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.

Increased Carbon Dioxide May Lead to Greener Deserts


But researchers warn that CO2 fertilization could also result in other environmental shifts.

Increased levels of atmospheric carbon dioxide may have contributed to a gradual greening of some desert regions over the past 30 years, a process that will continue, according to a new study. But the authors warn that this "CO2 fertilization effect" could also have consequences for native plants and the wildlife that depends on them.

The study, published May 15 in the journal Geophysical Research Letters, was conducted by researchers from the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australian National University and the Australian Research Council Centre of Excellence for Climate System Science.

The researchers went into this project knowing that satellite data collected since the 1980s has shown a worldwide increase in green foliage. Scientists around the world have theorized that this may have been a result of increased levels of CO2, a theory this new study supports. The authors of this new study looked at desert areas on four continents — where increases in vegetation would be easier to see and quantify — and created a mathematical model to calculate how they might have been affected by CO2 fertilization.

With those calculations in hand, they then compared their predications to satellite imagery data from 1982 to 2010. Knowing that CO2 levels have increased 14% during that period, the researchers calculated that desert foliage would have increased from 5-10% during that 28-year period. The satellite data revealed that they average increase in foliage during that time was 11% (a number that was adjusted for short-term precipitation changes). The researchers call this correlation "strong support for our hypothesis," although it is not conclusive proof.

"Lots of papers have shown an average increase in vegetation across the globe, and there is a lot of speculation about what's causing that," lead author Randall Donohue of CSIRO said in a news release about the study. "Up until this point, they've linked the greening to fairly obvious climatic variables, such as a rise in temperature where it is normally cold or a rise in rainfall where it is normally dry. Lots of those papers speculated about the CO2 effect, but it has been very difficult to prove."

The direct link of this greening to CO2 has remained a theory for because, as Donohue explained to NBC News, "There are so many processes occurring simultaneously that affect plant behavior, it is very difficult to determine which process is responsible for any given change."

 The researchers warn that CO2 fertilization could have negative effects for native plants in these desert regions. "Trees are re-invading grass lands, and this could quite possibly be related to the CO2 effect," Donohue said. "Long-lived woody plants are deep rooted and are likely to benefit more than grasses from an increase in CO2." Increased tree levels in arid regions could, meanwhile, increase the threat of forest fires.

Donohue said the effect of increased carbon dioxide levels on plants should be a greater focus of global study. "It needs to be considered as an important piece of the overall global-change puzzle that we are still trying to figure out," he told NBC.
