This study summarizes the implementation process of precision viticulture technologies and analyzes their contributions to high yield and sustainability through case studies. The core technologies of precision viticulture include remote sensing and drones, sensor networks, Geographic Information Systems (GIS), and machine learning data analytics. Specific case studies demonstrate that a French winery significantly increased grape yield through precision irrigation; an Italian vineyard used AI to predict diseases and apply pesticides precisely, reducing chemical inputs; an Australian vineyard reduced irrigation water usage by 50% using sensor networks; and a California vineyard optimized harvest timing with remote sensing to enhance fruit sugar content. The study reveals that these technologies not only improve resource utilization efficiency but also reduce the use of fertilizers and pesticides, mitigate environmental impacts, and offer effective support for addressing climate change. Precision viticulture plays a vital role in achieving high yields and sustainability, providing practical references for the digital transformation of agriculture. Keywords Grapes; Precision viticulture; High yield; Sustainable agriculture; Artificial intelligence 1 Introduction Grape cultivation holds significant economic and agricultural importance globally, as grapes are one of the most widely grown commercial fruit crops and a key component of the wine industry (Ozdemir et al., 2017). The demand for high-quality grapes has driven the adoption of innovative agricultural practices, such as precision viticulture, which leverages advanced technologies to enhance production efficiency and sustainability (Spachos and Gregori, 2019). Precision agriculture technology, particularly precision viticulture, plays a crucial role in modern grape cultivation. It involves the use of technologies like GPS, remote sensing, and IoT to monitor and manage vineyard variability, thereby improving grape quality and yield while minimizing environmental impacts (Ozdemir et al., 2017; Pero et al., 2024). These technologies enable site-specific management practices, such as variable rate irrigation and nutrient application, which have been shown to reduce greenhouse gas emissions and improve resource use efficiency (Balafoutis et al., 2017; Pereyra et al., 2022). Traditional grape cultivation methods face several challenges, including the impacts of climate change and resource waste. Water scarcity, exacerbated by climate change, threatens the economic viability of grape production, necessitating efficient water management strategies (Finco et al., 2022). Additionally, conventional practices often lead to resource inefficiencies and increased environmental footprints, highlighting the need for more sustainable approaches (Balafoutis et al., 2017; Marcu et al., 2022). This study will analyze relevant case studies to summarize the implementation process of precision grape cultivation techniques and explore their effectiveness in improving yield and achieving sustainability. This research provides insights for researchers on how precision grape cultivation addresses the challenges faced by traditional methods and promotes the sustainable development of the grape industry.
