Climate change impact on a wine-producing region using a dynamical downscaling ...
Blanco-Ward, Daniel; Monteiro, Alexandra; Lopes, Myriam; Borrego, Carlos S.; Silveira, Carlos; Viceto, Carolina; Rocha, Alfredo; Ribeiro, A.C.Climate change is of major relevance to wine production as most of the winegrowing regions of the world are located within relatively narrow latitudinal bands with average growing-season temperatures (GSTs) limited to 13–21 C. This study focuses on the incidence of climate variables and indices that are relevant both for climate change assessment and for grape production, with emphasis on grapevine bioclimatic ...
Physiological response of the grapevine cultivars Touriga Nacional and Touriga ...
Ribeiro, A.C.; Barreales, David; Andrade, João Verdial; Rodrigues, M.A.; Blanco-Ward, Daniel; Monteiro, Alexandra; Lopes, Myriam; Borrego, Carlos S.The behaviour of the cultivars Touriga Nacional and Touriga Franca (Vitis vinifera L.), was studied under increasing summer stress conditions across Douro valley in the Demarcated Region of Douro - Portugal. The Douro region is divided into three climatic subregions: Baixo Corgo (BC), Cima Corgo (CC), and Douro Superior (DS) whose weather characteristics are presented and discussed in this study. In the Douro v...
Avaliação do risco de efeito fitotóxico do ozono troposférico em ambientes Medi...
Blanco-Ward, Daniel; Miranda, Ana Isabel; Silveira, Carlos; Ascenso, Ana; Gama, Carla; Monteiro, Alexandra; Lopes, Myriam; Borrego, Carlos S.Existe uma preocupação crescente com os possíveis efeitos das alterações climáticas na indústria vitivinícola em relação à produtividade da vinha e à qualidade do vinho. Um estudo de campo que envolveu medições de ozono superficial, medições meteorológicas e observações fenológicas da vinha foi realizado numa área de produção de vinhos de renome internacional, a Região Demarcada do Douro (RDD). A avaliação dos ...
Efecto del riego deficitario en los cultivares Touriga Nacional y Touriga Franc...
Barreales, David; Andrade, João Verdial; Feliciano, Manuel; Castro, João Paulo; Rodrigues, M.A.; Blanco-Ward, Daniel; Miranda, Ana IsabelEl principal factor ambiental que limita la producción de uvas en cantidad y calidad en la mayoría de las regiones productoras de vino del mundo es la falta de agua en determinados momentos de su ciclo de cultivo. Así, se están buscando estrategias para mitigar el efecto de la sequía. El riego deficitario (DI) es una de las estrategias que mejores resultados proporciona. Con este tipo de riego se pretende aport...
Sintese Conclusiva
Miranda, Ana Isabel; Rocha, Alfredo; Ribeiro, A.C.; Silveira, Carlos; Blanco-Ward, Daniel; Ascenso, Ana; Lopes, Myriam; Borrego, Carlos S.Este livro apresenta os principais resultados do projeto DOUROZONE, que teve como objetivo avaliar o efeito do ozono troposférico nas vinhas da Região Demarcada do Douro, em clima presente e clima futuro. Efetuaram-se simulações de clima e de ozono troposférico, com uma elevada resolução espaço-temporal. As simulações climáticas, para o clima histórico recente (1986-2005), futuro de médio prazo (2046-2065) e de...
Assessing the risk of tropospheric ozone phytotoxic effect on Southern European...
Blanco-Ward, Daniel; Miranda, Ana Isabel; Silveira, Carlos; Ascenso, Ana; Gama, Carla; Monteiro, Alexandra; Lopes, Myriam; Borrego, Carlos S.Tropospheric ozone in Southern Europe has an increasing tendency in association with a greater incidence of warm summers and heatwaves. As there is already much evidence of the negative effects that current ambient ozone has on vegetation, there is a need for consistent risk assessment methods. Ozone plant exposure-based parameters have been used extensively to support decision-making. However, these parameters...
Analysis of climate change indices in relation to wine production: a case study...
Blanco-Ward, Daniel; Monteiro, Alexandra; Lopes, Myriam; Borrego, Carlos S.; Silveira, Carlos; Viceto, Carolina; Rocha, Alfredo; Ribeiro, A.C.Climate change is of major relevance to wine production as most of the wine-growing regions of the world, in particular the Douro region, are located within relatively narrow latitudinal bands with average growing season temperatures limited to 13–21◦C. This study focuses on the incidence of climate variables and indices that are relevant both for climate change detection and for grape production with particula...

Blanco-Ward, Daniel; Monteiro, Alexandra; Lopes, Myriam; Borrego, Carlos S.; Silveira, Carlos; Miranda, Ana Isabel; Viceto, Carolina; Rocha, AlfredoClimate change is of major relevance to wine production as most of the wine-growing regions of the world, in particular the Douro region, are located within relatively narrow latitudinal bands with average growing season temperatures limited to 13-21ºC. This study focuses on the temporal variability of three grapevine bioclimatic indices, which are commonly used as part of the Geoviticulture Multicriteria Clima...
