In his budget released on January 10th, Governor Jerry Brown proposed on-going investments in climate smart agriculture programs, including the new Healthy Soils Program. The budget proposes to maintain current funding levels. However, there’s a catch. The funding will only become available if the legislature votes by two-thirds to extend the cap-and-trade program beyond the year 2020 when the program is set to expire. Why the catch?

The Soil Carbon Challenge digs directly into the ground with the farmers, ranchers, and landowners who can manage land to improve soil health. Peter Donovan, a leader in demonstrating the connection between land management practices and increased soil carbon, founded the Soil Carbon Challenge—“an international prize competition to see how fast land managers can turn atmospheric carbon into water-holding, fertility-enhancing soil organic matter.” Peter has established an approach to scientifically showing (not just telling) the nexus of appropriate land management, soils, and carbon sequestration.
When managed correctly, soil can become a “sink” for atmospheric carbon while also providing benefits such as increased water holding capacity, decreased erosion and runoff, and improved health, productivity, and resilience due to enhanced populations and diversity of soil microorganisms.
Peter believes in showing possibility by measuring change over time, and recognizing actual results. As such, The Soil Carbon Coalition supports “a different kind of science”, believing science is “based on shared evidence, open participation, specific locations and situations, and on learning to manage wholes more than parts.”
SACRAMENTO – Farmers and ranchers throughout California commend the legislature for its recent actions on climate change. The passage of key climate bills, alongside the appropriation of more than $65 million for climate-smart agriculture programs, will provide needed resources for farmers and ranchers to address a changing climate.
“Farmers have a lot at stake in a changing climate as our extreme drought reminds us,” said Tom Willey at T&D Willey Farms in Madera. “We experience the impacts of climate change on our farm every day. I commend the California legislature for continuing down the path of reducing greenhouse gas emissions and investing in the continued success of California agriculture.
When state legislators return to Sacramento this week, climate change will be at the top of their agenda. Still pending are finalization of the state’s climate change investments for the coming year and, most important, setting the road map for climate change policy in California beyond the year 2020.
For California agriculture, these decisions will impact whether or not there are resources available for the state’s farmers and ranchers to address a changing climate. Given the latest agriculture and climate change news of on-going drought impacts and rising temperatures hurting some crops, farmers and ranchers are weighing in, calling for support for programs like the Healthy Soils Initiative.
As we reported back in June, the FY 2016-17 budget was finalized without the legislature and Governor deciding how the state would invest billions in cap-and-trade revenues to reduce greenhouse gas emissions. Over $100 million in proposed funding is on the line for California farmers and ranchers to reduce water use and save on energy, improve soil management and store more carbon in agricultural soils, and reduce potent greenhouse gases like methane.

U.S. Department of Agriculture Initiative Gets Underway
During the U.S. Department of Agriculture’s Climate Month of May, Secretary Vilsack announced an additional $72.3 million for soil health investments to support the department’s 10 Building Blocks for Climate Smart Agriculture. Secretary Vilsack established the USDA climate change initiative just over a year ago in preparation for last year’s Paris Climate Conference. The initiative aims to increase agricultural practices that reduce greenhouse gas emissions and increase carbon sequestration in agriculture and forests.
This additional funding is being distributed through the Natural Resources Conservation Service’s (NRCS) Environmental Quality Incentives Program (EQIP), where each state will have the discretion to determine which Climate Change Building Blocks to focus their additional funds on. This is the first time EQIP funding has been explicitly allocated for climate-smart agriculture practices. California NRCS has received $4.3 million of this $72.3 million allocation.
California NRCS plans to fund agricultural management practices that address soil health, nitrogen management, grazing and pasture and private forest practices. All with an eye to increasing soil carbon and reducing greenhouse gas emissions. Farmers and ranchers, beginning this summer, can go into their NRCS District Office to find out more about how they may qualify for the new EQIP climate change funding. The application process is the same as regular EQIP.
A learning opportunity for CDFA’s Healthy Soils Initiative
The USDA funding for climate-smart agriculture comes at an important time for California. The state is considering a new Healthy Soils Initiative, also aimed at providing financial incentives for growers for management practices that reduce greenhouse gas emissions. The California Department of Food and Agriculture (CDFA) recently released its draft framework for the program. The upcoming California NRCS experience of distributing climate-related EQIP funds can help inform the CDFA initiative. More information can be found here.

