Old know-how, early warning November 22nd, 2020 by

Vea la versi√≥n en espa√Īol a continuaci√≥n

In the Bolivian Andes, some officials are starting using local knowledge to improve their early warning systems for natural disasters.

For centuries, local farmers have used the signs of nature (clouds, stars, the behavior of plants and animals) to predict disasters like hail, floods and droughts, and to forecast the welcome rains that make crops grow.

Then, starting in 2004, Prosuco (a Bolivian organization) began to organize farmers with an interest in weather and organic farming. These expert farmers, called Yapuchiris, were encouraged to teach other farmers.

In southwest Bolivia, high on the Altiplano, the local government and the Technical University in Oruro are collaborating with some of these organized Yapuchiris to provide early warning, as Professor Gunnar Guzm√°n explained in a recent webinar. As he put it: the Yapuchiris, using local knowledge of nature, are excellent at making long-term predictions, three to four months in advance. Meteorologists cannot make such predictions, although they are quite accurate at about 4 days in the future.

Olson Paravicini of the Risk Management Unit of the government of Oruro added that the Yapuchiris’ knowledge is local, so that each one forecasts the weather for his or her own community. This matters in a place as big as Oruro. At 53,558 square kilometers, Oruro is about the size of New York state, bigger than the Netherlands. To apply local knowledge of weather over such a large area, Paravicini and colleagues are collaborating with groups of Yapuchiris, gathering their predictions to compile a departmental level forecast to provide early warnings of floods and other nasty weather.

One of the Yapuchiris, Bernabé Choquetopa, also had a slot on the webinar, explaining several of the signs he looks for. For example, when the leque leque (Andean lapwing) migrates back into Oruro in September, don Bernabé looks at its wing. If the patch on the bird’s wing is green, the rains will be good. Green eggs also mean good rain, and dark eggs mean drought. The signs reinforce each other, so after explaining that the ayrampu cactus was bearing lots of fruit and that the foxes had healthy coats, don Bernabé predicted that this would be a good, normal year for rains in his part of Oruro.

Professional weather observers are now paying attention to the Yapuchiris, who are increasingly organized and well respected. Guzm√°n thinks that some of the local signs of nature are 90% accurate, a probability that increases as several are used together.

Plants and animals that have evolved in a harsh landscape may have behaviors that reflect the coming weather. Observant local people have the wisdom to pay attention to the local patterns of life. I’m optimistic when I see local scientists who have respect for this knowledge. That alone is a good sign for the future.

SABERES ANTIGUOS, ALERTA TEMPRANA

Por Jeff Bentley, 22 de noviembre del 2020

En los Andes bolivianos, algunas autoridades han empezado a usar los conocimientos locales para mejorar sus sistemas de alerta temprana de desastres naturales.

Durante siglos, los agricultores locales han leído los signos de la naturaleza (las nubes, las estrellas, el comportamiento de las plantas y los animales) para predecir desastres como la granizada, las riadas y las sequías, y para pronosticar las queridas lluvias que nutren a los cultivos.

Luego, a partir de 2004, Prosuco (una organizaci√≥n boliviana) comenz√≥ a organizar a los agricultores interesados en el clima y la agricultura org√°nica. Se les alent√≥ a estos agricultores expertos, llamados Yapuchiris, a que ense√Īaran a los dem√°s.

En el Altiplano del sudoeste de Bolivia, el gobierno local y la Universidad T√©cnica de Oruro est√°n colaborando con algunos de estos Yapuchiris organizados para dar una alerta temprana, como explic√≥ el Ingeniero Gunnar Guzm√°n hace poco en un webinar. Seg√ļn √©l, los Yapuchiris, con su conocimiento local de la naturaleza, hacen acertadas predicciones a largo plazo, con tres o cuatro meses de anticipaci√≥n. A cambio, los meteor√≥logos no pueden hacer eso, aunque hacen buenos pron√≥sticos a unos 4 d√≠as en el futuro.

