I'm looking for information on California's agricultural labor. Using the 'California Farm Labor: The ALRA at 50 - Summary Report' on the Events page, identify the key economic challenges facing the sector. Also, provide the average number of workers employed and the 2023 ratio of unique workers to full-time equivalent farm jobs.
Navigate to the 'Events' page on migration.ucdavis.edu. Locate and review the 'California Farm Labor: The ALRA at 50 - Summary Report' content on the page. Identify and list the three major economic challenges discussed in the report. Extract the average number of workers employed in California agriculture. Extract the ratio of unique workers to full-time equivalent jobs in California agriculture for 2023. Synthesize the extracted information into a concise answer.
State the three major economic challenges facing California agriculture as mentioned in the report: a precarious economic position (due to overproduction, economic and trade uncertainty, rising labor costs, new groundwater regulations, and declining value of orchards and vineyards); increasing farm labor costs faster than nonfarm labor costs (leading to mechanization, building housing for H-2A workers, and switching crops); and limited unionization prospects (with NGO worker centers and private certification systems proliferating as alternatives). State that an average of 400,000 workers are employed in California agriculture. State that the ratio of unique workers to full-time equivalent farm jobs in California agriculture was 2 or more in 2023.
