Conservation Agriculture and Quality Food Products

August 8, 2013

After my long afternoon with TAN-EDAPS and an emphasis on small-scale organic production, I was excited and eager to hear another side of the story.  The next day I had made an appointment to speak with the production manager of an Arusha-based company called Quality Food Products.  They export safflower oil to nutritional product and food companies worldwide.  Safflower is an herbaceous, thistle-like annual plant native to arid environments with a long dry season and short rains.  It is often cultivated commercially for oil extraction from the seeds.  The top producers include India, US, Mexico, Ethiopia, Kazakstan, China, Arab countries, Argentina, Australia, and also Tanzania.  QFP provides high-tech, zero tillage planters to small farmers as an entrepreneurship strategy.  No till/low till/conservation farming aims to increase and conserve water content, organic matter, and nutrients in soil, as well as reduce erosion.  It has the potential to be more profitable because it reduces labor needs, fuel costs, irrigation, machinery costs, and has a potential for increased carbon sequestration.  However, zero till also requires specialized drill seeding equipment for minimal soil disturbance.  A critique of no till is that it may lead to increased chemical use, since glyphosate (e.g. Round Up) herbicide is sprayed to reduce weeds in seed bed preparation in lieu of tillage (which would normally aerate the soil and reduce weeds), as well as reduced incorporation of nutrients from fertilizers and crop residues.  However, there are alternatives to applying broad-spectrum herbicide in bed preparation such as planting winter cover crops and also using cardboard on the fields.  QFP started four years ago and since then, it has been giving small farmers access to modern agricultural technologies at a “reasonable rate,” in addition to organizational and technical guidance.  Their products include safflower oil, mung beans, chickpeas, rice, and wheat.  They are using “sustainable agricultural methods” and offer “the best supply chain” for farmers.  On their website, they are good about covering sustainability as we know it, with sections on people, planet, and profit.  For people, they claim to improve food security by ensuring that farmers are also growing traditional crops and vegetables for home use alongside the cash crops.  QFP is also assisting with increased income from the cash crops, which have a higher market appeal and they can get sales from the surplus.  They are also assisting farmers by reducing their workload through the technologies, freeing up time for other income generating activities.  For the planet section, QFP is reducing soil erosion through no till and helping to mitigate deforestation as farmers can now continue to plant on the same land for longer instead of slash and burn from one plot to the next.  For profit, QFP initially invests in the know-how, seeding, and machinery – farmers just have to provide the land (through a land tenure agreement and proof of ownership from the village council).  Through this model, mechanized harvesting is required (combine harvester) for the large scale.  They are also ensuring good crop rotation between food and commercial crops for the farmers.  Their system is one of “barter trade,” in which the safflower seed pays for the zero-till equipment, which farmers first hire on credit.  QFP provides rural service stations and assists with the zero till equipment using credit and for risk management, they split the cost in half with the farmer.  Some of the challenges they’ve faced include cattle grazing in cultivated fields (will lead to soil compaction and removal of crop residues), so they are working with communities to educate on the importance of separating arable land from grazing land.  Secondly, they are dealing with the issue of farm size threshold, meaning that often farms are too small such that they cannot mechanize or grow cash crops commercially; thus, QFP is encouraging farmers to loan idle land to neighbors to increase acreage.  In terms of land tenure, which is a bit of a sticky subject in Tanzania because the government technically owns all land and farmers just have communal land ownership through the village; so QFP is working with village governments to increase transparency and reduce confusion.  Another challenge is the risk aversion factor.  Farmers may want to conserve natural resources and adopt new technologies, but oftentimes it is expensive and risky.  QFP minimizes financial risk by providing all the equipment and for risk reduction, farmers don’t need to provide initial capital and can pay back the investment after harvesting.   A final challenge is related to unknown technologies, which can lead to further doubt and uncertainty.  QFP aims to overcome this by building trusting relationships with the farmers, discussing in depth the technology and also incorporating traditional knowledge.  This was all the info I gained from the website and I was able to garner more during my lunch appointment with the production manager.  