“…Mosedale et al () hypothesised better conditions (more thermal resources) for grapevine growth in southern England under future climatic scenarios, concurrently highlighting the persistent risk of frost damage. In Spain, Resco et al (), analysing current and future changes in climate at regional level, highlighted different responses in a generalised context of warming and proposed different adaptation strategies.…”

Background and Aims The growth and development of grapevine is constrained by temperature, affecting the bulk of physiological processes of the plant. The aim of this study was to evaluate the effects of climate change on thermal resources and limitations in the context of Georgia, one of the oldest viticultural areas in the world. Methods and Results The analysis on daily series of temperature for the time period 1974–2013 for the main viticultural areas of Georgia shows that an abrupt change to warmer temperature occurred in 1994, leading to a decline in low temperature stress and an increase in high temperature stress, associated with more frequent heat waves. The availability of thermal resources for grapevine growth remained unchanged. Conclusions In Georgia, the shift to warmer temperature did not affect the availability of thermal resources for grapegrowing. Although some attention should be paid to possible damage due to an earlier budburst and increased frost risk. Furthermore, it is important to highlight the strong increase of summer heatwaves with potential negative impacts on grape composition and phenolic maturity, when combined with severe water stress. Significance of the Study Quantitative studies of the effects of climate change on Georgian viticulture are essential to develop adaptation strategies based on either germplasm (e.g. rootstocks and cultivars) and agronomical practices (e.g. pruning, trellis systems, soil and water management).

“…Global warming above 2 • C (with respect to the pre-industrial era) may involve very important changes in Mediterranean ecosystems, such as a loss of biodiversity, reduction of forest areas, and the expansion of desert areas (increased desertification in southeastern Spain), as well as bringing major risks to the population as a result of scarcity of water resources and an increase in the demand for water for irrigation, energy, and domestic use [4]. As regards wine production, according to climatic projections for Europe and Spain [3,5], the southern regions of Europe and the Mediterranean arc, especially the South and East of the Iberian Peninsula, will need the most effort in order to adapt, with increased costs to maintain the quality and productivity of vineyards, since these regions will face changes of greater magnitude than other wine-producing areas [6]. For example, a study conducted to explore the possible measures of adaptation to climate change in several Spanish wine-producing regions points to the fact that the Protected Designation of Origin (PDO) of Jumilla and La Mancha are two of the most vulnerable, and that they may suffer a high impact due to a great increase in the projected temperature and a decrease in precipitation [6].…”

In many areas of southern Europe, the scarcity of water due to climate change will increase, making its availability for irrigation an even more limiting factor for agriculture. One of the main necessary measures of adaptation of the vineyards in these areas will be the implementation of water-saving irrigation strategies and technologies to improve WUE (water use efficiency). The objective of the present study was to evaluate the long-term economic viability/profitability of different deficit irrigation techniques such as regulated deficit irrigation (RDI) and partial root-zone irrigation (PRI) with low water volume/fertilizer applied in a Monastrell vineyard in southeastern Spain to plants grafted on different rootstocks, and to assess the productive, social, and economic efficiency in these semiarid conditions. Through a cost/benefit analysis, socio-economic and environmental criteria for the selection of optimal deficit irrigation strategies and tolerant/water use efficient rootstocks for the vineyards in arid environments are proposed. Our analysis shows a clear conflict between productivity and quality in wine grape production. Productive and economic indices, such as yield, productive WUE (kg m−3), economic efficiency (€ m−3), break-even point (kg ha−1), and water productivity (€ m−3), were inversely related with berry quality. Besides, high berry quality was closely related with higher production costs. Under the current market of low-priced grapes, if the grower is not rewarded for the quality of the grapes (considering technological, phenolic, and nutraceutical quality), the productivity vision will continue and the cost-effective option will be to produce a lot of grapes, even if at the expense of the berry and wine quality. In this situation, it will be difficult to implement optimized deficit irrigation strategies and sustainable irrigation water use, and the pressure on water resources will increase in semiarid areas. Public policies should encourage vine growers to invest in producing high-quality grapes as a differentiating character, as well as to develop agronomic practices that are environmentally and socially sustainable, by the grapes more adjusted to their real quality and production costs. Only in this way we can implement agronomic measures such as optimized low-input DI (deficit irrigation) techniques and the use of efficient rootstocks to improve WUE and grape quality in semiarid regions in a context of climate change and water-limiting conditions.

Background and Aims: Spain has more than one million hectares of vineyards, being the first country in the world, and the third in production of wine. Local zoning studies have been carried out using bioclimatic indexes to show the influence of climate; however, no detailed study has been undertaken at national level that included the current area of vineyards. The aim of this study was to prepare a thermal characterisation and zoning of winegrowing areas in Spain through four bioclimatic indexes. Methods and Results: From data of the European Climate Assessment & Dataset (1980, four bioclimatic indexes adapted to viticulture were calculated and integrated into a geographic information system, which allowed the graphical visualisation of their patterns by means of geostatistical interpolation techniques (kriging). The results show that there is a significant spatial variability of the climate from a winegrowing perspective, and each index defines the differences between the climatic classes suitable for viticulture. Conclusions: In order to define and assess the climatic differences in wine production and the suitability of the Spanish mainland territory, it is necessary to combine several indexes. Significance of the Study: For the first time, the climatic variability of Spain has been described and the peculiarities that differentiate its vineyards have been highlighted. High-resolution kriged maps have made this study possible.
