Effects of Climate Change on Viticulture (Grape)

Topic Information

Dear Colleagues,

Climate change has many negative effects many countries economic sectors and viticulture is no exception. Temperature, drought, heat waves, new emerging diseases are some of the effects of climate change that negative impact in both on plant growth and product quality. Within the abiotic factors, drought stress is one of the major challenges, increasing the need to develop water stress resistant plants as well as new strategies (eg tailoring vineyard microbiome) to increase plant access to water. Climate change shows its impact in many different ways, within biotic stress, new emerging diseases as well as new outbreaks of well-established diseases create new challenges for viticulture, particularly when the reduction of pesticide application in the vineyards is a demand. Viticulture is one of the most polluting industries and thus the development of disease tolerant crossing hybrids, the identification of new molecules that prime grapevine immunity as well as the development of regenerative agriculture pratices are crucial New varieties that can adapt to changing climatic conditions urgently need to be developed with the help of modern techniques. However, in these studies, there is a need to develop stress-resistant species and varieties, rather than transgenic varieties, with marker-based selection and other identification techniques, paying attention to ethical issues as much as possible. In addition, in accordance with the increasing environmental and human health awareness, it is necessary to realize all these in accordance with the sustainable agriculture model.

The steadfast propensity to global warming has had a severe impact on overall viticulture. Given the observed increase in growing season temperatures in Europe (+1.7 °C from 1950 to 2004), between 2000 and 2049, it is assumed that temperatures for major wine regions [...] Read more.

The steadfast propensity to global warming has had a severe impact on overall viticulture. Given the observed increase in growing season temperatures in Europe (+1.7 °C from 1950 to 2004), between 2000 and 2049, it is assumed that temperatures for major wine regions will increase on average by about +0.42 °C per decade and will generally increase by +2.04 °C. Phenolic compound development is affected by environmental parameters such as ultraviolet (UV) radiation, sunlight, maximum and minimum temperatures, and grapevine water status. Proanthocyanidins, flavan-3-ol monomers, and other pigmented polymers are impacted by soil management and canopy handling strategies, as well as obtaining a microclimate around the developing bunch. This review, after a necessary summary of the synthesis of phenolic compounds in the berry (flavonoids and non-flavonoids) to let the lector delve into the topic, describes the impact of climate change and therefore of environmental factors on their accumulation and storage throughout ripening and harvesting. For example, high berry temperatures can reduce the total concentrations of skin anthocyanin; a 35 °C temperature entirely obstructed anthocyanin synthesis, and instead quercetin 3-glucoside could be enhanced with exposure to solar radiation. In addition, increments via water deficit in the relative abundance of methoxylated anthocyanins were also found. The vineyard management strategies to mitigate the degradation of phenolic compounds and preserve their concentration are also further discussed. Finally, it is believed that it is necessary today to establish an elastic and variable approach towards the single wine year, moving away from the concept of product standardization. Full article
