I suspect that you thought of something along the lines of Oklahoma or somewhere else along the Great Plains, but what if I told you to add Saudi Arabia to that list. Sounds weird, right? A desert growing wheat? Something seems wrong.
Nope! It is true. Saudi Arabia, a country made of mostly desert land is, in fact, practicing agriculture in the center of it all. This was all possible because of irrigation and it's not a new technique in fact. We practice the same thing in the United States, in areas like the desert regions of Nevada. This seems like a good idea for the economy perhaps (although it would take a lot to set up such a system), but what about the water supply? In these regions up to 90% of the water can be lost to evaporation. There is actually a new idea called the Sahara Forest Project which is an organization which is trying to create a sustainable way to supply water to desert regions on a wide scale. This would all be possible due to algae-based biomass cultivation, saltwater desalination, and solar thermal energy production. Sounds complicated right? Basically, the facilities would transform algae through photosynthesis into energy-rich biofuel. Still sounds complicated? Well, trust me, it is going to be cool.
