Want to survive comfortably in 600 C.E. on the Arabian Penisula then you need to read this article. First off the desert is extremley hot and cold. So in the summer or day you’ll most likely need the light color and light weight clothing to keep the heat from getting to you. Also it isnt easy to wander around lugging tons of bags and tools around so camels are helpful things to have. They can go for days without nescesties and carry all your needs. There nickname was the ship of the desert. But the Arabian Penisula wasn’t all bad, in fact there were pockets of tropical wonderlands in middles of deserts. Imagine clean, fresh water and lots of amazong fruits and animals to keep you nice and full. I’d suggest becomeing sedantary here where you have many luxuries. Such as the date palm, use this palm to make irrigation pipes to water your crops. Need a sturdy house? Use the date palms leaves and branches to make one. But there’s things you’ll need outside this little wonderland. Use the trade routes freqeuntly to go to market palces to get what you may feel you need. The coastal palin wasnt to bad either. A nice steady water supply and ports for trade and nesscisties. Dams are helpful but watch out, if it isnt strong then it could collaspe and flood and peraps kill lots of people. Wells are the safer way to go but may be more dangerous thanks to all the tribes gaurding their wells. Use some rivers to help irrigate your lands. Overall coastal plains could be simple and a nice place to settle down in. The last enviroment is the mountains. Terraces is the survival item that is key here. It stores water on hills and helps expand your land taking advantage of the before unusable land. Build a house with maybe some stones and logs and you’ll be set. Oh the water sources? No problem, 20 inches of rain and riverbeds you’ll be fine. Good luck on this incredible expedition for adventure!
