Silent Spring, better living through biology June 13th, 2021 by

Hey farmer, farmer

Put away that DDT now

Give me spots on my apples

But leave me the birds and the bees

Please!

“Big Yellow Taxi,” by Joni Mitchell

It’s possible that Joni Mitchell’s 1970 lyrics owe a debt to Rachel Carson’s (1962) book Silent Spring. Why not? The book was a major influence on the environmental movement, inspiring Earth Day, the Environmental Protection Agency (EPA), and the US ban on DDT, besides. Less often mentioned, the book also touched off integrated pest management (IPM).

For all that, Carson makes few mentions of farmers in her book. Many of the cases she meticulously described are of the US and Canadian governments arrogantly dropping insecticide from airplanes, blanketing forest, field, stream, pasture, and even suburban communities.

DDT and other noxious organophosphate insecticides were applied in each case to kill some specific pest: The Japanese beetle, the spruce budworm, and the fire ant, for example.

In every case, the results were disastrous. Dead livestock, and cancer in humans, but the birds were decimated. The bald eagle, national bird of the USA, was nearly exterminated by DDT. The bald eagle has since made a comeback, but many other bird species are on the decline.

The chemical companies that sold these pesticides to the government had the audacity (or the stupidity) to claim that insects would not be able to evolve resistance to the toxins. The pests would be eradicated!

But they weren’t. The bugs won the war. In every single case, the target pest species was more numerous a few years after the spraying started.

To explain this, Carson coined the analogy of the pesticide treadmill. Before a pesticide is used, an insect’s population is controlled by its natural enemies, such as spiders, wasps, ants, and birds. Insecticide kills the pest, and its natural enemies, too. The pest evolves resistance to the pesticide, much quicker than do its natural enemies (which often reproduce more slowly and absorb more of the poison). Once freed from its natural enemies, the pest population explodes. Now it has to be managed by pesticides.

In 1962, Carson mused that Darwin would have been pleased to see how well his theories were proven, as insect pests had quickly evolved resistance to pesticides. If Carson were here today, she might not be so happy to see how the chemical companies have also evolved. They have engineered maize and soy varieties that can withstand herbicides, so fields can be sprayed with glyphosate that kills all the plants, except for the ones with designer genes. The corporations that sell the seed conveniently sell the herbicide as well. Companies like Monsanto once claimed that the weeds would not be able to evolve resistance to the genetically modified crops.

But they did. At least 38 species of weeds are now resistant to glyphosate.

As Carson said nearly 60 years ago (and it’s still true), farms and forests are biological systems. Their pest problems have to be solved with biology, not with chemistry. In Rachel Carson’s day, only 2% of economic entomologists were working on biological pest control. Most of the other 98% were studying chemicals. Funding for chemicals breeds contempt for biological alternatives.

Biological pest control uses natural enemies to control pests. Carson cites the famous case of the cottony cushion scale, a citrus pest in California. The pest was controlled in 1872, long before DDT was available, by importing a lady bird beetle from Australia that ate the scale insects. The scale insects then became rare in California orchards until the 1940s, when insecticides killed the lady bird beetles and the pests exploded.

A recent book by Biovision and IPES Food suggests that many big donors still fund conventional research in pesticides. Perhaps it’s time to invest in scientists who can pick up Rachel Carson’s challenge, and solve biological problems with biology.

Zoom to Titicaca June 6th, 2021 by

Vea la versión en español a continuación

Covid may be the world’s most spectacular emerging disease, but agriculture has its own new pests and diseases. Fortunately, collaboration between agronomists and farmers can offer solutions, as I saw in a recent meeting on the shores of Lake Titicaca.

This is 2021, so we met on Zoom, but I was struck by how much the meeting resembled others I have attended in person with farmers and agronomists.

Ing. Sonia Laura, a researcher from Prosuco who works closely with farmers, had driven out to the village of Iquichachi, a couple of hours from La Paz. Sonia set up the call on her laptop, and the farmers (Sra. Cristina, Sra. Arminda, Sr. Juan, Sr. Paulino, Sr. Zenobio, and Sr. Fidel) all managed to squeeze onto the screen. Bundled up in coats and hats against the high Andean cold, they explained how several years ago, they noticed a new worm eating the potatoes they store at home.

