Today, Tuesday, was a regular class day, with two more to go. I had reserved the best for last, and today the lecture was about drought and how to manage it, which I happen to think is a pretty cool subject. Part of it is that there are so many interesting side subjects, such as the record of droughts in
over the last 1,000 years, or the question of whether droughts are linked to
climate change or are simply the result of precipitation being a random
process. And how do you manage a random process?
I normally follow with the ways available to society for the mitigation of drought impacts, which is a rather long discussion that branches into engineering, preparedness, and society’s perception. Given that groundwater use is one of the main tools we have to make up for dwindling surface water supplies, I then end talking about sustainable management of water resources (can you sustainable manage a random process?).
