Current climate change sceneries represent a menace for grapevine production. Models have estimated than in the middle of the century temperature will increase aprox. 2°C.
Global warming, and the ongoing expansion of viticulture to marginal areas is increasing the surface area of vineyards experiencing high solar irradiance and daily temperatures, leading to the loss of quality-related compounds.
Drought and high temperature are important threats to plant growth and sustainable agriculture worldwide.
Soil water availability is one of the main determinants of crop yield and of adaptation to a changing climate. The aim of this study was to analyse the soil water regime, as determined by climatic conditions, in combination with the intra-specific biodiversity of yield responses of grapevine to water availability. The adaptability of wine-producing cultivars to future climate was thus assessed.
The IPCC has created several climate scenarios evaluating the impacts and consequences of climate change. All agricultural sectors will be concerned, in particular grape and wine production. Climate, especially temperature, has a key role in grapevine development.
Two main challenges of a changing climate are the increase in atmospheric carbon dioxide (CO2) and temperature in relation to physiological responses and yield performance of plants. To investigate responses of field grown grapevines under elevated CO2 (+20 %) conditions a FACE (Free Air Carbon dioxide Enrichment) facility for Vitis vinifera cvs. Riesling and Cabernet Sauvignon was established at Geisenheim (50°N, 8°E, Germany) in 2012.
The few studies that relates the chemical composition and the organoleptic characteristics of Argentine wines with the origin show that climate is a very important factor.
In this study, dates of vine developmental stages and harvest dates of eight winegrape varieties in two major wine producing regions of North Greece (Kavala and Naoussa) were gathered. Data of the basic developmental stages (budburst, flowering and veraison) for three varieties in Naoussa covered a period of 8 years while harvest dates observations ranged from 13 to 35 years for eight varieties in both regions.
Over a wine region, the knowledge of climate variability is primordial to contribute to adaptation issues to climate change (CC). Interviews were carried out using the method developed in TERADCLIM Project to evaluate winegrowers perception of CC and ways of adaptation.