Conservation Agriculture Systems Innovation Center
Soil health management is key to solving the climate change problems attributable to farming systems. One way to improve soil health is through adopting sustainable conservation systems that include conservation tillage (CT), cover cropping and other practices. CT describes a variety of cropping methods that involve leaving the previous year’s crop residue on top of the soil and planting the next crop right into it. To increase organic matter both above and below the soil surface, cover crops of a single or multiple plant species can also be grown between major crop rotations. Since crop residues are left on the soil surface and not tilled under, CT reduces the number of tractor passes needed, thereby cutting labor and fuel costs. Minimizing mechanical disturbance to the soil reduces erosion and runoff, increases water infiltration rate and retention, and increases carbon sequestration—all important strategies in climate change mitigation. Precision irrigation is another conservation practice that seeks to increase the efficiency of irrigation systems, by reducing pumping time and energy use.
Starting in 1998, Dr. Jeff Mitchell of UC Agriculture and Natural Resources (UC ANR) and a group of farmers, researchers, and agriculture professionals have been collaborating in California’s San Joaquin Valley to optimize the techniques and benefits of CT. Together, they formed the Conservation Agriculture Systems Innovation (CASI) Center with the goal of increasing the adoption of conservation farming systems to over 50 percent of California’s cropping acreage by 2028. CASI conducts research, demonstrations, and outreach to growers, agencies, and environmental and consumer groups.
CASI’s mission is twofold: improve the livelihoods of California farmers while conserving and improving natural resources. Working directly with growers and public agency representatives allows CASI researchers to develop projects that reflect an understanding of whole-farm systems and the importance of combining conservation practices to optimize climate benefits.
Farmers are no strangers to struggle or drought. But this four-year drought is different than others, they say. It’s more widespread, touching nearly everyone who turns on the tap or starts an irrigation pump.
This past summer, wells dried up and farmland sat idle. The drought also came to mean that life on the farm has likely changed forever.
“In the early years when we went through a drought, we tended to say that this too shall pass,” said Richard Waycott, president of the Almond Board of California in Modesto. “But there is a different consciousness now. People are looking at the future very differently.”
Farmers talk of a new reality – one in which droughts are more of the rule than the exception, and water availability, both above and below ground, becomes less certain.
It’s been a quarter century since government regulations limiting emissions of sulfur and nitrogen oxides from coal-fired power plants began to neutralize the problem of acid rain, but lakes in the northeastern U.S. and eastern Canada have been sluggish to recover.
Scientists have linked the delayed comeback to a lack of acid-buffering calcium in surrounding soils, which continued to acidify despite cuts in pollutants. Now, however, a study shows for the first time that soil acidification has begun to reverse across a broad swath from western Ontario to Maine (Environ. Sci. Technol. 2015, DOI:10.1021/acs.est.5b02904). Researchers hope improvements to forest health and lake water quality will follow.

The 2015 legislative year in California started off with a bang, climate policy-wise.
Speaking before the assembled members of the Legislature at his January inaugural address, Governor Jerry Brown outlined several bold objectives for the year 2030, including goals to produce 50 percent of our electricity from renewable sources, reduce petroleum use by 50 percent, and double the energy efficiency of existing buildings.
Perhaps most radical was the Governor’s declaration that “we must manage farm and rangelands, forests and wetlands so they can store carbon.” By this he meant agricultural practices—including many in the organic toolkit—that can draw down and hold atmospheric carbon in soils, perennial crops and conservation plantings.
Furthermore, in his budget proposal, Governor Brown included a new program called the Healthy Soils Initiative that “ensures that our agricultural soils have adequate soil organic matter (SOM). Increasing the amount of SOM from its current levels in soils can provide multiple benefits.” Existing and transitioning organic producers should be among those to benefit from this initiative since soil organic matter is a cornerstone of good organic practices.
Rose Marie Burroughs, along with her husband Ward and three of their children, organically farm in Merced County. Their products are branded under Burroughs Family Farms, and include the ABC’s of organics: almonds, beef, chickens, dairy, eggs…and olive oil, as well as artisan gouda cheese. Rosie and Ward serve as members of CalCAN’s Farmer Advisory Council.
