Land sparing's global "brutal math" is inescapable: from 1961-2020, global population grew 2.6x and agricultural output increased nearly 4x, but total ag land grew by only about 7.6% and croplands by 20-25%. www.ers.usda.gov/amber-waves/.... 8/
Global Changes in Agricultural Production, Productivity, and Resource Use Over Six Decades | Economic Research Service
From 1961 to 2000, agricultural output nearly quadrupled, mostly achieved by increases in productivity as new resources were brought into the production process, the use of inputs intensified, and the...

My New Year's resolution is improve how I start Bluesky threads. I forget to announce what they're about. So: please check out this thread if you're either highly critical or gung-ho about the merits of the Green Revolution, "land-sparing" and maximizing yields using industrial agriculture.
I liked this conversation. I recommend it. But, in the hopes that listening to it doesn't just reaffirm people's prior attitudes, I want to highlight where @mikegrunwald.bsky.social & @adamcalo.bsky.social seem to talk past each other, regarding what causes deforestation, where and at what scale. 1/
A leftist academic wrote an essay titled "Useful Idiot" about...me! So I did his podcast, and it's kind of interesting. I like how he introduces me by explaining that usually his guests are insightful, but he decided to make an exception. landscapes.libsyn.com/more-is-less...

People complain about the price of eggs but eggs don't ruin your hope of a secure middle-class life. Housing does.

Summers called this female Chinese economist “peril.”
“Yellow peril” was partially built on the claim that Chinese women were sexually immoral threats.
That logic fueled the Page Act of 1875, which barred Chinese women by presuming they were prostitutes, even before the 1882 Chinese Exclusion Act.

Come for how we published a paper of null results & with no regression tables
Stay for new ways to proxy for crop yields & map hydrological relationships

No longer.

Trump sent an innocent man to a foreign prison and is ignoring a Supreme Court order to bring him back.
If this stands, he could do the same to anybody in the U.S., we no longer have rights, and the Constitution no longer has meaning.
