Rhino horn trade thrives in Jo'burg

Rhino horn trade thrives in Jo'burg | Biology | Scoop.it
04 OCT 2013 00:00 HONGXIANG HUANG Johannesburg - In Chinatown, horn and ivory are sold openly and cheaply alongside fresh produce and crafts. Wildlife trafficking syndicates brazenly sell rhino horn and ivory at Chinese markets in Southern Africa's capital cities, in the face of global attempts to crack down on the illicit trade in endangered species. China is responsible for an estimated 70% of the world trade in ivory, and research by the international wildlife trade monitoring organisation Traffic indicates that nearly 80% of the reported seizures of illegal rhino horns in Asia between 2009 and late last year happened in China. The recent influx of Chinese immigrants to Southern Africa has seen the market grow. Who are the Chinese people involved, and how do they go about buying these illegal products? Chinese journalists on an undercover assignment discovered that the Bruma flea market and nearby New Chinatown in eastern Johannesburg are the hub of the illicit trade in rhino horns and ivory in South Africa. Transactions between African sellers and Asian buyers occur relatively openly and daily. From 9am to 5pm, sellers hang around the entrance to the Bruma flea market and eagerly surround Chinese people as they approach. "What are you looking for? Do you want xiangya? I have," says Mike, a seller who hails from the Democratic Republic of Congo. "Do you have xiniujiao?" we ask. Xiangya is the Chinese term for ivory, xiniujiao for rhino horn, and it is clear Mike, as well as many other shop owners, is familiar with the terms. "Xiniujiao ... any time but now. If you come back next month, maybe I could help you get some. Now it is impossible," says Mike. He opens a door that is covered by a hanging blanket and shows us into a secret room near his craft shop where he has a stock of worked ivory products: small sculptures of elephants, chopsticks, necklaces, bracelets. The prices are not too expensive, ranging from R200 a piece. Matt, a Zimbabwean who works in Mike's craft shop, says most of the rhino horns and ivory comes from his home country. He explains how he imports it: "There is a river that divides the two countries and we find a part where the water is not too deep and there is almost no security patrolling. We take off our clothes and carry the stuff on our shoulders across the river." His biggest concern appears to be that there are crocodiles in some parts of the river. Other shop owners in this market call out to us with offers of xiangya and xiniujiao. Ernest, another shop owner from the Congo, says: "Your Chinese friends may find it hard to get rhino horns, but we are Africans, we know how." Along Derrick Avenue in New Chinatown, home to many of Johannesburg's recent Chinese immigrants, we speak to Gong, a taxi driver whose business list includes clients from the local immigration office and the Chinese embassy. "It is easy to buy ivory and I could help you tell which ones are fake – I have been buying it for many years," he says. Ivory is just one of the businesses Gong has engaged in in South Africa since he immigrated six years ago. Like most Chinese in his community, he does not have a good educational background and barely speaks English. He used to assist a friend running a Chinese brothel until police closed it down. "Nowadays [the ivory trade] is more dangerous than drugs," he says. "Even if I could get it for you, I would not take the risk of selling it to an outsider like you rather than known partners. Ivory and rhino horns are like weed [dagga] and heroin." Gong says fewer Chinese people are directly involved in smuggling rhino horn these days, although some still buy from Vietnamese traffickers. Consumers would be advised to buy horn in China, where he could introduce us to sellers, he adds. Research released by the World Wide Fund for Nature in September indicates that the Vietnamese dominate the rhino horn trade, but non-Asians often find it hard to differentiate between Chinese and Vietnamese people. Chinese smugglers still dominate the abalone smuggling market in South Africa and, according to a police expert, up to 90% of abalone smugglers are connected with rhino horn because they share the same smuggling pipelines to Asia. Several residents of New Chinatown echo Gong's concern about the dangers involved in trading rhino horn. "Everyone knows that it is a crime. Some Chinese were arrested because of participating in the trade. You would be advised not to ask around," says Jing, who works in a massage parlour. Many employees of Chinese companies in South Africa avoid New Chinatown, so named to distinguish it from the original Chinatown in central Johannesburg, because of its reputation for being involved with smuggling and other dangerous business. "I would usually not go to the New Chinatown area. There is a mix of good people and various criminals," says Zhang Jinguo, the head of the Chinese Construction Bank in Johannesburg. Among the Chinese community of Johannesburg, it is common knowledge that the Chinese tend to buy ivory and rhino horn in Maputo, Mozambique. We visit the Saturday market at Praça 25 de Junho in Maputo, where we have learnt that buying such products is a "must-do" for employees of Chinese companies who are not well educated and have unskilled jobs. "The products are unique and cheap," says Chen, a frequent buyer in Maputo who works for a Chinese construction company. At the Saturday market, Kai, a 29-year-old working for a Chinese telecommunications company, is shooting a video to send to his families in China. "Hello dears, look where I am. This is the most famous ivory market here. I will bring you some good stuff," he says. Shop owners like Adam are visibly excited when they see a group of Chinese people approaching. "Come, we have heimu and xiangya," he says. He says the Chinese are generally interested in buying two things in Mozambique: heimu, or African blackwood, and xiangya. He also offers rhino horns at $15 000 a kilogram, though he says he does not keep it in the marketplace because it is too expensive. He opens a big box filled with various ivory products and displays them openly. However, when some Chinese customers lift the ivory too high he asks them to put them down, in case the police notice and make trouble. Dong is an employee of a Chinese national oil company and has been in Mozambique for almost four years. He is browsing with three colleagues and is interested in buying bracelets made of blackwood, animal horns and ivory. After bargaining, he buys two ivory bracelets for about R500 and his colleague also buys two. "We will need to take them apart and hide the pieces in the corners of our luggage. Then even if customs finds some we can still make them up into bracelets in China," Dong advises his less-experienced colleague. As Dong's group walks away, a nearby shop owner reminds them to hide their ivory bracelets inside their pockets, because if the police see them they will ask for money to "solve the problem". Policemen patrol the market all the time, but they seem more interested in asking foreigners for their passports and money than finding ivory. Most of the buyers know where the ivory comes from, but don't care about the slaughter of elephants. Kai, who bought ivory bracelets, admits that he does not feel guilty about buying illegal products even though he knows how the sellers get them. However, there are some Chinese who refuse to buy into the market. "These items are art from killing," says Xu, a friend and colleague of Kai. But he adds that there are few Chinese like him. Owing to the sensitivity of the investigations, real names cannot be disclosed. This investigation by the Oxpeckers Centre for Investigative Environmental Journalists was supported by the Forum for African Investigative Reporters and the Wits China-Africa Reporting Project