He informed me that they are “building capacity for ‘unconventional’ agriculture” and are aiming to diversify their crops too (away from just safflower).  Eventually, the hope is that QFP can step back and eventually just become a trader, such that the farmers would be self-sufficient in operating the zero-till machinery.  He elaborated on the field stations, which offer equipment and hire it out per acre for planting, harvesting etc.  The stations will monitor the loans and field managers will facilitate and actually operate the machinery, with the farmer providing the land and overseeing the process (eventually will learn and become self-sufficient).  Unfortunately, it can be a big expense to shift to no till and of the cost and roughly 30% goes to services including the equipment and labor with another 30% to the seed/diesel fuel/other inputs (unfortunately, I missed what the last third goes towards).  Right now, QFP is working with about 500-600 farmers in the regions of Arusha, Manyara, and Kondoa (some in groups and others individually).  They want to encourage farmers to group up so they can increase their accountability among themselves, as well as the efficiency, communication, and transparency.  In 2911, it was a major drought year and QFP (the trading company) had no crops to sell.  So they are looking to stabilize and reduce this risk by also working with farmers who have the ability to irrigate (right now, they are mainly working with farmers that have no irrigation infrastructure or available water source).  Apparently markets are not a problem because the farmers produce such a high quality product and because customers provide next year’s price now, this guarantees farmers a profit.  They are mainly exporting crude safflower oil to Italy, the Netherlands, Switzerland, and other European countries.  QFP buys the crop/row product from the farmers and then owns and operates a mill in Arusha, which allows them to export a value added product (rendering them competitive).  I asked about seeds, and they are using mainly open pollinated for beans and safflower, and holding back some from the best fields to reproduce their own seeds (QFP is licensed as a seed company as well).  For the sunflowers, however, they are importing hybrid seeds.  “Seed is important, but more important is the practice, e.g. timing, fertilizers use etc.” he said. The production manager acknowledged that they are relying on a lot more chemicals with zero till and that there isn’t a practical alternative for their large-scale production (though they are rotating crops and are careful with keeping out weed seeds).  He also said that planting with sunflower is best for weed control because if can shut out light if planted densely.  And because they are exporting to Europe, they need to comply with the strict export standards for pesticide residues, which forces farmers to communicate their practices exactly.  They have to use synthetic fertilizers and pesticides because of the volume and scale at which they are producing.  In terms of the business, QFP was originally grant funded as an innovative enterprise and now has company shareholders.  I asked them about the farmers themselves and more specifically the community entry process.  He said that their reputation attracts farmers and they have more than enough interested individuals, it’s just a matter of finding the most committed. Moreover, QFP develops relationships with farmers by first giving them seeds and then following up with their progress.  Neighbors and friends will also refer each other.  For individual farmers, the land holding ranges: 30 acres for a small farmer, 50 for a medium and 500-800 for a large farmer.  This was interesting because it is definitely the largest land holding I’ve examined in Tanzania (most of the farmers I talked to owned 5-10 acres at most).  In terms of yield and profit, they are aiming to net $50/acre per season (200 kg per acre, which is a relatively low yield) and farmers have a 50% margin, which is even better than the company.  QFP, however, is able to profit from the value-added and trading aspects of the operation.  Naturally, they are working mostly with men and only about 5% women (women tend to dominate small-scale subsistence agriculture), though he noted that women participate in field labor and bean sorting (yippee).  They are targeting small-scale farmers as beneficiaries and business partners because “it guarantees returns and there is a huge potential because there are millions of them.”  I’m always curious as to how private companies and NGOs are interacting with the government and QFP has had mixed experiences with agricultural extension officers.  Officers are present in each district, but because these farmers are operating a bit off the beaten path in areas that shouldn’t be very agriculturally productive, the interactions with the government are limited.  In the future, QFP hopes to offload old equipment to competent farmers to increase capacity building.  They also want to expand to all of Tanzania but like everyone, they are waiting for cash flow and looking for private equity and venture capitalists.

