Zoom Address. all welcome:

Earth is in overshoot. The cumulative impact of 8 billion humans, relentlessly pursuing economic growth, has stressed the planet beyond its limits. The symptoms include climate change, the biodiversity crisis, food and freshwater shortages. We can either do nothing and wait for the ‘crash landing’ or do something now to prevent an all-out crash.
Economic alternatives for escaping overshoot include a planned economic contraction. This would reduce the potential for further social, environmental and economic impacts. Other potential solutions include doughnut economics, regenerative economics and degrowth. ‘Green growth’ is often offered as a solution, but the continued emphasis on ‘growth’ is problematic. Aside from economic, physical and biological impacts of economic growth, another serious problem is growing inequality and finding an equitable way out of the current situation.
Many New Zealanders are already doing their bit. Joining the panel discussion are a farmer and a farm management specialist, who are working on ways that lowering inputs (such as energy and fertilizer) can actually increase economic benefits. Another important strand in the discussion is how cultural factors, including migration and colonisation, have been important in how New Zealand got to where we are now. Cultural factors are also critical in solving our current problems and finding a more sustainable way to live.
This panel discussion will range from the wider picture of problems caused by economic growth, in New Zealand and internationally, to local, personal solutions.

Barrie Ridler is an Agricultural Analyst and the Director of E2M. He has a BSc Honours from Massey University, in Agricultural Economics and Farm Management, and developed the E2M Enviro-Economic Model. Barrie was a Senior Lecturer in Agricultural Systems for 11 years and also has many years of experience as a farmer and farm manager. Barrie uses his expertise in agricultural economics and farm management, applying marginal analysis to provide innovative solutions to any farm system. From an economic perspective a thorough understanding of profit maximisation is required to optimise a system but one cannot profit maximise without knowing a farm’s marginal cost and marginal revenue. A systems model (GSL model) utilises resource allocation to ensure “best fit” of resources to the outcome(s) required. This allows resource allocation that provides the best economic and environmental outcome. Marginal analysis is especially useful for making these kinds of decisions as it accounts for the non-linear nature of such systems.
