Center for Food Safety’s Soil Solutions team attended the second week of the recent U.N. climate conference, COP22, in Marrakech, Morocco. In light of the rhetoric about pulling out of international climate agreements and rolling back domestic climate change programs, the growing global support for soil carbon restoration through regenerative, ecological agriculture was indeed a bright spot.
The first day was spent with the Women’s Earth & Climate Action Network (WECAN) who brought together women on the front lines of climate change from vulnerable communities around the world. Most came from countries like the Maldives that have done almost nothing to contribute to climate change but whose very survival is increasingly threatened. Their stories were humbling, and I was honored to address the group in order to make the connection between soil carbon and climate resilience. Rebuilding soil carbon offers an immediate avenue for action for rural people facing the mounting challenge of collecting food and water for their families.
The next day, we visited a women’s cooperative in the beautiful Ourika Valley of the Atlas Mountains where we saw olive orchards, almond saplings and calendula beds planted by indigenous Amazit or Berber women. A program of the High Atlas Foundation, the cooperative is improving livelihoods for women and increasing resilience to an unpredictable climate. Empowered by their successes, the women also have an ambitious tree planting campaign in the region’s schools.
The morning of the first consortium meeting for France’s “4 per 1000” initiative, we were extremely fortunate to interview the French Minister of Agriculture, Stéphane Le Foll. The initiative aims to demonstrate that agriculture, and agricultural soils in particular, can play a crucial role in improving food security and mitigating climate change. Launched last December at COP21, CFS was the first civil society organization to join the program. In addition to interviewing Minister Le Foll about his vision for the initiative, we were able to interview several of our “4 per 1000” partners. Be sure to look for these new interviews as part of our ongoing Dig Deeper series during the coming months.
Finally, in addition to participating in several other events sponsored by soil colleagues we had the honor of hearing Secretary John Kerry reaffirm the United States’ commitment to the Paris Climate Agreement he signed earlier this year. Kerry’s address was reassuring to our many allies around the world. While COP21 was about coming together in agreement, COP22 was about action. Now is not the time to disengage from the world on climate change, and CFS’ Soil Solutions team is proud to be helping to shape global policies that will determine humanity’s future.
Last week Britain’s Prince Charles convened “Climate Friendly Landscapes,” an international meeting to discuss a topic he believes is “at the heart of everything” – the prince was, of course, referring to healthy, fertile soil.
With the 22nd United Nations climate Conference of the Parties or “COP 22”starting next week in Marrakech, Morocco, it is exciting to see soil, an often overlooked, but essential natural resource, make global headlines.
Among those presenting at the London meeting were Professor Rattan Lal of Ohio State University, president elect of the International Union of Soil Sciences, and Eric Toensmeier, Yale University lecturer and author of “The Carbon Farming Solution.” Toensmeier, who shared insights strategies that drawdown atmospheric carbon including planting tropical tree staple crops, silvopasture (the practice of combining forestry and grazing) and multi-strata agroforestry systems, said “It was great to see finance (World Bank and more), government ministers, NGO leaders, farmers, and scientists all in one room focusing on climate mitigation and scaling up carbon-friendly practices.”
An agro-ecological, organic farmer for the past thirty years, Prince Charles praised Germany’s Bonn Challenge which advances the cause of forest landscape restoration. He also praised France’s 4 per 1000” initiative which seeks to increase the organic content and health of soils worldwide and vowed to advance similar soil-building targets in the United Kingdom. Formally introduced at COP 21 last December, “4 per 1000” has now been signed by 180 governments and institutions and more are expected to sign up at COP 22. CFS is proud to have been among the initial signatories and will be at the first meeting of civil society to plan the initiative’s governing structure.