The moth lays its eggs on stored potatoes, and on potato plants in the field. The eggs hatch into caterpillars that go back and forth: from field to home in the harvest, and from storage to field with the seed.

The farmers showed some graphs of data they had been collecting with Sonia, under advice from Ing. Reinaldo Quispe, an agronomist from Proinpa, who joined the call from his office in La Paz. Reinaldo and the farmers had been using the sex scent (pheromone) of female moths to attract and trap the male moths. Each moth species has its own unique sex pheromone. Reinaldo had identified the pests, two related species of tuber moths, native to the Andes, but usually found in the lower, warmer valleys. Both species belong to a moth family that specializes in infesting stored foods.

The agronomist Raúl Ccanto joined us from Peru, from the NGO Yanapai. Raúl explained that Peruvian farmers had suffered from these two moths for many years. Over the years of working with the farmers, Yanapai and others had developed some practical solutions.

As Raúl explained, select the seed carefully. When you take seed from the house to plant in the field, make sure that you only plant healthy tubers, not the ones full of worms.

Also rotate your crops. “This is something you farmers have always done, but it’s important to say that it is a good thing.” Growing potatoes one year, followed by other roots and tubers (such as oca and papalisa, which are not of the potato family), and then other legumes and cereals, helps to keep the soil free of potato pests.

Raúl’s PowerPoint included the results of experiments, done in collaboration with Peruvian farmers, where they tried various ways to manage the moths in stored seed potato. One idea that worked well, and was also cheap, was to dust healthy seed potatoes with talc, which keeps the moths from laying their eggs in potatoes. The talc worked almost as well as malathion, the insecticide.

Raúl skipped lightly over the malathion, barely mentioning it, and for good reason. He had included the chemical treatment in the experiment as a comparison, but he was not promoting it. As Reinaldo explained, farmers often prefer insecticides and use them even in stored potatoes, which one should not do.

In fact, medical schools in Bolivia teach their third-year students to diagnose and treat malathion poisoning, because it is common. “This is something you’ll see,” the older doctors tell their students.

With any new pest or disease, it’s important to know where it came from. Raúl explained that the moths may have recently colonized the cold Altiplano, not just because of climate change, but also because people are bringing wormy seed in from fairs in distant parts of the country. And they are growing more potatoes. As more of the land is planted more often and over larger areas, to meet market demand, a more attractive environment is created for potato pests.

Yes, the farmers agreed, potatoes are being grown more often. And that is why it is crucial for scientists and farmers to put their heads together, to confirm useful ideas, from different perspectives.

The farmers wanted to know if there was something they could apply to their potatoes, to kill the moth. Raúl and Reinaldo both explained that there is no one thing that will manage the pest. It will have to be managed by rotating crops, and by selecting healthy seed. Other ideas like dusting the potatoes with talc will also help. The good news is that the moths can be managed.

It may be in human nature to yearn for simple solutions. Many of us have simply wished that Covid would go away, and that things would go back to normal. Like Covid, managing the tuber moth will require several good ideas, well explained, widely shared and applied.

In this case, the new information motivated the farmers to set up their own experiments. Sonia told me that after our call, the farmers met to reflect and take action. They decided that each one of them would select their seed, clean their potato storeroom, and sprinkle talc on the selected seed. They will keep using the pheromone traps, among other things. Later, they will explain these practices to their other community members, to take action as a group.

Scientific names

The tuber moths are Phthorimaea operculella and Symmetrischema tangolias (Lepidoptea: Gelechiidae).

Oca (Oxalis tuberosa) and papalisa (Ullucus tuberosus) are native Andean crops, not widely grown outside the region. The papalisa is also called “olluco” in Peru.

Talc is a clay mineral, magnesium silicate, a natural stone that is ground to make a powder.

ZOOM AL TITICACA

Por Jeff Bentley, 6 de junio del 2021

El Covid-19 podría ser la enfermedad nueva más espectacular del mundo, pero la agricultura tiene sus propias plagas y enfermedades emergentes. Afortunadamente, la colaboración entre agrónomos y agricultores puede ofrecer soluciones, como vi en una reciente reunión a orillas del Lago Titicaca.

