Research concerning the economic impact of climate change upon grape production.

Abstract

The paper aimed to analyse grape yield, production and quality due to climate conditions in the years 2007 and 2008 at Bujoru Vineyard. Experiments were carried out on 11 vine types both for red and white wine grapes and table grapes as well (Feteasca alba, Feteasca regala, Aligote , Sarba, Cabernet Sauvignon, Merlot, Babeasca neagra, Feteasca neagra, Chasselas Dore, Hamburg Muscat and Coarna neagra selected). The Index Method, Gain Method, Share Method, Comparison Method, Point Method have shown the evolution and importance of 22 climate factors and their influence upon grape yield, production and quality from a year to another and among the 11 vine types. The increased level of climate factors in 2008 compared to 2007 determined an increased acidity, grape weight and volume, but a decreased sugar content for almost all the vine types.
