The argan tree as a fundamental pillar for sustainable development.

The argan tree is typically a multipurpose tree that supports income generation, increases resilience and improves climate adaptation, playing a very important role in achieving the three dimensions of sustainable development - economic, social and environmental - at the local level.

The sustainable argan production sector contributes to the economic empowerment and financial inclusion of local communities, especially women living in rural areas. Cooperatives are instrumental in promoting local job opportunities and can play an important role in contributing to food security and in eradicating poverty.

For centuries, the argan tree has been a mainstay of the Berber and Arab-origin indigenous rural communities, which developed a specific culture and identity, sharing their traditional knowledge and skills through non-formal education, particularly the unique knowledge associated with the traditional production of argan oil by women.

The unique argan-based agro-forestry-pastoral system uses only locally adapted species and pastoralism activities and relies on traditional water management provided by the Matifiya - a rain water reservoir carved into rock, hence contributing to climate change mitigation and adaptation, and to the conservation of biodiversity.

"Despite the Central Appalachia ecosystem being historically famous as coal country, under this diverse broadleaf canopy lies a rich, biodiverse world of native plants helping to fill North America’s medicinal herb cabinet.

And it turns out that the very communities once reliant on the coalfields are now bringing this botanical diversity to the country.

“Many different Appalachian people, stretching from pre-colonization to today, have tended, harvested, sold, and used a vast number of forest botanicals like American ginseng, ramps, black cohosh, and goldenseal,” said Shannon Bell, Virginia Tech professor in the Dept. of Sociology. “These plants have long been integral to many Appalachians’ livelihoods and traditions.”

50% of the medicinal herbs, roots, and barks in the North American herbal supply chain are native to the Appalachian Mountains, and the bulk of these species are harvested or grown in Central Appalachia, which includes southern West Virginia, eastern Kentucky, far-southwest Virginia, and east Tennessee.

The United Plant Savers, a nonprofit with a focus on native medicinal plants and their habitats, has identified many of the most popular forest medicinals as species of concern due to their declining populations.

Along with the herbal supply chain being largely native to Appalachia, the herb gatherers themselves are also native [to Appalachia, not Native American specifically], but because processing into medicine and seasonings takes place outside the region, the majority of the profits from the industry do too.

In a press release on Bell’s superb research and advocacy work within Appalachia’s botanical communities, she refers back to the moment that her interest in the industry and the region sprouted; when like many of us, she was out in a nearby woods waiting out the pandemic.

“My family and I spent a lot of time in the woods behind our house during quarantine,” Bell said. “We observed the emergence of all the spring ephemerals in the forest understory – hepatica, spring beauty, bloodroot, trillium, mayapple. I came to appreciate the importance of the region’s botanical biodiversity more than ever, and realized I wanted to incorporate this new part of my life into my research.”

With co-investigator, John Munsell at VA Tech’s College of Natural Resources and Environment, Bell’s project sought to identify ways that Central Appalachian communities could retain more of the profits from the herbal industry while simultaneously ensuring that populations of at-risk forest botanicals not only survive, but thrive and expand in the region.

Bell conducted participant observation and interviews with wild harvesters and is currently working on a mail survey with local herb buyers. She also piloted a ginseng seed distribution program, and helped a wild harvester write a grant proposal to start a forest farm.

“Economic development in post-coal communities often focuses on other types of energy development, like fracking and natural gas pipelines, or on building prisons and landfills. Central Appalachia is one of the most biodiverse places on the planet. I think that placing a greater value on this biodiversity is key to promoting a more sustainable future for the region,” Bell told VA Tech press.

Armed with a planning grant of nearly half a million dollars, Bell and collaborators are specifically targeting forest farming as a way to achieve that sustainable future.

Finally, enlisting support from the nonprofit organization Appalachian Sustainable Development, Virginia Tech, the City of Norton, a sculpture artist team, and various forest botanicals practitioners in her rolodex, Bell organized the creation of a ‘living monument’ along Flag Rock Recreation Area in Norton, Virginia.

An interpretive trail, the monument tells the story of the historic uses that these wild botanicals had for the various societies that have inhabited Appalachia, and the contemporary value they still hold for people today."

