As noted by the staff at the University of Otago, even in the event of such a nuclear war, there will be five countries that can withstand the aftermath of the conflict, including food shortages and widespread famine. Among them are states located on islands or peninsular territories, such as Iceland, New Zealand, Australia, the Solomon Islands, and Vanuatu.
Residents of these countries will survive because they will be able to maintain normal agricultural practices under conditions of reduced sunlight, the researchers stated.
The modeling results are published in the scientific journal Risk Analysis.
