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

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

Bolivian agronomist Gernaro 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 Gernaro 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.

Awakening the seeds December 16th, 2018 by

In much of the Bolivian Altiplano, the native vegetation has been largely stripped away. A few people are doing something to replant the vegetation, but it is surprisingly difficult to germinate the seeds of native plants.

These Andean high plains were once covered by scrub land, comprising low-lying bushes, needle grasses and other hardy plants well adapted to the harsh conditions. Llamas foraged on this waist-high forest without damaging it. But as more land was plowed up for quinoa, and more of the bushes were cut for firewood, the native vegetation started to vanish.

Rural families in this part of Bolivia used to make long, narrow stacks of dried brush. But the bushes are now mostly gone, and so are the stacks of firewood.

Fortunately, explains plant researcher, Dr. Alejandro Bonifacio, people are now cooking with bottled natural gas, so they don’t need to uproot brush for firewood, but this respite has come too late. In many places, the deforestation has been so complete that there are no seed-bearing plants left to provide for natural regeneration. So, Dr. Bonifacio and his team travel around the Altiplano, collecting seed of different shrubs, planting the seed in nurseries and then taking the seedlings to sympathetic farmers who are interested in restoring the dry plains.

Seeds of wild plants will seldom germinate if simply scattered on the ground. The plants are adapted to harsh environments, and the seed enters dormancy, only to be awakened by the kiss of some specific environmental signal.

Bonifacio and his students study each plant to determine what will break its dormancy.¬† For example, the k‚Äôawchi, a small woody plant, is so adapted to this land of high winds and rocky soil that its tiny seed must be tumbled over the rough ground and ‚Äúscarified‚ÄĚ before it will germinate. Bonifacio and his team have also learned that it can be scarified by rubbing it in sand or by putting it in a weak solution of sodium hypoclorite for 20 minutes.

On the arid Altiplano, much of the native vegetation is cactus, some of it bearing delicious fruit. In a boutique restaurant in the big city of La Paz, Bonifacio was shocked to that the chef was asking for a supply of one native cactus, called achakana. Yes, achakana is edible, but it takes many years to grow to the size of a tennis ball. The Aymara people used to eat the cactus as famine food when the crops failed, but achakana could be driven to extinction if it starts to be served up in the fashionable eateries of La Paz. So, Bonifacio taught himself how to propagate it.

It was tricky. At first, the seed failed to germinate. Bonifacio learnt that as the fruit matures the seed goes into a deep dormancy. Then one day by serendipity Bonifacio discovered a little bag of fruit had had been harvested green and then forgotten. When he opened the rotting fruit, he found that all of the seeds were germinating. He proudly showed me a small, three-year old plant that he had grown from seed.

The pasak’ana is another endangered cactus that grows so tall that the Andean people once used its ribs to roof their houses. The fruit is also delicious, yet getting the seed to germinate was impossible. Then Bonifacio found that the pasak’ana seed would germinate if it was taken from immature fruit. With the help of a student he now has 1200 little pasak’ana plants, all in demand from a municipal government in Oruro which wants to plant them out.

More people than ever want to grow native plants for fruit, fodder and soil conservation, but each species has its own unique requirements for coming to life. Fortunately, there are patient researchers working to unlock these mysteries and come up with practical recommendations that can help restore degraded lands.

Scientific names

The k‚Äôawchi is Suaeda foliosa, belonging to the unfortunately named ‚Äúseepweed‚ÄĚ genus.

The achakana is Neowerdemannia vorwerckii.

The pasak’ana is Trichocereus pasacana (Echinopsis atacamensis subs. pasacana)

DESPERTANDO LAS SEMILLAS

Por Jeff Bentley, 16 de diciembre del 2018

En gran parte del Altiplano Boliviano, la vegetación nativa ha sido arrancada. Hay personas que se dedican a replantar la vegetación, pero es sorprendentemente difícil germinar las semillas de plantas nativas.

