Winemakers have noticed grapes are maturing early and being harvested earlier than they used to.
- The region has experienced 20 of the past 21 years above average temperatures.
- Increase in temperatures affect time of harvest and in turn quality of grapes.
- Grape ripening is occurring .5 to 3 days earlier per year in Australia.
- Pinot noir grapes display the greatest sensitivity to climate change.
- Some regions can expect harvest to come 45 days earlier than normal by 2050.
- Some regions may also be adversely affected by grapes not meeting their chilling requirements.
- Up to 70% of Australia’s wine growing regions will be less suitable for grape growing by 2050.
- Central/Northern Victoria is expected to see a 16-52% decrease in wine grape quality by 2030.
- The wine industry contributed $7.6billion directly to the Victorian economy in 2015,this is expected to be disrupted.
- The wine industry contributed 13,000 jobs to the Victorian economy in 2015,this figure is expected to decrease.
- Changes will have to be made to agricultural practices and supply will be reduced, both of these factors will push wine prices up.
What can be done?
- Email your local MP and tell them that action on climate is important to you and explain the impacts being felt in your area. One email might not feel like much but most politicians consider it to be representative of 100 citizens.
- Help support the Act on Climate collective by donating; we are leading the charge for climate action. Your donation helps in advancing policies that prevent climate change from getting worse, we aim to empower communities and build a strong pro-climate-action constituency that governments can’t ignore, and as an added bonus it’s tax-deductable.
- Get involved with Act on Climate. We meet every Monday at 6pm (upstairs at 312 Smith St, Collingwood) and welcome all newcomers to join in the fight for climate justice. If you are unable to attend, follow us on Facebook, Twitter and Instagram to keep up with the latest campaign.
