Which areas of south Asia are sparsely populated

Coastal areas
Areas with arid climate
Areas with heavy rainfall
Areas in the humid temperature climate region

Some of the areas in South Asia that are sparsely populated include:

1. Mountainous regions: High-altitude mountainous areas such as the Himalayas in Nepal, Bhutan, and parts of northern India are sparsely populated due to the harsh climates, difficult terrain, and limited agricultural opportunities.

2. Deserts: The Thar Desert in Rajasthan, India, and parts of southwestern Pakistan are sparsely populated due to the arid climate and lack of water resources.

3. Coastal regions: While some coastal areas in South Asia are densely populated due to economic activities like trade and fishing, there are also sparsely populated coastal regions. These areas might lack infrastructure and economic development, such as certain parts of the Sundarbans mangrove forest in Bangladesh.

4. Forested regions: Dense tropical rainforests in South Asia, such as parts of Assam and Arunachal Pradesh in India or parts of Myanmar, can be sparsely populated due to the challenges presented by the dense vegetation and lack of accessibility.

It's important to note that population density can also vary within these regions, and some areas might be sparsely populated while others are more densely populated.