Olson Paravicini, de la Unidad de Gesti√≥n de Riesgos del Gobierno Aut√≥nomo Departamental de Oruro, a√Īadi√≥ que el conocimiento de los Yapuchiris es local, de modo que cada uno pronostica el tiempo para su propia comunidad. Esto es importante en un lugar tan grande como Oruro. Con 53.558 kil√≥metros cuadrados, Oruro es el tama√Īo del Costa Rica, m√°s grande que los Pa√≠ses Bajos. Para aplicar el conocimiento local del tiempo en una zona tan grande, Paravicini y sus colegas est√°n colaborando con grupos de Yapuchiris, aprendiendo sus pron√≥sticos para compilar un sistema de alerta temprana a nivel departamental para predecir riadas y otros desastres clim√°ticos.

Uno de los Yapuchiris, Bernab√© Choquetopa, tambi√©n habl√≥ en el webinar, explicando varias de los indicadores que √©l busca. Por ejemplo, cuando el leque rebinar vuelve a Oruro en septiembre, don Bernab√© mira su ala. Si es verduzca, las lluvias ser√°n buenas. Los huevos verdes tambi√©n significan buena lluvia, pero los huevos oscuros significan sequ√≠a. Los signos se refuerzan mutuamente, as√≠ que despu√©s de explicar que el cactus ayrampu estaban cargados de frutos y que los zorros ten√≠an buen pelaje, don Bernab√© predijo que este a√Īo ser√≠a bueno y normal para las lluvias en su sector de Oruro.

Ahora algunos meteorólogos profesionales prestan atención a los Yapuchiris, que son cada vez más organizados y respetados. Guzmán cree que algunos de los signos locales de la naturaleza tienen una precisión del 90%, probabilidad que aumenta a medida que se usan varios indicadores juntos.

Las plantas y los animales que han evolucionado en una tierra inh√≥spita pueden tener comportamientos que reflejan el tiempo y el clima. La gente local tiene la sabidur√≠a de observar cuidadosamente a los patrones locales de vida. Soy optimista cuando veo que los cient√≠ficos locales ganan respeto por este conocimiento. Eso s√≠ es una buena se√Īal para el futuro.

Reviving soils November 8th, 2020 by

Globally an estimated 20 to 60 million hectares of land in developing countries are acquired by foreign companies and investors. This so-called ‚Äúland grabbing‚ÄĚ has taken place for various reasons. The most obvious one is the hunger for maximising profit. The devastating effects on deforestation for the expansion of biofuels, sugar cane, palm oil and soya bean for animal feed are well known. A less visible reason is to secure food by those who have seen large areas of land in their home country become unsuitable for farming. This is particularly the case for India and China, where the Green Revolution model of industrial farming has been promoted for decades. Today, due to this industrial model of farming about a third of China‚Äôs total cultivated area is seriously eroded by wind and water. According to Dave Montgomery in his book Growing a Revolution, half of the soil carbon in the midwestern USA has been lost. At EU level, soil erosion affects over 12 million hectares of land ‚Äď about 7.2% of the total agricultural land ‚Äď and leads to ‚ā¨1.25 billion loss in crop productivity.

As people have seen the soil as a warehouse full of chemical elements that could be replenished at will to feed crops, they ignored the microorganisms that help plants to take up the nutrients in organic matter, and soil minerals. Microorganisms do not have chlorophyll to do photosynthesis, like plants do, and require organic matter to feed on.

While acquiring land in other countries as a strategy to secure domestic food supplies has created its own problems, it is hopeful to see that more sustainable initiatives triggered by civil society are gaining momentum, and receiving support from their governments. President Xi Jinping recently announced on television that China wants to stop destroying natural resources and instead become a global leader for green technologies. Through his speech he formalised the rising aspirations of Chinese civil society for healthy food.

For several years, the central government in India has strongly advocated ‚Äúzero budget natural farming,‚ÄĚ a form of regenerative agriculture that restores the health of soils without external inputs. By ending the reliance on purchased inputs and loans for farming, natural farming also aims to solve extreme indebtedness and suicides among Indian farmers. Many Indian states have adopted policies that support various forms of agroecology.

