I really enjoyed James’s lecture on irrigation. I knew some of the information he presented but I definitely didn’t know the fun facts that he had up his sleeve. For example, only 20% of the world’s farmland is irrigated and this irrigated farmland produces 40% of the food supply! That’s very efficient for such little irrigated land. We learned about different types of irrigation like drip/trickle which is expensive and efficient so they use it a lot out in California and systems like center/ pivot and furrow irrigation which aren’t as efficient. The most widely used irrigation system is center/pivot, which why when you travel in a plane and look down you will see a bunch of circles on the ground; those circles are the center/ pivot irrigated fields. Asia actually has the largest amount of irrigated land which is cool to me because they also will have the largest population by the year 2050.