I was able to meet with another farmer/company owner who is pursuing a somewhat similar business and production model to QFP.  His name is Mick Dennis and he is an Australian who has been farming in Tanzania since 2003.  He used to be in the contract harvesting business for wheat, safflower, and barley, then due to poor yield, he got out of combine harvesting and started manufacturing zero till planters.  His business Field Masters Ltd. currently works with a cutting edge agricultural technology known as bio-exhaust emissions.  The inventor of the “Emissions Systems Technology,” Gary Lewis, is Canadian and has a company known as BioAgtive.  They are currently operating on more than 150 arms in Tanzania, Canada, Jamaica, USA, Australia, England, South Africa, Kazakstan, and Japan.  According to their website, it "recycles your agriculture internal combustion engine emissions into plant nutrients by cooling the exhaust down through our Bio-Agtive™ System (NCQ BA8010) which is designed to capture, cool, condition and inject your emissions safely into the soil with no back-pressure or melted houses.This is the “newest technology in agriculture today,” and it restores carbon and nitrogen balance in the soil, while minimizing fossil fuel and fertilizer inputs by recycling tractor emissions and turning it into plant nutrients.  More specifically, the technology involves taking tractor exhaust (which contains CO2, water, nitrous oxide, and oxidized organic matter), cooling it, mixing it with the seed, and planting it.  This all happens in real time as the planters move through the fields, increasing soil nutrients by injecting the exhaust back into the ground via tine openers.  They have wireless monitors on iphones, which can assess temperature and gas amounts.  According to Mick, the biochar/soot that comes from the exhaust is used to coat the seed, which serves as a natural fungicide and seed dressing.  This stimulates mychorizae and nitrogen-fixing bacteria.  When the seed goes into the soil with the exhaust gas, the leaf of the plant becomes positive charged, absorbing increased levels of CO2, which stimulates plant growth.  He told me that this technology does the opposite of what fertilizer does and in fact, fertilizers are actually counter productive because they trick plants into thinking they have nutrients by giving them a negative charge.  This was all a bit too chemical for my understanding and I think I’m going to have to read more about it, but it seems like a pretty revolutionary system.  He said that it mimics the natural chemical process of composting and also increases the water levels in the root zone, stimulating and optimizing natural processes.  This leads to longer roots (an increased root:shoot ratio) and thus better established plants, as well as higher nodulation on beans for increased nitrogen fixation.  The Emissions Systems Technology "enhances plant physiology," and as part of a zero till scheme, this system helps the soil retain moisture (he’s working in areas that depend on rain for irrigation).  And in these areas, the soil has a pH of 9, so theoretically, growth shouldn’t even be occurring (he got the land because no one else wanted it).  However, the emissions system technology is actually lowering the pH over time, render the soil more arable.  Right now, the kit is $40-50,000 depending on the size.  Field Masters Ltd. contracts out the equipment until local farmers learn how to operate it themselves (this BioAgtive scheme is only in its second year operating in Africa).  It can also be combined with roto-tillers and smaller power tillers – he’s in the midst of researching new models and prototypes to make it more accessible to a range of farmers.  The eventual goal is to create a 75 horse power tractor-design that could be mass produced for only $5-8,000.  Right now, they are hiring out the plow contract system for 35,000 tsh ($22 USD) per acre, which is the exact same amount it costs a farmer to regularly plow one acre (so they’re quite competitive).   According to Mick, “inorganic fertilizers function well for two years and then the nutrients start to decrease.  This technology is a long term investment in the soil health and it pays back.  It makes poor quality soil arable.”  He is producing sorghum and safflower, which he sells to local buyers (such as QFP), who then export the products.  He also grows maize and beans and is cultivating 2,500 acres between two farms.  Field Masters Ltd. is currently working with 300 farmers with a future target of 7,000: “the demand is there but there isn’t enough equipment or skilled labor.”  He employs 18 local Tanzanians and among them, they can plant 280 acres per day (using 400 L of fuel), “this is mind boggling to small farmers.”  And although conservation agriculture increases/retains soil moisture and nutrients, “we have to use chemicals, but we’re battling with climate change.”  This is an ongoing conflict it seems.  He uses OPV seeds, claiming that “improved OPVs are the best.  We want something sturdy, consistent, and medium yield.  We’re not looking for high input and high yield.  It’s too risky.  OPVs express their full genetics, unlike hybrids, and though we may look into hybrids in the future, we don’t know the full genetic makeup of the seed and thus, how it’s going to react to/resist pests and diseases.”  And similar to what the QFP production manager said, Mick noted that “soil is most important.  We don’t need GMOs or hybrids if you take care of your soil.  Crop rotation is important, keep livestock out of the fields, reduce tillage, decrease chemical usage, keep pH down, and dissolve salts with organic matter because glyphosate locks up minerals in the soil.”  He said that he started with zero tillage 10 years ago, but is now slowly introducing low till methods to decrease chemical usage.  “You have to adapt and change methods.  Every pass, we’re putting gas and nutrients back into the soil, so tilling isn’t that bad.  And carbonic acid gas contained in the exhaust is fundamental to plant growth.”  He noted that accountability in the agriculture system is crucial, “people have to change and reject indoctrination; we need a paradigm shift” (presumably referring to the perceived need for inorganic fertilizers).  He noted that “Young people in Tanzania want to move to town and open up a shop, not farm.  But there are young Tanzanian farmers and entrepreneurs who are amassing land and growing hybrid cash crops.  They will be the future [of Tanzanian agriculture].  But we need to reinvest money into farming and land.”  Mick also encouraged me to read up on carbonic acid and its role in agriculture.  After a quick google search, I came upon a New York Times article dated 1914 titled, “On the Application of Carbonic Acid in Soil.”  It seemed like a good place to start, since I wasn’t aware of its role in fertilizer.  According to the article, Liebig’s “Natural Laws of Husbandry” say that farmers shouldn’t feel like they need to add nitrogen to the soil because it’s already there, locked up, and just needs to be “activated” by a solvent.  “Water, with the cooperation of carbonic acid, decomposes the silicates and makes undissolved phosphates soluble and diffusible through the soil.”  One can add carbonic acid by adding humus through manure, though the author acknowledges the difficulties in dealing with large volumes.  Carbonic acid can also be artificially made and injected into the soil, which seems to be similar (if not exact) to what BioAgtive Emissions System Technology is doing.  During our brief interview, Mick’s girlfriend was there and noted, “fertilizer companies don’t like Mick.  They aren’t making money off of him and he’s going totally against their business.”  We should keep in mind that inorganic fertilizers were created following WWII when there was an abundance of nitrates available (and they needed to do something with them).  The gist of what they were saying is that farmers today are essentially brainwashed into thinking that they need synthetic fertilizers.  And when I asked about how Tanzania farmers are receiving the technology I was told that although many were at first bewildered, they have been overall receptive because they are coming at it with fresh eyes and untarnished views, whereas before they were just putting seeds into the ground somewhat mindlessly. 