When one of our Indian partners produced a farmer training video on how soils can be revived with good microbes, a traditional practice that is now being widely promoted, I thought this would be helpful for our garden as well. When we moved into our house in north-eastern Belgium, some of the land had been under intensive cultivation for decades. The soil was hard and dead. Even though I had mixed some cow manure into the planting pits before planting my fruit trees 4 years ago, they have struggled during summers that seem to have become dryer and hotter year after year.

I watched the good microbes video from the Access Agriculture video platform and downloaded the factsheet. All I needed was fresh cow dung, cow urine, molasses and chickpea flour. But we don’t have cows, only a few sheep, and to have cow dung loaded with good microbes one would have to approach an organic farmer. So, I decided to collect fresh dung from our sheep and give it a try.

Jeff wrote in an earlier blog that farmers and farmer trainers in Bolivia mix dung with their hands without any reservations. Likewise, I have often witnessed during my interactions with farmers in South Asia how respectful they treat dung, as if it were gold. Hence, I started to mix the ingredients. The days before setting up my experiment I had collected my own urine, and because I didn’t have molasses to feed the good microbes I settleed for what we had in the house, brown sugar.

Farmers in India also mix leaves of the neem tree into the solution to help control insect pests and diseases. I replaced neem with a strong-smelling medicinal plant that we have in our garden, called ‚Äúboerenwormkruid‚ÄĚ. After having added all in 10 litres of water, I placed the drum in the shade, as good microbes don‚Äôt like direct sunlight.

For 10 days, I let the mixture ferment to increase the number of good microbes, stirring it twice a day to release the gases that could inhibit fermentation. The sweet-sour smell was a good indication that fermentation was successful. The result was a home-made variation of commercially available effective microorganisms, and an Indian recipe adapted to Belgian conditions. I kept the filtered solution in recycled plastic milk bottles. Every 2-3 weeks I mixed one of the bottles into 100 litres of water to then pour the solution around my 30 something fruit trees with a watering can, each tree receiving just enough to moisten the mulch around their base.

Seeing is believing. And doing it yourself adds conviction. In just 6 months the soil around our fruit trees has become black, soft and crumbly, keeping rainwater much better. I am confident that the humus and rich soil life will help the trees cope much better with the changing climate.

While we have destroyed much of our farm land for decades, the solutions to revive our soils are available. Green technologies spread faster when there is political goodwill and when farmers have the opportunity to learn from their peers, across borders. That is what Access Agriculture tries to achieve through its rich video library.

Boerenwormkruid is Tanacetum vulgare. The English common name is tansy.

Validating local knowledge July 26th, 2020 by

Vea la versi√≥n en espa√Īol a continuaci√≥n

Paul and I have written earlier stories in this blog about the yapuchiris, expert farmer-researcher-extensionists on the semi-arid, high plains of Bolivia. At 4000 meters above sea level (over 13,000 feet), seasoned farmers know how to observe plants and animals, clouds and stars, to predict the weather, especially to answer the Big Question on their minds: when will the rains start, so I can plant my crop?

All of the yapuchiris know some traditional ways of predicting the weather. Some yapuchiris also write their observations on a special chart they have designed with their agronomist colleagues at Prosuco, an organization in La Paz. The chart, called a Pachagrama, allows the yapuchiris to record the weather each day of the year, just by penciling in a few dots, so they can see if their predictions come true, and how the rains, frosts and hail affect their crops.

It can be daunting to prove the value of local knowledge, but it is worth trying.

Eleodoro Baldivieso is an agronomist with Prosuco, which has spent much of the past year studying the results of the Pachagrama weather-tracking charts. As he explained to me recently, Prosuco took four complete Pachagramas (each one filled out over seven years) containing 42 cases; each case is a field observed over a single season by one of the yapuchiris. Comparing the predicted weather with the recorded weather allowed Prosuco to see if the Pachagramas had helped to manage risk, mainly by planting a couple of weeks early, on time, or two weeks late.