Estos altiplanos andinos estaban cubiertos de t‚Äôolares (matorrales), que inclu√≠an arbustos bajos, paja brava y otras plantas fuertes y bien adaptadas a las duras condiciones. Las llamas se forrajeaban en este bosque enano sin da√Īarlo. Pero a medida que m√°s tierra fue arada para la quinua, y m√°s arbustos fueron cortados para le√Īa, la vegetaci√≥n nativa comenz√≥ a desaparecer.

Las familias rurales de esta parte de Bolivia sol√≠an amontonar las t‚Äôolas, o arbustos, en forma de cercos largos y delgados, para le√Īa.¬† Pero la mayor√≠a de los arbustos han desaparecido, as√≠ como los montones de le√Īa.

Afortunadamente, explica el investigador de plantas, el Dr. Alejandro Bonifacio, la gente ahora cocina con gas natural en garrafa, as√≠ que no necesitan arrancar las t‚Äôolas para le√Īa, pero este respiro ha llegado muy tarde. En muchos lugares, la deforestaci√≥n ha sido tan completa que ya no quedan plantas madres para la regeneraci√≥n natural. As√≠, el Dr. Bonifacio y su equipo viajan por el Altiplano, recolectando semillas de diferentes arbustos, sembrando las semillas en viveros y luego llevando los plantines a agricultores que simpatizan con la revegetaci√≥n de las pampas secas.

Las semillas de las plantas silvestres rara vez germinan si simplemente se echan al suelo. Las plantas se adaptan a ambientes hostiles, y la semilla entra en dormancia, s√≥lo para ser despertada por el beso de alguna se√Īal ambiental espec√≠fica.

Bonifacio y sus alumnos estudian cada planta para determinar qu√© romper√° su dormancia.¬† Por ejemplo, el k’awchi, una peque√Īa planta le√Īosa, est√° tan adaptado a esta tierra de vientos fuertes y suelo pedregosa que su peque√Īa semilla tiene que caer sobre el suelo √°spero y “escarificarse” para poder germinar. Bonifacio y su equipo tambi√©n han aprendido que una alternativa frotarlo en arena o dejar la semilla por 20 minutos en una soluci√≥n d√©bil de hipoclorito de sodio.

En el √°rido Altiplano, gran parte de la vegetaci√≥n nativa es de cactus, algunos de los cuales producen ricos frutos. En un restaurante boutique en la gran ciudad de La Paz, Bonifacio se sorprendi√≥ al ver un cactus nativo, llamado achakana, solicitado para el men√ļ. La achakana s√≠ es comestible, pero tarda muchos a√Īos para alcanzar el tama√Īo de una pelota de tenis. Los aymaras sol√≠an comer el cactus como alimento en tiempos de hambre cuando las cosechas fallaban, pero la achakana podr√≠a llegar a la extinci√≥n si empiezan a ser servirla en los restaurantes de moda de La Paz. As√≠ que Bonifacio se ense√Ī√≥ a s√≠ mismo a propagarlo.

Fue dif√≠cil. Al principio, la semilla no pudo germinar. Bonifacio aprendi√≥ que a medida que el fruto madura, la semilla entra en una profunda dormancia. Un d√≠a, por casualidad, Bonifacio descubri√≥ que una bolsita de fruta hab√≠a sido cosechada verde y luego olvidada. Cuando abri√≥ el fruto podrido, descubri√≥ que todas las semillas estaban germin√°ndose. Con orgullo me mostr√≥ una peque√Īa planta de tres a√Īos que √©l hab√≠a cultivado a partir de una semilla.

El pasak’ana es otro cactus en peligro de extinci√≥n que crece tan alto que los andinos usaban sus palos para techar sus casas. La fruta tambi√©n es deliciosa, sin embargo, hacer que la semilla germine era imposible. Entonces Bonifacio descubri√≥ que la semilla de pasak’ana germinar√≠a si se tomaba de un fruto inmaduro. Con la ayuda de un estudiante, ahora tiene 1200 peque√Īas plantas de pasak’ana, todas solicitadas por un gobierno municipal de Oruro que quiere plantarlas.

