Climate change in our region
What is climate change and what does it mean for the Macedon Ranges?
The term 'climate change' refers to changes in our climate over time, from global to local scales. It includes changes in temperature (averages, minimums, maximums), rainfall, frequency and severity of extreme weather events, sea levels and wind patterns. While there have always been some changes in the earth’s climate, it is now well accepted that the significant changes in climate experienced over the past hundred years are due to human activity.
Climate change is caused by increased concentrations of greenhouse gases in the atmosphere, which trap heat close to the earth’s surface. The increase results from activities like extraction and burning of fossil fuels, deforestation and land clearing, and waste disposal and decomposition. While we can avoid the worst effects of climate change by reducing greenhouse gas emissions, some impacts are unavoidable and are already being experienced by many people and ecosystems around the globe.
Work undertaken by the Victorian Government, in partnership with the Bureau of Meteorology (BoM) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO), resulted in the Victorian Climate Projections 2019. More information can be found at a state and regional level:
The forecast changes in climate for the shire will impact across all sectors in the shire into the future, for example, an annual decrease of 20mm in rainfall in the region will impact on food production; water supply for consumption and for watering parks, gardens and sportsgrounds; waterway health; and potentially the species composition of vegetation communities and therefore food supply for different species of wildlife.

Key plans and reports on climate change
Climate Ready Loddon Mallee
Climate Ready Loddon Mallee is the regional adaptation plan covering Macedon Ranges Shire and nine other local government areas. It has been developed through the Victorian Government, in accordance with Victoria’s Climate Change Adaptation Plan 2017-2020, and is a guide for the Loddon Mallee to be a climate ready, sustainable and healthy region.
The plan lists goals and priority actions for people, places and sectors, based on four planning resilience themes, namely: knowledge, connection, wellbeing and security. The goals and actions have been informed through a mix of community engagement projects, to be a co-designed regional plan.
The final version of the plan is being prepared as at July 2021, and will be published online at ADAPT Loddon Mallee.

Loddon Mallee Regional Renewable Energy Roadmap
The Loddon Mallee Renewable Energy Roadmap was released in 2020, and provides an overview of the opportunities and challenges the region faces as it transitions away from fossil fuel-based energy towards a decentralised supply of renewable energy.
It looks at scales of generation, distributed energy resources, limitations and options for grid transmission, and the benefits that renewable energy projects may bring to regional economies and communities.
