Wind erosion and the great quinoa disaster December 30th, 2018 by

Bolivian agronomist Genaro Aroni first told me how quinoa was destroying the southwest Bolivian landscape some 10 years ago, when he came to Cochabamba for a writing class I was teaching. Ever since then I wanted to see for myself how a healthy and fashionable Andean grain was eating up the landscape in its native country.

I recently got my chance, when Paul and Marcella and I were making videos for Agro-Insight. Together with Milton Villca, an agronomist from Proinpa, we met Genaro in Uyuni, near the famous salt flats of Bolivia. Genaro, who is about to turn 70, but looks like he is 55, told us that he had worked with quinoa for 41 years, and had witnessed the dramatic change from mundane local staple to global health food. He began explaining what had happened.

When Genaro was a kid, growing up in the 1950s, the whole area around Uyuni, in the arid southern Altiplano, was covered in natural vegetation. People grew small plots of quinoa on the low hills, among native shrubs and other plants. Quinoa was just about the only crop that would survive the dry climate at some 3,600 meters above sea level. The llamas roamed the flat lands, growing fat on the native brush. In April the owners would pack the llamas with salt blocks cut from the Uyuni Salt Flats (the largest dry salt bed in the world) and take the herds to Cochabamba and other lower valleys, to barter salt for maize and other foods that can‚Äôt be grown on the high plains. The llama herders would trade for potatoes and chu√Īo from other farmers, supplementing their diet of dried llama meat and quinoa grain.

Then in the early 1970s a Belgian project near Uyuni introduced tractors to farmers and began experimenting with quinoa planted in the sandy plains. About this same time, a large-scale farmer further north in Salinas also bought a tractor and began clearing scrub lands to plant quinoa.

More and more people started to grow quinoa. The crop thrived on the sandy plains, but as the native brushy vegetation grew scarce so the numbers of llamas began to decline.

Throughout the early 2000s the price of quinoa increased steadily. When it reached 2500 Bolivianos for 100 pounds ($8 per kilo) in 2013, many people who had land rights in this high rangeland (the children and grandchildren of elderly farmers) migrated back‚ÄĒor commuted‚ÄĒto the Uyuni area to grow quinoa. Genaro told us that each person would plow up to 10 hectares or so of the scrub land to plant the now valuable crop.

But by 2014 the quinoa price slipped and by 2015 it crashed to about 350 Bolivianos per hundredweight ($1 per kilo), as farmers in the USA and elsewhere began to grow quinoa themselves.

Many Bolivians gave up quinoa farming and went back to the cities. By then the land was so degraded it was difficult to see how it could recover. Still, Genaro is optimistic. He believes that quinoa can be grown sustainably if people grow less of it and use cover crops and crop rotation. That will take some research. Not much else besides quinoa can be farmed at this altitude, with only 150 mm (6 inches) of rain per year.

Milton Villca took us out to see some of the devastated farmland around Uyuni. It was worse than I ever imagined. On some abandoned fields, native vegetation was slowly coming back, but many of the plots that had been planted in quinoa looked like a moonscape, or like a white sand beach, minus the ocean.

Farmers would plow and furrow the land with tractors, only to have the fierce winds blow sand over the emerging quinoa plants, smothering them to death.

Milton took us to see one of the few remaining stands of native vegetation. Not coincidentally, this was near the hamlet of Lequepata where some people still herd llamas. Llama herding is still the best way of using this land without destroying it.

Milton showed us how to gather wild seed of the khiruta plant; each bush releases clouds of dust-like seeds, scattered and planted by the wind. Milton and Genaro are teaching villagers to collect these seeds and replant, and to establish windbreaks around their fields, in an effort to stem soil erosion. I’ve met many agronomists in my days, but few who I thought were doing such important work, struggling to save an entire landscape from destruction.

DESTRUYENDO EL ALTIPLANO SUR CON QUINUA

Jeff Bentley, 30 de diciembre del 2018

El ingeniero agr√≥nomo boliviano Genaro Aroni me cont√≥ por primera vez c√≥mo la quinua estaba destruyendo los suelos del suroeste boliviano hace unos 10 a√Īos, cuando vino a Cochabamba para una clase de redacci√≥n que yo ense√Īaba. Desde aquel entonces quise ver por m√≠ mismo c√≥mo el af√°n por un sano grano andino podr√≠a comer el paisaje de su pa√≠s natal.