Blessed with a Mediterrean climate, Morocco is one of the world’s most productive and agriculturally diverse countries; and agriculture, unlike other sectors of the global economy, has the potential to emit or sequester greenhouse gases. Those of us convening in Marrakech are tasked with building upon the historic COP 21 when 191 nations reached the Paris Agreement. We hope more governments, civil society organizations, scientists, and farmers’ organizations join France and the UK in setting targets to increase the carbon content of soil, an achievable task with global benefits. Here’s how Prince Charles summed up the opportunity:
“What a wonderfully positive difference it would make to the lives of farmers and rural communities right around the world – from the U.K. to Senegal, the U.S. to Argentina, from France to India, and from Brazil to the Middle East – if farmers and rural communities, who are the first to suffer from the rigors of a changing climate, as well as from the damage to the health, ecology and biodiversity of the natural environment upon which they (and we) wholly depend, could be properly rewarded for being good stewards of their land, including their soil carbon…”
Earlier this month, Center for Food Safety brought together its Soil Solutions program and its Hawai‘i office to host “Healthy Soils, Healthy Ranching” – a conference for ranchers from across the state of Hawaii at Puʻu O Hoku Ranch on the island of Molokai.
This conference brought together forward-looking ranchers with a variety of experts to share best practices, review emergent science on the role of soil health in climate change mitigation, and create a rancher-to-rancher network for future data monitoring and collaboration. Participants were welcomed to the beautiful ranch by Ashley Lukens, director of Hawai’i CFS. Soil Solutions program director, Diana Donlon brought attendees up to speed on the climate angle by outlining the direct connection between soil degradation and excess atmospheric carbon.
Johann Zietsman, a pioneer in holistic planned grazing from Zimbabwe who now consults with land managers around the world, made the long journey to meet with the ranchers. Although Zietsman doesn’t ranch on a tropical island, the group found his advice on animal health relevant to any ecosystem. David Johnson, a molecular biologist specializing in soil microbiology at New Mexico State University, spoke about the importance of maintaining thriving soil microbial communities. Johnson has developed a system he calls “biologically enhanced agriculture management” or “BEAM.” Johnson’s experiments using BEAM show a new direct correlation between improving fungal–bacterial ratios in soils and increasing the ability to capture, store and retain atmospheric C02 as new soil carbon.
Mark Thorne, a State Range Extension Specialist and Rebecca Ryals, a professor in the Department of Natural Resources and Environmental Management at University of Hawai‘i at Manoa contributed a wealth of knowledge about management practices both in Hawai‘i and on the mainland. Hawai’i’s ranchers face different challenges from their mainland peers. Ranching on an island comes with a special set of constraints that impact such things as stocking and destocking, storing forage (hay gets moldy!) and transportation (no interstate highway system). Additionally, the state controls considerable amounts of land that is leased for livestock production, most in the form of month-to-month revocable permits. Several of the ranchers mentioned this issue as one that needs to be addressed to incentivize the adoption of better grazing management practices.
By the end of the productive weekend, the ranchers had agreed on the importance of baseline carbon monitoring and plan to work with Ryals to set that in motion. They also agreed that the ecological and social benefits of well-managed ranching are an under-recognized story that bears telling:
Well-managed ranching landscapes help filter and store fresh-water resources; mitigate erosion that threatens sensitive reef habitat; are a tool for keeping invasive plant species in check while providing habitat for song birds; and contribute to food security and sovereignty, all the while preserving Hawai’i’s rich traditions and identity.

In bone-dry California we are counting the days until October when the rainy season should begin.
When wells run dry in the Central Valley, fires rage in Big Sur and pine forests in the Sierra Nevada die off, you can’t help but wonder where all the water has gone. But what if we asked a slightly different question: where should the water be?
To answer this it helps to know that soil hydrologists classify fresh water as either blue or green. According to Henry Lin, Professor of Hydropedology / Soil Hydrology at Penn State University,
“Blue water refers to water collected in rivers, lakes, wetlands and groundwater. Blue water is available for withdrawal before it evaporates or meets the ocean. Green water refers to water absorbed by soil and plants and is then released back into the air. Green water is unavailable for withdrawal.”
Nevertheless, it may be surprising to learn that what ends up as blue water represents only approximately 38.8 percent of total precipitation, whereas what ends up as green water represents the remaining approximately 61.1 percent of precipitation.
Although green water clearly represents the lion’s share of precipitation, as Professor Lin states, “green water is an often overlooked resource.”
Why do we fail to see the green water—the water that is stored in soils and consumed by plants?
Film-maker Deborah Koons Garcia provides one hypothesis. Koons Garcia, who wrote and directed Symphony of the Soil, an homage to Earth’s living soil system, points out that most people are “soil blind.”
