Monkeys in the sacred forest May 31st, 2020 by

Of all the possible ways to save a primate species from extinction, the least expected is voodoo. It is known as vodun in Benin, West Africa, where Swiss ecologist Peter Neuenschwander began his conservation efforts.

I have written before how Peter first acquired, in 1995, a little group of red-bellied monkeys, a critically endangered species that lives only in the dwindling coastal forests of Benin. Later, Peter started to buy tracts of forest to keep the monkeys. At first, he kept them in cages. But after the monkeys began to mate, the half-grown babies would slip out of the cages and forage in the forest, where they were also fed on cucumbers and bananas, to make sure they got enough to eat.

Peter told me his story when I visited him at his Sanctuaire des Singes (Monkey Sanctuary) in the village of Drabo Gbo, near Cotonou, 12 years ago. Now he’s published a novel, based on his experience, in which he gives more details about how he slowly acquired his 14-hectare forest, buying small plots of about a hectare at a time.

Although Peter enjoyed his research in entomology, and loved living and working in Africa, he swore he would never buy land there. Or at least until a friend took him to Drabo Gbo, a small area near the research station where Peter worked. A large extended family owned a piece of land that had once been natural forest, but was now mainly planted with teak trees. A small area of sacred forest still remained, dominated by a massive cola tree. It was love at first sight. Peter arranged to buy the land with the cola tree, and an adjacent plot recently cleared for maize.

The sale helped the villagers of Drabo Gabo out of an impasse, for they had split into two groups, one of evangelical Christians and one of believers in vodun. The evangelicals wanted to cut down the forest and sell the wood. They also wanted to stop the vodun worshipers holding their rituals beneath the cola tree on moonless nights.

Peter bought the sacred forest from the evangelical faction, which held the title to the land. They got their money and Peter got his land. He then told the vodun group that they could continue to hold their rituals in the forest, but only if they would protect it.

Peter offered more than moral support to the vodun group. He joined in their sessions and, as he acquired more land, he was eventually initiated into two vodun groups, Zan-Gbeto, and Oro. In return, the Zan-Gbeto assigned a young man to be Peter’s guardian. Peter built a house on the deforested land, and with his guardian began to reforest the maize and fallow fields. Fortunately, the land had only recently been cleared from forest. Some trees grew up from the stumps left in the field. Other saplings sprouted from seeds that were still in the soil. Peter’s guardian would also bring in rare tree seedlings that he had found in neighbor’s fields.

As Peter describes in his book, it hasn’t always been easy. The villagers often ask him for cash to pay for school fees, funerals and medical expenses. He feels that he has to pay or they will turn on the forest, since they think that it would be better used for farming. There has also been violence, including a machete fight fueled by alcohol at a vodun meeting, and even murder.

Yet the villagers essentially held up their end of the bargain. The vodun men kept the hunters and woodcutters out of the forest. Peter could not have protected the forest by himself. There have been other benefits besides providing a home for the monkeys. By 2015 about half of the endangered plants in Benin were to be found in this sacred forest. Some animals, like the royal pythons, have become rare, but the red-bellied monkeys are reproducing. Peter has managed to pass his sanctuary forest on to the International Institute of Tropical Agriculture (IITA), where he still works on a voluntary basis. IITA will use the forest as a place to study insects, which are essential for biological pest control, which is Peter’s specialty.

The sacred forest is now recognized as a reference forest. Botanists can visit and see trees that they may have never seen before, because the forests that still harbor them are too remote.

Many northern scientists who work and live the tropics have done important research. Few have made a home for endangered monkeys in a sacred forest, and by doing so, saved both. It’s not a job for the faint of heart. Peter is nothing if not honest about his experiences. “There are times when I hate myself for being here, and detest the entire village.” But he also writes: “After years of travelling throughout Africa in a quest to improve sustainable farming, this attraction culminated in a boy’s dream come true: living in a real forest, tending rare plants, and raising endangered monkeys.”

Friendly germs April 5th, 2020 by

At a recent event in Cochabamba, just before Bolivia went into lockdown over coronavirus, I had a rare opportunity to see how to make products or inputs used in agroecological farming.

