The United States' broccoli supply faces a significant threat from looming California droughts, according to new research. Broccoli, considered America's favorite vegetable, is overwhelmingly grown in California, which produces over 90% of the nation's fresh broccoli.
A study published in Agribusiness by researchers from Cornell University analyzed 20 years of shipping records and federal drought data. The findings indicate that a severe drought in California could lead to a 20% drop in broccoli shipments, while a moderate drought could result in a 9% decrease.
Since 2000, water shortages in California have already impacted broccoli crop yields and the amount of land dedicated to its cultivation. Bingyan Dai, a Cornell researcher, stated that while California remains crucial for the nation's fresh produce, increasingly frequent drought events in the state are affecting broccoli production and consumer access.
To mitigate these risks, researchers suggest diversifying broccoli production by expanding cultivation to the East Coast. This geographical shift could potentially reduce supply chain costs by approximately $10 million in a severe drought scenario. The study indicates that growing broccoli on the East Coast could enhance the resilience of the country's supply chain without substantially increasing costs.
However, some industry representatives, like Christopher Valadez, president and CEO of the Grower-Shipper Association of Central California, have cautioned against alarm. Valadez pointed out that California's growing regions have successfully supplied the nation with broccoli even during past drought periods, citing the state's adaptive capacity and quality advantages.
Despite these assurances, the research underscores the importance of a diversified supply chain. While California is expected to remain a vital broccoli-producing region, incorporating East Coast production could create a more robust system for ensuring consistent access to the popular vegetable for American consumers.
