I am rapidly running out of big topics that I have never covered in my CB features, but groundwater was one of them until now. With severe drought becoming a common problem associated with the climate catastrophe (and not helped by catastrophic flooding that doesn't do much to replenish the aquifers), there have been a few worrying reports of shrinking groundwater supplies from around the world recently along with a call to recognise the groundwater as a keystone ecosystem. I've also been very excited to learn about the underground aqueducts of ancient Persia (picture below) known as qanats, many of which still provide a much more sustainable access to groundwater than modern day wells.
All of which is stitched together in my latest feature which is out now:

The thread for 2023 is here .
In ancient Persia, underground aqueducts known as qanats channelled groundwater to low-lying outlet points by gravity alone. Although some are still used in modern-day Iran, like the one shown here in Gonabad, many have been abandoned and replaced with deep wells operating less sustainably.