Recientemente tuve mi oportunidad, cuando Paul, Marcella y yo hac√≠amos videos para Agro-Insight. Junto con Milton Villca, un agr√≥nomo de Proinpa, conocimos a Genaro en Uyuni, cerca de las famosas salinas de Bolivia. Genaro, que est√° a punto de cumplir 70 a√Īos, pero parece que tiene 55, nos dijo que hab√≠a trabajado con la quinua durante 41 a√Īos, y que hab√≠a sido testigo del cambio dram√°tico de un alimento b√°sico local y menospreciado a un renombrado alimento mundial. Empez√≥ a explicar lo que hab√≠a pasado.

Cuando Genaro era un ni√Īo en la d√©cada de 1950, toda el √°rea alrededor de Uyuni, en el √°rido sur del Altiplano, estaba cubierta de vegetaci√≥n natural. La gente cultivaba peque√Īas parcelas de quinua en los cerros bajos, entre arbustos nativos (t‚Äôolas) y la paja brava. La quinua era casi el √ļnico cultivo que sobrevivir√≠a al clima seco a unos 3.600 metros sobre el nivel del mar. Las llamas deambulaban por las llanuras, engord√°ndose en el matorral nativo. En abril los llameros empacaban los animales con bloques de sal cortados del Salar de Uyuni (el m√°s grande del mundo) y los llevaban en tropas a Cochabamba y otros valles m√°s bajos, para trocar sal por ma√≠z y otros alimentos que no se pueden cultivar en las altas llanuras. Los llameros intercambiaban papas y chu√Īo de otros agricultores, complementando su dieta con carne de llama seca y granos de quinua.

Luego, a principios de la década de 1970, un proyecto belga cerca de Uyuni introdujo tractores a los agricultores y comenzó a experimentar con quinua sembrada en las pampas arenosas. Por esa misma época, un agricultor a gran escala más al norte, en Salinas, también compró un tractor y comenzó a talar los matorrales para sembrar quinua.

Cada vez más gente empezó a cultivar quinua. El cultivo prosperó en las llanuras arenosas, pero a medida que la vegetación nativa de arbustos se hizo escasa, había cada vez menos llamas.

A lo largo de los primeros a√Īos de la d√©cada de 2000, el precio de la quinua aument√≥ constantemente. Cuando lleg√≥ a 2500 bolivianos por 100 libras ($8 por kilo) en 2013, muchas personas que ten√≠an derechos sobre la tierra en esta pampa alta (los hijos y nietos de los agricultores viejos) retornaron a la zona de Uyuni para cultivar quinua. Genaro nos dijo que cada persona araba hasta 10 hect√°reas de t‚Äôola para plantar el ahora valioso cultivo.

Pero para el 2014 el precio de la quinua comenzó a bajar y para el 2015 se colapsó a cerca de 350 bolivianos por quintal ($1 por kilo), a medida que los agricultores en los Estados Unidos y en otros lugares comenzaron a cultivar quinua ellos mismos.

Muchos bolivianos dejaron de cultivar quinua y regresaron a las ciudades. Para entonces la tierra estaba tan degradada que era dif√≠cil ver c√≥mo podr√≠a recuperarse. Sin embargo, Genaro es optimista. √Čl cree que la quinua puede ser cultivada de manera sostenible si la gente la cultiva menos y usa cultivos de cobertura y rotaci√≥n de cultivos. Eso requerir√° investigaci√≥n. No se puede cultivar mucho m√°s que adem√°s de la quinua a esta altitud, con s√≥lo 150 mm de lluvia al a√Īo.

Milton Villca nos llevó a ver algunas de las parcelas devastadas alrededor de Uyuni. Fue peor de lo que jamás imaginé. En algunas parcelas abandonados, la vegetación nativa regresaba lentamente, pero muchas de las chacras que habían sido sembradas en quinua parecían la luna, o una playa de arena blanca, menos el mar.

Los agricultores araban y surcaban la tierra con tractores, sólo para que los fuertes vientos soplaran arena sobre las plantas emergentes de quinua, ahogándolas y matándolas.

Milton nos llev√≥ a ver uno de los pocos manchones de vegetaci√≥n nativa que queda. No por casualidad, esto estaba cerca de una peque√Īa comunidad de llameros, que queda en Lequepata. El pastoreo de llamas sigue siendo la mejor manera de usar esta tierra sin destruirla.

