One reason that explains why areas of South Asia with arid climates are not densely populated is the scarcity of water resources. Arid climates are characterized by low precipitation and high evaporation rates, resulting in a limited supply of fresh water. Without access to sufficient water for drinking, agriculture, and other essential needs, it becomes challenging for populations to thrive in these regions. Limited water availability also hinders the establishment of industries and infrastructure, which further discourages population growth and economic development. As a result, these areas remain sparsely populated compared to regions with more favorable climates and abundant water resources.
