Where did sedentary people settle in the Arabian peninsula?

Sedentary people in the Arabian Peninsula primarily settled in areas with access to water and fertile land, such as around the oases, river valleys, and coastal regions. Key locations included the oases of Al-Ahsa and Al-Qatif in the Eastern Province, as well as agricultural settlements in the highlands of Yemen. These areas provided the necessary resources for farming and supported the development of trade routes and urban centers.
