Professor Anita Wreford is an applied economist at Lincoln University who specialises in adaptation to climate change with a particular focus on agriculture and the primary sector. She pointed out that scientists have been saying for decades that climate change is a problem, and time has been wasted when we could have been taking action.
We’ve all seen changes in weather patterns, and extreme weather events can now definitely be attributed to climate change. In 2021 the Intergovernmental Panel on Climate Control (IPCC) finally said it is “unequivocal that human influence has warmed the planet”, having previously used less strong language. The Paris Agreement was an international commitment to reduce emissions and keep global temperature rises below 2° above pre-industrial levels. Every degree of change matters!
Our agricultural systems in Aotearoa have evolved around a stable climate. Land is a critical resource which we rely on for food, and it is already under pressure. We are seeing changes in seasonality and average conditions, and the future impacts of climate change are complex and uncertain. Different pathways are possible and we need to be informed and flexible in our decision-making. Aotearoa is different from other countries because 50% of our emissions come from agriculture. We have great aspirations, but no policies or actions to achieve them. Policy is changing rapidly with alternatives to the Emissions Trading Scheme suggested by He Waka Eke Noa.
There are effective adaptation and mitigation options, and early action is likely to be more effective and cheaper. What is needed is long term decisions, which are difficult within the short term political cycle. One action we can all take is to talk to our local M.P. and let them know that climate change is important.
There’s so much more needs to be done
