Reference excerpt

The Honghe Hani Rice Terraces are the system of Hani rice-growing terraces located in Yuanyang County, Honghe Prefecture, Yunnan, China. The terraces' history spans around 1,200 years. The total area stretches across 1,000,000 acres and four counties: Yuanyang, Honghe, Jinpin and Lüchun, although the core area of the terraces is located in Yuanyang County. In 2013, 16,603 hectares of the Honghe Hani Rice Terraces were listed as a World Heritage Site, because of their outstanding resilient construction, unique social-ecological system, and importance to the Hani people.

Description The Honghe Hani Rice Terraces are located on the southern banks of the Hong River, below the Ailao Mountains in southern Yunnan. The rough, mountainous terrain and high annual rainfall led to the creation of a complex terrace system for growing rice, with some locations having over 3000 terraces between the edge of the forest and the valley floor. Irrigation channels and artificial aquifers made out of sandstone distribute the water across the landscape. This system has been continually maintained and operated by the Hani people for over 1,300 years. The cultivation of rice is an important part of the Hani culture, theology, calendar, and political system. The terraces follow a distinct vertical structure that has allowed the landscape to persist for so long, incorporating forests, villages, terraces, and water supply. At the tops of the mountains (above 2000 meters in elevation), the forests are conserved, to act as a catchment for the rainfall and to "recharge" the fields and terraces below. An intricate system of canals and ditches divert the water into the terraces below. The villages in the region are usually constructed just below the forests, between 1400 and 2000 m. In the World Heritage Site, 82 villages, each with 50-100 households, are protected. The buildings are usually made of adobe and stone. Each household farms one or two terrace plots below, usually growing red rice and breeding cattle.

Worked examples

Example 1 — a first encounter with Honghe Hani Rice Terraces

Start with the simplest possible case. Write down what Honghe Hani Rice Terraces 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 Honghe Hani Rice Terraces 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 Honghe Hani Rice Terraces 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 Honghe Hani Rice Terraces

In research: Honghe Hani Rice Terraces 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 Honghe Hani Rice Terraces 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: Honghe Hani Rice Terraces is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural terraces, Globally Important Agricultural Heritage Systems, Major National Historical and Cultural Sites in Yunnan, so understanding it makes those chapters shorter.
In everyday life: Look for Honghe Hani Rice Terraces 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.