If we “saw soil,” she says we would recognize that when it is healthy, soil acts like a giant sponge that absorbs water during floods and provides it to plants in times of drought. We would also “see” the difference between soils that have structure and soils that don’t. In order for soil to store water effectively it must have organic matter, or carbon. This carbon gives soil the structure necessary to carry out its filtering and holding functions. When rain falls on soils that are carbon deficient, the water isn’t absorbed into the soil sponge.
Instead, the rain sloughs off the ground’s surface, dragging valuable topsoil along with it. This is what is referred to as ineffective rainfall and it is how green water starts to go missing from the soil sponge.
The good news is that soil blindness can be easily cured by learning something about soil’s remarkable potential, and rainfall can be made more effective. The Natural Resources Conservation Service (NRCS) has determined that a one percent increase in organic matter (carbon) in the top six inches of soil increases its holding capacity by approximately 27,000 gallons of water per acre.
Increasing soil carbon can be done in a number of ways including cover-cropping, composting and planting deep-rooted perennials. The average farm size in California is 312 acres. Increasing the soil carbon content by one percent on just one farm (27,000 gallons x 312 acres) has the potential to yield an additional 8,424,000 gallons of green water. Multiply that by California’s 81,500 farms and you begin to grasp the transformative potential that increasing soil carbon by a mere one percent would have on the state’s green water supply.
“Worldwide,” says Lin, “nearly 90 percent of water consumed by croplands is green water making green water key to global food security and land use.”
Once we start actually seeing soil, we can realize that much of the water that has gone missing is of the green variety. The next step is to increase the organic matter on our fields so that when the rains finally come we’ll have forged the conditions to recreate the soil sponge.

Film short highlights the critical importance of soil health in protecting the environment
SAN FRANCISCO—Soil Solutions to Climate Problems, a short film highlighting the potential power of improving soil health to grow healthy food, store fresh water, and return carbon to the soil is now available in French. The new version of the film, made by the public-interest non-profit, Center for Food Safety, is available online today and will be shown in presentations next week in Lyon, Grenoble and Strasbourg and as part of Festival Zero Waste (June 30-July 2 in Paris) coordinated by “Zero Waste France.”
“People all over the world need to understand that healthy soil is vital to climate stability. We are delighted that our film will be reaching Europe’s growing zero waste community. Organic matter from cities and towns everywhere is a critical resource and must be utilized to help improve the health of our soils,” says Diana Donlon, Soil Solutions producer and Center for Food Safety’s soil program director.
Robert Reed, a zero waste specialist based in San Francisco, will be making his third trip to France as a volunteer assisting Zero Waste France in their mission to help communities across the country explore the importance of increasing recycling and composting. “Soil Solutions to Climate Problems is one of the most intelligent educational pieces I have ever seen. I encourage everyone to watch this brief film because it shows something very important – that improving soil health represents our best opportunity to protect the environment and try to slow climate change.”
The English version of the film, narrated by author Michael Pollan, had its first screening during the launch of the French Ministry of Agriculture’s “4 per 1000” initiative for food and climate security during the United Nations Climate Conference in Paris last December. Center for Food Safety made the piece to communicate an under-recognized opportunity to address the climate crisis – rebuilding soil carbon stocks globally.
The film is now being shown in a wide variety of settings including elementary schools in Finland, green film festivals in Berlin and San Francisco, as well as by community groups in four Southern African countries. In addition to French and Finnish the film is also available with Chinese and Spanish subtitles.

U.S. President Barack Obama and Chinese President Xi Jinping will mark Earth Day 2016 by signing the Paris Climate Agreement at an official ceremony at the United Nations headquarters in New York City.
Meanwhile, Center for Food Safety, a national nonprofit organization, celebrates the occasion by releasing a new version of its short film Soil Solutions to Climate Problems with Simplified Chinese subtitles. The four-minute film, which had its first screening at COP21 in December 2015, outlines the vast global opportunity to rebuild soil health as a win-win strategy to sequester excess atmospheric carbon. The video is narrated by well-known American food author Michael Pollan and highlights the French Ministry of Agriculture’s ambitious “4 per 1000” initiative for food and climate security.
By increasing the carbon content of their soils, the United States and China could improve their food, water and climate security, while making significant strides toward the greenhouse gas reduction targets set forth in the historic Paris agreement.
