 Analysis of California agricultural issues

The University of California Agricultural Issues Center (AIC) is a statewide program within UC Agriculture and Natural Resources.
We study topics such as international markets, invasive pests and diseases, the value of agricultural research and development, agricultural policy and the rural environment among others. The issues are often global, but we emphasize implications for agriculture and natural resources in California. The audience for AIC research and outreach includes decision makers in agriculture and government, scholars and students, journalists and the general public.

Port Slowdown Impacts California Agriculture.
Georgi T. Gabrielyan and Daniel A. Sumner. ARE Update, Vol. 18, No. 4, 2015
The West Coast port delays that began in the summer of 2014 and lasted until near the end of February 2015 cost California agriculture dearly. As the delays extended into the winter, citrus exports were hit while exports of storable crops to Asia also slowed. The story for wine is more complex, because California both imports and exports wine through West Coast ports.

Public Universities and Region Growth:  Insights from the University of California
.book cover
AIC researchers Jim Lapsley and Dan Sumner have just published a book chapter, "We Are Both Hosts," that highlights the synergistic interaction between Napa wine industry and the University of California, Davis. Their research appears as a chapter in the new book, Public Universities and Region Growth: Insights from the University of California, which was recently published by Stanford University Press. The chapter “We Are Both Hosts”, examines agricultural innovation by focusing on the interaction between Napa valley wineries and vineyards and the U.C. Davis Department of Viticulture and Enology. Tracing the growth in the production of and market for quality wine, the chapter reviews the development and adoption of viticultural and enological innovations from the 1950s to the present and analyzes the effects of U.C. Davis outreach, teaching and research.