Hoy en d√≠a mucha gente quiere cultivar plantas nativas para la conservaci√≥n de la fruta, el forraje y el suelo, pero cada especie tiene sus propias necesidades √ļnicas para volver a la vida. Afortunadamente, hay pacientes investigadores que trabajan para desvelar estos misterios y presentar recomendaciones pr√°cticas que pueden ayudar a restaurar las tierras degradadas.

Carrasco National Park is the largest national park in Cochabamba, Bolivia. At over 6,000 square kilometers it is the size of Delaware, or twice the size of Luxembourg. It spans an impressive range of topographies, from the high Andes down to the rain forest. I was in the park recently with my family to see some of the sandstone caves. Our guide was a 15-year-old schoolboy named Samuel. We met him in the office of the accredited guides, next to the park rangers’ station.

Soon after we arrived, the ranger had sent Samuel a WhatsApp message, and he came quickly to lead the tour. Fortunately he was available, since school was on a two-week break. However, we got off to an inauspicious start. Samuel started his introduction talk in a soft, rapid mumble, like a bored student chanting a dull lesson. He seemed not to know or care what he was talking about. But first impressions were misleading, as we soon found out.

Some of my more patient family members were able to draw Samuel out. By the time he had taken us across a mountain stream in a hand-powered cable car, Samuel was explaining that the balsa tree, which gives the light wood for airplanes, is actually quite heavy when it is standing timber. He then told us about palo santo, a tree guarded by ants which clear plants from around the base of the tree and keep the branches free of epiphytes. In an earlier, crueler age, people guilty of theft and even minor crimes could be tied to the tree to be tortured by the ants which inject a white poison from the needles on their abdomen.

Samuel showed a tiny species of native, stingless bee that makes its nest inside a termite nest. The bees make a honey-colored tunnel which serves as a doorway and landing pad. The tunnel is barely visible, peeking out of the large termite nest. You have to be a patient observer, like Samuel, to notice this. I was delighted to learn about the bees that move in with the termites. I have loved these little golden bees for years, but never seen them living in termite nests.

Samuel also took us to the entrance of the cave of the oil birds. Much like bats, the birds live in caverns, fly out at night and eat the fruit of palms and trees. Later, the birds regurgitate the seeds onto the cave floor. Samuel picked up six seeds from the stream flowing from the cave. He recognized all six species by their seed, which he picked out of the muck puked out by the birds.

Samuel may not have been much of a showman, but he knew his stuff. He had grown up in the area, the son of settlers from the Andes, so he had learned much about the forest by his own observations. Samuel wants to study tourism, and keep working in the park. He taught me once again the importance of being patient and willing to learn from others. Appearances can be deceiving and one wouldn’t normally expect a shy 15 year-old to be an expert naturalist. But you can always learn something if you’re willing to listen.

The palm and tree species identified by Samuel are:

Laurel (Spanish elm) Cordia aliodora. Palta laurel (unidentified). Pachubilla or caminante (walking palm) Socratea exorrhiza. Majo (açaí) Euterpe oleracea. Tembe (peach palm) Bactris gasipaes. Ramoncilla (a palm) Trichilia pallida

Other species mentioned

The oil bird is Steatornis caripensis. The stingless bee is Melipona sp.

El Parque Nacional Carrasco es el parque nacional m√°s grande de Cochabamba, Bolivia. Con m√°s de 6.000 kil√≥metros cuadrados, tiene dos terceras el √°rea de Puerto Rico. Abarca una impresionante gama de topograf√≠as, desde los altos Andes hasta el bosque lluvioso. Estuve en el parque recientemente con mi familia para ver algunas de las cuevas de piedra arenisca. Nuestro gu√≠a era un estudiante de 15 a√Īos llamado Samuel. Lo encontramos en la oficina de los gu√≠as acreditados, al lado de la estaci√≥n de los guardaparques.

Poco despu√©s de llegar, el guardabosques le envi√≥ a Samuel un mensaje por WhatsApp, y √©l vino r√°pidamente para dirigir la gira. Afortunadamente estaba disponible, ya que el colegio estaba en un receso de dos semanas. Sin embargo, tuvimos un comienzo desfavorable. Samuel comenz√≥ su charla de introducci√≥n en un murmullo suave y r√°pido, como un estudiante aburrido cantando una lecci√≥n aburrida. Parec√≠a no saber o interesarse de lo que estaba hablando. Pero las primeras impresiones fueron enga√Īosas, como pronto descubrimos.

