Toads for watermelon October 13th, 2019 by

The south coast of Jamaica is just right for growing watermelon, where I recently saw the fruit stacked under the shade trees in front of comfortable farm houses. Farmers can earn a tidy living from selling melons on the local market and to the hotels and resorts.

But the trick is to get enough water. In the dry season, a tanker truck will deliver 1000 gallons (almost 4,000 liters) for $50. Most of the farmers economize on water by using drip irrigation. For many years, farmers have saved on water by using mulch, made from the light-weight Guinea grass.

Professional crews cut and dry the grass, which is grown in small fields scattered among the patches of watermelon.  The grass crews lay out a neat carpet of mulch, which not only keeps the soil moist, but also suppresses weeds, and creates a soft, clean bed for the fruit to grow, so it develops an attractive, green rind all the way around the fruit. After harvest, the grass decomposes, enriching the soil with organic matter.

I learned about this while visiting Jamaican farmer Junior Dyer, with a group of colleagues. We asked when Junior watered his plants. He said at 9 or 10 AM. “I never water at night,” Junior explained, because if he does that frogs and toads come into the field to eat the insect pests, but then the amphibians stay for the night, digging holes into the moist soil and disturbing the roots. The frogs and toads still come and eat the insect pests when watering is done in the morning, but then they bed down on the edge of the field.

Junior also showed me some of his 13 beehives, which he moves around to pollinate his melons, cantaloupe and cucumbers. I asked Junior if he used insecticides to control major insect pests such as whiteflies, thrips and especially aphids, which transmit disease (like watermelon mosaic virus). He admitted, a bit reluctantly, that he did use insecticides. I asked how he managed that without killing his bees. Junior replied that he looks for insecticide labelled as bee-friendly. In truth, insecticides are never good for bees, but some are less toxic than others.

Junior’s extension agent, Jermaine Wilson, said that Junior belongs to a farmers’ group, but that the farmers had already observed on their own that toads and frogs are beneficial creatures. Farmers see them eating insects. Beneficial amphibians are an example of how valuable local knowledge often develops around a topic that is culturally important (like watermelon pests) and easy to observe (like toads eating bugs). I found it encouraging that Junior appreciated the frogs and toads, even though they tend to eat larger insects rather than the really small ones that are the main pests in Jamaican watermelon.

I admired the efficient system the Jamaicans have for producing watermelon, even though they still largely rely on insecticides, with little organic production. But the Jamaican farmers are moving in the right direction by encouraging frogs and toads, and beekeeping will certainly motivate them to further reduce insecticides. Watermelons are a fairly sustainable, commercial crop from family farms. The bees pollinate the melon flowers, and the fruit grows nestled in a bed of mulch, precision-watered with drip irrigation. It’s a nice blend of appropriate technology and local knowledge, with frogs and toads contributing along the way.

Gauchos for hire October 6th, 2019 by

Picture a gaucho astride a horse on a homemade saddle, galloping like a centaur across the limitless plains of Argentina. Above his broad brimmed hat, he twirls three balls (bolas) tethered together, to fling at the feet of a fleeing bull. The rawhide cords of the bolas wrap around the lower legs of the bull and bring it crashing to the ground.

The gauchos are often portrayed as a romantic even mythical figure, so it is easy to forget that they were workers in commercial agriculture, supplying the world’s markets with export beef, even in the early nineteenth century.

Argentine historian Ricardo Salvatore has written a book about the final, glory days of the gauchos (1829 to 1852), when Argentina was governed by Juan Manuel de Rosas. Now largely vilified in his home country as a dictator and populist, Rosas liberalized markets and freed them from the restrictions and high prices imposed under colonial rule. He awarded government contracts in public, on the steps of the police station, to those who submitted the lowest tender. Rosas insisted that the courts give equal legal treatment to rich and poor, black and white. He created a large army and filled it with rural men, but he also fed their widows and families with beef confiscated from enemy ranchers.

The Argentine civil wars dragged on for decades. Rosas and his party, the Federales, favored less government. They would eventually lose to the rebel Unitarios, who wanted a strong central administration. During the war many rural people, paisanos, migrated to the relative calm of the province of Buenos Aires. Along the way young men were arrested on charges of deserting the army. Fragments of their defense statements, transcribed by court clerks, make up most of the source material for Salvatore’s book.

The gauchos were, by Salvatore’s definition, illiterate. They also worked as ranch and farm hands, and led a simple life. They owned little more than some simple horse-riding tack and the clothes on their back: a shirt, jacket, poncho, home-made boots and a chiripá (a woven cloth worn around the waist, and tucked between the legs).