Estamos en el 2021, así que nos reunimos por Zoom, pero me sorprendió lo mucho que se parecía la reunión a otras a las que he asistido en persona con agricultores y agrónomos.

La Ing. Sonia Laura, una investigadora de Prosuco, que trabaja estrechamente con los agricultores, había ido en camioneta hasta la comunidad rural de Iquicachi, a un par de horas de La Paz. Sonia organizó la llamada en su laptop, y los agricultores (las y los señores Cristina, Arminda y Juan, Paulino, Zenobio, Fidel,) se hicieron entrar todos en la pantalla. Abrigados con chompas y gorros contra el frío altoandino, explicaron que hace pocos años se dieron cuenta de que un nuevo gusano se comía las papas que almacenaban en sus casas.

La polilla de papa pone sus huevos en las papas almacenadas y en las plantas de papas en el campo. De los huevos nacen gusanos del campo, que van a casa en la cosecha, y del almacén regresan a la chacra con la semilla.

Los agricultores mostraron algunos gráficos de datos que habían estado recopilando con Sonia, bajo la orientación del Ing. Reinaldo Quispe, de Proinpa, quien se unió a la llamada desde su oficina en La Paz. Sonia y los agricultores habían estado usando el olor sexual (feromona) de las polillas hembras para atraer y atrapar a las polillas macho. Cada especie de polilla tiene su propia feromona sexual. Reinaldo había identificado las plagas, dos especies relacionadas de polillas del tubérculo, nativas de los Andes, pero que suelen encontrarse en los valles más bajos y cálidos. Ambas especies pertenecen a una familia de polillas especializada en infestar alimentos almacenados.

Desde Perú nos acompañó el agrónomo Raúl Ccanto, de la ONG Yanapai. Raúl explicó que los agricultores peruanos habían sufrido estas dos polillas durante muchos años. A lo largo de sus años de trabajo con los agricultores, Yanapai y otros han desarrollado algunas soluciones prácticas.

Como explicó Raúl, hay que seleccionar la semilla con cuidado. Cuando saques la semilla de la casa para sembrarla, asegúrate de plantar sólo los tubérculos sanos, no los que están llenos de gusanos.

También hay que rotar los cultivos. “Esto es algo que ustedes los agricultores siempre han hecho, pero es importante decir que es bueno que lo hagan”. Lo que ayuda a mantener el suelo libre de plagas de la papa es cultivarlas solo un año, seguido de otras raíces y tubérculos (como la oca y la papalisa, que no son de la familia de la papa), y luego sembrar leguminosas y cereales.

La presentación de Raúl incluyó los resultados de los experimentos, realizados en colaboración con agricultores peruanos, en los que se probaron varias formas de controlar las polillas en los almacenes de semillas de papa. Una idea que funcionó bien, y que además era barata, fue rociar la papa seleccionada con talco, que impide que las polillas pongan sus huevos en las papas. El talco funcionaba casi tan bien como el malatión, el insecticida.

Raúl pasó por alto el malatión; apenas lo mencionó, y con razón. Había incluido el tratamiento químico en el experimento como comparación, pero no lo promovía. Como explicó Reinaldo, los agricultores suelen preferir los insecticidas y los usan incluso en las papas almacenadas, lo cual no se debe hacer.

De hecho, las facultades de medicina de Bolivia enseñan a sus estudiantes de tercer año a diagnosticar y tratar la intoxicación por malatión, porque es algo común. “Esto es algo que van a ver”, dicen los doctores a sus alumnos.

Con cualquier plaga o enfermedad nueva, es importante saber de dónde viene. Raúl explicó que las polillas pueden haber colonizado recientemente el frío Altiplano, no sólo por el cambio climático, sino también porque la gente está trayendo semillas agusanadas de ferias en otras partes del país. Y están cultivando más papas sobre mayor superficie. A medida que se siembra más seguido y en más área, para satisfacer la demanda del mercado, se crea un ambiente más atractivo para las plagas de la papa.

Sí, los agricultores reconocieron que hoy en día las papas se cultivan más seguido. Y por eso es crucial que científicos y agricultores compartan sus ideas, para confirmar las que son útiles.