Okay. So you know how industrial agriculture overuses synthetic fertilizers loaded with nitrogen to make up for the decades of soil degradation that intensive farming practices cause? So not only does a lot of this fertilizer end up as runoff in our waterways every time it rains, but while it's still on land it's messing with the surrounding ecology, particularly plants.

See, nitrogen normally exists primarily in our atmosphere, and most organisms can't absorb atmospheric nitrogen, even though it's a crucial nutrient. However, some soil bacteria are capable of drawing this nitrogen in and converting it to a form of ammonia accessible to plants. These bacteria can be found in little nodules of many plants' roots, and make the nitrogen available to their hosts in return for a nice safe place to live. When these nitrogen-fixing plants shed leaves or other parts, or die entirely, the nitrogen in their tissues is then released into the local ecosystem as they decay.

However, when we started supercharging farmland and gardens with tons of extra nitrogen through fertilizers, we threw off the entire nitrogen cycle. Plants native to a given ecosystem have evolved to tolerate a certain balance of nutrients, to include some that may be naturally scarce, and when the nutrient balance suddenly shifts significantly, it causes a lot of upset. With more nitrogen filtering through nearby ecosystems, and those downstream, nitrogen-fixing plants are suddenly losing their competitive edge, and are becoming less common in these places. Over time, they can become locally extinct, breaking whatever bonds they had with other species in the ecosystem, which often leads to even more ecological unraveling.

So you see, more fertilizer isn't always the answer. When engaging in habitat restoration efforts in many parts of the United States, it's important to work with the native soil instead of adding a lot of amendments. Those amendments can actually make it easier for invasive weeds to get a roothold because they often come from places with richer soil, or are simply more able to make the most of the excess nutrients to grow faster and out-compete native plants. Adding too much nitrogen, whether intentionally or as a byproduct of agriculture, makes it even tougher for native ecosystems to thrive in disturbed areas adjacent to farms. On the other hand, making sure your restoration site has native nitrogen-fixers and other pioneer plants helps set the stage for long-term success, while making conditions less favorable to nutrient-hungry invasive species.

We already had plenty of reason to curb the overuse of synthetic fertilizers; this study just adds another argument in that regard.

The surprising diversity of Pineapples (Ananas comosus).

The Active Pineapple Germplasm Bank (Pineapple AGB) of Embrapa Cassava & Fruits (Embrapa/ CNPMF) has more than 700 accessions under field conditions. As backups, there are copies kept in a greenhouse, with one or two plants per accession, cultivated in plastic pots with commercial substrate. An in vitro gene bank was established in 2003, and during the past few years, several studies have been carried out to improve the in vitro conservation protocol. Currently, about 60% of the AGB’s accessions are preserved by this protocol. Another conservation strategy used is cryopreservation of shoot tips and pollen grains, with well-defined methods. One of the most significant advances in the pineapple germplasm conservation has been the implementation of a quality control system, which enabled to define standard operation procedures (SOP) towards a more efficient and safer germplasm conservation.

In the tradition.

When you operate a small farm, stuff happens and ya gotta stop and repair, replace or recycle what’s broken. It’s not always easy and it definitely is a time commitment, however, it still remains a blessing because during the downtime, lessons are learned.

What have you fixed recently?

weird question, but do you know if regenerative agriculture is growing, and by what rate? it's important to me but looking for articles on my own can trigger a panic attack :[ no worries if not !

Hey! Thank you so much for asking. Honestly, agriculture and sustainable agriculture specifically are very close to my heart as well, so I was glad for the excuse to do some research :) 

Also, thank you for your patience, I know you sent this Ask a bit ago. It’s good that you’re listening to yourself and not going around searching for things that might cause you harm, so thanks again for reaching out!

So, what is regenerative agriculture? 

Regenerative agriculture is a way of farming that focuses on soil health. When soil is healthy, it produces more food and nutrition, stores more carbon and increases biodiversity – the variety of species. Healthy soil supports other water, land and air environments and ecosystems through natural processes including water drainage and pollination – the fertilization of plants.

