The unintended consequences of clean fuel policies

How policies affect emissions, land use, and the prices of fuel and vegetable oils

Over the last two decades, both the federal government and state governments have enacted policies to reduce greenhouse gas (GHG) emissions in the transportation sector. In a new Special Issue of ARE Update, University of California agricultural economists explore how these federal and state renewable fuel policies have affected biofuel production for motor and aviation fuels and consider how these policies have affected land use and food prices. Their research shows that as U.S. demand for renewable diesel began to outpace supply, consumer prices for vegetable oil—which is used as a feedstock for renewable diesel—surged.

The national Renewable Fuel Standard (RFS) and California's Low Carbon Fuel Standard (LCFS), implemented in 2006 and 2011, respectively, have led to an increase in the amount of biofuels consumed and produced in the United States. While the RFS mandates that a minimum volume of renewable fuels be blended into U.S. transportation fuels, the LCFS sets an annually increasing targeted reduction in transportation-related carbon emissions. The LCFS set a 2030 target date to reduce GHG emissions by 20% through the development of a carbon trading program that requires refiners who produce ‘dirtier' fuels to buy credits from those who produce cleaner (e.g., renewable) fuels.

The authors show that after 2020, whenLCFS credit prices (i.e.,biofuel subsidies) were high, California saw an increasing volume of motor fuel coming from renewable diesel — which previously only made up around 5% of the state's diesel blend. Currently, the retail diesel blend in California is 35% conventional diesel and 65% renewable diesel.

By 2023, renewable diesel was the most consumed renewable fuel in California and also generated the most credits under the LCFS. Because renewable diesel is a perfect substitute for “conventional diesel,” it does not need to be blended with conventional diesel, unlike biodiesel which is chemically different from renewable diesel.

The agricultural inputs used to make renewable diesel can be used not only in the production of motor oil, but also in the development of sustainable aviation fuel (SAF). Additional tax credits set forth in the 2021 Inflation Reduction Act aim to bring about a 100-fold increase in the production of these fuels by by the end of decade. However, the authors of the second article show that current incentives to produce SAFs are not large enough to overcome the opportunity cost of instead using these fuels for on-road use.

After the drastic increase in demand for renewable diesel (up 500% over the last five years), a higher percentage now comes from edible vegetable oils. This increased demand almost certainly plays a role in increasing inflationary pressure on foods such as cooking oils.

“From 2018 to 2024, food-at-home inflation was 24%, but over the same period, fats and oils inflation was 83%,” said UC Davis professor and co-author Jens Hilscher.

The increased demand for these oils from the United States has also led to booms in production in countries such as Brazil and Indonesia, and some of the land conversion into these vegetable oil crops could result in deforestation. Greenhouse gas emissions are a global challenge. The authors show that local biofuel mandates often succeed in moving U.S. consumption of these fuels from one product or region to another without necessarily decreasing emissions at the national level. Their research emphasizes the importance of a coordinated effort to target emission reductions with a careful eye to the indirect consequences that inevitably result from ambitious policies.

UC food-safety specialist tests biosensors to ensure safe produce

 

Ahmed El-Moghazy joined UC Agriculture and Natural Resources as a UC Cooperative Extension food safety specialist in February and is based at UC Riverside. Food safety, according to El-Moghazy, are measures that ensure food is free from harmful contaminants, prevent foodborne illnesses and is safe to eat. El-Moghazy is responsible for assisting California farmers and food processing facilities to enhance food safety practices by training appropriate personnel and addressing food-safety issues on their farms.

As the principal investigator for the 2-SAFE Lab at UC Riverside, El-Moghazy is investigating the accuracy and applicability of point-of-use biosensor technology. The small, lightweight and easy-to-use sensor can be used while out in the field or in a packing house to test contamination of liquids such as irrigation and washing water or solids like food samples.

Testing for foodborne pathogens traditionally takes two to three days and the process can be costly. The biosensor technology that El-Moghazy is using is inexpensive and can provide results within one work shift, which allows businesses that grow fresh produce to confirm the safety of their products before sending them to the market.

The alternative, selling contaminated food to consumers, is not only detrimental to human health, but can ruin the reputation of businesses, making way for unanticipated costs associated with recalling contaminated products and regulatory consequences including fines and sanctions. 

El-Moghazy is also developing the next generation of antimicrobial surface coatings and materials that can rapidly control the foodborne pathogens and hinder the transfer of harmful bacteria from contaminated food to non-contaminated food.