The organizers (the NGO AgroecologĂ­a y Fe) were well prepared. They had written recipes for the organic fertilizers and natural pesticides, an expert to explain what each product did and to show the practical steps. The materials for making the inputs were neatly laid out in a grassy meadow. We had plenty of space to build fires, mix materials such as cow dung with earth and water, and to stand and chat. Agronomist Freddy Vargas started by making bokashi, which extensionists have frequently demonstrated in Latin America for decades, especially among environmentally sensitive organizations.

Bokashi is sometimes described as fertilizer, but it is more than that; it is also a source of minerals and a culture of microorganisms. Freddy explained that for the past 25 years, ever since university, he has been making bokashi. He uses it on his own farm, and teaches it to farmers who want to bring their soil back to life.

Freddy mixes leaf litter and top soil from around the base of trees (known as sach’a wanu (“tree dung”) in Quechua. The tree dung contains naturally occurring bacteria and fungi that break down organic matter, add life to the soil and help control plant diseases. Freddy adds a few packets of bread yeast for good measure. As a growth medium for the microbes, he adds rice bran and rice husks, but any organic stuff would work. Next, raw sugar is dissolved in water, as food for the microorganisms. He also adds minerals: rock flour (ground stone) and “fosfito” (rock flour and bone flour, burned on a slow fire). The pile of ingredients is mixed with a shovel, made into a heap and covered with a plastic tarpaulin, to let it ferment. Every day or so it gets hot from fermentation, and has to be turned again. The bokashi will be ready in about two weeks, depending on the weather.

This elaborate procedure is why it has taken me some time to accept bokashi.  It seemed like so much work. Freddy explained that he adds bokashi to the surface of the soil on his farm, and over the years this has helped to improve the soil, to allow it to retain water. “We used to have to water our apple trees every two days, but now we only have to irrigate once a week,” he explained. His enthusiasm and clear evidence of benefits made me re-assess my previous skeptical view of bokashi.

Next, agronomist Basilio Caspa showed how to make biol, a liquid culture of friendly microbes. He mixed fresh cow dung, raw sugar and water with his hands, in a bucket, a demonstration that perplexes farmers. “How can an educated man like you mix cow dung with your hands?” But Basilio enjoys making things, and he is soon up to his elbows in the mixture before pouring it into a 200-liter barrel, and then filling it the rest of the way with water.

Basilio puts on a tight lid, to keep out the air, and installs a valve he bought for 2 pesos at the hardware store, to let out the methane that is released during the fermentation. The biol will be ready in about four weeks, to spray on crops as a fertilizer and to discourage disease (as the beneficial microorganisms control the pathogens).  Basilio has studied biol closely and wrote his thesis on it. He found that he could mix anything from half to two liters of biol into a 20 liter back pack sprayer. Higher concentrations worked best, but he always saw benefits whatever the dilution.

We also learned to brew a sulfur lime mix, an ancient pesticide. This is easy to make: sulfur and lime are simply boiled in water.

But do farmers actually use these products?

Then MarĂ­a Omonte, an agronomist with profound field experience, shared a doubt. With help from AgroecologĂ­a y Fe, she had taught farmers in Sik’imira, Cochabamba to make these inputs, and then helped the communities to try the inputs on their farms. “In Sik’imira, only one farmer had made bokashi, but many had made biol.” This seasoned group agreed. The farmers tended to accept biol more than bokashi, but they were even more interested in the brews that more closely resembled chemicals, such as sulfur lime, Bordeaux mix (a copper-based fungicide) and ash boiled with soap.

The group excitedly discussed the generally low adoption by farmers of these products. They suggested several reasons: first, the products with microbes are often made incorrectly, with poor results and so the farmers don’t want to make them again. Second, the farmers want immediate results, and when they don’t get them, they lose heart and abandon the idea. Besides, making biol and bokashi takes more time to prepare than agrochemicals, which is discouraging.

Bokashi and biol do improve the soil, otherwise, agronomists like Freddy would not keep using them on their own farms. But perhaps farmers demand inputs that are easier to use. The next step is to study which products farmers accept and which ones they reject. Why do they adopt some homemade inputs while resisting others? An agroecological technology, no matter how environmentally sound, still has to respond to users’ demands, for example, it must be low cost and easy to use. Formal studies will also help to show the benefits of minerals, microbes and organic matter on the soil’s structure and fertility.

