The Graphiic Page: Random Update On World Agriculture; US Crude Oil Production -- March 3, 2019

From FAO, a definition, ha/hg:

The data reported under this element represent the harvested production per unit of harvested area for crop products. In most of the cases yield data are not recorded but obtained by dividing the data stored under production element by those recorded under element: area harvested. Data are recorded in hectogramme (100 grammes) per hectare (HG/HA).

Reminder: Thomas Robert Malthus, 1766 - 1834.

Worldwide, here is the productivity of land used for growing wheat:

I find that absolutely amazing. It is simply amazing how productive terra firma is for growing wheat. The y axis is productivity, hg/ha. The graphic is for wheat. 

Now, the next question, is more or less land being turned over to agriculture? Here's the data:

The y axis is hectares of land on a global basis. Again, I find that amazing, all the land that is being added over the years to grow wheat. I assume the same holds for corn, and other agricultural products, depending on demand.

To get to those graphs, start here. At that link, scroll down quite a ways.

US Crude Oil Production

From Mark Perry, last week:

Reminder: M. King Hubbert, 1903 -- 1989. Never lived to see the Bakken revolution, or as Art Berman calls it, the Bakken retirement party.