The vast pampas may have been unfenced but they were policed by small town judges (jueces de paz), and owned by ranchers, who employed the gauchos to raise cattle, and to grow a few crops. Products like dried beef, hides and tallow were carted to Buenos Aires and exported, mainly to Europe. Live cattle were herded to the city. On one single day, 27 February 1847, a whopping 19,073 animals were slaughtered. It’s not clear if this was a routine toll or just a bad day for cows. In those days the meat was salted and exported, before the invention of tinned food and refrigerated shipping.

During the long, violent wars of independence from Spain (about 1809 to 1825), all of the mainland Spanish-American countries, from Mexico to Argentina, emerged as self-governing republics. In Argentina, the struggle for independence had fostered an ideology of equality, which the gauchos held onto during the civil wars that broke out soon after independence was granted. Labor shortages also strengthened the gaucho’s position with their employers. Some would demand advance pay and then vanish. Others insisted on being paid daily, to earn more than the monthly salaries that ranch owners preferred. Employers also lured the gauchos into jobs with rations of beef, tobacco, and sugar. But money and rations weren’t enough to keep gauchos on the job. They insisted on being addressed respectfully. A foreman who barked out orders like a rude command could be challenged to a knife duel by a weather-worn gaucho.

In the mid 1800s, the Argentine ranch owners purposefully played down differences in social status. The ranchers wore the same clothes as their workers, ate almost nothing but meat, and lived in houses where the only furniture was a saddle hanging on the wall.

After the Argentine civil wars ended, Salvatore says that the gauchos faded from history. Deserters were no longer of interest to the small-town judges. And the distinction between Federal and Unitario was less important, so rural travelers stopped being arrested and questioned. Gauchos appear infrequently in the police records, now mostly described as “vagabonds.”

After the 1860s, the beef economy rapidly modernized, with the introduction of barbed-wire fences and railroads. Scottish, Irish and English migrants took over many of the gaucho’s jobs in the countryside. Italians worked in the city in commerce and in packing plants.

The gauchos migrated to the towns and to the frontiers and eventually intermarried with the newcomers. The gauchos were no longer a distinct social group by the end of the 19th century. Gone but not forgotten. Modern Argentina still has an egalitarian touch; even the waiters approach their customers tall and proud, addressing their customers like friends.  Perhaps the tough, friendly spirit of the gauchos lives on, at least a bit.

Spanish mulch September 22nd, 2019 by

Linguists will tell you that each language arranges the world differently. No two languages classify objects, activities or emotions in the same way. This is especially true of the words used in farming.

I was reminded of this recently when translating a video script from English to Spanish. The video, from northern India, forced me to grapple with “mulch”, an English word that is also widely used in Spanish, in real life and on the Internet.  Yet the world’s authority on the Spanish language, the Real Academia Española, does not include “mulch” in its magnificent dictionary, the Diccionario de la Real Academia de la Lengua Española.

It is odd that “mulch” is a new word in Spanish, when it is an old word in English. The Oxford English Dictionary defines mulch as a “Partly rotted plant material, etc.; (Horticulture) loose material consisting of straw, decaying leaves, shredded cuttings and bark etc., spread on soil or around or over a plant to provide insulation, protect from desiccation and deter weeds.” “Mulch” comes from a Middle English word, “molsh” or “mulsh” and has been in the language at least since 1440, and possibly much earlier.

I had my doubt about using “mulch” in Spanish. Various on-line dictionaries suggest “mantillo”, literally “little blanket” instead. But a web search of mantillo usually shows commercial bags of chipped bark used for landscaping and suppressing weeds. Not quite the same as the straw, leaves and husks that farmers have on hand.

I wrote to three agronomists I respect, native Spanish speakers who work closely with farmers. They confirmed that “mulch” was the word to use in Spanish. But one offered a little twist: if the video from northern India was being translated into Quechua, we could say “sach’a wanu.” Now there is a term to savor. “Wanu” means dropping, and is the source of the English word “guano,” meaning bird dung. In Quechua, “wallp’a wanu” is chicken dung, “llama wanu” is llama dung, and “sach’a wanu” is forest mulch, or the fallen leaves of trees.

I was back where I started. So, I decided to use “mulch” in the script, although at the first mention I did offer the alternative “mantillo.”

While languages describe the world in different ways, they also level those differences as they aggressively borrow words from each other, for example “silo”, “lasso”, and “stevedore.” These are all recent loanwords from Spanish to English. New words take time to be defined in dictionaries, which cautiously avoid including fad words that may fade away before really entering the language. But one day “mulch” will be included in the Diccionario de la Real Academia, joining “whisky,” “sandwich,” and other recent English loan words that have enriched the Spanish language.