Rosie attended a recent hearing on Central Valley climate adaptation held at UC Merced. We produced this summary of the proceedings.
How will drought, higher temperatures and extreme weather associated with climate change have an impact on our region in the coming decades? And how can we adapt to these challenges?
State Senator Bob Wieckowski (Fremont) and the Senate Environmental Quality Committee brought these questions to a legislative hearing at UC Merced on September 22nd. Farm Bureau member Rosie Burroughs attended and provided public testimony to the Committee, suggesting some ways to help growers adapt to climate change impacts.
We heard from panelists and scientists representing several state agencies and regional authorities. Significant shifts to the water cycle due to changing climate trends could have a sizable impact unless we rethink how we store and manage water, they said. More extreme heat days could have health impacts on outdoor workers and low-income communities. Central Valley agriculture may bear the brunt of the changes unless we have the tools we need to adapt.
In California’s Central Valley, farmers have been coping with diminishing water supplies, rising water costs, and other impacts of the ongoing drought. At CalCAN’s Climate and Agriculture Summit in March, Tom Willey of T&D Willey Farms discussed the impacts of drought and how he has responded to water shortages on his farm in Madera County.
Since 1981, Tom has grown an array of organic vegetables on his 75-acre farm with his wife Denesse. Specialty markets, restaurants, and Community Supported Agriculture (CSA) members enjoy Tom’s produce. Until recently, Tom served as Slow Food USA’s governor for the Central Valley, and he also advocates for sustainable agriculture through his writing, speaking, event organizing, and his monthly radio program, “Down on the Farm.”
SL: You spoke at our Summit in March about challenges regarding the drought and water issues. Now that we’re in the heat of summer, what’s the status on your farm and the region generally?
TW: We lost a shallow well on the farm in the past month or so, and we had to come up with an alternative supply. Shallow wells are going dry all over the county. It’s impossible to drill a new one or deepen an older one unless you’re already on a waiting list for a driller—most are booked for up to a year or two. On our farm, we plumbed into our deeper (500 ft) irrigation well. This well is designed to pump 1,000 gallons per minute, but at the moment, performance is closer to 650 gallons per minute. What I can say is that another dry winter would definitely spell disaster.
Carbon Sequestration in Grazing Land Ecosystems1
Maria Silveira, Ed Hanlon, Mariana Azenha, and Hiran M. da Silva2
This publication provides basic information about the important role of native and improved pastures (referred to as grazing land) in sequestering carbon from the atmosphere. Because of the relatively high sequestration rates and extensive area, grazing land represents an important component of terrestrial carbon dioxide (CO2) offset and is a significant sink for long-term carbon sequestration and greenhouse gas mitigation. This publication contains information for stakeholders, students, scientists, and environmental agencies interested in enhancing ecosystems services provided by grazing lands.
Global Carbon Cycle
The global carbon cycle consists of complex processes that control the movement of carbon between the atmosphere, land, and oceans. Although natural processes dominate the carbon cycle, human-induced activities can also alter these carbon transfers. In the atmosphere, carbon is mainly present as carbon dioxide (CO2). Large amounts of carbon are also present in the soil, primarily as soil organic matter. Soil organic matter plays a key role in determining soil quality and its potential to produce food, fiber, and fuel. During the past two decades, the global carbon cycle has received significant attention because of its role in global climate change.
Two important global topics are the rising atmospheric CO2 concentrations caused by human-induced activities (primarily combustion of fossil fuels) and the potential effects on climate change. In addition to CO2, increased atmospheric concentrations of nitrous oxides (N2O and NO) and methane (CH4) are also believed to cause global warming. Carbon dioxide, nitrous oxides, and methane (also known as greenhouse gases) can trap heat in the atmosphere and contribute to global warming. Levels of several important greenhouse gases have increased by 25% since large-scale industrialization began approximately 150 years ago, and this increase is primarily caused by energy use.
Plants remove carbon from the atmosphere during photosynthesis, a process done without human intervention. However, to address the contributions made by humans, the carbon must be stored or sequestered. Typically, carbon in plants undergoes several conversions. Some conversions are rapid, such as the addition of fresh plant material to the soil, while others may take long periods of time. For example, a large amount of carbon is already sequestered in our soil.