Frost, hail and unpredictable rainfall are the three main weather risks to the potato and quinoa crops on the Altiplano. In October, a little rain falls, hopefully enough to plant a crop, followed by more rain in the following months. Average annual rainfall is only 800 mm (about 30 inches) in the northern Altiplano, and a dry year can destroy the crop.

For the 42 cases the study compared the yapuchiri’s judgement on the harvest (poor, regular, or good) with extreme weather events (like frost), and the planting date (early, middle or late) to see if variations in the planting date (based on weather predictions) helped to avoid losses and bring in a harvest.

The study found that crops planted two weeks apart can suffer damage at different growth stages of the plant. For example, problems with rainfall are especially risky soon after potatoes are planted, affecting crops planted early and mid-season. Frost is more of a risk for early potatoes at the start of the season, and for late potatoes when they are flowering. Hail is devastating when it falls as the mid and late planted potatoes are flowering.

The yapuchiris are often able to accurately predict frost, hail, and rainfall patterns months in advance. Scientific meteorology does a good job predicting such weather a few days away, but not several months in advance. When you plant your potatoes, modern forecasts cannot tell you what the weather will be like when the crop is flowering. Forecasting the weather in a challenging environment is helpful, at least some of the time. Planting two weeks early or two weeks late may help farmers take best advantage of the rain, but then expose the crop to frost or hail. Changing the planting dates can help farmers avoid one risk, but not another.

The weather is so complicated that risk can never be completely managed. And because scientific meteorology cannot predict hail and frost months in advance, local knowledge fills a void that science may never replace.

VALIDANDO LOS CONOCIMIENTOS LOCALES

Por Jeff Bentley

26 de julio del 2020

Paul y yo hemos escrito historias anteriores en este blog sobre los Yapuchiris, expertos agricultores-investigadores y extensionistas en el Altiplano semi√°rido boliviano. A los 4000 metros sobre el nivel del mar, los agricultores experimentados saben c√≥mo observar plantas y animales, nubes y estrellas para predecir el clima, especialmente para responder a la Gran Pregunta en sus mentes ¬Ņcu√°ndo comenzar√°n las lluvias para yo pueda sembrar mi chacra?

Todos los Yapuchiris conocen algunas formas tradicionales de predecir el tiempo. Algunos Yapuchiris tambi√©n apuntan sus observaciones en un cuadro especial que han dise√Īado con sus colegas, los ingenieros agr√≥nomos de Prosuco, una organizaci√≥n en La Paz. El cuadro, llamado Pachagrama, permite a los Yapuchiris registrar el tiempo cada d√≠a del a√Īo, con s√≥lo dibujar algunos puntos, para que puedan ver si sus predicciones se hagan realidad y como las lluvias, heladas y granizadas afectan sus cultivos.

Puede ser difícil comprobar ese conocimiento local, pero vale la pena intentarlo.

El Ing. Eleodoro Baldivieso, de Prosuco, ha pasado gran parte del a√Īo pasado estudiando los resultados de los Pachagramas. C√≥mo √©l me explic√≥ hace poco, Prosuco tom√≥ cuatro Pachagramas completos (de siete campa√Īas agr√≠colas) y 42 casos; cada caso es una parcela observada durante una campa√Īa por uno de los yapuchiris. El comparar el tiempo previsto con el tiempo registrado permiti√≥ a Prosuco ver si los Pachagramas hab√≠an ayudado a manejar el riesgo, principalmente mediante la siembra temprana (dos semanas antes), intermedia y tard√≠a (dos semanas despu√©s).

Las heladas, el granizo y la lluvia impredecible son los tres principales riesgos meteorol√≥gicos para los cultivos de papa y quinua en el Altiplano. En octubre cae un poco de lluvia, con la esperanza de que sea suficiente para sembrar un cultivo, seguida hasta marzo por m√°s lluvia. La precipitaci√≥n media anual es s√≥lo 800 mm en el Altiplano Norte, y un a√Īo seco puede destruir la cosecha, lo mismo que un a√Īo con mucha lluvia.

