Study analyzing the relationship between climatic factors and grape production in Lanzarote between 2002 and 2010, using climatic data from the Tinajo station and production figures from the Lanzarote DO Regulatory Council.
Four key climatic factors that influence production volume are identified:
-
Autumn chill hours : Buds need cold days to break dormancy. In Lanzarote, the necessary levels are not reached, which can affect bud break.
-
Wind during the previous year's flowering (N-1): Strong winds during flowering can affect flower induction and lead to shoots without clusters the following year. This effect was evident in 2010 due to the winds of April 2009.
-
Rainfall volume : Water scarcity can reduce berry size or cause raisining, negatively affecting production.
-
Heat waves close to the harvest : Extreme heat can dehydrate grapes, causing significant volume losses, as happened in 2009, with a reduction of 25–30%.
The analysis shows how specific climatic conditions can directly or indirectly affect vineyard productivity in Lanzarote.
Viticulture and climate change in Lanzarote
The study “Climate and vineyard development; 2016 harvest” , prepared by Tomás Mesa in the plots of El Grifo, analyzes how the evolution of temperatures and the low accumulation of winter cold affect the vegetative cycle of the vine in Lanzarote.
Through data collected at the Masdache weather station and the Tinajo central station, phenomena such as heterogeneity in budding , the delay in the harvest and the reduction in the harvest observed in 2016 are documented.
This work is part of the research that the winery is developing to understand the impact of climate change on the island vineyard and to adapt its viticultural practices to an increasingly challenging environment.
