“…When comparing HI and WI, clear differences were found between the two bioclimatic indices in terms of the JD needed to reach the optimum of 2200. In particular, more JD were needed to reach at least 2200 WI than to reach 2200 HI, which is in line with Navrátilová et al (2021), but with more fluctuations. These differences are mainly related to the periods that the formulas were based on: HI was based on the period of 1st April to 30th September, while WI was based on the period 1st April to 31th October, with the period of calculation ending after harvest.…”

Climate change in a typical Apulian region for table grape production: spatialisation of bioclimatic indices, classification and Future Scenarios

2021

The present research focused on the characterisation of climate evolution in a typical Apulian region for table grape production under the protected geographical indication, “Uva di Puglia I.G.P.”Two thirty-year time window period (TW) were analysed: 1961-1990 and 1991-2020. Georeferenced maps for both TWs were produced to delimit homogeneous zones and to evaluate the climate variability within the investigated area by means of the two bioclimatic indices, Heliothermal Index (HI) and Winkler Index (WI). Spatial analysis of HI and WI was performed using the regression-kriging (RK) interpolation method and the Digital Elevation Model/DEM (10 x 10 m) as a prediction attribute.An increase in both the minimum and maximum temperatures was observed, and locations above 300 m a.s.l. shifted from HI+1 “temperate warm” to HI+2 “warm” according to the Geoviticulture Multicriteria Climatic Classification System. WI values similarly increased between the periods 1961–1990 and 1991–2020, shifting all the sites grouped in the Elevation Classes defined as being below 300 m a.s.l. from Region IV to Region V of the Winkler Classification.According to HI and WI, presumed maturity was calculated as being reached 9 to 15 (HI) and 12 to 28 days (WI) earlier in 1991–2020 than in 1961–1990, taking into account the heat requirements of cv. Italia table grape (representative of Apulian table grape production), were set at 2200 for both indices on the basis of literature data.Moreover, three table grape vineyards, located in the three main producing provinces of Apulia (Bari, Taranto and Barletta-Andria-Trani (BAT)), were considered for future scenarios analysis on the basis of two different Representative Concentration Pathways (RCPs), 4.5 and 8.5, and classified according to the Geoviticulture Multicriteria Climatic Classification System (MCC). Future scenarios scored WI values that exceeded the threshold of 2700 in the BAT and TA provinces in the 2061–2090 time window period for RCP 8.5. In contrast, RCP 4.5 led to a mitigating effect, which was not noticeable until 2040, with a consequent reclassification of the investigated areas on the basis of HI and Cool Night Index (CI).These findings suggest that in order to prevent or overcome heat stress, it will be necessary to implement strategies, such as vineyard relocation to unexplored elevations or latitudes and/or the exploitation of new table grape varieties able to fulfill the optimal maturity parameters, even when the duration of the phenological phases is shorter.

“…This conclusion is in general agreement with Van Leeuwen and Darriet [38], who argue that agriculture is highly dependent on climatic conditions during the growing season of crops, which also significantly affects world crop production. These finding were confirmed by Koch and Oehl [39] directly using the example of vines [40]. Current, confirmed, and ongoing climate change mainly affects the volume of production, the sugar content, and, thus, the quality of the finalproduct wine.…”

“…The results can be interpreted as meaning that if, at the current values and average development of total precipitation, precipitation increases during the growing season of grapes by 1 mm, then the annual production of grapes will decrease on average by 896,976 CZK, and if the average annual temperature in the growing months increases by 1 • C, then the value of grape production will increase on average by 77,293,737 CZK. The increase in grapes' sugar content in the Czech Republic was also confirmed during the period under review, which will need to be taken into account in further production [40].…”

The warming of the planet and ongoing climate change are now a scientifically proven fact. These phenomena have an impact on nature and many human activities, but logically affect agriculture the most. History has confirmed that the production of grapes (the extent and quality) is significantly affected by climate change. The main goal of this study was to evaluate the impact of climate change through changes in average precipitation and average temperatures on the quantity of grape production in the Czech Republic. A partial goal was then to predict the future development of grape production depending on the expected total precipitation and average temperatures. The effect of changes in average temperatures and total precipitation was evaluated using multiple linear regression methods. The multiple regression model did not reveal a dependence of the total precipitation and average temperatures on the development of the value of vine production due to the statistical insignificance of the effect of average temperatures on the value of vine production. However, when abstracting the effect of average temperatures on the value of vine production, the research confirmed the effect of the change in total precipitation on the value of vine production. The analysis identified the effect of changes in total precipitation and temperatures on the production of grapes in the Czech Republic.

“…Quite a different pattern can be found in the Czech Republic which has always been a traditional beer-drinking country. However, the wine consumption per capita for the Czechs has more than tripled from 6 liters per capita (Navrátilová et al, 2021).…”

For centuries, wine has played an important role in the economic institutions of food security and agri-food complex. However, due to the globalization and economic development wine industry has been in the midst of a number of changes and new challenges in recent decades, to which it is forced to respond in order to maintain its competitiveness and economic efficiency. Changing consumer preferences and requirements lead to the changes in wine consumption around the world. New territories enter the wine market, which modifies the institutions and the mode of the wine trade from a global perspective. All these aspects resonate with the climate change. Wine as a crop is highly sensitive to climatic and soil conditions which results in the extraordinary sensitivity of the entire viticulture and wine-making sector. Our paper evaluates wine consumption in selected European countries and Russia in the context of climate using the beta convergence method. Beta convergence was used as research method, through which changes in differences between selected countries whose consumption exceeds 2 million hectoliters were examined. The basic sample consisted of 14 countries from Europe and Russia. The results show that globalization processes are blurring some of the differences between countries, which are converging in terms of wine consumption in the long run. At the same time, however, it can be stated that the influence of natural conditions and historically given peculiarities cannot be disregarded. National customs are also historically adapted to the climate, including the preferred types of beverages.