MICROBIOS AMIGABLES

Por Jeff Bentley, 5 de abril del 2020

En un reciente congreso en Cochabamba, justo antes de que Bolivia entrara en cuarentena por el corona virus, tuve la rara oportunidad, como parte de un grupo pequeño, de ver cómo hacer insumos o productos para la agricultura agroecológica.

Los organizadores (la ONG Agroecología y Fe) estaban bien preparados con recetas escritas para los abonos y plaguicidas naturales, con un experto para cada insumo para explicar qué hacía cada producto y para mostrar los pasos prácticos. También tenían sus materiales debidamente preparados de antemano.

En un campo de pasto, teníamos mucho espacio para hacer hogueras, mezclar materiales como estiércol de vaca con tierra y agua, y para observar y charlar. El Ing. Freddy Vargas comenzó haciendo bocashi, que los extensionistas han demostrado muchas veces en América Latina durante varias décadas, especialmente entre las organizaciones sensibles al medio ambiente.

El bocashi se describe a veces como fertilizante, pero en realidad es más que abono orgánico; es tambiĂ©n una fuente de minerales, y microorganismos para el suelo.  Freddy explicĂł que desde que Ă©l estuvo en la universidad, durante los Ăşltimos 25 años, ha estado fabricando bocashi. Lo usa en su propia finca, y lo enseña a los agricultores que quieren devolver la vida a su suelo.

Freddy mezcla la hojarasca y con tierra que recoge debajo de los árboles (conocido como sach’a wanu, en quechua, “estiĂ©rcol de árbol”). El estiĂ©rcol de árbol contiene bacterias y hongos naturales que descomponen la materia orgánica, dan vida al suelo, y controlan las enfermedades de las plantas. Freddy agrega unos cuantos paquetes de levadura de pan por si acaso. Pone salvado de arroz y cascarilla de arroz como un medio de cultivos, pero podrĂ­a usar cualquier cosa orgánica. TambiĂ©n pone minerales: harina de roca (piedra molida) y fosfito (harina de roca y harina de hueso, quemado a fuego lento). Él añade chancaca disuelta en agua, como alimento para los microbios, luego da vuelta a todos los ingredientes con una pala, y se cubre con una lona, para dejarla fermentar. Más o menos cada dĂ­a el bocashi se calienta por la fermentaciĂłn, y de nuevo hay que darle vuelta a la mezcla. El bocashi estarĂ­a listo en unas dos semanas, segĂşn la temperatura ambiental.

Es un procedimiento exigente, que parece mucho trabajo, pero Freddy explicĂł que Ă©l agrega bocashi a la superficie del suelo en su finca para liberar los microorganismos en la tierra. A lo largo de los años esto ha ayudado a mejorar el suelo, para que retenga más humedad. “Antes tenĂ­amos que regar nuestros manzanos cada dos dĂ­as, pero ahora sĂłlo tenemos que regar una vez a la semana”, explicĂł. Su entusiasmo y la clara evidencia de los beneficios me ayudĂł a reevaluar mi opiniĂłn escĂ©ptica del bocashi.

A continuaciĂłn, el Ing. Basilio Caspa mostrĂł cĂłmo hacer biol, un cultivo lĂ­quido de microbios amistosos. En un balde, mezclĂł estiĂ©rcol fresco de vaca, chancaca y agua, explicando que cuando muestra a los agricultores cĂłmo mezclar el biol, se oponen. “ÂżCĂłmo es que un hombre educado como tĂş puede mezclar estiĂ©rcol de vaca con sus manos?” Pero a Basilio le gusta hacer cosas con las manos, y pronto está hasta los codos en la mezcla, antes de echarla en un barril de 200 litros, y luego llenarlo el resto con agua.

Basilio pone una tapa hermĂ©tica al turril, para que no entre el aire, e instala una válvula que comprĂł por 2 pesos en la ferreterĂ­a para dejar salir el metano que el biol liberará al fermentar. En un mes, el biol estará listo para fumigar los cultivos como fertilizante foliar y para evitar las enfermedades (por que los microorganismos benĂ©ficos controlan a los patĂłgenos).  En realidad, Basilio escribiĂł su tesis sobre el biol. EncontrĂł que podĂ­a mezclar desde medio litro de biol hasta 2 litros en una bomba de mochila de 20 litros, y que entre más biol que pone, más fuertes son las plantas. En base a eso, Ă©l recomiendo poner dos litros de biol para arriba en una bomba de 20 litros.