El-Moghazy is optimistic that his research can safeguard public health, reduce the burden of foodborne illness and protect the integrity of businesses. Although El-Moghazy serves the entire state, he is dedicating a large part of his needs assessment and efforts in Southern California where high-value specialty crops such as avocados and citrus are grown.

"Did you know that one in every six Americans get sick from eating food contaminated with a foodborne pathogen?" asked El-Moghazy. Understanding the fatality of foodborne illnesses, El-Moghazy believes that increasing awareness through education is an essential aspect of his role. "It's true, but not many people realize this, or that 40% of foodborne illnesses stem from fresh produce."

To protect consumers, the U.S. Food and Drug Administration requires farms with a certain level of annual sales (adjusted for inflation) of fruits and vegetables typically consumed raw to have one employee who has completed an FDA-approved Produce Safety Rule Grower Training.

In addition to certified trainings, El-Moghazy offers technical assistance to ensure growers comply before and after inspections, as well as resources for several topics including produce safety, agriculture water, flooding, soil amendments, worker health, hygiene and training and postharvest handling and sanitation. He can also assist in developing food-safety plans and other general farm food-safety protocols. His technical expertise covers all aspects of food production and supply including irrigation water quality, hygiene of harvesting tools and transportation.

Before joining ANR, El-Moghazy completed two years as a visiting scholar in the UC Davis Biological and Agricultural Engineering department before continuing as a postdoctoral fellow in the UC Davis Food Science and Technology department for 5 years. Much of his work was rooted in the development of biosensors and antimicrobial materials for food safety. While in Davis, he collaborated with local farms and food processing companies on food safety research and extension.

El-Moghazy earned a Ph.D. studying developmental biosensors for food safety applications to detect pesticides residues from a joint program offered by University of Perpignan in France and Alexandria University in Egypt. He also earned a master's degree in developmental biobased fungicides and a bachelor's in agriculture science from Alexandria University. Finally, he completed a fellowship at the Institute of Plant Protection, Szent Istvan University in Hungary, where he studied how to extend shelf-life of fresh produce using biomaterials.

El-Moghazy is based at UC Riverside in the Department of Microbiology and Plant Pathology. He can be reached at aelmogha@ucr.edu or  (951) 827-0257.

A U.S.-China trade war would cost California farmers

Loss of China's preferred trade status could hurt crop, dairy and livestock exports

The Biden administration recently announced large, increased tariff rates for Chinese electric vehicles, solar cells, semiconductors, and aluminum and steel products. This raises the possibility of another trade war with China that could impact agriculture. 

Economists from UC Davis and North Dakota State University evaluated the potential implications of the U.S. revoking China's Permanent Normal Trade Relations (PNTR) status. They found that if China retaliated against a change in China's PNTR status, it could lead to a 9.5% increase in China's agricultural import tariffs, resulting in potential trade losses to California agriculture of around $1 billion annually.

California agriculture was hit hard by the 2018-19 trade war with China, and many industries have still not recovered from its effects. Despite this, there is increasing support in Congress for further restrictions on trade with China, with proponents asserting that China is not complying with the World Trade Organization's regulations.

The authors' research suggests that some product groups – such as horticultural products, dairy, livestock and meats – would likely experience even steeper than average increases in import tariffs.

“The impact on import tariffs for non-agricultural sectors would be even larger, with the average import tariff going up from 3.9% to 32.5%,” said co-author of the study Colin A. Carter, Distinguished Professor in the Department of Agricultural and Resource Economics at UC Davis. 

For all California agricultural exports, they estimated an average decline in export value between 28.4% and 34.8% when comparing a scenario where China's PNTR status is revoked to one where it is not. This translates into an estimated trade loss of between $800 million and $1 billion, using 2023 California agricultural exports. Some crops that rely heavily on China for exports, such as tree nuts, would be more severely impacted by these effects, particularly considering that some of them are still subjected to residual tariffs from the 2018-19 trade war.

The last trade war between the United States and China led to significant decreases in crop prices and lost export opportunities. As co-author Sandro Steinbach, Associate Professor in the Department of Agribusiness and Applied Economics and the Director of the Center for Agricultural Policy and Trade Studies at North Dakota State University notes, “Once access to a market is lost, gaining it back is difficult, as the 2018-19 trade war has shown.”

Gill joins UCCE as environmental horticulture advisor

Haramrit Gill joined UC Cooperative Extension on April 1 as an environmental horticulture advisor for Tulare, Kings, Fresno and Madera counties.