Los agricultores querían saber si había algo que pudieran aplicar a sus papas para matar la polilla. Raúl y Reinaldo explicaron que no hay una sola cosa que la pueda manejar. Habrá que controlar la plaga mediante la rotación de cultivos y la buena selección de semillas. Otras ideas, como aplicar talco a las papas, también ayudarán. La buena noticia es que las polillas sí tienen solución.

Tal vez algo en la naturaleza humana anhela las soluciones sencillas. Muchos hemos deseado que el Covid desaparezca de una sola vez, y que las cosas vuelvan a la normalidad. Al igual que el Covid, el manejo de la polilla de la papa requerirá varias buenas ideas, bien explicadas, ampliamente compartidas y competentemente aplicadas.

En este caso, la nueva información motivó la gente a armar sus propios experimentos. Sonia me informa que se reunieron para reflexionar y tomar acuerdos. Decidieron que cada persona del grupo haría la selección de semilla. Limpiaría su almacén de papas, y pondría talco en las papas seleccionadas. Seguirán con las trampas con feromonas, entre otras cosas. Luego comunicarán estas prácticas en una reunión con toda la comunidad para tener un trabajo comunal en el control de esta plaga.

Nombres científicos

Las polillas de la papa son Phthorimaea operculella y Symmetrischema tangolias (Lepidoptea: Gelechiidae).

La oca (Oxalis tuberosa) y la papalisa (Ullucus tuberosus) son cultivos nativos andinos, poco cultivados fuera de la región. La papalisa también se llama “olluco” en el Perú.

El talco es silicato de magnesio. Es una piedra natural que se muele para obtener el polvo. Como explica Raúl Ccanto, es un “mineral no metálico”.

Commercial family farming Bolivian style May 30th, 2021 by

Vea la versión en español a continuación

In earlier blogs (Our threatened farmers, Damaging the soil and our health with chemical reductionism) Paul and I have written that farmers are Stuck in the middle between just a few large produce buyers and handful of seed and agrochemical companies. Farmers are forced to take any prices offered by their buyers, and by their suppliers as well. It’s a bind that forces many family farmers out of business.

It doesn’t have to be that way, as I was reminded recently on a stretch of the old highway from Santa Cruz, Bolivia to Cochabamba, at some 3000 meters above sea level. Ana and I noticed all the farmers gathering potatoes into large, blue sacks. They were getting ready for the weekly fair at “El Puente”, the bridge over the Lope Mendoza River.

Seeing the potato growers, I suddenly felt the urge to participate in this robust farmers’ market which has been self-sustaining for decades.

In a flat space in the canyon, every Monday hundreds of smallholder farmers bring fresh produce, mostly potatoes. El Puente is like a small town that leaps into existence with the Monday fair, only to be abandoned for the rest of the week.

This was Sunday. The shop fronts were closed, locks on heavy steel doors. By Monday morning they would be doing a brisk business in farm supplies. One temporary restaurant was open, with chicken roasting on a large charcoal grill, ready to feed the farmers who had arrived early, on Sunday afternoon.

We past an empty space that would soon be full of vendors who travel from fair to fair, selling the things that rural families like and need, soap and salt, cooking oil, tinned sardines, matches and clothing. Today it was still empty, but the potato pavilion was filling up. It’s just a concrete slab with a sheet metal roof and no walls. Farmers bring in their produce, in 100 kilo bags (called a carga), and wait for customers.

Some people come from the city on the bus on Monday to buy a carga to eat at home, or half a dozen of them, to sell. They rent space on a truck to deliver the potatoes to Cochabamba. The largest buyers may load a small truck with six or twelve tons to sell to retailers in the cities. In this lightly regulated market, potatoes may go through as few as four links, from farmer to small-time wholesaler, to retailer, to customer. Each one is a small, family business. It’s Adam Smith’s ideal of capitalism, with many willing buyers and many others eager to sell.

Ana soon met a farmer in early middle age, wearing a long skirt, with a scarf tied over her head.

