Yesterday I wrote about the use of water in dry areas of the world for all daily-life purposes. Among them was agriculture. I’d like revive the line of thought I left you with yesterday. This time to focus mainly on the resources used to create farms. Yes, farms in dry lands.
“Fossil water also enables crops to be grown in the desert to provide food for local populations.” A curious and ingenious system is used: farms gain a circular shape due to being irrigated around a central pivot. Growing crop is not only easier, but it’s also cheaper (within the otherwise average costs. Growing food in these areas is still very expensive). Dozens of these fields are constructed next to each other; bringing short-lived hope to farmers that can spend money to grow food where otherwise would have been impossible or unprofitable.
Again: short-lived. This circular system is used all over the world (such as the central U.S.A.) but in remote areas as this “there’s a heavy price to pay: fossil water is a non-renewable resource. In Saudi Arabia, the dream of industrial farming has faded.” All the money invested goes to waste, as more fossil water deposits are misused and overused, leaving investors bankrupt and, “as if on a parchment map, the light spots on this patchwork show abandoned plots. The irrigation equipment is still there, the energy to pump water also, but the fossil water reserves are severely depleted.”