Para los 42 casos el estudio comparó la evaluación del Yapchiri de la cosecha (malo, regular, o bueno) con eventos extremos de tiempo (como heladas), con las fechas de siembra (temprano, mediano, o tarde) para ver si el variar la fecha de siembra (basado en el pronóstico del Yapuchiri) ayudó a evitar pérdidas y lograr una cosecha.

El estudio hall√≥ que los cultivos sembrados a dos semanas de diferencia pueden sufrir da√Īo en diferentes etapas de crecimiento da las plantas. Por ejemplo, los problemas con las lluvias son especialmente arriesgados poco despu√©s de la siembra de la papa, afectando m√°s a la siembra tempran, a principios y mediados de la temporada. Las heladas son m√°s riesgosas para las papas tempranas al comienzo de la temporada, y para las papas tard√≠as justo en la √©poca de floraci√≥n. El granizo es devastador para las siembras intermedias y tard√≠as, si la papa est√° en flor.

Los Yapuchiris a menudo son capaces de predecir con certeza las heladas, el granizo y los patrones de lluvia, con meses de antelaci√≥n. La meteorolog√≠a cient√≠fica a menudo puede predecir ese tiempo a unos pocos d√≠as, pero con meses de anticipaci√≥n. Cuando siembras tu papa, el pron√≥stico moderno no te puede decir c√≥mo ser√° el tiempo cuando tu cultivo est√° en flor. Pronosticar el tiempo en un entorno desafiante es √ļtil, al menos parte del tiempo. Sembrar dos semanas antes o dos semanas despu√©s puede ayudar a los agricultores a aprovechar mejor la lluvia, pero se expone el cultivo a las heladas o granizo, cuando es m√°s vulnerable. Cambiar las fechas de siembra puede ayudar a los agricultores a evitar uno de los riesgos, pero no siempre a todos.

El clima es tan complicado que el riesgo nunca puede ser manejado completamente. Y debido a que la meteorología científica no puede predecir el granizo y las heladas con meses de anticipación, el conocimiento local llena un vacío que la ciencia tal vez nunca reemplace.

Keep your cows in the family October 27th, 2019 by

In the 1980s, the Portuguese farmers I lived with kept two or three cows per household. Instead of hosing down the barns‚ÄĒthe greatest use of water on dairy farms‚ÄĒthe cows were stabled in a large room on the ground floor of the farm house. Every couple of days, farmers would lay down a clean bed of gorse, fern, heather and other wild plants. Instead of creating toxic lagoons of manure, the families would dig the manure out of the barns and spread it on their fields as organic fertilizer.

The parish of Pedralva, near Braga, Portugal, had four milking parlors. Twice a day the farmers (almost all women) would walk their cows down the lane to the milking parlor, where the operator, also a young woman, would milk the cows mechanically, record the amount of milk (clearly visible in a large, glass jar) and pipe the milk into a cold storage tank, to be picked up later by the dairy.

The milking parlor became a place where the farmers would chat and exchange ideas as they stood in line with their cows. I realize now that it was also a chance for the cows to get out of the house and take a stroll. The cows were not pets, but they all had names, enough to eat and drink, and they were never caged. The cows were usually fed on leftover maize stalks and pasture grass, although a handful of farmers with a dozen cows were starting to make silage. So, most of the feed was a byproduct of food production, rather than a diversion of human food to livestock.

The documentary film ‚ÄúCowspiracy,‚ÄĚ by Kip Anderson and Keegan Kuhn, tells of the complacency of Greenpeace, the Sierra Club, Surfrider Foundation, Rainforest Action Network, and Oceana: large, environmental organizations that ignore animal farming as a leading cause of climate change. Livestock account for 51% of global greenhouse emissions, while the whole transportation sector makes up just 13%. Cows make greenhouse gas as they fart out methane while the tractors and fertilizer factories all burn fossil fuel.

Livestock in the USA produce 30 times more feces than people. Fecal slurry from cows and pigs is kept in ‚Äúlagoons‚ÄĚ that often leak into rivers. In tropical countries forests are cleared to make pastures. Much of the forest burned in Bolivia this year was being cleared to graze cows for beef exports to China.

