Valuation of Viticultural Adaptation to Climate Change in Vineyards: A Discrete Choice Experiment to Prioritize Trade-Ofs Perceived by Citizens

On a climate change scenario, a discrete choice experiment was applied to elicit the trade-of values for three environmental impacts of current viticultural management practices in vineyards of Mendoza, Argentina. Water availability for other uses was found to be the most concerning topic for the population, followed by use of chemical fertilizers and then by use and conservation of biodiversity. An increase of one percentage point in water availability was estimated to add each citizen on average 13.05 Argentinean pesos – 0.74 US dollars – per year in terms of increased welfare, a figure equivalent to the welfare drop a citizen would experience after an increase of 1.45 percentage points in the use of chemical fertilizers annually per hectare, or a decrease of 2.69 percentage points in the use and conservation of biodiversity. These trade-of values may help policy makers, planners, regional managers, and ecologists to take social preferences into account in setting resource allocation priorities intended to support viticulture. This study approach provides a framework that could guide similar assessments in other regions. Fil: Farreras González, Verónica Inés. Consejo Nacional de Investigaciones Científicas y Técnicas.
