Meso-scale future climate modeling (5 km resolution): application over French wine regions under the SRES A2 scenario (2041-2050)

Abstract

In order to assess climate change at regional scales suitable to viticulture, the outputs of ARPEGE_Climat global model (resolution 0.5°) were downscaled using the Regional Atmospheric Modeling System (RAMS) and nested grids, providing downscaled datasets of 5 km resolution over France. Simulations were performed for two periods: 1991-2000, to assess the method against observations and quantify the large-scale induced biases; and 2041-2050 as near future climate projection under the SRES A2 scenario conditions. Results for July maximum temperatures, focussing on 6 wine regions, show RAMS contribution in reducing the large-scale bias, leading to a better assessment of climate change, yet with spatial differences.

Correlation between grape and wine quality, landscape diversity, on-field biodiversity, in doc gioia del colle, italy

Analysis of aerial photos by using GIS tools and on-field surveys of flora are used to characterize territories from an agro-ecological point of view and to assess the level of diversity of given agro-ecosystems. More and more correlations between landscape characteristics, sustainability and quality of agriculture production were speculated. In last three years a study was carried out in the area of DOC “Gioia del Colle” in Apulia, South Italy, in order to characterize and investigate different vineyards and sites and find out possible interactions and correlations between the landscape diversity, the biodiversity of fields and the quality of grapes and wines.

Study of the fruity aroma of red wines through perceptual interactions among volatile compounds in the context of climate change for the Bordeaux vineyard

The fruity aroma of red wines is described by a wide range of descriptors, ranging from fresh fruits to ripe and jammy fruits, to candied fruits and prunes notes [1]. The fruity quality of a red wine is characterized by notes of fresh and jammy red- and black-berry fruits.
