New research reports on California winegrape grower adoption of sustainability practices


By Matthew Hoffman - Posted on 20 October 2012

This week the Center's viticulture research team released two complementary reports about California winegrape grower adoption of sustainability practices and vineyard management goals. Several organizations throughout California viticulture share the objective of encouraging winegrape grower adoption of sustainability practices through outreach. "Sustainability practices" are those that balance economic, environmental, and social costs and benefits. We considered 44 codified sustainability practices. In these reports we focused on two organizations: the Napa Valley Grapegrowers and the Central Coast Vineyard Team. Both organizations have established histories of sponsoring grower outeach activities including field research, informational meetings, industry fairs, sustainability self-assessment workbooks, and sustainability certification systems. These reports present results from a mail survey of winegrape growers in the Napa Valley and Central Coast American Viticulture Areas, which collected data on whether they have adopted sustainability practices, what impact regional and statewide outreach activities have had on growers' practice adoption, and whether or not growers’ vineyard management priorities reflect sustainability objectives. One of the most important findings (in both regions) was a positive relationship between grower participation in sustainability outreach activities and sustainability practice adoption. On average, the more a given grower participated in outreach activities, the more likely they were to adopt sustainability practices. We believe that these results justify continued support for sustainability-oriented outreach. The reports are included below as attachments.
