Strawberry fields once again March 15th, 2020 by

Vea la versión en español a continuación

Like many Bolivians, Diego Ramírez never thought about remaining in the village where he was born, and starting a business on his family’s small farm. As a kid, he loved picking fruit on his grandparents’ small strawberry patch in the village of Ucuchi, and swimming with his friends in a pond fed with spring water, but he had to leave home at a young age to attend high school in the small city of Sacaba, and then he went on to study computer science at the university (UMSS) in the big city of Cochabamba, where he found work after graduation.

Years later, Diego’s dad called his seven children together to tell them that he was selling their grandparents’ farm. It made sense. The grandparents had died, and the land had been idle for about 15 years. Yet, it struck Diego as a tragedy, so he said “I’ll farm it.” Some people thought he was joking. In Ucuchi, people were leaving agriculture, not getting into it. Many had migrated to Bolivia’s eastern lowlands or to foreign countries, so many of the fields in Ucuchi were abandoned. It was not the sort of place that people like Diego normally return to.

When Diego decided to revive his family farm two years ago, he turned to the Internet for inspiration. Although strawberries have been grown for many years in Ucuchi, and they are a profitable crop around Cochabamba, Diego learned of a commercial strawberry farm in Santo Domingo, Santiago, in neighboring Chile, that gave advice and sold plants. Santo Domingo is 2450 km from Cochabamba, but Diego was so serious about strawberries that he went there over a weekend and brought back 500 strawberry plants. Crucially, he also learned about new technologies like drip irrigation, and planting in raised beds covered with plastic sheeting. Encouraged by his new knowledge, he found dealers in Cochabamba who sold drip irrigation equipment and he installed it, along with plastic mulch, a common method in modern strawberry production.

Diego was inclined towards producing strawberries agroecologically, so he contacted the Agrecol Andes Foundation which was then organizing an association of ecological farmers in Sacaba, the small city where Diego lives (half way between the farm and the big city of Cochabamba). In that way Diego became a certified ecological farmer under the SPG PAS (Participatory Guaranty System, Agroecological Farmers of Sacaba).  Diego learned to make his own biol (a fermented solution of cow dung that fertilizes the soil and adds beneficial microbes to it). Now he mixes biol into the drip irrigation tank, fertilizing the strawberries one drop at a time.

Diego also makes his own organic sprays, like sulfur-lime brew and Bordeaux mix. He applies these solutions every two weeks to control powdery mildew, a common fungal disease, thrips (a small insect pest), red mites, and damping off. I was impressed. A lot of people talk about organic sprays, but few make their own. “It’s not that hard,” Diego shrugged, when I asked him where he found the time.

Diego finds the time to do a lot of admirable things. He has a natural flair for marketing and has designed his own packing boxes of thin cardboard, which he had printed in La Paz. His customers receive their fruit in a handsome box, rather than in a plastic bag, where fruit is easily damaged. He sells direct to customers who come to his farm, and at agroecological fairs and in stores that sell ecological products.

Diego still does his day job in the city, while also being active in community politics in Ucuchi. He also tends a small field of potatoes and he is planting fruit trees and prickly pear on the rocky slopes above his strawberry field. Diego has also started a farmers’ association with his neighbors, ten men and ten women, including mature adults and young people who are still in university.

The association members grow various crops, not just strawberries. Diego is teaching them to grow strawberries organically and to use drip irrigation. To encourage people to use these methods he has created his own demonstration plots. He has divided his grandparents’ strawberry field into three areas: one with his modern system, one with local varieties grown the old way on bare soil, with flood irrigation, and a third part with modern varieties grown the old way. The modern varieties do poorly when grown the way that Diego’s grandparents used. And Diego says the old way is too much work, mainly because of the weeding, irrigation, pests and diseases.

Ucuchi is an attractive village in the hills, with electricity, running water, a primary school and a small hospital. It is just off the main highway between Cochabamba and Santa Cruz, an hour from the city of Cochabamba where you can buy or sell almost anything. Partly because of these advantages, some young people are returning to Ucuchi. Organic strawberries are hard to grow, and rare in Bolivia. But a unique product, like organic strawberries, and inspired leadership can help to stem the flow of migration, while showing that there are ways for young people to start a viable business in the countryside. Diego clearly loves being back in his home village, stopping his pickup truck to chat with people passing by on the village lanes. He also brings his own family to the farm on weekends, where he has put a new tile roof on his grandparents’ old adobe farm house.