Milton nos mostr√≥ c√≥mo recolectar semillas silvestres de la planta khiruta; cada arbusto libera nubes de semillas parecidas al polvo, dispersas y sembradas por el viento. Los Ings. Milton y Genaro est√°n ense√Īando a los comuneros a recolectar estas semillas y replantar, y a establecer barreras contra el viento alrededor de sus campos, en un esfuerzo por detener la erosi√≥n del suelo. He conocido a muchos agr√≥nomos a trav√©s de los a√Īos, pero pocos que en mi opini√≥n hac√≠an un trabajo tan importante en comunidades remotas, luchando para salvar un paisaje entero de la destrucci√≥n.

Organic agriculture and mice December 9th, 2018 by

Some practices are harder to introduce to farmers than others. In Europe, environmental degradation caused by industrial agriculture has given rise to new forms of subsidies for farmers to provide specific environmental services, such as planting hedgerows or keeping wild flower strips around their fields. In developing countries, however, environmental subsidies are non-existent and hence curbing environmental degradation can be extra challenging.

Recent developments in the global quinoa trade have devastated the fragile ecosystem of the Bolivian Altiplano. As quinoa production intensified, farmers ploughed up large sections of native vegetation, which left the soil prone to wind erosion. With the thin fertile top soil being blown away and young quinoa plants being covered with sand, many farmers abandonned their land and moved to the cities. The loss of native vegetation also limited the forage available for the llamas and vicu√Īas.

To address this problem, the research organisation Proinpa is trying hard to re-introduce native plants. If native plants could be grown as live barriers around quinoa fields, they would provide fodder and at the same time reduce wind erosion. But some farmers are reluctant to adopt this technology. Planting live barriers costs money, labour and takes up part of their land.

Many of the farmers who plant barriers belong to associations that market organic quinoa. Organic certification ensures that farmers get higher prices, as long as they follow certain practices (such as planting hedges) that contribute to a better social and natural environment. Subsidies for organic farming are rare in developing countries, premiums from certification schemes can partly make up for missing government subsidies, unless pests also like organic crops.

Farmers who grow live barriers told Proinpa that the hedges attract mice who can destroy young quinoa seedlings. Mice are also attracted to the harvested grain as it dries in the field, before threshing. If the quinoa is not stored properly, mice often get into the warehouses. When droppings foul the grain, the crop is rejected for organic trade.

Organic agriculture can be a blessing to boost the income of smallholder farmers and to protect the environment. But as this example shows, organic farmers are prone to additional challenges. Farmers on the Bolivian Altiplano set traps by burying cans partly filled with water to drown the mice. Frustrated quinoa growers also stomp on mice burrows in thie fields or leave quinoa chaffe at the entrance of mice holes, so they eat this and leave the young quinoa untouched.

Every new technology has unintended consequences. Perhaps no one anticipated that live barriers would protect mice, and the soil. Yet farmers who have planted the barriers see their benefit and are willing to find new ways to take on the mice.

Golden urine September 16th, 2018 by

Cities are throwing away a fortune in urine, I learned the other day while visiting Dr. Noemi Stadler-Kaulich, a German agro-forester and long-time resident of Bolivia. The urine from an average person contains $85 dollars¬ī worth of phosphorous in one year, Noemi explained. Urine is rich in phosphorous, nitrogen and potassium, the main elements of fertilizer (chemical or organic). A metropolitan area like Cochabamba, with 1,200,000 people, flushes away over $100 million worth every year, Naomi explained, just in the phosphorous from urine, turning the valley‚Äôs main river, the R√≠o Rocha, into an open sewer.

Noemi has dry latrines on her farm near the town of Vinto, on the edge of the Cochabamba metropolitan area. If you have never sat a dry latrine it can take some getting used to. There is a large hole for feces and a smaller one, up front, to collect the urine, which can be used right away as fertilizer. After defecating, one walks around to the back of the latrine and adds a handful of wood ash to the deposit, which is composted once the container is full. Dried, composted human feces are an excellent, dry fertilizer with little or no smell.

I used to have a nice dry latrine in Honduras. It used no water and made little odor. But dry latrines do take a little management. At the time I was worried about pathogens and had samples from dry latrines analyzed at a laboratory in Tegucigalpa. The samples were free of the most common parasites and pathogens. Dry latrines compost the night soil for at least six months, which helps to kill pathogens. Still, this demands some competent management.

