Wine producers leading climate change adaptation

February 22, 2013

A new study investigating wine regions' adaptation to climate change has found that many wine producers in South Australia's McLaren Vale are leading the world at responding to future risk.

The study, conducted by researchers at the University of Adelaide and Université Paris Diderot, has found that by making the now to adjust their viticultural systems, McLaren Vale wine producers are more likely to be resilient to unfavourable climatic conditions in the decades to come.

The study, led by French researcher Anne-Laure Lereboullet, compared two wine regions - McLaren Vale in Australia and Roussillon in France - and looked at the ability of each region to adapt to climate change at a social, ecological, agricultural and economic level.

"Viticultural systems in Mediterrranean climatic areas such as South Australia and southern France are projected to experience significant and rapid changes in climate over the coming decades," says study co-author Dr Douglas Bardsley, Senior Lecturer in Geography, Environment and Population at the University of Adelaide.

"By 2060 we expect to see decreases in rainfall by about 30% and increases in temperatures up to two degrees Celsius, which will place additional on and berries. This in turn will impact on the quality and quantity of wine produced," he says.

"By working in cooperation to secure their water and land resources, and experimenting with new approaches to make their distinctive wines, producers in McLaren Vale have established a resilient system that will help them to adapt.

"Local initiatives such as the scheme for irrigation, support for government policy to retain rural land use, and experimentation with viticultural practices including variety, mulching, pruning and harvesting, have all reduced local vulnerability to climate change.

"Other agricultural industries and regions could learn from these activities," Dr Bardsley says.

Dr Bardsley says that while these initiatives provide great flexibility for McLaren Vale in comparison to Roussillon, some producers in the region still have a lack of understanding of . "This could hinder their ability to adapt at a time when they should be considering the long-term impact for themselves and the region as a whole," he says.

The McLaren Vale region produces between 40-70,000 tonnes of wine grapes annually. In 2010, the region's grape crush had an estimated total value of $51.4 million and the region generated an overall contribution of more than $160 million in tourism revenue.

Dr Bardsley says the "viticultural challenge" will be to consistently produce high-quality wines for international markets in a warming, drying climate. "It is very difficult for producers to simultaneously adapt to both a changing climate and highly competitive market conditions," he says.

Science is telling the truth when they claim to have full consensus that climate change is real and "could" cause a crisis. Not one single IPCC warning isn't qualified with "maybe" and "could be" etc. Science has never said climate change "will" be a crisis or is "imminent". Only it's believers and media and politicians were the liars saying it "will" happen. And besides, would you deny what you are being paid to study the effects, not causes of an assumed to be real crisis? One would have to want this misery to be real and remain a believer.
How close to unstoppable warming will they take us before they say a crisis is imminent, not just "likely"?

They being me; global warming is going to kill us man. If we don't stop what we are doing, it's like game over man. Game over!

How hot do you want your summers to be? It's game over man, its too hot already.
