The 20th GiESCO International Meeting is held in Mendoza (Argentina), November 5-10, 2017.
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.
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.
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.
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.
In agriculture including viticulture demand for organically grown crops has developed exponentially in the last few decades. Particularly in the wine sector organic and biodynamic management system are gaining more and more importance and some of the most prestigious wineries have converted to organic or biodynamic viticulture.
Sustainability is a broad concept, and its economic component is not often incorporated when sustainable farming practices are studied. This study analyses some economic parameters related to the size of vineyard operation as individual business or associated with a winery.
Herbicides are commonly applied under vines to minimize the competition by weeds. As concerns about using fewer chemical inputs have developed, alternative methods to herbicides for undervine weed control are increasingly being adopted. These trials were carried out in New Zealand on Sauvignon blanc, Pinot noir, and Merlot from 2012/13-2015/16.
In the context of climate change and the complex terrain of the Western Cape, increased resolution of climate data is crucial for effective adaptive strategies. Reliable climate data can be costly, and currently requires intensive data validation; hence the study aimed to find an alternative resource to quantify the climate over the spatial extent of the Western Cape, for possible semi-real time applications.
São Joaquim (28º17'38 "S and 49º55'55" O) is a viticultural region located on the Santa Catarina Plateau, south region of Brazil, which is known for vineyards that produce fine wines from grapes cultivated at altitude (> 900 m). It is amongst the coldest (annual average of 13.42 ºC, 1832.36 hours of solar radiation and 1680.23 mm of precipitation) and the highest (715 - 1638 m) Brazilian’s viticultural regions, with hilly relief (43% of slopes between 20 - 45% of declivity, with no preferred direction).
Winegrape production is largely controlled by climate conditions. Identifying how climate conditions impact on vine allows for identifying the suitability of a specific variety for a given region. Given the relevance of the Malbec wine production in Argentina, this study is devoted to derive a Unique Combined Index (UCI) for assessing the suitability of Malbec grape production (MGP) in Argentina.