Agriculture is more than making a profit. It is also about family history, community, and finding work that is satisfying and creative.

Drip irrigation for tomato

EN EL FRUTILLAR DE NUEVO

Por Jeff Bentley, 15 de marzo del 2019

Como muchos bolivianos, Diego Ramírez nunca pensó en quedarse en la comunidad donde nació, y empezar un emprendimiento agrícola en las pequeñas chacras de su familia. Diego cuenta que de niño le encantaba recoger fruta en la pequeña parcela de frutillas de sus abuelos en la comunidad de Ucuchi, y nadar con sus amigos en una poza de riego, llena de agua de manantial, pero de joven tuvo que vivir en la ciudad pequeña de Sacaba para estudiar en colegio. Luego se fue a estudiar a la Universidad UMSS, la carrera de ingeniería de sistemas. Culminado los estudios, empezó a trabajar en la ciudad de Cochabamba.

Años más tarde, el padre de Diego llamó a sus siete hijos para decirles que estaba vendiendo el terreno de sus abuelos. Tenía sentido. Los abuelos habían fallecido, y nadie había trabajado la tierra durante unos 15 años. Sin embargo, a Diego le pareció una tragedia, así que dijo: “Yo la voy a trabajar”. Algunos pensaron que era un chiste. En Ucuchi, la gente estaba en plan de dejar la agricultura, no meterse en ella. Preferían emigrar al Oriente de Bolivia y muchos se habían ido del país. Por esta razón muchas de las parcelas están abandonadas. No es el tipo de lugar al que la gente como Diego normalmente regresa.

Cuando Diego decidió revivir su finca familiar ya hace dos años, buscó inspiración en el Internet. Aunque la frutilla es un cultivo ancestral de la comunidad de Ucuchi y muy rentable en Cochabamba, Diego se enteró de una empresa productora de frutillas en Santo Domingo, Santiago, en el vecino país de Chile, que daba consejos y vendía plantas. Santo Domingo está a 2450 km de Cochabamba, pero Diego se tomó tan en serio las frutillas que fue allí un fin de semana y trajo 500 plantas de frutillas. Crucialmente, también aprendió sobre el cultivo tecnificado de frutillas, aplicando el riego por goteo y plantado en camas tapadas con plástico. Movido por sus nuevos conocimientos, buscó distribuidores en Cochabamba que vendían equipos de riego por goteo y los instaló, junto con el mulch plástico, un método común en la producción moderna de fresas.

Diego se inclinó más en la producción agroecológica para producir frutillas, así que se contactó con la Fundación Agrecol Andes que estaba organizando una asociación de productores ecológicos en Sacaba, la pequeña ciudad donde Diego vive, a medio camino entre su terreno y la ciudad grande de Cochabamba. Diego ya tiene certificación de productor ecológico con SPG PAS (Sistema Participativo de Garantía Productores Agroecológicos Sacaba), Diego aprendió a hacer su propio biol (una solución fermentada de estiércol de vaca que fertiliza el suelo mientras añade microbios buenos). Ahora mezcla el biol en el tanque de riego por goteo, fertilizando las frutillas una gota a la vez.

Diego también hace sus propias soluciones orgánicas, como el sulfocálcico y el caldo bordelés. Fumiga estas preparaciones cada dos semanas para controlar el oídium, los thrips (un pequeño insecto), la arañuela roja, y la pudrición de cuello. Me impresionó. Mucha gente habla de aplicaciones orgánicos, pero pocos hacen las suyas. “No es tan difícil”, Diego dijo cuando le pregunté de dónde hallaba el tiempo.

Diego encuentra tiempo para hacer muchas cosas admirables. Tiene un talento natural para el marketing y ha diseñado sus propias cajas de cartón delgado, que ha hecho imprimir en La Paz. Sus clientes reciben la fruta en una bonita caja, en lugar de en una bolsa de plástico, donde la fruta se daña fácilmente. Vende directamente a los clientes que vienen a la misma parcela, en las ferias agroecológicas y en tiendas que comercializan productos ecológicos.