We asked her for an arroba (25 pounds, or 11.4 kilos) of potatoes. “Take half a carga (50 kilos)” she said, so we did. After all, this was a wholesale market. The farmer led us to her wares, maybe a dozen bags. Each farmer was there with a cluster of potatoes in 100 kilo bags. Each cluster was carefully separated from the other by a space just big enough to squeeze through. The farmer wanted 90 Bolivianos ($13) for her fine, native potatoes, and she wouldn’t take less. She was a price giver, not a taker. We were soon on our way with our 50 kilos, from the epicenter of the Bolivian potato market.

After the Bolivian Revolution of 1952, the large farms (haciendas) were divided and given to the people who worked them. According to fake history, repeated sometimes even in schools, the Agrarian Reform of the Revolution failed because the land was split up into such small parcels that they were uneconomical to produce anything. It’s a racist lie. The Agrarian Reform succeeded, as we saw a few kilometers down the road.

An indigenous Andean farm family was standing next to 20 cargas of potatoes. Two tons of food going to market, neatly dressed in blue. The proud farmer reacted in the most contemporary fashion to his household’s accomplishment. Smart phone in hand, he walked across the highway and snapped a picture of his family and their harvest.

LA AGRICULTURA FAMILIAR TAMBIÉN PUEDE SER COMERCIAL

Por Jeff Bentley 30 de mayo del 2021

Antes, en este blog, Paul y yo hemos escrito que los países del norte, los agricultores están atrapados entre unos pocos grandes compradores de productos y un puñado de empresas de semillas y agroquímicos. Los agricultores se ven obligados a aceptar cualquier precio ofrecido por sus compradores, y también por sus proveedores. Es un aprieto que obliga a muchos agricultores familiares a abandonar su terreno.

No tiene por qué ser así, como volví a acordarme hace poco, manejando sobre la antigua carretera de Santa Cruz, Bolivia a Cochabamba, a unos 3.000 metros sobre el nivel del mar. Ana y yo nos fijamos en todos los agricultores que llenaban costales azules con papas. Se estaban alistando para la feria semanal en El Puente de Lope Mendoza.

Al ver a los productores de papas, sentí el impulso de participar en este robusto mercado agrícola, que se auto sostiene desde hace décadas.

En una parte plana en el cañón, cada lunes cientos de pequeños agricultores traen productos frescos, sobre todo papas. El Puente es como un pequeño pueblo que nace con la feria de los lunes, para quedar abandonado el resto de la semana.

Este día fue el domingo. Las fachadas de las tiendas estaban cerradas, con candados en las pesadas puertas de acero. El lunes por la mañana, los comercios de insumos agrícolas se llenarían de clientes. Un restaurante temporal atendía, con pollo asado en una gran parrilla de carbón, listo para alimentar a los agricultores que habían llegado temprano, el domingo por la tarde.

Pasamos por un espacio vacío que la mañana siguiente estaría lleno de vendedores que viajan de feria en feria, vendiendo antojos y artículos de primera necesidad, como jabón y sal, aceite de cocina, sardinas en lata, fósforos y ropa. Hoy todavía no había nadie, pero el pabellón de papas sí se estaba llenando. Es sólo una losa de hormigón con un techo de chapa y sin paredes. Los agricultores traen sus productos, en bolsas de 100 kilos (llamadas “cargas”), y esperan a sus clientes.

Algunas personas vienen desde la ciudad en el bus (el “micro”) el lunes para comprar una carga para comer en casa, o media docena de ellas, para vender. Alquilan espacio en un camión para llevar las papas a Cochabamba. Los que más compran pueden llegar un pequeño camión con seis o doce toneladas para venderlas a los minoristas de las ciudades. En este mercado poco regulado, las papas pueden pasar por apenas cuatro eslabones, desde el agricultor hasta el pequeño mayorista, la minorista y clientes. Cada uno de ellos es una pequeña empresa familiar. Es el ideal de capitalismo de Adam Smith, con mucha gente con ganas de comprar y vender.

Ana pronto conoció a una agricultora de mediana edad, con una falda larga y un pañuelo atado a la cabeza.

