Ivory trade

Ivory trade is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ivory trade rather than just read about it. In short: The ivory trade is the commercial, often illegal trade in the ivory tusks of the hippopotamus, walrus, narwhal, mammoth, and most commonly, African and Asian elephants. Ivory has been traded for hundreds of years by people in Africa and Asia, resulting in restrictions and bans.

Key takeaways

  • Ivory trade belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ivory trade to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ivory trade from memory before moving on to harder problems.

Reference excerpt

The ivory trade is the commercial, often illegal trade in the ivory tusks of the hippopotamus, walrus, narwhal, mammoth, and most commonly, African and Asian elephants. Ivory has been traded for hundreds of years by people in Africa and Asia, resulting in restrictions and bans. Ivory was formerly used to make piano keys and other decorative items because of the white color it presents when processed but the piano industry abandoned ivory as a key covering material in the 1980s in favor of other materials such as plastic. Also, synthetic ivory has been developed which can be used as an alternative material for making piano keys.

Elephant ivory

Elephant ivory has been exported from Africa and Asia for millennia with records going back to the 14th century BCE. Transport of the heavy commodity was always difficult, and with the establishment of the early-modern slave trades from East and West Africa, freshly captured slaves were used to carry the heavy tusks to the ports where both the tusks and their carriers were sold. The ivory was used for piano keys, billiard balls and other expressions of exotic wealth. At the peak of the ivory trade, pre-20th century, during the colonization of Africa, around 800 to 1,000 tonnes of ivory were sent to Europe alone every year. World wars and the subsequent economic depressions caused a lull in this luxury commodity, but increased prosperity in the 1960s and early 1970s saw a resurgence. Japan, relieved from its exchange restrictions imposed after World War II, started to buy up raw (unworked) ivory. This started to put pressure on the forest elephants of Africa and Asia, both of which were used to supply the hard ivory preferred by the Japanese for the production of hanko, name seal stamps used like a signature. Prior to this period, most name seals had been made from wood with an ivory tip, carved with the signature, but increased prosperity saw the formerly unseen solid ivory hanko in mass production. Softer ivory from East Africa and southern Africa was traded for souvenirs, jewelry and trinkets. While the massive demand for hanko drove the majority of Japan's consumption, ivory has also historically been used in the production of high-status cultural objects, including components for the Japanese tea ceremony (Chanoyu). This includes the custom-made lids (futa) for certain types of ceramic tea caddies (chaki), which remain objects of traditional value. The persistence of ivory use in such high-end cultural practices keeps the issue linked to contemporary conservation debates. By the 1970s, Japan consumed about 40% of the global trade; another 40% was consumed by Europe and North America, often worked in Hong Kong, which was the largest trade hub, with most of the rest remaining in Africa. China, yet to become the economic force of today, consumed small amounts of ivory to keep its skilled carvers in business.

African elephant

1980s poaching and illegal trade In 1979, the African elephant population was estimated to be around 1.3 million in 37 range states, but by 1989, only 600,000 remained. Although many ivory traders repeatedly claimed that the problem was habitat loss, it became glaringly clear that the threat was primarily the international ivory trade. Throughout this decade, around 75,000 African elephants were killed for the ivory trade annually, worth around 1 billion dollars. About 80% of this was estimated to come from illegally killed elephants. The international deliberations over the measures required to prevent the serious decline in elephant numbers almost always ignored the loss of human life in Africa, the fueling of corruption, the "currency" of ivory in buying arms, and the breakdown of law and order in areas where illegal ivory trade flourished. The debate usually rested on the numbers of elephants, estimates of poached elephants and official ivory statistics. Activists such as Jim Nyamu have described current ivory prices for poached ivory and the dangers such activists face from organized poaching. Solutions to the problem of poaching and illegal trade focused on trying to control international ivory movements through CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). Although poaching remains a concern in areas of Africa, it is not the only threat for the elephants who roam its wilderness. Fences in farmlands are becoming increasingly more common; this disrupts the elephants' migration patterns and can cause herds to separate.

Worked examples

Example 1 — a first encounter with Ivory trade

Start with the simplest possible case. Write down what Ivory trade claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ivory trade before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ivory trade ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ivory trade

In research
Ivory trade appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ivory trade in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ivory trade is common in secondary-school and first-year university syllabi. It links to neighbouring topics Black markets, Criminal occupations, Elephant conservation, so understanding it makes those chapters shorter.
In everyday life
Look for Ivory trade outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Ivory trade in simple terms?

The ivory trade is the commercial, often illegal trade in the ivory tusks of the hippopotamus, walrus, narwhal, mammoth, and most commonly, African and Asian elephants. Ivory has been traded for hundreds of years by people in Africa and Asia, resulting in restrictions and bans.

Why does Ivory trade matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Ivory trade?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