Field crop acreages are declining across the state, as water shortages and uncertainties continue to challenge California growers. Water scarcity has forced farmers to fallow land and sacrifice thirsty annual crops for more drought-tolerant perennials.
According to a recent USDA National Agriculture Statistics Survey (NASS) report, acreages are shrinking for several major field crops. Corn, sunflower, rice and cotton are among the victims of this historic drought. California growers planted 430,000 acres of corn this year, 17 percent less than the 520,000 acres planted in 2014. Sunflower acreage has dropped by 20 percent, with 35,000 acres planted this year, compared to 44,000 acres in 2014.
The latest episode of the Thrive podcast takes a close look at the ground beneath our feet. Soil, on which terrestrial life depends, is often ignored precisely because it is everywhere and yet invisible. Healthy soils contribute so much to human well-being, from nutritious food to clean water, and yet the soils of more than a fifth of all cropland, pasture, forest and woodland are degraded to some extent. Degraded soils, apart from being unable to meet the needs of the people who depend on them, also emit large amounts of greenhouse gasses, contributing to climate change.
How, then, can we best restore degraded soils? Sessions at Global Soil Week 2015 in Berlin, co-organized by the Water, Land and Ecosystems research program of CGIAR, provided a platform for people to share different approaches, each of which has something to offer.
Last month, the USDA announced its plan to invest an additional $21 million of Environmental Quality Incentives Program (EQIP) funds to support on-farm water conservation efforts in severely drought-stricken areas. The investment will expand financial and technical assistance to crop and livestock producers in eight states, including California, in an effort to promote practices that conserve water and build soil health.
Administered by the USDA’s Natural Resource Conservation Service (NRCS), EQIP supports on-farm conservation improvements through financial cost-sharing and technical assistance to growers. Over $27 million of FY 2015 EQIP funding is already targeted toward drought management practices in California. The additional funding will direct EQIP allocations to areas experiencing exceptional or extreme drought conditions, and focus on conservation practices that help farmers cope with drought, such as improving irrigation efficiency, implementing prescribed grazing, and building soil health through cover crops and reduced tillage. NRCS aims to both improve on-farm water use efficiency and also contribute to the long term resilience of crop, pasture, and rangelands against drought.
Humankind is faced with the continuing challenge of sustainably growing sufficient food to feed an ever-growing population. The United Nations Food and Agricultural Organization  citing a United Nations World Population Prospects report predicts that the earth’s population will reach 9.1 billion by the middle of this century.
Much of this growth will be in nations whose populations now suffer from malnutrition or outright starvation. In addition to a growing population, the increase in people will demand more food, more meat, and higher quality food because it will be more urban and wealthier according to FAO. Their estimate is that increased demand will require current food production to rise by 60 percent.
The challenge becomes more acute when it is understood that the land area for growing food is not expanding. Indeed, urban growth onto farmland and loss of arable (farmable) soil by wind and water erosion are reducing the available land area most suitable for farming. More land can be brought into production, but with a potentially high environmental and monetary cost.

Dirt: The Ecstatic Skin of the Earth by William Bryant Logan.
W.W. Norton & Company, New York, 1995.
William Bryant Logan’s book Dirt: The Ecstatic Skin of the Earth is a 202-page love song to the soil. Logan’s book is made up of multiple styles: part scientific fact, part narrative storytelling, part poetry, part history-lesson.
Logan’s writing is beautiful, meditative, metaphor-full, and poetic, filled with lyrical connections between surprising thoughts. He uses soil as the connective thread to examine multiple, immense ideas, many verging on discussions of the meaning of life.
To give an example of his style of writing, in taking on the beginning of life on earth (no small subject), Logan writes, “life is the story of bodies that learned to contain the sea…when you look for a creature to match the range of motion of the human hand, you find yourself back with the wiggling orange filaments of fungi and the gesture of acclamation of a spreading bacterial branch” (11,13).
Moving from the beginning of life, he takes on death in graphic detail in the chapter The Soil of Graves writing, “so in the end the tomb is empty, and human forms have been changed into apple forms. The soil of graves is the transformer. It is natural magic. The grave is a memory from which the story of the Earth is told” (57).