Le pedimos una arroba (25 libras, o 11,4 kilos) de papas. “Llévense media carga (50 kilos)”, nos dijo, y así lo hicimos. Al fin y al cabo, se trataba de un mercado mayorista. La agricultora nos condujo hasta sus mercancías, más o menos una docena de costales. Cada agricultor estaba allí con sus papas en sacos de 100 kilos. El producto de cada persona estaba cuidadosamente separado del otro por un espacio angosto donde uno apenas podía pasaba. La agricultora quería 90 bolivianos (13 dólares) por sus hermosas papas nativas, y no aceptaba menos. Ella estaba para dar un precio, no para recibirlo. Pronto nos pusimos en camino con nuestros 50 kilos, desde el epicentro del mercado boliviano de la patata.

Tras la Revolución Boliviana de 1952, las haciendas se dividieron y se repartían entre la gente que las trabajaba. Según la falsa historia, repetida a veces incluso en las escuelas, la Reforma Agraria fracasó porque la tierra se dividió en parcelas tan pequeñas (“surcofundias”) que no era rentable producir nada. Es una mentira racista. La Reforma Agraria tuvo éxito, como vimos unos kilómetros más adelante.

Una familia campesina estaba terminando de arreglar sus 20 cargas de papas. Dos toneladas de alimentos que iban al mercado, cuidadosamente vestidos de azul. El orgulloso agricultor reaccionó de la manera más contemporánea al logro. Teléfono inteligente en mano, cruzó la carretera y sacó una foto de su familia y su cosecha.

Teaching the farmers of tomorrow with videos May 23rd, 2021 by

Vea la versión en español a continuación

Youth around the world are leaving agriculture, but many would stay on the farm if they had appropriate technologies and better social services, as Professor Alejandro Bonifacio explained to me recently.

Dr. Bonifacio is from the rural Altiplano, the high plains of Bolivia. At 4,000 meters above sea level, it is some of the highest farmland in the world. Bonifacio has a PhD in plant breeding, and besides directing an agricultural research station in Viacha on the Altiplano, he teaches plant breeding part-time at the public university in La Paz (Universidad Mayor de San Andrés).

The university attracts many rural youths. Every year Bonifacio asks his new class of students to introduce themselves one-by-one and to tell where they come from, and to talk about their parents and their grandparents.

This year about 20% of the students in Bonifacio’s class are still living on the farm, and taking their classes online. Another 50% are the children or grandchildren of farmers, but are now living in the city. Many of these agronomy students would be more interested in taking over their parents’ farm, if not for a couple of problems.

One limitation is the lack of services in the rural areas: poor schools, bad roads, the lack of clinics, and no electricity or running water. While this is slowly improving, Covid has added a new twist, locking young people out of many of the places they liked to go to, and not just bars and restaurants. One advantage of city life is having access to medical attention, but this past year the students said it was as though the cities had no hospitals, because they were full of Covid patients. Classes were all on-line, and so the countryside began to look like a nicer place to live than the city. Many students went home to their rural communities, where there was much more freedom of movement than in the city.

Dr. Bonifacio told me that even when the youth do go home, they don’t want to farm exactly like their parents did. The youngsters don’t go in for all the backbreaking work with picks and shovels, but there is a lack of appropriate technology oriented towards young, family farmers, such as small, affordable machinery. Young farmers are also interested in exploiting emerging markets for differentiated produce, such as food that is free of pesticides. Organic agriculture also helps to save on production costs, as long as farmers have practical alternatives to agrochemicals.

Fortunately, there are videos on appropriate technologies, and Professor Bonifacio shows them in class. Today’s youth have grown up with videos, and find them convincing. Every year, Bonifacio organizes a forum for about 50 students on plant breeding and crop disease. He assigns the students three videos to watch, to discuss later in the forum. One of his favorites is Growing lupin without disease, which shows some organic methods for keeping the crop healthy. Bonifacio encourages the students to watch the video in Spanish, and Quechua or Aymara. Many of the students speak Quechua or Aymara, or both, besides Spanish. Some feel that they are forgetting their native language. “The videos help the students to learn technical terms, like the names of plant diseases, in their native languages,” Bonifacio says.

During the Covid lockdown, Prof. Bonifacio moved his forum online and sent the students links to the videos. In the forum, some of the students said that while they were home they could identify the symptoms of lupine disease, thanks to the video.

Bonifacio logs onto Access Agriculture from time to time to see which new videos have been posted in Spanish, to select some to show to his students, so they can get some of the information they need to become the farmers of tomorrow.

