Xochimilco

Xochimilco 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 Xochimilco rather than just read about it. In short: Xochimilco (Spanish pronunciation: [sotʃiˈmilko]; Classical Nahuatl: Xōchimīlco [ʃoːtʃiˈmiːlko] ) is a borough (Spanish: demarcación territorial) of Mexico City. The borough is centered on the formerly independent city of Xochimilco, which was established on what was the southern shore of Lake Xochimilco in the precolonial period.

Key takeaways

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

Reference excerpt

Xochimilco (Spanish pronunciation: [sotʃiˈmilko]; Classical Nahuatl: Xōchimīlco [ʃoːtʃiˈmiːlko] ) is a borough (Spanish: demarcación territorial) of Mexico City. The borough is centered on the formerly independent city of Xochimilco, which was established on what was the southern shore of Lake Xochimilco in the precolonial period. Today, the borough consists of the 18 barrios, or neighborhoods, of this city along with 14 pueblos, or villages, that surround it, covering an area of 125 km2 (48 sq mi). The borough is in the southeastern part of the city and has an identity that is separate from the historic center of Mexico City, due to its historic separation from that city during most of its history. Xochimilco is best known for its canals, which are left from what was an extensive lake and canal system that connected most of the settlements of the Valley of Mexico. These canals, along with artificial islands called chinampas, attract tourists and other city residents to ride on colorful gondola-like boats called trajineras around the 170 km (110 mi) of canals. This canal and chinampa system, as a vestige of the area's precolonial past, has made Xochimilco a World Heritage Site.

The city and borough

The borough of Xochimilco was created in 1928, when the federal government reorganized the Federal District of Mexico City into sixteen boroughs. The Xochimilco borough was centered on what was the city of Xochimilco, which had been an independent settlement from the pre-Hispanic period to the 20th century. The area's historic separation from Mexico City proper remains in its culture. While officially part of the city, its identity is more like a suburb. This historic center was designated as a "Barrio Mágico" by the city in 2011. The borough is center-south of the historic center of Mexico City, and bordered by the boroughs of Tlalpan, Coyoacán, Tláhuac and Milpa Alta. It extends over 125 km2 (48 sq mi), accounting for 8.4% of the Federal District's territory. It is the third largest borough, after Tlalpan, and Milpa Alta. The borough has an emblem, also known as an Aztec glyph, which is a representation of the area's spongy soil from which two flowering plants emerge. In spite of the serious environmental issues, 77.9% of the territory is designated as ecological reserve, 15.2% as residential and 4.6 as commercial and industrial. The borough is divided into eighteen "barrios," which make up the old city of Xochimilco and fourteen communities outside the traditional city called "pueblos." The barrios are El Rosario, Santa Crucita, Caltongo, San Lorenzo, San Diego, La Asunción, San Juan, San Antonio, Belem, San Cristóbal, San Esteban, La Santísima, La Guadalupita, La Concepción Tlacoapa, San Marcos and Xaltocan, The fourteen pueblos are Santa María Tepepan, Santiago Tepalcatlalpan, San Mateo Xalpa, San Lorenzo Atemoaya, Santa Cruz Xochitepec, San Lucas Xochimanca, San Francisco Tlalnepantla, Santa María Nativitas, San Gregorio Atlapulco, Santiago Tulyehualco, San Luis Tlaxialtemalco, San Andrés Ahuayucan, Santa Cecilia Tepetlapa and San Cruz Acalpixca. There are also 45 smaller divisions called "colonias" and twenty major apartment complexes. The city acts as the local government for all the communities of the borough, whether part of the city or not. These offices are located on Calle Guadalupe I. Ramirez 4, in the El Rosario area. The borough has 11.4 km (7.1 mi) of primary roadway and 4,284,733 square metres (1,058.8 acres) of paved surface. Major thoroughfares include the Xochimilco-Tulyehualco road, Nuevo León, Periférico Sur, Avenida Guadalupe and Calzada México-Xochimilco. However, many of the areas of the borough are still semi-rural, with communities that still retain many old traditions and economic activities. For example, San Antonio Molotlán is noted for textiles and its Chinelos dancers. San Lorenzo Tlaltecpan is known for the production of milk and there are still a large number of stables in the area.

Worked examples

Example 1 — a first encounter with Xochimilco

Start with the simplest possible case. Write down what Xochimilco 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 Xochimilco 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 Xochimilco 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 Xochimilco

In research
Xochimilco 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 Xochimilco 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
Xochimilco is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aztec sites, Boroughs of Mexico City, Canals, so understanding it makes those chapters shorter.
In everyday life
Look for Xochimilco 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.
