A lot of talk about availability of water. How much land is available east of the Mississippi? Are there large tracts of farm land now unused? Maybe everyone there could have a back yard garden to relieve the need for large farms in the west. I’ll look somewhere other that the NYT for advice about agriculture (or anything else for that matter).
It is a myth that we are running out of farm land anywhere in this country.
There is a lot of land lying fallow, and as someone has observed, even returning to forest. In my work I drive around much of Northeast Ohio, which most people would consider an industrial area, but all I see is countryside-- and much of it not being farmed, although it has been in the past and could easily be again. I expect it is not atypical of much of the Eastern US, at least away from the seaboard.
The authors btw are "climate scientists" from Alabama, not NY.
