detect wildlife and wildlife products such as elephant ivory or pangolin scales, said the agency’s director for wildlife trade Xie Renhui.
The canines’ sense of smell is estimated to be 10,000 to 100,000 times more acute than that of humans, which helps them locate items that may escape detection by radiographic scanners and visual inspections, she said.
The dogs were instrumental in detecting Gumede’s 2022 smuggling attempt, she added.
NParks has a “zero-tolerance stance” on using Singapore as a conduit to smuggle in wildlife, Ms Xie said. The agency’s approach combines legal enforcement, public education and collaboration with overseas enforcement agencies and NGOs.
Under the Endangered Species (Import and Export) Act, trafficking CITES-scheduled Appendix I species without permits carries penalties of up to S$200,000 per specimen and eight years’ jail – identical for transit, import and export cases.
Border screening relies on risk assessment frameworks with profiles and indicators targeting illegal wildlife trade, which are “developed and refined regularly”, Ms Xie said.
NParks’ Centre for Wildlife Forensics also works with international experts using DNA analysis to gain deeper insights into seizures and identify trafficking patterns.
“The fight against the illegal wildlife trade is transnational, and requires strong cooperation on the bilateral, regional and international levels,” Ms Xie said, noting the agency’s close collaboration with INTERPOL and overseas experts for investigations and enforcement.
She urged the public to ensure purchases contain no endangered species parts and to report suspected illegal wildlife trade to NParks.