También aprendimos a preparar una mezcla de azufre y cal (caldo sulfocálcico), un antiguo plaguicida. Es fácil hacerlo; se hierve cal y azufre en agua.

ÂżPero los agricultores realmente usan estos productos?

Entonces MarĂ­a Omonte, una ingeniera agrĂłnoma con profunda experiencia de campo, compartiĂł una duda. Con la ayuda de AgroecologĂ­a y Fe, ella habĂ­a enseñado a los agricultores de Sik’imira, Cochabamba, a fabricar estos insumos y luego ayudĂł a las comunidades a probar los insumos en sus fincas. “En Sik’imira, solo un agricultor ha hecho bocashi, pero muchos han hecho biol”. Este experimentado grupo estuvo de acuerdo; asĂ­ era. Los agricultores tendĂ­an a aceptar el biol, más que el bocashi, pero más que eso, están interesados en los caldos que parecen más a los quĂ­micos, como el caldo sulfocálcico, el caldo bordelĂ©s (un fungicida cĂşprico) y el caldo ceniza (ceniza hervida con jabĂłn).

El grupo discutió animadamente la poca adopción que en general hacen los productores de estos preparados. Decían que hay varias razones: una es que no siempre se hace correctamente los mezclados con microbios, y los resultados no son buenos y los productores no quieren hacerlos nuevamente. Otra razón es que los campesinos quieren resultados inmediatos, y al no ver esto desconfían y lo dejan. Además, hacer biol y bocashi requiere mayor tiempo y esfuerzo en su preparación que los agroquímicos y eso los desmotiva.

El bocashi y el biol sí mejoran el suelo, si no fuera así, ingenieros como Freddy no los seguirían usando en su propia finca. Pero tal vez los agricultores demandan insumos más fáciles de hacer. El siguiente paso es hacer un estudio más al fondo para averiguar qué insumos aceptan los agricultores y cuáles no. ¿Por qué adoptan algunos insumos caseros y se resisten a usar otros? Una tecnología agroecológica, por más sana que sea, todavía tiene que responder a las demandas de los usuarios, por ejemplo, de tener bajo costo y ser fácil de hacer. Este tema también merece estudios formales sobre los efectos de los minerales, materia orgánica y microbios a la fertilidad y estructura del suelo.

A common ground March 8th, 2020 by

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

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

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

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

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

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

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

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

Note

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

Un terrain d’entente

Les agriculteurs ont besoin de nouvelles idĂ©es et les chercheurs ont besoin de donnĂ©es. Lorsque ces deux groupes professionnels se rencontrent dans le cadre d’une recherche collaborative ou participative, il est souvent difficile de savoir qui doit Ă©voluer dans quelle direction : les agriculteurs ont-ils besoin de connaĂ®tre les protocoles de recherche, de collecter et d’analyser systĂ©matiquement les donnĂ©es, ou les chercheurs ont-ils besoin de nouvelles idĂ©es de la part des agriculteurs pour orienter leur programme de recherche ?

Lorsque les projets financĂ©s par la Fondation McKnight en Afrique de l’Ouest se sont rĂ©cemment rencontrĂ©s Ă  Montpellier, en France, lors de la rĂ©union de comitĂ© de pratique (CoP) pour un Ă©change d’expĂ©riences, il Ă©tait intĂ©ressant de voir comment ce rĂ©seau s’est appropriĂ©, au fil du temps, certaines valeurs clĂ©s sur la recherche avec les agriculteurs en matière d’agroĂ©cologie comme moyen d’Ă©voluer vers un système alimentaire plus juste et plus Ă©quitable, soucieux des populations et de la planète.

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

En 2011, Aminou Ă©tait parmi les douze personnes que nous avons formĂ©es lors d’un atelier intensif de deux semaines sur la rĂ©alisation de vidĂ©os de formation de qualitĂ© paysan Ă  paysan. Depuis, Aminou utilise les vidĂ©os dans ses interactions avec le nombre croissant de membres de l’organisation, qui s’Ă©lève aujourd’hui Ă  environ 18 000 personnes. La sĂ©rie de 10 vidĂ©os sur la gestion intĂ©grĂ©e du striga et de la fertilitĂ© des sols, dĂ©veloppĂ©e avec l’ICRISAT et ses partenaires, a Ă©tĂ© traduite en Haoussa, ce qui rend l’outil idĂ©al pour susciter de vives discussions avec les communautĂ©s agricoles. Le striga est une mauvaise herbe parasite qui attache ses racines aux racines des cultures cĂ©rĂ©alières, privant ainsi la culture de l’eau et des nutriments dont elle a besoin.

