• Tabique buildings heritage in the Alto Douro Wine Region, Portugal

  A comprehensive analysis of Tabique buildings in the UNESCO-listed Alto Douro Wine Region reveals that despite visible deterioration, these traditional timber-framed structures retain robust mechanical performance and structural integrity. The study, combining fieldwork, laboratory testing, numerical modeling, and statistical surveys, demonstrates that Tabique buildings exhibit satisfactory vertical load-bearing capacity, fire resistance, and thermal performance. However, it highlights a critical issue: current rehabilitation practices often involve the replacement of original timber systems with reinforced concrete or steel, which risks compromising heritage value. The research proposes a practitioner-oriented workflow for structural assessment and conservation, emphasizing the need for specialized preservation approaches that balance structural safety, regulatory compliance, and the protection of traditional construction techniques. This work provides a scientific foundation for sustainable interventions aimed at preserving the unique architectural legacy of the Alto Douro landscape.

• How can landscape visual assessment inform landscape planning and management? – Alto Douro Wine region case study, Portugal

  Landscape visual quality (LVQ) assessment is a powerful tool for monitoring and guiding landscape planning, particularly in UNESCO-recognized cultural landscapes like the Alto Douro Wine Region (ADWR). Research demonstrates that monitored areas within ADWR exhibit higher LVQ scores, characterized by imageability, color diversity, and land-use mosaics, while unmonitored regions with significant land-use changes show decreased visual quality. The study highlights that expansion of agricultural fields at the expense of traditional terraced vineyards and olive grove hedges negatively impacts aesthetic value. These findings underscore the importance of prioritizing conservation efforts for such features to maintain landscape integrity. The LVQ protocol, which evaluates physical, aesthetic, and psychophysical attributes, proves effective in identifying priority measures and tracking landscape evolution over time.

• Foliar application of nettle and Japanese knotweed extracts on Vitis vinifera : impact on phenylpropanoid biosynthesis and antioxidant activity during veraison and harvest of cv. Touriga Franca

  Foliar applications of nettle (Urtica spp.) and Japanese knotweed (Reynoutria japonica) extracts significantly enhanced bioactive compound content and antioxidant activity in Touriga Franca grapevines, a key variety in the Alto Douro Wine Region. Nettle extract increased total carotenoids in leaves and boosted phenolic content along with ferric reducing antioxidant power (FRAP) in berries, while Japanese knotweed extract elevated flavonoid levels in leaves and DPPH antioxidant activity in berries. Conducted over two growing seasons (2019–2020), the study demonstrates that these plant-based extracts can stimulate phenylpropanoid biosynthesis, improving grapevine physiological performance and berry quality—offering a sustainable approach to enhance wine quality without synthetic interventions.

• Exploratory approach for automatic detection of vine rows in terrace vineyards

  An exploratory approach combining remote sensing with artificial intelligence, including Machine Learning and Deep Learning, shows promise for automatically detecting vine rows in the complex terrace vineyards of the Alto Douro Wine Region. This method addresses a longstanding challenge in precision agriculture, where most studies have been limited to flat terrains. Preliminary results indicate successful detection of both straight and curved vine rows, even on the challenging slopes characteristic of this UNESCO-listed site. The approach could facilitate multi-temporal crop evaluation and production estimation, offering significant potential for sustainable winegrowing practices in this globally recognized region.

• Water Heritage in the Rural Hinterland Landscapes of the UNESCO Alto Douro Wine Region, Portugal: A Digital Humanities Approach

  A digital reconstruction of the water heritage landscape in the UNESCO Alto Douro Wine Region reveals how augmented reality can enhance archaeological interpretation by visualizing historical transformations. Using IT, Digital Humanities tools, and historical cartographic data, researchers mapped anthropic elements related to water and natural features along the Corgo River, providing a realistic view of this cultural and natural landscape's evolution over time.

• Paisagens Culturais da Vinha: Identidades, Desafios e Oportunidades. XX Aniversário da Classificação do Alto Douro Vinhateiro como Património Mundial

  A significant innovation in Douro winemaking emerged at the turn of the 20th century with the introduction and commercial success of sparkling wine, offering a viable alternative to the region's economic challenges. This study sheds light on how French winemaking techniques were adapted in the Douro, particularly in Lamego, where José Teixeira Rebelo Júnior and Adelino Pereira do Vale established a pioneering company that thrived both nationally and internationally. Through an analysis of newspapers, parish records, notarial documents, and private archives spanning 1880s to 1930s, the research reveals the entrepreneurial strategies and market dynamics that propelled this innovation. The findings highlight the region's capacity for adaptation, even amid crises, and its broader cultural significance as a UNESCO World Heritage Site.

• Viticulture under climate change: A case study on a water scarcity model

  A groundbreaking water scarcity model for viticulture, developed by ADVID/CoLAB VINES&WINES and the University of Trás-os-Montes and Alto Douro (UTAD), leverages a multi-sensor network to map vineyard water stress in real-time. This Decision Support System (DSS) utilizes LoRaWAN technology for remote data transmission, enabling continuous monitoring of soil, plant, and atmospheric parameters—critical for assessing the soil-plant-atmosphere continuum under climate change. The pilot, deployed in a commercial vineyard within the Douro Demarcated Region (DDR), offers a cost-effective alternative to traditional methods like the Scholander pressure bomb, addressing water scarcity challenges in remote areas with limited mobile network coverage. By integrating Machine Learning, this system aims to optimize water management, enhancing sustainability and competitiveness for winegrowers while contributing to broader water resource conservation efforts.
