Conservation advocates have long touted the need to preserve Sonoma County’s bucolic landscape, but a report released last week for first time assigned a dollar value to those open spaces and their natural resources.
The value of services provided by undeveloped and working lands, both public and private, in Sonoma County ranges from $2.2 to $6.6 billion annually, according to the report from the Healthy Lands and Healthy Economies Initiative. The study stems from a years-long collaboration between open space and conservation districts in Sonoma, Santa Clara and Santa Cruz counties.
“It’s clear that our community values open space and working lands, but the main point of the report is that not only do we value them, but these lands have an immense value that’s not commonly understood in the typical market framework,” said Karen Gaffney, conservation planning manager for the Sonoma County Agricultural Preservation and Open Space District.
The report assigns value to a variety of ecosystems. It accounts for green spaces that absorb runoff to curb flooding while filtering out pollutants. It highlights the benefit of soil, which captures and stores atmospheric carbon and sustains ground cover to prevent damaging erosion. It quantifies the public health benefit provided by trees and plants, which boost air quality, and of open spaces that harbor insect- and wildlife that can limit pests.
It’s the first clear picture of the total estimated value of Sonoma County’s “natural capital,” or its stock of natural assets, and the way they can provide cost-effective alternatives to man-made infrastructure.

Douglas Kent is the author of Firescaping: Creating fire-resistant landscapes, gardens and properties in California’s diverse environments
You are battered and fatigued, but the fight to save your property and community is far from over.
In the wake of recent wildfires on the North Coast, the risk of topsoil loss and the flow of debris has grown.
Erosion leaps as high as 200 percent following fires in urbanized areas. With this increase comes mass sedimentation, alteration of streambeds, property and infrastructure damage, and, in some cases, even injury and death.
We need to hold our ground.
Fires eliminate canopies, burn off leaf litter and expose the soil. When there is nothing to slow or stop them, wind and water gain leverage. Soil gets shoved around as a consequence.
But the problem is not just the lack of protective cover. Recently burnt landscapes also have to contend with repellency. Fires cook the waxes that are natural to our soils. When these waxes cool, they coat the first inch of soil with a repellency layer, stopping water from infiltrating.
The consequences can be dire when the lack of protective cover and repellency are combined. Fire-scarred communities can produce incredible amounts of runoff and debris flow.This runoff and debris can overwhelm storm water drainage systems, leading to extensive erosion elsewhere. Worse still, debris flowing down slopes can overrun homes, businesses and small communities. These types of events can, and have, lead to personal injury and death.

By any measure, the fires that tore through Northern California were a major disaster. Forty-two people are dead, and 100,000 are displaced. More than 8,400 homes and other buildings were destroyed, more than 160,000 acres burned—and the fires aren’t all out yet.
That devastation leaves behind another potential disaster: ash. No one knows how much. It’ll be full of heavy metals and toxins—no one knows exactly how much, and it depends on what burned and at what temperature. The ash will infiltrate soils, but no one’s really sure how or whether that’ll be a problem. And eventually some of it—maybe a lot—will flow into the regional aquatic ecosystem and ultimately the San Francisco Bay.
That’s the bomb. Here’s the timer: An old, grim joke about the California says that the state only has three seasons: summer, fire, and mudslides. Those mudslides happen because of rain; the Santa Ana (or Diablo, if you’d prefer) wind-driven wildfires of autumn give way to a monsoon season that lasts through winter and into spring. The rains of 2016-2017 ended a longstanding drought and broke all kinds of records.
Scientists and environmental health agencies know, mostly, what to expect from ash that comes from burned vegetation. But these fires included something a little new. They burned through the wildland-urban interface and into cities. “For how many structures that were burned in fairly small areas in these fires, I think that’s a first-of-its-kind event,” says Geoffrey Plumlee, associate director of environmental health for the US Geological Survey. “The concern is, can they get it cleaned up before the heavy rains come?”

