Rural Kiwis less likely to be admitted to hospital
New research has found that rural New Zealanders are less likely to be admitted to a hospital.
The new study, from Professor Nick Wilson of the University of Otago, and independent researcher Dr Matt Boyd, from Adapt Research, claims a total of five island nations, including New Zealand, could be well placed to continue producing food despite the reduced sunlight and cooler temperatures caused by soot in the atmosphere following a nuclear war in the Northern Hemisphere.
The other four nations were Australia, Iceland, Vanuatu, and the Solomon Islands.
Wilson says that while New Zealand was likely to continue to be able to produce enough food, its production and distribution was still threatened by the country’s dependence on imported commodities, such as refined fuel.
The researchers investigated the impact of abrupt sunlight reducing scenarios - including nuclear war, super volcano eruptions, and asteroid impacts – on agricultural production globally.
They applied published crop models under ‘nuclear winter’ conditions to 38 island nations, combining this with other methods to estimate the food calorie supply. They also assessed a range of resilience factors that might protect countries from the impacts of a nuclear winter.
Boyd says although some other nations would likely be able to produce enough food, but other factors, like the collapse of industry and social functioning, placed their resilience in doubt.
Wilson says the findings are consistent with a 1980s study on the impact of nuclear war on New Zealand, although the country’s resilience has declined since then as its dependence on imported diesel and digital infrastructure has increased.
“Islands such as New Zealand are often very dependent on imports of refined liquid fuel, may lack energy self-sufficiency and are susceptible to breakdowns and shortages of critical commodities,” Wilson says.
“While New Zealand could divert a high proportion of its dairy exports to supply the local market, it lacks the ability to manufacture many replacement parts for farm and food processing machinery,” he adds.

Meanwhile, Boyd says the findings reinforce the precarious position many countries would find themselves in during a global catastrophe.
“New Zealand has the potential to preserve an industrial society through this kind of catastrophe, but it is not ‘plug-and-play’,” he says. “A decent amount of strategic planning needs to happen and across a long period of time, but this planning would have benefits in dealing with a wide range of extreme risks.”
Boyd says the findings show a need to analyse nuclear winter and other abrupt sunlight reducing scenarios as part of a comprehensive national risk assessment.
“We are not aware of any plan for this kind of global catastrophe, including whether priorities for rationing have been considered.
“With the Government expected to release New Zealand’s first National Security Strategy this year it is important that the catastrophic risks associated with abrupt sunlight reducing scenarios do not slip through the cracks.”