In Eat for the Planet, journalists Nil Zacharias and Gene Stone raise similar concerns, especially about the use of water. In the USA it takes 2000 liters of water to make a liter of milk, 15,000 liters of water to produce a kilo of meat. More corn, soybeans and wheat is produced to feed animals than humans, requiring vast amounts of water, energy and land.

Add this all together and it makes sense that the livestock sector is responsible for 51% of human-caused greenhouse gases.

Food and Animal Welfare, a recent book by Henry Buller and Emma Roe, raises concerns about the cruelty inflicted on the animals themselves. Cows, pigs and chickens have inherited instinctive behaviors from their wild ancestors: chickens like to build nests for their eggs, pigs love to dig into the moist earth, and cows enjoy grazing in the sunshine. The animals become stressed when they are unable to act out these behaviors.

On small, family farms, animals are usually handled in kinder, more environmentally sound ways. Adopting this approach on factory farms is costly and easy to avoid where regulation of animal welfare is poor and consumers don’t know or don’t care about the stresses animals face when penned up all day, every day, unable to move.

Cruelty to animals, deforestation, fecal pollution, the extravagant waste of water and the use of food grains to feed animals are all real problems of agriculture if the animals are just seen as cogs in the factory. But I have seen family farms in Latin America, Africa and Bangladesh where animals are treated a bit like they were in Portugal in the 1980s. The animals are kept clean without big hoses of water. The manure is used as fertilizer instead of being stored in lakes of filth. The animals eat at least some crop residues and spend at some time outdoors. The cows do still fart on family farms, but most other environmental problems are mitigated. Governments and the public should be thinking of more ways to encourage shorter food chains, decent prices for family farmers, enforcement of better standards, and research on appropriate technologies.

Enlightened Agroecology August 4th, 2019 by

Vea la versi√≥n en espa√Īol a continuaci√≥n

Francisco ‚ÄúPacho‚ÄĚ Gangotena grew up in the countryside of Ecuador and decided that the best way to help smallholder farmers was to get an education. So, he went abroad for a Ph.D. in anthropology. He came home feeling like ‚Äúthe divine papaya‚ÄĚ, he says, thinking that he could change the world with his doctorate.

After a year of teaching at the university, Pacho wanted do something more practical, so he and his wife Maritza sold the house and the car and bought four hectares of land for farming not too far from Quito. But making this work was going to be a huge challenge. The land had no trees and the soil was degraded.

From day one, the family decided that they would use no agrochemicals. They gradually improved the soil by recycling the crop residues and manure back into the soil. Pacho estimates that in this way the family has applied the equivalent of 4000 truckloads of compost since he first began farming here over 35 years ago.

I met Pacho recently on his farm in Puembo, in the Ecuadorian Andes, where he happily showed me and a few other visitors his four dairy cows. He puts sawdust in their stall to absorb their manure and urine. Each cow eats 90 kilos of feed daily and produces about 70 kilos of waste every day, equivalent to 25 tons of organic fertilizer each year for every cow. A single cow can fertilize one hectare of crops. All the manure goes onto the farm, along with all of the composted crop residues.

Pacho rotates his vegetable crops on his four-hectare farm. Potatoes are followed by broccoli, lettuce, radishes and green beans. He employs ten people and is proud that his small farm can give jobs to local families by producing healthy vegetables to sell direct to consumers in the local markets.

His grown son and daughter have also found work on the farm. Pacho jokes that he has retired and that now his daughter is his boss‚ÄĒand a pretty demanding one.

Besides recycling organic matter, Pacho also has some more unusual strategies for building up the soil. He enriches it with wood ash from pizzerias and with powdered rock from quarries. As the quarries cut stone, they leave behind a lot of powdered rock, as waste, which Pacho collects. Rocks are rich in minerals (with up to 80 elements) and are one of nature’s main components of soil.