Algunos de mis familiares más pacientes pudieron ganar la confianza de Samuel. En el tiempo que tardó en llevarnos a través de un riachuelo en un teleférico manual, Samuel explicaba que el árbol de balsa, que da la madera liviana para aviones, en realidad es bastante pesada cuando está en pie. Luego nos contó sobre el palo santo, un árbol protegido por hormigas que limpian las plantas de alrededor de la base del árbol y mantienen las ramas libres de epífitas. En una edad anterior y más cruel, las personas culpables de robo e incluso delitos menores podían ser atadas al árbol para ser torturadas por las hormigas que inyectan un veneno blanco de las agujas en su abdomen.

Samuel mostr√≥ una peque√Īa especie de abeja nativa sin aguij√≥n que hace su nido dentro de un nido de termitas. Las abejas forman un t√ļnel de color miel que sirve como entrada y plataforma de aterrizaje. El t√ļnel es apenas visible, asom√°ndose desde el gran nido de termitas. Tienes que ser un observador paciente, como Samuel, para fijarte en esto. Yo estaba encantado de aprender sobre las abejas que viven con las termitas. Hace muchos a√Īos que amo a estas peque√Īas abejas de oro, pero nunca las he visto viviendo en nidos de termitas.

Samuel también nos llevó a la entrada de la cueva de los guácharos. Son pájaros que, igual que los murciélagos, viven en cavernas, vuelan de noche y comen fruta de palmeras y árboles. Más tarde, las aves regurgitan las semillas en el suelo de la cueva. Samuel recogió seis semillas de la quebrada que fluía de la cueva. Reconoció las seis especies por sus semillas, vomitadas por los pájaros, que recogió del lodo.

Samuel no era muy teatrero, pero sab√≠a lo que hac√≠a. √Čl hab√≠a crecido en la zona, hijo de colonos de los Andes, por lo que hab√≠a aprendido mucho sobre el bosque por sus propias observaciones. Samuel quiere estudiar turismo y seguir trabajando en el parque. √Čl me ense√Ī√≥ una vez m√°s la importancia de ser paciente y estar dispuesto a aprender de los dem√°s. Las apariencias enga√Īan y uno normalmente no esperar√≠a que un quincea√Īero t√≠mido fuera un experto naturalista. Pero siempre puedes aprender algo si est√°s dispuesto a escuchar.

Las palmeras y √°rboles identificadas por Samuel son:

Laurel Cordia aliodora. Palta laurel (no identificada). Pachubilla o caminante Socratea exorrhiza. Majo Euterpe oleracea. Tembe Bactris gasipaes. Ramoncilla Trichilia pallida.

A burning hunger June 24th, 2018 by

Towards the end of the dry season many families across the African savannas have exhausted their reserves of stored cereal crops. Vegetables are hard to come by in local markets. Bush meat is one way for rural people to supplement their meagre diet with protein during the well-named lean or hunger season. This is why development organisations have struggled for decades to curb the destructive practice of setting the bush on fire to hunt small wildlife.

One option to ensure some food and income during the lean season is to grow cashew and mango trees. But with increased labour costs and insecure markets, it is difficult for farmers to properly maintain their planted trees. Slashing the weedy and bushy undergrowth is often only done late during the flowering and fruiting season, by which time bush fires set by others may have spread into and destroyed entire plantations in no time.

Increasingly, development organisations are starting to realise that integrated farming systems and local value addition to food are the way forward. In a recently published video on the Access Agriculture video platform, the Beninese NGO DEDRAS neatly shows how growing groundnuts and soya beans in cashew plantations helps farmers produce a nutritious crop during the lean season, and thus discourage damaging bush fires. DEDRAS also made a training video with rural women on how to make cheese from soya, a good example of adding value.

