(OIV) - The International Organisation of Vine and Wine (OIV), the intergovernmental reference organisation for everything related to vine-based products, unveiled its report on the global economic vitiviniculture situation for the first ten months of 2011. Federico Castellucci, the OIV Director General, presented the economic data available at the end of October 2011, in order to provide an estimate of the trends in the areas under vines as well as the level of wine production worldwide. The world vineyard area experienced a decrease that could reach 60 mha (7.8 Mha). By zones, the EU is most affected by this phenomenon, since the reduction in its vineyard could be between 50 and 55 mha (-1.4%/2010; 3570 mha). Furthermore, in the Southern Hemisphere and the USA, the rate of surface area growth has slowed, compared with what was observed around 2000.