She will be identifying landscape plants that are heat-tolerant, disease-resistant and fire-resistant. Gill will be researching California native plants with sustainable attributes that include superior adaptation, biodiversity enhancement, water efficiency and soil health benefits.

A native of Punjab, India, Gill earned her undergraduate degree in agriculture followed by a master's degree in horticulture at Punjab Agricultural University, where her research focused on micropropagation and haploid production in muskmelons. She earned a Ph.D. from the Department of Horticultural Sciences at Texas A&M University.

Her early research investigated the impact of nitrogen on spinach root architecture. Her doctoral work concentrated on rose breeding and deciphering the genetic underpinnings of flower color transition traits, fragrance and dwarfing in roses, with a particular focus on the intriguing phenomenon of flower color transformation from yellow to dark pink as blooms matured. She also collaborated on projects aimed at enhancing heat tolerance and disease resistance in roses. 

Gill is based at the UCCE office in Tulare and can be reached at hamgill@ucanr.edu.

Jordan joins UCCE as forestry and natural resources advisor 

Christian Jordan joined UCCE on March 18 as a forestry and natural resources advisor for Shasta, Siskiyou and Trinity counties. He will work to advance forest resilience and sustainable management on private and public lands, with a focus on conifer forest resource management and sustainable natural resources. 

In 2020, Jordan completed a Master of Forestry at UC Berkeley, with an emphasis on forest resilience in the context of increasingly severe wildfires. Prior to joining UC ANR, he worked in the private sector in defensible space and home hardening, installing residential exterior sprinkler systems for ember defense.  

Jordan brings a diverse educational and work background to the position. In 2014, he earned a bachelor's degree in geography from UC Berkeley, writing a thesis on future climate and viticulture in Napa and Sonoma counties. Upon graduating, he worked in the wine industry before returning to natural resources. 

Jordan is based at the UCCE office in Redding and can be reached at cjordan@ucanr.edu.

Pastrana joins UCCE as plant pathology advisor 

Ana Pastrana joined UCCE on Jan. 16 as a plant pathology advisor serving Imperial, Riverside and San Diego counties.

In her role, Pastrana will collaborate with pest control advisers and support growers with disease management. In addition to identifying high priority concerns, she will conduct research and develop educational content that addresses growers needs.

Before moving to Southern California, Pastrana worked as a research scientist on plant pathology at the University of Seville, Spain, and at Vineland Research and Innovation Center in Canada. Previously, she completed a postdoctoral assignment in the Department of Plant Pathology at UC Davis in the Thomas Gordon Lab, where she specialized in soilborne diseases affecting strawberries and blackberries. 

While attending the University of Seville, Pastrana earned master's and bachelor's degrees in biology. At Investigación y Formación Agraria, Pesquera, Alimentaria y de la Producción Ecológica, a government institution in Spain, she earned a Ph.D. and completed her dissertation on strawberry diseases. 

“At that time, Europe banned methyl bromide and other soil disinfectants. Strawberries rely on these disinfectants so plenty of soilborne diseases emerged,” Pastrana said. 

Originally from Seville, Spain, Pastrana said that her small hometown is surrounded by plum and citrus trees. Her mother, like many others, worked in the agricultural industry and Pastrana wondered how plant life works, inspiring her to study biology. 

As a Ph.D. student, Pastrana didn't know she would pursue plant pathology specifically because she was open to studying diseases in general whether it be humans, animals or plants.

“Plant pathologists are like doctors. Not everyone is happy to work with us because it usually means that there is some sickness involved,” said Pastrana. “But if growers work with pathologists from the beginning, we can focus on preventative care and helping to protect plants from getting sick.” 

Pastrana is based at the UCCE office in Holtville and can be reached at ampastranaleon@ucanr.edu.

Mokwunye named area IPM entomology advisor 

Idongesit Mokwunye joined UCCE on Jan. 3 as an area integrated pest management entomology advisor.

She will be studying insect pests of economic importance affecting tree fruit and nut crops, such as pistachio, almond, walnut, table grapes and stone fruit. Major pests include navel orangeworm, mealybug, carpophilus beetle, mites and scale insects.

Prior to joining UC ANR, Mokwunye worked as a nut crop entomologist at the Cocoa Research Institute of Nigeria for over 15 years and headed its Crop Protection Division.

“My journey into entomology as a career started when I was posted to the Cocoa Research Institute of Nigeria for the mandatory one-year National Youth Service Corp,” Mokwunye said.
