Hoemmen, Garrett | Altman, Ira | Rendleman, Matt
Winegrape productivity and quality are important characteristics in the production of superior wines and efforts to maintain these features have potential environmental impacts. Agricultural adjustments and conservation initiatives that anticipate potential harmful impacts are essential for sustainability. Recent attempts to institute practical sustainable practices for the production of wine include the Lodi Rules for Sustainable Winegrowing. Our research examined the effects of this program over time. Did sustainable viticulture initiatives that focus on both social and environmental issues also translate into economic success? In order to investigate the economic impacts of the Lodi Sustainable Viticulture initiatives the relationship between weighted average price per ton and sustainable development variables, are investigated in are regression model. The model relies on a time series analysis using California Crush Reports from 1976 to 2012 (NASS 2012). We found the publication of the Lodi Rules Workbook exhibited the most substantial effect (−$232.87). This effect was negative; therefore our hypothesis that most positive economic effect was confirmed as the implementation of the Sustainable Winegrowing Program, produced an added benefit of $98.28 over time.