At our home in Cochabamba, we began recycling urine about a year ago. Urine is easy to collect in a jar or bottle or while sitting on a chamber pot. You can mix urine with water or apply it straight to the soil, near plants. We put most of our urine on the compost pile, where the pee helps to speed up the decomposition of paper and dry plants. Urine in a compost heap has no smell at all; perhaps in part because the nitrogen in urine quickly breaks down into ammonia.

I have not yet been able to confirm Noemi’s estimate of the value of phosphorous in urine, not to mention the potassium and nitrogen, but urine is certainly worth something as fertilizer. Recycling urine also helps to save water. Conventional toilets waste up to six liters of precious water to flush 300 ml of urine.

As it is now, modern conventional agriculture applies nitrogen, phosphorous and potassium (NPK) to crops, and (at least some of) the nutrients become part of the living plants, which are eaten by people and later discarded as human waste. No doubt in the future clever people will find other clean, convenient ways to recycle this NPK, without wasting water. In the meantime, saving urine as fertilizer is a golden opportunity.

As the waters recede July 1st, 2018 by

Peasant farmers can be quick to seize an opportunity, and when the benefit is clearly high, farmers may skip the experimental stage and go straight to a new practice on a massive scale.

In the lower Gangetic Delta in southwest Bangladesh, people live just centimeters above sea level. Getting rid of excess water can make all the different between harvest and hunger.

In the 1960s, earthen embankments were built around certain large areas of land.

The newly dry land inside these dykes is called a polder. Successful farming in the polder depends on having large draining canals, snaking through the muddy land, to carry water to the river.

In 2000, the 10 km-long Amodkhali Canal silted up. So during the winter rainy season the water had nowhere to go. A vast area in the middle of Polder 2 became a seasonal lake. Villagers hung on, growing rice in the dry season. Many migrated for wage labour in the winter.

Then in May 2017, Blue Gold (a program implemented by the government of Bangladesh) began to re-excavate the Amodkhali Canal.  By July they had dug out 8.4 km. It was a big job. At 2.5 meters deep and 6 meters wide, thousands of cubic meters of mud had to be moved. Some was done by machinery and some by hand. Groups of women were organised into Labour Contracting Societies (LCS) to earn money doing the work.

Local people near the canal saw the work. Even those living far away heard about it, and when the rains came in July 2017, farmers could see with their own eyes that the rainwater was draining away.

Like a river, a drainage canal has a sort of watershed, called a catchment area. This canal drains a roughly tear-drop shaped area some four by six kilometres: a big place. The thousands of farmers in the area didn’t have to be begged or cajoled into planting rice: they just did it.

My colleagues and I met local farmer Nozrul Islam near the banks of the canal. He said that he was so happy with the canal. He has two hectares of land and when the water drained off, nobody told him to plant rice. He simply went to Khulna, a neighbouring district, and bought rice seed for all of his land. He hadn’t planted winter rice for over 16 years.

Nozrul’s experience was replicated all over the area. In the village of Koikhali, a group of women told us that they also planted winter (amon) rice last year.

There was no experimentation, no hesitation. People simply re-introduced a winter rice crop into their cropping system, which they had not grown for almost a generation. The total catchment area is 4326 ha. That first year they planted 2106 hectares of winter rice, and harvested 12,000 tons or rice. Much of this rice was sold on the national market.

Innovating in the homeland of lupins May 20th, 2018 by

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

Rhimer Gonzales is an agronomist who has worked in Morochata, in the Bolivian Andes, for three years, introducing new, sweet varieties of lupin: the beans can be eaten directly without soaking them to remove the natural toxins. Rhimer has also been trying, without success, to encourage folks to grow lupins in rows, just like other crops.

Farmers have been growing lupins here for a long time. Wild lupins are common in the canyons of Morochata, an area close to the center of origin for this crop with the gorgeous flowers and edible beans. It seems unlikely that local farmers could learn new ways to grow lupins, yet the use of a farmer learning video has triggered innovations.

I accompanied Rhimer during a recent visit, when we met Serafina Córdoba. She was busy washing dishes under a tree in front of her house, hurrying to finish so she get her kids started on their homework. She explained that the family got a DVD on soil conservation at a meeting of the sindicato (local village organization). Afterwards she watched the videos again with her husband and children. She remembered several of the videos, especially one on lupins and another on earthworms.