In addition to tree crops, such as mango and cashew, farmer also manage other local species, such as n√©re (Parkia biglobosa) and the karit√© or shea nut tree (Vitellaria paradoxa). These wild indigenous trees, distincive features of the savanna, also provide fruits and nuts during the lean season. Ner√© and the shea nut tree have grown here for thousands of years and are relatively fire-resistant. Traditionally, n√©r√© seeds are dried, cooked and fermented to make “soumbala”, a local equivalent to bouillon cubes that brings taste to many dishes. But with an increased need for fuel wood, more n√©r√© are being cut down. While the fuel wood crisis has not received the attention it deserves, nutritionists have taken notice and have come up with a way to use fermented soya beans as a replacement for the local soumbala. This practice has been captured by the NGO AMEDD in Mali in a nice farmer training video, also hosted on the Access Agriculture video platform.

In an earlier blog, Jeff wrote about his experience with grasscutters in West Africa. Declining populations in the wild, along with the strong and continuing demand for meat, have inspired rural entrepreneurs to develop alternative sources. Across Africa one can witness how mainly women and youth have set up grasscutter, poultry, rabbit and other small livestock businesses.

The many training videos on small livestock, intercropping with legumes, and rural food processing offer viable alternatives to the hunting for bush meat. These enterprises may eventually prove more effective in reducing bush fires than lecturing rural people about their adverse environmental impacts. Positive solutions are always better at promoting behaviour change.

Families, land and videos in northern Uganda January 14th, 2018 by

Enyang Bua Philips grew up in the remote Lira District of northern Uganda, an area which is only now emerging from the poverty and violence brought about by the war with the Lord’s Resistance Army. Philips studied agriculture in High School. Then he went on to earn a diploma in marketing. In 2016 he was one of the co-founders of the Lango Family Farmers’ Association, which he organized to help farmers with land, marketing and technical issues. The association has four staff and 569 members, including 333 women.

I asked Philips recently how he was able to encourage so many women to join the association. It wasn’t hard, he explained. The women were already organized in village-based, self-help groups, and when he told them about the advantages of belonging to a larger association, all of these groups and their members signed up.

Land grabbers are a serious threat to family farms in Uganda, where rural people are easily swayed by the promise of money. The land grabbing companies take land, strip it of its fertility by growing export crops, and then abandon the community. Philips and his colleagues teach the groups that they have the right to reject the land grabbers, who come to the villages promising money. ‚ÄúThe land grabbers come in disguise,‚ÄĚ Philips explains to the groups, telling them ‚ÄúThere are no benefits, no money. (Not only do they make false promises), but when they go the land will be degraded and useless.‚ÄĚ

Another way to protect the land is by ensuring that family farmers can benefit from it.

In March 2017, Philips read an article in the Farming Matters online magazine about the videos hosted on www.accessagriculture.org. He downloaded over 20 videos and has shown 10 of them to the members of the association. He takes his laptop to the villages. There is seldom electricity, so he uses his battery to show the video to groups of about 30 people. He starts by introducing the video; afterwards he explains and discusses it with the members.

Philips recently shared the video on managed regeneration of forests with several villages. Many of the local people were amazed to see crops growing among the trees. ‚ÄúHere people cut down all of the trees before planting a garden,‚ÄĚ Philips told me over the phone.

While some of the Ugandan farmers still doubt the wisdom of growing trees and crops together, other local people have started experimenting with the idea. In each community, the Association helps people set up a demonstration plot, where they can try out innovations shown on the videos.

The farmer groups loved the videos on maize, on striga biology, and the one on mucuna, or velvet bean, a hardy legume that can be planted as a cover crop to regenerate degraded soils (such as the ones stripped by the land grabbers).

Mucuna seed can be hard to find in Northern Uganda, but these observant farmers quickly spotted wild mucuna growing on the edges of their fields. They are now gathering seed so they can plant it in damaged fields during the next rainy season, to see if they can bring some of their land back to life.

The internet is quickly spreading, but it will be a while before most farmers in Lira District are online. Meanwhile, a grassroots community organizer finds useful videos online, and shares them with groups of village farmers.
