Abstract

Climate change is severely impacting viticulture in the southern Mediterranean, particularly in regions like Campania, Italy. This study investigated the effects of climate change on Greco, a native grape cultivar, by examining the relationship between water balance and grape quality to provide practical support to farmers.

A three-year field experiment was conducted in a vineyard owned by Feudi di San Gregorio winery in Santa Paolina (Avellino, Italy) employing various soil and canopy management practices. The data collected were used to calibrate and validate the SWAP agro-hydrological model, analyze the soil-plant-atmosphere system, and evaluate the impacts of climate change scenarios (RCP 4.5 and 8.5) on grape quality. Results showed that managing water stress is crucial for achieving the desired grape quality, with the required level of °Brix, in particular during veraison when crop water stress index (CWSI) reaches values below 20 %.

When the expected climate change is considered using a simulation modelling application, in the periods of 2010–2040, 2040–2070, and 2070–2100, significant rise in water stress is expected with an increase on average by 7 %, 9 %, and 8 % respectively in the RCP 4.5 scenario and 4 %, 9 %, and 14 % in the RCP 8.5 compared to the Reference Climate (RC).

This research provides practical support for farmers adapting to climate change and ensuring the resilience of Controlled and Guaranteed Designation of Origin areas. The study was part of the GREASE project funded by the Campania Region, focusing on sustainable cultivation practices for Greco.

希腊葡萄的气候变化适应策略

气候变化严重影响了地中海南部的葡萄种植，特别是在意大利坎帕尼亚等地区。本研究通过研究葡萄水分平衡与葡萄品质的关系，探讨气候变化对葡萄品种Greco的影响，为农民提供实践支持。在意大利圣保利纳（Avellino）的Feudi di San Gregorio酒庄的一个葡萄园进行了为期三年的田间试验，采用了各种土壤和树冠管理方法。利用收集的数据对SWAP农业水文模型进行校准和验证，分析土壤-植物-大气系统，评估气候变化情景（RCP 4.5和8.5）对葡萄品质的影响。结果表明，管理水分胁迫对于获得理想的葡萄品质至关重要，特别是在作物水分胁迫指数（CWSI）低于20% %的时候。在2010-2040年、2040-2070年和2070-2100年期间，与参考气候（RC）相比，在RCP 4.5情景下，预计水分胁迫将显著增加，平均分别增加7. %、9. %和8. %；在RCP 8.5情景下，预计水胁迫将平均增加4. %、9. %和14. %。本研究为农民适应气候变化，确保原产地控制保证区恢复力提供了实践支持。这项研究是坎帕尼亚地区资助的油脂项目的一部分，重点是希腊的可持续种植实践。