When we asked if the family had done anything new after watching the videos, at first she demurred. She wasn‚Äôt sure if the changes they had made in selecting lupin seed were important enough. Before, they would just take a handful of seeds and plant them. After seeing the video she picked out the big, healthy seeds, and the family planted those. The crop is flowering in the field now and do√Īa Sefarina said it looks better than in previous years.

The family also noticed in the video that people planted in rows, in furrows made with oxen. So do√Īa Serafina and her husband Jorge planted a whole field with oxen. She was pleased that this was a fast way to plant‚ÄĒclearly saving time is important for busy families. Rhimer confirmed that planting with oxen was a major innovation. Before, people planted just one row of lupins around the field.

The video emphasized seed selection. But it also showed row planting with oxen, because that is a routine practice in Anzaldo, where most of the video was filmed. Lupins are a more important crop in Anzaldo than in Morochata, even though both municipalities are in Cochabamba.

The value of filming farmers at work is that other farmers watching the video can learn all sorts of unexpected things. Conventional practice in one area can be an interesting innovation for another.

Rhimer explained that he selected the lupin video to show in Morochata because he thought it would be convincing. He was pleased to learn about do√Īa Serafina‚Äôs experience, because the video succeeded in convincing her family to not only select seed, but also to plant in rows.

Each farmer responds to a video in his or her own way. Later we met don Dar√≠o, who had also seen the videos at the meeting at the sindicato, and had later watched the DVD again with his family. Then he planted a whole field of lupins in rows. Unlike do√Īa Serafina, who said that planting in rows was easier, don Dar√≠o said it was more work. But that‚Äôs because he planted a whole field by hand with a pick, on a canyon side. Don Dar√≠o planted his lupins in straight lines up the hillside, and parallel to the slope as well, forming a grid pattern.

Rhimer explained that this lupin was a new, sweet variety and the plants were smaller than those of the bitter lupin that was previously planted in Morochata, so farmer had planted the new, shorter variety too far apart. Rhimer was also frustrated that the farmers were not watering the lupin enough. ‚ÄúIrrigating it one more time would have done it good.‚ÄĚ There is plenty of water here. But folks are still not treating lupins like a major crop, worth irrigating.

Change takes time, even when a community has a good extensionist like Rhimer. I thought he was doing well, successfully encouraging people to plant a new variety, and with a little help from the lupin video, inducing people to select healthy seed and plant in lines. As farmers grow familiar with the new variety they might learn to plant it closer together and water it a bit more, especially if a market develops for it.

Rhimer was modest about his own contribution to changing farmer practices. I suggested that the farmers’ responses to the videos were closely related to his work in the community. But Rhimer said that even though he had shared ideas with people of Morochata for a long time, it was the video that finally convinced the farmers to try row planting and seed selection.

Rhimer’s hard earned standing with farmers meant they were receptive to new ideas. But the videos provided additional, concrete evidence that that the new practices actually worked.

INNOVANDO EN LA CUNA DEL TARWI

Por Jeff Bentley, 20 de mayo del 2018

Rhimer Gonzales es un agr√≥nomo que ha trabajado en Morochata, en los Andes bolivianos, durante tres a√Īos, introduciendo nuevas variedades dulces de tarwi (tambi√©n conocido como lupino, chocho, y altramuz). Sus granos se pueden comer directamente sin remojarlos para eliminar las toxinas naturales. Rhimer tambi√©n ha intentado, sin √©xito, alentar a las personas a cultivar tarwi en hileras, al igual que otros cultivos.

Los agricultores han estado cultivando tarwi aqu√≠ durante mucho tiempo. Los tarwis silvestres son comunes en los ca√Īones de Morochata, un √°rea cercana al centro de origen de este cultivo, con hermosas flores y frijoles comestibles. Parece poco probable que se podr√≠a ense√Īar algo nuevo a agricultores con tanta experiencia con el tarwi, sin embargo, el uso de un video de aprendizaje ha desencadenado algunas innovaciones.

Acompa√Ī√© a Rhimer durante una visita reciente, cuando conocimos a Serafina C√≥rdoba. Estaba ocupada lavando los platos debajo de un √°rbol en frente de su casa, apurada a terminar para poder ayudar a sus hijos con sus tareas. Ella explic√≥ que la familia recibi√≥ un DVD sobre la conservaci√≥n del suelo en una reuni√≥n del sindicato (organizaci√≥n local del pueblo). Luego ella mir√≥ los videos nuevamente con su esposo e hijos. Ella record√≥ los videos, especialmente uno sobre tarwi y otro sobre lombrices.

