Hungry-Hungry Heated-Up Bugs

Crop losses due to insects could nearly double in Europe's bread basket due to climate,
University of Colorado at Boulder, August 30, 2018.

MAIN POINTS

Globally Warmed Insects
“...models increases in insect populations and their metabolic rates in a warmer world. It projects a 50 to 100 percent increase in pest-induced crop losses in European wheat and 30 to 40 percent increases in North American maize even if countries meet their existing commitments to reduce greenhouse gas emissions. “

"In some temperate countries, insect pest damage to crops is projected to rise sharply as temperatures continue to climb, putting serious pressure on grain producers...”

Future Bugs
“Future bugs, however, in a warmer climate are expected to be even hungrier and more numerous. Warmer temperatures have been shown to accelerate an individual insect's metabolic rate, leading it to consume more food during its lifespan.”

Europe
“The study finds that Europe's bread basket could be among the hardest hit. Currently the most productive wheat producing region in the world, pest impacts on European wheat could create total annual pest-induced yield losses that could top 16 million tons. Eleven European countries are predicted to see 75 percent or higher increases in insect-induced wheat losses, including the U.K., Denmark, Sweden and Ireland.”

US & China
“The U.S., the world's largest maize producer, could see an almost 40 percent increase in insect-induced maize losses under current climate warming trajectories, a reduction of over 20 million tons annually. Meanwhile, one-third of the world's rice production comes from China, where future insect-induced losses could top 27 million tons annually.”

Double-Wammy
“...the impacts from insects add up to about a 2.5 percent reduction in crop yield for every degree Celsius increase in temperature," said Tewksbury. "For context, this is about half the estimated direct impact of temperature change on crop yields, but in north temperate areas, the impact of increases insect damage will likely be greater than the direct impact of climate on crop yields."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