Diego todavía hace su trabajo normal en la ciudad, mientras que también tiene una cartera en la comunidad de Ucuchi. También cultiva una pequeña chacra de papas y está plantando árboles frutales y tunas en las laderas pedregosas arriba de su frutillar. Diego también ha iniciado una asociación de agricultores con sus vecinos, diez hombres y diez mujeres, incluidos adultos mayores y jóvenes que todavía están en la universidad.

Los miembros de la asociación cultivan diversos cultivos, no sólo frutillas. Diego les enseña a cultivar frutillas orgánicamente y a usar el riego por goteo. Para animar a la gente a usar estos métodos, ha creado sus propias parcelas de demostración. Ha dividido el frutillar de sus abuelos en tres áreas: una con su sistema moderno, tecnificado, otra con variedades locales cultivadas al estilo antiguo en suelo desnudo, con riego por inundación, y una tercera parte con variedades modernas cultivadas a la manera antigua. Las variedades modernas no rinden bien cuando se cultivan al estilo de los abuelos. Y Diego dice que la forma antigua es mucho trabajo, principalmente por el desmalezado, el riego y las enfermedades además de las plagas.

Ucuchi es una atractiva comunidad en las faldas del cerro, con electricidad, agua potable, una escuela primaria y un pequeño hospital. Está justo al lado de la carretera principal a Santa Cruz, a una hora de la ciudad de Cochabamba donde se puede comprar o vender casi cualquier cosa. En parte por estas ventajas, algunos jóvenes se están volviendo a la comunidad de Ucuchi. Las frutillas orgánicas son difíciles de cultivar, y son raras en Bolivia. Pero un producto único, como las frutillas orgánicas, y un liderazgo inspirado pueden ayudar a frenar el flujo de la migración, al mismo tiempo de mostrar que hay maneras viables para que los jóvenes empiecen con un emprendimiento personal en el campo. A Diego le encanta estar de vuelta en su comunidad: para su camioneta para charlar con la gente que pasa por los caminos del pueblo. También trae a su propia familia a la finca los fines de semana, donde ha puesto un nuevo techo de tejas en la vieja casa de adobe de sus abuelos.

La agricultura es más que la búsqueda de lucro. También se trata de la tradición familiar, la comunidad y de sentirse realizado con un trabajo satisfactorio y creativo.

A common ground March 8th, 2020 by

Farmers need new ideas, and researchers need data. When these two professional groups meet in the framework of collaborative or participatory research, it is often not clear who has to evolve in what direction: do farmers need to learn about research protocols, systematically collecting and analysing data, or do researchers need new ideas from farmers to guide their research agenda?

When grantees of the McKnight Foundation from West Africa recently met in Montpellier, France, at a Community of Practice (COP) meeting to share experiences, it was refreshing to see how this network has over time taken ownership of some key values on doing research with farmers on agroecology, as a way to move towards a more just and equitable food system with care for the people and the planet.

Out of the more than 60 people from farmer organisations, NGOs, research institutes and universities from Mali, Burkina Faso and Niger, I was glad to run into some old friends. Ali Maman Aminou is a farmer and director of the federation of farmer unions in Maradi (FUMA Gaskiya), one of the main farmer organisations in Niger.

In 2011, Aminou was one of the twelve people we trained during a 2-week intensive workshop on making quality farmer-to-farmer training videos. Ever since, Aminou has been using video in his interactions with the growing number of members, now some 18,000. The series of 10 videos on integrated striga and soil fertility management that were developed with ICRISAT and its partners were all translated into Hausa, which made it an ideal tool to trigger lively discussions with farming communities. Striga is a parasitic weed that attaches its roots to the roots of cereal crops, as such depriving the crop from the water and nutrients it needs.

“During one of the evenings that we showed the videos,” Aminou says, “one of the farmers spoke out and told he liked the videos, but that they had another technology to fight striga that was also efficient.” Aminou listened intently as the man went on to explain that farmers mix their millet seed with the powdery substance found around the seeds of the néré, a common tree across West Africa. When farmers sow millet, the néré powder apparently inhibits the striga seeds in the soil from germinating.