Mulch for a better soil and crop

Two heads film better than one September 15th, 2019 by

Vea la versión en español a continuación.

I used to think that committees and group work killed creativity, but teamwork can help individuals produce things – like a cool video – that they couldn’t do by themselves.

Late last year, I was part of a team making a video in the southern Altiplano of Bolivia, along with Paul (the director), Marcella (the cameraperson) and Milton Villca. Milton is an agronomist who grew up in a village on the windswept plains where we were filming. He still lives in the area, helping local farmers to cope with challenges, especially the immense loss of soil caused by wind erosion.

After watching Marcella film for two days, Milton confided that he had tried making his own video, about a wasp that attacks and helps to control some of the caterpillar pests of the quinoa crop. But like the farmers, Milton had also struggled with the wind, losing two cameras because of damage by the fine sand. He’d continued filming the wasps with his cell phone, but he told Marcella he wasn’t sure about the quality of the images. Would she mind taking a look at them?

Marcella was happy to watch Milton’s video clips. All was fine. There were fabulous close ups of a wasp that digs a tunnel in the earth, hides it with grains of sand, finds a big, fat caterpillar, paralyzes it, and drags it back to the burrow, which the wasp is miraculously able to find, with the precision of a GPS. The video clips showed how the wasp uncovers the nest, inserts the unfortunate caterpillar, and lays an egg on it. A wasp grub hatches from the egg, eats the caterpillar and eventually emerges in the summer as an adult wasp.

Paul was immediately taken by the story of the wasp, which locals call nina nina. In our interviews with farmers for a video on windbreaks he decided to also ask them what they knew about the wasp. Unlike many parasitic wasps, which are too small to see clearly with the naked eye, the nina nina is pretty big, and local people know about it and can describe its ecology.

Asking a professional cameraperson to critique your videos can be daunting, but Milton no doubt sensed that Marcella would give him sympathetic and positive criticism. His risk paid off. We collaborated with Milton to write a script for his video. Marcella edited his clips and combined them into a short video, which we are proud to release this week.

DOS CABEZAS FILMAN MEJOR QUE UNA

Por Jeff Bentley, 15 de septiembre del 2019

Yo solĂ­a pensar que los comitĂ©s y el trabajo en grupo mataban la creatividad, pero el trabajo en equipo puede ayudar a los individuos a producir cosas – como un video genial – que no podrĂ­an hacerse por sĂ­ mismos.

A finales del año pasado, formé parte de un equipo que hacía un video en el Altiplano sur de Bolivia, junto con Paul (el director), Marcella (la camarógrafa) y Milton Villca. Milton es un técnico agrónomo de un pueblo del altiplánico ventoso donde filmábamos. Él todavía vive en la zona, ayudando a los agricultores locales a manejar sus desafíos, especialmente a la inmensa pérdida de suelo causada por la erosión del viento.

Después de ver a Marcella filmar durante dos días, Milton confió que él había intentado hacer su propio video, sobre una avispa que ataca y ayuda a controlar algunos de los gusanos plagas del cultivo de la quinua. Pero al igual que los agricultores, Milton también había luchado contra el viento, perdiendo dos cámaras debido a los daños causados por la arena fina. Había seguido filmando las avispas con su celular, pero le dijo a Marcella que no estaba seguro de la calidad de las imágenes. ¿Ella estaría dispuesta a verlas?

A Marcella le encantaron los videos de Milton. Hubo excelentes primeros planos de una avispa que excava un tĂşnel en la tierra, lo esconde con granos de arena, encuentra una oruga grande y gorda, la paraliza y la arrastra hasta el tĂşnel del nido, que la avispa milagrosamente logra encontrar, como si tuviera un GPS. Los videos muestran cĂłmo la avispa descubre el nido, inserta al desafortunado gusano y pone un huevo en Ă©l. Luego, la crĂ­a de la avispa sale del huevo, se come al gusano y eventualmente emerge como una avispa adulta en el verano.

A Paul le cautivó inmediatamente la historia de la avispa, a la que la gente local llama nina nina. En nuestras entrevistas con los agricultores para un video sobre las barreras vivas, decidió también preguntarles lo que sabían sobre las avispas. A diferencia de muchas avispas parásitas, que son demasiado pequeñas para ver claramente a simple vista, la nina nina es bastante grande, y la gente local sabe de ella y puede describir su ecología.

Pedirle a un camarĂłgrafo profesional que critique sus videos puede ser desalentador, pero Milton sin duda sintiĂł que Marcella le darĂ­a una crĂ­tica positiva, con empatĂ­a. Su riesgo valiĂł la pena. Colaboramos con Milton para escribir un guion para su vĂ­deo. Marcella editĂł sus clips y los combinĂł en un video corto, que estamos orgullosos de lanzar esta semana.