“Lors d’une soirĂ©e oĂą nous avons montrĂ© les vidĂ©os”, raconte Aminou, “un des agriculteurs a pris la parole et a dit qu’il aimait les vidĂ©os, mais qu’ils avaient une autre technologie pour lutter contre le striga qui Ă©tait aussi efficace”. Aminou a Ă©coutĂ© attentivement comment les agriculteurs mĂ©langent leurs graines de millet avec la substance poudreuse qui se trouve autour des graines du nĂ©rĂ©, un arbre commun dans toute l’Afrique de l’Ouest. Lorsque les agriculteurs sèment du millet, la poudre de nĂ©rĂ© empĂŞche apparemment la germination des graines de striga dans le sol.

“C’est incroyable”, ai-je dit Ă  Aminou. “Ce serait gĂ©nial si vous pouviez en faire une vidĂ©o de formation.” Ă€ ce stade, il est apparu clairement que les agriculteurs et les chercheurs avaient dĂ©jĂ  commencĂ© Ă  interagir en tant qu’acteurs Ă©gaux. Aminou s’Ă©tait rapidement tournĂ© vers Salifou Nouhou Jangorzo, un professeur de l’UniversitĂ© de Maradi au Niger, qui s’Ă©tait joint Ă  notre discussion et a dĂ©clarĂ© “Nous devons en savoir plus sur cette pratique. Nous avons besoin de tous les dĂ©tails sur la façon dont les agriculteurs font cela “. Le professeur Salifou a d’abord eu l’air surpris ; il n’avait jamais entendu parler de cette pratique auparavant, mais après 5 minutes de discussion avec Aminou, il Ă©tait convaincu. Il s’avère qu’il prĂ©voit d’effectuer une enquĂŞte sur une technologie de dĂ©sherbage permettant d’Ă©conomiser la main-d’Ĺ“uvre et il a donc dĂ©cidĂ© sur-le-champ d’ajouter Ă  son enquĂŞte quelques questions sur la gestion de la striga avec la poudre de nĂ©rĂ©.

Les vidĂ©os de formation paysan Ă  paysan, comme celles de la sĂ©rie sur le striga, incitent les agriculteurs Ă  expĂ©rimenter de nouvelles idĂ©es. Elles donnent Ă©galement aux agriculteurs la confiance nĂ©cessaire pour partager ouvertement leurs expĂ©riences, leurs connaissances et leurs pratiques rĂ©elles de la vie. Grâce Ă  un rĂ©seau fonctionnel, ces idĂ©es peuvent ĂŞtre transmises aux chercheurs. Dans un rĂ©seau de recherche progressive et collaborative, la communication n’est pas un produit final en soi, comme l’a montrĂ© Aminou, mais elle alimente une vie d’apprentissage pour rendre l’agriculture plus rĂ©sistante, plus rentable et plus sensible aux besoins des agriculteurs.

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

Wicked seed January 5th, 2020 by

A recent story in The Economist (28 September 2019, page 18) highlights the low maize yields in Africa, and urges for greater use of hybrid maize seed. The Economist also has harsh words for NGOs: “African governments have mostly ignored the arguments from some charities, that old-fashioned farming is best and that wicked, profit-seeking seed firms should be barred.”

This caricature is misleading in two ways: many NGOs promote modern seed; and seed companies have more serious enemies than any “charity”.

Cassava is a big staple food in Africa, like maize. Unlike maize, which is planted using true seed, cassava is propagated with stem cuttings. Seed companies rarely sell stems or other vegetative planting material, even for major crops, other than potato. This is mainly for practical reasons; cuttings, vines and roots are bulky, and perishable. Farmers usually trade for cassava stems, get them from friends for free, or buy them from producers or traders.

Donor-funded projects, such as UPOCA and the Great Lakes Cassava Initiative, have also played an important part in making cassava planting material available, worked closely with NGOs to distribute the stems of new, disease-resistant varieties of cassava to farmers in various African countries. This progressive and modern system is neither old-fashioned nor wicked.

