The other day I saw a hysterical tweet on the same subject, with Tamar Haspel (a good writer on food issues) countering.
This morning for no reason I decided to Google AFIDA and found the active list of FSA AFIDA reports. The last report on this one is for 2016.
It starts with:
Foreign individuals and entities reported holding an interest in 28.3 million acres of U.S. agricultural land as of December 31, 2016. This is 2.2 percent of all privately held U.S. agricultural land and approximately 1 percent of all land in the United States (see fig. 1 for State-level detail).
