When the pandemic began, we built on an ongoing interdisciplinary research project with organic vegetable farmers on the California Central Coast to track how those growers adapted to the crisis. We conducted surveys in April 2020 and January 2021 to determine impacts on farmers and how farm size, market channels, and management strategies influenced a farm's ability to adapt to and recover from pandemic-induced disruptions. We found that mid-sized farmers with flexible and diverse marketing channels could navigate changes from the pandemic with minimal losses and, in some cases, economic gains. By contrast, smaller farmers with limited resources, especially those with disadvantaged backgrounds and limited access to technology, experienced more drastic impacts, including lost markets, labor shortages, and increased childcare needs. The lessons learned can inform a transition toward more sustainable, resilient agroecological systems.","PeriodicalId":9409,"journal":{"name":"California Agriculture","volume":"212 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139301794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2017–2018, a team of University of California Agriculture and Natural Resources (UC ANR) researchers and extension professionals developed a workshop series for urban farmers in California based on results of a prior needs assessment. After conducting 16 workshops in the state's largest urban centers, the team evaluated what participants learned and how they put their knowledge into action. The evaluation highlighted urban farmers' ongoing challenges and found that economic issues such as profitability and land access are some of the greatest barriers for urban farming in California. An unexpected positive outcome was the opportunity for participants to network and meet other farmers. Urban farmers expressed the need for more opportunities for mentoring and building partnerships with other farmers and organizations. Evaluation results suggest that California's urban farmers may be more diverse than California farmers as a whole, and that they are often beginning farmers.","PeriodicalId":9409,"journal":{"name":"California Agriculture","volume":"1 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42259471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We implemented youth participatory action research (YPAR) projects over three years at five schools. The YPAR approach integrates science learning and civic engagement by empowering youth, with the help of adult facilitators, to decide upon a community issue to research, design and implement their research, and then plan a service project based on research findings to address the issue. We explored young people's and educators' perspectives on which project elements influenced youth participation, examined opportunities for youth science and civic-related learning, and asked educators to reflect on their own learning and development. Using data generated from youth focus groups and educator interviews, we found that YPAR grounds science learning in young people's lived experience. It also provides a meaningful approach to science learning through raising young people's critical consciousness of community issues. YPAR may be used in other extension programs to increase motivation for deeper and sustained participation in learning experiences.","PeriodicalId":9409,"journal":{"name":"California Agriculture","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45581176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines how agritourism operators responded to the challenges and opportunities created by the pandemic. In 2021 and 2022, in the midst of the pandemic, the UC ANR Agritourism Program held a series of trainings for California farmers interested in starting or expanding agritourism enterprises. Some of the key themes that emerged from the trainings were that farmers had to shift their operations to ensure social distancing and reduced crowd sizes, while at the same time, they experienced an unprecedented demand for direct-to-consumer sales and on-farm visits. Agritourism, in varying degrees, contributed to the resiliency of most of the participants in our study. Moving forward, it would be worthwhile for researchers, agricultural professionals, and decision-makers to examine equity in agritourism and agritourism's role as a risk-management strategy to help mitigate other types of disruptions in the future. Our findings also point to the need to provide farmers with technical assistance around e-commerce and sustainable business planning.","PeriodicalId":9409,"journal":{"name":"California Agriculture","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42710355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is challenging to estimate the size and distribution of these costs in today's complex supply chains. Extensive use of formal contracts in markets such as leafy greens obscures prices and other terms of trade from the public view. Using proprietary data on prices and sales from a major leafy greens processor operating in the retail and food-service sectors, we are able to separately estimate short-run damages associated with the November 2018 romaine Escherichia coli advisory for growershippers, processors, retailers, and food-service operators. Due to fixed prices in grower-processor contracts, growers were only minimally impacted by the advisory. Processors, meanwhile, lost approximately $55.3 million from price and quantity impacts. Retailers incurred $14.1 million in losses after pulling product from distribution channels and shelves. Foodservice operators were less impacted because lower prices offset losses from destroying potentially contaminated products. Moving forward, the best way to mitigate losses during food-safety incidents is fast and efficient traceability.","PeriodicalId":9409,"journal":{"name":"California Agriculture","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49452249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, some farmers are hesitant to try these conservation practices due to uncertainty about whether planting winter cover crops will deplete soil moisture in already drought-stricken regions. Our study addresses these concerns by looking at how long-term reduced-disturbance tillage and winter cover cropping, compared to fallowed soils with standard tillage, affected soil moisture. Although we found a statistical difference in total soil water content, the difference was only about 0.3 inches of water per foot of soil. On average, the soil water content of the top 0–96 inches was highest for the reduced-disturbance fields with winter cover crops. This was especially evident during our driest field season, from November 1, 2017, to March 15, 2018, when cumulative rainfall was only 1.9 inches. Our findings show that winter cover cropping and reduced-disturbance tillage can improve soil without depleting soil water levels in row crops.","PeriodicalId":9409,"journal":{"name":"California Agriculture","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49258501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This can pose health threats to humans and animals. This risk, along with alterations of essential minerals in livestock grazing on regrowth on burnt lands, is not well known. To better understand this, our study investigated metal concentrations in water, soil, plant forage, and meat and wool of sheep grazing on the regrowth of burned lands. We compared metal concentrations in sheep grazed on regrowth to stored meat samples from grazing sheep a year prior to the wildfire. Lead, mercury, arsenic, molybdenum, cadmium, beryllium, cobalt and nickel were not detected above reporting limits in meat, wool or water samples. Contamination from chromium and thallium was detected in three of 26 meat samples from sheep grazed on regrowth. These metals were not detected in 22 stored meat samples from sheep the year before. Copper concentrations found in the meat of animals grazing regrowth was lower than in animals grazing unburned pastures; it is important to monitor copper concentrations in grazing animals to avoid diseases associated with copper deficiency.","PeriodicalId":9409,"journal":{"name":"California Agriculture","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43623448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