“This is amazing,” I told Aminou. “It would be great if you could turn this into a training video.” At that stage, it became apparent how much farmers and researchers had already begun to interact as equal players. Aminou swiftly turned to Salifou Nouhou Jangorzo, a lecturer from the University of Maradi in Niger, who had joined our discussion and said: “We need to find out more about this practice. We need all the details of how farmers do this.” Professor Salifou looked surprised at first; he had never heard of this practice before, but after 5 minutes of discussing with Aminou he was convinced. It turns out that he is planning a survey on a labour-saving weeding technology and so he decided on the spot that he would add some questions about managing striga with néré to his survey.

Farmer-to-farmer training videos, like the ones in the striga series, trigger farmers to experiment with new ideas. They also give farmers confidence to openly share their real-life experiences, knowledge and practices. Through a functional network these ideas can find their way back to researchers. In a progressive and collaborative research network, communication is not an end-product in itself, as Aminou has shown, but it feeds into a life of learning to make agriculture more resilient, profitable and responsive to farmers’ needs.

Finding a common ground between researchers and farmers does not happen overnight, it needs a concerted and long-term effort.

Note

The scientific name of the néré tree is Parkia biglobosa, also known as the African locust bean.

Un terrain d’entente

Les agriculteurs ont besoin de nouvelles idées et les chercheurs ont besoin de données. Lorsque ces deux groupes professionnels se rencontrent dans le cadre d’une recherche collaborative ou participative, il est souvent difficile de savoir qui doit évoluer dans quelle direction : les agriculteurs ont-ils besoin de connaître les protocoles de recherche, de collecter et d’analyser systématiquement les données, ou les chercheurs ont-ils besoin de nouvelles idées de la part des agriculteurs pour orienter leur programme de recherche ?

Lorsque les projets financés par la Fondation McKnight en Afrique de l’Ouest se sont récemment rencontrés à Montpellier, en France, lors de la réunion de comité de pratique (CoP) pour un échange d’expériences, il était intéressant de voir comment ce réseau s’est approprié, au fil du temps, certaines valeurs clés sur la recherche avec les agriculteurs en matière d’agroécologie comme moyen d’évoluer vers un système alimentaire plus juste et plus équitable, soucieux des populations et de la planète.

Sur plus de 60 personnes issues d’organisations de producteurs, d’ONG, d’instituts de recherche et d’universités du Mali, du Burkina Faso et du Niger, j’ai été heureux de rencontrer de vieux amis. Ali Maman Aminou est agriculteur et directeur de la fédération des unions de producteurs de Maradi (FUMA Gaskiya), l’une des principales organisations paysannes du Niger.

En 2011, Aminou était parmi les douze personnes que nous avons formées lors d’un atelier intensif de deux semaines sur la réalisation de vidéos de formation de qualité paysan à paysan. Depuis, Aminou utilise les vidéos dans ses interactions avec le nombre croissant de membres de l’organisation, qui s’élève aujourd’hui à environ 18 000 personnes. La série de 10 vidéos sur la gestion intégrée du striga et de la fertilité des sols, développée avec l’ICRISAT et ses partenaires, a été traduite en Haoussa, ce qui rend l’outil idéal pour susciter de vives discussions avec les communautés agricoles. Le striga est une mauvaise herbe parasite qui attache ses racines aux racines des cultures céréalières, privant ainsi la culture de l’eau et des nutriments dont elle a besoin.

“Lors d’une soirée où nous avons montré les vidéos”, raconte Aminou, “un des agriculteurs a pris la parole et a dit qu’il aimait les vidéos, mais qu’ils avaient une autre technologie pour lutter contre le striga qui était aussi efficace”. Aminou a écouté attentivement comment les agriculteurs mélangent leurs graines de millet avec la substance poudreuse qui se trouve autour des graines du néré, un arbre commun dans toute l’Afrique de l’Ouest. Lorsque les agriculteurs sèment du millet, la poudre de néré empêche apparemment la germination des graines de striga dans le sol.