Regenerative agriculture is a defining term for sustainability in our food system - while there is no one true definition of regenerative agriculture, the concept has been around for centuries, taking root in Indigenous growing practices. Regenerative approaches can bolster soil health and watershed health. They can also add to climate mitigation and potentially tie into regulatory or commercial incentives for a more sustainable diet. 

Regenerative farming methods include minimizing the ploughing of land. This keeps CO2 in the soil, improves its water absorbency and leaves vital fungal communities in the earth undisturbed.

Rotating crops to vary the types of crop planted improves biodiversity, while using animal manure and compost helps to return nutrients to the soil. 

Continuously grazing animals on the same piece of land can also degrade soil, explains the Regenerative agriculture in Europe report from the European Academies’ Science Advisory Council. So regenerative agriculture methods include moving grazing animals to different pastures.

How can it help?

Regenerative farming can improve crop yields – the volume of crops produced – by improving the health of soil and its ability to retain water, as well as reducing soil erosion. If regenerative farming was implemented in Africa, crop yields could rise 13% by 2040 and up to 40% in the future, according to a Regenerative Farming in Africa report by conservation organization the International Union for Conservation of Nature and the UN.

Regenerative farming can also reduce emissions from agriculture and turn the croplands and pastures, which cover up to 40% of Earth’s ice-free land area, into carbon sinks. These are environments that naturally absorb CO2 from the atmosphere, according to climate solutions organization Project Drawdown.

5 ways to scale regenerative agriculture:

1. Agree on common metrics for environmental outcomes. Today, there are many disparate efforts to define and measure environmental outcomes. We must move to a set of metrics adopted by the whole food industry, making it easier for farmers to adjust their practices and for positive changes to be rewarded. 2. Build farmers’ income from environmental outcomes such as carbon reduction and removal. We need a well-functioning market with a credible system of payments for environmental outcomes, trusted by buyers and sellers, that creates a new, durable, income stream for farmers. 3. Create mechanisms to share the cost of transition with farmers. Today, all the risk and cost sits with the farmers. 4. Ensure government policy enables and rewards farmers for transition. Too many government policies are in fact supporting the status quo of farming. The food sector must come together and work jointly with regulators to address this. 5. Develop new sourcing models to spread the cost of transition. We must move from sourcing models that take crops from anywhere to models that involve collaboration between off-takers from different sectors to take crops from areas converting to regenerative farming.

The rise of regenerative agriculture

In 2019, General Mills, the manufacturer of Cheerios, Yoplait and Annie’s Mac and Cheese (among other products), announced it would begin sourcing a portion of its corn, wheat, dairy and sugar from farmers who were engaged in regenerative agriculture practices and committed to advancing the practice of regenerative agriculture on one million acres of land by 2030. In early 2020, Whole Foods announced regenerative agriculture would be the No. 1 food trend and, in spite of the pandemic and the rapid growth of online shopping overshadowing the trend, business interest in the field still spiked by 138%. 

More recently, PepsiCo announced it was adopting regenerative agriculture practices among 7 million acres of its farmland. Cargill declared it intends to do the same on 10 million acres by 2030, and Walmart has committed to advancing the practice on 50 million acres. Other companies pursuing regenerative agriculture include Danone, Unilever, Hormel, Target and Land O’ Lakes.

According to Nielsen, 75% of millennials are altering their buying habits with the environment in mind. This sentiment, of course, does not always materialize into tangible actions on behalf of every consumer. However, it is clear from the actions of PepsiCo, General Mills, Walmart, Unilever and others that they believe consumers’ expectations of what is environmentally friendly are shifting and that they will soon be looking to purchase regeneratively-produced foods because of the many benefits they produce.

The next step in the transition to regenerative agriculture is certification. The goal is to create labeling that will allow the consumer to connect to the full suite of their values. Some companies are partnering with nonprofit conveners and certifiers. The Savory Institute is one such partner, convening producers and brands around regenerative agriculture and more holistic land management practices.

In 2020, the Savory Institute granted its first “Ecological OutCome Verification (EOV) seal to Epic’s latest high protein bars by certifying that its featured beef was raised with regenerative agriculture practices. 

