Climate change
Climate change is one of the most significant challenges currently facing society.
Forecasts of changing weather patterns present primary industries with particular challenges in how to predict, adapt to and mitigate against the impacts of climate change.
This section outlines the causes and effects of climate change, the impacts on primary industries, actions currently being undertaken by NSW DPI and identifies future research priorities.
As NSW DPI has undertaken climate-related research for more than a decade, the department is well placed to respond positively to the challenges ahead.
Discussion paper
Climate change research priorities for primary industries - discussion paper was launched on February 20, 2008. It outlines the issues and the priorities for science and research to respond to the challenge of climate change...Find out more ...
Causes of climate change
The Earth’s climate varies over times scales from months through to centuries and beyond. Factors that affect the climate over time-scales from hundreds to millions of years include... Find out more ...
Key issues
Fossil fuel combustion, for electricity and transport, and deforestation has increased carbon dioxide concentration to 36% above pre-industrial levels. Other greenhouse gases such as methane, nitrous oxide and water vapour also contribute significantly to the greenhouse effect. Find out more ...
Projected impacts on primary industries
Reduced winter and spring rainfall, and increasing temperatures are the major direct effects of climate change on primary industries in NSW. Indirect effects are greater pressure on water resource and greater incidence of fire.
Some of the potential impacts of these changes on NSW primary industries - Agriculture, Forestry, Fishing and Aquaculture, and Mining - are outlined. Find out more ...
Responding to climate change
Coal-fired power generation is the largest single contributor to NSW greenhouse gas emissions, so reducing emissions from this sector is critical to achieving substantial cuts in emissions.
Agriculture contributes 12% of Australia’s emissions, largely due to methane, from ruminant livestock digestion, and nitrous oxide from soils. More about how we can respond to climate change. Find out more ...
Research projects and priorities
NSW DPI research targets gaps in current knowledge in three distinct areas:
Modelling: to test the specific impacts of climate change on various primary industry sectors;
Mitigation: how primary industries can reduce their greenhouse footprint as well as sequester carbon to offset emissions from both primary industries and other sectors; and
Adaptation: adapt to changes in climate that are now inevitable due to past emissions.