“C’est incroyable”, ai-je dit à Aminou. “Ce serait génial si vous pouviez en faire une vidéo de formation.” À ce stade, il est apparu clairement que les agriculteurs et les chercheurs avaient déjà commencé à interagir en tant qu’acteurs égaux. Aminou s’était rapidement tourné vers Salifou Nouhou Jangorzo, un professeur de l’Université de Maradi au Niger, qui s’était joint à notre discussion et a déclaré “Nous devons en savoir plus sur cette pratique. Nous avons besoin de tous les détails sur la façon dont les agriculteurs font cela “. Le professeur Salifou a d’abord eu l’air surpris ; il n’avait jamais entendu parler de cette pratique auparavant, mais après 5 minutes de discussion avec Aminou, il était convaincu. Il s’avère qu’il prévoit d’effectuer une enquête sur une technologie de désherbage permettant d’économiser la main-d’œuvre et il a donc décidé sur-le-champ d’ajouter à son enquête quelques questions sur la gestion de la striga avec la poudre de néré.

Les vidéos de formation paysan à paysan, comme celles de la série sur le striga, incitent les agriculteurs à expérimenter de nouvelles idées. Elles donnent également aux agriculteurs la confiance nécessaire pour partager ouvertement leurs expériences, leurs connaissances et leurs pratiques réelles de la vie. Grâce à un réseau fonctionnel, ces idées peuvent être transmises aux chercheurs. Dans un réseau de recherche progressive et collaborative, la communication n’est pas un produit final en soi, comme l’a montré Aminou, mais elle alimente une vie d’apprentissage pour rendre l’agriculture plus résistante, plus rentable et plus sensible aux besoins des agriculteurs.

Trouver un terrain d’entente entre chercheurs et agriculteurs ne se fait pas du jour au lendemain, il faut un effort concerté et à long terme.

Le nom scientifique du néré est Parkia biglobosa, également connu sous le nom de caroubier Africain.

Poisoning our friends October 20th, 2019 by

Except for entomologists, no one knows more about insects than farmers. Wherever researchers have bothered to talk to smallholders about insects, whether in Honduras, Nepal, or among the Dogon of Mali, or the Kayapó of the Brazilian rainforest, we see that rural people know the names of hundreds of insects and spiders. This is especially true of critters that are conspicuous (such as the big ones that are active during the day) or those that make themselves important, e.g. by eating crops.  

However, a recent, quantitative global literature review by Kris Wyckhuys and colleagues confirms that farmers know little about beneficial insects, especially in industrialized countries. As we saw in this blog last week, it is fairly easy to notice toads and other relatively large animals eating insect pests. Many farmers know that birds, frogs and cats are natural enemies of pests. Yet Wyckhuys found that worldwide, farmers mention on average only 0.9 insects or spiders that help to control insect pests.

Farmers can have sophisticated knowledge of certain, individual insect species. For example, Paul Van Mele and colleagues have described Vietnamese farmers who used weaver ants to control pests in fruit orchards. Such cases are, however, disappointingly rare. Weaver ants are big, diurnal, and easy to spot in their treehouse nests sewn together from leaves. Farmers were also motivated to watch weaver ants because they prey on insects like fruit flies in high-value orchards.  Most other natural enemies of insect pests, “farmers’ friends” go unnoticed. Hardly any rural people know about other common natural enemies of pests, such as parasitic wasps, insect-eating fungi and nematodes.

Farmers tend to use more pesticides in cash crops, and know fewer natural enemies for these crops, than in food staples. The use of pesticides is growing worldwide, while the pest problems are as bad as ever. Farmers are born experimenters, but to find alternative to pesticides, they need to know more about the natural enemies of insect pests.

Wyckhuys suggests that some of the world’s half trillion-dollar subsidies for agriculture could be devoted to agro-ecological education. Farmers will never find alternatives to pesticides unless they understand that most insects are beneficial. As farmers use insecticides to kill pests, they unwittingly poison their friends, the insects that eat and kill those pests.

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.

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 solía pensar que los comités 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 podrían hacerse por sí 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 túnel en la tierra, lo esconde con granos de arena, encuentra una oruga grande y gorda, la paraliza y la arrastra hasta el túnel del nido, que la avispa milagrosamente logra encontrar, como si tuviera un GPS. Los videos muestran cómo la avispa descubre el nido, inserta al desafortunado gusano y pone un huevo en él. Luego, la cría 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 camarógrafo profesional que critique sus videos puede ser desalentador, pero Milton sin duda sintió que Marcella le daría una crítica positiva, con empatía. Su riesgo valió la pena. Colaboramos con Milton para escribir un guion para su vídeo. Marcella editó sus clips y los combinó en un video corto, que estamos orgullosos de lanzar esta semana.
