“…ET 0 ) (Figure 1a) compared to the corresponding value for the historic climate (Figure 1b). A similar decrease in average APET under future climate projections was reported for South Australia during the same period in a study involving 100 ensembles of the GFDL‐ESM2M climate model for RCP 8.5 (Phogat et al 2018). This shows that the inter‐annual variations in the median projections used in this study emulate the possible uncertainty in large ensembles of the future climate data.…”

“…The estimated mean I for grapes in different soils under the future climate (2018–2050) showed an increase of 3.5–5.8% (396.9 ± 32.4 mm) compared to the historical climate (1970–2017) values (374.0 ± 39.9 mm) (Table 3). Phogat et al (2018) reported a 4.5% increase in the winegrapes I for Riverland (South Australia) conditions during 2020–2039. Sen's slope median estimator ( Q med ) of annual I values also showed a similar increase in the mean I for future climate, corroborating the validity of the statistical estimator.…”

Apart from direct impact, a hotter and dryer climate can increase the danger of associated environmental problems such as an increase in soil salinity (Phogat et al 2018) and resultant soil degradation. Although grapevines show a strong resilience to challenging environmental conditions (van Leeuwen and Darriet 2016), estimating long‐term trends in irrigation requirements and soil water balance, including evapotranspiration (ET) components (ET, transpiration, evaporation, drainage) of vine under varied soil textures, can provide practical information to inform sustainable production and ensure that yield and quality can be maintained.…”

Background and Aims An understanding of the dynamics of the components of evapotranspiration and irrigation requirements in response to climate variation and change is essential to manage vineyards sustainably. Methods and Results Winegrape evapotranspiration (ETC adj), seasonal transpiration (Tp adj), soil evaporation (Es) and irrigation requirement (I) were evaluated with the FAO‐56 dual‐crop coefficient, across a range of soil types, in response to historical (1970–2017) and future (2018–2050, Representative Concentration Pathway 4.5) climate projections. The Mann–Kendell non‐parametric test and Sen's slope were used to detect any trends regarding historical and future climate. A statistically significant increasing trend was observed in the annual ETC adj, Tp adj and I under both climate scenarios, and Es showed a significant negative trend for the historical projection. Average daily ETC adj ranged from 1.2 to 4.3 mm under historical climate and increased to 1.5–4.6 mm under the future climate projection. Estimated I was 240–528 mm depending on the soil type and rainfall during the growing season, with the largest increase in irrigation predicted during October and November. Conclusions The increase in irrigation requirements was within half a standard deviation of historic values, and the largest increase did not coincide with the months of maximum demand. Significance of the Study The predicted increase in irrigation requirements is likely to be within the adaptive capacity of the existing infrastructure and growing systems but will need ongoing monitoring as climate projections are revised.

“…The development of high water-use efficiency systems in areas previously not irrigated still results in an increase of total water use. The second aspect deals with salinity problems, which appeared first in countries like Israel and Australia (Phogat et al, 2018 ). Model simulations indicate a steep increase of salinity in the root zone as rainfall-induced salt leaching declined significantly with climate change.…”

Evaluating Strategies for Adaptation to Climate Change in Grapevine Production–A Systematic Review

et al. 2021

In many areas of the world, maintaining grapevine production will require adaptation to climate change. While rigorous evaluations of adaptation strategies provide decision makers with valuable insights, those that are published often overlook major constraints, ignore local adaptive capacity, and suffer from a compartmentalization of disciplines and scales. The objective of our study was to identify current knowledge of evaluation methods and their limitations, reported in the literature. We reviewed 111 papers that evaluate adaptation strategies in the main vineyards worldwide. Evaluation approaches are analyzed through key features (e.g., climate data sources, methodology, evaluation criteria) to discuss their ability to address climate change issues, and to identify promising outcomes for climate change adaptations. We highlight the fact that combining adaptation levers in the short and long term (location, vine training, irrigation, soil, and canopy management, etc.) enables local compromises to be reached between future water availability and grapevine productivity. The main findings of the paper are three-fold: (1) the evaluation of a combination of adaptation strategies provides better solutions for adapting to climate change; (2) multi-scale studies allow local constraints and opportunities to be considered; and (3) only a small number of studies have developed multi-scale and multi-lever approaches to quantify feasibility and effectiveness of adaptation. In addition, we found that climate data sources were not systematically clearly presented, and that climate uncertainty was hardly accounted for. Moreover, only a small number of studies have assessed the economic impacts of adaptation, especially at farm scale. We conclude that the development of methodologies to evaluate adaptation strategies, considering both complementary adaptations and scales, is essential if relevant information is to be provided to the decision-makers of the wine industry.

“…Several studies addressed future evapotranspiration modelling under climate change (Kingston et al, 2009;Xu et al, 2014;Obada et al, 2017). There have been several studies made concerning irrigation and drought problems in viticulture (Chaves et al, 2007;Zsófi et al, 2008;Van Leeuwen & Darriet, 2016;) nevertheless, only a few studies analyse drought and WR using future climate change scenarios, namely (Kingston et al, 2009;Fraga et al, 2017;Obada et al, 2017;Phogat et al, 2018) and a study in Spain (Cancela et al, 2016). There are interesting studies on the effects of water stress due to a rise in temperature on the grape variety Tempranillo in Mediterranean summer conditions (Flexas et al, 1999) and on the Semillon grape variety (Winkel & Rambal, 1993).…”
