In the coastal plains, it is a great place to farm. You definitely want to build wells, dams and irrigation systems to irrigate the land. You will want to trade in Aden, India, Persian Gulf, and the Red Sea.
In the mountains, you want to create mud bricks to build a house because those would be the best way to make a strong house. You want to build stone walls around narrow strips of land. You also want to farm pomegranates and melon. While you farm those, grow some trees to make myrrh and frankincense.
