Climate Change and Wine

"Vineyard and climate change" by Gregory Jones
 The global wine map is changing
 Climate change is one of many factors interacting to put
pressure on the wine sector, these include;
 National to international economics
 Growing demand, but changing demographics
 New markets, new consumers, new styles
 New purchasing trends
 Changes in the tastes of wine writers/raters
 Production and movement of bulk wine
Climate Change and Wine
Numerous impacts on the wine sector have been observed
in regions worldwide, including:
 Advanced phenology (~5-10 days per 1属C of warming):
early bud break increases frost risk, ripening now occurs
in a warmer period of the year
 Changes in soil moisture, drought frequency, and salinity
 Supply and timing of irrigation water
 Nature of changes, Tmax changes mean something
different than Tmin changes
Climate Change and Wine
Numerous impacts on the wine sector have been observed
in regions worldwide, including:
 Changes in cool season chilling, lack of dormancy
 Increasing impacts of heat stress on quality
 Higher humidity increasing disease pressure
 A warmer atmosphere increases thunderstorm frequency
and severity
 Sugar, acid, phenolics, and flavors out of balance
 Wine style changes
 Variety suitability changes
Climate Change and Wine
 The planet is warmer than at any time in our recorded
past, and continued warming is highly likely
 Modeling efforts indicate the potential for ~2-4属C
warming in wine regions globally by 2050-2070,
conservative estimates indicate ~1-3属C is highly likely
 However, the past 15 years many regions have already
produced conditions that were expected to be more
like on average by 2050
Climate Change and Wine
 Oceans are absorbing much of the heat, disrupting
biogeochemistry cycling and climate feedbacks
 Climate variability has been more pronounced in the
last 15-25 years; wider swings, more record extremes,
and increased severity and frequency in some aspects
of the climate
 Models are projecting continued increases in
variability, bringing further risk on top of the average
changes in climate
Climate Change and Wine
 Opportunities for a more sustainable wine sector through reduced
vulnerability and increased adaptive capacity should be addressed in
the industry and the research community:
 Realizing the large genetic potential for adaptation
 Realizing the large landscape potential for adaptation
 Potential changes in traditional training systems
 Optimization of canopy geometry, row orientation, and increasing
the use of shading materials
 Improved understanding of scion-rootstock combinations for a
regions soils and climate
 Improved grapevine water use efficiency and irrigation
management, where necessary/possible
Climate Change and Wine
MED-GOLD, Turning climate-related
information into added value for traditional
MEDiterranean Grape, OLive and Durum
wheat food systems, is a 4-year project
contributing to make European agriculture
and food systems more resilient, sustainable
and efficient in the face of climate change by
using climate services to minimize climate-
driven risks/costs and seize opportunities for
added value.
The Porto Protocol, a volunteer corporate
and institutional movement aimed at creating
a more sustainable environmental policy. The
Porto Protocol is an open platform, a dynamic
database of ideas, a shared resource from
which we can all benefit, whatever our area
of activity around the globe.
Thank You!