Pacho is up front about his limitations, which adds to his credibility. A new phytoplasma disease (punta morada) is sweeping Ecuador, wiping out potato fields, including his. He also has to import vegetable seed from the USA and Europe.

But Pacho‚Äôs vegetable fields are lush, like gardens, and now surrounded by trees that the family has planted ‚Äúproviding room, board and employment for the birds and for beneficial insects,‚ÄĚ Pacho explains. An ornithologist friend counted 32 bird species on the farm, including 22 insectivores. Pacho is convinced that the birds help him to control pests without the need for insecticides. Predatory insects also provide a natural biological control of pests.

He also thinks that it is important to share what he has learned, welcoming around 32,000 smallholders to visit his farm over the years. It helps that he was the director of Swiss Aid in Ecuador for 20 years and has built a large network of collaborating farmers. Many come in groups, and some stay for several days to learn about organic farming and agroecology.

The farm’s family and staff feed us a big lunch of kale salad, potato soup and a lasagna made with green leaves instead of pasta. All vegetarian and delicious. The farm has a clear emphasis on nutritious food and produces lots of it. By intercropping and rotating crops, they get 92 tons of vegetables and other crops per hectare each year, a more than respectable yield by any standard. Since buying the farm, the organic matter, or carbon held in the soil has increased from 2% to 12% or more. In a hectare that is at least 500 tons of carbon.

Not everyone is in favor of organic, biological agriculture. For example, in an otherwise excellent book, Enlightenment Now, Steven Pinker argues that organic agriculture is not sustainable, because it supposedly uses more land that conventional agriculture.

In fact, in developing countries organic agriculture yields 80% more than conventional agriculture, but without the yield stagnation or decline that occurs with the high use of external inputs (see Uniformity in Diversity by IPES Food).

But Pinker, in his characteristic optimism, also writes that even though climate change is the world’s most serious problem, it can be solved if we really work on it.

That brings us back to the Gangotena family farm, which is providing jobs, and lots of healthy food, while removing carbon from the air where it is harmful and putting it underground where it is useful.  Organic agriculture may be one of the world‚Äôs greatest techniques for sequestering carbon from the atmosphere, storing in the soil as rich, black earth for productive farming.

LA LUZ DE LA AGROECOLOG√ćA

Por Jeff Bentley, 4 de agosto del 2019

Francisco “Pacho” Gangotena creci√≥ en el campo en Ecuador y decidi√≥ que la mejor manera de ayudar a los campesinos era obtener una educaci√≥n. As√≠ que, se fue al exterior para hacer un doctorado en antropolog√≠a. Lleg√≥ a casa sinti√©ndose como “la divina papaya “, dice, pensando que podr√≠a cambiar el mundo con su doctorado.

Despu√©s de un a√Īo de ense√Īar en la universidad, Pacho quer√≠a hacer algo m√°s pr√°ctico, as√≠ que √©l y su esposa Maritza vendieron la casa y el auto y compraron cuatro hect√°reas de tierra cerca de Quito. Pero la agricultura iba a ser un gran desaf√≠o. La tierra no ten√≠a √°rboles y el suelo estaba degradado.

Desde el primer d√≠a, la familia decidi√≥ que no usar√≠a agroqu√≠micos. Poco a poco mejoraron el suelo volviendo a incorporar los rastrojos y el esti√©rcol. Pacho estima que de esta manera la familia ha aplicado el equivalente a 4000 camiones de compost desde que empezaron a trabajar la tierra hace 35 a√Īos.

Conoc√≠ a Pacho hace poco en su finca en Puembo, en los Andes ecuatorianos, donde con toda felicidad √©l mostr√≥ a m√≠ y a algunos otros visitantes sus cuatro vacas lecheras. Pone aserr√≠n en su establo para absorber el esti√©rcol y la orina. Cada vaca come 90 kilos de alimento al d√≠a y produce unos 70 kilos de esti√©rcol al dia, unas 25 toneladas de abono org√°nico por vaca, al a√Īo. Cada vaca fertiliza una hect√°rea. Todo el esti√©rcol fertiliza el suelo junto con los rastrojos del campo convertidos en compost.

