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.
WASHINGTON - A top Interior Department official Tuesday will sign a San Joaquin Valley irrigation settlement with the Westlands Water District, signaling the end of a long-running legal battle, but marking the start of a hot new political fight.
After years of wrangling, negotiators agreed to a deal that absolves the federal government of the responsibility to provide irrigation drainage to farms in thte Westlands district. The government’s failure to provide the drainage as part of building the Central Valley Project led to tainted soil and serious environmental problems.
In return, according to lawmakers briefed on the deal Friday, the 600,000-acre Westlands district will retire at least 100,000 acres of farmland. The nation’s largest water district will also receive a potentially an advantageous new type of contract and have its own remaining debt to the government forgiven, among other changes.

This year marks the 40th anniversary of the groundbreaking Agricultural Labor Relations Act (ALRA). At the time that it was enacted, it was a progressive way to provide, for the first time, legal protections for farmworkers who engage in direct action to improve their wages. It is arguably the best pro-labor law in the nation.
Despite this, California’s farmworkers remain the state’s poorest-paid production workers. Current annual average wage rates paid to California’s direct-hire farm laborers are lower, when adjusted for four decades of inflation, than they were in 1974, before the law was passed. Seasonally employed crop worker wage rates are even lower. And fewer farmworkers today are covered by labor-management agreements than in 1974.
Our main thesis in this article is that the economic status of California’s farm laborers has deteriorated, despite the Agricultural Labor Relations Act and the remarkably positive performance of the industry as a whole.
The prospect that ALRA’s paradigm of labor versus capital would ultimately benefit most workers has largely been a failure. Labor unions and employers now battle in the courts and state legislature to gain advantage against one another, while many workers’ meager economic gains come from increases in the state’s minimum wage.
Why have wages decreased?
Implementation of the ALRA led to prolonged struggles in the legislature, the courts, and in the agency itself. During its initial 6-month period, hundreds of union representation elections were conducted and numerous labor-management agreements signed.
Annual average wage rates for farmworkers rose dramatically.
But the industry fought back. A newly elected Republican governor (Ronald Reagan) appointed a pro-employer ALRB General Counsel in 1983, and the agency’s budget was slashed. By 1986, pro-labor members of the ALRB were a minority. Labor-management agreements expired, pro-union farmworkers were fired or blacklisted without recourse, and the General Counsel publicly campaigned against union activities.
Wage rates (measured in constant 2014 dollars), including earnings and paid employment benefits, have actually declined for direct-hire field & livestock workers since that initial rapid increase.
In 1974, farmers and ranchers reported to the USDA Farm Labor Survey (USDA FLSUSDA) the annual average wage rate for California’s direct-hire field & livestock labor (production workers) was $2.60 per hour ($13.50 per hour in inflation-adjusted 2014 dollars). But in 2014, California’s farmers and ranchers reported the annual average wage rate for direct-hire field and livestock workers was $11.33 per hour, or $2.19 per hour below what was needed to keep up with inflation.
Employers say they cannot afford to pay higher wages. But impressive economic performance of California agriculture is exemplified by the increase of farm cash receipts from the sale of agricultural commodities during this same period. In 1974, sales were about $7 billion (or the equivalent of $34 billion in 2012 dollars), while the corresponding figure in 2012 was $43 billion [Martin. 2015].
Thus, California farm operators realized real sales growth of 26%.
At the same time and just as remarkable, California farm production became ever more concentrated. By 2012, California’s largest farms had a 63% share of all farm sales in the state. In all of the other states combined, farms of that size had less than a 28% share of all farm sales. California’s 64,200+ small farms accounting for 82% of all farms in the state had a combined total of just 5% of farm sales.
Size concentration is important in today’s context because many of the largest produce farms are vertically integrated – described as grower-packer-shippers – and more likely to negotiate year-round supply contracts directly with supermarket chains, fast-food venders, fresh-cut processors, and other large-volume purchasers. While benefitting from economies of scale, these arrangements may result in large grower-packer-shipper operations becoming more vulnerable to the concerns of retail customers, especially regarding food safety. During the late 1970/s protracted labor dispute and boycott of Red Coach brand lettuce, the UFW relied on this vulnerability to focus boycott activities.
The United Farm Workers of America, led by Cesar Chavez, responded to the anti-union administration of the ALRA in the 1980s by pouring substantial resources and effort into a struggle to beat back pro-employer actions. In fact, the UFW stopped organizing in the fields to focus on defending the ALRA. It’s clear from the data on income presented above that the law has not worked.