Overview from the CALCAN (California Climate and Agriculture Network) website:
Climate Smart Agriculture Programs – The state of California currently has four Climate Smart Agriculture programs that provide resources for California farmers and ranchers to reduce greenhouse gas emissions and store carbon in soils and trees, while providing multiple benefits to agriculture and the environment. The programs are funded with proceeds from the state’s cap-and-trade program.
Healthy Soils Initiative – The Healthy Soils Initiative was proposed by Governor Brown in 2015 and received initial funding of $7.5 million in 2016. The Initiative provides funding for farmer and rancher incentives to increase carbon storage in soils and reduce overall greenhouse gas emissions through practices that build healthy soil such as compost application, cover crop, reduced tillage, conservation plantings and more. The program will also fund on-farm demonstration projects to provide growers, researchers and other ag professionals strategies for mitigating climate change in agriculture.
State Water Efficiency & Enhancement Program (SWEEP) – The program funds growers to improve their irrigation management practices to save water and energy and reduce related greenhouse gas emissions. Eligible project activities include pump upgrades and solar pump installation; conversion to drip or micro irrigation; improved water storage and/or recycling, soil moisture monitoring and irrigation scheduling.
Sustainable Agricultural Lands Conservation Program (SALCP) – The program funds local government projects and permanent easements on agricultural lands at risk of development to prevent sprawl.
Dairy Digester Research and Development Program (DDRDP) – The program funds dairy digesters and related research to reduce methane emissions from the dairy sector. A portion of the funding will be allocated in 2017 to a new program called the Alternative Manure Management Program (AMMP).
Gov. Jerry Brown recently signed Assembly Bill 398, which extends cap-and-trade, California’s cornerstone climate change program, through 2030. The program requires the largest emitters of greenhouse gas emissions (e.g., the oil and gas industry, cement plants, large food processors) to cut their emissions. Without putting a price on carbon, we are unlikely to meet our climate change goals, the most ambitious in the country.
The state Legislature and governor will now debate how to budget billions of dollars in cap-and-trade revenue. In the past three years, California has invested more than $3 billion of cap-and-trade funds in our communities to accelerate the transition toward a clean energy economy. In January, Governor Brown proposed an additional $2.2 billion for the 2017-18 fiscal year.
To date, the money has been invested across California on projects that reduce emissions by weatherizing homes, installing solar panels, improving public transportation, building transit-oriented housing and more. In addition to these urban strategies, the state has also embraced sustainable agricultural solutions to climate change.
Since 2014, nearly $200 million has been granted to farmers and ranchers to reduce greenhouse gas emissions and to store carbon on their land. The country’s first Climate Smart Agriculture programs are demonstrating to the world that farmers and ranchers can be leaders in climate innovation.

One Spring afternoon in 2014, on a small vegetable farm that Paul Kaiser runs in a particularly chilly valley in Sebastopol, California, a group of agriculture specialists gathered around a four-foot steel pole. The experts had come to test the depth and quality of Kaiser’s top-soil, and one of them, a veteran farmer from the Central Valley named Tom Willey, leaned on the pole to push it into the dirt as far as he could. On a typical farm, the pole comes to a stop against infertile hard-pan in less than a foot. But in Kaiser’s field, the pole’s entire length slid into the ground, and Willey almost fell over. “Wow, that’s incredible,” he said, wondering if he’d hit a gopher hole. The whole group burst out laughing. “Do it again! Do it again!” said Jeff Mitchell, a longtime professor of agriculture at the University of California at Davis.
The group successfully repeated the exercise, over and over—for fun, for photo ops, and to be sure that Kaiser really had accomplished the various feats he talks about, which he does almost incessantly these days. It’s not the easiest sell. Kaiser, an ebullient former woodworker who was only 40 when I first visited, farms a mere eight acres, and harvests fewer than three of them. Nonetheless, his methods are at the forefront of a farming movement that is so new (at least in the U.S.), and so built for a climate-changed world of diminishing rains, that it opens up gargantuan possibilities. One might call this methodology sustainability on steroids, because it can generate substantial profits. Last year, Kaiser’s Sonoma County farm grossed more than $100,000 an acre, which is 10 times the average per-acre income of comparable California farms. This includes Sonoma’s legendary vineyards, which have been overtaking farmland for decades, largely because wine grapes have become much more lucrative these days than food, at least the way most farmers grow it.
Kaiser and his wife, Elizabeth, manage all of this without plowing an inch of their ground, without doing any weeding, and without using any sprays—either chemical or organic. And while most farmers, even on model organic farms, constantly tinker with various fertilizer cocktails, Kaiser concentrates on just one: a pile of rotten food and plants, commonly known as compost, and lots of it. Kaiser then adds this compost to a rare blend of farming practices, both old and new, all aimed at returning dirt to the richest, most fertile seedbed possible. “It’s unique,” Mitchell told me after his visit. “I’ve never seen anything approaching that kind of thing.”

Toby Hemenway, a leading writer, teacher and crusader for permaculture, died Tuesday at his Sebastopol home because of complications from pancreatic cancer.
Hemenway, 64, wrote a top seller on permaculture, a term coined in the late 1970s mixing “permanent” and “agriculture” to describe a new approach to agriculture and community design bringing together elements that sustain and support each other.
“He was really a big deal,” said Kellen Watson, senior programs coordinator with Daily Acts, a Petaluma-based sustainability education program. “He wrote the top-selling permaculture book in the world,” for many people their first introduction to the subject.
That book, 2009’s “Gaia’s Garden — A Guide to Home-Scale Permaculture,” was considered the most easily understandable book on the topic, presenting basic permaculture concepts and principles with clarity and elegance, as well as detailed how-to tips for implementing them in a garden.
It was named by the Washington Post as one of the 10 best gardening books of 2010 and has sold more than 250,000 copies.
Hemenway could talk about soil from a cosmic perspective — how the elements of life were molded during the Big Bang, inside stars, and in explosive supernovae.
Then he would bring it down to earth.
“Soil is miraculous,” he wrote in “Gaia’s Garden.” “It is where the dead are brought back to life.”

