Researchers identify agriculture that could survive a sun-blocking catastrophe. Click the link to read more.
, the journal of the Royal Swedish Academy of Sciences, the study became more relevant as Russia invaded Ukraine and renewed fears of nuclear conflict.
Such an exchange would reduce the levels of sunlight to less than 40 percent near the equator, and less than five percent near the poles, compared to normal says the study. Temperate regions worldwide would endure freezing temperatures and severe precipitation reductions. And conditions would likely take up to 15 years to fully recover.
To do this, researchers determined population centers close to forested, tropical regions, and chose both tropical dry and wet forests. Next, they examined a list of 247 wild, edible plants and chose 33 that could hold farming or foraging potential in post-nuclear war conditions. “The amount of calories in fat and protein that are condensed in those grubs are immense,” Winstead says. “You can feed someone’s entire caloric needs with 30 or 40 Tupperware containers of palm weevils, and all you have to do is just continually harvest them. And you can fit that in the corner of a room.”
“[It’s] basically a banana tree that you eat the tree instead of the banana,” Winstead says, noting that the plant prevented starvation during Ethiopian famines. “Biodiversity isn’t just pretty to look at,” Winstead says. “There are a lot of uses here, and there’s thousands and thousands of edible plants that people eat across the world. It’s just that much more important to protect those areas so we don’t lose that biodiversity.”