It is well-known that farmers and ranchers do not command the major share of consumer food expenditures. In other parts of the nation alternative forms of concerted action by farm workers have led to improvements in their earnings. Most significantly, these successful efforts have involved mobilizing consumers to leverage food processors, supermarkets and fast food outlets to assume a significant share of the responsibility for improving farmworker wages. Since most of consumers’ food dollars go to processors and vendors, not to farmers, it is increasingly apparent they must share responsibility for the wages of those who produce food products.
Farm worker organizations pioneered the mobilization of consumers to pressure food system vendors, whether processors, supermarkets or fast food chains, to underwrite increases in farm labor earnings. This approach has relied on boycotts outside the framework of traditional labor-management relations.
The first notable instances of this alternative form of concerted action were developed in the 1970s by the Farm Labor Organizing Committee (FLOC), initially among processing tomato workers in the Midwest. The national boycott of Campbell Soup Co. sought to bring the company to the table to underwrite a significant share of improved farm worker wages. Some years later, FLOC used the same tactic to force Vlasic Pickle Company to underwrite improved earnings for cucumber workers in North Carolina.
In Florida, since the mid-1990s the Coalition of Immokalee Workers (CIW) has mobilized nationwide consumer pressure on large corporations like Wal-Mart to directly supplement tomato harvester earnings by an additional penny per pound. Wages increased up to 17%, depending on picker productivity. And all Florida tomato workers benefited, not just CIW members.
This past summer, Stop & Shop supermarkets, along with the other stores owned by Ahold, agreed to participate in the CIW program. Stop & Shop is the first of the major “pure” supermarket chains to sign up with CIW.
The CIW agreement with Wal-Mart contemplates expanding coverage in the future to other produce items, not just tomatoes. While the primary focus of this form of concerted action is to raise farm worker earnings, other changes in workplace conditions have also been developed under CIW agreements, including formal grievance procedures, workplace safety education, and training about sexual harassment in the workplace----all on paid company time.
More recently, consumer petitions to U.S. food vendors, stimulated by a dramatic Los Angeles Times exposé, directly led to increased wages for 30,000 Mexican farmworkers in Baja California’s produce export industry. Their main leader was Fidel Sanchez, a veteran of CIW organizing, and they mounted the same tactic as CIW, i.e., seeking to directly persuade major supermarkets to underwrite their demands. At least one grower-packer-shipper with operations in the affected region commented privately that a vendor contacted the firm directly wanting answers to the workers’ complaints.
Based on our review of current conditions, it is clear that a new paradigm is needed for labor relations in California agriculture. Food marketers, processors, farmers and ranchers, farm workers and farm labor organizations should be brought to the table to inform policy makers on developing mechanisms whereby all parties assume joint responsibility for improving the economic status of farm labor.
Representatives of farm labor, farmers, food processors, and food vendors need to be brought together in a new paradigm in order to organize and empower farm workers. Farmers and farm worker organizations need to recognize this opportunity and their common interests. Farmers and ranchers need workers. Workers and farmers have a common interest in coping with the current drought, in the immigrant rights crisis driving the farm labor shortage, and in the quality of rural housing and healthcare.
Unlike direct worker-grower discourse about wages and working conditions, the effective mobilization of consumers has become effective because some vendors realize they are the principal point of contact for consumers’ relationship to the modern food system. If consumers can be persuaded that improvements in farm labor wages and working conditions are a necessary component of food purchase choices, then underwriting those improvements may become a wise business choice.
Progress to improve the economic status of farm labor families requires cooperation among all the major players in the food system: farmers and ranchers, food processing companies, supermarkets, fast food vendors, and farm labor organizations.
It appears that farm labor organizations are currently the weakest link among the major players in the food chain. With fewer than 10,000 California farmworkers represented by collective bargaining agreements, and employers choosing to fight for every possible advantage in the courts and the state legislature, there is an obvious imbalance between labor and the corporations that now dominate the food system. Only when farmworkers are organized and empowered will cooperation of all participants in the food system become meaningful. There is an urgent need to examine alternatives to the ALRB. We propose that change will come only through cooperation of stakeholders across the food chain. And pressure needs to be exerted by consumers who care about the workers who grow and harvest their food.
Consumers can be instrumental in improving the lives of farmworkers.
You can start by telling your grocer to contribute a fair share of wages paid to those who put food on your table.
