Rodrigues

Rodrigues is a earth 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 Rodrigues rather than just read about it. In short: Rodrigues (French: Île Rodrigues [il ʁɔdʁiɡ]; Kreol rodrig: Rodrig) is an autonomous outer island of the Republic of Mauritius, of approximately 108 km2 (42 mi2) and about 560 km (350 mi) east of the main island of Mauritius. Along with the French overseas department of Réunion, Rodrigues and Mauritius are part of the Mascarene Islands.

Key takeaways

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

Reference excerpt

Rodrigues (French: Île Rodrigues [il ʁɔdʁiɡ]; Kreol rodrig: Rodrig) is an autonomous outer island of the Republic of Mauritius, of approximately 108 km2 (42 mi2) and about 560 km (350 mi) east of the main island of Mauritius. Along with the French overseas department of Réunion, Rodrigues and Mauritius are part of the Mascarene Islands. The Outer Islands of Mauritius are managed under the aegis of the Prime Minister of Mauritius through the Prime Minister's Office by the Outer Islands Development Corporation. Of volcanic origin, Rodrigues is surrounded by coral reef and some tiny uninhabited islands that lie just off its coast. The tenth District of Mauritius until 2002, it was granted autonomous status and has since been managed by the Rodrigues Regional Assembly for its everyday governance. The capital and largest city is Port Mathurin and the island was home to around 41,669 inhabitants in 2014 according to Statistics Mauritius. Its people, mostly of African descent, are Mauritian citizens and form part of the wider Mauritian Creole community. Its economy is based mainly on fishing, farming, handicraft and a developing tourism sector. The islands of Rodrigues, Agaléga and Saint Brandon form part of the larger territory of the Republic of Mauritius.

Etymology and history

Rodrigues was named after Portuguese explorer Diogo Rodrigues, who first came upon the uninhabited island in 1528, under direction of Portuguese Viceroy Pedro Mascarenhas (namesake of the Mascarene Islands). Many maps also describe it as Diego Roiz. From the 10th century, Arabs are known to have visited the Mascarene Islands. The Cantino planisphere of c. 1500 and some other contemporary maps clearly show the three islands of the Mascarenes as Dina Arobi (or Harobi), Dina Margabin and Dina Moraze. These are apparently corrupted transliterations or transcriptions of the Arabic ديفا هاراب Diva Harab ("Desert Island"), ديفا مغربين Diva Maghrebin ("Western Island") and ديفا ماشريق Diva Mashriq ("Eastern Island"). While the second clearly refers to Réunion, sources disagree about which of the other is Mauritius and which one Rodrigues, which are both to the east of Réunion and arranged in a somewhat stylised way on these maps. However, even in its original state, Rodrigues had some karst, while Mauritius even after suffering 500 years of deforestation can by no means be called "desert" even in a colloquial sense. The island was located again in February 1507. Part of the fleet of Afonso de Albuquerque and Tristão da Cunha, Diogo Fernandes Pereira's ship Cisne (Swan) spotted Réunion on 9 February after a cyclone had diverted their course forcing them to go around Madagascar, unlike the rest of the fleet. It has also been opined that this was due to a navigational error by Afonso de Albuquerque. The other two islands were subsequently rediscovered. The initial name was Diogo Fernandes; Domingo Froiz was given as a name some years later, and by 1528 it had been again renamed after the Portuguese navigator Dom Diogo Rodrigues and has remained so since. The orthography has been less stable at first, with the name being transcribed Diogo Rodríguez (Spanish maps), Diego Roiz, Diego Ruys (Dutch maps) (or even Diego Ruy's Island), Dygarroys or Bygarroys. Some early French sources called it Île Marianne. Due to the island lying far off the beaten track of seafarers at that time, it received few visits. From 1601, the Dutch began visiting the island somewhat more regularly for fresh supplies of food. In 1691, the Huguenot François Leguat and seven companions landed on the island, intending to set up a farming colony of Protestant refugees. Farming was not successful, but there was an abundance of tortoises, turtles, birds, fish and other seafood. During the 18th century, several attempts were made by the French to develop the island. African slaves (ancestors of the present population) were brought to Rodrigues to develop stock-breeding and farming. In 1735 a permanent French settlement was established, subordinated to Île Bourbon. In 1809, after a brief battle with the French, British troops took possession of Rodrigues. After British occupation, slavery was eventually abolished in 1834. By 1843, the population had declined to a low of 250. In 1883, the eruption of the Indonesian volcano Krakatoa was heard at Rodrigues Island and it is the furthest point, at almost 4,800 km (3,000 mi), at which the explosion was heard. The sound was described as "the roar of heavy guns". Naval ships were ordered to investigate as it was feared the sound was due to a ship in distress firing its guns. The noise remains the loudest sound in recorded history. In September 1897, solo sailor Joshua Slocum spent eight days on the island. He would later write, "At Rodriguez one may now find every convenience for filling pure and wholesome water in any quantity. Governor Roberts having built a reservoir in the hills, above the village, and laid pipes to the jetty, where, at the time of my visit, there were five and a half feet at high tide. In former years well-water was used, and more or less sickness occurred from it. Beef may be had in any quantity on the island, and at a moderate price. Sweet potatoes were plentiful and cheap; the large sack of them that I bought there for about four shillings kept unusually well. I simply stored them in the sloop's dry hold. Of fruits, pomegranates were most plentiful; for two shillings I obtained a large sack of them, as many as a donkey could pack from the orchard, which, by the way, was planted by nature herself." Early in 1968, HMS Cambrian, which was part of the Beira Patrol following the Unilateral Declaration of Independence of Rhodesia, was diverted to Rodrigues to quell a reported uprising by some of the populace. The uprising consisted of a number of individuals who had been arrested by the local authorities for breaking into a warehouse and appropriating a supply of sweet potatoes. Other locals went to the authorities and by violence released the arrested persons. At this point, it is believed that the authorities requested assistance which was provided by HMS Cambrian. On her early morning arrival, the ship's 4.5" guns were fired (with blanks, it is believed) and an armed landing party was provided. This resulted in the offenders being rounded up and imprisoned again.

Worked examples

Example 1 — a first encounter with Rodrigues

Start with the simplest possible case. Write down what Rodrigues claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Rodrigues 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 Rodrigues 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 Rodrigues

In research
Rodrigues appears in earth 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 Rodrigues 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
Rodrigues is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1809 establishments in the British Empire, Autonomous administrative divisions in Africa, Former Dutch colonies, so understanding it makes those chapters shorter.
In everyday life
Look for Rodrigues 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.
