Jaffa orange

Jaffa orange 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 Jaffa orange rather than just read about it. In short: The Jaffa orange (Arabic: برتقال يافا; Hebrew: תפוז יפו) is an orange variety with few seeds and a tough skin that make it highly exportable. It was developed by Palestinian farmers in mid-19th century Ottoman Palestine, and takes its name from the city of Jaffa where it was first produced for export.

Reference excerpt

The Jaffa orange (Arabic: برتقال يافا; Hebrew: תפוז יפו) is an orange variety with few seeds and a tough skin that make it highly exportable. It was developed by Palestinian farmers in mid-19th century Ottoman Palestine, and takes its name from the city of Jaffa where it was first produced for export. Jaffa oranges are known for their sweet taste. During the initial Zionist Jewish immigration to Palestine in the late 19th century, the business of maintaining orchards and exporting oranges was an integrated venture of Jews and Arabs based out of the Port of Jaffa. Today, the Jaffa orange is one of three main varieties of the fruit grown in the Mediterranean, alongside the navel and bitter orange. It is cultivated in Palestine, Israel, Cyprus, Iraq, Lebanon, Syria, Jordan and Turkey.

Characteristics

Jaffa oranges, also known as shamouti (شموطي), are practically seedless, with a flavour that has been described as "excellent" and "sweet and fine". The two other main orange varieties cultivated in the region are the navel orange and the bitter orange; the latter is grown in Iran for its peel. The Jaffa orange is distinguished by its oval shape and thick peel, which is deep orange in colour and normally very easy to remove from the fruit. Its tough skin makes it "especially suitable for export". As it produces very little juice and has a tendency towards delayed bitterness, it is unsuitable for juice production, although it does store well. Jaffa oranges are very cold-tolerant, allowing them to grow outside of the subtropical regions normally associated with growing oranges. Jaffa oranges are susceptible to Alternaria, a type of fungus, and are prone to alternate bearing.

History

Located at the crossroads between Africa, western Asia, and Europe, the Levant produced a number of commodities for export via imperial and global distribution networks throughout the late Ottoman period (1200–1900 CE). Among these were Nabulsi soap, sugar, barley, oranges, and cotton. Though cotton left was influential throughout the region, the only commodity that remains a symbol of production in Palestine is the Jaffa orange. The Jaffa orange was a new variety developed by Arab farmers after emerging in the mid-19th century as a mutation on a tree of the 'Baladi' variety near the city of Jaffa. While the sour orange (C. aurantium) was brought westward from China and India by local traders, who may have introduced it to Sicily and Spain, the Jaffa orange was developed from the sweet orange (C. sinensis) which was brought from China to the Mediterranean region by Portuguese explorer Vasco da Gama in 1498.

Ottoman period After the Crimean War (1853–56), the most important innovation in local agriculture was the rapid expansion of citrus cultivation. Foremost among the varieties cultivated was the Jaffa (Shamouti) orange, and mention of it being exported to Europe first appears in British consular reports in the 1850s. One factor cited in the growth of the export market was the development of steamships in the first half of the 19th century, which enabled the export of oranges to the European markets in days rather than weeks. Another reason cited for the growth of the industry was the relative lack of European control over the cultivation of oranges compared to cotton, formerly a primary commodity crop of Palestine, but outpaced by the Jaffa orange.

Exports grew from 200,000 oranges in 1845 to 38 million oranges by 1870. The citrus plantations of this time were primarily owned by wealthy Palestinian merchants and notables, rather than small farmers, as the fruits required large capital investments with no yield for several years. Fruits carrying the "Jaffa" label were first marketed in 1870 by a German Templer colony. An 1872 account of Jaffa by a European traveller notes that "Surrounding Jaffa are the orange gardens for which it is justly extolled, and which are a considerable source of wealth to the owners. The annual value of fruits grown in Jaffa was said to be 10,000 pounds." In the 1880s, American grower H. S. Sanford tried to cultivate the Jaffa orange in Florida. The prosperity of the orange industry brought increased European interest and involvement in the development of Jaffa oranges. In 1902, a study of the growth of the orange industry by officials outlined the different owners and their primary export markets as England, Turkey, Egypt and Austria-Hungary. While the traditional Arabic cultivation methods were considered "primitive," an in-depth study of the financial expenditure involved reveals that they were ultimately more cost-efficient than the Zionist-European enterprises that followed them some two decades later.

Mandatory Palestine According to the 1930 Hope Simpson Enquiry, "The cultivation of the orange, introduced by the Arabs before the commencement of Jewish settlement, has developed to a very great extent in consequence of that settlement. There is no doubt that the pitch of perfection to which the technique of plantation and cultivation of the orange and grapefruit have been brought in Palestine is due to the scientific methods of the Jewish agriculturist." Partnerships in growing and exporting these oranges were an example of Arab–Jewish cooperation despite rising political tensions.

By the end of 1928, Jews had acquired 3,000 hectares (30,000 dunams) of the region's 6,000 hectares (60,000 dunams) of orange orchards. Whereas before World War I, the price of a dunam of land in a fruitful orange grove was 50–75 pounds sterling, by 1929, the same groves were selling for 150–200 pounds sterling. In 1933, Jewish-owned orange production overtook Arab-owned orange production. By 1939, Jewish-owned and Arab-owned orange orchards in Palestine covered 30,000 hectares (75,000 acres), employed over 100,000 workers, and their produce was a primary export. During World War II (1939–1945) citrus-growing declined, and Arab-owned orange production overtook Jewish-owned production.

Post-1948 After the 1948 war, the orange-growing industry was presented as a "pioneering Labor-movement project" which was "void of any Arab presence". Significant ethnic cleansing of Palestinian Arabs by Jewish Zionists occurred following the Nakba between 1947–1948, and the establishment of the Israeli state in 1948. Many Palestinian Arab–owned farms were subsequently taken from their owners as part of dispossession of their lands.

Worked examples

Example 1 — a first encounter with Jaffa orange

Start with the simplest possible case. Write down what Jaffa orange 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 Jaffa orange 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 Jaffa orange 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 Jaffa orange

In research
Jaffa orange 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 Jaffa orange 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
Jaffa orange is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture in Israel, Crops originating from Asia, Flora of Western Asia, so understanding it makes those chapters shorter.
In everyday life
Look for Jaffa orange 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.