Peer-to-Peer Science: The Century-Long Challenge to Respond to Fukushima

Peer-to-Peer Science: The Century-Long Challenge to Respond to Fukushima | Biology | Scoop.it

More than two years after an earthquake and tsunami wreaked havoc on a Japanese power plant, the Fukushima nuclear disaster is one of the most serious threats to public health in the Asia-Pacific, and the worst case of nuclear contamination the world has ever seen. Radiation continues to leak from the crippled Fukushima Daiichi site into groundwater, threatening to contaminate the entire Pacific Ocean. The cleanup will require an unprecedented global effort.

Bionanotechnology: Progressively Thinner Layers Of Chitin Make Metallic Beetles Shine

Bionanotechnology: Progressively Thinner Layers Of Chitin Make Metallic Beetles Shine | Biology | Scoop.it

A team of researchers at the University of Costa Rica has found that the beetles' metallic appearance is created by the unique structural arrangements of many dozens of layers of exo-skeletal chitin in the elytron, a hardened forewing that protects the delicate hindwings that are folded underneath.

 

The beetles were captured in the University of Costa Rica's Alberto Brenes Mesén Biological Reserve, a tropical rainforest environment. "The metallic appearance of these beetles may allow them to be unnoticed, something that helps them against potential predators," says physicist and study leader William E. Vargas. The surface of their elytra "reflects light in a way that they look as bright spots seen from any direction," he explains. "In a tropical rainforest, there are many drops of water suspended from the leaves of trees at ground level, along with wet leaves, and these drops and wet leaves redirect light by refraction and reflection respectively, in different directions. Thus, metallic beetles manage to blend with the environment."

 

To interpret the cause of this metallic look, Vargas and his team assumed that a sequence of layers of chitin appears through the cuticle, with successive layers having slightly different refractive indices.. In these beetles, the cuticle, which is just 10 millionths of a meter deep, has some 70 separate layers of chitin—a nitrogen-containing complex sugar that creates the hard outer skeletons of insects, crabs, shrimps, and lobsters. The chitin layers become progressively thinner with depth, forming a so-called "chirped" structure.

 

"Because the layers have different refractive indices," Vargas says, "light propagates through them at different speeds. The light is refracted through—and reflected by—each interface giving, in particular, phase differences in the emerging reflected rays. For several wavelengths in the visible range, there are many reflected rays whose phase differences allow for constructive interference. This leads to the metallic appearance of the beetles."

 

This is similar to the way in which a prism breaks white light into the colors of the rainbow by refraction, but in the case of these beetles, different wavelengths, or colors of light are reflected back more strongly by different layers of chitin. This creates the initial palette of colors that enable the beetles to produce their distinctive hues. The mystery the researchers still needed to understand in more detail, however, was how the beetles could so perfectly create the structure causing the brilliant metallic tones of silver and gold.

 

Using a device they specially designed to measure the reflection of light when it strikes the curved surface of the beetles' elytra, Vargas and his colleagues found that as light strikes the interface between each successive layer (the first interface being the boundary between the outside air and the top chitin layer), some of its energy is reflected and some is transmitted down to the next interface. "This happens through the complete sequence of interfaces," Vargas says.

 

Because a portion of the light is reflected, it combines with light of the exact same wavelength as it passes back through layer upon layer of chitin, becoming brighter and more intense. Ocean waves can exhibit the same behavior, combining to produce rare but powerful rogue waves. In the case of the beetles, this "perfect storm" of light amplification produces not only the same colors but also the striking sheen and glimmer that we normally associate with fine jewelry.