Native potatoes, tasty and vulnerable September 8th, 2019 by

Vea la versión en español a continuación

Of well over 4000 potato varieties, the great majority only grow in the Andes, a cordillera of great heights (with farming up to 4500 meters above sea level) and tropical latitudes (with little variation in daylight hours between summer and winter). Potato varieties adapted to these special conditions can rarely survive outside the Andes.

The native varieties are endangered, and if they disappear, they will take with them the genes that breeders need to create the varieties adapted to a changing world.

But the Andean farmers fear the extinction of native potatoes for other reasons. Near Cusco, Santiago Huarhua and Ernestina Huallpayunca, with their children, tell us that native potatoes are much nicer to eat than the modern varieties. The native potatoes are of many colors, even red and blue. They are floury and tasty. Don Santiago and doña Ernestina produce them only with natural fertilizer, which they say helps to preserve the potato’s special flavor. The couple grows the potatoes on the high mountain slopes above their village, while the so-called improved potatoes are white and are produced with chemical fertilizer, on the valley bottom.

Even though the family preserves native potatoes, they grow more of the improved ones, because of market demand, to make fried potatoes and chips. The native potatoes tend to be smaller and too dry to fry, but perfect for boiling.

Don Santiago says that when he was a child, there were many native potato varieties, more than he can remember, but now there are only five. He shows us where he keeps his seed potato. He has three shelves, each about one by two meters, enough to plant about 1500 square meters of each variety; that makes one small plot for each kind of potato. The survival of these vulnerable varieties depends on a few kilos of seed, curated by relatively isolated households.

In recent years, Peruvians have started to appreciate these little gourmet potatoes, and buy them. This new demand for native potatoes helps to ensure their survival, but varieties are still being lost. Yet native potatoes do have one thing in their favor: farmers like them more than other varieties.

PAPAS NATIVAS, DELICIOSAS Y VULNERABLES

Por Jeff Bentley, 8 de septiembre del 2019

De las mucho más de 4000 variedades de papa, la gran mayoría solo viven en los Andes, una cordillera con grandes alturas (con agricultura hasta 4500 msnm) y latitudes tropicales (con poca variación de horas luz entre invierno y verano). Las variedades adaptadas a estas condiciones especiales raras veces sobreviven en otros lugares.

Las variedades nativas están en peligro de extinción, y si se desaparecen, llevarán consigo los genes que los fitomejoradores necesitarán para crear variedades aptas a un mundo cambiante.

Pero los agricultores andinos temen la extinción de la papa nativa por otras razones. Cerca de Cusco, Santiago Huarhua y Ernestina Huallpayunca, con sus hijos, nos explican que las papas nativas son mucho más ricas que las mejoradas. Las nativas son de muchos colores, hasta rojo y azul. Son harinosas y sabrosas. Don Santiago y doña Ernestina las producen solo con abono natural, que según ellos ayuda a preservar su sabor especial. Las cultivan en las alturas, en los cerros arriba de su comunidad, mientras las papas mejoradas son blancas, y se producen con fertilizante químico, en el piso del valle.

A pesar de que la familia preserva papas nativas, más producen papas mejoradas, porque es lo que el mercado demanda, para hacer papa frita. Las papas nativas tienden a ser pequeñas y no muy buenas para freír, pero perfectas para sancochar.

Don Santiago nos cuenta que cuando era un niño, había muchas variedades nativas. No se acuerda cuántas, pero ahora solo quedan cinco. Nos muestra donde guarda su papa, para semilla. Tiene tres estantes, cada uno de un metro por dos, suficiente para sembrar 1500 metros cuadrados de cada variedad; es una parcela pequeña para cada clase de papa. La sobrevivencia de estas variedades vulnerables depende de unos cuantos kilos de semilla, custodiadas por familias relativamente aisladas.

El preservar a las papas nativas será una actividad social. Nadie lo puede hacer solo. El público tendrá que aprender a apreciar estas papitas gourmet, y comprarlas. Los agricultores tendrán que tener acceso a la semilla de otros lugares cuando su papa se degenera y hay que cambiarla.

En los últimos años, los consumidores peruanos han empezado a querer a esas pequeñas papas gourmet. Esta nueva demanda para la papa nativa ayuda a asegurar su sobrevivencia, pero se siguen perdiendo variedades. Sin embargo, la mejor ficha que tienen las papas nativas es que los mismos agricultores las prefieren a las otras variedades.
