Climate Change Literacy in Postsecondary Horticultural Education in the United States

Horticultural crops are being affected by weather extremes consistent with predictions from climate change models. Impacts include crop losses and extended growing seasons. Negative effects on crop productivity are predicted to vastly overwhelm any positive effects. Students who graduate from our programs will need additional knowledge to succeed compared with those trained in previous decades. To determine the extent to which higher educational institutions across the United States are educating students about these issues, a survey was conducted to gather information on the incorporation of climate change literacy in horticultural curricula. Most programs do not currently offer classes with “climate change” or “global warming” in the formal title or description, but many instructors are including at least some information related to climate change in specific courses they teach. Instructors of courses in fruits, vegetables, or turf, and instructors who do not teach at 1862 land-grant universities, are more likely than other instructors to include content related to climate change in their courses. Instructors who do not have tenure and instructors who teach plant identification courses are more likely than other instructors to have increased the content on climate change in their classes over time.