It’s not just cassava where such initiatives have helped make planting material available.  In Kenya, public research, like the 3G Seed Strategy, supported the production of high-quality seed potatoes (not true seed, but the small tubers that farmers plant). The project purposefully channeled the production and sale of the little seed potatoes through private companies and commercial farms, to promote sustainable business.

The real enemies of private seed companies include crooks who sell fake seed. To its credit, The Economist did mention counterfeit seed as a problem, but it is worse than the newspaper let on. In a visit to Premier Seed, a Nigerian company, I was impressed by their expertise and competence. They had a professional plant breeder, a tidy lab growing maize seedlings in rows of dishes, and an orderly warehouse stacked with bags of seed. I never heard Premier or other Nigerian seed enterprises complain about NGOs or “charities”.  The real problem was counterfeit seed. Criminals would buy cheap maize grain in the market, dye it to make it look like treated seed, and package it in bags printed to look like those of a real company. Farmers only realized they’d been sold a dud at harvest time. Counterfeit seed smeared the good name of the legitimate companies, whose packaging had been copied.

Life is difficult for seed companies trying to survive, especially the smaller ones. Even when the Nigerian government buys large amounts of seed from private companies to distribute to smallholders, as it does from time to time, there’s a twist. The government can be slow to pay its bills, with the result that a small company’s capital cash flow is blocked and capital is tied up for a year or more. Bigger firms with deeper pockets can more easily wait to be paid.

Few NGOs argue that old-fashioned farming is best. Most promote a sensible blend of tradition and innovation in agricultural practices and respect the pioneering.

There is a reason why seed companies may be seen as wicked. As Paul and colleagues recently explained in two videos (one from Guatemala and one from Malawi), some seed laws threaten farmers’ right to use their own seed.

African seed enterprises do have real problems, but “charities” are not among them. Governments should help national seed companies by arresting the fake seed sellers, and paying for seed on time. Farmers have a right to keep their own seed, but they need modern seed as well. NGOs and research centers often work together to provide such seed, especially for crops that private companies ignore.

The problem with water hyacinth November 17th, 2019 by

The Pantanal wetland, shared by Bolivia and Brazil, is the size of a small sea. In the Pantanal it rains for six months, followed by a half year drought. During the rainy season the rivers overflow their banks, creating a seemingly endless sheet of shallow water reaching to the horizon. In the dry season the water retreats to the river courses. There are few trees in the Pantanal, but there are dense stands of a delicate-looking purple flower, the water hyacinth.

In the twentieth century, gardeners innocently spread the water hyacinth to Asia, Africa and elsewhere. Water hyacinth has striking blue flowers and was used to adorn ornamental fountains. But it escaped and was soon clogging lakes, ponds and municipal water supplies.

Water hyacinth is such a survivor that you can drain ponds, let the plants dry out and burn them – then watch them grow again when the pond is refilled. It’s not surprising that control options are limited, particularly in open water, such as lakes and rivers.

The plants can be hand removed, by people willing to do heavy labor in the mud, cutting and dragging water hyacinth to the shore. Even this drudgery only works if you repeat it every year.

When the water hyacinth is removed, people tend to leave it in heaps at the edge of the water, where it is unsightly and gets in the way.

I recently saw another solution for water hyacinth in Benin, in West Africa. At Songhai, a training center in Porto Novo, they harvest water hyacinth, chop it, mix it with manure and use it to make methane (biogas) for cooking. Songhai also keeps a large tank of methane to run an electrical generator when the power is out.

Making biogas isn’t for everyone, as we saw in a previous blog. The Moreno family in Peru has trained people for years to make biogas from guinea pig manure, but few if any of the trainees later made biogas at home. For this to happen you need to buy equipment, provide labor, and pay close attention to managing the microorganisms that ferment the organic matter and give off the gas.

I liked the Songhai method because they don’t just remove the water hyacinth. They treat it like raw material and they make something with it.  But I wondered if using it to make biogas was profitable. A more detailed study is needed to gauge its potential to make money. The Songhai solution has one key advantage: the water hyacinth does not need to be dried, a plus because the big heaps of flesh plants hold retain a lot of water.

Water hyacinth is a water thief in some of the thirstier parts of the world. Finding uses for it may help to defray the costs of weeding it out.
