Food security research typically focuses on gradual trends, but risks such as nuclear war and volcanic eruptions threaten large and abrupt declines in food security. This paper, published in the journal Solutions, describes alternative foods, which do not get energy from the Sun, as a solution for these catastrophes.
Isolated Refuges for Surviving Global Catastrophes
Refuges isolated from the broader human population could keep some people alive through a range of global catastrophe scenarios. This paper, published in the journal Futures, analyzes design characteristics refuges would need to succeed, such as their ability to operate independently and produce food for their residents.
Resilience to Global Food Supply Catastrophes
If humanity could survive major global food supply disruptions, it would be much less vulnerable to global catastrophe. This paper, published in the journal Environment Systems and Decisions, studies options to improve global food resilience, covering food stockpiles, agriculture, and alternative foods produced without sunlight.