Cuando le preguntamos si la familia hab√≠a hecho algo nuevo despu√©s de ver los videos, al principio ella se neg√≥. No estaba segura que los cambios que hab√≠an hecho en la selecci√≥n de semillas de lupino eran lo suficientemente importantes. Antes, simplemente tomaban un pu√Īado de semillas y las sembraban. Despu√©s de ver el video, ella seleccion√≥ las semillas grandes y saludables, y la familia las sembr√≥. Ahora el cultivo est√° en flor y do√Īa Sefarina dice que se ve mejor que en a√Īos anteriores.

La familia tambi√©n not√≥ en el video que la gente sembraba en hileras, en surcos hechos con bueyes. Entonces do√Īa Serafina y su esposo Jorge plantaron una parcela entera con bueyes. Estaba contenta de que era r√°pido sembrar as√≠; para una familia ocupada es imprescindible ahorrar tiempo. Rhimer confirm√≥ que sembrar con bueyes fue una gran innovaci√≥n. Antes, la gente sembraba solo una fila de tarwis alrededor de la parcela.

El video enfatizó la selección de semilla. Pero también mostró la siembra en surcos con bueyes, porque esa es una práctica convencional en Anzaldo, donde se filmó la mayor parte del video. El tarwi es más importante en Anzaldo que en Morochata, aunque ambos municipios están en Cochabamba.

El valor de filmar a los agricultores mientras trabajan es que otros agricultores que miran el video pueden aprender todo tipo de cosas inesperadas. La práctica convencional en una zona puede ser una innovación interesante para otra.

Rhimer explic√≥ que seleccion√≥ el video de tarwi para mostrar en Morochata porque pens√≥ que ser√≠a convincente. Le agrad√≥ conocer la experiencia de do√Īa Serafina, porque el video logr√≥ convencer a su familia no solo de seleccionar semillas, sino tambi√©n de plantar en filas.

Cada agricultor responde a un video a su manera. M√°s tarde nos encontramos con don Dar√≠o, quien tambi√©n hab√≠a visto los videos en la reuni√≥n en el sindicato, y luego hab√≠a visto el DVD otra vez con su familia. Luego plant√≥ una parcela entera de tarwi en fila. A diferencia de Do√Īa Serafina, quien dijo que plantar en hileras era m√°s f√°cil, don Dar√≠o dijo que era m√°s trabajo. Pero eso es porque sembr√≥ un campo entero a mano con una picota, en ladera del ca√Ī√≥n. Don Dar√≠o sembr√≥ su tarwi en l√≠nea recta hacia arriba, y de lado a lado, como cuadr√≠cula.

Rhimer explic√≥ que este tarwi era una variedad nueva y dulce y que las plantas eran m√°s peque√Īas que las del tarwi amargo que ya se conoc√≠a en Morochata, por lo que los agricultores hab√≠an sembrado la variedad nueva muy distanciada. Rhimer tambi√©n estaba frustrado porque los campesinos no estaban regando lo suficiente al lupino. “Regarlo una vez m√°s lo hubiera hecho bien”. Aqu√≠ hay mucha agua. Pero la gente todav√≠a no est√° tratando al tarwi como un cultivo importante, que vale la pena regar.

El cambio lleva tiempo, incluso cuando una comunidad tiene un buen extensionista como Rhimer. Yo admiraba su trabajo, animando la gente a sembrar una nueva variedad y con un poco de ayuda del video de tarwi, induciendo a los agricultores a seleccionar semilla y sembrar en línea. A medida que los agricultores se familiarizan con la nueva variedad, podrían aprender a sembrarla más cerca y regarla un poco más, especialmente si se desarrolla un mercado para el tarwi.

Rhimer modestamente atribuía mucho del cambio en prácticas a los videos. Sugerí que el cambio estaba estrechamente relacionado con su trabajo en la comunidad. Pero Rhimer dijo que aunque había compartido ideas con la gente de Morochata durante mucho tiempo, fue el video que finalmente convenció a los agricultores a probar la siembra en líneas y la selección de semilla.

Por su trabajo constante, Rhimer ha ganado la confianza de los agricultores para que reciban a las nuevas ideas. Pero los videos dieron evidencia adicional y concreta de que las nuevas pr√°cticas realmente funcionaran.