Pacho rota sus cultivos en sus cuatro hect√°reas de cultivo que constituyen su finca. Despu√©s de las papas pone br√≥coli, lechuga, r√°banos y arvejas. Emplea a diez personas y est√° orgulloso de que su peque√Īa finca d√© empleo a las familias locales, produciendo verduras sanas para venderlas directamente a los consumidores en los mercados locales.

Su hijo y su hija también traban en la finca. Pacho bromea que se ha jubilado y que ahora su hija es su jefa, y que es muy dura.

Adem√°s de reciclar la materia org√°nica, Pacho tambi√©n tiene algunas estrategias m√°s originales para crear suelo. La enriquece con ceniza de le√Īa de pizzer√≠as y con el polvo de roca de las canteras. Como las canteras cortan piedra, dejan mucha roca en polvo, como desecho, que Pacho recoge. La rocas son ricas en minerales (hasta 80 elementos) y constituyen uno de los principales componentes naturales del suelo.

Pacho admite francamente sus limitaciones, lo cual le da m√°s credibilidad. Un nuevo fitoplasma (una enfermedad‚ÄĒpunta morada) est√° arrasando con las papas del Ecuador, incluido las suyas. Tambi√©n tiene que importar varias de sus semillas de hortalizas de los Estados Unidos y Europa.

Pero las hortalizas de Pacho son exuberantes, como jardines, y ahora est√°n rodeados de √°rboles que la familia ha plantado “para dar ‚Äėroom and board‚Äô y trabajo a los p√°jaros e insectos ben√©ficos”, explica Pacho. Un amigo ornit√≥logo cont√≥ 32 especies de aves en la granja, incluyendo 22 insect√≠voros. Pacho est√° convencido de que las aves le ayudan a controlar las plagas sin necesidad de usar insecticidas. Los insectos depredadores tambi√©n hacen un control biol√≥gico natural de las plagas.

Tambi√©n cree que es importante compartir lo que ha aprendido y 32.000 campesinos han visitado su granja a lo largo de los a√Īos. Es una ventaja haber sido director de Swiss Aid en Ecuador durante 20 a√Īos y ha creado una amplia red de agricultores colaboradores. Muchos vienen en grupos, y algunos se quedan varios d√≠as para aprender sobre la agricultura org√°nica y la agroecolog√≠a.

La familia y el personal de la granja nos alimentan con un gran almuerzo de ensalada de col rizada, sopa de papas y una lasa√Īa de hojas verdes sin pasta. Todo vegetariano y delicioso. La finca tiene un claro √©nfasis en la comida nutritiva, la cual produce en abundancia. A trav√©s del policultivo y la rotaci√≥n de cultivos, obtienen 92 toneladas de hortalizas y productos agr√≠colas por a√Īo en las cuatro hect√°reas, por a√Īo, m√°s que respetables bajo cualquier sistema. Desde que compr√≥  la finca, la materia org√°nica o carbono retenido en el suelo ha subido del 2% al 12% o m√°s. En una hect√°rea de al menos 500 toneladas de carbono.

No todos están a favor de la agricultura orgánica y biológica. Por ejemplo, en un libro por lo demás excelente, Enlightenment Now, Steven Pinker argumenta que la agricultura orgánica no es sostenible, porque supuestamente usa más tierra que la agricultura convencional.

De hecho, en los países en desarrollo la agricultura orgánica rinde un 80% más que la agricultura convencional, pero sin los rendimientos estancados o en disminución que sucede con el alto uso de insumos externos (véase Uniformity in Diversity por IPES Food).

Pero Pinker, con su caracter√≠stico optimismo, a√Īade que aunque el cambio clim√°tico es el problema m√°s grave del mundo, puede resolverse si realmente trabajamos en eso.

Esto nos lleva de nuevo a la granja de la familia Gangotena, que crea puestos de trabajo y produce abundantes alimentos saludables, a la vez que extrae el carbono del aire donde hace da√Īo y lo pone bajo tierra donde hace bien.
