Argonauts Against the Desert

Are Berber women in Morocco’s argan groves holding back the spreading Sahara by producing a first-world luxury?

 

 


Green Stick Note: The following is a article from The Globalist (www.theglobalist.com) on how community cooperatives can restore ancient agricultural practices and thereby help to heal the environment. This is a story of Berber women in Morocco who are bringing new life and economic purpose to the native argan tree (Argania spinosa).
 By John Mathews
Everyone knows that the world’s deserts — from the Sahara to the Gobi — are spreading their fingers of sand. The desert expands as lands are over-grazed and over-tilled. Trees are clear-felled for timber. The loss of vegetation and drought drives the process. The Sahara is expanding south at a rate of 48 km per year, as once-fertile lands become arid. 
But there is a good news story to set against this dreary narrative. In Morocco, there are strong counter-moves to stop the desert at the Atlas Mountains (see map). The story involves a native tree, the argan, but also the Berber women of the Atlas. They are organizing to save the tree, and their livelihoods, through village-based women’s cooperatives. 
For centuries, the Berber tribes of southwest Morocco have lived in villages with their crops, their herds of sheep and goats — and their argan trees. These semi-desert, spiky bush-like trees have deep roots and the capacity to survive even in the harshest conditions. They also provided villagers over those centuries with critical resources — fuel for cooking and heating, timber for building, fodder for goats and cattle — and oil, extracted laboriously from the dried fruits of the tree. 
Then Europe intervened. When the properties of argan oil were discovered by European chemists, a new industry sprang up. Argan oil was soon exploited both for cosmetic purposes (anti-aging, anti-wrinkling) and culinary uses (nutty tasting oil for cooking and salads). Argan oil became the most expensive table oil on the planet. And an argan boom was created in Morocco. 
Unlike past European interventions, though, this one was fortuitous. For through this process, unfolding in the 1980s and ’90s, the destruction of argan groves in Morocco was actually slowed. Reforestation programs have been started in an attempt to reverse the process. In effect, argan oil established a new line of defense against encroaching desertification with renewed support for argan groves. The Atlas Mountains, with their argan tree cover, now stand as the only protection against the encroaching Sahara.
 The argan oil phenomenon has three aspects that make it of global interest.
  • Its ecological properties stand as shield against desertification.
  • Its economic potential earns revenues for Berber communities and exports for Morocco.
  • Its social dimension is that much of the argan oil phenomenon has been driven by new women’s cooperatives. This gives them a source of independence and balancing gender roles in a largely Islamic country.
Ecological: The Moroccan argan groves cover an area of approximately one million hectares (2.47 million acres) in the country’s southwest, between the Atlas Mountains and the Atlantic coast.

It is a precious ecological resource — as recognized by UNESCO in granting it “Man and Biosphere Reserve” status in 1998. The argan tree, with its deep roots and capacity to withstand arid conditions, is indigenous to Morocco and provides an ideal buffer against desertification. It binds the soil and provides shelter for many other rural activities.
Without it, the Sahara would already have advanced beyond the Atlas Mountains to approach the Atlantic and Mediterranean coasts. This would have had devastating results for the countries concerned and the regional climate. Instead there is a light covering of argan trees across the Moroccan landscape today. But it is one that desperately needs to be strengthened — if desertification is to be stopped and (even) reversed.

Economic: Morocco’s argan grove was almost destroyed by willful deforestation. This was driven largely by pursuit of wood for fuel by fast-growing cities like Casablanca. It was the developed world’s (re)discovery of the argan nut’s wonderful properties that provided an alternative economic resource, in addition to destructive use of the tree for its wood.
The nut and its oil had been in traditional use for centuries, but it was only after its properties were further developed by European and Moroccan scientists that its distinctive, pure, nutty flavor and properties became known to a global market.

Today, argan oil is one of the world’s most expensive, selling wholesale for €28 ($36) per liter. In retail markets such as European cosmetic shops the price can reach several hundred euros per liter. It is prized as culinary oil in Japanese, European and New York restaurants for its nutty, fresh flavor. But as an indigenous tree its productivity is limited. As much as 30kg of nuts are needed to produce one liter of oil. A single argan tree can produce only about one liter of oil per season — compared with 50 liters of oil from an olive tree. That explains the high price.
Social: The business of harvesting, processing and marketing the argan fruit and oil is almost entirely an activity of Berber village women. They increasingly organize themselves into women’s village cooperatives in order to have some extra market clout. Traditionally the women would perform these tasks in isolated households. Berber men would take the extra oil (beyond that needed for daily living) to market.
 Now increasingly, due to sustained efforts by NGOs and by village women themselves, the activities are dominated by women as a group, who increasingly control revenues from the sale of the cosmetic and edible versions of the argan oil. In a deeply conservative Islamic culture, this is no mean feat. In an eco-tour in the Atlas Mountains undertaken in April 2013, I met some of these women’s coop members.