This meeting, perhaps more than any other thus far, has made me ponder the tension inherent in my project.  This Emissions Systems Technology seems to genuinely embody the “modern technology” concept I proposed to research in a way that all of my other encounters have not.  Mostly, I seem to be experience appropriate technology – that which is simple, affordable, easy to use and maintain, small-scale and locally produced.  This technology, in contrast, is the exact opposite.  As it is a bit abstract and chemically complex, I am having difficulties wrapping my head around the concept, which Mick expressed so simply.  He emphasized evolution/survival of the fittest in agriculture and the importance of a creative entrepreneurial spirit in the younger generation of farmers, those people who are going to come in and replace their parents and grandparents, bringing with them a revolutionary wave of technological acceptance.  These notions are hopeful but also seemed to directly challenge that which I have been encouraged to believe throughout my time as an undergrad at Hamilton.  I.e. Slow Food values of looking to older generations and the importance of safeguarding the wisdom of elders, that traditional knowledge which has been so successful and paramount for centuries.  But has it been successful?  How do we measure success and sustainability?  The farmers I’ve met in Tanzania can barely afford a hand pump to irrigate their two acre fields.  Some want chemical inputs but can’t afford those either.  If this is how their parents “taught” them to farm, can we count their struggles as a success?  Or have we entered a new age where climate change (drought, erratic weather patterns etc.), depleted soil, land and water shortages, and chemicals rule?  Is this new context making old knowledge obsolete?  I don’t know.  I don’t think there is a clear or easy answer.  I don’t think recent trends could possibly negate indigenous wisdom entirely, as there seem to be basic farming practices that are reliable, age-old truisms such as crop rotation and applying animal manure.  But only some farmers I’ve talked to have been trained in intercropping, mulching, the use of homemade biopesticides, etc.  Did their parents know about these “best practices” and simply neglected to share with their children?  Or have open land and the freedom to slash/burn/and move on become so acceptable that actively and consciously restoring the nutrient content of existing soil is seemed unnecessary?  I don’t know.  Similar to the way I’ve been conceiving of a lot of issues recently (e.g. taking both a top down and bottom up approach are necessary), it seems that this may be a similar example, except involving old/new: that in the future, soil, climate, and water conditions are going to undoubtedly change (here they already have and as I read news headlines from around the world, Tanzania is not alone), and new methods of mitigation and adaptation will have to take place, at least to some degree.  These may exhibit the combination of “modern” technology and traditional wisdom – that precarious balance that seems like a contradictory and inaccessible space. 


Moreover, I still haven’t been able to come up with any solid thoughts about globalization versus localization of the food system.  My heart is telling me that local is the way to go.  That local production and consumption with shorter value chains and more transparency/accountability are the answer.  But I just read a study that undermined the commonsensical notion of food miles.  However, it is also important to note that we cannot reduce the local food movement to food miles along because “local” also benefits the local economy, produces better tasting/fresh/more nutritious food, and increases education among many factors.  Yet, signs here are pointing to exporting to foreign markets as one of the solutions to poverty for these small subsistence farmers.  That if only they could scale up and produce enough for the world market, then maybe they could become financially stable.  But the world market seems so risky with speculation of food prices, government subsidies, and infinite players in the value chain.  And the film The Economics of Happiness by Helena Norgberg-Hodge speaks to me, it really does (it emphasizes localization instead of globalization).  But after watching it for a second time at home with the family (I wanted to show them the region of Ladakh in northern India, my next destination after Tanzania), I began to question how much of it is founded on hard facts and numerical data.  I feel like I am being torn in two separate directions: indigenous wisdom or technological fix.  And I guess this is what the Watson is all about.
