It kind of seems like a lot of dairy is exported. Dairy was valued at $10.4 billion, Cattle and Calves: $3.63 billion, Almonds: $3.52 billion. I mean, unless California is consuming over 70% of $14 billion in cattle and dairy products, but exporting all the almonds.
Well, I did a little analysis and almonds sure are a consumer of water in California, but I’d encourage you to look into the water, land use and emissions impact of cattle and dairy, I know, you are worried about exporting away all your water, but there are larger impact agricultural products and you said everything should be scrutinized more, so here is more scrutiny.
tl;dr: In 2022, California used this much water on these agricultural products: Almonds: 9 billion m³ Beef: 20 billion m³ Cheese: 4.4 billion m³ Butter: 1.3 billion m³
This doesn’t factor in other dairy products because the data doesn’t line up well enough to compute and I’m just some internet user, so what do I know?
Anyways land use is crazy, beef alone used 1 million acres, while all other field crops used 627 thousand acres. (Source: cdfa stat review)