Of course, the benefits of argan oil are not fairly distributed. The retailers and intermediaries still pocket most of the funds generated. Only a small amount flows back to the village women. But the women’s coops are directly targeting this issue and are raising their share of the total revenues generated by the value chain as a result. There are several NGOs working with the women’s coops to help drive this process.

Industry associations have been created expressly to give the women a collective voice in maintaining quality control and their own employment possibilities, as well as facilitating access to the wider market. Such organizations include the Groupements d’Interets Economiques (e.g., the Taroudannt GIE), as well as the National Association of Argan Cooperatives (ANCA) and theUnion of Women’s Argan Cooperatives (UCFA), utilizing brands such as “Argan d’or.”
However, the gains women have made are precarious and could be undone by their own success. Fundamentally, it is the women organized in their cooperatives in Morocco, bringing argan oil to the world and generating alternative economic uses for the argan tree, who constitute the front line in halting the further northward spread of the Sahara in Morocco. Their efforts are bearing fruit in every sense of the term. It is time that the rest of the world recognized this fundamental contribution and rewarded them appropriately.

Fungi May Be Able to Replace Plastics

Fungi, with the exception of shitake and certain other mushrooms, tend to be something we associate with moldy bread or dank-smelling mildew. But they really deserve more respect. Fungi have fantastic capabilities and can be grown, under certain circumstances, in almost any shape and be totally biodegradable. And, if this weren't enough, they might have the potential to replace plastics one day. The secret is in the mycelia.
 
Union College Biology Professor Steve Horton likens this mostly underground portion of fungi (the mushrooms that pop up are the reproductive structures) to a tiny biological chain of tubular cells.
"It's this linked chain of cells that's able to communicate with the outside world, to sense what's there in terms of food and light and moisture," he said. "Mycelia can take in nutrients from available organic materials like wood and use them as food, and the fungus is able to grow as a result."
"When you think of fungi and their mycelia, their function -- ecologically -- is really vital in degrading and breaking things down," Horton added. "Without fungi, and bacteria, we'd be I don't know how many meters deep in waste, both plant matter and animal tissue."
 
Looking something like extremely delicate, white dental floss, mycelia grow in, through and around just about any organic substrate. Whether it's leaves or mulch, mycelia digest these natural materials and can also bind everything together in a cohesive mat. And these mats can be grown in molds, such as those that might make a packing carton.
 
Ecovative Design, in Green Island, N.Y., is harnessing this particular mycological power and is being helped by Horton, and another Union researcher, Ronald Bucinell, associate professor of mechanical engineering.
 
Ecovative uses several species of fungi to manufacture environmentally-friendly products. The process starts with farming byproducts, like cotton gin waste; seed hulls from rice, buckwheat and oats; hemp or other plant materials. These are sterilized, mixed with nutrients and chilled. Then the mycelia spawn are added and are so good at proliferating that every cubic inch of material soon contains millions of tiny fungal fibers.
 
This compact matrix is then grown in a mold the shape of whatever item Ecovative is making. Once the desired texture, rigidity and other characteristics of the product are achieved, it's popped from its mold and heated and dried to kill the mycelia and stop its growth.
 
The all-natural products, the creation of which can take less than 5 days, have no allergy concerns and are completely non-toxic. More impressive is the fact that they're also impervious to fire (to a point), and just as water resistant as Styrofoam, but they won't sit around taking up space in a landfill. They are also more UV-stable than foam since they are not petrochemical-based, and won't emit volatile organic compounds. When exposed to the right microbes, they will break down in 180 days in any landfill or backyard.
 
Mycelium is comparatively inexpensive too as it can grow on farm waste that can't be fed to animals or burned for fuel. Better yet, the fungi can be propagated without sunlight or much human oversight in simple trays at room temperature -- no immense greenhouses with costly temperature-control systems needed. It also means a smaller carbon footprint and Ecovative is hoping to the point where they can displace all plastics and foams in the market.
 
"We manipulate one strain in various ways to see if we can make versions of the fungus to suit certain applications the company has in mind," Horton said. "For example, it might be helpful if Ecovative has certain versions that grow faster."
 
Associate Professor of Mechanical Engineering Ronald Bucinell and his students also offer critical support to Ecovative's research and development pipeline. Bucinell's particular expertise is in experimental mechanics and the mechanics of reinforced materials and is tasked with seeing how strong sample material is under different parameters. This includes determining whether mycelia bind better to one plant material or another; and does the way it's treated -- with heat or something else -- make it stronger or weaker.
 
"This is a brand new field in materials, and collaboration allows us to learn a lot, and quickly," McIntyre continued. "That's really important when you're trying to replace plastics."