Kids who grow up on small farms often go to university as a bridge to getting a decent job in the city. But others study agriculture, and would return to farming, if they had appropriate technology for family farming, and services like electricity and high-speed internet.

ENSEÑAR A LOS AGRICULTORES DEL MAÑANA CON VIDEOS

Por Jeff Bentley, 23 de mayo del 2021

Por todas partes del mundo, los jóvenes abandonan la agricultura, pero muchos seguirían cultivando si tuvieran tecnologías apropiadas y mejores servicios sociales, como me explicó recientemente el docente Alejandro Bonifacio.

El Dr. Bonifacio es originario del Altiplano de Bolivia. A 4.000 metros sobre el nivel del mar, es una de las tierras agrícolas más altas del mundo. Bonifacio tiene un doctorado en fitomejoramiento y, además de ser jefe de una estación de investigación agrícola en Viacha, en el Altiplano, enseña fitomeoramiento a tiempo parcial en la universidad pública de La Paz (Universidad Mayor de San Andrés).

La universidad atrae a muchos jóvenes rurales. Cada año, Bonifacio pide a su nueva clase de estudiantes que se presenten uno por uno y digan de dónde vienen, y que hablen de sus padres y sus abuelos.

Este año, alrededor del 20% de los estudiantes de la clase de Bonifacio siguen viviendo en el área rural, desde donde se conectan a las clases virtuales. Otro 50% son hijos o nietos de agricultores, pero ahora viven en la ciudad. Muchos de estos estudiantes de agronomía estarían más interesados en trabajar el terreno sus padres, si no fuera por un par de problemas.

Una limitación es la falta de servicios en las zonas rurales: colegios deficientes, carreteras en mal estado, la falta de clínicas, luz y agua potable. Aunque esto está mejorando poco a poco, Covid ha introducido cambios, porque los jóvenes ya no pueden ir a muchos de los lugares que les gustaban, y no sólo las discotecas y los restaurantes. Una de las ventajas de la vida urbana es tener acceso a la atención médica, pero este último año los estudiantes dijeron que era como si las ciudades no tuvieran hospitales, porque estaban llenos de pacientes de Covid. Las clases eran todas en línea, por lo que el campo empezó a parecer un lugar más agradable para vivir que la ciudad. Muchos estudiantes se fueron a sus comunidades rurales, donde había más libertad de movimiento que en la ciudad.

El Dr. Bonifacio me dijo que, incluso cuando los jóvenes vuelven a casa, no quieren trabajar la tierra tal como lo hacían sus padres. Los jóvenes no se dedican al trabajo agotador con palas y picotas, pero hace falta la tecnología adecuada orientada a los jóvenes agricultores familiares, por ejemplo, la maquinaria pequeña y asequible. Los jóvenes agricultores también quieren explotar los mercados emergentes de productos diferenciados, como los alimentos libres de plaguicidas. La agricultura orgánica también ayuda a ahorrar costes de producción, siempre que los agricultores tengan alternativas prácticas a los productos agroquímicos.

Afortunadamente, existen videos sobre tecnologías adecuadas, y el Dr. Bonifacio los muestra en clase. Los jóvenes de hoy conocen los videos desde su infancia, y los encuentran convincentes. Cada año, Bonifacio organiza un foro para unos 50 estudiantes sobre el fitomejoramiento y las enfermedades. Asigna a los alumnos tres videos para que los vean y los discutan después en el foro. Uno de sus favoritos es Producir tarwi sin enfermedad, que muestra algunos métodos orgánicos para mantener el lupino sano. Bonifacio anima a los estudiantes a ver el video en español y en quechua o aymara. Muchos de los estudiantes hablan quechua o aymara, o ambos, además del castellano. Algunos sienten que están olvidando su lengua materna. “Los videos ayudan a los alumnos a aprender términos técnicos, como los nombres de las enfermedades de las plantas, en sus idiomas nativos”, dice Bonifacio.

Durante la cuarentena de Covid, el Dr. Bonifacio trasladó su foro a Internet y envió a los estudiantes enlaces a los videos. En el foro, algunos de los estudiantes dijeron que mientras estaban en casa podían identificar los síntomas de la enfermedad del tarwi (lupino), gracias al video.