Santa Rosa is buying a Petaluma pasture to make sure it has enough places to put people’s processed poop.
The city is close to acquiring a 235-acre Lakeville Highway hay ranch so it can use the property to spread a byproduct of the wastewater treatment process known as biosolids.
The approximately $2 million deal, which was advanced by the Board of Public Utilities Thursday, highlights the pressures the city faces in finding affordable ways to recycle waste in an era of increasingly stringent environmental regulations.
Santa Rosa recycles its wastewater to irrigate crops and produce geothermal energy at The Geysers, the latter solution costing the city $205 million to build while earning engineering and sustainability awards.
But less known by the general public is what happens to the 26,000 tons of thick black sludge that remains behind annually after the main treatment processes are complete.
That’s enough to “fill the entire playing field of AT&T Park eight feet deep every year,” said Mike Prinz, director of subregional operations for Santa Rosa Water.
More than a third of it is mixed with green waste like chopped up leaves and grass clippings to make high-quality compost, most of which is sold to local farms, vineyards and landscaping companies.
A far cheaper option has long been to apply the nutrient-rich material, which has the consistency of wet coffee grounds, directly to farmland as fertilizer.
Because the waste goes through an extra 21-day digestion process to capture methane to power the Llano Road treatment plant, it has far fewer pathogens and odors than the byproducts of other treatment plants.
Nevertheless, there are strict rules about how it can be applied, including that it be disked into the soil, set back from creeks and public access restricted after application.

In [Holistic Planned Grazing], livestock are managed as a tool for large-scale land restoration, mimicking the herding and grazing patterns of wild ruminants that coevolved with grassland ecosystems. Animals are moved so that no plants are overgrazed, and grazing stimulates biological activity in the soil.
May, 2014. The degradation of soils from unsustainable agriculture and other development has released billions of tons of carbon into the atmosphere. But new research shows how effective land restoration could play a major role in sequestering CO2 and slowing climate change.
In the 19th century, as land-hungry pioneers steered their wagon trains westward across the United States, they encountered a vast landscape of towering grasses that nurtured deep, fertile soils.
Today, just three percent of North America’s tallgrass prairie remains. Its disappearance has had a dramatic impact on the landscape and ecology of the U.S., but a key consequence of that transformation has largely been overlooked: a massive loss of soil carbon into the atmosphere. The importance of soil carbon — how it is leached from the earth and how that process can be reversed — is the subject of intensifying scientific investigation, with important implications for the effort to slow the rapid rise of carbon dioxide in the atmosphere.
According to Rattan Lal, director of Ohio State University’s Carbon Management and Sequestration Center, the world’s cultivated soils have lost between 50 and 70 percent of their original carbon stock, much of which has oxidized upon exposure to air to become CO2. Now, armed with rapidly expanding knowledge about carbon sequestration in soils, researchers are studying how land restoration programs in places like the former North American prairie, the North China Plain, and even the parched interior of Australia might help put carbon back into the soil.

The phrase is suddenly on the lips of every major player in the sustainable food movement.
Michael Pollan deemed it agriculture’s “secret weapon” in a December op-ed for the Washington Post. Bill McKibben, in his praise for an upcoming book on the topic, described carbon farming as “a powerful vision,” one that he hopes will “presage major changes in our species’ use of the land.” Paul Hawken went so far as to call it “the foundation of the future of civilization,” with potential to “surpass the productivity of industrial agriculture.
”Why all the hubbub? And, for that matter, what exactly is it about?
Carbon farming is agriculture’s answer to climate change. Simply put, the goal is to take excess carbon out of the atmosphere, where the element causes global warming, and store it in the soil, where carbon aids the growth of plants. The principle is pretty straightforward—the practice, not so much.
Most folks understand that burning fossil fuels puts carbon that was once buried deep beneath the earth into the atmosphere, turning the planet into one big greenhouse in the process. But in addition to petroleum underground, the soil on the surface of the earth contains a sizable store of carbon in the form of organic matter—the stuff that environmentally aware farmers and gardeners are always striving to maximize. Plants add organic matter to the soil when they decompose, and photosynthesis, by definition, removes carbon dioxide from the air and pumps it through the roots of plants and into the soil.
Concern over climate change may have thrust the concept of carbon farming into the limelight—25 countries pledged to pursue it during the December climate talks in Paris—but ranchers like Gabe Brown, who raises livestock and an array of crops on 5,000 acres outside Bismarck, North Dakota, have preached its virtues for decades. “All soil biology eats carbon, and that’s how nutrients cycle,” explains Brown of the network of microbes and fungi and earthworms underground. “Farmers need to think of carbon as their fertilizer, because it’s what drives a healthy system.”
