“You drive me bananas!”
After I first began studying English in elementary faculty, this was one of many English idioms that basically caught out to me as a result of it included a fruit. Different fruit-related phrases and idioms that piqued my curiosity included the basic, “You’re the apple of my eye!” and “He’s simply cherry selecting”.
Whereas there isn’t any scarcity of English fruit-related idioms, the number of bananas offered in lots of fashionable grocery shops right this moment is unfortunately, dismal. Though there are greater than 1000 types of bananas on the planet, 99% of bananas offered for export right this moment are of the Cavendish selection, pictured under.
If I can stroll right into a modern-day grocery retailer and simply discover completely different types of apples starting from Granny Smith, Purple Scrumptious, Fuji to Honeycrisp apples, why is it so laborious to search out various kinds of bananas within the Western world? There are numerous cultivars of bananas loved world wide starting from Musa velutina, a kind of fuzzy and stubby pink banana, to Blue Java, a cold-tolerant cultivar that has an ice cream consistency and seems blue when unripened.

The banana is the world’s hottest fruit and accounts for ¾ of the world’s tropical fruit commerce. Actually, it’s the fourth most useful meals crop on the planet, solely standing behind wheat, rice and milk. For one thing so widespread, why aren’t extra cultivars of bananas seen in American grocery shops?
We first have to know the place bananas are grown. Bananas develop greatest in scorching humid climates such because the tropical areas of Africa, Latin America, the Caribbean and the Pacific. Because of this many of the bananas you see in the US are usually not grown on US soil, however really imported from elsewhere. Actually, many of the bananas grown on the planet are consumed the place they develop, and exports solely make up 15% of the worldwide banana output. The explanation that the majority banana exports are of the Cavendish selection that American customers are so aware of is a narrative of hyper-optimization.
In comparison with another banana cultivars, Cavendish crops are quick, in order that they don’t topple over simply in a hurricane. The Cavendish is taken into account barely delicate in taste in comparison with another cultivars, and thus extra palatable to international customers. Its lengthy shelf life makes it simple to ship and retailer.

Furthermore, whereas many wild banana cultivars have seeds and are sexually reproduced, the Cavendish cultivar is seedless and thus sterile. Because of this Cavendish bananas have to be propagated by slicing – primarily slicing off the stems, roots or leaves of an current plant and utilizing them to begin new crops. How does that seem like precisely? New banana crops develop on the base of the plant and are referred to as banana pups, often known as suckers. These will be eliminated and planted to develop an entire new banana plant. To present an analogy, that’s equal to somebody slicing off a small a part of you and utilizing it to develop one other you who’s genetically an identical.

Since many of the Cavendish grown on the planet are primarily clones of each other, this makes them a really perfect crop to develop on a big scale. Farmers know precisely how a plot of banana crops would reply to a sure degree of pesticide, how the bananas would fare after 5 days of refrigerated transport, and so on. Briefly, uniformity makes farmers’ jobs simpler – they make bananas predictable, facilitated systemized methods of harvesting, transportation and storage, and in the end driving bottom-line progress.
Nonetheless, uniformity can even kill.

The best menace to banana plantations for the previous century might be the Panama illness, a wilting illness attributable to the fungus Fusarium oxysporum f. sp. Cubense. This soil-borne fungus has been a significant concern up to now and is rearing its ugly head once more. In recent times, the Tropical Race four (TR4) pressure of the Panama illness has been wreaking havoc in banana plantations.
TR4’s assault on banana crops (Picture Supply)
The Fusarium spores infect banana crops and colonize their xylem vessels, limiting the circulate of water and vitamins. This leads to blackened and discolored vascular tissue within the plant, and in the end the plant is destroyed. Not solely can this soil-borne fungus be transmitted by planting supplies, footwear, automobiles or by water, the fungus can stay dormant within the soil for over 30 years till a prone banana plant is planted close by (silent, however lethal!). There may be at present no viable absolutely efficient therapy of both the plant or soil to manage for TR4. Thus, the very best administration follow proper now to quarantine contaminated plant materials or soil and stop switch into TR4-free areas.
You could be questioning – No biggy, it’s simply bananas. Whereas for a few of us, bananas might signify the final word low-cost and wholesome handy meals or one thing to provide your morning smoothie extra physique and texture, bananas are an economically vital crop for a lot of the world. Bananas kind a good portion of export revenues for a lot of Caribbean and Latin American international locations. As an example, banana exports alone make up about 25% of Ecuador’s whole non-petroleum exports. In Ecuador alone, the banana trade is reported to generate 2 million direct and oblique jobs.
In addition to being a significant supply of earnings for a lot of households, bananas are additionally a supply of meals safety and vitamin for many individuals. Practically nine-tenths of the world’s bananas are eaten in poor international locations. No less than 400 million folks depend on bananas for 15-27% of their every day energy.

The Panama illness TR4 was first found in Taiwanese soil samples as early as 30 years in the past, and for a very long time, its damaging energy was restricted to Southeast Asia and Australia. In 2013 nonetheless, instances have been confirmed within the Center East and Africa, and in 2019, the illness arrived in Latin America, the place not less than 70% of the world’s bananas are grown.
A part of what accelerated the unfold of TR4 is the truth that many banana plantations right this moment are primarily monocultures. The Cavendish cultivar accounts for 47% of worldwide banana manufacturing and 99% of banana exports. Recall that the Cavendish cultivar are seedless varieties that should be propagated by slicing, primarily leading to each banana plant being genetically an identical. The dearth of genetic range means if yow will discover a virus that may kill one plant, you’ll be able to kill all of them.
We solely must look again to the 1950s to see how this has already occurred as soon as. Previous to the proliferation of the Cavendish cultivar, many of the world really loved bananas of one other selection – the Gros Michel. This was the usual banana offered within the US from 1870 till the late 1950s, when the Panama illness worn out many plantations. Many say that Gros Michel tasted far superior to Cavendish. One particular person on a web-based banana discussion board even supplied to pay an arm and a leg simply to strive at Gros Michel banana.

Much like the Gros Michel, the monoculture of Cavendish makes them susceptible to assault. Whereas it’s simple to sentence monoculture, present provide chain programs make it very costly to domesticate a number of types of bananas. The banana infrastructure right this moment from propagation, to harvesting, transport and storage have been totally optimized for the Cavendish. That is what makes it doable to get a banana at Walmart for simply 19 cents (nonetheless unbelievable each time I give it some thought).
It might seem to be the times are numbered for Cavendish, however nonetheless, researchers world wide try to avoid wasting this specific kind of banana that many people love world wide. A group of researchers in Australia has taken a gene from a wild banana (that’s immune to TR4) and inserted into the Cavendish cultivar to provide bananas which are extra immune to TR4. The Honduras Basis for Agricultural Analysis in La Lima has spent over three years creating a TR4-resistant selection that may resemble the Cavendish as a lot as doable. Leena Tripathi, a molecular biologist on the Worldwide Institute of Tropical Agriculture in Kenya is utilizing gene-editing instruments like CRISPR to suppress sure Cavendish genes that make them prone to TR4.

Who is aware of what the long run will seem like? Maybe we’ll transfer to a mannequin of multicultures, albeit at a better price to customers. Maybe there’s a scientific workaround, we save the Cavendish and monoculture proceed to persist. Maybe we discover one other selection that’s equally palatable, shippable and scalable. Nonetheless, the specter of shedding our quick access to reasonably priced bananas actually drives dwelling how handy our lives have been made by the worldwide scale-up of banana manufacturing.