Bonifacio entra en la página web de Access Agriculture de vez en cuando para ver qué nuevos videos se han publicado en español, para seleccionar algunos y enseñárselos a sus alumnos, para que aprendan algo de la información que necesitan para ser los agricultores del futuro.

Los hijos de agricultores suelen usar a la universidad como puente para conseguir un buen trabajo en la ciudad. Pero otros estudian agronomía, y volverían al agro, si tuvieran tecnología apropiada para la agricultura familiar, y servicios como electricidad e Internet de alta velocidad.

Iron for organic pigs May 16th, 2021 by

Organic agriculture is on the rise, but as the sector grows and more farmers convert from conventional to organic farming, regulations are continuously fine-tuned. Finding a balance between animal welfare and the heavy debt burden many conventional farmers have due to past investments in modern pig houses is a delicate exercise, as I recently learned from my friend, Johan Hons, a long-time organic farmer in north-eastern Belgium.

“When some 40 years ago a neighbour farmer offered to let me use one of his vacant stables, I bought my first Piétrain pigs (a Belgian breed of pig) and started rearing. In those early years, I always supplemented iron. A few years later, Vera and I were able to start our own farm. We were convinced that organic farming was the only way food should be produced, so I gave my pigs the space to roam around in the field. Ever since then, they never needed any iron injections and they never got sick,” Johan says.

Iron is an essential mineral for all livestock, especially for piglets. Iron-deficient piglets will suffer from anaemia: they will remain pale, stunted, have chronic diarrhoea and if left untreated they will die. Worldwide, piglets are commonly injected with a 200 milligram dose of iron a few days after birth. Although this intramuscular injection is effective against anaemia, it is very stressful to the piglets.

In a natural environment a sow acquires enough iron from the soil during rooting behaviour, which she passes on to the suckling piglets through her milk. But most pigs in conventional farming in Belgium are raised on slatted floors and have no access to soil. Sows only have enough iron reserves for their first litter. Piglets of the second and third litter would already have a shortage of iron and become sick, unless given supplements.

Under Belgian regulations, organic meat pigs are allowed only one medical treatment for whatever illness. If a second treatment is given, pigs can only be sold in the conventional circuit and hence farmers do not get a premium price. With more conventional farmers eager to convert to organic to earn a higher income, members of Bioforum, the Belgian multi-stakeholder platform for organic agriculture, requested the regulatory authorities whether iron injections could be considered as a non-medical treatment.

As a member of Bioforum, Johan suggested an alternative: “When the sow delivers in the sty, I daily give her piglets a few handfuls of soil from the moment they are one week old. I put it out of reach of the sow, otherwise she would eat it, and continue doing so until the piglets are a few weeks old and allowed outside. Just like human babies, the piglets have a curious nature and by giving them early access to soil, they immediately build up their iron stores and immunity.”

For Johan caring for animals is knowing what they need and providing them with all the comfort throughout their life. This starts at birth-giving.

However, his suggestion initially got a cold reception at the forum, whose members also includes retailers. Most farmers who want to convert to organic do not have the possibility of letting their pigs roam on the land, showing the dire realities of conventional farms in Belgium, where concrete is more abundant around the pig houses than soil.

And however creative they found Johan’s suggestion to provide piglets with soil in the stables, this was not considered a feasible option. Conventional farmers have invested heavily in modern pig houses with slatted floors and automated manure removal systems and bringing in soil would obstruct the system. Adjusting such houses to cater for organic farming is an expense few farmers are willing to make.

Belgian authorities decided that, because of lack of commercial alternatives to iron injections, they would be temporarily accepted in organic agriculture, on the condition that the iron formulation is not mixed with antibiotics.

A sustainable food system is at the heart of the European Green Deal. As the European Commission has set a target under its farm to fork strategy to have 25% of the land under organic agriculture by 2030, it will need to reflect on how far the regulations for organic agriculture can be stretched, as well as on possible measures to support farmers to convert.

If left to the pigs to decide, they would surely opt for more time outdoors and less concrete around their houses, not a tweak in the regulations to declassify iron injection as a medical treatment.