The program was developed to let the land speak for itself by showing improvement through both leading and lagging functions such as plant diversity and water holding capacity. There are now thousands of products that have been Land to Market verified, with over 80 brand partnerships with companies such as Epic Provisions, Eileen Fisher and Applegate.  Daily Harvest is giving growers in that space three-year contracts as well as markets and price premiums for the transitional crop. It's focusing on that transitional organic process as a stepping stone toward a regenerative organic food system.

Daily Harvest’s Almond Project creates an alliance with the Savory Institute and a group of stakeholders - including Simple Mills and Cappello’s - to bring regenerative practices to almonds in the Central Valley of California.

These companies are working with Treehouse California Almonds, their shared almond supplier, to lead soil health research on 160 acres of farmland. Over five years, the Project will focus on measuring outcomes around the ecosystem and soil health of regenerative practices – comparing those side by side with neighboring conventional baselines.

“We need industry partnership; we need pre-competitive collaboration,” says Rebecca Gildiner, Director of Sustainability at Daily Harvest, of the Almond Project. “Sustainability cannot be competitive. We are all sharing suppliers, we are all sharing supply – rising tides truly lift all boats. The industry has to understand our responsibility in investing, where historically investments have disproportionately focused on yields with a sole focus of feeding the world. We know this has been critical in the past but it has overlooked other forms of capital, other than financial. We need to look towards experimenting in holistic systems that have other outcomes than yield and profit - instead of saying organic can’t feed the world, we have to invest in figuring out how organic can feed the world because it’s critical.”

In short!!!

Many articles are stating regenerative agriculture as a defining, and rising “buzz word” in the industry. It seems that consumers are becoming more and more aware and are demanding more sustainable approaches to agriculture. 

We, of course, have a way to go, but it seems from the data that I’ve gathered, that regenerative agriculture is, in fact, on the rise. Demand is rising, and many are working on ways to globalize those methods.

The Vile clings on to the edge of the Gower peninsula. Its fields are lined up like strips of carpet, together leading to the edge of the cliff that drops into the sea. Each one is tiny, around 1-2 acres. From the sky, they look like airport runways, although this comparison would have seemed nonsensical to those who tended them for most of their existence.

That is because the Vile is special: a working example of how much of Britain would have been farmed during the middle ages. Farmers have most likely been trying to tame this promontory since before the Norman conquest.

The fields have retained their old names, speaking to a long history of struggle against the soil. Stoneyland. Sandyland. Bramble Bush. Mounds of soil known as “baulks” separate one strip from the next. During the summer months, linseed and sweet clover paint the landscape with stripes of bright yellow and cotton-blue, recreating a scene that had occurred here for many of the last thousand summers. On the edge of the promontory were the hay meadows, almost ready to burst with pollen and petals.

The Vile is a rare example of the open-field system: a method of communal agriculture once practised across Europe. Under this system, each farmer attended his own strip of land, with the members of the village coming together more widely to cooperate and plan a healthy harvest. Remnants of such farms survive as shadows and undulations across the countryside today, showing the paths of ox-drawn ploughs as they moved up and down the fields, pushing the soil to the side as they went.

Farming is often seen as inimical to biodiversity, but these thin strips of land tell a more complex story. In the nooks and crannies of medieval farms, like the Vile, a wide range of plants and animals would have found the conditions they needed to survive. Ground-nesting birds could find cover and camouflage in the fields left fallow – something that was done every few years to allow the soil to recover. Baulks offered safe passage to small mammals as they navigated the cultivated land. The naturalist Colin Tubbs, in a survey of Hampshire, found that only a third of the county’s birds were adapted to woodland, with the rest preferring open, marsh, coastal or riverine habitats. Farmers “inherited the flora and fauna of the more ancient habitats, and indeed, in modifying the landscapes from which they derived, they may have increased plant and animal diversity,” he wrote.

May 10th as International Day of Argania.

This unique region, where argan trees have been cultivated for centuries combines agricultural biodiversity, resilient ecosystems and valuable cultural heritage. For that reason, it has gotten recognition and protection from various UN entities.

The United Nations Educational Scientific and Cultural Organization (UNESCO) designated in 1988 the endemic production area as the Arganeraie Biosphere Reserve. Also, all know-how concerning the argan tree was inscribed in 2014 on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity.

