Impact of climate change on some grapevine varieties grown in Peru for Pisco production

Abstract

Aim : The Peruvian region of Ica is an important area of grapevine cultivation, mainly for the production of pisco, the flagship hard drink of Peru. The effects of a changing climate have been assessed using the recorded temperatures of a weather station together with projected climates for the 21 st century generated under the A1B SRES scenario. Methods and results :The bioclimatic indices commonly used in grapevine studies have increased in recent years and will continue to rise along the 21 st century in relation to increasing temperature. In parallel, the phenology of four pisco cultivars (Quebranta, Torontel, Moscatel and Italia) has been experimentally assessed during four consecutive years, first to determine their cumulative growing degree-days and then to project them in past and future climates.Conclusion : It appears that the cycle lengths of these cultivars have been shortened in recent years and that this tendency will continue all along the 21 st century.Significance and impact of the study : Assessing the immediate and future impact of climate change makes it possible to identify potential crop production problems and provides information on adaptation strategies.

ApeX-Vigne: experiences in monitoring vine water status from within-field to regional scales using crowdsourcing data from a free mobile phone application

“…Numerous papers have shown that high temperatures tend to accelerate vine phenology (Yzarra et al 2015;Parker et al 2020). Even though the design of this work did not allow for a formal interpretation of these results, it is possible that the higher temperatures in the spring of the 2020 season accelerated phenology and favoured earlier shoot growth stop that year.…”

Caracterización y tipología de fincas productoras de vid para Pisco en la región Ica-Perú

“…Su clima es típicamente árido, la duración de la insolación diaria tiene un valor medio de 7 horas. La temperatura media es de 21 ° C con una media máxima de 29°C y una media mínima de 14 ° C, y la precipitación anual es de casi cero (cantidad a largo plazo de 2 mm) (Yzarra, et al, 2015, Abreu y Bannon, 1993.…”

Adapting the wine industry in China to climate change: challenges and opportunities

“…Change and Wine has been organized three times by the Wine Academy of Spain to address the need for climate change adaptation in viticulture (Li Y.B., 2015). Several investigations of climate change and viticulture are underway in France and other wineproducing countries (Ollat and Touzard, 2014b ;Yzarra et al, 2015). In France, the multidisciplinary LACCAVE project (long-term adaptation to climate change in viticulture and enology) involving 23 different laboratories from the National Institute for Agricultural Research of France (INRA), the National Center for Scientific Research (CNRS) and…”
