You need diversity in the room and a collective approach.” Limestone Coast “It’s a useful resource but also a very dense document and unpacking it is a challenge. The region was successful in obtaining support from the Victorian State Government to plan for its future and will conduct two more workshops where the region will be able to drill down into the information in the Atlas. The past 20 years have seen change already,” he said. “Climate change is something that everyone is dealing with. It’s the younger generation that will make changes, they bring new energy and capacity, whether they are descendants of the original growers or new entrants. “Growers in their sixties are less likely to make big changes. Mr Campbell said the horizon that was being used from the Atlas depended on the enterprise and to some extent on the age of the grapegrowers. “There’s no money to talk about completely new plantings but people are talking about reworking to warmer Mediterranean vine types such as Nero d Avola and Fiano.” “We can plan how to deal with more arid conditions, better soil moisture management and scheduling, and there is a lot of conversation around new varieties. More summer rain will mean more disease pressure and we can look at how we will adapt our management to deal with that. “Our region sees the Atlas as a great tool to unpack the local impact of climate change,” Mr Campbell said. The consequences are likely to mean earlier harvesting – due to the additional heat degree days and hotter conditions – but more critically for the region, where many grape crops were affected by smoke damage from fires in 20, there is concern about the increased potential for fire events close to vintage. The seminars brought in viticultural experts Professor Snow Barlow and Ben Rose to provide a sense of what the climate changes predicted in the Atlas mean in terms of viticultural practice.įor the North East Victoria region, the Atlas broadly predicts more heatwaves, slightly less rain overall and more summer rain. They organised a series of seminars for the four distinct sub-regions King Valley, Alpine Valleys (including Glen Rowan), Beechworth and Rutherglen, which were attended by more than 80 people. Lachlan Campbell from the North East Victoria Wine Zone said his region had approached the Atlas as a vehicle to support future planning and decision making. This article outlines the ways in which a number of different wine regions and wine companies have used the Atlas to date. The Atlas was intended to inform decision-making for the grape and wine sector and since its release different regions and businesses have been using it as a strategic tool to inform their future planning. This allows growers and winemakers to look to their peers and viticultural experts in analogue regions for ideas on how to adapt for their future. In addition, the Atlas indicates the regions around the country that are similar now to projected conditions. The indices include rainfall, rainfall timing, aridity, heat accumulation and the likelihood of heatwaves and frost. The project identified weather risks that are particularly important to grape growing and assessed future changes in their frequency and intensity based on regional climate models that incorporate the large-scale climate drivers impacting drought and extreme heat. The Atlas provides a range of viticulture specific indices to model changes to the climate, in 10 year increments out to 2100 for each of Australia’s 65 wine regions. Wine Australia’s Australia’s Wine Future: A Climate Atlas, was released in 2020, following three years of research by the University of Tasmania’s Climate Futures team.