Moreover, in December 2018, FAO recognized the Argan-based agro-sylvo-pastoral system within the area of Ait Souab - Ait Mansour in Morocco as a Globally Important Agricultural Heritage System.

And lastly, in 2021, the United Nations General Assembly proclaimed 10 May the International Day of Argania. The resolution, submitted by Morocco, was co-sponsored by 113 member states of the United Nations and adopted by consensus.

The importance of agricultural biodiversity, Dalla Ragione says, can be explained with a very human metaphor—language. She likens biodiversity on a farm to expanding a vocabulary. Conventional agriculture, with its limited genetic range, relies on a narrow vocabulary: “Industrial agriculture created a few varieties that are very productive in very precise conditions, with a lot of chemicals and a lot of water. The new varieties may be bigger and have more consistent color, but they have very few genes—few words. Their genetic patrimony is very simple. If you present the right question, they can answer, because maybe they have four or five or maybe ten words. But if you present other questions—like drought or climate change or other situations—they have no words to answer. They can’t answer because they do not have enough genetic variability inside to answer these questions. Old varieties have a big vocabulary. They have many words to answer these new questions.”

Biodiversity loss in agriculture is a pressing threat to global food systems, reducing our ability to cope with climate change, environmental degradation, and nutritional challenges. Over the past century, about 75% of plant genetic diversity has been lost as farmers have shifted toward high-yielding, genetically uniform crops. Today, just nine plant species account for 66% of global crop production, with rice, wheat, and maize alone providing more than 50% of the world’s plant-derived calories. This reliance on a narrow set of crops undermines food system resilience, leaving us vulnerable to pests, diseases, and climate extremes. It has also created a monocultural vulnerability reminiscent of the Irish potato famine of the 1840s, when reliance on a single, genetically uniform crop led to catastrophic losses due to disease. Genetic diversity within and among species acts as a natural buffer against environmental changes. Different crop varieties respond differently to stressors, providing farmers with options to manage risks. When one crop fails, others can compensate, helping to safeguard harvests and livelihoods. However, as the diversity on our farms diminishes, farmers have fewer tools to adapt to the growing volatility brought on by climate change. Extreme weather events such as droughts, floods, and heat waves are becoming more severe, and monocultures are ill-equipped to withstand these shocks. The environmental impact of current agricultural practices further exacerbates biodiversity loss. Agriculture is responsible for about 90% of global deforestation and contributes substantially to habitat destruction, driving the extinction of countless species. Excessive use of inorganic fertilizers and pesticides pollutes soils and waterways, disrupting ecosystems and degrading essential natural services such as pollination and soil fertility. Soil degradation now affects one-third of the world’s soils. In sub-Saharan Africa, agriculture is responsible for 80% of soil degradation on farmland, leading to reduced plant diversity because only the few species that can tolerate poor soil conditions survive. Moreover, the heavy use of nitrogen fertilizers and livestock manure, particularly in regions such as Asia and Latin America, has disrupted natural nitrogen cycles, contributing to greenhouse gas emissions such as nitrous oxide and methane. These emissions not only drive climate change but also accelerate biodiversity loss by reducing the resilience and health of ecosystems. The decline of agricultural biodiversity also impacts human health. Diets worldwide have become increasingly homogeneous, dominated by a few staple crops that are energy-rich but nutrient-poor. Less than 200 species currently contribute to global food supplies, and this lack of variety has serious health consequences. Low dietary diversity is now a leading driver of diet-related deaths, with about 11 million premature deaths annually linked to unhealthy diets. The decline in biodiversity means that fewer nutrient-rich foods such as fruits, vegetables, nuts, and seeds are available, exacerbating malnutrition in all its forms, from undernutrition to obesity.

the Principles of Electrolysis Applied to Plant Nutrient Management

In 2022, during a trip to the United States, I discovered ionized alkaline water, which sparked my interest in nutrient electrolysis for plants. Although I do not have a background in chemistry or agriculture, my passion for sustainable farming led me to explore how electrolysis could enhance nutrient bioavailability. After several months of research, I am presenting a scientific review to synthesize current knowledge on this topic, evaluate the benefits of this technology in agriculture, and open new research perspectives on its use to address the challenges of sustainable agriculture.

The full review will be published online soon.
